Abstract
A paging group network includes multiple paging groups formed by areas covered by base stations (BSs). The paging group network further includes an anchor paging controller (PC) and a relay PC. The anchor paging controller initiates a page to a mobile station (MS), addresses the paging group in which the MS is located, and stores status information about the MS in a corresponding location register (LR). The relay PC manages the paging groups. A method for updating MS locations is also provided. Thereby, the present invention optimizes the paging and location updating processes, and reduces the complexity of managing the idle mode.
Claims20
A paging group network, comprising:
- an anchor paging controller (PC), adapted to initiate a paging to a mobile station (MS), address a paging group in which the MS is located, and store status information about the MS in a corresponding location register (LR);
- a relay PC, adapted to manage the paging group;
- wherein
- the paging group consists of areas covered by base stations (BSs).
A method for updating mobile station (MS) location, comprising:
- sending, by a serving base station (BS), an MS location updating request to a relay paging controller (PC) controlling the serving BS;
- interacting, by the relay PC, the location updating request with an anchor PC, and assigning a new paging group to the MS;
- sending, by the relay PC, a location updating response carrying the new paging group information to the serving BS;
- and
- modifying, by the anchor PC, the information stored in a location register (LR) according to a result of location updating.
