Description
Technical field
The present invention relates to the group technology of wireless communication system terminal enhanced random access signature sequence, relate in particular at 3G (3
RdGeneration) method of stochastic signature sequence grouping during fast access into network under E-FACH (enhancement mode CELL_FACH) state in the system.
Background technology
TD-SCDMA (TD SDMA, Time Division-Synchronous CodeDivision Multiple Access) is one of 3G (Third Generation) Moblie standard.
The most valuable in the mobile communication system is exactly limited frequency spectrum resources, because TD-SCDMA supports the asymmetric business of up-downgoing speed to make that the availability of frequency spectrum can be very high.TD-SCDMA system synthesis has been utilized code division multiple access (CDMA), time division multiple access (TDMA) and frequency division multiple access (FDMA), simultaneously integrated intelligent antenna technology, between the baton handover technology between direct-cut operation and the soft handover and can use the feasibility of multiuser detection to make this 3G scheme have many remarkable advantages in the portable terminal receiver.
The TD-SCDMA system can identical networking or inter-frequency networking, and during inter-frequency networking, the multiple access of a plurality of minizones mainly relies on frequency division multiple access to realize; When adopting identical networking, the multiple access of minizone relies on spreading code-Walsh sign indicating number and cell scrambling to finish jointly.
During identical networking, near the common boundary of a plurality of sub-districts (such as 2 or 3 sub-districts), portable terminal can receive many interference from this sub-district and other sub-district, and the interference of this sub-district can fully utilize when the joint-detection of receiver, can not bring too much influence to receptivity; And from other sub-district (mainly being adjacent sub-district) if interference do not offset or the performance of joint-detection receiver will have very big loss even failure so that power system capacity and handover success rate can reduce largely.
Finish whole service and call out, signaling is set up process and is generally comprised following key step in the TD-SCDMA system, for calling terminal, comprises as shown in Figure 1:
RRC (wireless connection control, Radio Connection Control) connects the process of setting up;
NAS (Non-Access Stratum) signaling connects to be set up and the NAS signalling interactive process;
RAB (RAB) sets up process;
The transmission of traffic signaling.
The signaling procedure and the caller of called end call setup are similar, but many pagings.
The physical accidental access procedure can carry out simply as follows
1. terminal (UE) side
(1) retransmission counter of signature (for inserting 8 SYNC-UL sign indicating numbers distributing to UpPTS at random) is set.
(2) the signature transmitting power being set is Signature_Initial_Power.
(3) in available UpPCH subchannel and signature sequence, select a pair of at random according to given access service grade (ASC, Access Service Classe).Used random function must satisfy each and select selected probability identical.
(4) with selected UpPCH subchannel, with stochastic signature of signature transmitting power emission.
(5) listen to relevant FPACH behind the emission signature, from subsequently WT (network is to a maximum that sends the number of subframes that signature confirmed) subframe, obtain network validation.UE will read the FPACH relevant with launching UpPCH from the subframe that satisfies following relationship
i: (SFN ' mod L
i)=n
RACHin
RACHi=0 ..., N
RACHi-1, FPACH wherein
iFor channel number is the FPACH of i, L
iBe the length of RACH transmission block, n
RACHiBe some PRACH channel numbers of i FPACH correspondence, N
RACHiThe PRACH sum of representing i FPACH correspondence.
(6) if do not detect effective response within the scheduled time, the signature retransmission counter subtracts 1.If counter, then turned back to for the 3rd step still greater than 0; Otherwise report once access failure at random to media access control sublayer.
(7) if detect effective response within the scheduled time, then:
1. according to FPACH
iThe indication that network receives is provided with time and power level value.
2. after the subframe of carrying Signature Confirmation, two subframes of being separated by send RACH message on relevant PRACH.If L
iGreater than 1, and the subframe numbers of confirming is odd number, and UE need wait for a subframe again.If following equation is set up, relevant PRACH is exactly and FPACH
iRelated n
RACHiIndividual PRACH:
(SFN ' mod L
i)=n
RACHi, SFN ' is a subframe numbers of confirming arrival here.
Transmitted power level on UpPCH and the PRACH all can not surpass the numerical value of network by the signaling indication.
2. network side
Base station (Node B) is the emission FPACH relevant with UpPCH in satisfying the frame of following relationship only
i: (SFN ' mod L
i)=n
RACHin
RACHi=0 ..., N
RACHi-1.
Node B can not confirm the UpPCH of the preceding emission of WT subframe.
After one effectively signature receives,, and on relevant FPACH, send the detected signature of FPACH burst affirmation from UpPCH the measurements time deviation of reference time Tref in first footpath of receiving that connects.
If insert at random successfully, terminal goes up transmission RRC at PRACH (Physical Random Access Channel) and sets up request message, and application is set up RRC and connected.
Also there is the E-RUCCH process in TD-SCDMA system for supporting HSUPA, and it mainly finishes the access procedure of HSUPA.It is not the PRACH channel that the access procedure of E-RUCCH and above-mentioned conventional access procedure basically identical, this process that different is are used to send the channel that RRC sets up request message, but the E-RUCCH channel.In order to distinguish this two kinds of access procedures, prior protocols is represented them with different signature sequences.With the sub-district can with 8 SYNC_UL sign indicating numbers be divided into two groups, one group is used for representing that RACH message inserts, another group expression E-RUCCH message inserts, and they are broadcasted in system message.
There is class Always Online (always online) business in the business in various TD-SCDMA system, this class business features is the business of small data packets frequent transmission between terminal and the network, for example PoC (touch-call, Push over Celluar), Push Email (e-mail push) and monthly payment user's demand, their common feature is quite long quiet period is arranged but to require to wake up fast when having data to pass.To some business especially PoC, the connection setup time that customer requirements is shorter.Terminal generally is maintained at CELL_PCH (cell paging, Paging CHannel) state and connects to avoid frequent RRC.When upstream and downstream user face data arrive, network CELL_DCH (cell private channel, the Dedicated CHannel) state of generally these users being moved into has so just had the demand that CELL_FACH status signaling bit rate is strengthened, to improve the call re-establishment time delay, improve user experience.The target that CELL_FACH is strengthened is: the peak rate that improves the CELL_FACH state; Reduce CELL_FACH, user's face under the CELL_PCH state and chain of command time delay; Reduction is from CELL_FACH, and CELL_PCH is to the conversion time delay of CELL_DCH state; By using the power consumption that DRX reduces CELL_FACH state UE.
In order to guarantee the service quality of Always Online business, the TD-SCDMA system should be able to support to insert apace this business.Promptly under the CELL_FACH state, the descending FACH/S-CCPCH that do not re-use, and the relevant channel that uses high-speed packet to insert.
In the TD-SCDMA system, introduced the special uplink channel (E-DCH) of an enhancing, this channel can be regarded as the DCH that has used HARQ (fast physical layer retransmission) and fast dispatch.E-AGCH (absolute allocated channel) is used to be carried as the resource information of up E-DCH channel allocation.In the TD-SCDMA system, E-AGCH has carried the information of 23 or 26 bits, and these information comprise: absolute (power) apportioning cost, code resource information, time interval resource information, E-AGCH cyclic sequence number, the indication of resource continuous time, E-HICH indication and the indication of E-UCCH quantity.Because E-AGCH is a descending shared channel, in order to indicate that the information on this channel is the terminal object that transmits, thus need be with user ID (UE-ID) mask on check code of terminal, judge that by mobile phone whether configuration on the E-AGCH is at oneself.UE-ID is by RRC signaled terminal equipment.
Fig. 2 shows a kind of access realization flow of E-FACH (enhanced FACH), and is as follows:
1. user terminal (UE) is selected one in mode at random in the signature that allows, last signalling, request network insertion.
2. system is after receiving the signature signal that terminal on the UpPTS sends, and signature responded on through the FPACH channel of expansion and distributes the E-DCH resource.
3., then on the E-DCH that has distributed resource, send out the RRC connection and set up request message if user terminal receives the affirmation of FPACH.
4. user terminal is set up message at the RRC that the FACH channel receives network.
When UE request E-FACH inserted, network need be notified the resource allocation conditions of terminal E-DCH, can realize the resource distribution to the E-DCH channel by the expansion to FPACH.Such as transmitting the resource distribution label on FPACH, the resource distribution of each label correspondence is broadcasted in BCH.The FPACH information of carrying comprises like this:
{
(1) signature reference number (the signature number that target mobile phones is launched on UpPTS)
(2) relative subframe number (differential mode 4 of the subframe numbers when subframe numbers when target mobile phones is received FPACH and transmission SYNC_UL)
(3) launch time ((UpPTS of its emission beginning relatively) time migration of target mobile phones emission E-DCH)
(4) E-DCH resource distribution label
}
From above-mentioned access process as can be known, strengthen the transmission rate that the FACH state adopts the E-DCH channel to shorten the time of access at random and improves data (or signaling).For realize strengthening FACH and with the existing system compatibility, need when UE inserts at random, have feasible method to make network can know whether UE needs to strengthen fast FACH and insert.Network just can be given the corresponding acknowledge message of UE (to general access procedure, the original access procedure of network using need not distribute the E-DCH resource to UE on FPACH) according to the access style that UE selects like this, makes UE can finish corresponding access procedure.
