Step 701, PVR-SCF triggers recorded event according to the recording task of customization or the real-time recording request of receiving of recording task, sends to PVR-MF and records message, and request PVR-MF begins to record.

Wherein, recording message can be the Invite message of SIP, portability user's identify label in this message.

Step 702, PVR-MF is to PVR-SCF return authorization response message.

Wherein, authorization response message can be the 200OK message of SIP.And in this step, PVR-MF can obtain the delegatable current memory space size (total storage capacity size that is had when the user is signatory in the present embodiment and the big I of delegatable current memory space that the user had are stored on the MF) that the user has according to user's identify label, and PVR-MF can calculate desiring the required memory space that takies of recorded content, afterwards can be according to delegatable current memory space size and the required memory space size of this recorded content that the user had, judge whether to satisfy recording request, if current memory space more than or equal to the required memory space of recorded content, is then recorded media content; Otherwise can directly stop recording task and can initiate notice to PVR-SCF.Perhaps, also can carry out part to the media content that requires to record and record, but determining section satisfied recording request this moment according to user's configuration.

Wherein, memory space can be a time quantum, also can be amount of space.Being that the delegatable current memory space size that the user has can be the storage duration, also can be storage size.Equally, PVR-SCF sends to the time related information that portability is recorded in the message of recording of PVR-MF in step 701, as time started and the duration of recording, or time started and concluding time, or the information of desiring to record such as channel program, then PVR-MF can judge the required total duration that takies of this recorded content according to above-mentioned time related information.Record further in the message also the portability coded message or and media quality information etc., then PVR-MF can according to the coded message of required total duration that takies of recorded content and recorded content or and the media quality information calculations go out the required occupation space size of recorded content.

In the present embodiment, if in the time of can't knowing the required memory space of recorded content, for example, in step 701 PVR-SCF send to recording of PVR-MF only carry in the message record begin the request, then this moment, PVR-MF can not judge whether to satisfy recording request, perhaps also can think since 0 to record, then, just can be judged as and satisfy recording request as long as the user also has memory space.

Step 703, the recording and storing amount of PVR-MF tolerance recorded content.

Wherein, the recording and storing amount can be the duration of recording of record, also can be the space of recording that records.Wherein, record the space and can be according to record record duration and coded message or and the memory space of media quality information calculations, also can be the shared memory space of measuring of recorded content reality.

Step 704, when the recording and storing amount reaches the required memory space of recorded content (being this recording task required storage), or the recording and storing amount reach that the user has current memory space the time, PVR-MF can send to PVR-SCF and stop recording request message, and stop recording or suspending and record, or delete recorded content etc.Further, can report PVR-SCF with recording the result.

Wherein, stop the Bye message that recording request message can be SIP.

Step 705, PVR-SCF returns to PVR-MF and stops response.Further, the result that records that PVR-SCF can report PVR-MF offers recording request person, i.e. recording task registered entities or recording request sending entity.

Wherein, stopping to respond can be the 200OK message of SIP.

In addition, in the present embodiment if PVR-SCF receive the user stop recording request in real time, then PVR-SCF can send to PVR-MF and stop authorization messages, PVR-MF returns to PVR-SCF and stops response message.

Also can in recording message, carry the delegatable current memory space that the user has in the step 701 in the foregoing description, then PVR-MF obtains the delegatable current memory space size that the user has in the step 702 from record message, and whether satisfies the judgement of recording request in view of the above.

In the present embodiment, PVR-SCF comprises and records authorization module; PVR-MF comprises and records module, storage metric function module and record control function module.

Step 801, PVR-SCF triggers recorded event according to the recording task of customization or the real-time recording request of receiving of recording task, sends to PVR-MF and records message, and request PVR-MF begins to record.

Wherein, recording message can be the Invite message of SIP, the delegatable current memory space that the portability user is had in this message, the i.e. maximum storage that can record, this maximum storage can be time quantum, also can be amount of space, can also be for recording number of times or recording object number etc.

Step 802, PVR-MF is to PVR-SCF return authorization response message.

Wherein, authorization response message can be the 200OK message of SIP.

In this step, PVR-MF can judge whether to satisfy recording request according to recording the delegatable current memory space size that the user had of carrying in the message, and the description in detailed process and the step 702 shown in Figure 7 is similar.If current memory space more than or equal to the required memory space of recorded content, is then recorded media content; Otherwise can directly stop recording task and can initiate notice to PVR-SCF.Perhaps, also can according to user's configuration to the media content that requires to record carry out part and record.

Perhaps, if can't know the required memory space of recorded content the time, then this moment, PVR-MF can not judge whether to satisfy recording request, perhaps also can think since 0 to record, and then as long as the user also has memory space, just can be judged as and satisfy recording request.

Step 803, the recording and storing amount of PVR-MF tolerance recorded content.

Step 804, when the recording and storing amount reaches the required memory space of recorded content, or the recording and storing amount reach that the user has current memory space the time, PVR-MF correspondingly recording process information (record and finish or the memory space deficiency) reports PVR-SCF.

Wherein, report and to realize by the message such as Publish/Info/Message/Notify of SIP.

Step 805, PVR-SCF carries out control and treatment according to the recording process information that is received to this recording task, can send to PVR-MF to stop authorization messages, this stops authorization messages and can be used for notifying PVR-MF to stop recording or suspending and record, or deletes recorded content etc.

Wherein, stop authorization messages and can be Bye message.

Step 806, PVR-MF returns to PVR-SCF and stops response.
