Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Embodiment 1
The embodiment of the invention 1 provides a kind of method that reports buffer state, comprising: UE sends buffer state and characteristic information, and wherein, characteristic information is used to indicate this buffer state corresponding to the VOIP business.
Further, characteristic information can be the dedicated logical channel group id LCG ID of this buffer state of indication corresponding to the VOIP business, perhaps Logic Channel Identifier LC ID.
In the present embodiment, when UE reports buffer state, provide this buffer state pairing service feature information, thereby making network node such as eNB identify the pairing business of buffer state according to characteristic information is the VOIP business, and can further carry out scheduling of resource at the VOIP business, save the uplink scheduling signaling, avoid the wasting of resources.
Embodiment 2
Referring to Fig. 1, the embodiment of the invention provides a kind of method that reports buffer state, can comprise the steps:
101:eNB receives the service request of UE or core net transmission, determines that according to the QCI in this request (Quality ControlIndication, quality control is indicated) business of this UE request transmission is the VOIP business;
102:eNB is the special-purpose LCG of the VOIP business configuration of this UE, and sends DRB (Data RadioBearer, the Data Radio Bearer) configuration information of VOIP business, and this configuration information comprises the sign ID of this special use LCG;
ENB is by sending this LCG ID notice UE in this step: this LCG is used to send the buffer state of VOIP business; Accordingly, after UE receives this LCG ID, with it as the indication of buffer state corresponding to the VOIP business.This step can suppose that this LCG ID is 3.
103:UE sends buffer state and is used to indicate the LCG ID of this buffer state corresponding to the VOIP business;
Concrete, existing BSR trigger condition all is applicable to present embodiment, and UE can be carried at this buffer state and LCG ID (being 3) among the BSR.Further, UE can adopt short BSR or long BSR according to actual conditions, and does not influence the realization of present embodiment.
104:eNB receives this LCG ID, knows the buffer state that comprises the VOIP business among the BSR that comprises this LCG ID.
In the present embodiment, eNB can be this VOIP service dispatching semi-static scheduling resources according to buffer state further, and notifies this UE.
In the present embodiment, UE sends to eNB in the lump with the LCG ID of the indication VOIP business of eNB configuration and the buffer state of this VOIP business, make eNB can know the buffer state of reception is corresponding to which kind of business, the VOIP business can be treated with a certain discrimination with other business, for example eNB can no longer be this VOIP traffic assignments dynamic dispatching resource, thereby avoids not causing the wasting of resources owing to the resource of distributing is used; And for example, eNB can need not to change the semi-static resource of having distributed for UE for this VOIP traffic assignments dynamic dispatching resource when the VOIP traffic carrying capacity that happens suddenly bigger, thereby the resource of avoiding repeatedly changing to the UE configuration causes a large amount of Signalling exchanges.
The replacement scheme of present embodiment 2 is: adopt the LC ID of agreement regulation to indicate the buffer state of UE transmission corresponding to the VOIP business, be LC ID rather than the LCG ID that UE will indicate the VOIP business, buffer state with the VOIP business sends to eNB, accordingly, eNB discerns the buffer state that receives according to this LC ID.Certainly, eNB also can be when being the VOIP traffic assignments LC of this UE, and the LC ID of this indication VOIP business is sent to UE.
Embodiment 3
The embodiment of the invention 3 provides a kind of method that reports buffer state, comprising: when the data length of the VOIP business that arrives buffering area reaches the length of semi-static scheduling resources, send buffer state.
Further, UE can calculate the difference of the length of the data length of VOIP business of reception and this semi-static scheduling resources, if this difference greater than default thresholding, then UE sends buffer state, wherein, default thresholding can be more than or equal to 0.
Present embodiment, in time obtains enough transfer resources, thereby guarantees in time to send data when the bigger VOIP business datum amount of burst by UE, avoids losing of VOIP business datum, improves the VOIP quality of service.
Embodiment 4
The embodiment of the invention 1,2 and replacement scheme thereof can combine with embodiment 3,4 are elaborated by the following examples.Referring to Fig. 2, embodiment 4 provides a kind of method that reports buffer state, can comprise the steps:

The method that UE can adopt embodiment 1,2 and replacement scheme thereof to provide in this step is carried out the transmission of BSR.
202:eNB distributes the SPS resource for this UE;
The follow-up data (being called for short second packet) that 203:UE detects this VOIP business arrives, and calculates the difference of this second length of data package and the SPS resource size that has distributed; If this difference then carries out 204 less than default thresholding; Otherwise, carry out 205.
204:UE sends second packet of VOIP business;
Concrete, UE can use the SPS resource of having distributed to send this second packet, also can use dynamic resource to send this second packet.
In this step, because above-mentioned difference is less than default thresholding, UE can not send current buffer state at this VOIP business to eNB.
205:UE sends BSR, and this BSR comprises the current buffer state of VOIP business, and second length of data package;
In this step, UE sends BSR and can specifically comprise: UE triggers BSR, obtains the resource that eNB distributes, and utilizes the resource that obtains to send BSR.Wherein, the resource that UE obtains may be the SPS resource, also may be dynamic resource.
206:eNB carries out scheduling of resource according to this BSR to this VOIP business.
Further, arrive if UE detects the follow-up data of this VOIP business, the 3rd, the 4th for example follow-up packet etc. promptly satisfy the condition of UE calculated difference in the step 403, and then UE can repeat the step of present embodiment step 403 to 405.
In the present embodiment, when the VOIP business datum length that arrives does not change, or when surpassing default threshold value, UE can continue to use the SPS resource of original activation to send data, when this VOIP business datum length that arrives surpasses threshold value, report BSR to eNB, thereby save signaling consumption; Perhaps, UE can be in the VOIP business datum length continuous several times that arrives during greater than the length of the SPS resource of original activation, send BSR to eNB, for example, the VOIP business datum length that arrives when UE accumulative total is continuously greater than the number of times of the length of the SPS resource of original activation, when this number of times during, send BSR to eNB greater than the preset times thresholding.In addition, bigger if the eNB continuous several times detects the VOIP data length that UE sends, perhaps UE continuous several times detect VOIP business datum length big and report BSR after, eNB can be adjusted into the semi-static scheduling resources that UE distributes.
