In long evolving system, different terminals sends the uplink scheduling information report to the base station under timer or Event triggered.Described uplink scheduling information report mainly comprises buffer status reporting and power headroom report etc.After the base station receives report,, be the terminal distribution channel resource, make the user send data and control information at Uplink Shared Channel UL-SCH according to the available resources of described report content and base station.In order to reduce the expense of reporting uplink schedule information, (system is according to radio bearer (the Radio Bear of terminal correspondence for Buffer Status Report, up transmission BSR) to Buffer Status Report, RB) priority is divided into groups, and reports to the base station by group.
State in realization in the process of the up transmission of BSR, the inventor finds that there are the following problems at least in the prior art: in the radio resource control connection reestablishment process, terminal does not receive and connects during the reconfiguration message, system can suspend except that Signaling Radio Bearer 1 (Signaling Radio Bearer 1, SRB1) other RB in addition, the data of described RB can be buffered in bearing bed.Behind system restoration RB, four kinds of trigger conditions that the discontented football association of terminal view 36.321 proposes, can not send BSR request allocation of channel resources may to the base station at once, the data that are buffered in bearing bed can not in time be sent, can cause bearing bed buffer area data to be overflowed or timer then abandons data in buffer, cause data in buffer to lose.
Summary of the invention
In order to solve existing problem in the above-mentioned prior art, the present invention proposes a kind of method, device and communication system that triggers buffer state report.
A kind of method that triggers Buffer Status Report BSR comprises:

Method, device and the communication system of the triggering buffer state report that the embodiment of the invention provides, by with in the controlled in wireless connection reconstruction process, sending buffer state report in the RB that recover to hang has solved after RB recovers from suspension status in the prior art, fail in time to obtain the problem that ascending resource causes loss of data, make terminal in time trigger report, obtain ascending resource, guarantee that data transmit in time.
Description of drawings
Fig. 1 is the flow chart that triggers the method for Buffer Status Report in the embodiment of the invention;
Fig. 2 is the structure drawing of device that triggers Buffer Status Report in the embodiment of the invention.
Embodiment
Below in conjunction with specific embodiments and the drawings the present invention is further explained.
For after solving in the prior art RB and recovering, fail in time to obtain the problem that ascending resource causes loss of data, the embodiment of the invention provides method, the device of a kind of BSR of triggering.
The method of the triggering BSR that the embodiment of the invention is provided describes in detail below, referring to Fig. 1:
101, terminal can trigger RRC (Radio Resource Control, Radio Resource control) connection reconstruction when following four kinds of scenes, is respectively:
Terminal detects Radio Link and runs into fault;
Terminal is carried out the cell switch process failure;
Terminal is received the integrity protection failure indication that bottom sends;
Controlled in wireless connects the reconfiguration course failure.
When running into one of described scene, terminal MAC (the Media Access Control that resets, the medium access control) layer, and rebulid RLC (Radio Link control) layer of terminal RB, specifically comprise the data of removing original MAC and rlc layer, recover MAC and the original configuration parameter of rlc layer, separately the timer of resetting etc.
After finishing described operation, terminal is reselected the sub-district and is inserted, and sends RRC connection reconstruction request message to eNB (Evolved Node B, the base station of evolution) by SRB0.
102, after the reconstruction request of eNB receiving terminal, send RRC connection reconstruction message to terminal.
After terminal receives described RRC connection reconstruction message; according in the message with RB configuration information recovery SRB1 (Signalling Radio Bearer 1; signaling RB1) connection status; and the security configuration of activated terminals again; described security configuration comprises integrity protection and cryptographic algorithm, hangs other RB except that SRB1 simultaneously.
After finishing described operation, terminal is sent out the RRC connection reconstruction to eNB and is finished message.
103, after the eNB reception is rebuild and finished message, send the RRC reconfiguration information to terminal.
Terminal receives described RRC and connects reconfiguration message, according to the connection status of RB configuration information recovery in the message or modification RB, the suspension status of cancellation RB.
