Patent ID: 10536839

Abstract:
A system, methods, nodes and computer program for redistributing a registration of a UE (100) from a first MSC (320) to a second MSC (124) is provided. The first MSC (320) and the second MSCs (124) are members of a pool of MSCs (130). The UE (100) is registered in the first MSC (320) and is attached to the first MSC (320) via a packet control node (340, 440) such as MME or SGSN. The first MSC (320) receives an order from an O&M center to redistribute the registrations of UEs (100) in the pool. The first MSC (320) sends a redistribution order to the packet control node (340, 440). The packet control node (340, 440) triggers the UE (100) to perform a routing or tracking area update procedure and triggers a location area update procedure to the second MSC (124), causing the UE (100) to be registered to the second MSC (124).
