Technical field

The present invention relates to the field of communications, and in particular, to a method and a device for setting a temporary right, and a method, system and device for implementing a friend television service.

Background technique

IPTV (Internet Protocol Televisor, IP TV) Internet TV is a video and audio service that can be received by mobile phones, televisions, and computer terminals through a controllable managed wired or wireless network. At present, there is a trend of continuous convergence of IPTV systems and communication systems. The terminal can watch live or on-demand programs through terminal devices such as mobile phones, and many unique converged services are born accordingly. A friend push is one of them. It is to invite a friend to watch a program or channel together.

In the current IPTV system, if a terminal such as STB (Set Top Box) wants to watch live programs, it must first go to the IPTV middleware to authorize, and then pass the DSLAM ( Digi ta l Subscr iber Line Acces s). Mul t iplexer, data terminal line access multiplexer) and other multicast groups of access devices to obtain live media streams. In an access device such as a DSLAM, the terminal is authorized to determine the terminal through the terminal permission template.

In addition, the IPTV based on the IP Multimedia Subsystem (IMS) refers to the implementation of the IPTV service through a specific application server (AS, Application Server) based on the IMS network architecture. This is a product that combines communication services and IPTV services in pursuit of business integration. After the integration of the IPTV service and the communication service, the concept of the friend TV is generated. The friend TV means that the user who is watching the IPTV TV program invites other users to watch the TV through the communication network. A value-added service for the show. In the friend TV service, the communication and media play of the inviting user and the invited user are completed through the IMS network, which greatly facilitates the use of the user, and also facilitates the unified billing and unified management of the operator.

In the traditional IPTV service, the user first needs to open an account, obtain the rights of the IPTV service, and then perform on-demand (VOD, Video On Demand) or live program viewing.

The inventor found in practice that when the IPTV service and the communication service are merged, if the IPTV terminal A invites the IPTV terminal B that has not ordered the program to watch the program, or an IPTV terminal invites a friend who is not the IPTV terminal to watch a certain For the program, the access device may refuse to join the multicast group to watch the live program because the push terminal does not have its permission template or has no permission.

The existing friend TV service is actually a process of inviting the user to send an invitation message carrying the on-demand program identification to the invited user, and then invites the user to watch the on-demand program instructed by the user. When the invited user does not have the IPTV service right or does not have the right to invite the on-demand program indicated by the user, the friend TV service cannot be implemented; in addition, when the invited user has the business right, even if the friend business can be realized, the fee is recorded. On the account of the invited user, the meaning of "invitation" cannot be truly reflected.

Step 3: The terminal 1 requests the rights management device to authorize the terminal 2;

The specific implementation may be that after receiving the 200 0K message, the terminal 1 considers that the terminal 1 has accepted the invitation, and sends the first notification message INF0 (or message sage) to the rights management device (where the rights management device may be an IPTV middleware device), requesting The rights management device authorizes the user 2; wherein the first INF0 (or message sage) message may carry the information of the terminal 1, the information of the terminal 1, the service identifier (used to indicate that the friend pushes the service), the program identifier, and the like. .

Step 4: The rights management device determines that the terminal 2 does not have the corresponding authority, and notifies the access device to which the terminal 2 belongs to add temporary rights for the terminal 2;

The specific implementation may be a rights management device, such as a middleware device in the IPTV. After receiving the first INF0 (or message sage) message, it is first determined according to the user data whether the terminal 1 subscribes to the program to be pushed and whether there is a friend. Push permission; if one of the conditions is not satisfied, step 11 is performed; if the terminal 1 subscribes to the program to be pushed and has the right to push the friend, And determining, according to the user data, whether the terminal 2 carried in the first INFO message is an IPTV terminal, and if the terminal 2 is an IPTV terminal, determining whether the terminal 2 has the right to view the program. If the terminal 2 has the right to view the program to be pushed, step 6 is performed; since it is assumed in the embodiment that the terminal 1 does not have the right to view the live program, the rights management device carries according to the first notification message. The information of the terminal 1 determines an access device to which the terminal belongs, such as a multicast management node such as a DSLAM or a Broadband Acces s Server, and sends a user rights refresh message SOAP to the access device, and carries The rights record of the terminal 1 and the information of the temporary rights operation method are used to instruct the access device to add temporary rights to the terminal 2 according to parameters in the SOAP message. In the embodiment of the present invention, the addition, update, or deletion of the temporary permission mentioned may be implemented by adding, updating, or deleting a temporary permission template.

As an implementation manner of the embodiment of the present invention, this step may be implemented by the rights management device in the embodiment of the rights management device, that is, by the receiving unit, the determining unit, and the sending unit in the rights management device. The receiving unit receives the first notification message INFO (or message sage) sent by the terminal 1, and the determining unit determines, according to the information of the terminal 2 in the first notification message, the access device to which the terminal 1 belongs. The sending unit sends a SOAP message to the access device, and carries the permission record of the terminal 2 and the information of the temporary permission operation method, and is used to indicate that the access device is the terminal according to the parameter in the SOAP message. Increase temporary permissions.

Step 5: The access device to which the terminal 2 belongs adds temporary permission to the terminal 2, and returns a temporary permission increase success message to the rights management device.

The specific implementation may be that after the access device to which the terminal 2 belongs receives the SOAP message sent by the rights management device, the temporary terminal authority is allocated to the terminal 2 according to the operation specified in the SOAP message, and the validity period may be set. Generally, the access device may be configured. The setting is valid for one day, but may be specifically set according to the specific situation, which is not limited by the embodiment of the present invention; after the temporary authority is successfully set, the access device returns to the rights management device (such as the middleware of the IPTV). 200 0K message, and carry the permission operation result.

The embodiment of the present invention does not limit the entity that sets the expiration date. In a specific implementation, The rights management device separately controls the time for assigning the temporary permission to the terminal 1, and the time for the temporary device to be set by the access device may be controlled by the rights management device, or the time for the temporary permission may be set by other devices. The rights management device controls; deleting the temporary rights after the temporary rights expire.

As an implementation manner of the embodiment of the present invention, this step may be implemented by the transceiver unit and the setting unit in the access device embodiment, that is, the transceiver unit acquires the SOAP message and carries the rights of the terminal 2 Recording and information of the temporary permission operation method; the setting unit adds temporary permission to the terminal 2 according to the authority record in the message and the information of the temporary authority operation method.

Step 6: The rights management device sends a notification message to the terminal 2, informing it that the node destination address and the service indication are to be played;

The specific implementation may be that the rights management device receives the result returned by the access device, determines that the temporary permission setting is successful, and sends a second notification message to the terminal 1 to carry the play address and the service indication of the push program; If the setting fails, go to step 11.

As an implementation manner of the embodiment of the present invention, the step may be implemented by the rights management device in the embodiment of the rights management device, that is, the control unit sends a second notification message to the terminal 1 to carry the message. Push the play address and service instructions of the program.

Step 7: The terminal 2 requests the access device to join the multicast group according to the indication;

The specific implementation may be that the terminal 2 receives the second notification message mesage sent according to the rights management device, performs media negotiation with the media control server, and then sends a request to the access device to join the multicast group message, such as IGMP (Internet). Group Management Protoco l ) jo in message, request to join the multicast corresponding to the live program.

Step 8: The access device plays the requested program to the terminal 1;

The specific implementation may be that the access device determines that the terminal 2 has the right to view the pushed program according to the temporary permission set by the access device, and adds the terminal 2 to the corresponding multicast group, so that the terminal 2 The pushed program can be viewed. Step 9: The rights management device periodically checks whether the temporary permission of the terminal 2 is expired according to a preset time limit, and if the temporary right expires, sends a second SOAP message to the access device to which the terminal 1 belongs, carrying The permission record of the terminal 2 and the permission operation method, here refers to deleting the specified permission record;

Step 10: After receiving the second SOAP message, the access device to which the terminal 2 belongs deletes the temporary permission of the terminal 2 to view the specified program according to the operation method and the permission record.

Step 11: The rights management device returns a push program failure message to the terminal 1 and carries the failure reason.

The foregoing method embodiment may also be implemented in an IMS system, where the rights management device corresponds to an application server AS (Application Server), and the AS determines the user authority; the access device is in resource control. The user temporary permission is set under the control of the subsystem RACS (Resource and Admission Control Function), and the media control function entity controls the completion of the media negotiation, and the GPRS (General Packet Radio Service) supports the GGSN (Gateway GPRS Support Node) or The DSLAM adds User 2 to the multicast corresponding to the live program. In the foregoing method, the access device, such as the DSLAM, the BAS, and the RACS, can not only complete the addition and setting of the temporary permission of the user, but also complete the operation of updating and deleting the temporary permission of the user; Let me repeat.

FIG. 4 is a flowchart of a method for implementing a friend television service according to an embodiment of the present invention. As shown in Figure 4, the following steps are included:

Step 301: The IPTV AS receives the friend TV service invitation that carries the authentication information of the inviting terminal. And, the friend television service is authenticated according to the authentication information of the invited terminal.

Step 302: After the authentication succeeds, the interactive network television application server notifies the access device to which the invited terminal belongs to add temporary permission to the invited terminal; and, the central media server receives the friend television service request message. Specify an edge media server for the invited terminal.

Step 303: The invited terminal acquires an address of the specified edge media server, and obtains a friend television program from the edge media server according to the address.

Through the method shown in FIG. 4, the friend TV service can also be implemented when the invited user does not have the IPTV service right.

In order to make the objects, technical solutions and advantages of the present invention more clear, the following uses the user A and the user B in the IMS network architecture as an example, and further describes the present invention by using the embodiments shown in FIG. 5, 6, and 7. When accessing the IMS domain, the network side has authenticated user A and user B, user A has the IPTV service authority, and user B has only the communication authority in the IMS domain, that is, user B has no IPTV service authority; A invites user B to join the friend TV service. The terminals used by user A and user B are terminal A and terminal B, respectively, and terminal A is the inviting terminal, and terminal B is the invited terminal.

FIG. 5 is a flow chart of a first embodiment of a method for implementing a friend television service in an IMS network architecture according to the present invention. As shown in Figure 5, the following steps are included:

Step 401: User A is watching an on-demand program, that is, there is streaming media transmission between terminal A and edge server A that is closer.

The edge server is a Media Resource Function (MRF) network element in the IMS network.

Step 402: User A invites user B to watch the current on-demand program, and terminal A sends a friend TV service invitation message to terminal B, which carries the authentication information of terminal A. The friend TV service invitation message may specifically be an "Invi te" message or a "Mes sage" message. In the embodiment, the "Invi te" message is taken as an example. In the Reque st UR I, header field or Bo dy of the "Invi te" message, it is identified as a friend TV service, and in the "Invi te" message. User carrying A in IPTV Authentication information in the service, including the username and password. When a friend TV service is identified in the header field of the "Invite" message, the part of the header field described in the SIP protocol needs to be extended.

In this step, the terminal A pushes the friend TV service invitation message, that is, the "Invite" message, to the terminal B, and the terminal B may be a terminal having a streaming media playing function such as a mobile phone or an STB. The "Invite" message sent by terminal A to terminal B is sent to terminal B through the Call Session Control Function (CSCF, Call Session Control Function). The CSCF here includes the CSCF of the area where the terminal A is located and the CSCF of the area where the terminal B is located.

In this step, in order to prevent user B from obtaining the password of user A, the password carried in the "Invite" message is a string of the real password and time stamp of user A processed by the MD5 algorithm or other irreversible encryption algorithm. At the same time, in the "Invite" message, the timestamp used by the encryption algorithm is also required, so that when the user B requests the authentication from the IPTV AS, the IPTV AS can pair the encrypted characters according to the timestamp and the known password of the user A. The string is verified. That is, when the password of the user A is not known by the user B, the authentication information of the user A includes: the user name of the user A, the timestamp, and the character string obtained by the encryption algorithm after the password and time stamp of the user A are processed.

In this step, the "Invite" message may also carry the time information of the program viewed by the user A, so that the user B can simultaneously watch.

Step 403: After receiving the "Invite" message of the user A, the user B sends an "Invite" message to the IPTV AS based on the IMS network, and the user name and password of the user A are carried in the "Invite" message. And identify user B as the invited user.

In this step, the "Invite" message sent by the terminal B to the IPTV AS is sent through the CSCF in the area where the terminal B is located.

Step 404: After receiving the "Invite" message, the IPTV AS authenticates the user B, and uses the user name and password of the user A carried in the "Invite" message.

Step 405: After the authentication is passed, the IPTV AS notifies the access device to which the terminal B belongs to add the temporary permission to the terminal B. Moreover, the IPTV AS returns a "2000K" message to the terminal B, where the address of the central media server is carried. In this embodiment, the central media server is a central media server (VOD AS) of the on-demand service. In this step, the "200 0K" message sent by the IPTV AS to the terminal B is sent through the CSCF in the area where the terminal B is located.

After the access device adds the temporary permission to the terminal B, the terminal B can smoothly obtain the streaming media service from the central media server and the edge media server through the access device.

Step 406: The terminal 200 sends a "200 0K" message to the terminal A to notify the acceptance of the invitation. Step 407: The terminal B sends a friend television service request message requesting the program to the central media server, and the message may also be implemented by using an "Invi te" message, and carrying the identification information of the terminal B in the header field or the body of the "Invi te" message. , such as the IP address of the terminal B or the session initiation protocol uniform resource identifier (SIP URI) of the terminal B, and the like.

In this step, the "Invi te" message may be a Session Initiation Protocol (SIP) message or a Real Time Streaming Protocol (RTSP) message, depending on the central media server. Types of.

Step 408: The central media server allocates an edge media server B that is closer to the terminal B according to the identification information of the terminal B, and brings the address of the edge server to the terminal B by using a “200 0K” message.

Step 409: The terminal B establishes a media connection with the edge server B according to the received address. In this step, the terminal B may send the time information of the program viewed by the user A obtained in step 402 to the edge media server in the process of establishing a media connection with the edge media server B.

B.

Step 410: The terminal B acquires the friend television program from the edge server B, that is, the edge media server B transmits the streaming media of the friend television program to the terminal B.

In this step, the edge media server B sends the streaming media to the terminal B according to the time information of the program viewed by the user A sent by the terminal B, and the user B and the user A simultaneously watch the television program.

So far, the flow of the first embodiment of the method for implementing the friend TV service under the IMS network architecture is completed. In this embodiment, when the invited user does not have the IPTV service right, the friend TV service can also be implemented. In addition, after the authentication information of the inviting terminal is authenticated, the cost of the friend's television service is recorded on the account of the inviting user, which truly reflects the meaning of the "invitation". In addition, in the prior art, the central media server allocates the edge media server using the principle of "who authenticates, and the assigned edge media server is closer to". Therefore, when the buddy service is implemented by using the method shown in FIG. 4, the edge terminal server that is closer to the inviting terminal is allocated to the invited terminal. At this time, if there is a big difference between the physical location of the inviting terminal and the invited terminal, that is, when the invited terminal is far away from the inviting terminal and the allocated edge media server, the transmission delay and the transmission loss are also greatly increased. Therefore, in the embodiment of the present invention, the invited terminal is further allocated a neighboring edge server according to the identification information of the invited terminal, so that the invited terminal can obtain a better quality of service in the friend television service.

The above process shown in Fig. 5 not only enables the user B without the IPTV service authority to accept the friend TV service invitation, but also ensures the quality of the user B viewing the program.

6 is a flow chart of a second embodiment of a method for implementing a friend television service in an IMS network architecture according to the present invention. As shown in Figure 6, the following steps are included:

Step 501 ~ step 502, the same steps 401 ~ 402.

Step 503: After receiving the message that the user A is an "Invi te" message, the user B sends an "Invi te" message to the IPTV AS based on the IMS network, and the "Invi te" message carries not only the user A's. The user name and password also carry the identification information of the terminal B, and identify the user B as the invited user.

Step 504: After receiving the "Invi te" message, the IPTV AS authenticates the user B, and uses the user name and password of the user A carried in the "Invi te" message.

Step 505: After the authentication is passed, the IPTV AS notifies the access device to which the terminal B belongs to add the temporary permission to the terminal B. The IPTV AS sends an "Invi te" message requesting the friend's TV service to the central media server, where the message carries the terminal. B identification information.

After the access device adds temporary rights to terminal B, terminal B can successfully pass the access device. The central media server and the edge media server obtain streaming media services.

Step 506: The central media server allocates an edge media server B that is closer to the terminal B according to the identification information of the terminal B, and brings the address of the edge server B to the IPTV AS by using a "200 0K" message.
