Description
Technical field
The present invention relates to the media transport technology of applied business, particularly a kind of media data caching method and system of applied business.
Background technology
At present, in some applied business, introduced a kind of media buffer mechanism, briefly be exactly: the medium transmit leg can at first be sent to media data the enterprising row cache of service customer end or service server when preparing media data but also not receiving medium recipient's affirmation reception indication; When service customer end or service server receive described affirmation when receiving indication, the media data with institute's buffer memory is sent to the medium recipient again.After adopting this kind media buffer mechanism, obtaining to be mail to the medium recipient rapidly after described affirmation receives indication from the media data of medium transmit leg, thereby improving media delivery speed.The typical services of using this kind media buffer mechanism is exactly PTT in the cellular system (PoC) business, and this paper only is example with the PoC service, and problem and solution of the present invention that prior art is occurred are elaborated.Medium transmit leg/recipient as herein described is often referred to and participates in professional transmit leg user and transmit leg application server, and recipient user and recipient's application server, also may refer to be used to receive/send the equipment of media data in some cases, such as: be connected answer phone on the service customer end, video tape recorder or the like.
In PoC1.0, introduced the media cache function of PoC server, the medium transmit leg carries out buffer memory receiving that right to speak authorizes notice back and just media data is sent to the PoC server by the PoC server.When the PoC server receive receive indication from medium recipient's affirmation after, the media data that just sends self buffer memory at once is to these medium recipient, answer the medium transmit leg user required time delay of making a speech thereby shortened the medium recipient greatly, to promote user's PoC service impression.Because the PoC client is more understood applied business to information such as the requirement of medium and features, so the PoC2.0 regulation can be brought in buffered media data by PoC server or PoC client.Consider the finite capacity of PoC client, the PoC client is at first carried out buffer memory to the media data that receives, by the situation of PoC server real-time monitoring PoC client media buffer.When the buffer memory of PoC discovering server PoC client when overflowing, notice PoC client is sent to the PoC server with media data, and the PoC client is again with the media data of buffer memory and the follow-up media data of sending are sent to the PoC server in this service conversation.
When PoC server or PoC client have been carried out buffer memory to the media data of medium transmit leg, the affirmation of but slowly not receiving the medium recipient receives when indicating, about the problem of these media datas of how handling institute's buffer memory, existing PoC service standard is clearly definition also.If continue these media datas of buffer memory, then the media data of institute's buffer memory will take storage resources for a long time, making affirmation receive indication can't send in case communication link fails has taken place, then will accumulate the media data that is ready for sending in a large number rapidly on PoC client or the PoC server, this will have a strong impact on PoC client or the normal Business Processing of PoC server.
In addition, if the time of media data buffer memory is longer, they often have little significance for the user.Such as: transmit leg user some speech datas of having made a speech the back buffer memory for the first time, but passed through the long period and received that just recipient user's affirmation receives indication, the transmit leg user need pass to recipient's user's voice variation took place this moment, the transmit leg user needs speech again to transmit new speech data to recipient user, and promptly the speech data of original buffer memory lost efficacy.If send to recipient user with original data in buffer this moment, then be undoubtedly a kind of transmission of invalid data, thus waste system transmissions resource.But for the problem of media data how to handle these inefficacies, existing PoC service standard does not relate to yet yet.
As seen, the media buffer mechanism of existing applied business is perfect not enough, cause to receive at communication failure etc. and confirm to receive indication or the long period just can obtain confirming to receive under the situation of indication, have a strong impact on quality of service probably, and the problem that the media data that can't solve buffer memory lost efficacy, thereby cause system resource to waste in a large number.

The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The invention discloses a kind of media data caching method of applied business, when service customer end or service server received media data from the medium transmit leg, it was mainly handled thought and is: for the media data that receives is provided with the buffer memory timeliness row cache of going forward side by side; In this buffer memory timeliness, when receiving when receiving indication from medium recipient's affirmation, this service customer end or service server send the media data of self buffer memory to these medium recipient.By this kind treatment mechanism, the media data of each buffer memory has buffer memory timeliness separately, thereby can guarantee the efficient media data passes to the medium recipient.
And when exceeding the buffer memory timeliness, when promptly the media data of institute's buffer memory lost efficacy, the inventive method provided two kinds of processing methods substantially: one, the media data of service customer end or service server deletion self institute's buffer memory; Two, service customer end or service server return to the medium transmit leg and exceed the indication of buffer memory timeliness; Reception is from the indication of the buffer memory of this medium transmit leg, determines the media data of deletion institute buffer memory or continues this media data of buffer memory and reset the buffer memory timeliness or upgrade this media data and reset the buffer memory timeliness according to this buffer memory indication.
The inventive method can be implemented in service customer end, also can be implemented in service server.In PoC service, service customer end is the PoC client, and service server is the PoC server.Be implemented in the PoC client respectively with the inventive method below and the PoC server is an example, the handling principle of this method is described in detail.
Fig. 1 is the inventive method one preferred embodiment handling process schematic diagram.In the present embodiment, be responsible for buffered media data, and media data is implemented timeliness control by the PoC client.As shown in Figure 1, the concrete processing comprises:
Step 100: the medium transmit leg receives from the right to speak of PoC server by the PoC client and authorizes notice, and the media data of uploading self then is to the PoC client.
Step 101:PoC client-cache is from the media data of medium transmit leg, and the buffer memory timeliness of this media data is set.When in this buffer memory timeliness, receiving affirmation that the medium recipient sends by the PoC server when receiving indication, execution in step 102.When the time of this media data buffer memory exceeds this buffer memory timeliness, execution in step 103 or step 104.
In view of above-mentioned when exceeding the buffer memory timeliness two kinds of processing methods provided by the invention, in this step, when the time of media data buffer memory exceeds this buffer memory timeliness, also can adopt two kinds of processing methods, so but this moment execution in step 103 or step 104.What adopt when execution in step 103 is first kind of processing method noted earlier, and what adopt when execution in step 104 is second kind of processing method noted earlier.
Step 102: this PoC client is uploaded to the PoC server with the media data of step 101 buffer memory, thereby this media data is sent to the medium transmit leg, finishes current handling process.
Step 103: the media data of deletion step 101 buffer memory, and remove set buffer memory timeliness, finish current handling process.
Step 104:PoC client sends to described medium transmit leg and exceeds the indication of buffer memory timeliness, prompting medium transmit leg is handled the media data that exceeds the buffer memory timeliness, the return cache indication again of medium transmit leg, this buffer memory indication shows the processing method to these media datas, as: deletion or continuation buffer memory or renewal or the like.
Here, the so-called media data that upgrades has two kinds of situations: one, receive the new media data that new media data replaces with the media data of original buffer memory current reception from the medium transmit leg; Two, receive new media data from the medium transmit leg, on the basis of the media data of original buffer memory, increase the new media data of current reception.
Step 105:PoC client is determined deletion or is continued buffer memory or the media data of renewal current cache by the buffer memory indication that receives.When the deletion media data, its buffer memory timeliness to be removed simultaneously, when continuing buffer memory or upgrading media data, also the buffer memory timeliness will be reset.
Fig. 2 is the inventive method one preferred embodiment handling process schematic diagram.In the present embodiment, be responsible for buffered media data, and media data is implemented timeliness control by the PoC server.As shown in Figure 2, the concrete processing comprises:
Step 200: the medium transmit leg receives from the right to speak of PoC server by the PoC client and authorizes notice, passes through the media data of PoC client upload self then to the PoC server.
The PoC client upload media data that passes through described here comprises some kinds of situations for the PoC server:
One, when by PoC server buffer media data, the PoC client directly passes to media data the PoC server.
Two, when by PoC client-cache media data, the PoC client is at first carried out buffer memory to the media data that receives, by the situation of PoC server real-time monitoring PoC client media buffer.When the buffer memory of PoC discovering server PoC client when overflowing, notice PoC client is sent to the PoC server with media data, and the PoC client is again with the media data of buffer memory and the follow-up media data of sending are sent to the PoC server in this service conversation.
Three, the PoC client media data that receives of buffer memory at first need not to wait for the notice of PoC server, and regularly the media data of self buffer memory is sent to the PoC server.
Step 201:PoC server buffer is from the media data of PoC client, and the buffer memory timeliness of this media data is set.When in this buffer memory timeliness, receiving affirmation that the medium recipient sends when receiving indication, execution in step 202.When the time of this media data buffer memory exceeds this buffer memory timeliness, execution in step 203 or step 204.
Wherein, PoC server method that the buffer memory timeliness is set has three kinds substantially:
One, the buffer memory timeliness of current media data is set according to the pre-configured strategy of PoC server self, this strategy can for: the buffer memory timeliness is set or the buffer memory timeliness is set or buffer memory timeliness or the like is set by the computational methods calculating buffer memory timeliness of media data size and appointment or by media data type by quality requirement (QOE, the Quality ofExperience) parameter of experiencing of current media data by quality of service requirement (QoS) parameter of current media data.The present invention is provided with the buffer memory timeliness to which kind of strategy of concrete configuration and does not limit.
Two, the buffer memory timeliness of sending by the PoC client is provided with.Because the PoC client is more understood requirement and the feature of current application business to media data, be more convenient for determining the buffer memory timeliness of media data, therefore, as shown in Figure 2, the PoC client also can be determined the buffer memory timeliness of this media data and send this buffer memory timeliness to the PoC server that the PoC server will be provided as the buffer memory timeliness that receives the buffer memory timeliness of the media data of current cache when transmission of media data is given the PoC server.
Three, use the buffer memory timeliness of medium transmit leg indication.Wherein, the medium transmit leg can send the buffer memory timeliness of this media data simultaneously to the PoC server when the upload media data; The PoC server also can send information to the medium transmit leg when receiving media data, prompting medium transmit leg is provided with the buffer memory timeliness and sends to the PoC server.
In addition, the PoC client determines that the method for buffer memory timeliness has three kinds substantially:
One, the buffer memory timeliness of current media data is set according to the pre-configured strategy of PoC client self.
Two, use the buffer memory timeliness of medium transmit leg indication.Wherein, the medium transmit leg can send the buffer memory timeliness of this media data simultaneously to the PoC client when the upload media data; The PoC client also can send information to the medium transmit leg when receiving media data, prompting medium transmit leg is provided with the buffer memory timeliness and sends to the PoC client.
Three, use the buffer memory timeliness of PoC server indication.Wherein, the PoC server can be monitored the situation of PoC client receiving media data in real time, can be that the media data of the current reception of PoC client is provided with the buffer memory timeliness and sends to this PoC client by self pre-configured strategy.
Step 202: this PoC server is sent to the medium transmit leg with the media data of step 201 buffer memory, finishes current handling process.
Step 203: the media data of deletion step 201 buffer memory, and remove set buffer memory timeliness, finish current handling process.
Step 204:PoC server sends to described medium transmit leg by the PoC client and exceeds the indication of buffer memory timeliness, prompting medium transmit leg is handled the media data that exceeds the buffer memory timeliness, the medium transmit leg is again by the indication of PoC client return cache, this buffer memory indication shows the processing method to these media datas, as: deletion or continuation buffer memory or renewal or the like.
Step 205:PoC server is determined deletion or is continued buffer memory or the media data of renewal current cache by the buffer memory indication that receives.When the deletion media data, its buffer memory timeliness to be removed simultaneously, when continuing buffer memory or upgrading media data, also the buffer memory timeliness will be reset.
In the above-described embodiments, the media data that the medium transmit leg transmits may be a kind of data of medium type, it is multi-medium data that this media data also may be made up of the data of multiple medium type, such as: the multi-medium data that constitutes by voice data and video data.And at different medium types, the buffer memory timeliness will be different, and buffer memory timeliness voice data is short or the like such as: the buffer memory timeliness of video data is long.So in the above-mentioned handling process, when the media data of institute's buffer memory is a kind of data of medium type, then set buffer memory timeliness is a buffer memory timeliness; When the media data of institute's buffer memory is the data of multiple medium type, then set buffer memory timeliness can or be the tabulation of a plurality of buffer memory timeliness of multiple medium type correspondence for a buffer memory timeliness.Wherein, according to the incidence relation of various medium types in same session, corresponding, also have certain correlation between the buffer memory timeliness of various medium types.The present invention does not limit for the concrete form of buffer memory timeliness, all belongs to buffer memory timeliness category of the present invention as long as can be used to limit the information of the media data buffer memory duration of one or more medium types.
Based on said method, the present invention also provides a kind of media buffer system of applied business, this system can be arranged in service customer end or the service server, it comprises: be used for the media buffer unit of buffered media data on existing business client or the service server, also further comprise: caching control unit.Fig. 3 forms structural representation for system of the present invention one preferred embodiment.As shown in Figure 3, system of the present invention comprises: media buffer unit and caching control unit.
Wherein, the media buffer unit, be used to receive buffer memory control command from caching control unit, from the medium transmit leg receiving media data row cache of going forward side by side, determine to delete the media data of buffer memory or output medium data and give the medium recipient or receive new media data and upgrade the media data of buffer memory according to receiving the buffer memory control command.Caching control unit is used to be provided with the buffer memory timeliness of media data, and the affirmation that receives from the medium recipient receives indication, sends a buffer memory control command media buffer unit.
When the media buffer unit receives media data, caching control unit will be provided with the buffer memory timeliness for this media data, and begin the cache-time of this media data is carried out timing.When caching control unit in the buffer memory timeliness received the confirmation the reception indication, the buffer memory control command that sends the indication transmission medium was to the media buffer unit, thereby the media data of media buffer unit output self buffer memory is to the medium recipient.When exceeding the buffer memory timeliness, caching control unit will send the buffer memory control command of indication deletion to the media buffer unit, and the media data of self buffer memory will be deleted in this media buffer unit.Here, caching control unit can be provided with the buffer memory timeliness by the strategy that is disposed at self, also can be provided with from the service customer end or the medium transmit leg reception buffer memory timeliness of outside.
In addition, when exceeding the buffer memory timeliness, caching control unit also can adopt another kind of processing mode: caching control unit output exceeds the buffer memory timeliness indicates to the medium transmit leg, receives the buffer memory indication from the medium transmit leg, gives the media buffer unit by this buffer memory indication output buffers control command.This buffer memory indication and buffer memory control command can be represented deletion or continue buffer memory or upgrade media data.When this buffer memory indication expression continued buffer memory or upgrades media data, caching control unit also will be reset the buffer memory timeliness of media data, and it can be provided with by self configured strategy, also can be provided with by the buffer memory timeliness that the buffer memory indication is carried.
When the invention described above method and system is applied to PoC service; service customer end and service server are respectively PoC client and PoC server; and when being applied to other applied business; the concrete entity of service customer end and service server representative will change; such as: Conference client and Conference server in meeting (Conference) business; but handling principle of the present invention does not change; therefore this paper describes in detail no longer one by one, and all in protection scope of the present invention.
