Method, network node and system for selecting network nodes
First Claim
1. A method for identifying and selecting network nodes in a telecommunication system comprising a core network comprising at least a plurality of core network nodes, a plurality of radio network access servers belonging to one or more pool-areas, the radio network access servers being connected to one or more core network nodes, one or more IP base stations each of which being connected to one or more radio network access servers and a plurality of mobile terminals connected to one or more IP base stations, wherein the method comprises the step of:
- selecting a core network node and a radio network access server in the pool-area in connection with the core network node at the time of setting up a signaling connection to the core network;
sending address information of the selected core network node to be used in the signaling connection set-up to the selected radio network access server; and
setting up the signaling connection to the selected core network.

Abstract
The present invention describes a method, system, IP base station and radio network access server for identifying and selecting network nodes in a telecommunication system comprising a core network comprising a plurality of core network nodes, a plurality of radio network access servers belonging to one or more pool-areas and one or more IP base stations each of which being connected to one or more radio network access servers and a plurality of mobile terminals connected to one or more IP base stations. In the method, a core network node and a radio network access server in the pool-area is selected in connection with the core network node at the time of setting up a signaling connection to the core network and address information of the selected core network node to be used in the signaling connection set-up is sent to the selected radio network access server.
