Abstract
A method for selecting a public land mobile network to serve a mobile station includes the step of receiving at the mobile station a list of data associated with networks neighboring the PLMN currently serving the mobile station. A new PLMN to serve the mobile station is selected based upon the list of data, and the mobile station changes to the selected new PLMN.
Claims30
A method for selecting a public land mobile network to serve a mobile station, comprising the steps of:
- receiving at the mobile station a list of data associated with networks neighboring a PLMN currently serving the mobile station;
- selecting a new PLMN to serve the mobile station from the PLMNs neighboring the PLMN currently serving the mobile station based upon the list of data;
- and
- changing the mobile station to the selected new PLMN.
A method for selecting a PLMN to serve a mobile station comprising the steps of:
- transmitting from a base station associated with a serving PLMN to the mobile station a list of neighboring PLMNs;
- selecting a new PLMN from the list of neighboring PLMNs as a new PLMN to serve the mobile station;
- and
- changing the mobile station to the new PLMN.
The method for selecting a preferred PLMN to serve a mobile station, comprising the steps of:
- transmitting from a base station associated with a serving PLMN to the mobile station at least one mobile country code associated with a neighboring network;
- selecting the preferred PLMN as a new serving PLMN if the at least one mobile country code is associated with the preferred PLMN;
- scanning for the preferred PLMN;
- and
- changing the mobile station to the preferred PLMN.
A mobile terminal comprising:
- circuitry for wirelessly connecting the mobile terminal to a serving PLMN network;
- a neighbor list containing data received from the serving PLMN enabling selection of a PLMN neighboring the serving PLMN as a new serving PLMN;
- and
- control logic for selecting the new serving PLMN responsive to the data of the neighbor list.
