METHODS FOR EFFICIENT WIRELESS COMMUNICATIONS AND COMMUNICATIONS APPARATUS UTILIZING THE SAME

摘要

A method for efficient wireless communications includes transmitting a tracking area update (TAU) request message by a communications apparatus to a peer device to initiate a TAU procedure; receiving a paging message by the communications apparatus from the peer device after transmitting the TAU request message; and in response to receipt of the paging message, retransmitting the TAU request message by the communications apparatus to the peer device to reinitiate the TAU procedure immediately or transmitting a request message by the communications apparatus to the peer device immediately, without waiting a predetermined time period.

1. A communications apparatus, comprising:
a radio transceiver, transmitting or receiving wireless radio frequency signals to or from a peer device; and a processor, transmitting a tracking area update (TAU) request message to the peer device via the radio transceiver to initiate a TAU procedure, receiving a paging message from the peer device after transmitting the TAU request message, and retransmitting the TAU request message to the peer device to reinitiate the TAU procedure immediately or transmitting a request message to the peer device immediately without waiting a predetermined time period.
