Title:
METHOD FOR SENDING ROAMING SIGNALING MESSAGE, RELATED DEVICE AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/063057
Kind Code:
A1
Abstract:
Provided in the present application is a method for sending a roaming signaling message so as to solve the problem in the art that the efficiency in sending a roaming signaling message is low due to multiple signaling interactions being required between a visited core network device and a visited SEPP device to obtain the identifier of the virtual visited SEPP device. In the present application, after receiving a roaming signaling message, the visited core network device adds the identifier of a home core network device and the identifier of the visited SEPP to the roaming signaling message, and then sends a roaming signaling message including the identifier of the home core network device and the identifier of the visited SEPP to the visited SEPP, so that the visited SEPP can forward the above-mentioned roaming signaling message to the home network according to the identifier of the home core network device, thereby reducing the signaling interaction between the visited SEPP and the visited core network device, and improving the efficiency of message forwarding.
