Method and apparatus provided by the embodiment of the present application are done further below in conjunction with attached drawing and specific application scenarios Detailed description:

Embodiment one

A kind of method for transmitting uplink data provided by the embodiment of the present application is done further below in conjunction with Figure of description 2 Detailed description, this method specific implementation are that (Buffer Status Report buffers shape in mobile access equipment application BSR State report) before, i.e. before how many data will be sent in mobile access equipment signals base uplink buffer, this method is specifically real Now it may comprise steps of:

Step 201, before mobile access equipment sends upstream data to base station, RSRP measurement is carried out, measurement result is obtained;

In the embodiment of the present application, which may include RSRP and SINR (Signal to Interference Plus Noise Ratio, Signal to Interference plus Noise Ratio), wherein carrying out RSRP measurement, obtain the specific implementation of measurement result Mode may is that

Mobile access equipment periodically carries out RSRP measurement according to preset interval, and measurement at least twice is obtained As a result the measurement result is obtained after carrying out arithmetic average.Such as: the every 10ms of access device carries out RSRP, SINR measurement once, It is error in order to reduce measurement bring, arithmetic average can be carried out using preceding 10ms data calculate new RSRP numerical value. The specific calculation formula for calculating RSRP numerical value may is that RSRP=RSRP0+RSRP1+RSRP2+……+RSRP10

Step 202, obtained from the broadcast message that base station issues preset MCL (Minimum Coupling Loss, most Small coupling loss) rank and RSRP corresponding relationship;

Base station can save the corresponding relationship between MCL rank and RSRP in advance, in order to guarantee that mobile access equipment can be true Fixed one meets the MCL rank of own net situation, and base station then can will be corresponding between MCL rank and RSRP by broadcast message Relationship is sent to mobile access equipment, and mobile access equipment is enabled to determine that current network conditions are corresponding according to the corresponding relationship MCL rank.

Step 203, it is determined first corresponding to the measurement result according to the corresponding relationship of the MCL rank and RSRP MCL rank;

It currently measures obtained RSRP (i.e. measurement result) and embodies the current corresponding network condition of mobile access equipment, Mobile access equipment is based on current measurement and obtains corresponding MCL rank from MCL rank and RSRP corresponding relationship, then can be with More accurately determine current network conditions should corresponding covering grade, and then effectively guarantee random access send above line number According to the success rate of message and the success rate of response platform query messages.

Step 204, it is matched after corresponding random access parameter accesses the base station according to the first MCL rank and sends institute State upstream data.

After the MCL rank corresponding to the current RSRP of determination, then msg1/msg2 random access can be carried out;Then into Row uplink BSR application can improve mobile access equipment by this way and be successfully accessed rate, and improve data transfer success Rate.

In this embodiment, the determination of MCL rank is all carried out before mobile access equipment sends upstream data every time, then The transmission of upstream data is carried out according to determining MCL rank, specific implementation may is that

If identified 2nd MCL rank is identical when the first MCL rank is with preceding one-shot measurement RSRP, institute is used It states covering grade corresponding to the 2nd MCL rank and carries out random access;

If the first MCL rank and the 2nd MCL rank be not identical, the period is read if the mobile access equipment The information of SIB2 (SystemInformationBlockType2, system message 2), adaptively selected new covering grade access The base station.
