DETAILED ACTION
This communication is in response to the claims filed on 01/11/2024.
Application No: 18/578,553
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Notice of Pre-AIA or AIA Status
In the event the determination of the status of the application as subject to AIA 35 U. S. C. 102 and 103 (or as subject to pre-AIA 35 U. S. C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 22-23 and 30-31 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim is drawn to a "computer program product … “
Regarding claim 22 (independent claim), the claimed invention is directed to non-statutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because claim 22 recites “ A computer program comprising program code to be executed by processing circuitry of a communication device …,” where the only limitations in the claim as a whole are directed solely to the program which is purely a data structure and thus non-statutory subject matter. Data structures not claimed as embodied in a non-transitory computer readable medium are descriptive material per se and are not statutory because they are not capable of causing functional change in the computer (i.e. a software program is merely a set of instructions capable of being executed by a computer, the software program itself is not a process. Further, the descriptions or expressions of the programs, are not physical “things,” they are neither computer components nor statutory processes, as they are not “acts” being performed. Such claimed computer programs do not define any structural and functional interrelationships between the computer program and other claimed elements of a computer which permit the computer program’s functionality to be realized).
Further, see MPEP, Warmerdam, 33 F.3d at 1361, 31 USPQ2d at 1754 (claim to a data structure per se held non-statutory).
Therefore, since claim 22 taken as whole is directed to a "computer program per se” embodiment, the claim is rejected under 35 U.S.C 101 as ineligible.
Dependent claim 23 is rejected for the same reasons as corresponding independent claim.
Regarding claim 30 (independent claim), the claimed invention is directed to non-statutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because claim 30 recites “ A computer program comprising program code to be executed by processing circuitry of a network node …,” where the only limitations in the claim as a whole are directed solely to the program which is purely a data structure and thus non-statutory subject matter. Data structures not claimed as embodied in a non-transitory computer readable medium are descriptive material per se and are not statutory because they are not capable of causing functional change in the computer (i.e. a software program is merely a set of instructions capable of being executed by a computer, the software program itself is not a process. Further, the descriptions or expressions of the programs, are not physical “things,” they are neither computer components nor statutory processes, as they are not “acts” being performed. Such claimed computer programs do not define any structural and functional interrelationships between the computer program and other claimed elements of a computer which permit the computer program’s functionality to be realized).
Further, see MPEP, Warmerdam, 33 F.3d at 1361, 31 USPQ2d at 1754 (claim to a data structure per se held non-statutory).
Therefore, since claim 30 taken as whole is directed to a "computer program per se” embodiment, the claim is rejected under 35 U.S.C 101 as ineligible.
Dependent claim 31 is rejected for the same reasons as corresponding independent claim.

The factual inquiries set forth in Graham v. John Deere Co., 383 U. S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U. S. C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1-17, 20-23 and 28-31 are rejected under 35 U. S. C. 103 as being unpatentable over Ramachandra et al. (US 20220182850 A1) in view of OLSSON et al. ( US 20110250880 A1).
Regarding claim 1, Ramachandra teaches a method performed by a communication device for communicating with a wireless network ([0195], e.g. FIG. 16 is a flow chart of a method 1200 in a wireless device (e.g., a UE), in accordance with certain embodiments. The method begins at step 1202, where the wireless device obtains an MDT configuration, wherein the obtained MDT configuration is for one or more of immediate MDT and logged MDT. In certain embodiments, the MDT configuration may be obtained from a RAN node. [0019] Signalling-based MDT: MDT data is collected from one specific UE. The UE that is participating in the MDT data collection is specified as IMEI(SV) or as IMSI. The signalling-based MDT is an enhancement of the signalling-based subscriber and equipment trace. The signalling-based MDT can be either a logged MDT or Immediate MDT), the method comprising:
receiving a signalling based logged minimization of drive test, MDT, configuration from a first network node belonging to a first radio access technology, RAT ( [0020], e.g. For signaling-based MDT (i.e., UE-specific MDT), the MDT control and configuration parameters are sent by the Network Management to a Mobility Management Entity (MME), which then forwards the parameters to the eNB associated with the specific UE. [0217] FIG. 18 illustrates another method 1400 performed by a wireless device 310 (e.g., a UE) for configured MDT reporting, in accordance with certain embodiments. The method begins at step 1402 when wireless device 310 obtains a MDT configuration. The obtained MDT configuration is for one or more of immediate MDT and logged MDT and is for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data (i.e. receiving signalling based logged minimization of drive test, MDT, configuration));
the signalling based logged MDT configuration comprising a first public land mobile network, PLMN, identity list ([0127], e.g. At step 110, the RAN node configures a UE based on the MDT scope either for immediate or logged MDT or both. At step 120, the RAN node obtains an MDT report from the UE. At step 130, the RAN node provides a MDT report to OAM. [0131] Network 306 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs or PLMN), … and other networks to enable communication between devices). [0045] the control and report associated parameters include: [0051] MDT PLMN List (i.e. the signalling based logged MDT configuration comprising PLMN, identity list). [0196] In certain embodiments, the obtained MDT configuration may comprise an indication of whether or not location information is requested by OAM (i.e. the indication reported by the communication device irrespective of whether a second public land mobile network, PLMN, belongs to a first PLMN identity list and/or a current radio access technology, RAT, matches a first RAT)).
Ramachandra teaches that a method performed by a wireless device for configured Minimization of Drive Test, MDT, reporting includes obtaining a MDT configuration. The obtained MDT configuration is for one or more of immediate MDT and logged MDT. The MDT configuration is for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data. Further, the wireless device performs the one or more measurements according to the MDT configuration and provides an MDT report based on the one or more measurements. However Ramachandra differs from the claimed invention in not specifically and clearly describing wherein
signalling, towards a second network node belonging to a second RAT and a second PLMN, an indication comprising a signalling based MDT configuration availability in the communication device irrespective of whether the second PLMN belongs to the first PLMN identity list and/or the second RAT matches the first RAT.
However, in the analogous field of endeavor, OLSSON teaches wherein
signalling, towards a second network node belonging to a second RAT and a second PLMN, an indication comprising a signalling based MDT configuration availability in the communication device irrespective of whether the second PLMN belongs to the first PLMN identity list and/or the second RAT matches the first RA ([0016], e.g. The UE stores unreported MDT measurement information. Thereafter, the UE detects an allowed reporting channel to report MDT measurement information and initiates establishment of a radio link with the radio communications network during which it informs the radio communications network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network.
[0032] A UE may collect logged MDT measurements as long as it is within a configured measurement area like a particular cell that it is camping on from a list of global cell identities (i.e. signalling, towards a second network node belonging to a second RAT and a second PLMN), a list of tracking areas (TAs), location areas (LAs), or registration areas (RAs), etc. If no area scope is configured, UE can log measurements throughout a Public Land Mobile Network (PLMN). Measurement reporting for Logged MDT may be triggered by on-demand mechanism where the UE is asked by the network to send the collected measurement logs via RRC signaling … .. [0038] FIG. 5 , The network node 100 may be a radio network node (some sort of base station or access point) and thus include radio communications circuitry 104. Alternatively or additionally, the network node 100 may be a core network or other network node in which case radio circuitry may not be needed unless that node communicates wirelessly. The data processor 102 connects to one or more network communication interface(s) 106 and to memory 108. The memory 108 includes in addition to program instructions: one or more triggers 112 to request reporting of stored MDT information, e.g., due to UE-RBS connection loss MDT, and MDT data 114 sent from one or more UE (i.e. UEs reporting to multiple networks, including second RAT, second PALM, irrespective of whether the second PLMN belongs to the first PLMN identity list and/or the second RAT matches the first RAT)).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to implement the method of OLSSON within the method of Ramachandra. The motivation to combine references is that the combined system provides that the UE performs MDT measurements for report to the radio communications network as before and detects that no allowed reporting channel to report MDT measurement information exist. The UE stores unreported MDT measurement information. Thereafter, the UE detects an allowed reporting channel to report MDT measurement information and initiates establishment of a radio link with the radio communications network during which it informs the radio communications network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network. The availability indicator may for example be a part of a radio connection setup related message. The stored MDT measurement information may be of the Immediate Report type or of the Logged Report type (See OLSSON [0016]).
Regarding claim 2, Ramachandra in view of OLSSON teaches all the limitations of claim 1. OLSSON further teaches wherein storing the signalling based logged MDT configuration received from the first network node ([0009], e.g. The UE performs minimizing drive test (MDT) measurements for report to the radio communications network. A failure is detected to report MDT measurement information to the radio communications network, and the UE stores unreported MDT measurement information (i.e. storing the signalling based logged MDT configuration received from the first network node)).
The motivation to combine reference of OLSSON within the method of Ramachandra before the effective filing date of the invention is that the new method provides that Although immediate reporting is used for connected mode, there are situations that cannot be handled by immediate reporting including when the UE cannot communicate with the RAN, e.g., the UE's radio link fails. In this situation, the UE typically discards the MDT measurements. But from an operator's perspective, it would still be desirable to receive the MDT measurements at a later time if possible because that MDT measurement information may still be valuable for managing the network (See OLSSON [0007]).
Regarding claim 3, Ramachandra in view of OLSSON teaches all the limitations of claim 1. OLSSON further teaches wherein the indication is signalled when the second PLMN belongs to the first PLMN identity list, and irrespective of whether the first RAT and the second RAT are the same ([0013], e.g. the radio communications network is an LTE-based network. In that case, after receiving a radio resource control (RRC) connection reestablishment request message from the UE, an indication is received in an RRC connection reestablishment complete message from the UE that the RLF message is available. The UE is signaled to transmit the RLF message and at least the unreported MDT measurement information (i.e. ordinary skill can format a message with indication that the second PLMN belongs to the first PLMN identity list, and irrespective of whether the first RAT and the second RAT are the same)).

Regarding claim 4, Ramachandra in view of OLSSON teaches all the limitations of claim 1. OLSSON further teaches wherein the indication is signalled when the first RAT and the second RAT are the same, and irrespective of whether the second PLMN belongs to the first PLMN identity list ([0013], e.g. the radio communications network is an LTE-based network (i.e. when the first RAT and the second RAT are the same). In that case, after receiving a radio resource control (RRC) connection reestablishment request message from the UE (i.e. when the first RAT and the second RAT are the same), an indication is received in an RRC connection reestablishment complete message from the UE that the RLF message is available. The UE is signaled to transmit the RLF message and at least the unreported MDT measurement information (i.e. (i.e. ordinary skill can format a message with indication that first RAT and the second RAT are the same, and irrespective of whether the second PLMN belongs to the first PLMN identity list)).

But from an operator's perspective, it would still be desirable to receive the MDT measurements at a later time if possible because that MDT measurement information may still be valuable for managing the network (See OLSSON [0007]).
Regarding claim 5, Ramachandra in view of OLSSON teaches all the limitations of claim 1. OLSSON further teaches wherein the signalling the indication is performed with the communication device ignoring whether the first RAT and second RAT are the same, and the second PLMN belongs to the first PLMN identity list, respectively ([0010], e.g. the radio communications network is an LTE-based network. In that case, the initiating reestablishment of a radio link step includes transmitting to the radio communications network a radio resource control (RRC) connection reestablishment request message, and transmitting an indication in an RRC connection reestablishment complete message that the RLF message is available (i.e. ordinary skill can format a message with indication that the second PLMN belongs to the first PLMN identity list)).

But from an operator's perspective, it would still be desirable to receive the MDT measurements at a later time if possible because that MDT measurement information may still be valuable for managing the network (See OLSSON [0007]).
Regarding claim 6, Ramachandra in view of OLSSON teaches all the limitations of claim 5. OLSSON further teaches wherein the indication is an indication of the first PLMN and the first RAT ([0010], e.g. the radio communications network is an LTE-based network. In that case, the initiating reestablishment of a radio link step includes transmitting to the radio communications network a radio resource control (RRC) connection reestablishment request message, and transmitting an indication in an RRC connection reestablishment complete message that the RLF message is available (i.e. ordinary skill can format a message with indication of the first PLMN and the first RAT)).

But from an operator's perspective, it would still be desirable to receive the MDT measurements at a later time if possible because that MDT measurement information may still be valuable for managing the network (See OLSSON [0007]).
Regarding claim 7, Ramachandra in view of OLSSON teaches all the limitations of claim 1. Ramachandra further teaches wherein the signalling is performed for a defined period of time after expiration of a timer included in the signalling based logged MDT received from the network node ([0005], e.g. FIG. 1 illustrates an example of MDT logging. For Logged MDT, the UE receives the MDT configurations, including logginginterval (i.e. time period) and loggingduration (i.e. time after expiration), in the RRC message (e.g., LoggedMeasurementConfiguration) from the network. A timer (e.g., timer T330) is started at the UE upon receiving the configurations and set to loggingduration (e.g., 10 min-120 min). The UE performs periodical MDT logging with the interval set to logginginterval (e.g., 1.28 s-61.44 s) when the UE is in RRC_IDLE).
Regarding claim 8, Ramachandra in view of OLSSON teaches all the limitations of claim 1. Ramachandra further teaches wherein transitioning the communication device to a dormant state; and transitioning the communication device to a connected state ([0103], e.g.
rsType configuration: Setting the rsType to SSB will provide the OAM with both connected mode and idle/inactive mode (i.e. dormant state) coverage area analysis possibility. Setting the rsType to CSI-RS will provide the OAM with the opportunity to estimate the impact of a coverage of the connected mode CSI-RSs. [0104] In certain embodiments, the OAM can also provide a dedicated CSI-RS configuration (e.g., CSI-RS-ResourceConfigMobility) to be included in the measurement object associated to the serving cell. This will enable the OAM to test different connected mode coverage options (i.e. transitioning the communication device to a dormant state; and transitioning the communication device to a connected state) compared to SSB based coverages)).
Regarding claim 9, Ramachandra in view of OLSSON teaches all the limitations of claim 8. Ramachandra further teaches wherein while in the dormant state, evaluating a criteria for logged MDT collection based on the received signalling based logged MDT configuration ([0069], e.g. for logged MDT, the following technical advantages may be provided. Certain embodiments may advantageously provide different options for the OAM. The OAM can use these options to collect only the relevant beam information from the UE based on the purpose of collecting those measurements. For example, by logging the best beam index in the idle/inactive mode (i.e. the dormant state, evaluating a criteria for logged MDT ) for the camped cell, the network gets to know the idle mode UE distribution amongst different beams of the camped cell in the coverage area. [0107] rsType configuration: Setting the rsType to SSB will enable the OAM to generate a coverage heat map that is applicable for both connected mode and idle/inactive mode (i.e. in the dormant state, evaluating a criteria for logged MDT collection based on the received signalling based logged MDT configuration)).
Regarding claim 10, Ramachandra teaches a method performed by a network node communicatively connected to a communication device for communicating with a wireless network ([0067], e.g. For example, the present disclosure contemplates various methods to include additional configuration parameters associated to both immediate Minimization of Drive Test (MDT) and logged MDT configurations. The configurations are sent by the Operations, Administration, Management (OAM) to Radio Access Network (RAN) node so that the RAN node can configure the user equipment (UE) with these configurations for MDT purposes), the method comprising:
the indication reported by the communication device irrespective of whether a second public land mobile network, PLMN, belongs to a first PLMN identity list and/or a current radio access technology, RAT, matches a first RAT ([0131] Network 306 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs or PLMN), … and other networks to enable communication between devices). [0045] the control and report associated parameters include: [0051] MDT PLMN List (i.e. the signalling based logged MDT configuration comprising PLMN, identity list. [0196] In certain embodiments, the obtained MDT configuration may comprise an indication of whether or not location information is requested by OAM (i.e. the indication reported by the communication device irrespective of whether a second public land mobile network, PLMN, belongs to a first PLMN identity list and/or a current radio access technology, RAT, matches a first RAT)).
Ramachandra teaches that a method performed by a wireless device for configured Minimization of Drive Test, MDT, reporting includes obtaining a MDT configuration. The obtained MDT configuration is for one or more of immediate MDT and logged MDT. The MDT configuration is for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data. Further, the wireless device performs the one or more measurements according to the MDT configuration and provides an MDT report based on the one or more measurements. However Ramachandra differs from the claimed invention in not specifically and clearly describing wherein
receiving from the communication device, an indication comprising a signalling based minimization of drive test, MDT, configuration availability in the communication device.
However, in the analogous field of endeavor, OLSSON teaches wherein
receiving from the communication device, an indication comprising a signalling based minimization of drive test, MDT, configuration availability in the communication device ([0016], e.g. The UE stores unreported MDT measurement information. Thereafter, the UE detects an allowed reporting channel to report MDT measurement information and initiates establishment of a radio link with the radio communications network during which it informs the radio communications network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network).

The stored MDT measurement information may be of the Immediate Report type or of the Logged Report type (See OLSSON [0016]).
Regarding claim 11, Ramachandra in view of OLSSON teaches all the limitations of claim 10. OLSSON further teaches wherein the indication is reported by the communication device when the second PLMN belongs to the first PLMN identity list, and irrespective of whether the first RAT and a second RAT are the same ([0013], e.g. the radio communications network is an LTE-based network.

Regarding claim 15, Ramachandra in view of OLSSON teaches all the limitations of claim 10. Ramachandra further teaches wherein the indication is reported by the communication device for a defined period of time after expiration of a timer included in a signalling based logged MDT of the communication device received from a network node of a configuring public land mobile network, PLMN, and/or a configuring radio access technology, RAT ([0005], e.g. FIG. 1 illustrates an example of MDT logging. For Logged MDT, the UE receives the MDT configurations, including logginginterval (i.e. time period) and loggingduration (i.e. time after expiration), in the RRC message (e.g., LoggedMeasurementConfiguration) from the network (i.e. public land mobile network, PLMN, and/or a configuring radio access technology, RAT). A timer (e.g., timer T330) is started at the UE upon receiving the configurations and set to loggingduration (e.g., 10 min-120 min). The UE performs periodical MDT logging with the interval set to logginginterval (e.g., 1.28 s-61.44 s) when the UE is in RRC_IDLE).
Regarding claim 16, Ramachandra in view of OLSSON teaches all the limitations of claim 10. Ramachandra further teaches wherein further comprising, responsive to receiving the indication, deciding whether to collect a MDT-related report for the signalling based MDT configuration in the communication device ([0103], e.g. rsType configuration: Setting the rsType to SSB will provide the OAM with both connected mode and idle/inactive mode (i.e. dormant state) coverage area analysis possibility.

Regarding claim 17, Ramachandra in view of OLSSON teaches all the limitations of claim 16. Ramachandra further teaches wherein further comprising, collecting the MDT-related report for the signalling based MDT configuration from the communication device for the received signalling based logged MDT configuration ([0127], e.g. At step 110, the RAN node configures a UE based on the MDT scope either for immediate or logged MDT or both (i.e. received signalling based logged MDT configuration)); and
passing the MDT-related report for the received signalling based MDT configuration to the first PLMN ([0127], e.g. At step 120, the RAN node obtains an MDT report from the UE. At step 130, the RAN node provides a MDT report to OAM (I.e. passing the MDT-related report the first PLMN)).
Regarding claim 20, Ramachandra teaches a communication device for communicating with a wireless network ([0195], e.g. FIG. 16 is a flow chart of a method 1200 in a wireless device (e.g., a UE), in accordance with certain embodiments. The method begins at step 1202, where the wireless device obtains an MDT configuration, wherein the obtained MDT configuration is for one or more of immediate MDT and logged MDT. In certain embodiments, the MDT configuration may be obtained from a RAN node. [0019] Signalling-based MDT: MDT data is collected from one specific UE. The UE that is participating in the MDT data collection is specified as IMEI(SV) or as IMSI. The signalling-based MDT is an enhancement of the signalling-based subscriber and equipment trace. The signalling-based MDT can be either a logged MDT or Immediate MDT, the communication device comprising:
at least one processor; at least one memory connected to the at least one processor and storing program code that is executed by the at least one processor to perform operations ([0160], e.g., In FIG. 8, UE 400 includes processing circuitry 401 that is operatively coupled to input/output interface 405, radio frequency (RF) interface 409, network connection interface 411, memory 415 including random access memory (RAM) 417, read-only memory (ROM) 419, and storage medium 421 (i.e. storing program code that is executed by the at least one processor to perform operations) ), comprising to:
receive a signalling based logged minimization of drive test, MDT, configuration from a first network node belonging to a first radio access technology, RAT ( [0020], e.g. For signaling-based MDT (i.e., UE-specific MDT), the MDT control and configuration parameters are sent by the Network Management to a Mobility Management Entity (MME), which then forwards the parameters to the eNB associated with the specific UE. [0217] FIG. 18 illustrates another method 1400 performed by a wireless device 310 (e.g., a UE) for configured MDT reporting, in accordance with certain embodiments. The method begins at step 1402 when wireless device 310 obtains a MDT configuration. The obtained MDT configuration is for one or more of immediate MDT and logged MDT and is for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data (i.e. receiving signalling based logged minimization of drive test, MDT, configuration));
the signalling based logged MDT configuration comprising a first public land mobile network, PLMN, identity list [0127], e.g. At step 110, the RAN node configures a UE based on the MDT scope either for immediate or logged MDT or both. At step 120, the RAN node obtains an MDT report from the UE. At step 130, the RAN node provides a MDT report to OAM. [0131] Network 306 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs or PLMN), … and other networks to enable communication between devices). [0045] the control and report associated parameters include: [0051] MDT PLMN List (i.e. the signalling based logged MDT configuration comprising PLMN, identity list). [0196] In certain embodiments, the obtained MDT configuration may comprise an indication of whether or not location information is requested by OAM (i.e. the indication reported by the communication device irrespective of whether a second public land mobile network, PLMN, belongs to a first PLMN identity list and/or a current radio access technology, RAT, matches a first RAT)).
Ramachandra teaches that a method performed by a wireless device for configured Minimization of Drive Test, MDT, reporting includes obtaining a MDT configuration. The obtained MDT configuration is for one or more of immediate MDT and logged MDT. The MDT configuration is for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data. Further, the wireless device performs the one or more measurements according to the MDT configuration and provides an MDT report based on the one or more measurements. However Ramachandra differs from the claimed invention in not specifically and clearly describing wherein
signal, towards a second network node belonging to a second RAT and a second PLMN, an indication comprising a signalling based MDT configuration availability in the communication device irrespective of whether the second PLMN belongs to the first PLMN identity list and/or the second RAT matches the first RAT.
However, in the analogous field of endeavor, OLSSON teaches wherein
signal, towards a second network node belonging to a second RAT and a second PLMN, an indication comprising a signalling based MDT configuration availability in the communication device irrespective of whether the second PLMN belongs to the first PLMN identity list and/or the second RAT matches the first RAT ([0016], e.g. The UE stores unreported MDT measurement information. Thereafter, the UE detects an allowed reporting channel to report MDT measurement information and initiates establishment of a radio link with the radio communications network during which it informs the radio communications network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network.
[0032] A UE may collect logged MDT measurements as long as it is within a configured measurement area like a particular cell that it is camping on from a list of global cell identities (i.e. signalling, towards a second network node belonging to a second RAT and a second PLMN), a list of tracking areas (TAs), location areas (LAs), or registration areas (RAs), etc. If no area scope is configured, UE can log measurements throughout a Public Land Mobile Network (PLMN). Measurement reporting for Logged MDT may be triggered by on-demand mechanism where the UE is asked by the network to send the collected measurement logs via RRC signaling … .. [0038] FIG. 5 , The network node 100 may be a radio network node (some sort of base station or access point) and thus include radio communications circuitry 104. Alternatively or additionally, the network node 100 may be a core network or other network node in which case radio circuitry may not be needed unless that node communicates wirelessly. The data processor 102 connects to one or more network communication interface(s) 106 and to memory 108. The memory 108 includes in addition to program instructions: one or more triggers 112 to request reporting of stored MDT information, e.g., due to UE-RBS connection loss MDT, and MDT data 114 sent from one or more UE (i.e. UEs reporting to multiple networks, including second RAT, second PALM, irrespective of whether the second PLMN belongs to the first PLMN identity list and/or the second RAT matches the first RAT)).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to implement the method of OLSSON within the method of Ramachandra. The motivation to combine references is that the combined system provides that the UE performs MDT measurements for report to the radio communications network as before and detects that no allowed reporting channel to report MDT measurement information exist. The UE stores unreported MDT measurement information. Thereafter, the UE detects an allowed reporting channel to report MDT measurement information and initiates establishment of a radio link with the radio communications network during which it informs the radio communications network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network. The availability indicator may for example be a part of a radio connection setup related message. The stored MDT measurement information may be of the Immediate Report type or of the Logged Report type (See OLSSON [0016]).
Regarding claim 21, Ramachandra in view of OLSSON teaches all the limitations of claim 20. OLSSON further teaches wherein the indication is signalled when the second PLMN belongs to the first PLMN identity list, and irrespective of whether the first RAT and the second RAT are the same ([0013], e.g. the radio communications network is an LTE-based network. In that case, after receiving a radio resource control (RRC) connection reestablishment request message from the UE, an indication is received in an RRC connection reestablishment complete message from the UE that the RLF message is available. The UE is signaled to transmit the RLF message and at least the unreported MDT measurement information (i.e. ordinary skill can format a message with indication that the second PLMN belongs to the first PLMN identity list, and irrespective of whether the first RAT and the second RAT are the same)).
The motivation to combine reference of OLSSON within the method of Ramachandra before the effective filing date of the invention is that the new method provides that Although immediate reporting is used for connected mode, there are situations that cannot be handled by immediate reporting including when the UE cannot communicate with the RAN, e.g., the UE's radio link fails. In this situation, the UE typically discards the MDT measurements. But from an operator's perspective, it would still be desirable to receive the MDT measurements at a later time if possible because that MDT measurement information may still be valuable for managing the network (See OLSSON [0007]).
Regarding claim 22, Ramachandra teaches a computer program comprising program code to be executed by processing circuitry of a communication device for communicating with a wireless network, whereby execution of the program code causes the communication device to perform operations ([0160], e.g., In FIG. 8, UE 400 includes processing circuitry 401 that is operatively coupled to input/output interface 405, radio frequency (RF) interface 409, network connection interface 411, memory 415 including random access memory (RAM) 417, read-only memory (ROM) 419, and storage medium 421 (i.e. program code that is executed by the at least one processor to perform operations) ), comprising:

Regarding claim 28, Ramachandra teaches a network node communicatively connected to a communication device for communicating with a wireless network ([0127], e.g. At step 110, the RAN node configures a UE based on the MDT scope either for immediate or logged MDT or both.
