Problems solved by technology

However, in the actual Diameter node network, the Diameter client and server are often not connected through a direct connection, and some intermediate agents will be passed in the middle (the connection between the Diameter client and the server through an intermediate agent becomes a non-direct connection) , if all rely on static configuration domain routing, it will increase the corresponding static maintenance workload

Embodiment 1

[0052] Figure 6 It is a structural block diagram of the Diameter system according to embodiment 1, such as Figure 6 As shown, the system based on this embodiment includes:

[0053] The Diameter client is used to send Diameter messages to the Diameter server, and perform authentication, authorization, and accounting operations with the Diameter server.

[0054] Diameter agent (also known as Diameter relay agent), including relay, proxy agent, redirection agent, translation agent, etc. As an intermediate node in the Diameter system, it forwards the message or forwards it after processing, and assists in completing the AAA operation between the client and the server.

[0055] The Diameter server is used to transmit Diameter messages with the Diameter client, perform authentication, authorization, and accounting operations, and return the processing results to the client.

[0056] The following will take the above three Diameter node networking as an example to illustrate the...

Embodiment 2

[0111] Figure 7 According to the schematic structural diagram of the billing system in Embodiment 2, the system includes: Diameter Client 70, Diameter Relay 71, Diameter Server 72, and Diameter Server 73, wherein,

[0112] The Diameter Client 70 is configured to send an AAA (Authentication, Authorization, Accounting) request message to Diameter Server 72 or Diameter Server 73 through the Diameter protocol or receive a Diameter AAA (Authentication, Authorization, Accounting) response returned by Diameter Server 72 or Diameter Server 73 information;

[0113] Here, the Diameter Client 70 may be a SCSCF or a Gateway GPRS Support Node (GGSN) or the like.

[0114] The Diameter Relay 71 acts as a Diameter relay node to forward the request message sent by the Diameter Client 70 , and the request message sent by the Diameter Client 70 can be sent to the Diameter Server 72 or to the Diameter Server 73 through the Diameter Relay 71 .

[0115] The Diameter Server 72 and Diam...

Abstract

The invention discloses a route discovery method and diameter nodes in a non-direct connecting diameter system. The method comprises the following steps: adjacent Diameter nodes in the non-direct connecting Diameter system exchange respective route table summary information; each Diameter node which receives the route table summary information updates the respective route table according to the received route table summary information; and dynamic route discovery is carried out according to the updated route table. The route discovery method of the invention avoids the manual configuration of a domain route, reduces the workload, and improves the operating efficiency of a system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a route discovery method and a Diameter node in a non-directly connected Diameter (Diameter) system. Background technique [0002] Since the birth of network communication technology, Authentication, Authorization and Accounting (AAA for short) has become an indispensable operation basis for operators. With the evolution of the third-generation mobile communication system to an all-IP-based network architecture, the Diameter protocol gradually replaces the Radius protocol as a new generation of AAA technology, and because the Diameter protocol has strong scalability and security However, international standard organizations such as the International Telecommunication Union (ITU), the 3rd Generation Partnership Project (3GPP) and the 3rd Generation Partnership Project 2 (3GPP2) have officially The Diameter protocol is used as the next generation network (Next Generation Network,...
