Coordination of subscriber register entries

Abstract

A system, method, node and computer program for coordinating subscriber registration entries () of a subscriber in two subscriber location registers, a subscriber location register in a MSC (), and a subscriber location register in a packet control node (), is presented. The subscriber is registered into the subscriber location register in the MSC () via the packet control node (). The method comprises determining, by one of the two subscriber location registers, a trigger condition for modifying a subscriber registration entry () in that one subscriber location register. If the trigger condition is met, modifying the subscriber registration entry () in that one subscriber location register and sending a notification of this subscriber registration entry () modification to the other subscriber location register. The method further comprises to receive, by the other subscriber location register, the notification of this subscriber registration entry () modification and to modify the subscriber registration entry () in the other subscriber location register.
