1. A method for system interoperability in communication networks, comprising:
- monitoring activity including a set of services currently being used by a mobile station within a first communication system;
establishing context information related to the monitored activity of the mobile station within the 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;
periodically transmitting said on hold context information to the mobile station; and
putting 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 for communication in a wireless communication system, the mobile station comprising:
-
a processor, configured for establishing context information related to a current activity, including a set of services currently being used, of the 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 by receiving periodic transmissions from the first communication system;
keeping said context information on hold while the mobile station is connected to the first communication system; and
putting 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; anda memory coupled to the processor for storing data. - View Dependent Claims (17, 18, 19, 20)
