Abstract: A method can be implemented by a user equipment to update RPLMN information. A PLMN identifier is selected from an available PLMN identifier set that includes PLMN identifiers with RPLMN information, HPLMN information, UPLMN information, and OPLMN information separately. A location update request message that carries the PLMN identifier is sent to a mobile switching center. A TMSI reallocation command is acquired from the mobile switching center according to the location update request message. It is determined whether location update acceptance information that is returned by the mobile switching center according to the location update request message is currently acquired. An operation of updating the PLMN identifier to registered public land mobile network RPLMN information is performed when the location update acceptance information is acquired and the operation of updating the PLMN identifier to RPLMN information is skipped when the location update acceptance information is not acquired.

Abstract: A network registration method and apparatus, and a mobile terminal are presented. During re-registration with a network, after receiving a channel allocation rejection message sent by the network, a mobile terminal sorts all available frequency channels according to network resource statuses of frequency channels with which network registration failed before and that are in a low priority list. And then the mobile terminal tries to camp on all the available frequency channels according to an order of the sorting to determine a frequency channel to be camped on. The mobile terminal sends a network registration message to register with the frequency channel to be camped on.
