First Claim
Patent Images
1. A method for system interoperability in communication networks, comprising:
- establishing context information related to activity of a mobile station within a first communication system, wherein said context information can be used in a second communication system but is incompatible with contexts within the first communication system;
keeping said context information up to date;
keeping said context information on hold while the mobile station is connected to the first communication system; and
puting to use said context information when the mobile station switches to the second communication system, wherein said second communication system is not based on the same context as the first communication system.

Abstract
In a method and apparatus for providing system interoperability in wireless communications an IP based client-server application maintains a proper set of PDP contexts while a mobile is connected via an IP based system. The application client resides in the mobile and the server resides within the network at a common anchor point between the IP based system and a PDP contexts based system. The PDP contexts are kept up to date but on hold until a handover occurs for the mobile from the IP based system to the PDP contexts based system.

16. A mobile station operable in a wireless communication system, the mobile station comprising:
-
a processor, configured for establishing context information related to activity of a mobile station within a first communication system, wherein said first communication system is not a context based system;
keeping said context information up to date;
keeping said context information on hold while the mobile station is connected to the first communication system; and
puting to use said context information when the mobile station switches to a second communication system, wherein said second communication system is a context based communication system; and
a memory coupled to the processor for storing data. - View Dependent Claims (17, 18, 19, 20)
