Abstract
A group broadcasting method with the service node to be controlled is to set a service control platform in the system which uses multicast server to carry out the multicast to the client via service node. It can identify the client, control the broadcasting content of the service node and carry out the expansion for adapting identification and paymen accounting requirement of remote identification dialing of client service agreement between the service control platform and service node. When the client applies for jointing the multicast to the service node, the service node will go to the service control platform for identifying. If the identification is successful the broadcast content will be duplicated to the client, other wise not.
Description
Technical field
The present invention relates to the IP field, the especially a kind of method of multicasting that can control the broadcast of multicast content.
Background technology
Let us elder generation is talked from the mode of the broadcast program of IP network.On the IP network, program can be propagated with clean culture, multicast and three kinds of forms of broadcasting.The i.e. man-to-man propagation from the program source to user of clean culture, broadcasting is the propagation of a program source to huge numbers of families, as the broadcasting station, and multicast circle is between the two, it is the propagation from the program source to the internal user a cohort inside, and this mode still can often run in practice.The solution of multicast has two kinds at present: a kind of is the scheme that does not authenticate control fully; A kind of is to arrive first the assigned address authentication by proprietary terminal to initiate the scheme that application adds multicast again.
One, there is not the authentication controlling schemes
This scheme as shown in Figure 1.Our roughly composition of multi-cast system as can be seen in Fig. 1, the user inserts unified service node by local area network (LAN) Layer 2 switch LAN SW, asymmetric digital subscriber line ADSL, Very-high-speed Digital Subscriber Line VDSL, Hybrid Fiber Coax HFC access device etc., service node receives the multicast of the content of multicast server Multicast Server, duplicate play content to the user then, detailed process is such:
1, multicast server Multicast Server multicasts to service node ISN to programme and content.
2, the user opens a terminal, and service node ISN delivers to terminal to programme by multicast.
3, the user clicks certain channel in terminal, and user side adds this channel multicast group by internet multicast IGMP agreement to service node ISN request.
4, service node ISN duplicates play content to the user.
5, the user finishes this and watches, and user side software sends to service node ISN and leaves multicast group message.
6, service node ISN stops to this user multicast content.
The shortcoming of this method is, the process that in method, does not at all have inspection user identity and inspection user whether to have the right to watch some program, the process that promptly lacks authentication, so just be unfavorable for the network equipment is carried out control and management to the user multicast program, can not solve the charging problem of multicast well.
Two, arrive first the assigned address authentication by proprietary terminal and initiate the scheme that application adds multicast again
This method is that Infovalue company adopts, as shown in Figure 2.Can see that in the drawings in this multicast mode, internet content supplier ICP side has three entities: multicast server Multicast Server, multicast management device Multicast Manager, User Manager UserManager.Multicast server Multicast Server finishes the broadcast of multicast content, multicast management device Multicast Manager finishes the management of multicast server Multicast Server, comprise the issue of the determining of channel content, channel, User Manager User Manager finishes content authentication.User side adopts special-purpose user side program.
The detailed process of this method is such:
1, the user is by the multicast server MulticastServer of clean culture access the Internet content supplier ICP, and mutual with it, and multicast server Multicast Server finishes the setting of user side.The mode of clean culture was carried in front, here the user carries out man-to-man the contact by the mode and the multicast server Multicast Server of clean culture earlier, in this step, multicast server MulticastServer can finish the basic setup of user side by the process in this step.
2, multicast server Multicast Server multicasts to service node ISN to programme and content.
3, user side software restarts, multicast server Multicast Server is pushed to user side to programme by multicast automatically, multicast management device Multicast Manager is pushed to user side to the authentication positional information simultaneously, thereby the user knows to where going to authenticate.
4, the user clicks certain channel, and user side software arrives the authentication of assigned address User Manager UserManager place automatically, and authentication adds this channel multicast group by internet multicast IGMP agreement to service node ISN request by the back user side.
5, service node ISN duplicates play content to the user.
6, the user finishes this and watches, and user side software sends to service node ISN and leaves multicast group message.
7, service node ISN stops to this user multicast content.
What shortcoming does this method have? this method is utilized special-purpose terminal to authenticate and then is applied for adding.It is the user side software by a terminal, multicast server MulticastServer is pushed to user side to programme automatically, multicast management device Multicast Manager is pushed to user side to the authentication positional information simultaneously, user side software arrives the authentication of assigned address User Manager User Manager place automatically then, that is to say, this method is that the program that depends on the user side software set is carried out, in case user side software is changed or is cancelled, the user just can not authenticate direct adding multicast, pretends to be the possibility that adds multicast very big.
Summary of the invention
The purpose of this invention is to provide a kind of business node-controlling multicasting method, it can either combine the multicast and the authentication of the network equipment, realization is carried out control and management to the network equipment to the user multicast program, simultaneously do not rely on special-purpose terminal again and carries out, thereby preventing that user side software from being changed or being cancelled pretends to be the possibility that adds multicast.
For achieving the above object, solution of the present invention is: a kind of business node-controlling multicasting method, carry out in the system of multicast to the user through service node by multicast server at one,
A, a professional controlling platform is set, it can authenticate the user, content play to service node is controlled, and the remote authentication dial-in user service agreement that comprises Access_Request message, Access_Response message, Accounting_Request message and Accounting_Response message between professional controlling platform and the service node is carried out adaptive authentication and the expansion of the requirement of chargeing;
B, when the user after the service node request adds multicast, service node is to professional controlling platform authentication, authentication success duplicates broadcast contents to the user, authentification failure does not then duplicate broadcast contents;
C, service node charges to professional controlling platform request after the user duplicates broadcast contents;
D, user finish to watch, and are stopped to charge to professional controlling platform request by service node, and stop to user multicast.
Specifically, in step a, the remote authentication dial-in user service agreement between professional controlling platform and the service node is carried out following expansion:
I, newly open up a multicast group parameter, show the user will watch the program of which group for Access_Request message and Access_Response message in the remote authentication dial-in user service agreement;
Ii, newly open up a multicast group parameter and begin billing parameter, stop billing parameter, show that respectively the program to which group charges, begins and stops to charge for the Accounting_Request message in the remote authentication dial-in user service agreement and Accounting_Response message.
Step b specifically comprises such process:
B1, user side software startup, multicast server multicasts to the user side interface to programme;
B2, user add certain channel by clicking to the service node request;
B3, service node send the Access_Request message that has user name, user cipher, multicast group parameter to professional controlling platform, and professional controlling platform authenticates parameter;
B4, professional controlling platform have the Access_Response message of user name, user cipher, multicast group parameter to the service node loopback, and authentication success duplicates broadcast contents to the user.
In addition, in the step b2 of step b, the user adds certain channel to the Layer 2 Multicast device request earlier, then should request to the service node transparent transmission by Layer 2 Multicast equipment.In the step b4 of step b, professional controlling platform is behind service node loopback Access_Response message, and service node is transmitted to Layer 2 Multicast equipment to this message, duplicates broadcast contents by Layer 2 Multicast equipment to the user.
Step c specifically comprises such process:
C1, send the Accounting_Request message that has user name, user cipher, multicast group, beginning billing parameter by service node to professional controlling platform, professional controlling platform begins to charge;
C2, have the Accounting_Response message of user name, user cipher, multicast group, beginning billing parameter to the service node loopback by professional controlling platform.
Steps d specifically comprises such process:
D1, user finish to watch, and user side software sends the message of leaving the multicast group to service node;
D2, send the Accounting_Request message that has user name, user cipher, multicast group, stops billing parameter to professional controlling platform by service node, professional controlling platform stops to charge;
D3, have user name, user cipher, multicast group, stop the Accounting_Response message of billing parameter to the service node loopback, stop to user multicast by professional controlling platform.
In addition, in the steps d 1 of steps d, user side software can send to Layer 2 Multicast equipment earlier and leave multicast group message, and Layer 2 Multicast equipment is to this message of service node transparent transmission then.In the steps d 3 of steps d, stop to user multicast by Layer 2 Multicast equipment.
Because the present invention is provided with a professional controlling platform that the user is authenticated, when the user after the service node request adds multicast, service node is to professional controlling platform authentication, authentication success duplicates broadcast contents to the user, this authentication is not carried out in dedicated user terminal, carry out but force at service node, so he its problem of both having solved authentication and having chargeed, do not rely on special-purpose terminal again and carry out, thereby having prevented that user side software from being changed or being cancelled pretends to be the possibility that adds multicast.

Specific implementation
Fig. 3 is a method flow diagram of the present invention.We can find out performing step of the present invention substantially in Fig. 3, and each step of this flow chart and each subhead of our back are one to one substantially.
(1) a professional controlling platform is set, it can authenticate the user, content play to service node ISN is controlled, and the remote authentication dial-in user service radius protocol that comprises Access_Request message, Access_Response message, Accounting_Request message and Accounting_Response message between professional controlling platform and the service node ISN is carried out adaptive authentication and the expansion of the requirement of chargeing.
Set up a professional controlling platform, service node and professional control are separated, concrete business is undertaken by service node, and control, authentication, the charging of content play are undertaken by professional controlling platform.Realization about this platform has been the content that those skilled in the art knew at present, and in fact this platform had been applied to service quality control field, service distribution ability field before the present invention.
Can see the residing position of professional controlling platform in Fig. 4, it can add the multicast group to the user and carry out purview certification, and the broadcast of multicast content is controlled, and the multicast user is provided the function of charging by network equipment use and content.Compare with the authentication of User Manager User Manager in second kind of scheme that prior art is mentioned, authentication of the present invention is more tight, it is not initiatively to be initiated, gone authentication to designated user manager UserManager according to the information of authentication position automatically by client software by user terminal, but when the user after the service node request adds multicast, service node is forced to professional controlling platform authentication.In second kind of scheme, also mention multicast management device MulticastManager, it also has management function, but only limiting to the management of the content aspects such as issue of the determining of channel content, channel, still is different with the said here control and management to content play.
Communicate by the remote authentication dial-in user service radius protocol between professional controlling platform and the service node ISN.For the requirement of adaptive authentication and charging, in this step, the remote authentication dial-in user service radius protocol between professional controlling platform and the service node ISN need be carried out following expansion:
I, newly open up a multicast group Multicast-IP parameter, show the user will watch the program of which group for Access_Request message and Access_Response message in the remote authentication dial-in user service radius protocol;
Ii, newly open up a multicast group Multicast-IP parameter and the Start parameter that begins to charge, the Stop parameter that stops to charge, show that respectively the program to which group charges, begins and stops to charge for the Accounting_Request message in the remote authentication dial-in user service radius protocol and Accounting_Response message.
Several message above-mentioned is to have for a long time in the remote authentication dial-in user service radius protocol, and its parameter can be expanded, and we have just newly opened up several parameters for message.
(2) when the user after service node ISN request adds multicast, service node is to professional controlling platform authentication, authentication success duplicates broadcast contents to the user, authentification failure does not then duplicate broadcast contents.
This step has two kinds of situations.First kind is that service node directly multicasts to the user.Fig. 5 is the thread figure that service node directly multicasts to user's controlled multicasting flow process, and on the top of Fig. 5 as can be seen, implementation step is:
B1, user side software startup, multicast server Multicast Server delivers to the user side interface to programme.
B2, user add certain channel by clicking to service node ISN request.
B3, service node ISN send the Access_Request message that has user name User-Name, user cipher User-password, multicast group Multicast-IP parameter to professional controlling platform, and professional controlling platform authenticates parameter.
Wherein, multicast group Multicast-IP parameter is the spreading parameter that we define in (1).The process of authentication mainly is whether whether meeting of seeing user name User-Name, user cipher User-password and user register, user have the right to watch selected channel.
B4, professional controlling platform have the Access_Response message of user name User-Name, user cipher User-password, multicast group Multicast-IP parameter to service node ISN loopback, this message is that authentication success duplicates broadcast contents to the user to the response of Access_Request message.
Second kind is that service node arrives the user through Layer 2 Multicast.Fig. 6 is that service node is through the thread figure of Layer 2 Multicast to user's controlled multicasting flow process.On the top of Fig. 6 as can be seen, the difference of it and first kind of situation is:
In step b2, the user adds certain channel to the Layer 2 Multicast device request earlier, should be asked to service node ISN transparent transmission by Layer 2 Multicast equipment then, and in first kind of situation, the user directly asks to service node ISN.
In step b4, professional controlling platform is behind service node ISN loopback Access_Response message, service node ISN is transmitted to Layer 2 Multicast equipment to this message, duplicate broadcast contents by Layer 2 Multicast equipment to the user, and in first kind of situation, service node ISN is directly to user's broadcast contents.
(3) service node ISN charges to professional controlling platform request after the user duplicates broadcast contents.
This step can clearly be seen that at the middle part of Fig. 5 and Fig. 6, and it specifically comprises such process:
C1, by service node ISN send to professional controlling platform have user name User-Name, user cipher User-password, multicast group Multicast-IP, the Accounting_Request message of the Start parameter that begins to charge, professional controlling platform begins to charge.
Wherein, latter two parameter is the parameter that we expand in (1), and the Start parameter that begins to charge is a Boolean variable, has only 0 and 1 two value, when detecting this parameter and be 1 this channel of user capture with this user name, this password is chargeed.
C2, by professional controlling platform to service node ISN loopback have user name User-Name, user cipher User-password, multicast group Multicast-IP, the Accounting_Response message of the Start parameter that begins to charge, it is the response to above-mentioned Accounting_Request message.
(4) user finishes to watch, and is stopped to charge to professional controlling platform request by service node ISN, and stops to user multicast.
Directly multicast under user's the situation at first kind of service node, shown in Fig. 5 bottom, it specifically comprises:
D1, user finish to watch, and user side software sends the message of leaving the multicast group to service node ISN.
D2, by service node ISN send to professional controlling platform have user name User-Name, user cipher User-password, multicast group Multicast-IP, the Accounting_Request message of the Stop parameter that stops to charge, professional controlling platform stops to charge.
Wherein, latter two parameter is the parameter that we expand in (1), and the Stop parameter that stops to charge is a Boolean variable, has only 0 and 1 two value, this channel of user capture with this user name, this password is stopped to charge when detecting this parameter and be 1.
D3, by professional controlling platform to service node ISN loopback have user name User-Name, user cipher User-password, multicast group Multicast-IP, the Accounting_Response message of the Stop parameter that stops to charge, this message is to the response of Accounting_Request message, stops to user multicast then.
Second kind of service node through Layer 2 Multicast under user's situation, be with the difference of first kind of situation:
In steps d 1, user side software sends to Layer 2 Multicast equipment earlier and leaves multicast group message, and Layer 2 Multicast equipment is to this message of service node ISN transparent transmission then, and is directly to send this message to service node ISN under first kind of situation.
In steps d 3, stop to user multicast by Layer 2 Multicast equipment, and under first kind of situation, be to stop to user multicast by service node ISN.Like this, we have just finished the controlled multicast of service node ISN one time.
