NETWORK ELEMENT, INTEGRATED CIRCUIT, CELLULAR COMMUNICATION SYSTEM AND METHOD THEREFOR

摘要

A network element comprises a signal processor supporting communications between a subscriber unit (UE) and a core network (CN). The signal processor is arranged to: receive a first update request message (location or routing area) from the subscriber unit; forward the first update request message to the core network; receive from the CN a first update accept (or response) message; store at least a part of the accept message content; forward the first update response message to the subscriber unit; receive a second update request from the subscriber unit; create a second update accept (or response) message using the at least part of the stored content; and respond to the subscriber unit second update accept (or response) message direct.

主权项

1. A network element for supporting communications between a subscriber unit and a core network, wherein the network element comprises:
a transceiver, memory and a signal processor operably coupled to the transceiver and memory, wherein the signal processor is arranged to: receive a first update request message from the subscriber unit; forward the first update request message to the core network; receive from the core network a first update response message; extract and store in memory at least a part of the first update response message content; forward the first update response message to the subscriber unit; receive at least one second update request from the subscriber unit; create at least one second update response message using the at least part of the stored content; and respond directly to the subscriber unit with the at least one second update response message.
