Step 200 receives the pre-recording request message that the user sends, and described pre-recording request message comprises the program identification of target program and/or the beginning and ending time of described target playing programs;
UE sends the pre-recording request by IMS CORE or SSF to SCF, and SCF receives this pre-recording request.Then, SCF does to add a processing to the number of times of quoting of target program correspondence, receives this pre-recording request with sign.
Step 201 in the scheduled time before the target playing programs, is obtained target program corresponding recording state and is quoted number of times;
SCF can start a timer before the target program begins to play, play countdown.Start-up time can be pre-set.After timer starts, SCF will search the recording state of target program and quote relevant information such as number of times in listing in the scheduled time before broadcast, if know that to quote number of times non-vanishing, and the corresponding recording state is still unrecorded first state information of expression, then send to MF and record Indication message, MF just can carry out performance recording according to the beginning and ending time of the program identification of recording the target program that comprises in the Indication message and/or target playing programs.Though if know that to quote number of times non-vanishing, the corresponding recording state is not first state information, before then being described, this program has been requested to record, and this need not to record once more.
SCF knows that the user asks recorded program to satisfy to MF and sends the condition of recording Indication message in the scheduled time before playing programs, then records indication request to the MF transmission and carries out performance recording.
In the network individual recording method that present embodiment provides, not only can satisfy the request of user's pre-recording, but also avoid repeating to record by the recording state of program, saved the storage resources of network side effectively, realize the management in user network space by the mapping of Virtual Space and physical space, improve QoS.
In the various embodiments described above, comprise that also SCF is after recording Indication message to the MF transmission, target program corresponding recording state in the listing is updated to the step of second state information that expression recording, in MF carries out the process of performance recording, repeats to record avoiding.After MF records successfully, to return the response of recording success to SCF, SCF is updated to the third state information that expression has been recorded with the target program corresponding recording state in the listing after receiving the response of recording success that MF returns, record to avoid follow-up the repetition.MF can realize the corresponding a plurality of users' of a physical store virtual memory effectively by the recording state that program is set in different phase.
In the various embodiments described above, can also comprise that SCF is after the message of recording request immediately or pre-recording request message of receiving the UE transmission, to verify at first whether the target program allows to record, knowing and verifying again after described target program allows to record whether user's performance recording authority and recording and storing space satisfy recording request through checking, user NPVR cyberspace manages according to the Virtual Space that with space or duration is unit in the embodiment of the invention, be specially and user's NPVR cyberspace can be handled as logical space, but not the actual physical space.The management and the charging that be to keep the user network space realize the management in user network space by " cyberspace product ", the cyberspace Product Definition user's virtual network space and recorded content preserve the term of validity.The cyberspace that Product Definition is represented with capacity or duration, user's overall network space is the cyberspace attribute summation of its all products of ordering.

The embodiment of the invention also provides the mechanism of deletion recording request, and the user, browses the NPVR recording request of having applied for, and can select corresponding registration-cancellation/deletion to record application by platform (Portal) interface from service interface by the set-top box calling party.Wherein " cancellation " is to record at the NPVR that does not record end as yet, and " deletion " is at the NPVR recording request of recording end.When the NPVR of user's process user recorded cancellation/deletion application, the NPVR of related-program quoted number of times and subtracts 1.Deletion NPVR records and is specially, after the cancellation record command or deletion program instructions that receive the UE transmission corresponding to the target program, the number of times of quoting to target program correspondence does to subtract a processing, and when the quoting number of times and be kept to zero of target program correspondence, send the deletion task to MF, with indication MF deletion target program corresponding recording file, after receiving the deletion response that MF returns, target program corresponding recording state is updated to still unrecorded first state information of expression.
Should be noted that if exist related-program to record success but no longer include other NPVR and quote, then issue recorded file deletion task, deletion this document to MF.Can also be included in and be used for representing the database that history is recorded record deletion target program corresponding recording record to the user.Described database is recorded record usefulness for storage user's history, when a program is recorded in user's request, just adds a record in database, when the user logins by platform (Portal) interface, can represent its all history to the user and record record.
The signaling process figure that Fig. 6 records for request deletion NPVR in the network individual recording method of the present invention, present embodiment is to describe to be embodied as example in the conventional IPTV system, as shown in Figure 6, this flow process comprises:
Step 1c, UE send to SSF and record cancellation/removal request;
Step 2c, SSF transmit to SCF and record cancellation/removal request;
Step 3c, after the cancellation/deletion trigger condition that arrives recorded file, SCF sends the cancellation/deletion task of recording to MF;
The deletion trigger condition of described recorded file comprises: the user initiates NPVR and records cancellation or removal request, if the related-program recording task issues; Or SCF starts timer, and detecting the file of recording or having recorded does not have relevant NPVR and quote.
Step 4c, the record of being correlated with in the SCF delete database;
Step 5c, MF carries out the cancellation/deletion task of recording, the deletion recorded file.
Fig. 7 is the signaling process figure of NPVR content stores in the network individual recording method of the present invention and scheduling, and present embodiment is to describe to be embodied as example in the conventional IPTV system, and as shown in Figure 7, this flow process comprises:
Step 1d, SCF sends the performance recording request and sends to Centroid MF;
Step 2d, Centroid MF carries out recording task;
Center MCF sends the performance recording order to center MDF, and center MDF adds multicast and carries out performance recording;
Step 3d, Centroid MF push (Push) partial document content in advance to edge nodes MF.
In the present embodiment, under the MDF classification deployment scenario, center MDF records portion, and pushes (Push) partial document content in advance to edge MDF.When recorded program is play in the UE request, the edge MDF that determines according to dispatching principle nearby at first plays the center MDF partial content that send in advance, program corresponding recording file that receives recording request message to UE, adopts then while playing and provides service from the mode of center MDF download for UE.
In order to prevent the reservation in indefinite duration of user NPVR recorded content and cause increasing without limitation of system side storage that MF formulates the aging strategy of NPVR recorded content, regularly deletes the content of edge and region junction.If if the NPVR content surpasses deletion by hand of user after the term of validity, then system is provided with it automatically for losing efficacy, and deletion corresponding recording file.
Fig. 8 asks to handle schematic diagram for network individual recording method of the present invention more, all NPVR program recordings are only preserved portion in service end, a plurality of users are to the same physical file of the equal correspondence of recording of same program, therefore, be not that all user's recording request all are handed down to MF, it is the number of times of quoting that upgrades related-program that user request is recorded, and follow-up SCF will have user's recorded program to be issued to MF according to the NPVR request situation of program to record.SCF to the solution thinking of many requests is: when user's request is recorded immediately, if current program issues do not record, then SCF issues recording task immediately to MF, and startup is recorded.If certain program that does not begin as yet is by pre-recording or be included in immediately in the recording request, then several minutes (configurable) issues recording task to MF before program begins, and MF starts according to request on time and records.When user applies deletion NPVR recording request, if recording task issues, and the relevant program NPVR that no longer includes other records and quotes, and then issues recorded file deletion task to MF, the deletion recorded file.SCF detects the program of having recorded success but not had NPVR to record to quote when not busy, and send file deletion task to MF, deletion corresponding recording file, promptly, SCF has the third state information of corresponding recording state for representing to have recorded when detecting, and the corresponding number of times of quoting is zero program, illustrate that this performance recording is abnormal conditions, then send the deletion task, with indication MF deletion program corresponding recording file to MF.
