Description
Technical field
The present invention relates to communication technical field, particularly relate to transfer of data restoration methods, terminal and system in a kind of LTE network.
Background technology
At Long Term Evolution (Long Term Evolution, be called for short LTE) in network, after subscriber equipment (UE) i.e. accessing terminal to network system, to initiate transfer of data, need first to send a dispatch request (SR) to base station, terminal can utilize ascending control channel transmission dispatch request to distribute uplink shared channel resources to base station requests, after base station receives this dispatch request, when there being upstream data pending, distributing uplink shared channel resources to terminal, carrying out transmitting uplink data for terminal.
Base station is before Resources allocation carries out transmitting uplink data to terminal, wireless distribution message (RRC) can be sent to terminal, wireless distribution message is carried and has been issued scheduling request resources configuration information and measurement clearance (GAP) resource allocation information, for the position of the transmission position and measurement clearance resource of determining scheduling request resources.
Dispatch request configuration index I is mainly comprised in scheduling request resources configuration information
sR, dispatch request transmission cycle and subframe position thereof are by configuration index I
sRdetermine, specific formula for calculation is as follows:
（10×SFN+subframe-N
OFFSET,SR）modSR
Periodicity=0
Wherein, SFN is the System Frame Number that dispatch request sends, and subframe is that dispatch request sends subframe numbers, N
oFFSET, SRfor dispatch request sub-frame offset, SR
periodicityfor dispatch request sends the cycle, can by the configuration index I in such as following table 1
sRobtain.
Table 1
Measurement clearance resource is to support that different frequency/different standard is synchronous and measuring and the resource of definition in LTE network.Terminal, once enter measurement clearance resource time, will not allow any up-downgoing transmission.Measurement clearance resource has two kinds of cyclic patterns, and the cycle is respectively 40ms and 80ms, and the measurement clearance resource allocation information issued by base station determines to adopt which kind of pattern.No matter which kind of cyclic pattern measurement clearance resource duration is all fixed as 6ms.Measurement clearance resource allocation information mainly comprises measurement clearance resource period, measurement clearance resource sub-frame offset gapoffset etc., the original position of measurement clearance resource calculates according to the measurement clearance resource period in measurement clearance resource allocation information, measurement clearance resource sub-frame offset gapoffset, and specific formula for calculation is as follows:
SFN?mod?T?=?FLOOR(gapoffset/10)；
subframe?=?gapoffset?mod?10；
Wherein, T is 1/10th, SFN of measurement clearance resource period is measurement clearance resource starter system frame number, and subframe is measurement clearance resource initial subframe number.SFN and subframe determines the original position of measurement clearance resource jointly.
The scheduling request resources that base station sends to terminal with inevitably there is the situation occurring conflicting between measurement clearance resource, as being 80ms when measurement clearance resource period, measurement clearance resource sub-frame offset gapoffset=0, dispatch request configuration index I
sRwhen=78, the system frame number SFN mod 8=0 of measurement clearance resource is obtained according to above-mentioned formulae discovery, the initial subframe of measurement clearance resource is subframe 0, no matter again because which kind of cyclic pattern of measurement clearance resource duration is all fixed as 6ms, then measurement clearance resource takies these 6 subframes of subframe 0 ~ subframe 5 altogether.
And by the table of comparisons 1, the transmission cycle of dispatch request is also 80ms, then according to computing formula, the system frame number SFN mod 8=0 that dispatch request sends, dispatch request sub-frame offset N
oFFSET, SR=I
sR-75=3, then dispatch request transmission subframe is the 3rd subframe is also subframe 3.
As from the foregoing, the System Frame Number of dispatch request is identical with the System Frame Number of measurement clearance resource (being 0), and the transmission subframe of dispatch request is subframe 3, drop in the scope of subframe 0 ~ subframe 5 of measurement clearance resource occupation, then the transmission position of scheduling request resources overlaps with the position of measurement clearance resource.
Terminal is once enter measurement clearance resource time, any up-downgoing transmission will not be allowed, and overlap with the position of measurement clearance resource due to the transmission position of scheduling request resources, cause terminal that ascending control channel cannot be utilized to send dispatch request, also Uplink Shared Channel just cannot be utilized to carry out the transmission of any data, and then data cannot be received at carrier frequency residing for Serving cell, cause data-transmission interruptions.

8. terminal according to claim 7, it is characterized in that, described sending module specifically for: when analyzing the transmission position of scheduling request resources and overlapping with the position of measurement clearance resource, start a timer and carry out timing, and the abnormal wireless distribution that transmission comprises information completes message to described base station; Described recovery module specifically for: when the transmission position by described renewal wireless distribution message computational analysis scheduling request resources no longer overlaps with the position of measurement clearance resource, stop and resetting described timer, and according to the transmission location restore transfer of data of scheduling request resources upgraded.
9. terminal according to claim 8, is characterized in that, described recovery module also for:
When the transmission position by described renewal wireless distribution message computational analysis scheduling request resources still to overlap with the position of measurement clearance resource or described timer time reach Preset Time also do not receive described renewal wireless distribution message time, re-establish the connection of terminal and base station.
10. the transfer of data recovery system in LTE network, is characterized in that, comprising: terminal and base station, wherein,
Described terminal, carries out computational analysis for the scheduling request resources configuration information that sent by wireless distribution message according to the base station received and measurement clearance resource allocation information; When the transmission position analyzing scheduling request resources overlaps with the position of measurement clearance resource, send the abnormal wireless distribution comprising information and complete message to described base station; Receive base station completes message transmission renewal wireless distribution message according to described abnormal wireless distribution, and according to described renewal wireless distribution message recovery transfer of data;
Described base station, for being sent scheduling request resources configuration information and measurement clearance resource allocation information extremely described terminal by wireless distribution message, when the abnormal wireless distribution comprising information receiving the transmission of described terminal completes message, configuration is re-started to scheduling request resources and measurement clearance resource, and send renewal wireless distribution message to described terminal, for described terminal resume data transmission.
