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

Abstract: A method for operating a network entity is provided in a wireless communications network. The method includes receiving a message comprising a temporary identifier of a mobile entity. The temporary identifier is used to temporarily identify the mobile entity. The temporary identifier includes an identifier of variable length which is used to identify a core network control entity which controls the mobile entity when connected to the network. The method determines a length indicator present in the temporary identifier, where the length indicator indicates a length of the identifier in the temporary identifier. The method determines the identifier in the temporary identifier based on the length indicator and the core network control entity based on the identifier, and transmits the received message to the determined core network control entity.

Abstract: A system, method, node and computer program for coordinating subscriber registration entries (150) of a subscriber in two subscriber location registers, a subscriber location register in a MSC (220), and a subscriber location register in a packet control node (200), is presented. The subscriber is registered into the subscriber location register in the MSC (220) via the packet control node (200). The method comprises determining, by one of the two subscriber location registers, a trigger condition for modifying a subscriber registration entry (150) in that one subscriber location register. If the trigger condition is met, modifying the subscriber registration entry (150) in that one subscriber location register and sending a notification of this subscriber registration entry (150) modification to the other subscriber location register.

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).

Abstract: A system, methods, node, and non-transitory computer readable medium storing a computer program, for deregistration of a user equipment from the source control node are described. The user equipment is registered in the source control node and in a subscriber database while roaming from the source control node to a target control node. The method in the source control node comprises receiving an identification request message from the target control node, the identification request requesting identification and security related information. The method in the source control node further comprises, as triggered by the identification request message, starting a time supervision supervising reception of a cancel location message from the subscriber database. When the time supervision expires, the user equipment is deregistered from the source control node.
