Method for addressing interworking gateways

Abstract

The invention provides a method for addressing interworking gateways. The method comprises the following steps that: when a network element node initiates user registration to an HSS through a home network intercommunication gateway H-IWF of a user, the network element node or a visit network intercommunication gateway V-IWF of the user between the network element node and the H-IWF sends a registration request message carrying node identification and equipment number of the network element node to the HSS through the H-IWF; the HSS records the association relation between the received node identification and the equipment number; when the HSS needs to send a request message to the network element node through the H-IWF, the HSS acquires the equipment number according to the node identification and sends the request message carrying the equipment number to the H-IWF; and the H-IWF uses the equipment number to perform routing addressing on the network element node and forwards the request message sent by the HSS to the network element node.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to an addressing method of an intercommunication gateway. Background technique [0002] With the continuous emergence of new technologies, 3GPP (3rd Generation Partnership Project) needs to consider the continuous evolution and enhancement from the wireless interface to the core network in the future evolution of the system architecture in the field of mobile communications. During the year, we will maintain our first-mover advantage in the field of mobile communications and provide satisfactory support to the growing needs of operators and users. The evolution project (System Architecture Evolution, SAE) of the packet domain core network for all IP (Internet Protocol, Internet Protocol), now renamed EPS (Evolved Packet System), was launched under this background. The goal of SAE is to "make a portable 3GPP system framework with high data rate, low latency, data packetization, and su...

Problems solved by technology

[0012] (1) In the roaming scenario, the IWF deployed in the user's home network cannot effectively route the request message for the HSS or HLR connected to it; and if the request message sent by the HSS or HLR needs to be deployed in the visited The IWF of the network is sent to the NE node, and the IWF of the visited network does not save the binding relationship (or association relationship) between the device number of the NE node and the node ID, and the IWF of the visited network cannot correctly perform routing search. site

[0013] (2) For an application scenario with two IWFs, when one of the IWFs is responsible for allocating device numbers, the binding relationship information between the device number and the corresponding node ID cannot be sent to the other IWF
