An improved wireless network provides intersystem handoffs between existing circuit wireless systems and packet systems. A packet wireless system is enhanced to provide translation between circuit and packet call models. A Media Gateway translates bearer traffic between formats used in each system. The Media Gateway, a Media Gateway Control Function, and an associated Call State Control Function, cooperate to emulate the behavior of a circuit wireless system, so that when interoperating with conventional circuit systems, the packet system appears to be another circuit wireless system. Where necessary, the Media Gateway, Media Gateway Control Function, and Call State Control Function further cooperate to emulate the functions of an anchor MSC of a circuit wireless system.
For use in conjunction with a wireless telecommunications network, said network having a portion adapted for packet wireless communications with a terminal and a portion adapted for circuit wireless communications with said terminal, a method for effecting a handover for a call which involves said terminal and another endpoint and which is using one of said portions, such that said call instead uses the other of said portions, comprising the steps of:
For use in conjunction with a wireless telecommunications network, said network having first and second portions each adapted for wireless communications with a terminal, said first portion being adapted to use a type of communications selected from the group of packet and circuit, said second portion being adapted to use a type of communications selected from the group of packet and circuit and different from the communications type of said first portion, a method of effecting a handover for a call which involves said terminal and another endpoint and which is using said first portion, such that said call thereafter uses said second portion, comprising the steps of:
A telecommunications network for wireless service comprising:
