The purpose of the present document provides the current status of the work "Intra Domain Connection of RAN Nodes to Multiple CN Nodes: Overall System Architecture" within 3GPP TSG RAN WG3.

Currently an RNC can only be connected to one MSC and/or one SGSN. This can bring about inefficient usage of hardware and disproportionate spread of signalling loads across a network.

This Work Item concentrates primarily on a solution where a (standardised) routing function in the RNC enables the connection of multiple MSCs/SGSNs to an RNC. It is hoped that this will bring about a reduction in mobility management signalling and improved efficiency in hardware utilisation.
