Radio Communication System, Method and Arrangement for Use in a Radio Communication System

摘要

A system includes a first access network arranged to operate according to a first Radio Access Technology, a second access network arranged to operate according to a second Radio Access Technology, and a user device which is connectable to the first access network and to the second access network. The system also includes an authentication node arranged to identify the user device, when seeking access to the second access network, through a user device identifier for the user device, wherein the user device identifier is associated with the first access network. A query node provides information about a context of the user device in the first access network based on the user device identifier. An access selection node generates an access selection decision for the access sought by the user device to the second access network based on the provided context, and the access selection decision is then executed.

主权项

1. A method of operating a node of a first Radio Access Network (RAN) of a first Radio Access Technology (RAT), the method comprising:
receiving an access attempt at the node from a user device, wherein the access attempt includes a user device identifier associated with a second Radio Access Network (RAN) of a second Radio Access Technology different than the first Radio Access Technology; transmitting a query from the node to the second Radio Access Network, wherein the query includes an identification of the user device based on the user device identifier received from the user device; and after transmitting the query, providing a communication service for the user device through the node of the first Radio Access Network.
