Problems solved by technology

[0021] use figure 1 The described method realizes different CGs to manage users in different numbers. The disadvantage is that the corresponding relationship between the user number and the CG domain name needs to be set on the IMS network element. At the same time, the CG domain name needs to be obtained according to the user number during the call process and sent to the MGCF network element. This also increases the message flow between IMS and MGCF network elements

Embodiment Construction

[0052] The present invention provides a Diameter routing method, comprising: after a C network user establishes a call with an IP Multimedia Subsystem (IMS) user, in the process of sending charging information to the IMS network, using the user number of the IMS user as a Diameter message The primary key of a route to look up a route.

[0053] Wherein, when the C network user calls the IMS user, the called number is used as the primary key of the Diameter message routing; when the IMS user calls the C network user, the calling number is used as the primary key of the Diameter message routing.

[0054] Wherein, the media gateway control function (MGCF) configures and saves the mapping relationship between the user number of the IMS user and the charging gateway;

[0055] When a C network user calls an IMS user, it includes:

[0056] The MGCF extracts the called number, searches the routing table using the called number as the primary key, obtains the corresponding charging gat...

Abstract

The invention provides a Diameter routing method which comprises the following step: after setting up a call between a C network user and an IP multimedia subsystem (IMS) user, using the user number of the IMS user as a prime key word for Diameter message routing to look for routes in the process of transmitting charging information to the IMS network. The invention also provides a Diameter routing system. The method uses the calling number or the called number in the call as the prime key word for Diameter message routing, thereby reducing the message flow.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a Diameter routing method and system. Background technique [0002] Today, the communication network system is widely used, in order to ensure the security and commercial use of the communication network, the use of various resources in the communication network needs to support authentication, authorization and billing functions through the communication network system. At present, two mainstream AAA (Authentication, Authorization, Accounting, authentication, authorization, accounting) application protocols used in communication network systems are Radius and Diameter protocols. The Diameter protocol is a new generation of AAA technology, which overcomes many disadvantages of the Radius protocol, and is attracting more and more attention because of its strong scalability and security guarantee. In international standard organizations such as ITU (International Telecommunicat...
