The method comprises the steps: a control plane of a base station fragments SI in which a system information block (SIB) is located, and transmits all the acquired SI fragments and related information thereof to a user face of the base plane of the base station; the user plane groups all the SI fragments into an SI fragment transmission queue according to an index value, for indicating the sequence of SI contents, in the relevant information; and the user plane transmits the SI fragments to UE (User Equipment) according to the SI fragment transmission queue. According to the invention, by means of transmitting all the SI fragments and the relevant information thereof of the SIB to the user plane by the control plane and grouping the SI fragment transmission queue to carry out SI fragment transmission by the user plane under the condition that adjacently transmitted SI fragments are not repeated, the UE can receive all the SI fragments of the SIB rapidly and completely, the latency time for recombining the SI fragments is reduced, and the advantages of higher efficiency, timely information response and good user experience effect are achieved.
Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of Long Term Evolution (Long Term Evolution, LTE) system information (System Information, SI) burst dispatching method and system.
Background technology
The LTE system can carry out the transmission of broadcast message, the broadcast message of being sent comprise host system message block (Master Information Block, MIB) and system information block (System Information Block; SIB), wherein, SIB comprises SIB1, SIB2 and other SIB etc.; Except SIB1, other SIB all be the form with SI send to user terminal (User Equipment, UE); When sending SI if the SI that sends is bigger; Will carry out fragment process to the SI that will send, be divided into several small data groups and send to UE, this SI is divided into the small data group is exactly the SI burst; And UE must wait until all SI bursts collect finish after, just can parse the content of SI.
In the prior art, the realization flow of LTE system information burst scheduling is as shown in Figure 1, comprising:
Step 101～step 102, the chain of command of base station carries out burst with SI, and issues a SI burst A in a modification cycle (modification period), for the user plane of base station;
Step 103, user plane repeat to send this SI burst A in this modification cycle;
Step 104, in the next one modification cycle, chain of command issues another one SI burst B and gives user plane;
Step 105, user plane are sent this SI burst B in this modification cycle.
For the processing meeting of SI burst set by step 101～105 realization flow carry out so always.
And for UE, UE can receive the SI burst of repetition in a modification cycle; UE is for the SI burst of recombinating; Need to wait for that several revise cycle time, and taking place to have SIB11, SIB12 etc. in the system information under the situation such as seismic sea wave, transmission business information; And SIB11, SIB12 are bigger in this case, need carry out burst to the SI at SIB11, SIB12 place; And then UE need wait for that several modification cycles can receive complete all SI bursts, and transmitting efficiency is lower, and the base stations control face all will issue the SI burst to user plane in each modification cycle, causes the burden of base station processes SI heavier; UE carries out SI burst reorganization time also can postpone a period of time, and through giving the user to use again after the high-rise reorganization, can influence user's response timely fast, influences user's experience.
