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.

Methods for efficient wireless communications and communications apparatus utilizing the same

A file repair method for Multimedia Broadcast Multicast Service (MBMS) and a UMTS network are disclosed. According to the method, a data structure is established according to a repair request message sent from a user equipment. Each repair block is multicast to the user equipment that requested it by using the original MBMS Bearer Service for file downloading according to the data structure. The present invention does not need any extra traffic and additional control signaling to allow each user equipment to receive required repair blocks.
