摘要

The disclosure relates to a method for initiating a roaming communication link with a user equipment (UE) (202) in a visited communication network (240), in particular in a network slice of the visited communication network (240), the method comprising: transmitting a registration request (203) by the UE (202) to a network entity (252, 251) of the visited communication network (240), wherein the registration request comprises an identity (UE ID) of the user equipment (UE ID); detecting by the network entity (252, 251) of the visited communication network (240), based on the UE ID, that the registration request (203) is related to a roaming communication with the UE; determining by the network entity (252, 251) of the visited communication network (240) a home communication network (210) of the UE (202); establishing by the network entity (252, 251) of the visited communication network (240) a communication link (206, 207) to a network entity (221, 222) of the home communication network (210); and initiating the roaming communication link with the UE (202) via the network entity (221, 222) of the home communication network (210).
