1. A method comprising:
- receiving a deregistration request from a mobile station;
determining whether or not to accept the deregistration request with context retention;
storing, in response to the deregistration request from the mobile station, a context associated with the mobile station and a frame-offset with respect to a frame in which the deregistration request is transmitted, wherein the context and frame-offset is stored while the mobile station is registered with another radio access technology; and
sending a deregistration command message to the mobile station if the deregistration request with context retention is allowed, wherein the deregistration command message indicates to the mobile station that the context and the frame-offset is stored successfully.

13. A network system comprising:
-
a processor; a memory coupled to the processor; and a communication device, coupled to the processor to receive a deregistration request from a mobile station; determine whether or not to accept the deregistration request with context retention; store, in response to the deregistration request from the mobile station, a context associated with the mobile station and a frame-offset with respect to a frame in which the deregistration request is transmitted, wherein the context and frame-offset is to be stored while the mobile station is registered with another radio access technology; propagate the context and frame-offset to be stored by a paging controller; receive an acknowledgement from the paging controller that the context and the frame-offset has been successfully stored; and send a deregistration command message to the mobile station if the deregistration request with context retention is allowed, wherein the deregistration command message indicates to the mobile station that the context of the mobile station and the frame offset is stored successfully. - View Dependent Claims (14)
