Problems solved by technology

[0011] However, the standard organization did not further clarify the deployment method of IWF, which means that the deployment method of IWF is determined by the operator itself, and it does not specify the routing mechanism of the message.

Abstract

The invention discloses a method for realizing user routing. The method is used for a mobile communication system comprising a mobility management entity MME, visited network subscription user positioning function SLF-A, visited network intercommunication function IWF-B, home network subscriber positioning function SLF-B, and a home network user server HSS / HLR. When the MME or IWF detects that interaction with the HSS / HLR of a given user is required to be performed, the network address information of next hop can be obtained through the way that number analysis is performed to the identification information of the user in the local area or the way that the subscription user positioning function SLF is inquired, and a request message is sent to the network address information, the network address information can be visited network intercommunication function IWF address information, home network intercommunication function IWF address information or home network user server address information, and is finally routed to the HSS / HLR.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method for realizing user routing in the architecture evolution of the mobile communication system. Background technique [0002] With the continuous emergence of new technologies, 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) needs to consider the continuous evolution and enhancement from the radio interface to the core network in the evolution of the system architecture in the future mobile communication field, so that in the next ten years Maintain 3GPP's technological first-mover advantage in the field of mobile communications within the year, and provide satisfactory support for the growing demands of operators and users. The evolution project (System Architecture Evolution, SAE, System Architecture Evolution) of the all-IP-oriented packet domain core network, now renamed EPS (Evolved Packet System, Evolved Packet System), was launched unde...
