METHOD AND NETWORK ENTITY FOR REGISTERING A USER ENTITY WITH A COMMUNICATION NETWORK VIA ANOTHER COMMUNICATION NETWORK

摘要

The present invention relates to a network entity (101) for registering a user entity (103) with a first communication network (105), wherein the user entity (103) and the network entity (101) providing access to the first communication network (105) are registered with a second communication network (107). The network entity (101) has a transceiver (109) for transferring at least one registration message for registering said user entity (103) with the first communication network (105) between the user entity (103) and the network entity (101) over the second communication network (107).
