Embodiment Construction

[0023] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0024] A distributed EPC core network of the present invention, in the original mobile management entity (Mobile ManagementEntity, MME), server gateway (Serving Gateway, SGW), PDN gateway PGW (Packet Data NetworkGateway) and home subscriber server (Home Subscriber Server, On the basis of network element modules such as HSS), a community subscriber server (Community Subscriber Server, CSS) is added, and the mobile management entity MME is connected to the home subscriber server HSS, the community subscriber server CSS, the server gateway SGW and the PDN gateway PGW, and the server gateway and PDN gateway connection, the community user server is used to connect with community user servers of other distributed EPC core networks; it is used to solve the problem of user roaming between multiple distributed EPC core networks. The user data of the CSS mo...

Abstract

The invention provides a distributed EPC core network user roaming control method and an EPC core network. By adding a community user server CSS and a home query mechanism to the traditional EPC network architecture, the roaming user attribution problem is queries, when a user in a distributed EPC core network in an existing impendent network mechanism of distributed EPC core networks to other distributed EPC core networks, the user can perform related services in the other distributed EPC core networks, thereby providing a more convenient and flexible LTE network and forming the LTE network with multiple point-like coverage interconnections, simplifying the complicated interconnection and interworking network architecture, and facilitating maintenance and management. Compared with the traditional network architecture, the investment cost of the network construction is greatly reduced, the investment cost of the network construction is greatly reduced, and the query mechanism is very simple and fast.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to user roaming control methods of each distributed EPC core network and the EPC core network. Background technique [0002] The fourth-generation wireless data network LTE (Long Term Evolution, Long Term Evolution) is a new generation of international mainstream broadband wireless mobile communication technology. It is oriented to packet domain services and cannot provide circuit domain services like traditional 2G / 3G networks. Traditional The LTE system adopts a tree-like network architecture and adopts Evolved Packet Core (EPC) centralized deployment, which is more suitable for large-scale network operations of operators. However, with the surge of wireless data traffic and the application of LTE-based wireless private networks, A miniaturized EPC core network based on a distributed architecture is in use. Each EPC core network includes a home user server...
