Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 22 and 29 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Publication No. 20110167128 to Raghunathan et al.
Referring to claim 22, Raghunathan et al disclose in Figures 1-5 a method for exposing a duration when a UE is unreachable (loss of connection between BS and UE) caused by a coverage hole (dead spot region) in a coverage area of at least one access node (BS of Figures 1a-1b; each BS has a coverage area as shown by the dotted lines, and within each coverage area is a dead spot region with poor quality of service; Sections 0005-0007, 0007, 0009, 0010, 0033, and 0035) in a telecommunication network (network of Figures 1a-1b), the method comprising:
Obtaining (step 402) an estimated duration of the UE in the coverage hole (Sections 0043-0046 and 0049-0051). A location of a dead spot region within an expected route of UE is identified. UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use. UE estimates the time period during which UE is expected to be in the dead spot region based on the location coordinates of the dead spot region in the coverage area of BS. UE obtains its current location coordinates determined via GPS. UE compares its current location coordinates with the location coordinates of the nearer end of the dead spot region to determine when UE enters the dead spot region. Later, UE compares its current location coordinates with the location coordinates of the farther end of the dead spot region to determine when UE exits the dead spot region. So, UE can estimate the time period during which UE is expected to be in the dead spot region by calculating the difference between the time UE entered the dead spot region and the time UE exited the dead spot region. For example in Section 0050: UE estimates that it will be in the dead spot region from 11:53:04 am to 11:53:47 am.
Transmitting (step 404) the estimated duration of the UE in the coverage hole to at least one network node (one other vehicle) in the telecommunication network (Sections 0043-0046 and 0049-0051). UE broadcasts a signal to at least one other vehicle that is in a vicinity of UE. The signal includes an identification of a time period during which UE is expected to be in the dead spot region, and an identification of the content provider. For example: the signal specifies the time period that UE expects to be in the dead spot region as from 11:53:04 am to 11:53:47 am and also specifies the content provider. Refer to Sections 0005-0016 and 0025-0065.
Referring to claim 29, Raghunathan et al disclose in Figures 1-5 a network entity (UE; the pending application 18/578041 discloses in the specification on page 4 lines 19-21 that the network entity can be a UE) for exposing a duration when a UE is unreachable (loss of connection between BS and UE) caused by a coverage hole (dead spot region) in a coverage area of at least one access node (BS of Figures 1a-1b; each BS has a coverage area as shown by the dotted lines, and within each coverage area is a dead spot region with poor quality of service; Sections 0005-0007, 0007, 0009, 0010, 0033, and 0035) in a telecommunication network (network of Figures 1a-1b), configured to:
Obtain (step 402) an estimated duration of the UE in the coverage hole (Sections 0043-0046 and 0049-0051). A location of a dead spot region within an expected route of UE is identified. UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use. UE estimates the time period during which UE is expected to be in the dead spot region based on the location coordinates of the dead spot region in the coverage area of BS. UE obtains its current location coordinates determined via GPS. UE compares its current location coordinates with the location coordinates of the nearer end of the dead spot region to determine when UE enters the dead spot region. Later, UE compares its current location coordinates with the location coordinates of the farther end of the dead spot region to determine when UE exits the dead spot region. So, UE can estimate the time period during which UE is expected to be in the dead spot region by calculating the difference between the time UE entered the dead spot region and the time UE exited the dead spot region. For example in Section 0050: UE estimates that it will be in the dead spot region from 11:53:04 am to 11:53:47 am.
Transmit (step 404) the estimated duration of the UE in the coverage hole to at least one network node (one other vehicle) in the telecommunication network (Sections 0043-0046 and 0049-0051). UE broadcasts a signal to at least one other vehicle that is in a vicinity of UE. The signal includes an identification of a time period during which UE is expected to be in the dead spot region, and an identification of the content provider. For example: the signal specifies the time period that UE expects to be in the dead spot region as from 11:53:04 am to 11:53:47 am and also specifies the content provider. Refer to Sections 0005-0016 and 0025-0065.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 16, 18-20, 23, and 25-27 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Publication No. 20110167128 to Raghunathan et al in view of U.S. Patent No. 10820263 to Barton et al.
Referring to claim 16, Raghunathan et al disclose in Figures 1-5 a method for estimating a duration when a UE is unreachable (loss of connection between BS and UE) caused by a coverage hole (dead spot region) in a coverage area of at least one access node (BS of Figures 1a-1b; each BS has a coverage area as shown by the dotted lines, and within each coverage area is a dead spot region with poor quality of service; Sections 0005-0007, 0007, 0009, 0010, 0033, and 0035) in a telecommunication network (network of Figures 1a-1b), the method comprising:
Determining that a connection between the UE and the telecommunication network (BS) is lost. Sections 0006, 0011-0013, 0031, 0041, 0043, 0048, 0049, and 0056: UE determines that there is a loss of connection between BS and UE due to increasing distance between UE and BS leading to poor signal quality of service and eventually loss of signal.
Determining (step 402) that the loss of connection is due to the UE entering the coverage hole.
UE has a loss of wireless connectivity with BS when UE is within the dead spot region. A location of a dead spot region within an expected route of UE is identified. UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use. UE obtains its current location coordinates determined via GPS. UE then compares its current location coordinates with the location coordinates of the dead spot region, in order to determine whether or not UE is in the dead spot region.
Estimating (step 402) the duration of the UE in the coverage hole based on (UE estimates the time period during which UE is expected to be in the dead spot region):
… the coverage area and the coverage hole (Figures 1a-1b: each BS has a coverage area as shown by the dotted lines, and within each coverage area is a dead spot region with poor quality of service; Sections 0005-0007, 0007, 0009, 0010, 0033, and 0035). UE estimates the time period during which UE is expected to be in the dead spot region based on the location coordinates of the dead spot region in the coverage area of BS.
And, any one or more of a location information (determined via GPS) or a time information (when UE enters the dead spot region and when UE exits the dead spot region) of the UE in the coverage area (Sections 0043-0046 and 0049-0051). UE obtains its current location coordinates determined via GPS. UE then compares its current location coordinates with the location coordinates of the dead spot region, in order to determine the duration of UE in the dead spot region. UE compares its current location coordinates with the location coordinates of the nearer end of the dead spot region to determine when UE enters the dead spot region. Later, UE compares its current location coordinates with the location coordinates of the farther end of the dead spot region to determine when UE exits the dead spot region. So, UE can estimate the time period during which UE is expected to be in the dead spot region by calculating the difference between the time UE entered the dead spot region and the time UE exited the dead spot region. For example in Section 0050: UE estimates that it will be in the dead spot region from 11:53:04 am to 11:53:47 am. Refer to Sections 0005-0016 and 0025-0065.
Raghunathan et al do not disclose … estimating the duration of the UE in the coverage hole based on: a coverage map comprising the coverage area and the coverage hole, and any one or more of a location information or a time information of the UE in the coverage area. Raghunathan et al only disclose in Sections 0043-0046 and 0049-0051 wherein UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use, but does not disclose a claimed “coverage map” indicating the dead spot region.
Barton et al disclose in Figures 1-12 and Column 2 line 19 to Column 3 line 18, Column 5 lines 15-31, and Column 6 line 57 to Column 7 line 22 wherein the network creates a dark map for WLAN. The dark map comprises a map indicating coverage holes / dead spots in the coverage area of WLAN where WLAN lacks coverage for basic data traffic. UE uses the dark map to identify dead spots in the WLAN. Refer to Column 1 line 53 to Column 10 line 11. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include … estimating the duration of the UE in the coverage hole based on: a coverage map comprising the coverage area and the coverage hole, and any one or more of a location information or a time information of the UE in the coverage area. One would have been motivated to do so to simplify the system by allowing UE to determine dead spot regions using a coverage map, thereby facilitating dead spot region mitigation.
Referring to claim 18, Raghunathan et do not disclose further comprising: creating the coverage map using the signal strength indicators obtained from a plurality of UE in the coverage area over time.
Barton et al disclose in Figures 1-12 and Column 3 lines 39-45, Column 5 lines 50-67, and Column 6 lines 50-65 wherein stations reports their locations along with the strength of signals, such as RSSI, of the APs to a mapping server stations move (claimed “creating the coverage map using the signal strength indicators obtained from a plurality of UE in the coverage area over time”). Mapping server uses the location and signal strength information of the stations to generate a dark map indicating coverage holes / dead spots in the coverage area of WLAN. Other claimed signal strength “indicators” that station reports to mapping server to generate the dark map includes RSNI and SINR. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include further comprising: creating the coverage map using the signal strength indicators obtained from a plurality of UE in the coverage area over time. One would have been motivated to do so so that a coverage map indicating coverage holes can be generated based on signal strength indicators, which indicate when signal strength is low indicative of a coverage hole.
Referring to claim 19, Raghunathan et al disclose in Figures 1-5 further comprising:
Obtaining (step 402) the any one or more of the location information or the time information of the UE in the coverage area over time (location and time of UE when it enters the dead spot region, and location and time of UE when it exits the dead spot region; Sections 0043-0046 and 0049-0051).
Estimating (step 402) the duration of the UE in the coverage hole based on differences in the obtained any one or more of the location information or the time information of the UE in the coverage area over time (Sections 0043-0046 and 0049-0051). A location of a dead spot region within an expected route of UE is identified. UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use. UE estimates the time period during which UE is expected to be in the dead spot region based on the location coordinates of the dead spot region in the coverage area of BS. UE obtains its current location coordinates determined via GPS. UE compares its current location coordinates with the location coordinates of the nearer end of the dead spot region to determine when UE enters the dead spot region. Later, UE compares its current location coordinates with the location coordinates of the farther end of the dead spot region to determine when UE exits the dead spot region. So, UE can estimate the time period during which UE is expected to be in the dead spot region by calculating the difference between the time UE entered the dead spot region and the time UE exited the dead spot region. For example in Section 0050: UE estimates that it will be in the dead spot region from 11:53:04 am to 11:53:47 am. Refer to Sections 0005-0016 and 0025-0065.
Referring to claim 20, Raghunathan et al disclose in Figures 1-5 further comprising:
Determining (step 402), based on the any one or more of the location information or the time information of the UE in the coverage area over time (location and time of UE when it enters the dead spot region, and location and time of UE when it exits the dead spot region; Sections 0043-0046 and 0049-0051), an expected set of any one or more of the location information or the time information of the UE in the coverage hole (expected location and expected time of UE when it enters the dead spot region, and expected location and expected time of UE when it exits the dead spot region) .
Estimating the duration of the UE in the coverage hole based on the determined expected set of any one or more of the location information or the time information. A location of a dead spot region within an expected route of UE is identified (since the method uses the expected route of UE, the location information and time information of UE in the dead spot region is also expected; claimed “expected set of any one or more of the location information or the time information of the UE in the coverage hole”). UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use. UE estimates the time period during which UE is expected to be in the dead spot region (claimed “expected set of any one or more of the location information or the time information of the UE in the coverage hole”) based on the location coordinates of the dead spot region in the coverage area of BS. UE obtains its current location coordinates determined via GPS. UE compares its current location coordinates with the location coordinates of the nearer end of the dead spot region to determine when UE enters the dead spot region. Later, UE compares its current location coordinates with the location coordinates of the farther end of the dead spot region to determine when UE exits the dead spot region. So, UE can estimate the time period during which UE is expected to be in the dead spot region (“expected set of any one or more of the location information or the time information of the UE in the coverage hole”) by calculating the difference between the time UE entered the dead spot region and the time UE exited the dead spot region. For example in Section 0050: UE estimates that it will be in the dead spot region from 11:53:04 am to 11:53:47 am. Sections 0011, 0012, 0028, 0029, 0031, 0035, 0039, 0040, 0042, 0043, 0049, 0050-0052, 0056 and 0058 discloses an expected route of a vehicle, expected time of arrival at a dead spot, and time duration that the vehicle is expected to be in the dead spot which all read on the claimed “expected set of any one or more of the location information or the time information of the UE in the coverage hole”. Refer to Sections 0005-0016 and 0025-0065.
Referring to claim 23, Raghunathan et al disclose in Figures 1-5 a network entity (UE; the pending application 18/578041 discloses in the specification on page 4 lines 19-21 that the network entity can be a UE) arranged for operating in a telecommunication network (network of Figures 1a-1b) and arranged for estimating a duration when a UE is unreachable (loss of connection between BS and UE) caused by a coverage hole (dead spot region) in a coverage area of at least one access node (BS of Figures 1a-1b; each BS has a coverage area as shown by the dotted lines, and within each coverage area is a dead spot region with poor quality of service; Sections 0005-0007, 0007, 0009, 0010, 0033, and 0035) in a telecommunication network, configured to:
Determine that a connection between the UE and the telecommunication network (BS) is lost. Sections 0006, 0011-0013, 0031, 0041, 0043, 0048, 0049, and 0056: UE determines that there is a loss of connection between BS and UE due to increasing distance between UE and BS leading to poor signal quality of service and eventually loss of signal.
Determine (step 402) that the loss of connection is due to the UE entering the coverage hole.
UE has a loss of wireless connectivity with BS when UE is within the dead spot region. A location of a dead spot region within an expected route of UE is identified. UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use. UE obtains its current location coordinates determined via GPS. UE then compares its current location coordinates with the location coordinates of the dead spot region, in order to determine whether or not UE is in the dead spot region.
Estimate (step 404) the duration of the UE in the coverage hole based on (UE estimates the time period during which UE is expected to be in the dead spot region):
… the coverage area and the coverage hole (Figures 1a-1b: each BS has a coverage area as shown by the dotted lines, and within each coverage area is a dead spot region with poor quality of service; Sections 0005-0007, 0007, 0009, 0010, 0033, and 0035). UE estimates the time period during which UE is expected to be in the dead spot region based on the location coordinates of the dead spot region in the coverage area of BS.
And, any one or more of a location information (determined via GPS) or a time information (when UE enters the dead spot region and when UE exits the dead spot region) of the UE in the coverage area (Sections 0043-0046 and 0049-0051). UE obtains its current location coordinates determined via GPS. UE then compares its current location coordinates with the location coordinates of the dead spot region, in order to determine the duration of UE in the dead spot region. UE compares its current location coordinates with the location coordinates of the nearer end of the dead spot region to determine when UE enters the dead spot region. Later, UE compares its current location coordinates with the location coordinates of the farther end of the dead spot region to determine when UE exits the dead spot region. So, UE can estimate the time period during which UE is expected to be in the dead spot region. For example in Section 0050: UE estimates that it will be in the dead spot region from 11:53:04 am to 11:53:47 am. Refer to Sections 0005-0016 and 0025-0065.
Raghunathan et al do not disclose … estimate the duration of the UE in the coverage hole based on: a coverage map comprising the coverage area and the coverage hole, and any one or more of a location information or a time information of the UE in the coverage area. Raghunathan et al only disclose in Sections 0043-0046 and 0049-0051 wherein UE identifies that it is in the dead spot region since UE passed through and sensed the dead spot region previously, and recorded the location coordinates of the dead spot region for future use, but does not disclose a claimed “coverage map” indicating the dead spot region.
Barton et al disclose in Figures 1-12 and Column 2 line 19 to Column 3 line 18, Column 5 lines 15-31, and Column 6 line 57 to Column 7 line 22 wherein the network creates a dark map for WLAN. The dark map comprises a map indicating coverage holes / dead spots in the coverage area of WLAN where WLAN lacks coverage for basic data traffic. UE uses the dark map to identify dead spots in the WLAN. Refer to Column 1 line 53 to Column 10 line 11. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include … estimate the duration of the UE in the coverage hole based on: a coverage map comprising the coverage area and the coverage hole, and any one or more of a location information or a time information of the UE in the coverage area. One would have been motivated to do so to simplify the system by allowing UE to determine dead spot regions using a coverage map, thereby facilitating dead spot region mitigation.

Sections 0005-0007, 0027-0029, 0033, 0034, 0039, 0048, and 0058: within the dead spot region, signal quality is low and signal strength is low. Sections 0043-0046 and 0049-0051: When UE determines that the signal quality is low, that the signal strength is low, or that there is no signal strength, UE identifies that it is in a dead spot region and identifies the location and time of when it is in the dead spot region. UE then records the location coordinates of the dead spot region for future use.

Mapping server uses the location and signal strength information of the stations to generate a dark map indicating coverage holes / dead spots in the coverage area of WLAN. Other claimed signal strength “indicators” that station reports to mapping server to generate the dark map includes RSNI and SINR. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include … estimating the any one or more of the location information or the time information of the UE in the coverage area based on signal strength indicators … One would have been motivated to do so so that a coverage map indicating coverage holes can be generated based on signal strength indicators, which indicate when signal strength is low indicative of a coverage hole.

Biduad et al disclose in Figures 1-17 and Sections 0043, 0051 wherein machine learning software and reference data of landscapes in different weather conditions are used to predict signal strength to maintain maximum connectivity and reduce time spent in wireless dead zones. So, a machine learning algorithm is used to determine UE time spent in dead zones in order to reduce the time spent in the dead zones. Refer to Sections 0038-0151. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include wherein the step of estimating the duration of the UE comprises: estimating, using a machine learning algorithm, the duration of the UE in the coverage hole. One would have been motivated to do so to simplify the estimation of the duration of UE in the coverage hole, since a machine learning algorithm learns patterns to make predictions.
