Interworking between radio access networks
First Claim
1. A method, comprising:
- detecting a request for specific service for a radio transceiver device, wherein said radio transceiver device is configured to operate with a first radio access network and a second radio access network and the radio transceiver device is attached to said first radio access network;
accessing information on conditions for the first radio access network and the second radio access network to provide sufficient support for a specific service requested by said request for the specific service;
analyzing whether said first radio access network and said second radio access network meet said conditions; and
initiating a handover from said first radio access network to said second radio access network when the conditions are met by the second radio access network, but not met by the first radio access network,wherein information about service availability in the second radio access network are sent from the second radio access network to the radio transceiver device during establishment of a call.

Abstract
The present invention discloses a method of interworking between different radio access networks. In this method, a radio transceiver device 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, accessing information on conditions for the first and the second radio access network for giving sufficient support for a service requested by the service request, analysing whether or not the first radio access network and the second radio access network meets the conditions, and initiating a handover of the radio transceiver device from the first radio access network to the second radio access network if the second radio access network meets the conditions but the first radio access network 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.
