Abstract
Embodiments of the present invention disclose a public land mobile network PLMN selection method, including: when a mobile terminal is about to hand over from a first cell to a neighboring second cell, selecting, by the mobile terminal, a preferred PLMN after handover to the second cell; and sending, by the mobile terminal, identifier ID information of the preferred PLMN to a base station controller to which the first cell belongs. The embodiments of the present invention further disclose a mobile terminal, a base station controller, and a core network device. By applying the present invention, the PLMN to which the mobile terminal intends to hand over can be determined properly.
Claims6
A PLMN selection method, comprising:
- receiving, by a core network device, a handover request from a base station controller, wherein the handover request is used to request handover of a mobile terminal from a first cell to a neighboring second cell, wherein the mobile terminal is in a cell to which the base station controller belongs;
- selecting, by the core network device, according to subscription attribute information of the mobile terminal, a preferred PLMN of the mobile terminal;
- and
- performing, by the core network device, a handover process according to the handover request, and sending ID information of the preferred PLMN of the mobile terminal to a base station controller to which the second cell belongs.
A computer program product comprising a readable storage medium storing program code thereon for use by a core network device, the program code comprising:
- instructions for receiving a handover request from a base station controller, wherein the handover request is used to request handover of a mobile terminal from a first cell to a neighboring second cell, wherein the mobile terminal is in a cell to which the base station controller belongs;
- instructions for selecting, according to subscription attribute information of the mobile terminal, a preferred PLMN of the mobile terminal;
- and
- instructions for performing a handover process according to the handover request received by the receiving unit, and send the ID information of the preferred PLMN of the mobile terminal to a base station controller to which the second cell belongs.
