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: DiameterClient70, DiameterRelay71, DiameterServer72 and DiameterServer73, wherein,

[0112] The DiameterClient70 is configured to send an AAA (authentication, authorization, accounting) request message to DiameterServer72 or DiameterServer73 through the Diameter protocol or receive a Diameter AAA (authentication, authorization, accounting) response message returned by DiameterServer72 or DiameterServer73;

[0113] Here, the DiameterClient70 may be a SCSCF or a Gateway GPRS Support Node (GGSN) or the like.

[0114] The DiameterRelay71 acts as a Diameter relay node to forward the request message sent by the DiameterClient70, and the request message sent by the DiameterClient70 can be sent to the DiameterServer72 or to the DiameterServer73 through the DiameterRelay71.

[0115] The DiameterServer72 and DiameterServer73 are used to process the reque...

Abstract

The invention discloses a route discovery method and a diameter node in a non-directly connected Diameter system. The method includes: adjacent Diameter nodes in a non-directly connected Diameter system exchange their respective routing table summary information; receiving the routing table summary information The information Diameter node updates its own routing table according to the received routing table summary information; performs dynamic route discovery according to the updated routing table. The invention avoids manual configuration of domain routing, reduces workload and improves system operating efficiency.

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 (International Telecommunication Union, referred to as ITU), the 3rd Generation Partnership Project (3GPP for short), and the 3rd Generation Partnership Project 2 (3GPP2) have officially adopted the Diameter p...
