Description
Technical field
The present invention relates to a kind of enhanced FACH access method and system, relate in particular to a kind of enhanced FACH access method and system that utilizes the temporary transient initial user sign mapping of calling out the terminal that inserts.
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, makes 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 baton handover technology between direct-cut operation and the soft handover and the feasibility that can in the portable terminal receiver, use multiuser detection, make this 3G scheme have many remarkable advantages.
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 is to rely on to realize by frequency division multiple access; When adopting identical networking, the dependence of the multiple access of minizone spreading code---finish jointly by Walsh sign indicating number and cell scrambling.
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, cause power system capacity and handover success rate to 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, as shown in Figure 1, comprises following process:
RRC (wireless connection control, Radio Conne ction 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.UE terminal) side
(1) retransmission counter of signature (for inserting 8 SYNC-UL sign indicating numbers distributing to uplink pilot time slot UpPTS at random) is set.
(2) the signature transmitting power being set is Signature_Initial_Power.
(3) from the available UpPCH subchannel of given access service grade (ASC, Access Service Classe), select one arbitrarily.Used random function must satisfy each and select selected probability identical.
(4) with selected UpPCH subchannel, with 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 FPACHi:(SFN ' mod Li relevant with launching UpPCH from the subframe that satisfies following relationship)=nRACHi; NRACHi=0 ..., NRACHi-1, wherein FPACHi is that channel number is the FPACH of i, and Li is the length of RACH transmission block, and nRACHi is some PRACH channel numbers of i FPACH correspondence, and NRACHi represents the PRACH sum of 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 (3) 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. the indication that receives according to the FPACHi network 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 Li is greater 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 nRACHi the PRACH related with FPACHi:
(SFN ' mod L)=nRACHi, SFN ' is a subframe numbers of confirming arrival here, L is the length of user ID UE-ID.
Transmitted power level on UpPCH and the PRACH all can not surpass the numerical value of network by the signaling indication.
2. network side
Node B (base station) is the emission FPACHi:(SFN ' mod L relevant with UpPCH in satisfying the frame of following relationship only)=nRACHi; NRACHi=0 ..., NRACHi-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.
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.
When E-DCH being applied to strengthen the FACH access, whole process was finished before RRC sets up signaling, so according to Current Standard, terminal does not obtain UE-ID (user ID) as yet.Therefore can't transmit and receive the signal on the E-AGCH.
