Interworking between radio access networks
First Claim
1. A method, comprising:
- detecting a service request, wherein said service request is received from a network side;
accessing information on conditions for a first and a second radio access network for giving sufficient support for a service requested by said service request, analysing whether or not said first radio access network and said second radio access network meets said conditions; and
initiating a handover of a radio transceiver device from said first radio access network to said second radio access network if the second radio access network meets the conditions but the first radio access network does not.

Abstract
The present invention discloses a method of interworking between different radio access networks. A radio transceiver device is capable of operating with the first radio access network and the second radio access network is attached to the first radio access network. The method comprises the steps of detecting a service request is requested. Information is accessed on conditions for the first and the second radio access network for giving sufficient support for a service requested by the service request. It is analyzed whether or not the first radio access network and the second radio access network meets the conditions, and a handover of the radio transceiver device from the first radio access network to the second radio access network is initiated if the second radio access network meets the conditions but the first radio access network does not. Thus, 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.

18. A network interworking device, comprising:
-
a detecting unit configured to detect a service request, wherein said service request is received from a network side, an analyzing unit responsive to said detecting unit and wherein the analyzing unit is configured to, access information on conditions for a first and a second radio access networks for giving sufficient support for a service requested by said service request, and analyse whether or not said first radio access network and said second radio access network meet the conditions, and initiating unit responsive to said analysing unit, the initiating being configured to initiate a handover of said radio transceiver device from said first radio access network to said second radio access network if the respective conditions are not met by said first radio access network but by said second radio access network. - View Dependent Claims (19, 20, 21)
