Patent CA-2359471-C (CA)
Inventor: RASANEN JUHA
IPC: H04L12/56
Filed: 1999-01-25
Granted: 2006-05-16
Abstract: The present invention discloses a method of interworking between different radio access networks (RAN-A, RAN-B). In this method, a radio transceiver device capable of operating with the first radio access network (RAN-A) and the second radio access network (RAN-B) is attached to the first radio access network (RAN-A).      The method comprises the steps of detecting (S11) a service request, accessing information on conditions for the first and the second radio access network (RAN-A, RAN-B) for giving sufficient support for a service requested by the service request, analysing (S12) whether or not the first radio access network (RAN-A) and the second radio access network (RAN-B) meets the conditions, and initiating a handover (S14) of the radio transceiver device (MS) from the first radio access network (RAN-A) to the second radio access network (RAN-B) if the second radio access network (RAN-B) meets the conditions but the first radio access network (RAN-A) does not. Thus, the method according to the present invention serves to support dual mode mobile stations and networks in such a way that the correct radio access which sufficiently supports a requested service is automatically obtained.
