Embodiment 1
See also Fig. 2, Fig. 2 comprises the steps: for the method flow schematic diagram that an embodiment provides
Step S201: mobile station MS receives the uplink scheduling sign USF from network side.
Step S202: the USF that determine to receive the whether temporary up-link block flow TBF of instruct MS connects the grouped channels that takies and is in idle condition.
If connecting the grouped channels that takies, the TBF of USF instruct MS is in idle condition, execution in step S203.
Step S203: be in idle condition if the up TBF of the USF that receives indication connects the grouped channels that takies, and MS has and needs the grouping busihess data that sends, MS to connect to network side by up TBF to send grouping busihess data.
USF is that network side is used to dispatch the sign that next scheduling of MS sends the upstream packet business datum constantly, sends to MS by current scheduling downlink data block constantly.
If next scheduling of MS does not constantly need the upstream packet business datum that sends, network side is set to free value with the value of the USF that carries in current scheduling downlink data block constantly, represent that next scheduling corresponding to this USF sends the upstream packet business datum without MS constantly, the TBF of MS connects the grouped channels that takies and is in idle condition.As an example, this free value can be 7.
If MS has new grouping busihess data to need to send, whether the value of the USF that detection receives indicates TBF to connect the grouped channels that takies is in idle condition, if grouped channels is in idle condition, this MS can initiatively send the upstream packet business datum to network side, and need not to wait for the scheduling of network side.
In the present embodiment, grouping busihess data refer to TBF that carry with data traffic aided.
Further, the method that the present embodiment provides can also comprise step 204.When step 202 judgement USF indication grouped channels is occupied, execution in step 204.
Step S204 judges the whether value of corresponding MS of value that USF carries, and if so, execution in step S205, send ascending packet data, and if not, execution in step 201.
The method that the present embodiment provides, when MS detects TBF that USF indicates this MS and connects the grouped channels take and be in idle condition, if MS has the upstream packet business datum to need to send, can need not to wait for the scheduling of network, and initiatively send the upstream packet business datum, thereby can take full advantage of channel resource, reduce the time delay that upstream data sends.
Further, the method that the present embodiment provides can also be applied to be in the MS of delayed release state, when having new needs to send grouping busihess data with the MS that reduces the delayed release state, reduces transmission delay.
Embodiment 2
See also Fig. 2, Fig. 2 comprises the steps: for the method flow schematic diagram that another embodiment provides
Step 301:MS sets up up TBF with network side and is connected.
When MS has the upstream packet business datum that need to send to network side, need to set up up TBF with network side and be connected.
A TBF connects shared channel resource, can be shared by a plurality of MS.Network side distributes a sign for each MS, and the up TBF that carries this sign scheduling MS by USF connects.This USF sign can connect the data block that sends by descending TBF and carry.
Step 302: network side arranges USF in downlink data block, and the up TBF that dispatches each MS connects.
Different MS has different USF signs, and network side connects by the up TBF that each MS of this sign scheduling is set in USF.And MS monitors the USF from network side, if monitor the USF that the USF of network side is oneself, to uplink scheduling that should USF constantly, connects by up TBF and sends the upstream packet business datum.
Step 303: after grouping busihess data sent, MS entered up delayed release state.
Enter the MS of delayed release state, its TBF connects will be in inactive pattern, and the TBF that is under this state connects, and can only need the less conservation of resources.
Step 304: when not needing the TBF that dispatches to connect, putting USF when network side sends downlink data block is free value.
As, when multiplexing all TBF connections at same channel, the upstream packet business datum that all need not send, this grouped channels is in idle condition, and network side is free value at the mid-USF of downlink data block.
And this free value can be 7.Other value can certainly be set, depend on the regulation of agreement.
Step 305: MS has new grouping busihess data to send under the delayed release state, and the USF that receives simultaneously is free value, initiatively sends the upstream packet business datum.
For example, under the delayed release state, a USF value that receives as MS initiatively sends the upstream packet business datum during for free value.
Perhaps, when the value of the USF more than 2 that receives continuously as MS all is free value, just send the upstream packet business datum, avoid a plurality of MS to send data simultaneously and cause collision.In an embodiment, the USF more than 2 refers to more than or equal to 2 USF.
And MS can send the upstream packet business datum constantly in scheduling corresponding to the USF that receives free value; Perhaps, be free value if receive a plurality of USF, an in the end scheduling corresponding to USF sends the upstream packet business datum constantly.
In order to further illustrate the above embodiments, please participate in Fig. 3, Fig. 3 has provided a kind of concrete application scenarios of the present embodiment:
At same grouped channels, multiplexing 3 up users' MS (MS1, MS2 and MS3), the value of its USF is respectively Isosorbide-5-Nitrae, and 5; And if USF=7 represents idle condition, these 3 MS all need to send without grouping busihess data.
Each MS sends the upstream packet business datum according to the scheduling of network side.For example, when USF=4, MS2 sends uplink data block Block1, Block2 and Block6 constantly at the uplink scheduling of correspondence; During USF=1, MS1 sends uplink data block Block3 and Block8 constantly at the uplink scheduling of correspondence.
When each MS sends the upstream packet business datum, each MS will enter the delayed release state.For example, the MS of USF=1, when Block8 was corresponding, upstream data sent, and entered the delayed release state; The MS of USF=4 is in time corresponding to Block6, and upstream data sends, and enters the delayed release state; The MS of USF=5 is in time corresponding to Block5, and upstream data sends, and enters the delayed release state.
In time corresponding to Block9, because having MS, network side to not send the information of upstream packet business datum, USF corresponding to this uplink scheduling moment is set to free value 7, Block10, the scheduling that Block11 is corresponding is constantly also like this.
In the moment corresponding to Block9, each MS does not have the upstream packet business datum, does not send the upstream packet business datum; Still like this during Block10.In the moment corresponding to Block11, the MS of USF=5 has new upstream packet business datum to send, and discovery USF is FREE, initiatively sends the upstream packet business datum in the moment corresponding to Block11.
In the method that the present embodiment provides, MS if only have the grouping busihess data that a MS has needs transmission, can initiatively send grouping busihess data after receiving the USF of indication grouped channels for the free time.
If having, a plurality of MS need to send grouping busihess data, between each MS, same channel resource is used in competition, thereby cause data to send unsuccessfully, network side can be judged the data that MS has needs to upload according to the data that send, and dispatches MS by USF and resends data; Perhaps, if the data head that network side can the resolution data bag can send data according to the message scheduling MS of data head.
The method that the present embodiment provides can reduce the stand-by period that MS under delaying state sends data, has improved efficiency of transmission.
Embodiment 3
Step 401:MS sets up up TBF with network side and is connected.
Step 402: network side connects at the mid-USF dispatching uplink of downlink data block TBF.
Step 403: if the USF of network side setting is the USF of oneself, MS is sending uplink data block constantly to uplink scheduling that should USF.
Step 404: after the grouping busihess data of MS sent, network side stopped dispatching this TBF and connects.
Step 405: if the up TBF that need not dispatch connects, putting USF when network side sends downlink data block is free value.
Step 406:MS continues to monitor USF, determines according to USF whether grouped channels is idle.
If the value of 1 USF that MS receives is free value, determine that grouped channels is idle; Perhaps, if the continuous USF value more than 2 that MS receives is free value, determine that grouped channels is idle.
If grouped channels is idle, execution in step 407; Otherwise, execution in step 403.
Step S407: if MS has new grouping busihess data to need to send, the scheduling corresponding at USF sends grouping busihess data constantly.
If MS has new grouping busihess data to send, be the scheduling moment corresponding to free value at USF, initiatively send the upstream packet business datum.If there is no new grouping busihess data, do not send.
For example, 4 USF that are consecutively detected same time slot as MS are free value, and an in the end scheduling corresponding to USF sends the upstream packet business datum constantly.
The method that the present embodiment provides if MS has the data that need transmission, can reduce the stand-by period of MS, does not need the scheduling of network side initiatively to send data, has reduced the stand-by period, has improved efficiency of transmission.
