Problems solved by technology

However, the current Diameter protocol does not support the transmission of multicast-related information, so peers using Diameter as the interface protocol cannot exchange multicast information to know the relevant status of the network, thus affecting the operation process related to multicast control , which limits the development of multicast services and cannot effectively utilize network resources

Embodiment 1

[0057] In this embodiment, the method and system for transmitting multicast information are introduced in detail.

[0058] Figure 5 It is a specific flow chart of the method for transmitting multicast information in Embodiment 1 of the present invention. Such as Figure 5 As shown, the method includes:

[0059] Step 501, set multicast information attribute-value pairs in the Diameter protocol.

[0060] The multicast information attribute-value pairs set in the Diameter protocol in this embodiment include: multicast address attribute-value pairs, multicast source address attribute-value pairs, multicast source address number attribute-value pairs, multicast indication information type attribute-value pairs and One or any combination of attribute-value pairs of multicast description information.

[0061] The specific content and format of the above-mentioned various types of multicast information attribute-value pairs are introduced in detail below.

Embodiment 2

[0126] This embodiment introduces a detailed implementation manner of a method and system for a device supporting the Diameter protocol to authorize a multicast service.

[0127] Figure 7 It is an abstract network policy control model, and this embodiment implements multicast service authorization in this model. Such as Figure 7 As shown, the model includes Application Function (AF), Policy Decision Point (PDP), Policy Enforcement Point (PEP) and User Equipment (UE). Wherein, the interface between the application function (AF) and the policy decision point (PDP), and the interface between the policy decision point and the policy enforcement point (PEP) can adopt the Diameter protocol. Referring to the Diameter protocol, the PDP here acts as a Diameter server to handle multicast service requests in a certain network domain, and the AF and PEP act as Diameter clients to initiate multicast service requests to the PDP. The system composed of PDP, PEP and AF is Figure 4 A sp...

Abstract

The embodiment of the invention discloses a method for transmitting multicast messages. The method comprises the following steps that: in a Diameter protocol, multicast message attribute value pairs are set; a Diameter server or a Diameter client end determines a multicast message attribute value pair corresponding to a session according to the requirement of the session, and a multicast message of the session is transmitted through a Diameter message carried with an appointed multicast message attribute value pair. The method can realize the transmission of the multicast message between entities which support the Diameter protocol. The embodiment of the invention also discloses a method for authorizing multicast services, and the method can realize the authorization of multicast services between peer ends supporting the Diameter protocol based on the set multicast message attribute value pair. The embodiment of the invention also discloses a system for transmitting multicast messages and a system for authorizing multicast services.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for transmitting multicast information and authorizing multicast services. Background technique [0002] Authentication, Authorization, and Accounting (AAA) has been the basis of network operations since the birth of the network. The use of various resources in the network needs to be managed by authentication, authorization, and accounting. In order to run the AAA function on the Internet, IETF defined the remote dial-in user authentication service protocol (RADIUS, RFC 2058) in 1997, and then proposed an updated version of RADIUS, named Diameter (IETF defined it in RFC 3588 at the end of 2003) Diameter's basic protocol), used to provide authentication, authorization and accounting (AAA) services for many access technologies. [0003] The Diameter protocol is actually divided into two parts: the basic Diameter protocol and a series of applications that complete t...
