Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of enhancing accidental access method and device.
Background technology
3-G (Generation Three mobile communication system) Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time-DivisionSynchronization Code Division-Multiple-Access) in the system, mobile terminal device (UE, User Equipment) process of connecting system and second generation gsm system are similar, but because system has increased the processing to uplink synchronous specially to the specific (special) requirements of net synchronization capability in the random access procedure.
In a subframe, there is the uplink and downlink time slot in TD-SCDMA radio frames subframe structure simultaneously, amounts to 7.Must be used for the up direction except that time slot Ts0 must be used for descending, time slot Ts1, the direction of all the other time slots can change.The corresponding descending respectively and uplink synchronous time slot of DwPTS (downlink pilot time slot) and UpPTS (uplink pilottime slot), GP are guard time interval between up-downgoing.
After the UE start, at first must set up down-going synchronous with the sub-district, could begin to set up uplink synchronous then.When UE inserts at random, though can receive the DwPTS signal of base station, set up down-going synchronous, and do not know and the base station between distance, this causes the up first transmission of UE can not arrive the base station synchronously.Therefore, in order to reduce the interference to conventional time slot, being sent in first on this special time slot of UpPTS of up channel carried out.Consider the complexity of wireless channel, utilize power to estimate that propagation delay time is very inaccurate, can allow UE send uplink synchronous code (SYNC_UL, synchronous uplink) with a fixing transmitting time lead.
Then, the SYNC-UL sequence is detected in the base station in search window, can estimate SYNC-UL received power and due in.The base station sends feedback information by forward physical access channel (FPACH, Forward physicalaccess channel) to UE, provides UE emitted power next time and time adjusted value, so that set up uplink synchronous.
Under the normal condition, the base station is made UE in will 4N subframe after receiving SYNC-UL and being replied.If UE (value of N is by system configuration) in 4N subframe does not receive from the replying of base station, think that then synchronization request sends failure.UE will random delay a period of time, restarts to attempt synchronized transmission.
High speed uplink packet inserts (HSUPA, High Speed Uplink Packet Access) be the technology of being developed for transmitting high speed upstream data in the 3G (Third Generation) Moblie, can be used to the desired multimedia of international mobile communication standards in 2000 (IMT2000, International Mobile Telecommunications 2000), video flowing and other IP operation that provide complete.
Subscriber equipment (UE, User Equipment) can adopt the HSUPA enhancement techniques when system sends data.As shown in Figure 1, because whether UE can send data by system's control to system, its access procedure is specially:
When UE need be when system sends the HSUPA upstream data, UE sends random access control channel (E-RUCCH, the E-DCH Random access Uplink Control Channel) message that strengthens to system;
Because E-RUCCH and Physical Random Access Channel (PRACH, physical random accesschannel) takies identical physical resource, therefore system must could determine that UE is E-RUCCH message or PRACH message by message transmitted on the physical channel through after E-RUCCH and two kinds of decoding processing of PRACH.
When system carries out E-RUCCH decoding and PRACH decoding, can adopt parallel mode or serial mode to handle.As shown in Figure 2, system parallel carries out E-RUCCH and PRACH decoding is handled after receiving data on the shared physical channel of PRACH.As shown in Figure 3, system does E-RUCCH decoding earlier to the data that receive and handles on the shared physical channel of PRACH, if decoding failure is done PRACH decoding again and handled.
Correctly receive the E-RUCCH request message of UE when system (as Node B), and when definite UE can send data, will be for UE distribute available physical resource and power, and these control messages are notified to UE, UE begins to send uplink strengthening data to system after receiving control messages.
Yet, adopt above-mentioned realization to strengthen the prior art scheme that inserts at random and be not suitable in the TD-SCDMA system, directly using.TD-SCDMA is the system of a strict synchronism, if long-time useless being called of UE just may lose uplink synchronous, can not guarantee correctly to be received by NodeB so directly send E-RUCCH message, also may bring interference to other time slot data.In addition, the collision probability of the E-RUCCH of different UEs or PRACH is also bigger.

Embodiment
Be that example further describes the present invention with the TD-SCDMA system below.In the system that adopts HSUPA, it is at random that UE sends the request of access to system, that is to say that Node B does not know when UE has data and send.In addition, the request of access at random that UE sends to system might be the common request that inserts at random, also may be to strengthen the request that inserts at random.For this reason, the present invention proposes new solution, and when terminal send to strengthen when inserting request at random to system, system can adopt and be similar to the common process that inserts at random and handle accordingly, thereby avoids bumping.
Below, in conjunction with Fig. 4 and Fig. 5, elaborate terminal and insert the processing of request process at random to system's transmission enhancing, specific as follows:
Step 501:UE sends the ascending pilot frequency sign indicating number to Node B;
Step 502:Node B detects and receives the ascending pilot frequency sign indicating number that UE sends;
Step 503:Node B sends FPACH message to UE;
After step 504:UE receives this FPACH message, send the enhancing data to Node B and insert request E-RUCCH;
Step 505:Node B carries out decoding processing to E-RUCCH after receiving the E-RUCCH of UE transmission, to judge whether that allowing UE to send strengthens data;
Step 506: if decode successfully, allow UE to send and strengthen data, then send configuration messages such as physical resource, power to UE; Otherwise finish.
After step 507:UE receives configuration messages, send the enhancing data, finish then to system.
Because it is commonly to insert at random and strengthen the combination that inserts two processes at random existing that the present invention strengthens random access procedure, therefore, will the concrete processing procedure in each step be explained detailedly below.
The first step of travelling carriage connecting system is the synchronous of acquisition and current area.This process is to realize by the SYNC_DL that catches cell downlink synchronization slot DwPTS.SYNC_DL is 64 predetermined PN sequences of a system, and SYNC_DL has 32 kinds of possible selections at most.The SYNC_DL of neighbor cell is different in the system, and the SYNC_DL of non-conterminous sub-district can be multiplexing.SYNC_DL is included in the DwPTS time slot in the TD_SCDMA wireless burst.
According to the wireless frame structure of TD-SCDMA, SYNC_DL every 5ms in system sends once, and all sends this information with constant full power value at every turn.During the travelling carriage connecting system, 32 SYNC_DL code words are searched for one by one.
Here need to prove that because there is strict demand in the TD-SCDMA system to upstream synchronous timing, so the data of different user will be benchmark with the time of base station all, arrive Node-B in the predetermined moment.The time precision of stepping adjustment is 1/8chip, and time corresponding is 0.097 μ s, and adjust maximum variable quantity is 1chip at every turn.Corresponding, the aerial bit rate of GSM is 270.833kbit/s, and it is 1bit that the time is adjusted precision, and corresponding time precision is 3.69 μ s.
After UE on the down link and system obtained synchronously, because the distance relation of UE and Node B, system can't correctly accept the message that UE sends.For fear of sending message and system is caused interference in inappropriate time, UE at first will send SYNC_UL at up direction on the UpPTS time slot.The UpPTS time slot is exclusively used in the uplink synchronous of UE and system, does not have user's business datum.
According to system's setting, corresponding 8 the SYNC_UL code words of each DwPTS sequence number, UE determines the upstream SYNC _ UL code word that will use at random according to the DwPTS information of receiving.Similar with the mode of UE decision SYNC_DL, Node B can adopt the way that carries out related calculation one by one, and which uplink synchronous code word what judge the current use of UE is.
The SYNC_UL that UE sends receives in system, just can obtain timing and the power information of SYNC_UL.And determining transmitted power and the time modulation value that UE should use thus, a certain subframe in ensuing 4 subframes sends to UE by the FPACH channel.In the FPACH channel, also comprise the SYNC-UL codeword information of UE primary election and the relative time that Node B receives SYNC_UL, distinguishing the UE that uses different SYNC-UL in the section at one time, and the UE that uses identical SYNC-UL in the different time sections.UE just can learn whether the uplink synchronization request of oneself is accepted by system after receiving these information Control orders on the FPACH.
UE is after receiving FPACH message, send the data that strengthen to Node B and insert request, owing to adopt with common and insert identical SYNC_UL sign indicating number at random, and E-RUCCH can take identical physical resource with PRACH, and the mapping relations of SYNC_UL sign indicating number and FPACH and E-RUCCH are handled respectively.Because E-RUCCH takies identical physical resource with PRACH, so system must could determine that UE is E-RUCCH message or PRACH message by message transmitted on the physical channel through after E-RUCCH and two kinds of decoding processing of PRACH.When system carries out E-RUCCH decoding and PRACH decoding, still can adopt the parallel series mode processing procedure shown in Fig. 2 and 3, repeat no more herein.E-RUCCH message adopts different check codes with PRACH message, and the check code of E-RUCCH message can be the upset of PRACH message check code.Here said upset, for by 0,1 bit sequence of forming, upset is meant and becomes 1 with 0, becomes 0 with 1; For the then is-symbol negate of signed numerical value.
Node B if determine that UE need carry out enhancement mode and insert at random, then sends configuration messages such as physical resource, power through after the above-mentioned decoding processing to UE, UE begins to send uplink strengthening data to system on channel subsequently.
In the TD-SCDMA system, the specific implementation process that E-RUCCH inserts can be described from MAC layer and physical layer respectively.
One, the MAC layer access procedure of E-RUCCH
As shown in Figure 6, it is specific as follows that E-RUCCH sends the process of controlling:
E-RUCCH sent Control Parameter below step 601, MAC received from Radio Resource control (RRC, Radio Resource Control):
ASC collection parameter comprises each ASC, i=0 ..., NumASC, SYNC-UL are cut apart sign i and persistent value Pi (sending probability).
The maximum cycle Mmax of SYNC_UL;
If step 607 FPACH confirms lock-out pulse, physical layer is to MAC notice access information ACK (affirmation), and then MAC asks the E-RUCCH transfer of data, and physical layer adopts relevant E-RUCCH resource with FPACH to finish the transmission of E-RUCCH message.
If step 608 physical layer is not received the affirmation of FPACH and the maximum cycle of SYNC_UL and is not surpassed permissible value, so, physical layer is notified NAK (denying) information to MAC, and new lasting test will be carried out in next Transmission Time Interval, and repeats the physical layer joining procedure.The lasting test that timer T2 has guaranteed twice success is a Transmission Time Interval at least at interval.
If step 609 surpasses the maximum cycle of SYNC UL, MAC will stop the E-RUCCH access procedure, abandon message.
Two, the physical layer access procedure of E-RUCCH
The set-up procedure that the set-up procedure of E-RUCCH access procedure and TD-SCDMA insert is basic identical.UE can at first keep down-going synchronous and read broadcast, just can carry out the E-RUCCH access procedure then.The SYNC-DL sign indicating number (signature) that uses from DwPTS, UE can obtain to inserting the sign indicating number collection of 8 SYNC-UL sign indicating numbers distributing to UpPTS at random.Some parameters (sign indicating number, spreading factor, intermediate code, time slot) about PRACH, FPACH all can go up broadcasting at broadcast channel (BCH, Broadcast Channel).Therefore, when sending the SYNC-UL sequence, the resource (can set up the corresponding relation of E-RUCCH and FPACH) that FPACH resource and E-RUCCH took when UE knew access.
Before the initialization of E-RUCCH access procedure, physical layer need receive the following message from rrc layer:
1. signature and the related situation of FPACH; The related situation of FPACH and PRACH/E-RUCCH; Listed physical channel parameters.
The length of 2. relevant with FPACHi PRACH/E-RUCCH message can be configured to 1,2 or 4, and corresponding time span is respectively 5ms, 10ms or 20ms.
Here, NRACHi PRACH can be related with FPACHi.The maximum NRACHi that allows equals Li.
3. the available UpPCH subchannel of each access service grade (ACS, Access Service Class).
4. the transmission format parameters of PRACH message set.
5. maximum sends number " M " among the UpPCH.
6. be used to wait for that network is to a maximum " WT " that sends the number of subframes that signature confirmed.
7. the power " Signature-Initial-Power " of initially signing
The concrete access procedure of E-RUCCH is:
Follow protection time slot SYNC_UL sequence afterwards closely and only be used for uplink synchronous in UpPTS, UE selects one at random from 8 possible SYNC UL sign indicating numbers that adopt the sub-district of wanting to insert, and sends it to the base station on the UpPTS physical channel.UE determines launch time and the power (open loop process) of UpPTS then, so that the condition code that emission is selected on the UpPTS physical channel.
In case Node B detects the UpPTS information from UE, time and received power that UE arrives have so also just been known.Node B determines the instruction that transmitting power is upgraded and regularly adjusted, and sends to UE by FRACH (a burst/subframe message) in 4 subframes afterwards.
When UE receives above-mentioned control information from selected FPACH (FPACH corresponding with selected condition code), show that Node B has received the UpPTS sequence.Then, UE will adjust launch time and power, and guarantee behind ensuing two frames, send E-RUCCH message on corresponding to the E-RUCCH channel of FPACH.In this step, the E-RUCCH that UE sends to Node B will have the higher synchronous precision.Because the power level value of FPACH feedback is at the PRACH channel, so the transmitting power of E-RUCCH should increase a power offset delta P.Δ P is relevant with the PRACH encoding variability with E-RUCCH.
Afterwards, UE will monitor the access grant channel (E-AGCH, AccessGranted Channel) of the enhancing of distributing to UE, and judges whether UE can send up access data.
In addition, message content and the encoding process process to the E-RUCCH carrying is respectively described below:
1, the signaling of the E-RUCCH of TD-SCDMA system carrying comprises following content:
Serving cell and adjacent sub-district path loss information (SNPL, Serving and Neighbour Cell Pathloss), 5 bits are mapped as a metric;
The relative maximum transmission power that UE can use (UPH, UE Power Headroom), 5 bits;
Highest priority data accounts for the ratio (HLBS, Highest priority Logical channelBuffer Status) of total buffer memory, and 4 bits are mapped as different percentage values;
Total E-DCH buffer status (TEBS, Total E-DCH Buffer Status), 5 bits are mapped as different cache size grades;
Highest priority logical channel ID (HLID, Highest priority Logical channel ID), 4 bits, different I D characterizes different priorities;
The HSUPA ID of UE number (H-RNTI, E-DCH Radio Network TemporaryIdentifier), 16 bits.
2, encoding process process
CRC check code length is 16;
Convolutional encoding;
Rate-matched;
Bit add around;
Intra-frame interleaving;
The physical channel mapping.
At last, as shown in Figure 7, for strengthening the accidental access device block diagram.This device comprises: receive processing unit 71, message sending unit 72 and codec processing unit 73.
It is as follows to strengthen the processing procedure that inserts at random by this device:
Receive the ascending pilot frequency sign indicating number sequence that processing unit 71 detects and receiving terminal sends, send feedback message by the forward physical access channel to terminal by message sending unit 72 then; Receive the enhancing data access request that processing unit 71 receiving terminals send, commentaries on classics inserts request by 73 pairs of these enhancing data of codec processing unit and carries out decoding processing, judge whether to allow terminal to send then and strengthen data, strengthen data if determine to allow this terminal to send, then send configuration messages such as physical resource, power to this terminal by message sending unit 72; Received by the enhancing data that receive 71 pairs of terminals transmissions of processing unit again.
