here, physical resource different principle on subframe in the base station according to each SPS business is each SPS business configuration physical resource, like this, each SPS business of UE will be used the physical resource on different subframes, that is to say, the logic channel that each SPS business is used is with difference, utilize this characteristics, by increasing described SPS service logical channels sign in the authorization messages that sends in the base station, UE is identified according to the SPS service logical channels in authorization messages, distinguish authorization messages and be for the mandate of which SPS business from the physical resource of current maintenance and be configure first or reconfigure, configuration and the maintenance of realization to the physical resource of each SPS business.
Particularly, when realizing this step, the binding relationship of the physical resource of the Logic Channel Identifier of respectively authorizing the SPS business and its mandate need to be preserved in the base station, in order to distinguish the physical resource of each SPS business, and then can be each SPS business configuration physical resource according to physical resource different principle on subframe of each SPS business.
step 102, when described authorization messages is the physical resource configuration messages of SPS business, described UE judges the corresponding physical resource of described SPS service logical channels sign that whether exists in the physical resource of authorizing the SPS business of current maintenance in described authorization messages, if there is no, described UE judges that described authorization messages is used for the SPS business is carried out the configuration first of physical resource, determine the physical resource that described authorization messages is authorized, and determined physical resource and described SPS service logical channels sign are bound, if exist, judge that described authorization messages is used for the SPS business is carried out reconfiguring of physical resource, determine the physical resource that described authorization messages is authorized, when determined physical resource comes into force, remove the current physical resource of having bound of described SPS service logical channels sign, with determined physical resource and the binding of described SPS service logical channels sign, when described authorization messages is the physical resource release message of SPS business, existed the described SPS service logical channels in described authorization messages to identify corresponding physical resource in semi-static physical resource if described UE judges authorizing of current maintenance, the physical resource of described SPS service logical channels sign being bound discharges.
Here, the physical resource configuration messages of described SPS business is HS-SCCH type2 message or E-AGCH type2 message, and the physical resource release message of described SPS business is HS-SCCH orderTypeA message or E-AGCH order message.
In actual applications, can according to the interval of default mandate time and mandate entry-into-force time, determine the physical resource of authorizing in authorization messages.Wherein, the mandate time is that the base station is the time that the SPS business is authorized, and authorizing the entry-into-force time is the first operable time of physical resource of this mandate, the method for the physical resource of specifically authorizing in definite authorization messages, by those skilled in the art are grasped, do not repeat them here.
In this step; at the UE place, SPS service logical channels sign and corresponding physical resource are bound; so that physical resource specified when UE can utilize each SPS service authorization in subsequent step carries out the transmission of data; thereby can guarantee the validity of the Resource Distribution and Schedule of base station side, improve the transmission quality of SPS business.
Step 103, for each SPS business of described UE, the physical resource that described UE utilizes SPS service logical channels sign corresponding to each SPS business to bind carries out the transmission of corresponding SPS business datum.
The schematic diagram of Fig. 2 in the mode of subframe, the SPS business being authorized is described further above-described embodiment below in conjunction with Fig. 2.
In Fig. 2, T1 is the interval of default mandate time and mandate entry-into-force time.According to interval T, authorize SPS ID 1 and first to authorize the configuration of the first physical resource that SPS ID 2 carries out for SPS business 1 and SPS business 2 respectively, wherein authorizing the cycle of the Resource Block that SPS ID 1 configures is 4 subframes, and first authorizes cycle 2 subframes of the Resource Block that SPS ID 2 configures; And second to authorize SPS ID 2 are reconfiguring of the physical resource that carries out for SPS business 2, the physical resource of the SPS business 2 of distributing is before reconfigured constantly from i+T1+T1, changed resource block size and cycle (namely changing 4 subframes into by 2 subframes) that SPS business 2 is used.And the physical resource that reconfigures come into force after the semi-static resource of original SPS business 2 of (namely constantly beginning later from i+T1+T1+1) with no longer valid.
