Radio communication system, method and arrangement for use in a radio communication system

A method for use in a radio communication system of the type which comprises a first access network arranged to operate according to a first Radio Access Technology capable of providing a communication service over a first communication path through the first access network, a second access network arranged to operate according to a second Radio Access Technology capable of providing the communication service over a second communication path through the second access network and wherein the first and second Radio Access Technologies are different, and a user device which is connectable to said first access network over the first communication path and to said second access network over the second communication path, wherein said method comprises:

• identifying said user device, when seeking access to said second access network, through a user device identifier for said user device,
• wherein said user device is identified based on a user device identifier provided by the user device, and
• wherein said user device identifier is associated with said first access network;
• providing information about a context of said user device in said first access network based on said user device identifier;
• generating an access selection decision for the access sought by the user device to the second access network based on the provided context information;
• and
• causing execution of said access selection decision.

A node for use with a first access network arranged to operate according to a first Radio Access Technology capable of providing a communication service over a first communication path to a user device through the first access network and a second access network arranged to operate according to a second Radio Access Technology capable of providing the communication service over a second communication path to the user device through the second access network, wherein the user device is connectable to said first access network and to said second access network and wherein the first and second Radio Access Technologies are different, wherein said node comprises:

• means for obtaining a user device identifier identifying the user device, when seeking access to said second access network, wherein said user device identifier is associated with said first access network, wherein the user device identifier is provided by the user device;
• means for obtaining information about a context of said user device in said first access network based on said user device identifier;
• means for generating an access selection decision for the access sought by the user device to the second access network based on the provided context information;
• and
• means for causing said access selection decision to be executed.

The node according to claim, 28, wherein the means for generating the access selection decision comprises means for maintaining connection for the user device with the first access network including,

• means for identifying the communication service provided initially to the user device through the first access network,
• means for analyzing the provided context information of the user device, and
• means for selecting the first access network to provide the communication service to the user device based on the provided context information of the user device,
• wherein the means for causing the access selection decision to be executed comprises means for continuing to provide the communication service through the first access network.
