Embodiment

Embodiment one：

As shown in figure 1, the present embodiment provides a kind of Stochastic accessing collocation method, including：

Step S110：Divide user equipment (UE) group；At least include two UE in each UE group；

Step S120：It is that UE components each described match somebody with somebody a random access sequence；

Step S130：The priority of Stochastic accessing is set for the UE in each UE group；

Step S140：Default certain threshold is set, wherein, the default certain threshold is used for when base station is received To the random access request for carrying the random access sequence when, it is determined whether notify UE according to described Priority request Stochastic accessing.

The Stochastic accessing collocation method that the present embodiment is provided, can be to match somebody with somebody applied to the random access resource in base station Put method；Can also be applied to the method in the network side equipment such as mobile management entity or radio management controller.

At least two UE are divided into a UE group in the present embodiment, and match somebody with somebody one for each UE component All UE in the individual random access sequence being used in conjunction with, the UE groups are entered using the random access sequence Row Stochastic accessing.

Also priority can be provided with for each UE of same UE groups in the present embodiment, this is preferential Level is used for when there is multiple UE to need to ask access simultaneously, and priority is used to utilize the random of the group to UE Access the priority that sequence carries out Stochastic accessing.Generally priority is higher in the present embodiment, then has multiple When UE conflicts, then have and the right of Stochastic accessing is preferentially carried out using the random access sequence of the group.

Base station is also by the default certain threshold of setting in the present embodiment, and it is current that the thresholding can be used for base station detection Whether two or more UEs are had while asking Stochastic accessing.The power consumption that usual terminal can be provided is Limited, the signal intensity that terminal is sent every time is also limited, if the reception signal that current base station is received Intensity is very strong, the signal intensity that more than one terminal is sent, then it represents that currently have multiple UE to ask simultaneously Access, occurs in that the conflict of random access request.In order to detect this conflict, it is provided with the present embodiment Default certain threshold.

It is grouped in the present embodiment by UE, just defines the UE that a random access sequence is used simultaneously Quantity, can be prevented effectively from excessive UE in the prior art and be led using the request access of same random access sequence What is caused is overcrowding, and is also provided with priority in the present embodiment, and when a collision occurs, UE can be notified To asking access again according to priority, although and then can reduce it is the same in the prior art keep out of the way, move back The phenomenon conflicted again after circumventing, it is clear that can effectively reduce conflict phenomenon, at the same can also reduce because The limited of random access sequence number causes to allow the limitation of the UE quantity of access.

As further improvement of this embodiment, the step S110 includes：

The division of UE packets is carried out according to UE type of service in the present embodiment, it may include：Will be same The UE of type of service is divided into a UE group, for example, the multiple detection terminals disposed in deep woods.This A little detection terminals can be used for the fire protection information of detection forest or carry out fire prevention early warning etc..This when of multiple detections The type of service of terminal is exactly identical, if these UE are the same areas positioned at forest, now, if Many UE in the UE groups detect the alarm on fire that forest is on fire, has completed on fire by Stochastic accessing Transmission, network side just have received alarm on fire.This multiple UE can be divided into a UE group, utilize one Individual random access sequence carries out Stochastic accessing, as long as UE data transfer success, then network side is just obtained Corresponding information was obtained, using the Stochastic accessing collocation method of the present embodiment, was carried out relative to each UE The prior art of Stochastic accessing, can stand fast at because random access collision causes alarm propagation delay time on fire big Problem.

Certainly when implementing, the division that UE packets are carried out according to UE type of service also may be used Including：The UE of different service types is divided into a UE group as far as possible.Due to different types of industry Business, pair when Ductility Requirement it is different, so facilitate the less demanding UE of delay requirement inevitable, for example, To when the less demanding type of service of ductility UE priority set slightly lower, so convenient realization The differentiation of priority, on the one hand reduces conflict, is on the other hand able to ensure that in Each point in time all as far as possible There is UE to carry out Stochastic accessing using the random access sequence of the UE groups as far as possible, improve random access sequence Effective rate of utilization.Certainly the UE of different service types is divided into a UE group, does not represent one The type of service without two UE is identical in UE groups.Only it is to make the industry in a UE group as far as possible There is differentiation in service type.It is worth noting that, a UE likely corresponds to different types of service. For example, UE A type of service includes business A and business B, the UE A are possible in the present embodiment can To be divided into two UE groups, UE A business A is divided into UE groups A for example, dividing, will UE A business B is divided into UE groups B.Like this, there is Stochastic accessing to UE A business A During demand, Stochastic accessing will be asked using UE groups A random access sequence.

Here according to geographical position carry out UE packets, can include：It will be distributed according to the geographical position Be divided into UE packet in the UE of same packet zone, such base station can by spatial reuse, One random access sequence is distributed into the UE packets positioned at different grouping region, it is maximized to realize at random Access effective utilization of sequence.Certainly during concrete implementation, base station can also be each UE component With a group Radio Resource Network Temporary Identifier, to distinguish each packet.When carrying out random access request, UE can carry the random access sequence and group Radio Resource Network Temporary Identifier of the group simultaneously.Certainly specific When realizing, base station can according to the sense for carrying random access sequence of reception, it is determined which The random access request that individual UE groups are sent, can also space division multiplexing realize the multiplexing of random access sequence.

More than, only it is to provide two kinds of citings that UE packets how are carried out according to type of service and geographical position, Aforesaid way is not limited to when implementing, for example, it is also possible to carry out UE with reference to type of service and geographical position Packet, so as to both be located at positioned at the UE of a UE group in a packet zone, while also real as far as possible The differentiation of existing type of service.For another example, it can be grouped according to UE signing information, signing letter Breath can characterize the communication of UE operations for the signing between UE communication identifier and common carrier The information of the grade of mark, therefore UE packets can also be carried out according to signing information in the present embodiment.Example Such as, the different UE of grade is assigned in a UE group as far as possible, so as in step s 130 as far as possible Realize that the differentiation of priority is set, while reducing conflict, lift effective utilization of random access sequence.

Further, the step S130 may include：

Significantly different business has different time delay tolerance characteristics, and general time delay tolerates the higher business of characteristic, Corresponding priority can be lower.The signing information can be used for the grade for characterizing the UE, and higher grade, Then may be higher to QoS requirement, this when, it may be necessary to which higher priority is set, in this reality Apply in example can by characteristic and signing information can be tolerated according to time delay at least one is preferential to determine Level.

Certainly during concrete implementation, after base station completes step S110 to step S140 setting, The information such as the result, random access sequence and the priority that are grouped UE are needed, UE is sent to and facilitates UE true Know that it is in information such as which UE groups at present.The base station can be using modes such as broadcast, multicast or unicasts Above- mentioned information is sent, preferentially by the way of broadcast or multicast, to reduce the number of times that base station sends above- mentioned information With the shared communication resource.In the present embodiment, Physical Downlink Control Channel (Physical is utilized Downlink Control Channel, PDCCH) or wireless heterogeneous networks (Radio Resource Control, RRC) information sends grouping information, priority and the random access sequence of UE groups.

The Stochastic accessing collocation method provided in the present embodiment can be a kind of semi-static collocation method, also may be used To be a kind of Dynamic Configuration.For example, some M2M terminals are fixedly installed, once its ground is set Reason position is seldom subjected to displacement, and some terminals are mobile.In the present embodiment, can be using dynamic Collocation method, for example, periodically carry out redistributing for UE packets.

In a word, the Stochastic accessing collocation method that the present embodiment is provided, by above-mentioned configuration, can reduce random The collision rate of access, reduces access capacity caused by random access sequence, while more effective profit can be realized Use random access sequence.

In addition, during concrete implementation, methods described also includes：According to the UE of each UE group Quantity, distributes predetermined resource, and the predetermined resource can be used for each UE when there is Stochastic accessing demand, and sending needs Mark is sought, to facilitate base station statistics within the very first time while sending the UE information of Stochastic accessing demand；Enter One step is convenient, and UE is according to oneself priority and has the UE information for sending random access request in the very first time, Determine the Stochastic accessing order of oneself.

Embodiment two：

As shown in Fig. 2 the present embodiment provides a kind of accidental access method, including：

Step S210：Base station receives the first information for carrying the first random access sequence that UE is sent；

Step S220：Base station judges whether the received signal strength of the first information is more than default particular door Limit；

Step S230：When the received signal strength is more than the default certain threshold, then base station is to UE Send the second information；Wherein, second information is used for the first UE groups for notifying to send the first information Interior UE according to priority asks Stochastic accessing.

Accidental access method described in the present embodiment is applied to the accidental access method in base station.In step The first information is received in S210, the first information here can be the Msg1 for carrying random access request.This In Msg1 information format or information resources etc. may refer to prior art, be just not described in detail herein.

Base station is received after the first information, and each random access sequence can be determined by information decoding Signal received signal strength, if the received signal strength of the first random sequence is more than default certain threshold, base station It is believed that current have two UE or more than two UE while asking Stochastic accessing simultaneously, in order to solve to work as Preceding conflict, base station can utilize the second information described in broadcast transmission by step S230, can also multicast transmission institute The second information is stated, can also unicast transmission second information.In a word, sent in the step S230 Two information at least need to ensure have sent to carry the UE that first random sequence sends the first information Second information can be received, thus realize notify the first UE groups need according to priority send with Machine access request.Second information can be Msg2a in the present embodiment.Spy is carried in the Msg2a Different field, when the UE of the first UE groups is received and has decoded second information, is extracted the special field Afterwards, it is believed that currently or currently specifying has two or more UE while utilizing the first random access sequence in the time Request access is, it is necessary to carry out follow-up Stochastic accessing according to priority.Described first is random in the present embodiment Access sequence can distribute to UE any one random access sequence for base station.

After second information is received, UE higher by priority is avoided the relatively low UE of priority, The higher UE of priority is set preferentially to carry out ensuing Stochastic accessing using first random access sequence, So as to avoid the conflict of Stochastic accessing.

The high UE of priority will send the 3rd information after the second information is received to base station, and request is random Access, sets up RRC connections.The 3rd information can be to include RRC connections during concrete implementation Request message, or buffer status reporting (Buffer Status Report, BSR) and/or upstream data. The 3rd information can be sent out using the Msg3a similar with Msg3 of the prior art in the present embodiment Send.

Methods described also includes：

Base station receives the 3rd information that the UE in the first UE groups is sent based on second information；

Base station is based on the 3rd information and sends the 4th information, wherein, at least carried in the 4th information One ascending resource information；The ascending resource information sends the described 3rd to distribute to remove in the first UE groups Other UE beyond the UE of information carry out the resource information of uplink.Base station is in hair in the present embodiment When sending four information, it may be possible to broadcast transmission, then now the 4th information is sent to all in the base station UE in coverage；It is also possible to be that multicast is sent, when multicast is sent, it may be possible to be sent to the first UE groups Interior all UE, it is also possible to be only sent to send the UE of the first information, it is also possible to which unicast is sent out Send, be only sent to the UE for needing to receive the 4th information.It is preferably broadcast transmission or group in the present embodiment Broadcast and send.

Base station will receive the 3rd information that UE is sent after second information is received in the present embodiment, And after the 3rd information is received, send the 4th information.Here the 4th information supplies it including at least one His UE is transmitted the ascending resource information of the ascending resource of upstream data.For example, current UE B is being received After second information, Stochastic accessing is had been completed by the transmission of the 3rd information, by the up of oneself Data or BSR have been sent to base station, like this, base station can be notified by the 4th information other UE by According to priority, the hair of Stochastic accessing and upstream data is carried out using the ascending resource information carried in the 4th information Send.During concrete implementation, the 4th information can also carry the up money of 2 or more than 2 Source information, the ascending resource information corresponds to a uplink transmission resource, then the UE of a UE group According to respective priority and the time sequencing of each uplink transmission resource, it is determined that each up using which Transfer resource sends data.The higher UE of usual priority, is sent out using time more forwardly of uplink transmission resource Upstream data is sent, to complete Stochastic accessing.

In the present embodiment, also carried on first received from the 3rd information in the 4th information Row data, for informing that UE base stations have been properly received first upstream data, to avoid redundancy from sending.

Base station carries the first upstream data received from the 3rd information in the 4th information, and so preparation is sent The UE of information, will extract first upstream data from the 4th information, if there is UE to find the line number on first According to, it is exactly the data for oneself needing to send to base station, and base station has received that, then the UE can stop The first upstream data is sent, the redundancy reception with base station is sent with the redundancy for avoiding UE, and can avoid superfluous The remaining communication resource for sending occupancy, and redundancy reception take the system resource of base station.

Methods described also includes：

If base station is unsuccessfully received the 3rd information, base station is pre- for the UE for sending the 3rd information Stay retransmission resource.

For example, base station here is unsuccessfully received the 3rd information, including do not distributing to UE's Information, or the information BER excess received are received on ascending resource, causes reception failure, then is hair Send the UE of the 3rd information to reserve retransmission resource, facilitate the re-transmission of the information content in the 3rd information.

During implementing, re-transmission is divided into adaptive retransmission and non-self-adapting is retransmitted.It is divided to two kinds of feelings below Condition, is received respectively, and base station is for different disposal under two kinds of different retransmission mechanism.

Methods described also includes：

When UE retransmission mechanism is adaptive retransmission, then base station sends uplink grant to UE and indicated, To indicate the retransmission resource.

For adaptive retransmission, base station in reserved retransmission resource, it is necessary to re-start up-link (Uplink, UL) authorize Grant to redistribute out an ascending resource, the uplink grant is indicated, be sent to pair The UE answered, to indicate that the UE is retransmitted on the ascending resource.In the present embodiment in order to can utilize UE special mark is scrambled, for example, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI is scrambled, then other UE Receiving the information can not also decode, so that the reserved retransmission resource will not be taken.

Methods described also includes：

When UE retransmission mechanism retransmits for non-self-adapting, then base station is indicated using physical mixed autonomous retransmission Channel indicates the carrying content of reception failure or the 4th information for passing through transmission to indicate reception failure.

In a word, the UE described in the present embodiment is special with the small grade of random access collision when carrying out Stochastic accessing Point.

Below in conjunction with above-described embodiment, there is provided several specific examples：

Example one：

Base station is grouped for UE, and individually organizes Radio Network Temporary Identifier Group for every group of UE configuration Radio Network Temporary Identity G-RNTI and random access sequence, for each UE in the group Configuration sends the priority of upstream data.The division of UE groups can consider simultaneously the geographical position residing for UE with And UE type of service.One UE may support multiple business, therefore same UE may belong to simultaneously Multiple packets.When needing to initiate from the Stochastic accessing of some type of service, this group of UE can only be used with being somebody's turn to do The corresponding random access sequence of business initiates Stochastic accessing.UE priority configuration can based on UE when Prolong tolerance characteristic, signing situation.UE sends priority and can indicated by PDCCH, can also pass through RRC is indicated.When needing to initiate the Stochastic accessing of some business, this group of UE need with the business Corresponding random access sequence initiates Stochastic accessing.

The reception signal that base station detects same random access sequence within same moment or a period of time is strong Degree exceedes default certain threshold, just by accidental access response protocol Data Unit RAR PDU (Random Access Response Protocol Data Unit) Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Temporary Cell-RNTI) domain is set to special field, to inform this group of UE, is sent according to the UE being pre-configured with Priority orders send signaling or data successively.

The certain threshold is preconfigured values.

The Cell Radio Network Temporary Identifier/Identity, Cell-RNTI domain is set to special field, Ke Yishi, by cell-radio network Temporary mark domain is set to full 0 or 1, or is set to random access radio network temporary mark (Random Access Radio Network Temporary Identifier, RA RNTI) etc..

A kind of schematic diagram for RAR PDU that Fig. 7 provides for the present embodiment.

Here the received signal strength detected in a period of time refers to：Signal intensity is engraved when multiple Superposition.For example in a 10ms radio frames the 1st, 3, all detect identical Stochastic accessing sequence in 5 subframes Row, and the signal intensity of the random access sequence is respectively a, b, c in these three subframes, then 10ms The random access sequence signal intensity that interior (in a period of time) detects is a+b+c.

According to the transmission priority orders being pre-configured with, this group of UE is sent on the ascending resource of distribution successively Msg3a.Here the 3rd information that Msg3a may correspond in previous embodiment.Msg3a can be RRC Connection set up request message, or buffer status reporting (BSR, Buffer Status Report) and/ Or upstream data.

G-RNTI must be carried in Msg3a by sending the UE of highest priority.Base station is receiving this After G-RNTI, this can be determined according to G-RNTI and the corresponding relation of UE quantity in UE groups The UE quantity included in UE groups.

The unique designation of current UE can also be carried in Msg3a：C-RNTI or from the unique of core net UE indicates that (SAE Temporary Mobile Subscriber Identity, SAE are moved such as S-TMSI temporarily Employ family mark) or a random number.

When some UE no data is sent, any data can not be sent.

Base station is received after Msg3a, sends Msg4a.Msg4a is scrambled by G-RNTI.In the present embodiment Described in Msg4a can be equivalent to the 4th information in previous embodiment.Msg4a will at least include next UE up transmission resource.

Priority of the UE based on itself, UE judges whether that taking turns to oneself sends signaling or data.If it is, Receive the Msg4a that base station is sent.Can also be that UE distributes a Temporary Cell Radio Network by Msg4a Temporary mark TC-RNTI/C-RNTI, now current UE need monitor Msg4a.

Example two：

This example combines the content in example one, further comprising the steps of：

Current UE sends upstream data in Msg3a.

The Msg4a that base station is issued will not only include next UE UL Grant, should also include current The copy of data in the data that UE is sent, i.e. Msg3a, to inform that base station has been known with other UE are organized The road message, identical message may not necessarily be sent.The repetition of redundancy message is avoided to send and receive with this, The unnecessary signaling consumption of reduction, reduces terminal implementation complexity.

In enhancing accidental access method implementation procedure, if some UE has found oneself by receiving Msg4a The data for wanting to send have been changed to redundancy message (i.e. other UE signals base), just no longer monitor Msg4a, i.e., directly terminate current random access procedure.If the UE has found the data type for oneself wanting to send The business currently accessed is not belonging to, just Stochastic accessing is initiated again to base station in other resources.

Example three：

This example combines the content in example one and example two, it is considered to which base station is not successfully received the letter of UE transmissions , it is necessary to the problem of retransmitting during breath.

Just it is the reserved weights of the UE when base station finds that current UE sends upstream data not on Msg3a Pass resource.The timing relationship of retransmission time can be consistent with existing protocol.Msg3a maximum retransmissions It can be differently configured from the Msg3 maximum retransmissions maxHARQ-Msg3Tx defined in existing protocol.

Msg3a re-transmission can be with right and wrong adaptive retransmission or adaptive retransmission.

When non-self-adapting is retransmitted：

Base station is that UE reserves retransmission resource, and according to timing relationship, UE can also deduce the position of retransmission resource.

If Msg4a replicates the data in Msg3a, then UE is known that by reading Msg4a simultaneously Whether base station is successfully received the Msg3a of oneself transmission, therefore is indicated without PHICH.If UE does not have The Msg3a data of oneself transmission are read in Msg4a, non-self-adapting is just initiated and retransmits.

If in Msg4a do not include Msg3a data, then base station need to be told by PHICH UE this Whether secondary transmission succeeds.If UE receives PHICH and indicates NACK, just initiate non-self-adapting and retransmit.

When adaptive retransmission：

Base station can distribute a new UL Grant for UE, and the UL Grant are indicated by PDCCH. UL Grant (being scrambled with G-RNTI) different from distributing to next UE, re-transmission UL Grant are used should UE specific identity scrambling, such as C-RNTI.

Example four：

The accidental access method provided with reference to above-mentioned example, the method that this example is provided also includes：

The access demand of the UE meeting signals bases oneself of random access sequence is sent, that is, is desired access to.For example, Using the predetermined resource in previous embodiment, transmission demand mark carrys out the access demand of signals base oneself.

Base station receives meeting after all UE of UE groups access demand, informs which all UE of the UE groups have UE can initiate access process, the UE for thus conveniently having access demand, according to the priority of oneself and other There is the UE of access demand, determine the Stochastic accessing order of oneself this Stochastic accessing.

One kind is possible to be achieved in that：

In Msg2a, base station is that this group of UE distributes one piece of ascending resource, and this group of UE is in the up money of this block Access demand is sent on source.Such as each UE reports the demand of oneself with a PRB, with higher priority UE use compared with low-frequency range resource.As shown in figure 8, UE 1 to UE 13 be one group, UE 1 have compared with Height sends priority, and the priority of UE 13 is minimum.UE 2, UE 4, UE 5, UE 10, UE 13 have access Demand, therefore the access demand of oneself is sent in the resource that base station is distributed, such as on one's own PRB Send complete 1 bit of 1 byte.Other UE do not have access demand, will not also make any response.

Base station can inform which all UE of the group have in step 4 after receiving all UE of group access demand A little UE can send upstream data.Such as by way of bitmap, 1 represents " access ", and 0 represents " not connect Enter ".Therefore, the message that this group of UE is received in step 4 is " 0101100001001 ".

According to conditions of demand " 0101100001001 " of the same group of UE of base station feedback to multi-upstream access, UE roots According to the nearly priority of itself and the priority for other UE for having transmission demand, determine this Stochastic accessing with Machine access order.UE 2, UE 4, UE 5, UE 10, UE 13 transmission priority are followed successively by 1,2,3, 4、5.When receiving first uplink grant instruction, priority is sent for 1 UE 2 using the resource Msg3a；When receiving second uplink grant instruction, priority is sent for 2 UE 4 using the resource Msg3a。

Example five：

Each UE safeguards a priority counter, and each UE is received when uplink grant is indicated and counted Number device subtracts 1, and it is one's own to represent that this uplink grant is indicated when counter is 0, and oneself can To send data on corresponding ascending resource.It can be to be carried on foregoing implementation that the uplink grant, which is indicated, Information in example in the 4th information.

Assuming that UE a, UE b, UE c priority are followed successively by 1,3,2, then these three UE's is preferential Level counter can be respectively 0,2,1.

(received when UE a, UE b, UE c receive first uplink grant instruction in Msg2a Uplink grant indicate), UE a have found that the priority counter of oneself is 0, expression now should oneself Send, upstream data or BSR are just sent on the ascending resource of distribution；And now UE b, UE c are sent out The existing counter of oneself is not 0, just subtracts 1 by the counter of oneself, is changed into 1,0 respectively.

When UE b, UE c receive a uplink grant instruction again (i.e. UL Grant in Msg4a), UE c have found that the priority counter of oneself is 0, represent oneself should now send, just in the up of distribution Upstream data or BSR are sent in resource；Now the counter of oneself is subtracted 1 by UE b, is changed into 0.This table Show if UE b receive a uplink grant and indicate (being also the UL Grant in Msg4a) again, just send out Give the upstream data or BSR of oneself.

Example six：

This example, which provides a kind of accidental access method, to be included：

Base station receives the first information for carrying the transmission of the first random access sequence；

Judge whether the received signal strength of the first information is more than default certain threshold；

If the reception signal receiving strength is more than the default certain threshold, it is determined that currently utilizing described first Random access sequence asks the UE information of Stochastic accessing；Here UE information may include UE quantity；May be used also Priority including UE marks or these UE；

The UE information is sent to UE, and notifies UE to carry out Stochastic accessing according to priority；Specifically may be used UE is notified to carry out Stochastic accessing according to priority by above-mentioned second information.May be used also in second information At least carry the resource information of a uplink transmission resource.

After uplink transmission resources of the UE based on distribution is received, the 4th information is sent；4th information Carry the resource information correspondence carried in the resource information of at least one uplink transmission resource, the 4th information Uplink transmission resource, for other UE carry out Stochastic accessing, complete uplink；The step is repeated, Up to all being obtained using all UE for asking Stochastic accessing using the random access sequence of prime number first in the very first time The uplink transmission resource arrived, completes data transfer.

For example, the UE numbers that the same same random access sequence of time utilization sends the first information are 5； Then base station can repeat the transmission of 4 the 4th information after second information has been sent, so that often The UE for the first information that the same random access sequence of one utilization is sent can send a first information Afterwards, Stochastic accessing is completed.The first information can be random access information in the present embodiment.
