4）Upstream data is sent；
So that online user carries out transmitting uplink data as an example：
When there is transmitting uplink data, end side judges uplink loss, by random access procedure, completes uplink synchronous； When base station receives random access procedure message during uplink synchronous（Msg）After 3, pass through the cell wireless network of Msg3 carryings Network temporary mark（C-RNTI）The inquiry of online user is carried out, then the user to inquire redistributes PUCCH resource, passes through Reallocation message of eating dishes without rice or wine notifies the PUCCH resource that user distributes, and notifies each layer of base station side.
For the interactive service of small data quantity, such as QQ chats, if Stochastic accessing and real by way of distributing PUCCH Existing data transfer, can frequently trigger online transactivation process, cause the PUCCH resource distribution of table tennis.Due to cell users Excessively, online user can be caused to be distributed without PUCCH resource.
The content of the invention
The embodiment of the present invention proposes a kind of method of data transfer, using message transmission data, can quickly realize data Transmission, avoid the PUCCH resource pingpang handoff of the interactive service of small data quantity.
The technical scheme of the embodiment of the present invention is as follows：
A kind of method of data transfer, methods described include：
When online user transmits upstream data, fixed resource authorization is distributed for the upstream data including group A lead codes, For the upstream data including group B lead codes according to existing resource distribution resource authorization；
Cell Radio Network Temporary Identifier/Identity, Cell-RNTI C-RNTI is carried in the message that terminal is sent on the resource authorization to base station And upstream data；
Base station determines that the reason for online user enters presence is no data transfer according to C-RNTI, receives in message The upstream data of carrying.
It is described that fixed resource authorization is distributed for the upstream data including group A lead codes, for including group B lead codes Upstream data is included by existing resource allocation resource authorization：
The buffer data size and power control that are needed according to upstream data determine the lead code of the upstream data；
For the resource authorization that the upstream data distribution including group A lead codes is fixed, for including the up of group B lead codes Data press existing resource allocation resource authorization.
It is described to include according to existing resource distribution resource authorization：Dispatch situation distribution resource authorization according to existing resource.
Methods described further comprises：
BSR in the message that terminal is sent on the resource authorization to base station；
Base station determines that the reason for online user enters presence is no data transfer according to C-RNTI, is entered according to BSR The distribution of row ascending resource is to transmit upstream data.
Methods described further comprises：
Buffer status report process BSR is carried in the message that terminal is sent on the resource authorization to base station；
After base station receives BSR, determine that the reason for online user enters presence is that SR reaches maximum biography according to C-RNTI Defeated number；
Base station down distributing resource mandate again, distributes physical uplink control channel PUCCH resource, and transmission online user remains Remaining upstream data.
Methods described further comprises：
Base station determines that the reason for online user enters presence is that SR reaches maximum transmission times according to C-RNTI, and BSR is not carried in the message sent on the resource authorization to base station；
Base station carries out the downlink resource mandate of message 4.
From above-mentioned technical proposal as can be seen that when online user transmits upstream data in embodiments of the present invention, for The fixed resource authorization of upstream data distribution including group A lead codes, for including group upstream data of B lead codes according to existing Resource allocation resource authorization；C-RNTI and upstream data are carried in the message that terminal is sent on the resource authorization to base station； Base station determines that the reason for online user enters presence is no data transfer according to C-RNTI, receive carried in message it is upper Row data.Because terminal transmits upstream data in the message 3 sent to base station, data transfer can be quickly realized, is avoided small The PUCCH resource pingpang handoff of the interactive service of data volume.
Brief description of the drawings
Fig. 1 is the method flow schematic diagram of data transfer.
Embodiment
It must be more clearly understood to express the object, technical solutions and advantages of the present invention, below in conjunction with the accompanying drawings and specifically The present invention is further described in more detail for embodiment.
In embodiments of the present invention, user by message 1, message 2, message 3 and disappears with base station during uplink synchronous Breath 4 carries out uplink synchronous.The message 3 that UE is sent to eNB during uplink synchronous is made full use of, due to the data volume of small data quantity Less feature thus in message 3 carry user upstream data, and and non-used PUCCH resource application ascending resource transmit The upstream data of user, and then cause PUCCH resource pingpang handoff the characteristics of avoid the interactive service of small data quantity.
It is the method flow schematic diagram of data transfer referring to accompanying drawing 1, specifically includes following steps：
101st, packet
Online user determines line number on this when there is transmitting uplink data, according to the buffer data size of upstream data and power control According to group A or group B is belonged to, and identified again in the lead code of upstream data.Packet belonging to upstream data is distinguished with lead code. Wherein, the buffer data size and power control determination group A and group B according to upstream data are prior arts.
102nd, resource authorization
The group A or group B of lead code are distinguished in base station in the random access procedure, carry out the resource allocation of message 2.Base station according to Intrinsic dispatching principle distributes group A fixed resource authorization；Awarded for group B by the dispatch situation distribution resource of existing resource Power.The process of the distribution resource authorization is prior art.
103rd, data transfer
Whether terminal carries BSR after the message 2 of base station transmission is received according to buffer data size decision message 3.If This data transfer can realize all data cached transmission, then the transmission unit for directly generating C-RNTI+ data is transmitted； If this can not realize all data cached transmission, buffer status report process is carried（BSR）That is C-RNTI+BSR+ numbers According to transmission unit.BSR is used to provide the UE data amount informations for caching awaiting transmission up at present to service eNB.
104th, data are received
Base station splits protocol element after receiving message 3, receives the upstream data carried in message 3.
105th, the reason for judging to enter presence, data are transmitted.
The reason for judgement enters presence.If being there is no data transfer for a long time into the reason for presence, and disappear BSR is not carried in breath 3, illustrates the data transfer ends.Such case meets the situation of small data quantity burst transfers of data, then not PUCCH resource and SRS resource are distributed, but utilizes message 3 to transmit upstream data.
If being there is no data transfer for a long time into the reason for presence, and BSR is carried, then eNB reports according to terminal BSR carry out ascending resource distribution to transmit the response message of upstream data and allocation of downlink resource transmission message 3（That is message 4）；The BSR carried afterwards according to each upstream data distributes the resource authorization of transmitting uplink data, until all upstream datas pass It is totally lost into.If being that SR reaches maximum transmission times into the reason for presence, illustrate that wireless environment is bad, therefore can not determine Whether it is the transmission of burst small data business, it is necessary to which eNB distributes PUCCH resource to ensure to be adapted to all traffic performances.
If being that SR reaches maximum transmission times into the reason for presence, BSR is carried in message 3, then is illustrated on also Row data need to transmit, and eNB distribution PUCCH resource configurating terminals, realize the process of the online transactivation of user, transmit remaining Upstream data.
If being that SR reaches maximum transmission times into the reason for presence, and without BSR is carried, then only carry out message 4 Downlink resource mandate.The foregoing is only a preferred embodiment of the present invention, is not intended to limit the protection model of the present invention Enclose.Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention Protection domain within.
