Abstract: A method is disclosed for paging of a terminal having a first subscriber identity (IMSI1) attachable to a first mobile communication network (101) and a second subscriber identity (IMSI2) attachable to a second mobile communication network (201). The method is performed in a controller node (213; 600) of the second mobile communication network and involves registering (310, 410) the terminal's second subscriber identity (IMSI2) as attached to the second mobile communication network (201), followed by registering (320, 420) an auxiliary paging address (422) for the terminal's second subscriber identity. Then, a need to page the terminal's second subscriber identity is determined (330), and the terminal's second subscriber identity is paged (340). The paging involves sending (240) an auxiliary paging message (442) to the registered auxiliary paging address, and the auxiliary paging message is adapted for delivery to the terminal's first subscriber identity (IMSI1).

Abstract: The present invention facilitates control over inter-system handover between different types of radio access technologies. Assuming a radio connection has been established between a first mobile radio communications system and a user equipment (UE) using an anchor node, a request is made for handover of the UE connection to a second mobile radio communications system that includes a non-anchor node. UE handover information is provided to the non-anchor node. The UE handover information includes first radio handover information relating to handover of the connection from the first mobile radio communication system to the second mobile radio communication system and second handover information relating to handover from the second mobile radio communications system to the first mobile radio communications system. The non-anchor node forwards to a node in the target network the UE handover information having the protocol format recognized by that node.

Abstract: A system and method for achieving interoperability between telecommunication servers such as Mobile Switching Centers (MSCs) in a mobile communication network by automatically distributing capability and configuration information between the MSCs. Whenever one of the MSCs is started-up, or undergoes any other procedure that changes the configuration or capabilities of the MSC, the start-up MSC automatically sends its capability and configuration information to its neighboring MSC's. The neighboring MSCs store the information and return their own information to the start-up MSC for storage. Thereafter, whenever a service is initiated, the MSCs send to each other, only service-related information that the stored capability and configuration information indicates is supported.
