METHOD AND APPARATUS FOR CROSS PAGING IN A MULTI-NETWORK COMMUNICATION SYSTEM

摘要

Various embodiments are described which can serve to increase the cross paging call success rate in joint networks. Resource reservation by a requesting network (312) in the context of cross paging is described. In general, such resource reservation may be triggered by the occurrence of any one of a variety of events in conjunction with the requesting network determining that a communication session with an AT (301) is desirable. Examples of triggering events include the following: the AT subscribing for resource reservation as a matter of configuration, the AT having a particular call state and perhaps with regard to particular services, the AT requesting resource reservation (before or after being paged / notified of the requesting network's desire to provide service, the communication session for which the requesting network is requesting the AT is of a particular type, and/or resource reservation is an operational default system operation.
