a memory storing instructions executable by the processor (operations of the network entity may be realized by providing the memory device 830 storing the corresponding program code, Kweon: [0252]); and
a transceiver coupled with the processor (transceiver 810 may transmit and receive signals to and from other network entities. The controller 820 and the transceiver 810 may be electrically connected, Kweon: [0252]),
wherein the processor is configured to perform the method of claim 15 (The controller 820 may control the network entity to perform any one operation, Kweon: [0252]).
Regarding claim 49, Kweon in view of 3GPP teaches all the claimed limitations as set forth in the rejection of claim 21 above.
Kweon further discloses:
A third network element, comprising (a policy control function (PCF) 150 may be a network function. network entity according to an embodiment of the disclosure may include a transceiver 810 and a controller 820 for controlling overall operations of the network entity. The transceiver 810 may include a transmitter and a receiver. The network entity may include a storage 830, Kweon: Fig.5, Fig.8, [0055], [0249]-[0252]):
a processor (the controller 820 may be a circuit, an application-specific circuit, or at least one processor, Kweon: [0252]);
a memory storing instructions executable by the processor (operations of the network entity may be realized by providing the memory device 830 storing the corresponding program code, Kweon: [0252]); and
a transceiver coupled with the processor (transceiver 810 may transmit and receive signals to and from other network entities. The controller 820 and the transceiver 810 may be electrically connected, Kweon: [0252]),
wherein the processor is configured to perform the method of claim 21 (The controller 820 may control the network entity to perform any one operation, Kweon: [0252]).
