Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of implementation method and equipment of recoding service.
Background technology
N-PVR (Network Personal Video Recorder, network side individual recording) refers at the network side memory space certain for the user distributes, the media content that comes recording user to record by network, and play these media contents according to user intention.Wherein, the source of the media content that record can be a broadcast program, also can be request program etc.
This business can be brought following benefit for the user for the user:
(1) off-line storage of user terminal: when utilizing the N-PVR function to record the content that network side provides, terminal does not need to participate in recording, user even can be in off-mode when recording.Owing to not limited by terminal bandwidth, N-PVR also can help user concurrent and record a plurality of contents.
(2) extended menory of terminal: under the situation of the limited storage space of terminal, can utilize N-PVR to deposit temporarily, at the convenient time shift or watch.
(3) individual shared storage: utilize the individual communal space, can make things convenient for the user utilize different terminals (family, office, or even other people terminal) content of watching favorites.Data only need be preserved portion, and reproducting content everywhere.
In recording process, user's operations such as recording, stop to record or restart to record of can also asking network to be cancelled.
Separation architecture is meant the framework that MC (Media Controller, media controller) and MP (Media Processor, Media Processor) separate, and its schematic diagram as shown in Figure 1.Wherein, MC finishes and records the control deixis, and MP records associative operation according to the indication of MC, and can record reporting of result.Concrete, MC includes but not limited to MSC-Server (Mobile Switch Control-Server, Mobile Switching Center Server), MRFC (Media Resource Function Controller, the media resource controlled function) and MCF (Media Control Function, media control function) etc., medium processing device includes but not limited to MGW (Media Gateway, media gateway), MRFP (MultimediaResource Function Processor, the media resource processing capacity) and MDF (Media DeliveryFunction, media delivery function) etc.
In the prior art, media resource controlled be mainly based on the H.248 control of agreement, H.248 the basic principle of agreement is: be terminal with the various resources on the medium processing device are abstract, terminal is further divided into physical terminal and ephemeral terminations again.Physical terminal is represented some physical entities with semipermanent existence, as TDM (Time Division Multiplex) time slot; The public resource that on behalf of provisional application, ephemeral terminations use the back to discharge flows as RTP (Real-time Transport Protocol, RTP).Combination between the terminal is conceptualized as context, with the topological relation of describing between the terminal.Abstract based on these, call proceeding is actually terminal and contextual operation, finishes by command request between medium control device and the medium processing device and response.
H.248.1 having defined basic bag in H.248.X, is succession and expansion to Ji Bao.Bag is meant that the parameter with professional correlation carries out in logic that polymerization forms, and above-mentioned terminal has realized a subclass of these bags usually.Wherein, the signal description symbol in the bag has comprised the set of signals that requires MP to be applied to terminal, and signal is identified by bag name and signal ID; Event descriptor has comprised that then MP requires the one group of incident that detects and report, this incident is made up of event name and some other optional parameters; The descriptive statistics symbol then is used for describing the SOT state of termination and the use information of a specific context, and MC issues the statistics request to MP usually, and the MP response reports ASSOCIATE STATISTICS information.H.248.9 defined the recording bag in, this bag designs for telephonograph.This bag has been expanded the signal and the incident of basic bag, has realized the function of recording.
Basic recording process may further comprise the steps as shown in Figure 2:
Step s101, MC begin recording by recording bag indication MP.
Carried the relevant parameter of prompt tone in the signal description symbol wherein, as the sign of prompt tone file, the broadcasting speed of prompt tone, the broadcast sound volume of prompt tone etc.Also have some timer parameters, be used for representing duration before the user input voice as timer before the voice, this timer expiry represents that the user does not import voice; Timer is used for representing that user's expression of how long keeping silence finishes input behind the voice, and this timer expiry represents that the user finishes input.Also have some key parameters, be used for representing the operation that the user will carry out when pressing some special key.Show and stop to record that the * key table shows that cancellation records and delete the content of having recorded such as pressing the # key table.
Step s102, MP send response message to MC.
Step s103, MP point out user input voice to user's playing alert tones.
Step s104, user input voice, MP begin to record.
Step s105, user press some special key and operate recording, and record or stop to record etc. as cancellation.
Finish if step s106 records, MP reports the incident of finishing of recording to MC.If record success, can also report the duration of recording.
The inventor finds that there is following shortcoming at least in the realization that media business is recorded in the above-mentioned prior art in realizing process of the present invention:
The user is directly mutual to the control of recording and MP in the prior art, but for the recording of the Media Stream of real-time broadcast, these controls are finished alternately by MC and MP.MC should be able to indicate MP to cancel the operation of having recorded or restart to record, but can't realize in the prior art.And media controller can't initiatively be obtained the statistical information of recording from Media Processor.

Step s605, MC receive the request that recovery is recorded.
Step s606, MC issue the request message that recovery is recorded, recording before indication MP recovers.
Step s607, MC recover original recording, and the response message that transmission is recorded is to MC.
The response message that step s608, MC transmission recovers to record is to operation controlling entity.
In addition, the control that recovers to record can also realize by the following method.Specific descriptions are:
The request message that the MC transmission begins to record recovers to record by the recording mode parameter indication of carrying to MP.Wherein, the parameter value of recording mode is for appending append, and new recorded content will begin from the end of current file to preserve, and append the content back of recording.
In the embodiments of the invention two, the implementation method of each flow process that the foregoing description one is described is elaborated.
Concrete, can expand one and H.248 wrap rec to realize recording function.Need to prove that signal, incident, the name of statistics and the name of parameter in the present embodiment in the name of the bag of each expansion and the bag all are an example, also desirable other names, and be not used in the scope that limits the embodiment of the invention.
The expansion to signal that comprises in this rec bag is as follows:
1) recording request signal record of expansion
This signal is used for the recording medium content, can carry some parameters in the signal:
The sign RecordingIdentifier of recorded content (mandatory parameter): be used to refer to by the physics deposit position of recorded content (position in internal storage).If its value is " $ ", then expression needs MP to distribute this sign.
Recording mode mode (optional parameters): the sign of the recorded content that is used to specify of expression, the preserving type of recorded content can be the recorded contents before covering, and also can be the back of appending at before recorded content, and this parameter is optional.Allow value for covering overwrite and appending append.The duration recduration (optional parameters) that this request is recorded: represent relevantly, pointed out the time length that this request is recorded with current recording request.
The capacity recstorage (optional parameters) that this request is recorded: represent relevant with current recording request, the capacity information of having indicated this request to record.
The storage format format (optional parameters) of recorded file: the storage format of expression file, as 3gp form, wav form etc.
2) cancellation of expansion recording signal cancel
This signal is used for MC indication MP and stops ongoing recording operation, and deletes the content of having recorded.
3) one of expansion restarts recording signal restart
This signal is used for MC indication MP and stops ongoing recording operation, and deletes the content of having recorded, according to the indication of recording request message again, restarts to record.
4) halt signal pause of expansion and recovery recording signal restore
Halt signal is used for MC indication MP and suspends current recording operation;
Recover recording signal and be used for current recording state is converted to by time-out and record, begin to record from current point in time.
In addition, the expansion to incident (event) that comprises in this rec bag is as follows:
1) turkey fail is recorded in one of expansion
By reporting of this incident, the reason that MP records failure with feedback gives that MC, the reason of failure comprise that the MP memory space exhausts, MP internal error etc.
2) incident success is recorded successfully in one of expansion
When recording when completing successfully, MP reports this incident to MC.This incident can be carried some parameters, as:
The result who records (mandatory parameter) comprising: 0: reached the duration that this request is recorded, recorded success; 1: reached the capacity that this request is recorded, recorded success.
The actual duration duration (optional parameters) that records;
The actual file size size that records (optional parameters).
3) content identification of expansion has assigned incident iddetect.If MC indication MP distributes content identification, MP can assign incident by reporting content identification, the sign of the recorded content of feedback allocation.
In addition, the expansion that comprises in this rec bag to statistics (statistic)
1) the actual duration of recording
Be used to add up the duration of this recording request institute recorded content.
2) size of actual recorded content
Be used to add up the size of this recording request institute recorded content.
As shown in Figure 7, use the H.248 realization of expansion to begin to record and record the following description of the control of finishing.Specifically may further comprise the steps:
Step s701, MC receive the request message that begins to record that operation controlling entity sends.
Step s702～s703, finish the establishment of end points: MC uses the ADD order to create end points, MP return response message.
The request message that step s704, MC transmission begins to record is to MP.
Carry the recording request signal of expansion by Modify order H.248, finish the indication of recording request.In this step, if MC has distributed content identification, then the MC parameter that needs will to identify as the recording request signal sends to MP.If MC does not distribute content identification, then the content identification parameter of MC in need the recording request signal is set to " $ ", and MP distributes this content identification with indication.
The use-case of expanding packet rec is:
Signals{rec/record{RecordingIdentifier＝＂$＂，
Format＝＂3gp＂，
Recstorage＝30000
}}
In this example, MC indication MP distributes content identification, this sign can feed back to MC (described step s708-s709) by the incident that assigned of content identification, or can in the response message of MP, feed back (at step s706, also to carry the identification information of recorded content in the response message that MP sends, not need step s708-s709 this moment).It is 3gp that the file of recording is preserved form, and the size of recorded content is the 30000K byte.
MC can also indicate MP to detect the incident of finishing of recording.
The use-case of expanding packet rec is:
Events＝1234{rec/fail，rec/success}
MC can also detect content identification simultaneously and assign incident.
The use-case of expanding packet rec is:
Events＝1235{rec/iddetect}
In addition, recording request also can send in the ADD order, and promptly step s704 can merge among the step s702.
If step s705 MC indication MP distributes content identification, then MP distributes content identification.MP begins to record, and content is recorded in the represented file of content identification.If MC has indicated file storage type in recording request, then MP will store with the type, otherwise store with the type of MP configuration.
Step s706, MP send the response message of recording request to MC.
Step s707, MC send the response message of beginning recording request to operation controlling entity.
If step s708～s709 MC indication MP distributes content identification, then MP sends to MC, MC return response message with content identification by the NOTIFY order.At this moment, step s707, the MC loopback can be after step s708～s709 to the response message of the recording request of operation controlling entity.If MC has distributed content identification, then do not need this two steps.
The use-case that the realization content identification of expanding packet rec reports is:
Notify＝A5555{ObservedEvents＝1235{rec/iddetect(RecordingIdentifier＝“http://mediaserver/rec/example.3gp”)}}
If step s710 MC requires MP to detect the incident of finishing of recording, then when recording (comprise and completing successfully and abnormal ending) when finishing, MP reports the incident of finishing of recording by the NOTIFY order to MC.If record turkey, MP can report the reason of error code with the indication failure; If record successfully incident, MP can report and record reason and actual duration of recording and/or the actual content size of recording that completes successfully.
The use-case that reporting events is recorded successfully in the realization of expanding packet rec is:
Notify＝A5555{ObservedEvents＝1234{rec/success(size＝30000，
duration＝3600，result＝1)}}
Result is 1 in this example, and success is recorded in expression and the content recorded has reached the threshold value of the capacity of MC appointment, and the file size that record this moment is the 30000K byte, and the time of recording is 3600 seconds.
Step s711, MC send reporting events request responding message to MP.
Step s712, MC send the request of recording end to operation controlling entity.
Step s713, operation controlling entity send records the response message of end to MC.
In the embodiment of the invention two,, illustrate that the H.248 agreement of using in the embodiment of the invention after expanding realizes the method for recoding service, as shown in Figure 8, specifically may further comprise the steps to stop to be recorded as example:
Step s801, MC receive the request message that stops to record from operation controlling entity.
Step s802, MC indication MP stops to record.This can carry empty signal description by the MODIFY request command and accord with and realizing.
Step s803, MP stop recording operation.
Step s804, MP send the response message that stops to record to MC.This realizes by the MODIFY acknowledgement command.
Step s805, MC are by SUBTRACT request command indication MP deletion recording terminal.MC also can carry AUDIT descriptor requirement MP and report statistical information simultaneously.
Subtract＝A5555{Audit{Statistics}}
Send deletion recording terminal response message by the SUBSTRCT acknowledgement command to MC behind step s806, the MP deletion recording terminal.MP also can carry statistical information in this response message.As actual duration and/or the actual content size of recording recorded.
Statistics{rec/duration=3600; The duration of recorded content
Rec/size=20000; The size of recorded content }
Step s807, MC send to operation controlling entity and stop to record response message.
Need to prove, also can omit step s802 and s804 in the above-mentioned flow process, directly use step s805 and s806 deletion terminal.
In the embodiment of the invention two, be recorded as example, illustrate that the H.248 agreement of using in the embodiment of the invention after expanding realizes the method for recoding service, as shown in Figure 9, specifically may further comprise the steps with cancellation:
Step s901, MC receive the request message that cancellation that operation controlling entity issues is recorded.
Step s902, MC issue the request message that cancellation is recorded, and by Modify order H.248, carry the cancellation recording signal of expansion, current the recording of indication MP cancellation.
The use-case that the realization cancellation of expanding packet rec is recorded is:
Signals{rec/cancel}
Step s903, MP stop to record, and delete the content of having recorded.
The response message that step s904, MP transmission cancellation is recorded is to MC.
The response message that step s905, MC transmission cancellation is recorded is to operation controlling entity.
Step s906～s907: the process of finishing end points deletion between MC and the MP by the SUBTRACT order.
In the embodiment of the invention two,, illustrate that the H.248 agreement of using in the embodiment of the invention after expanding realizes the method for recoding service, as shown in figure 10, specifically may further comprise the steps to restart to be recorded as example:
Step s1001, MC receive the request message that restarts to record that operation controlling entity issues.
Step s1002, MC issue the request message that restarts to record, and by Modify order H.248, carry the recording signal that restarts of expansion, and indication MP stops current recording, and restarts to record.
The use-case that the realization of expanding packet rec restarts to record is:
Signals{rec/restart}
Step s1003, MP stop to record, and delete the content of having recorded, according to the requirement that restarts recording request, restart to record.
The response message that step s1004, MP transmission restarts to record is to MC.
The response message that step s1005, MC transmission restarts to record is to operation controlling entity.
The control that restarts to record can also realize by following method, specifically describes to be:
Step 1011:MC receives the request message that restarts to record that operation controlling entity issues.
Step 1012:MC issues the request message that restarts to record and gives MP.By the recording mode parameter that recording request signal He this signal of expansion are carried in the Modify order, indication MP restarts to record.Wherein, the value of recording mode parameter is for covering overwrite.
