Fig. 1 shows the uplink channel structure of business subband;
Fig. 2 shows the distribution method of the SR resource according to the embodiment of the present invention;

Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail.
In the broadband access system based on TD-LTE technology, system bandwidth is divided into multiple continuous or discrete subband, is further divided into synchronous subband and business subband according to function.Synchronous subband is used for system broadcasts and synchronization, and Physical Broadcast Channel (PBCH), downlink synchronous signal (PSS/SSS) and uplink random access channel (PRACH) are operated in synchronous subband; Business subband is used for business transmission, and the up channels such as the down channels such as such as Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Control Format Indicator Channel (PCFICH) and physical mixed indicating channel (PHICH) and such as dispatch request (SR, Schedule Request), Physical Uplink Control Channel (PUCCH) and Physical Uplink Shared Channel (PUSCH) are all operated in business subband.
For reducing costs and implementation complexity, UE can be operated in list band model, and namely the receiver bandwidth of UE needs not to be whole system bandwidth, and UE is operated in all or part of subband according to the different choice of hardware capabilities, and the most weak UE of ability is only operated in list band.For supporting that UE is operated in list band model, system has following feature: 1. synchronous subband and business subband are all discrete list bands; 2. business transmission adopts semi-static transmission means, is taken or releasing resource by explicit unlatching mandate and closedown mandate; 3., when UE exists up-downgoing business simultaneously, up-downgoing business must be transmitted on same business subband.
For ensureing that terminal has the ability of active reporting and full duplex, system is that the reserved ascending control channel of each terminal is for initiating dispatch request (SR).If terminal has data arrive and do not have ascending resource, then trigger SR and start to monitor PDCCH, before obtaining distributing the mandate of Uplink Shared Channel (UL-SCH) resource for new data transmission, UE initiates SR by all resource locations can initiating SR.
Fig. 1 shows the uplink channel structure of business subband.As shown in Figure 1, each business subband reserves the position that fixing ascending resource is asked as SR.For supporting magnanimity terminal online, take the mode of fixed allocation SR resource, suppose each business subband has M SR resource in 1 SR cycle, SR resource Further Division is: first kind SR resource M1, the user high for service priority or delay requirement is high, requires have twice chance to send SR in 1 minimum period; Equations of The Second Kind SR resource M2, for domestic consumer, in 1 cycle, once chance can send SR; Remain M-M1-M2 SR resource, keep for fast dispatch user Interim use, namely return to the residence sub-band of distribution after user's end of transmission and discharge busy SR resource.Like this, each business subband at most can resident N number of user, and N is less than or equal to M, usually, and the user that domestic consumer's number is high higher than service priority or delay requirement is high.When access customer number reaches the maximum resident users number of whole business subband, system resource allocation is more difficult, and for ensureing system stability work, need to leave certain redundancy, usually, the system maximum number of user of setting is less than or equal to business sub band number * N.
Fig. 2 shows the distribution method of the SR resource according to the embodiment of the present invention, and this distribution method comprises:
Step S201: the random access lead code that receiving terminal is initiated;
Step S202: search the subband with unappropriated SR resource, if exist, enters into step S203, if do not exist, enters into step S206;
Step S203: send accidental access response, and the subband that a unappropriated SR resource is maximum is selected in the subband with unappropriated SR resource, distributed the residence sub-band as terminal;
Step S204: receive RRC connection establishment request message;
Step S205: in RRC connection establishment message, distributes the SR resource of place residence sub-band; And
Step S206: do not send accidental access response, i.e. random access procedure failure, waits for that terminal initiates random access lead code again.
Be according to the SR resource allocation methods of the embodiment of the present invention and the difference of SR resource allocation methods of the prior art: will judge whether to there is the subband with unappropriated SR resource according to the SR resource allocation methods of the embodiment of the present invention after base station receives the random access lead code that receiving terminal initiates, if do not exist, do not send accidental access response, namely represent random access procedure failure, terminal can initiate Stochastic accessing again; And unlike in the prior art, when waiting until that transmission RRC connection establishment message (Msg4) finds SR inadequate resource when distributing SR resource, just refuse the Stochastic accessing of terminal, thus decrease unnecessary access delay always.
Particularly, Fig. 3 shows searching and distributing the flow chart of the method for residence sub-band according to the embodiment of the present invention, and the method comprises:
Step S301: search the subband that up-downgoing resource is all idle.The subband that up-downgoing resource is all idle, when distributing residence sub-band, is searched in base station in sub band resources, if exist, enters into step S302, if do not exist, does not then send accidental access response, namely represents random access procedure failure.
Step S302: search unappropriated Equations of The Second Kind SR resource at most and still have the subband of unappropriated first kind SR resource.If exist, then enter into step S305, if do not exist, then have following three kinds of situations:
1) there is unappropriated Equations of The Second Kind SR resource but there is not the subband of unappropriated first kind SR resource, for this situation, entering into step S303;
2) there is not unappropriated Equations of The Second Kind SR resource but there is the subband of unappropriated first kind SR resource, for this situation, entering into step S304;
3) neither there is the subband that unappropriated Equations of The Second Kind SR resource does not exist unappropriated first kind SR resource yet, namely the SR resource of all subbands is all assigned, then do not send accidental access response, represents random access procedure failure.
Step S303: search the subband that unappropriated Equations of The Second Kind SR resource is maximum, then enter into step S305.
Step S304: search the subband that unappropriated first kind SR resource is maximum, then enter into step S305.
Step S305: send allocation of subbands that accidental access response the selects unappropriated SR resource maximum residence sub-band as terminal, namely for step S302, select a unappropriated Equations of The Second Kind SR resource at most and still have the subband of unappropriated first kind SR resource; For step S303, select the subband that a unappropriated Equations of The Second Kind SR resource is maximum; For step S304, select the subband that a unappropriated first kind SR resource is maximum.
According in the SR resource allocation methods of the embodiment of the present invention, the SR resource of place residence sub-band is distributed in base station when RRC connection establishment message (Msg4), default allocation Equations of The Second Kind SR resource, only have when the complete and first kind SR resource of Equations of The Second Kind SR Resourse Distribute still has residue, just can go to distribute first kind SR resource.
After the SR resource for terminal distribution, base station receives RRC connection setup complete message (Msg5), carry out call access control.Now, service quality (QoS) information from core net can be known in base station, and this QoS information comprises the type of service of terminal.Now, there is following several situation:
1) if terminal is domestic consumer, and the SR resource of original allocation is Equations of The Second Kind SR resource, then say user admission success from the angle of SR resource, and base station is follow-up can initiate security activation and RRC connection reprovision.
2) if terminal is domestic consumer, and the SR resource of original allocation is first kind SR resource, then represent that Equations of The Second Kind SR resource distributes, this user can not be accepted, and RRC Connection Release is initiated in base station.
3) if the terminal user that to be priority high or delay requirement is high, and the SR resource of original allocation is Equations of The Second Kind SR resource, and now first kind SR resource still has residue, then say user admission success from the angle of SR resource, base station is follow-up can initiate security activation and RRC connection reprovision, and in reallocation message, redistributes first kind SR resource to this user; Otherwise just can not receive this user, base station release RRC connects.
4) if the terminal user that to be priority high or delay requirement is high, and the SR resource of original allocation is first kind SR resource, then say user admission success from the angle of SR resource, and base station is follow-up can initiate security activation and RRC connects reprovision.
So far, SR Resourse Distribute is complete.
