Abstract
The invention proposes a system and method for providing a connection in a communication network which comprises several network elements and is adapted to route a connection via a first network element such as a radio network controller and one or more of alternatively selectable second network elements such as serving nodes. The network comprises a network element which stores a list of selectable second network elements. The list is accessed using an identifier identifying a routing or location area or a desired second network element. The list can be stored in a DNS server which returns to an inquiring network element such as a radio network controller, e.g. IP addresses of serving nodes capable of serving a routing or location area of a connection originating or terminating network element. The connection originating or terminating network element may also be adapted to send an identifier identifying a specific network element such as an SGSN to which it desires to be connected.
