Method and user equipment with dual RF transceivers to perform PLMN list generation or PLMN search
Abstract:
Techniques for efficiently performing public land mobile network (PLMN) list generation or PLMN search on user equipment for use in a mobile communication system are described. The user equipment is operating in a plurality of supported modes and each supported mode includes a plurality of frequency bands. The user equipment includes an antenna, two RF transceivers and a processor. The RF transceivers are coupled to the antenna for operating in the operating frequency bands via the antenna. The processor coupled to the RF transceivers receives a request requesting PLMN list generation or PLMN search, determines whether both or either of the RF transceivers are available for handling the PLMN list generation or PLMN search, respectively directs the RF transceivers to generate a PLMN list or perform a search for at least one selected operating frequency band according to the request and a dispatch rule, and provides a corresponding execution result.
