Abstract
The present invention discloses a method for realizing the user multicast jurisdiction control, which comprises the following procedures: (1) a DSLAM equipment obtains the user multicast jurisdiction control list, and maintains the user multicast jurisdiction control list; (2) the user requests the multicast channel, the set-top box of the user generates a protocol packet, and transmits the protocol packet to the DSLAM equipment; (3) the DSLAM equipment judges the authority of the user according to the user multicast jurisdiction control list after receiving the message of an IGMP entering request; (4) if the user has an authority, the multicast data stream is duplicated and is given to a user. When the IPTV service is developed, the management to the user multicast jurisdiction control function is realized.
Description
Technical field
The present invention relates to the IPTV business, specifically, relate to a kind of method that realizes user multicast power control.
Background technology
Country is formulating the relevant criterion of IPTV at present, in 6 standards having formulated, " IPTV is to the specification requirement of DSLAM equipment " standard and DSLAM (Digital Subsriber LineAccess Multiplexer, digital subscriber line access multiplex) equipment is closely related, and as long as the current DSLAM equipment of supporting the IPTV business to carry out need be supported the control of the user multicast power stipulated in this standard certainly.The related request of stipulating in our the DSLAM equipment realization standard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that realizes user multicast power control, solved and carried out the IPTV business, adopt multicasting technology operation live telecast video traffic, carry out the control of multicast and when duplicating with DSLAM equipment, because existing multicast protocol lacks the management to the multicast user, can't carry out the problem of effective multicast authority control to the user.
In order to address the above problem, the invention provides a kind of method that realizes user multicast power control, be applied in the DSLAM equipment under the IPTV business, it comprises the steps:
(1) DSLAM equipment obtains the user multicast power control table, and the control table of maintenance customer's multicast authority;
(2) user asks multicast channel, and user's STB (set-top box) set-top box produces protocol massages, sends to DSLAM equipment;
(3) after DSLAM equipment received IGMP (Internet Group Message Protocol, the Internet group message protocol) Join (joining request) message, this user's authority was judged in control table according to user multicast power;
(4) user then duplicates multicast traffic stream to the user if authority is arranged.
Method of the present invention, wherein, described step further comprises in (4): the user continues the user and asks other multicast channels if lack of competence is then refused multicast traffic stream and duplicated to the user.
Further, method of the present invention, wherein, described user multicast power control table communicates acquisition by DSLAM equipment and business management system.
Further, method of the present invention, wherein, described user multicast power control table comprises: multicast channel access control right table and channel program summary table.
Method of the present invention, wherein, described step further comprises in (3): according to the multicast ip address that message carries, judge this user's authority in the user multicast power control table.
The technical solution of the present invention, after implementing, when the television video business of IPTV realized by multicasting technology, DSLAM equipment was effectively supported the multicast authority controlled function based on user port, specific implementation comprise:
(1) support only to allow the user to add the multicast group of mandate or the multicast group of permission preview;
(2) be supported on the user port its authority of watching of control to each multicast group business: as forbid, preview, permission;
(3) support based on each user the multicast access rights to be set, each user has independent authority configuration, and each user comprises whether allowing to visit certain multicast group, whether allow certain multicast group of preview to the optional independent setting of the authority of each program;
(4) support the number of the multicast group that can add to limit to user port;
(5) support the user is added the control of multicast group, the support of DSLAM equipment realizes the multicast control mib storehouse of user port by SNMP (SimpleNetwork Management Protocol) network management protocol.DSLAM equipment is supported the static configuration mode, and optional support is based on the dynamic control of webmaster or other agreements;
(6) support multicast authority business packet (Package), each business packet (Package) can comprise any a plurality of channel (multicast group).
Description of drawings
Fig. 1 is the basic flow sheet of method described in the embodiment of the invention.
Embodiment
As shown in Figure 1, the implementation step that the method described in the embodiment of the invention is concrete is as follows:
Step 101:DSLAM equipment is by communicating by letter with business management system SMS (Service ManagementSystem), user's multicast authority control table on the acquisition equipment generally comprises information such as multicast channel access control right table CAC (Channel Access Control), channel program summary table;
Step 102: when validated user was watched a multicast channel in request, user's STB set-top box then can produce an IGMP join (joining request) message, sends to DSLAM equipment;
After step 103:DSLAM equipment received user multicast request IGMP Join (joining request) message, according to the multicast ip address that message carries, whether this user of inquiry had the authority of this channel in the user multicast power control table;
Step 104: but the user then accepts user's request if perhaps authority of preview is arranged, and multicast traffic stream is duplicated to the user, changes step 106; Otherwise the refusal multicast traffic stream duplicates to the user, changes step 105; Step 105: the user is rejected, and watches the group broadcasting program less than request, continues other multicast channels of request, changes step 102;
Step 106: the user watches the multicast channel program of request.
In the described method of the embodiment of the invention, the multicast control authority table information that DSLAM equipment obtains this equipment user is to communicate acquisition by DSLAM equipment and business management system SMS, communicates acquisition and the user multicast power control information among the SMS is the OSS system of SMS system and IPTV.
In the described method of the embodiment of the invention, the control of user's multicast authority only allows the user to add the multicast group of mandate or the multicast group of permission preview in the DSLAM equipment, its authority of watching of control on user port, authority to each multicast group have forbid, preview, permission.
In the described method of the embodiment of the invention, user's multicast authority control in the DSLAM equipment, be based on each user the multicast access rights are set, each user has independent authority configuration, each user is to the optional independent setting of the authority of each program, comprise and whether allow to visit certain multicast group, whether allow certain multicast group of preview; Also support user right configuration in addition based on multicast authority business packet (Package), each business packet (Package) can comprise any a plurality of multicast channel, after user's configuration belonged to certain concrete multicast authority business packet, then this user just had the corresponding authority of all multicast channels in this multicast authority business packet.
Above-mentioned embodiment describes the present invention with preferred embodiment, should not be regarded as limitation of the scope of the invention.Equally, according to the description of technical scheme of the present invention and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection range of claim of the present invention.
