Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.

Fig. 1 is the flow chart of the dispatching method embodiment one of resource of the present invention.As shown in Figure 1, the execution master of the present embodiment Body is the dispatching device of media resource, which can be realized in the form of software and/or hardware, it is preferred that the tune Degree device can integrate in the terminal with media play function, specifically, the step of the present embodiment is as follows:

S101, the resource reservation request message for being directed to media business is sent to control network element.

Wherein resource reservation request message includes the discharge model of the media business；

Terminal starts to execute media business to media server request, then need will be needed for the media business for media server Media data be sent to terminal by controlling network element, but when controlling the transmission for carrying out media data between network element and terminal, Terminal need to control network element hold consultation, so as to terminal in the resource consulted receiving media data, for terminal execute matchmaker The broadcasting of body business, wherein terminal is to control the reserved time-frequency that network element is terminal distribution to provide for the resource of receiving media data Source.And the media business discharge model for the media business that terminal is sent and the quality scale of media business, control network element can be made true Determine resource reservation schemes；Specifically, in video coding process, absolute coding is carried out by the period of GOP.In a GOP In (Group of Pictures, strategy influence coding quality), MPEG (Moving Pictures Experts Group/ Motion Pictures Experts Group, Chinese translation is dynamic image expert group) coding by picture (i.e. frame) be divided into I, P, tri- kinds of B, I are intra-coded frames, and absolute coding when coding, P is forward predicted frame, are encoded according to previous frame information, and B Two-way interpolation frame, i.e., it is maximum to be encoded wherein I frame data amount according to the information of former frame and a later frame, P secondly, B is minimum, But the data volume difference of frame type of the same race is little, such as two field pictures, if their types are all I frame, data volume base This is identical.Gop structure refers to that the distribution of GOP frame interior, such as a GOP have 10 secondary pictures, and frame sequential is respectively IBPPBPPPBP.Under normal circumstances, video playout speed is that 25 sub-pictures are per second, i.e., a sub-picture is 1/25s, is equal to 40ms. We will transmit a frame picture in 40ms.If I, P, B data amount size is respectively a, b, the c. then corresponding flow of above-mentioned GOP Model is that acbbcbbbcb. transmits a bit data amount in first 40ms, and so on；Control network element is to keep terminal complete Whole receives corresponding data volume, then needs to be reasonably terminal distribution running time-frequency resource, i.e., should be by which subframe, and is somebody's turn to do Which RB (Resource Block, resource block) in subframe distributes to terminal, then terminal receives on specified RB for working as The data volume of preceding broadcasting.

S102, the first scheduling information that control network element is sent is received.

Wherein the first scheduling information carries resource reservation schemes.

S103, according to resource reservation schemes, media flow is received on the corresponding reserved running time-frequency resource of resource reservation schemes.

Terminal can be informed in some subframe and subframe reception media number on some resource block according to resource reservation schemes According to.Since resource reservation schemes are determined according to discharge model, so terminal need to only be reserved as defined in resource reservation schemes Receiving media data on running time-frequency resource will not continue to occupy the communication resource, cause unnecessary waste, and improve the communication resource Effective rate of utilization.

Wherein, the received media data of institute and each reserved running time-frequency resource be one by one on each reserved running time-frequency resource It is corresponding.

In the present embodiment, by sending the media discharge model of media business to control network element, so that control network element determines Reasonable resource reservation schemes, so that terminal only carries out media number on each reserved running time-frequency resource as defined in resource reservation schemes According to reception operation, compared with the scheme of progressive download in the prior art, terminal will not occupy always resource in the present embodiment, The possibility for largely wasting received media data is also avoided, to save the communication resource.

Fig. 2 is the flow chart of the dispatching method embodiment two of resource of the present invention.As shown in Fig. 2, the present embodiment is in Fig. 1 institute On the basis of the embodiment shown, further description is made, specific as follows:

S201, the test media data of acquisition is tested, determines media coding model.

Terminal can obtain one section of GOP as test media data to media server, analyze its frame sequential, which is For above-mentioned media coding model.

Preferably, when terminal receives the data volume of m size, required resource will receive the shadow of the quality scale of media business It rings, therefore, terminal can also test communication network, determine the quality scale of media business.

S202, the resource reservation request message for being directed to media business is sent to control network element.

The resource reservation request message includes the discharge model of the media business.

Preferably, resource reservation request message may also include the quality scale of the media business；

S203, the first scheduling information that the control network element is sent is received.

First scheduling information carries resource reservation schemes.

S204, according to the resource reservation schemes, on each reserved running time-frequency resource as defined in the resource reservation schemes Carry out the reception operation of media data.

Wherein S202~S204 can refer to aforementioned S101~S103.

Wherein, the reserved running time-frequency resource is each to reserve each resource as defined in the resource reservation schemes in subframe Block；The reserved subframe is subframe as defined in resource reservation schemes described in the reservation period of each preset duration.Fig. 3 is this hair The schematic diagram of subframe is reserved in bright embodiment two.As shown in figure 3, then being changed over time, often with preset duration for T ms (millisecond) T ms is a reservation period, in Fig. 3 by taking two reservation periods as an example, a when a length of GOP for said one reservation period Duration, then in each reservation period, the rectangle of dash area and the rectangle of non-shaded portion represent a subframe, and The rectangle of dash area is then each reserved subframe as defined in resource reservation schemes, and by taking Fig. 3 as an example, resource reservation schemes are defined Within each period, the 1st, the 2nd, the 6th, the 9th and the 11st subframe is reserved subframe；Terminal is in each reserved subframe The upper reception operation using resource block as defined in reserved resource scheme；Wherein, received media number on running time-frequency resource is each reserved It is controlled according to the size of amount by control network element.

S205, judge whether to listen to the relevant information of dynamic dispatching；If so, executing S206；If it is not, continuing to execute S204。

While executing S204, terminal also needs to be monitored in each subframe；Specifically, executing media in terminal Business and in the reception operation for carrying out media data on reserved running time-frequency resource, it is possible that not needing continuous reservation resource Event, or need received data volume more, for example, control network element needs terminal in unreserved subframe in a cycle T Upper receiving media data, then terminal listens to the relevant information (DCI) of dynamic dispatching in the unreserved subframe, i.e., does not have originally Being reserved can be used to carry out reception operation by dynamic dispatching as the subframe of reserved subframe；It is contemplated that, it is above-mentioned reserved Subframe is reserved specified in scheme can also be cancelled by the relevant information of the dynamic dispatching listened to.

If S206, the relevant information for listening to dynamic dispatching on current subframe, according to the correlation of the dynamic dispatching The corresponding scheme of information carries out reception operation.

It should be understood that terminal when executing media business, is to continue to keep listening state, i.e., dynamic is listened to each time The relevant information of scheduling then carries out reception operation according to the corresponding scheme of relevant information of the dynamic dispatching.

For example, if the relevant information for the dynamic dispatching that current subframe is monitored is that reserved subframe cancels information, according to The corresponding scheme of the relevant information of the dynamic dispatching carries out reception scheduling, comprising: the reserved running time-frequency resource after current subframe On operated without the transmission of media data, avoid continuing to occupy wireless resource block, the communication resource caused to waste, such as current son Frame is the 3rd subframe of a reservation period, and according to the regulation of resource reservation schemes, terminal needs in this reservation period In each reserved subframe in 6th subframe, the 9th subframe ... and subsequent each reservation period, using resource reservation Resource block as defined in scheme carries out the reception of media data, but cancels message due to listening to reserved subframe on current subframe, then Terminal does not have to the reception operation for carrying out media data in each reserved subframe later；Wherein received subframe cancels information Adoptable format can be as shown in table 1:

Table 1:

Such as above-mentioned table 1, subframe, which cancels information, can 5 kinds of formats, and each format has been correspondingly arranged not in each field Same information, such as in 0 format of DCI format, be set in field " TPC command for scheduled PUSCH " ' 00 ', and in DCI format1 format, field " TPC command for scheduled PUSCH " is sky, is indicated with N/A； Above-mentioned subframe is cancelled the adoptable format of information and is only used for for example, can according to need flexible setting in practical applications The format of frame cancellation information.

Further, after media business being suspended due to user's using terminal, user again using terminal to media sector Business carries out recovery broadcasting, then terminal needs continue to obtain media data, if then terminal is listening to the reserved subframe cancellation letter Reserved subframe reconstruction information is listened in the second subframe after the current subframe of breath, then using second subframe as weight The starting subframe in period is built, and according to the resource reservation schemes, the resource reservation schemes regulation within each reconstruction period Reserved subframe on carry out media data reception operation, wherein rebuild the period duration and aforementioned reservation period when appearance Deng.Fig. 4 is the schematic diagram for the reserved subframe rebuild in the period in the embodiment of the present invention two.As shown in figure 4, moment t1 listen to it is pre- Subframe is stayed to cancel information, i.e. t1 is that the above-mentioned current subframe for listening to reserved subframe cancellation information listens to after m seconds Reserved subframe rebuilds message, is at this time (t1+m) second at moment, as above-mentioned second subframe, and terminal listens in the second subframe Subframe reconstruction information, then by second subframe, every T ms sections were pressed then within the reconstruction period as a reconstruction period According to the resource reservation schemes, is reserved as defined in the resource reservation schemes within each reconstruction period and carry out media number in subframe According to reception operation；Such as example in Fig. 3, resource reservation schemes were provided in each period, the 1st, the 2nd, the 6th, the 9th and 11st subframe is reserved subframe, then within each reconstruction period, still according in each period as defined in resource reservation schemes 1st, the 2nd, the 6th, the 9th and the 11st subframe is reserved subframe；Wherein reserve the adoptable lattice of subframe reconstruction information Formula such as table 2:

Table 2

Such as above-mentioned table 2, reserved subframe reconstruction information can have in 5 kinds of formats, such as 0 format of DCI format, then be Field " Cyclic shift DMRS " is set to ' 111 ', and in DCI format1 format, field " Cyclic shift DMRS " For sky, indicated with N/A；The above-mentioned reserved adoptable format of subframe reconstruction information is only used for for example, in practical applications may be used The format of subframe reconstruction information is reserved with flexible setting as needed.

If not hearing the relevant information of dynamic dispatching on the current subframe, illustrate that terminal can be still according to the money Source reservation schemes carry out the reception operation of media data on each reserved running time-frequency resource as defined in the resource reservation schemes, Continue to execute S204.

It should be added that above-mentioned need to may be to be triggered by terminal to the event that resource is scheduled, i.e., eventually While executing S204, terminal sends the trigger condition of dynamic dispatching to the control network element at end.

Optionally, when user's using terminal terminates media business, such as closing broadcasting, then terminal is also needed to control network element hair Reserved running time-frequency resource release message is sent, so that after control network element discharges at the time of receiving reserved running time-frequency resource release message Reserved running time-frequency resource；The format such as table 3 that the reserved running time-frequency resource release message can be taken:

Table 3

The format that running time-frequency resource release message is reserved shown in above-mentioned table 3 is only used for for example, in practical applications It can according to need flexible setting format.

In the present embodiment, the dispatching method of resource is combined using resource reservation and dynamic dispatching, i.e., pre- by resource Stay scheme that can efficiently use the communication resource, it, can be reasonable to use communication in real time according to dynamic dispatching in combination with dynamic dispatching Resource, to save the unnecessary wasting of resources while guaranteeing the quality scale of media business.
