Abstract
A method of routing to a mobile station in a packet switched network arrangement. The method includes forming an initial packet switching route to a mobile station, extending the initial route to form an extended packet switching route, and forming a new packet switching route to replace the extended route dependent on a fall in level of quality of service parameter achieved over the extended route. The initial route is to a first cellular communications gateway and the extended and replacement routes are to a second cellular communications gateway. Also described is corresponding apparatus for routing. Also described is a storage medium storing processor implementable instructions and a signal carrying processor-implementable instructions.
Claims24
A method of routing to a mobile station in a packet switched network arrangement, the method comprising the steps of:
- forming an initial packet switching route to a first cellular communications gateway providing service to a mobile station;
- extending, in response to said first cellular communications gateway handing over service to a second cellular communications gateway to support a handover of the mobile station from a first cell associated with the first cellular communications gateway to a second cell associated with the second communications gateway, said initial packet switching route from the first cellular communications gateway to the second communications gateway to form an extended packet switching route;
- and
- forming, responsive to a level of a quality of service parameter achieved over said extended packet switching route from a source to said second cellular communications gateway, a new packet switching route to said second cellular communications gateway to replace said extended packet switching route.
Apparatus for routing to a mobile station in a packet switched network arrangement, the apparatus comprising:
- means for forming an initial packet switching route to a first cellular communications gateway providing service to a mobile station;
- means for extending, in response to said first cellular communications gateway handing over service to a second cellular communications gateway to support a handover of the mobile station from a first cell associated with the first cellular communications gateway to a second cell associated with the second communications gateway, said initial packet switching route from the first cellular communications gateway to the second communications gateway to form an extended packet switching route;
- and
- means for forming, responsive to a level of a quality of service parameter achieved over said extended packet switching route from a source to said second cellular communications gateway, a new packet switching route to said second cellular communications gateway to replace said extended packet switching route.
