METHODS FOR EFFICIENT WIRELESS COMMUNICATIONS AND COMMUNICATIONS APPARATUS UTILIZING THE SAME

摘要

A method for efficient wireless communications performed by a communications apparatus includes determining a cell according to a low priority list; and performing an attach procedure to try to attach to the cell for establishing an emergency call through the cell. The low priority list comprises information regarding a public land mobile network (PLMN) identity (ID), tracking area (TA) code, a cell ID and/or a closed subscriber group (CSG) ID of at least one attempted cell through which the communications apparatus has attempted but failed to establish an emergency call.

主权项

1. A communications apparatus, comprising:
a radio transceiver, transmitting or receiving wireless radio frequency signals; and a processor, determining a cell according to a low priority list and performing an attach procedure via the radio transceiver to try to attach to the cell for establishing an emergency call through the cell, wherein the low priority list comprises information regarding a public land mobile network (PLMN) identity (ID), a tracking area (TA) code, a cell ID and/or a closed subscriber group (CSG) ID of at least one attempted cell through which the processor has attempted but failed to establish an emergency call.
