Method and apparatus for cross paging a multi network communication system
First Claim
1. A method to facilitate cross-paging in a multi-network communication system, the method comprising:
- an access terminal establishing a first call in a serving network;
the access terminal receiving a page from a target network, the page requesting to establish a second call in the target network, wherein the second call is different from the first callin response to receiving the page and before terminating the first call, the access terminal requesting resource reservation at the target network for the second call; and
receiving a page from the serving network indicating that at least one communication resource has been reserved at the target network for the second call.

Abstract
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.

2. A method for cross-paging in a multi-network communication system, the method comprising:
-
requesting, by a target network via a serving network, establishment of a second communication service with an access terminal (AT), wherein the AT is currently engaged in a first communication service in the serving network; in response to requesting, the target network receiving from the serving network information indicating a present call state of the AT in the serving network; in response to receiving, establishing, by the target network, a connection with the AT to support the second communication service; and sending, by the target network to the serving network, an indication that at least one communication resource has been reserved in anticipation of providing the second communication service to the AT. - View Dependent Claims (3, 4, 5, 6, 7)

8. A method for cross-paging in a multi-network communication system, the method comprising:
-
providing a first communication service to an access terminal (AT) by a serving network; receiving, by the serving network, a page from a target network requesting to provide a second communication service to the AT, while the AT is in the first communication service with the serving network; in response to receiving the page from the target network, the serving network sending information indicating a present call state of the AT in the serving network; receiving an indication, by the serving network from the target network, that at least one communication resource has been reserved in anticipation of providing the second communication service to the AT; and in response to receiving an indication from the target network, the service network paging the access terminal for the communication service to be provided by the target network. - View Dependent Claims (9, 10, 11)

12. An access terminal (AT) comprising:
-
a transceiver; a processing unit, communicatively coupled to the transceiver, the process unit adapted to establish a first call in a serving network; receive a page from a target network, the page requesting to establish a second call in the target network; in response to receiving the page and before terminating the first call, the access terminal requesting resource reservation at the target network for the second call; and receive a page from the serving network indicating that at least one communication resource has been reserved at the target network for the second call.
