Abstract

The present invention provides a method and apparatus for optimizing registration and paging in a group communication system use mobility of the mobile stations to minimize the frequency of registrations performed by the mobile stations as well as the area of paging the mobile stations. When the mobile stations have a low mobility status, the base station reduces the area of paging the mobile stations so that the paging channel load is reduced.

Description

technical field [0001] The present invention relates to point-to-multipoint communication systems. More particularly, the present invention relates to methods and apparatus for optimizing registration frequencies and paging areas in a wireless group communication network. Background technique [0002] In wireless communication systems, registration is the process used by a mobile station to inform the base station of its location, status, identity, slot cycle and other characteristics. The mobile station informs the base station of its location and status, so that the base station can efficiently page the mobile station when establishing a mobile station terminal call. On the other hand, paging a mobile station includes the act of finding the mobile station when a call is to be delivered to the mobile station. To save system capacity, reduce service costs, and extend battery life, it is desirable to minimize registration and paging channel loads. However, actions to minim...
