Fig. 1 is the flow chart of video traffic dispatching method embodiment one of the present invention, as shown in figure 1, the method for the present embodiment can include：
S10K UE determine unit picture group（Group of Pictures, referred to as：GOP the corresponding relation of the transmission time of each picture frame and the size of the video data of each picture frame in).
In the present embodiment, UE can determine the corresponding relation of the transmission time of each picture frame and the size of the video data of each picture frame in unit GOP, video data represented by the corresponding relation belongs to the video traffic of UE progress, the corresponding relation can be set in advance in UE, it can also be a part of video data of UE real-time receptions, the corresponding relation obtained according to this partial video data, the corresponding relation can represent the corresponding relation of the size of different time and video data.Unit GOP is a GOP, therefore unit GOP includes at least two picture frames, and the transmission duration of each picture frame is identical, for example：Image frame per second be 24 each second frame number（φδ), then the transmission duration of a picture frame is about 42ms, then corresponding relation represents the size every the video data of the 42ms picture frame transmitted when sometime reaching.
For example, in dynamic image expert group（Moving Pictures Experts Group, referred to as：MPEG) in Video coding, the video sequence after coding is divided into the concept of plurality of layers, and highest level is Video Sequence Layer, next to that GOP, and-individual GOP is exactly one group of continuous picture.It is a series of picture that mpeg stream, which is finally shown, and GOP be can be with the minimum unit of absolute coding in mpeg stream, the video stream packets each encoded contain continuous GOP.Gop structure is specified comprising three kinds of picture frames in the order of picture frame, a GOP, is I frames, P frames, B frames respectively.Wherein I frames are intra-coded frames, also referred to as reference frame, and it is a complete picture and carries out absolute coding；P frames are forward predicted frames, are encoded according to previous frame information；B frames are bi-directional predicted frames, are encoded according to former frame and a later frame.At least one necessary I frame, can have variable number of B frames and P frames, can also not have B frames in GOP.GOP the first width coding picture must followed by any number of B or P picture after I picture, the picture, and any number of B frames are may be inserted between each pair I frames, P frames.Fig. 2 is image frame sequential such as Fig. 2 in a kind of unit GOP provided in an embodiment of the present invention schematic diagram, a GOP Shown, the GOP length is 10 picture frames, and frame structure is IBBPBBPBBP.
S102, UE send running time-frequency resource reservation request to base station.
In the present embodiment, UE sends running time-frequency resource reservation request it is determined that after above-mentioned corresponding relation, running time-frequency resource reservation request is generated according to corresponding relation to base station, and the running time-frequency resource reservation request includes above-mentioned corresponding relation.For example：UE to base station can send running time-frequency resource reservation request by signaling or DPCH.Base station receives the running time-frequency resource reservation request of UE transmissions, the corresponding relation that base station can be sent according to UE, it can determine that UE has periodically in unit of transfer GOP video data, therefore base station can carry out semi-static resource scheduling similarly to the prior art for the UE, namely base station determines to need configured information and the dispatching cycle of the be scheduled to UE first transmission running time-frequency resource according to running time-frequency resource reservation request, it is within dispatching cycle that unit GOP video data transmission is complete to ensure, in the transmission duration of picture frame（For example：In 42ms), if the video data of picture frame is than larger, the running time-frequency resource corresponding to 42 subframes can be so distributed for the picture frame, if the video data of picture frame is smaller, 42 subframes so can be less than for picture frame distribution, transferred with the picture frame for ensureing all in 42ms.Alternatively, base station can be according to running time-frequency resource reservation request and QoE ranks（For example set in advance for the UE）To determine the configured information and the dispatching cycle that need the be scheduled to UE first transmission running time-frequency resource, if QoE ranks are high, can be so the more transmission running time-frequency resources of UE distribution, if QoE ranks are low, then can suitably be reduced to the transmission running time-frequency resource of UE distribution.
The configured information of first transmission running time-frequency resource can indicate the positional information of the first transmission running time-frequency resource, for example：Which subframe.
S103, UE receive the reserved response of running time-frequency resource that base station is sent.
In the present embodiment, then configured information and dispatching cycle, the reserved response of generation running time-frequency resource that base station can be according to the first transmission running time-frequency resource for being scheduled to UE send the reserved response of running time-frequency resource, the running time-frequency resource, which reserves response, to be included to UE：Base station scheduling is to the first of UE configured information and the dispatching cycle for transmitting running time-frequency resource, and correspondingly, UE can receive the reserved response of running time-frequency resource of base station transmission.
Alternatively, UE can also send running time-frequency resource reservation confirmation message to base station, and to notify base station UE to have been received by the reserved response of running time-frequency resource, base station can be UE transmitting video datas according to the configured information and dispatching cycle of the first transmission running time-frequency resource.
