Below by drawings and Examples, the technical scheme of the embodiment of the invention is described in further detail.
Fig. 1 is the flow chart of the implementation method of the embodiment of the invention one session management.As shown in Figure 1, present embodiment specifically comprises the steps:
Specifically, behind the starting up of terminal, initiate register requirement, finish registration to network; After succeeding in registration, terminal equipment is initiated SIP according to man-machine interaction to the video frequency program of appointment and is invited (INVITE) message, perhaps, the programme information of watching when terminal equipment shut down according to individual subscriber preference information or user last time, initiate sip invite message to the video frequency program of appointment voluntarily, the request URI (Request-URI) of this sip invite message can be service identification or channel identication or the program identification of IPTV; Perhaps, after succeeding in registration, also can network side according to user signing contract information and user service data etc., initiate the request of SIP initial session to terminal, after for example the IPTV service server is received third party SIP request, the programme information of watching when shutting down last time according to individual subscriber preference information or user is initiated the request of SIP initial session to the video frequency program of appointment.
The SDP descriptor of carried terminal in this sip invite message is used for describing request and sets up Streaming Media passage and/or more than one signalling path.Wherein, the bandwidth on demand resource of Streaming Media passage is the professional required maximum resource value of user's signed IPTV, for example, television channel A needs the 2M bandwidth, high-definition movie channel B needs the 6M bandwidth, if user's signed IPTV business only comprises television channel and high-definition movie channel, then required maximum resource value is 6M; An above signalling path is used to transmit the signaling message of application layer protocols such as SIP, HTTP, RTSP, can transmit these signaling messages in a signalling path, also can transmit these signaling messages in different signalling paths.In the present embodiment, the relevant signaling message of SIP session does not transmit in an above-mentioned above signalling path, only between terminal and particular network side apparatus, transmit specific SIP signaling message in the SIP signalling path, as between terminal and IPTV state server, transmit SIP notification message (SIP NOTIFY), SIP give out information (SIP PUBLISH) wait the SIP signaling message relevant with presenting business.Further, above-mentioned Streaming Media passage and signalling path can ask to set up in a SIP session, also can ask to set up in different SIP sessions.
After network receives sip invite message,, reserve required maximum resource value corresponding bandwidth resource according to the professional required maximum resource value of user's signed IPTV.After this, after the SIP initial session was set up, the video frequency program of appointment transmitted in the Streaming Media passage, and the user watches video frequency program.
If do not ask video frequency program in the request of SIP initial session, then above-mentioned SIP initial session has been set up the Streaming Media passage of " sky ", i.e. this SIP initial session resource bid of only having carried out the Streaming Media passage takies.
For example, in the step 102, the user is watching a direct broadcast band, and in the step 103, a high-definition movie program is watched in request, because terminal has taken the resource of Streaming Media passage by the professional needed maximum bandwidth resource value application of user's signed IPTV in the SIP initial session, therefore, only need carry out being redirected of SIP session, revise the SDP descriptor, make terminal and high-definition movie program source address set up session connection and get final product, the Streaming Media passage that terminal has been applied for takies resource and is reused.
In addition, the Streaming Media passage of terminal to apply takies resource can also transmit more than one video frequency program simultaneously, as picture-in-picture or mosaic service etc., as long as all required bandwidth of video frequency program are no more than and reserve occupied bandwidth, such as, the user is watching a direct broadcast band, used the 2M bandwidth in the reserved resource, the little picture of another new direct broadcast band is watched in request now, only need carry out being redirected of SIP session, in SDP, increase the medium line description information of new direct broadcast band, and use the remaining bandwidth in the reserved resource.
For another example, user's switching channels, terminal sends the SIP PUBLISH by the signalling path of having set up to the IPTV state server.
Present embodiment is after receiving resource reservation request message, reserve required maximum resource value corresponding bandwidth resource, rather than according to the situation bandwidth resource of current practical application, make all kinds of video frequency programs that the user watched to use the bandwidth resources of having reserved, reduced the time of resource re-negotiation, reduce the time delay that the user watches video frequency program, improved user experience.
Use terminal to watch the IPTV program to be example with IPTV user below, further introduce the technical scheme of the embodiment of the invention.
Fig. 2 is the signaling process figure of the implementation method of the embodiment of the invention two session managements.In the present embodiment, behind the starting up of terminal, at first show the program of television channel A to the user, after this, the user changes platform, requires to watch high-definition movie channel B.As shown in Figure 2, present embodiment specifically comprises the steps:
Step 201, starting up of terminal and finish registration after, obtain the start default broadcast program information;
Behind the starting up of terminal, initiate register requirement, finish registration to IMS equipment; The programme information of watching when shutting down last time according to individual subscriber preference information or user obtains the information of the default broadcast program of start (television channel A), and the information of obtaining the default broadcast program of start in this step can be by following three kinds of modes:
Mode one: terminal is preserved the information of broadcast program when shutting down last time, and broadcast program is as the default broadcast program of start in the time of will shutting down last time, and in the present embodiment, broadcast program was television channel A when terminal was shut down last time, and then terminal is preserved the information of television channel A;
Mode two: network equipment is preserved the information of broadcast program when shutting down last time, and as television channel A, terminal is obtained the information of television channel A from network equipment, with television channel A as the default broadcast program of start; For example, network equipment will be started shooting the information of default broadcast program as User IP TV business datum, after terminal is finished registration, renewal situation to network equipment booking reader IPTV business datum, network equipment sends the update notification of User IP TV business datum to terminal, terminal is obtained the User IP TV business datum of renewal, thereby obtains the information of television channel A;
Mode three: network equipment generates the information of the default broadcast program of start according to the individual subscriber preference information, and terminal is obtained the information of the default broadcast program of start from network equipment; For example, network equipment is according to the individual subscriber preference information, judges user's match of liking watching the football game, when starting up of terminal, the just in time live football match of television channel A, then with television channel A as the default broadcast program of start.
Above-mentioned network equipment can be the IPTV service server, also can be other equipment of network side.
Step 202, terminal initiate to comprise first conversation request (the present embodiment conversation request is specially sip invite message) of the identification information of the default broadcast program of start shooting to network (present embodiment is specially IMS equipment), and the request unified resource in first sip invite message identifies the identification information that is television channel A;
In this first sip invite message, can carry indication information according to required maximum resource value bandwidth resource, indication is applied for bandwidth resource according to the professional needed maximum resource value of signed IPTV, for example, in the SDP descriptor, except the medium type (being the medium type of television channel A correspondence) of describing the current sessions practical application, also describing the professional corresponding medium type of IPTV of required maximum resource value, is the medium type of high-definition movie channel B correspondence in the present embodiment.Perhaps, in this first sip invite message, also can not carry indication information according to required maximum resource value bandwidth resource.
Step 203, first session of IMS device processes according to first sip invite message, send resource reservation request message;
After IMS equipment receives first sip invite message, send resource reservation request message to RACS, can be specially: as if the indication information that has carried in first sip invite message according to required maximum resource value bandwidth resource, then IMS equipment sends Diameter message to RACS, can carry indication information in this Diameter message according to required maximum resource value bandwidth resource, for example, the professional corresponding medium type of the IPTV of required maximum resource value is carried in the Diameter message; Perhaps, if do not carry indication information in first sip invite message according to required maximum resource value bandwidth resource, then IMS equipment sends Diameter message to RACS, does not carry the indication information according to required maximum resource value bandwidth resource in this Diameter message.
Step 204, RACS receive resource reservation request message, according to this resource reservation request message, obtain required maximum resource value;
If carried the indication information according to required maximum resource value bandwidth resource in the resource reservation request message, the professional corresponding medium type of the IPTV of promptly required maximum resource value then obtains the required maximum resource value of this medium type correspondence;
If do not carry indication information in the resource reservation request message according to required maximum resource value bandwidth resource, it is the medium type that has only carried current sessions practical application (television channel A) in the resource reservation request message, then RACS is according to the user signing contract information that obtains from user-subscribed database, know the IPTV business of the required maximum resource value that the user has contracted, and obtain required maximum resource value.
Step 205, the required maximum resource value corresponding bandwidth resource of reservation;
Step 206, RACS return the resource reservation response message to IMS equipment;
Step 207, a SIP session are set up successfully, and terminal receives the corresponding streaming medium content of the default broadcast program of start (television channel A);
Step 208, user change platform, and the program of high-definition movie channel B is watched in request, and terminal is obtained the information of update playing program, and this update playing program is high-definition movie channel B;
Step 209, terminal comprise that to the initiation of IMS equipment the SIP of the identification information of update playing program is redirected invitation message, and it is that a SIP is redirected invitation message (i.e. the redirected invitation message of a SIP session) that this SIP is redirected invitation message; Wherein asking URI is the identification information of high-definition movie channel B;
Be redirected in the invitation message at a SIP, SDP describes the medium type of current sessions practical application, and be the medium type of high-definition movie channel B correspondence this moment; Further, a SIP is redirected the indication information that can also comprise resource reuse in the invitation message, and indication is reused a SIP and is redirected the SIP reserved resource that session is applied for that invitation message has been set up.
Step 210, IMS equipment are redirected invitation message according to a SIP, send resource reservation request message;
If a SIP is redirected the indication information that has comprised resource reuse in the invitation message, then can comprise the indication information of resource reuse in this resource reservation request message;
Step 211, RACS receive resource reservation request message, according to this resource reservation request message, reuse the bandwidth resources of having reserved;
If comprised the indication information of resource reuse in this resource reservation request message, then RACS reuses the bandwidth resources of having reserved according to this indication information; If there is not the indication information of resource reuse in this resource reservation request message, then RACS is according to the current sessions application feature, as judges that reserved resource satisfies the medium type of current sessions practical application, then reuses reserved resource.
Because in step 205, the bandwidth resources that RACS reserves are the professional corresponding bandwidth resource of IPTV that needs the maximum resource value, promptly, applied for that reserved resource satisfies the current sessions resource reservation request, the bandwidth resources of then having reserved are reused, and use the resource occupation of the session of reserved resource (watching television channel A) to be cancelled originally; For example, in step 205, RACS according to the professional required maximum resource value application of user's signed IPTV the 6M bandwidth, watching the session of television channel A to take resource is the 2M bandwidth, then in this step, the 6M bandwidth resources of having reserved will be shared by high-definition movie channel B.
Step 212, RACS return the resource reservation response message to IMS equipment;
Step 213, SIP are redirected successfully, and terminal receives the streaming medium content of update playing program correspondence.
Present embodiment is after starting up of terminal and registration, maximum resource value according to signatory IPTV service needed goes to apply for bandwidth resource, rather than according to the situation bandwidth resource of current practical application, make all kinds of video frequency programs that the user watched to use the bandwidth resources of having reserved, reduce the time of resource re-negotiation, reduced the time delay that the user watches video frequency program; Further, terminal equipment does not need user's man-machine interaction can initiate the SIP session invitation request voluntarily after finishing start-up logging, has further reduced the time delay that the user watches video frequency program.
