Problems solved by technology

Therefore, the mobile management entity will not provide the ISDN number to the IWF (Inter Working Function, conversion function entity) network element, and the IWF will not be able to provide the corresponding ISDN number to the home location register, causing the home location register in the original GPRS network to fail. The IWF addresses the mobility management entity; similarly, the mobility management entity cannot address the home location register through the IWF

Embodiment 12

[0112] Embodiments 12 to 14 are applicable to a situation where a user only uses one Diameter node at the same time, but in a mobile network, sometimes a user may access two Diameter nodes at the same time, for example, during handover. Therefore, Embodiment 15 of the present invention provides a solution in this case, which can be regarded as an extended application of Embodiment 12.

[0113] In Embodiment 15 of the present invention, one IWF network element can serve one or more Diameter nodes and MAP nodes, such as Figure 17 shown. Among them, the Diameter node is the client end, and the MAP node is the Server end. Because a user may use two Diameter clients at the same time during certain periods of time, IWF provides two shared ISDN numbers. When a user uses the first Diameter client to access the MAP server, the IWF assigns an ISDN number for this user, and when the user uses the second Diameter client served by the IWF to access the same MAP server, the IWF assigns t...

Abstract

The invention provides a heterogeneous addressing conversion method comprising following steps: The conversion function entity IWF converts the Diameter protocol/MAP protocol message transmitted by Diameter protocol/ MAP protocol node to MAP protocol/Diameter protocol message, uses a first address/ a second address as source address, or a first identifier/ a second identifier as source identifier, sends the converted MAP protocol/Diameter protocol information to MAP protocol/Diameter protocol node. The invention also provides a heterogeneous addressing conversion system and equipment. In the embodiment of the invention provides mutual node identifier conversion method and corresponding addressing relation of every identifier, solves problem of incapable of communicating because of different identifier addressing mode when Diameter node and MAP node communicates by converting function.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a heterogeneous addressing conversion method, system and equipment. Background technique [0002] In the GPRS (General Packet Radio Service, general packet radio service) network, the service node accesses the home location register through the Gr interface, such as figure 1 As shown, the Gr interface is based on the MAP (Mobile Application Part, mobile application part) protocol, and the home location register is used to perform network access authentication and location management on the mobile terminal. In the evolved GPRS network, the mobility management entity is the evolution entity of the control function of the original service node, and the home subscriber server is the evolution entity of the original home location register, and the mobility management entity accesses the home subscriber server through the S6 interface, such as figure 2 As shown, the S6 interfa...
