Coordinating allocations of core network node identifiers in a cellular radio system

摘要

The present invention relates to methods and means for coordinating allocations of core network node identifiers in a cellular radio communication system. A first MSC/VLR in a pool of MSC/VLR's activates (305) the switch from an old traffic allocation plan to a new traffic allocation plan by transmitting a message to all control nodes in the access network. The message includes a subrange of identifiers that are allocated to the first MSC/VLR. The control nodes simultaneously update (306) their mapping of identifiers to all core network nodes in the pool on the basis of the given sub-range of core network node identifiers in the message.
