For example, each available PRACH sequence of cell is 64 in existing LTE system.Base station is wide by system information Logical root sequence index RACH_ROOT_SEQUENCE is broadcast, cyclic shift interval is notified by high-level signaling (zeroCorrelationZoneConfig) parameter (i.e. Ncs).UE first passes through logical root sequence after receiving the two parameters Index finds corresponding physics root sequence u, according to formula0≤n≤N_ZC- 1 generates PRACH root sequence, so Afterwards, different PRACH sequences is obtained according to the cyclic shift that Ncs value carries out different length to PRACH root sequence.If according to receipts The Ncs value arrived, a root sequence cannot generate 64 PRACH sequences, then UE continues to use next logical root sequence index, look for Its corresponding physics root sequence, repeats the above process, until generating 64 PRACH sequences.The sequence of these PRACH sequences Number be 0 to 63.Logical root sequence index is continuously from 0 to 837.

In embodiments of the present invention, corresponding object is found according to logical root sequence index RACH_ROOT_SEQUENCE in base station Root sequence u is managed, according to formula0≤n≤N_ZC- 1 generates PRACH root sequence, then, according to Ncs value pair The cyclic shift that PRACH root sequence carries out different length obtains different PRACH sequences.If according to the Ncs value received, one Root sequence cannot generate 64 PRACH sequences, then UE continues to use next logical root sequence index, look for its corresponding physics root Sequence repeats the above process, and until generating 64+P PRACH sequence, the Serial No. 0 of these PRACH sequences arrives 63+P. Logical root sequence index is continuously from 0 to 837.Wherein, it is the PRACH that D2D equipment is reserved that rear P PRACH sequence, which is base station, Sequence.

D2D equipment finds corresponding physics root sequence u according to the RACH_ROOT_SEQUENCE of base station broadcast, according to formula0≤n≤N_ZC- 1 generates PRACH root sequence, then, carries out different length to PRACH root sequence according to Ncs value The cyclic shift of degree obtains different PRACH sequences, if one root sequence cannot generate 64 according to the Ncs value received PRACH sequence, then UE continues to use next logical root sequence index, looks for its corresponding physics root sequence, repeats the above process, Until generating 64+P PRACH sequence, the Serial No. 0 of these PRACH sequences arrives 63+P.Logical root sequence index is to connect It is continuous from 0 to 837.Wherein, it is the PRACH sequence that D2D equipment is reserved that rear P PRACH sequence, which is base station,.D2D equipment is being realized When D2D function, random access is carried out using rear P PRACH sequence.

Common UE generates 64 PRACH sequences, this 64 PRACH also according to the method that existing LTE system is described above Sequence is not that base station is the PRACH sequence that D2D equipment is reserved.

P value can be the fixed value of an agreement, for example, P=128, is not necessarily to the number by signaling P in this way, from And it saves and signals expense.P value can also be determined according to the size of arranged network, for example, P can be 64 or 128, this When, notice P value can be broadcasted by system information.

Since common UE and D2D equipment all uses PRACH sequence to be accessed, D2D device request accesses LTE net The method of network can request the method for access consistent with LTE UE.If accessed without D2D device request, time-frequency can not be reserved Resource is to D2D user.

Optionally, the public resource in the embodiment of the present invention is for being detected and/or being supervised on the public resource by D2D equipment The information for listening other D2D equipment to send.

Preferably, step 302 can be accomplished by the following way: when meeting preset condition, base station distribution is set for D2D Standby public resource；The preset condition includes at least one of the following: PRACH request is received for the first time from D2D The PRACH of equipment is requested；There is no available public resource when receiving PRACH request；Before receiving PRACH request Not yet distributed public resource；When receiving PRACH request, the last time public resource of distribution has discharged.The public money Source can be public running time-frequency resource, for example, request LTE network is distributed to D2D and set when public running time-frequency resource can be to be initially accessed Standby periodic running time-frequency resource.After obtaining public resource, D2D equipment can detect on the public resource or monitor other The information that D2D equipment is sent.In the present embodiment, realizing base station is that D2D distributes initial public resource.

In addition, being still to be fixed with one every 80ms when there is no D2D equipment or D2D equipment is less in the prior art Subframe is communicated for D2D, therefore there are problems that the wasting of resources.In the present embodiment, can when meeting above-mentioned preset condition, Base station be just include D2D equipment distribution public resource, so as to avoid in no D2D equipment be D2D equipment distribute resource, mention The high efficiency of system.

Preferably, if currently allocated public resource, step 302 can also be realized one of in the following manner:

D2D equipment corresponding to mode one, service condition and PRACH request according to the public resource of last time distribution The public resource for D2D equipment is redistributed in quantity, base station；For example, if it is determined that the public resource of last distribution It is used by D2D equipment, and has new D2D device request access again, then increase the public resource for being used for D2D equipment；If base station is sentenced The inadequate resource being not used by the public resource of disconnected last distribution is then increased with meeting the corresponding D2D equipment of PRACH request Add the public resource for D2D equipment；If the utilization rate of the public resource of the last distribution of base station judgement is very low, and receives The corresponding D2D equipment of PRACH request quantity it is smaller, then reduce the public resource for being used for D2D equipment.When D2D equipment connects After entering successfully, base station can distribute private resource to the D2D equipment from public resource.If the base station find that distributing to some D2D The private resource of equipment is not used by the given time, then discharges the resource.Therefore, base station can be obtained by way of monitoring Obtain the service condition of public resource.

Mode two, the quantity of D2D equipment according to the size of the public resource of last time distribution, currently accessed and should The quantity of the corresponding D2D equipment of PRACH request, the public resource for D2D equipment is redistributed in base station.For example, if base Resource needed for D2D equipment corresponding to the D2D equipment and PRACH request that judgement has currently accessed of standing is greater than last distribution Public resource size, then can increase the public resource for D2D equipment；It is on the contrary, it is possible to reduce the public affairs for D2D equipment Resource altogether.

By above two mode, base station is according to the quantity of the corresponding D2D equipment of PRACH request and last point The service condition for the public resource matched neatly can distribute public resource for D2D equipment, be accessed with the current needs of satisfaction The needs of D2D equipment, even if each D2D equipment can still obtain corresponding resource in this way, D2D equipment is more.

Preferably, base station can also be according to the number of the PRACH sequence received, and dynamic adjusts the size of public resource, Then, base station can notify public resource adjusted to give D2D equipment.When the PRACH sequence received is more, base station can Think that D2D equipment distributes biggish public resource, when the PRACH sequence received is less, base station can be distributed for D2D equipment Lesser public resource.For example, base station is D2D equipment distribution first when receiving the first PRACH sequence from D2D equipment Public resource, when the number of the PRACH sequence received is more than first threshold, base station is that D2D equipment distributes the second public money Source, the second public resource are bigger than the first public resource.In the related art, a subframe is fixed with every 80ms to lead to for D2D Letter, if D2D equipment is more in network, is not able to satisfy demand of the D2D equipment to resource.Method through this embodiment, root According to the number of the PRACH sequence received, base station dynamic adjusts the size of public resource, when the PRACH sequence received is more When, the resource for the distribution of D2D equipment can be increased, to meet the needs of D2D equipment is to resource.

It optionally, after step 302, can also include step 303, public money of the base station to the notice distribution of D2D equipment The information in source, for example, base station is periodically to the information of the public resource of D2D equipment notice distribution, base station is in a broadcast manner The information of the public resource of its local D2D equipment distribution of periodic notification.The public resource can be total for all D2D equipment With for searching for the information of other D2D equipment.For example, the D2D equipment of application resource is by the D2D device code code information of oneself It is sent on the public running time-frequency resource.D2D equipment carries out on the running time-frequency resource position after obtaining running time-frequency resource location information Search, if it find that other D2D equipment, then find success.Through this embodiment, D2D equipment can know the public money of distribution Source, to detect and/or monitor the information of other D2D equipment transmission using the public resource.

Preferably, notify the position of public resource that can realize at least one in the following manner:

The information for the public resource that base station can be distributed by control signaling to the D2D equipment of activated state notice.For example, right In the UE of activation (Active) state, it can default using 10ms as the period, that is, the position notified every time is a radio frames (10ms) Interior available running time-frequency resource, every 10ms pass through Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) notify a running time-frequency resource.

The information for the public resource that base station is distributed by common signaling to the D2D equipment of Idle state notice.For example, for sky The UE of not busy (idle) state, can issue the running time-frequency resource location information, wherein the common signaling can be object by common signaling Manage broadcast channel (Physical Broadcast Channel, referred to as PBCH) or cell specific (Cell specific) Physical Downlink Control Channel (Physical Downlink Shared Channel, referred to as PDSCH).

Preferably, the information of the public resource of distribution includes the running time-frequency resource location information of the public resource of distribution, distribution Public resource entry-into-force time and at least one of period of public resource of distribution.For example, base station can be only by distribution The running time-frequency resource location information of public resource be sent to D2D equipment, D2D equipment at any time can be in the running time-frequency resource position Confidence ceases corresponding position detection and/or monitors the information of other D2D equipment transmission；It base station can also be by the public resource of distribution Running time-frequency resource location information and entry-into-force time of public resource of distribution be sent to D2D equipment, D2D equipment is in the entry-into-force time The corresponding position detection of running time-frequency resource location information and/or monitor other D2D equipment transmission information；Base station can also incite somebody to action The period of running time-frequency resource location information and the public resource of distribution is sent to D2D equipment, and D2D equipment is according to the running time-frequency resource position The period of information and the public resource of distribution knows the running time-frequency resource in period, and detects and/or supervise on the running time-frequency resource in period The information for listening other D2D equipment to send；If it is distribution resource is initially started, which can specify that a resource comes into effect Time, the time of time gap D2D equipment application access needs to meet recipient and can hear a broadcast message, example Such as, which can be 320ms.By the embodiment, base station can notify the relevant information of D2D equipment public resource, so as to D2D equipment can more accurately use the public resource.
