INCLUDING A HASHED SERVICE IDENTIFIER IN A PAGING MESSAGE FOR A SERVICE GROUP CALL

摘要

A service provided to wireless stations (1) through a telecommunication network (2) is identified by a unique service identifier stored in the telecommunication network and in at least one subscriber station among the wireless stations. The method comprises the steps of: determining a paging identifier in the telecommunication network and at said subscriber station, by applying a hash function to a data string including at least part of the unique service identifier; associating said subscriber station with the determined paging identifier; and prior to transmitting information pertaining to the service over a broadcast channel, transmitting a paging message incorporating said paging identifier to the wireless stations.
