Abstract

The invention discloses a method and interworking function device for converting routing parameters. The method comprises the steps: when a first request message sent by a Diameter node is received, extracting a Diameter node host name contained in the first request message; using a global title related to the Diameter node host name in a dynamic mapping table as a global title of the Diameter node; judging whether the first request message contains a host name of a MAP node used as a called party or not; if the host name of the MAP node is contained, converting the host name of the MAP node into the global title of the MAP node according to a preset rule, and using the global title as a called user address; if the host name of the MAP node is not contained, using the global title corresponding to an IMSI in user identification as the called user address; sending a second request message to the MAP node, wherein the second request message comprises the global title and the called user address of the Diameter node. Routing parameter conversion is performed between a Diameter protocol and a MAP protocol through the IWF, and interconnection and interworking of different protocols between LTE and a 2G/3G network are ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for converting routing parameters and an interworking function device. Background technique [0002] In LTE (Long Term Evolution, long-term evolution) and 2G / 3G roaming technology, 3GPP (3rd Generation Partnership Project, third generation partnership project) stipulates that Diameter protocol and MAP ( Mobile Application Part, the conversion of the mobile application part). The Diameter protocol and the MAP protocol adopt different routing mechanisms. The Diameter protocol uses the domain name (realm) and the host name (host name) for routing, while the MAP protocol mainly uses the Global Title (Global Title, referred to as: GT) for routing in the mobile network. At present, 3GPP has not standardized the IWF conversion method for the above-mentioned routing data of the two protocols, and there are still problems in the research and development of the actual IWF equipment and ...
