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 1-2, 5, 9-10, 12, 15-16 and 19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ishii (US 2019/0261261).
Regarding claim 1, Ishii describes a method comprising:
receiving a policy for filtration of resources (fig. 2 & para. 46-49, terminal 26 receives access control information 64 of network resources (policy for filtration of resources, comprising barring parameters, fig. 2-1. See also fig. 4-5 step 4-5-2),
applying the policy to a first path comprising a first network and a second path comprising a second network (para. 49, terminal 26-5 storing such received access control in formation/configuration in the access control procedure for access determination (applying). In fig. 1-5 & 2-5 & para. 110 + 121-122, terminal is connected to 2 networks. If procedure results in access attempt to first network being barred, terminal initiates inter-system mode change procedure to register to the other network, fig. 4-3. See also fig. 4-5 steps 4-5-3 & 4-5-4);
receiving, from a user device and based on the first path, a first request for a first resource, and determining, based on the first resource and the application of the policy, to impede access to the first resource (fig. 4-1, 4-2, 4-3, 4-4 in view of fig. 1-5 & 2-5 & para. 110 + 121-122, upon receiving access attempt (first request to first resource) to the first network (first resource) as currently registered network (first path), if procedure results in first network being barred (impeded access), terminal will initiate inter-system mode change procedure to register & access the other network (second path to second resource). See also fig. 4-5 steps 4-5-3 & 4-5-4).
Regarding claim 9, Ishii describes a method comprising:
receiving a policy for filtration of resources (fig. 2 & para. 46-49, terminal 26 receives access control information 64 of network resources (policy for filtration of resources, comprising barring parameters, fig. 2-1. See also fig. 4-5 step 4-5-2),
applying the policy to a first path comprising a first network and a second path comprising a second network (para. 49, terminal 26-5 storing such received access control in formation/configuration in the access control procedure for access determination (applying). In fig. 1-5 & 2-5 & para. 110 + 121-122, terminal is connected to 2 networks. If procedure results in access attempt to first network being barred, terminal initiates inter-system mode change procedure to register to the other network, fig. 4-1, 4-2, 4-3, 4-4. See also fig. 4-5 steps 4-5-3 & 4-5-4);
sending, based on the first path, a first request for a first resource; and determining, based on the first resource and the application of the policy, to impede access to the first resource (fig. 4-1, 4-2, 4-3, 4-4 in view of fig. 1-5 & 2-5 & para. 110 + 121-122, upon receiving [sent] access attempt (first request to first resource) to the first network (first resource) as currently registered network (first path), if procedure results in first network being barred (impeded access), terminal will initiate inter-system mode change procedure to register & access the other network (second path to second resource). See also fig. 4-5 steps 4-5-3 & 4-5-4).
Regarding claim 15, Ishii describes a method comprising:
receiving a first policy for filtration of resources; and receiving a second policy for the filtration of resources (fig. 4-5 step 4-5-2 & para. 126 or 128, receiving the first and second access control information for the respective first & second network (first & second policies for filtration of resources)),
applying the first policy to a first path comprising a first network and applying the second policy to a second path comprising a second network (para. 49, terminal 26-5 storing such received access control in formation/configuration in the access control procedure for access determination (applying). In fig. 1-5 & 2-5 & para. 110 + 121-122, terminal is connected to 2 networks. If procedure results in access attempt to first network being barred, terminal initiates inter-system mode change procedure to register to the other network, fig. 4-1, 4-2, 4-3, 4-4. See also fig. 4-5 steps 4-5-3 & 4-5-4);
receiving, based on the first path and the second path, a first request for a first resource, and determining, based on the first resource and the application of the first policy and the application of the second policy, to impede access to the first resource (Nayak, fig. 2 step 208 & para. 39, UE receives the determined barring factor for the service (first resource) corresponding to the cell a barring duration, or whether the particular cell is barred or not, para. 40. See also para. 31) (fig. 4-1, 4-2, 4-3, 4-4 in view of fig. 1-5 & 2-5 & para. 110 + 121-122, upon receiving access attempt (first request to first resource) to the first network (first resource) as currently registered network (first path), if procedure’s first access control information (application of the first policy) indicates first network (first resource) being barred, terminal will initiate inter-system mode change procedure to register & access the other network (second path to second resource). See also fig. 4-5 steps 4-5-3 & 4-5-4).
Regarding claims 2 and 16, Ishii describe:
wherein the policy is applied to a connection comprising a first subflow over the first path and a second subflow over the second path (fig. 4-5 in view of para. 58, the first & second access control information (policy) is applied to access/connection attempt for voice/video data over first network (first subflow over first path) and attempt for voice/video data over second network (second subflow over second path).
Regarding claims 5, 10 and 19, Ishii describes:
wherein the first network comprises a first node and the second network comprises a second node, and the first path comprises the second node (fig. 1-5 or 2-5, first network as EPC 21-5 comprising MME 98 (first node) and second network as 5GCN 21-5-5GCN comprising AMF 100 + eNB-5G (second node), where first path as AMF + eNB-5G (second node)).
Regarding claims 12, Ishii describes:
wherein the first path comprises the second node and the second path comprises the second node (fig. 1-5 or 2-5, eNB-5G (second node) is used by the terminal/UE to communicate with EPC network 21-5-EPC (first path) and 5GN (second path)).
Claims 3-4 and 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over Ishii as applied to claim 2 above, and further in view of Lee (US 2007/0286125).
Regarding claims 3 and 17, Ishii describes switching first & second subflows (Nayak, para. 33), but fails to further explicitly describe:
assembling the first request based on a data sequence mapping and a first subflow sequence number of the first subflow and a second subflow sequence number of the second subflow.
Lee also describes conventional handover procedures (fig. 3 & para. 14), further describing:
