Optionally, the feedback, which starts message, can also carry UE marks, for indicating that the forking node feeds back the forking node to the identified UE of mark ability information of eating dishes without rice or wine.

The UE marks can be at least one of identified below：Application layer protocol user mark, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI（English：Cell Radio Network Temporary Identifier, referred to as：C-RNTI), access point identity（English：Access Point Identifier, referred to as： APID ).

(2), the base station receives the feedback instruction message that the forking node is sent, and the feedback indicates that message carries the ability information of eating dishes without rice or wine of feedback process mark, UE marks and the forking node；

Specifically, the feedback that the forking node receives the base station transmission starts message, start the feedback timer；The forking node determines the ability information of eating dishes without rice or wine of the forking node；Timer is fed back when described then, and the forking node sends feedback to the base station and indicates message.If the feedback, which starts message, carries UE marks, then the feedback indicates eat dishes without rice or wine ability information of the ability information by the forking node to the UE identified of eating dishes without rice or wine of message forking node, and the UE is designated the feedback and starts the UE marks that message is carried.If the feedback, which starts message, does not carry UE marks, then the feedback indicates eat dishes without rice or wine ability information of the ability information for all UE under the forking node to its coverage of eating dishes without rice or wine of message forking node, and the UE is designated the mark of all UE under the forking node coverage.Wherein, in order to reduce the treating capacity of the forking node, the forking node only can send packet to the base station, and the feedback that the packet includes the ability information of eating dishes without rice or wine of all UE under the forking node to the forking node coverage indicates message.

(3), the base station receives the feedback stopping message that the forking node is sent, the feedback Stop message and carry the feedback process mark.The feedback stops message, indicates that the forking node stops the ability information of eating dishes without rice or wine of the feedback forking node for the base station.Accordingly, the feedback, which stops message, can also include the mark of the UE.If the feedback stops the mark that message includes having stated UE, the feedback stopping message being used for the base station and indicates that the forking node stops the feedback forking node to the ability information of eating dishes without rice or wine for identifying identified UE.Optionally, sent in the base station to the base station before the feedback stopping message, if the feedback timer and/or the U E are identified with updating, this method also includes：The base station can also send feedback new information to the forking node, and the feedback new information carries the UE marks of the feedback process mark, the feedback timer updated and renewal；The feedback timer of the renewal, eats dishes without rice or wine cycle of ability information for indicating that the forking node adjusts the forking node to forking node described in the base station feedback.The UE marks of the renewal, for indicating that the forking node feeds back the ability information of eating dishes without rice or wine that the forking node identifies identified UE to the UE of the renewal.

604th, the data of the second data volume and the 3rd data volume are respectively allocated to the base station and the forking node by the base station according to the base station and the handling capacity and/or bit rate of the forking node.Specifically, if the ability information of eating dishes without rice or wine is handling capacity, then the base station is according to the ratio of the handling capacity of the base station and the handling capacity of the forking node, the data volume for being sent to the UE is respectively allocated to the base station and the forking node, i.e. the second data volume and the 3rd data volume.If the ability information of eating dishes without rice or wine is bit rate, then the base station is according to the bit rate of the base station and the ratio of the bit rate of the forking node, the data volume for being sent to the UE is respectively allocated to the base station and the forking node, i.e. the second data volume and the 3rd data volume.

If the ability information of eating dishes without rice or wine is handling capacity and bit rate, then the base station is according to the ratio of the handling capacity of the base station and the handling capacity of the forking node, and/or the base station bit rate and the forking node bit rate ratio, the data of the second data volume and the 3rd data volume are respectively allocated to the base station and the forking node. Wherein, second data volume and the 3rd data volume sum are difference of the data volume with first data volume for being sent to the UE.

For example, the data volume that the base station is sent to the UE is 100, and the base station is by assessing oneself transmittability within the unit interval, and the first data volume that determining the base station can transmit within the back haul link time is 10.The base station is according to the ability information of eating dishes without rice or wine of the ability information of eating dishes without rice or wine of the UE forking nodes reported, such as handling capacity, and the base station, such as the ratio of handling capacity, it is assumed that be 5:4, the 3rd data volume 50 is sent to the forking node, the UE is sent to by the forking node, remaining second data volume 40 is sent to the UE by the base station.

Further, because the channel situation of the base station and the forking node to the UE differs greatly, the channel situation can influence the data volume that the base station and the forking node are sent into the U E unit interval.Based on this, the base station is distributing the data of shunting to forking node, it is also contemplated that arrive the channel situation of the UE respectively to the base station and the forking node.Specifically,

The UE reports the base station and the forking node to arrive the CQI of the UE respectively to the base station（English：Channel Quality Indicator, referred to as： CQI ) .

For the CQI, the UE can be calculated and obtained by following index, such as：Signal to noise ratio（English：Signal-to-noise ratio, referred to as：SNR), Signal to Interference plus Noise Ratio（English：Signal to Interference plus Noise Ratio, referred to as：SINR), signal and noise distortion ratio（English：Signal To Noise And Distortion Ratio, referred to as： SNDR ) .

The base station it is determined that by send to the data distribution of the UE to the forking node when, the base station can for the UE configure and issue feedback cycle T to the UE;The UE calculates the base station in the feedback cycle T and the forking node arrives the CQI of the UE respectively, average CQI or CQI such as in feedback cycle T;Then, in the feedback cycle T, the UE sends the base station to the base station and the forking node arrives the CQI information of the UE respectively.It should be noted that the CQI information can in the lump be sent with the handling capacity and/or bitrate information of the forking node.

605th, the base station sends the data of second data volume to the UE. 606th, the base station sends the data of the 3rd data volume to the forking node.The embodiments of the invention provide a kind of method that data are sent, based on this technical scheme in this technical scheme, not only consider the back haul link time between the base station and the forking node, also by the base station and the ability of eating dishes without rice or wine of the forking node, such as handling capacity, bit rate and CQI take into account, therefore, the embodiment of the present invention causes the base station when distributing data to the forking node, base station is distributed streamed data and rationalize to the forking node.

Further, in order to improve the efficiency that the base station sends data, when the data volume for avoiding being sent to the UE when the base station is smaller, streamed data is also distributed in the base station to the UE, after base station determination sends the data of the first data volume within the back haul link time, with reference to Fig. 7, the embodiments of the invention provide a kind of method that data are sent, this method includes：

701st, base station obtains the back haul link time between the base station and forking node.

702nd, the base station determines to send the data of the first data volume within the back haul link time.

703rd, the data volume that first data volume and the base station are sent into the UE is compared.

If the 704, the base station determines that first data volume is less than the data volume that the base station is sent to the UE, the data of the second data volume and the 3rd data volume are respectively allocated to the base station and the forking node by the base station；The data of 3rd data volume are sent to the forking node by the base station；

The data of first data volume and the second data volume are sent to the UE by the base station.When first data volume is sent to the data volume of the UE less than the base station, the base station can improve the efficiency of data transfer by distributing streamed data to the forking node, now, the data of second data volume and the 3rd data volume are respectively allocated to the base station and the forking node by the base station, specific assigning process can be found in the step 604 in above-described embodiment, and the embodiment of the present invention will not be repeated here.

If the 705, the base station determines that first data volume is more than or equal to the data volume that the base station is sent to the UE, the data that the base station will be sent to the data volume of the UE are sent to the UE.When first data volume is sent to the data volume of the UE more than or equal to the base station, due to the presence of back haul link time between base station and forking node, the base station is saved by shunting, Shunting can cause the waste of resource on the contrary, the base station independent can send the data for being sent to the U E to the UE.The embodiments of the invention provide a kind of method that data are sent, made comparisons by the first data volume for sending base station to forking node in the back haul link time with the data volume that the base station is sent to the UE, avoid the data volume for being sent to the UE when base station it is smaller when, the base station still shunts the increase of waste and the forking node load of brought resource to the forking node.In order to adjust the 3rd data volume that the base station is sent to the forking node in time, in case the 3rd data volume is in the forking node congestion, the delay Shen Zhi Lost of the 3rd data volume are caused to lose, the present invention provides a kind of method that data are sent in implementing, as shown in Fig. 8, this method includes：

801st, base station obtains the back haul link time between the base station and forking node.
