Abstract:

In a mobile communications system, when traffic conditions deteriorate, a priority scheme allows predetermined types of calls to be differently serviced, so that higher priority subscribers obtain the maximum possible bandwidth or other resources. Conversely, when traffic conditions improve, additional bandwidth may be allocated to existing subscribers or additional subscribers/types of service may be permitted to maximize bandwidth utilization. Further, when a mobile call disconnects, the disclosed system saves the context at which the call was disconnected and attempts to restore pre-disconnection status to the connection, if the subscriber wishes to reconnect within a prescribed time limit. In an embodiment, the instant disclosure preserves the call context by writing call-related data in a data store on network side or on mobile terminal side or on both sides. On the network side, call related in formation may be stored in a file, which can also identify the mobile terminal. On the mobile terminal side, the call related information is stored in the form of a cookie or other store and preserved in nonvolatile memory. By thus preserving the call information (context as well as other information) when the subscriber reestablishes connection with the mobile communication network within the prescribed time limit, the subscriber may be prompted to continue with his prior activity, and if he chooses so, he can be reconnected to perform the same task as before.
