Abstract

The present invention provides a method and a device for transmitting a multicast preview service, wherein the method includes the following steps: looking up, in a management object and / or attributes of the management object, an attribute carried in a multicast joining request message according to a predetermined sequence, wherein the management object and / or the attributes of the management object includes at least one of the following: Multicast Operations Profile (MOP), an authorization group of Extension Multicast Operations Profile (EMOP), an Allowed preview groups table of Multicast Subscriber Control (MSC), and a preview group of EMOP (S102); forwarding or stopping forwarding to a user a service requested by the multicast joining request message according to a lookup result (S104). The present invention solves the problem in conventional art that multicast services of multiple Service Providers (SPs) cannot be managed, and improves the multicast control method.

Description

technical field

[0001] The present invention relates to the field of GPON (Gigabit Passive Optical Network, Ethernet Passive Optical Network) communication, in particular, to a transmission method of multicast preview service. Background technique

[0002] GPON is a broadband access technology that adopts point-to-multipoint network structure, passive optical fiber transmission mode, frame encapsulation based on GEM (GPON Encapsulation Method), and provides multiple comprehensive services. GPON consists of three parts: central office equipment OLT (Optical LineTerminal Optical Line Terminal), user end equipment ONU (Optical Network Unit Optical Network Unit) and optical distribution network ODN (Optical Distribute Network Optical Distribution Network). With the large-scale application of GPON technology in recent years, how to develop controllable multicast services on GPON has become a subject worth studying.

[0003] Gem port (GEM encapsulation port) is a logical channel ...

Examples

Embodiment 1

[0034] figure 1 It is a preferred flowchart of a method for controlling a multicast service according to an embodiment of the present invention, which includes:

[0035] S102. Search the management object and / or the attributes of the management object for the attributes carried in the multicast join request message in a predetermined order, wherein the above-mentioned management object and / or the attributes of the management object include at least one of the following: multicast operation Template (MOP), authorization group of extended multicast operation template (EMOP), multicast preview permission table of multicast user control (MSC), preview group of EMOP;

[0036] S104. Forward or stop forwarding the service requested by the multicast join request message to the user according to the search result.

[0037] In this preferred embodiment, by searching the management object and / or the attributes of the management object in a predetermined order for the attributes carried ...

Embodiment 2

[0052] figure 2 It is a preferred structural diagram of a multicast service control system according to an embodiment of the present invention, which includes: a search unit 202, configured to search for a multicast join request message in a management object and / or attributes of a management object in a predetermined order The attributes carried in the text, wherein the above-mentioned management object and / or the attributes of the management object include at least one of the following: multicast operation template (MOP), authorization group of extended multicast operation template (EMOP), multicast user control ( The multicast preview permission list of the MSC, the preview group of the EMOP; the transmission unit 204 is used to forward or stop forwarding the service requested by the above-mentioned multicast join request message to the user according to the search result.

[0053] In this preferred embodiment, by searching the management object and / or the attributes of th...

Embodiment 3

[0068] This embodiment follows the existing G.988OMCI standard management interface definition, the OLT sends multicast service-related management information and user UNI side multicast service access selection control information to the ONU side, and the ONU performs user multicast according to the configured related information Protocol access management control.

[0069] 1. In order to support the management and control of multi-SP multicast services, the OLT needs to configure parameters such as the multicast channel authority control table of the multicast service channel into the EMOP (extended multicast operation template) management object of the ONU:

[0070] 1) In the multicast channel permission control table, the access permission (watch or preview) can be specified for each multicast channel, and the preview parameters related to the preview permission can be configured, including the number of previews, the maximum duration of preview, and the minimum interval of...
