By adopting the embodiment of the invention, the PRACH resource information of the frequency points at the network side is obtained by the terminal, and the frequency point is selected to access according to the PRACH resource information of the multiple frequency points so that the terminal in the multiple-frequency point system can select the proper frequency point to access, the success ratio of terminal access is improved, the access load of the various frequency points is balanced, and the network operation efficiency is improved.
Description
Technical field
The present invention relates to communication technical field, relate in particular to terminal access method, system and equipment in a kind of multiple frequency point system.
Background technology
HSPA (High Speed Packet Access, high-speed packet inserts) technology is a kind of new technology that 3GPP (3rdGeneration Partnership Project, third generation partner program) introduces.The HSPA technology is simultaneously applicable to WCDMA (Wideband Code Division Multiple Access; WCDMA) FDD (Frequency Division Duplex; FDD), UTRA (UniversalTerrestrial Radio Access; Universal terrestrial radio inserts) TDD (Time Division Duplex, time division duplex) and three kinds of different transmission modes of TD-SCDMA (Time Division-Synchronization CDMA, Time Division-Synchronous Code Division Multiple Access).Usually HSPA is carried on the single frequency point, for the message transmission rate that further improves the HSPA system, reduce data transmission delay, has occurred bundling the system that is used to carry the HSPA data to a plurality of frequencies.In the HSPA system that adopts multifrequency point, the data channel of a plurality of frequencies will be bundled in and be used to transmit the HSPA data together on the down direction, that is: a UE (User Equipment, subscriber equipment) can receive the data of data channel on a plurality of carrier waves simultaneously.Particularly, UE carries out channel estimating according to the pilot tone among the P-CPICH (Primary Common Pilot Channel, Primary Common Pilot Channel), obtains the transfer function of channel, solves the data on a plurality of data channels through inversion then.
ACB (Access Class Barring; The access grade restriction) be UMTS (Universal MobileTelecommunication System; Conventional wireless communication systems) suppresses overload in and prevent a congested important function; It can trigger when high capacity is detected, also can when high capacity is predicted, trigger, thereby can limit the Control Network load to some users.
The relation of AC among the UMTS (Access Class, access grade) and ASC (Access Service Class, access service grade) is as shown in Figure 1.AC is distributed by operator and is kept among the USIM (UMTS Subscriber Identity Module, UMTS Subscriber Identity Module), and wherein AC=10 keeps to urgent call.Restriction state information indication in SIB3 (SystemInformation Block 3, system information block 3) of a 1bit is all arranged for each AC.When the UE demand signalling that is in idle condition connects foundation, UE will carry out the mapping of AC to ASC, and mapping relations are indicated in SIB5.Each AC can be mapped on the ASC, and each ASC can more related PRACH (PhysicalRandom Access Channel, Physical Random Access Channel) resource, and ASC and available PRACH resource mapping are closed to tie up among the SIB5 and indicated.Each ASC can set the load that a lasting grade is used to control RACH, and N (scope is 1 to 8) indicates in SIB7, is used to control lasting grade P (N)=2
-(N-1)For urgent call, lasting grade all is 1 forever, means that each RACH can both send.
In the multi-frequency-point community of prior art, the data channel that only configuration data transmits on each frequency, all common down channels all are disposed on the dominant frequency point.After the UE start, just can only on the dominant frequency point that has disposed common down channel, carry out synchronously and access procedure.
For example, when UE inserts at random, at first on the PRACH on the frequency that has disposed common down channel, use certain transmitting power to send an access lead.After network side receives this access lead,, just go up feeding back ACK (Acknowledge confirms to reply) message at AICH (Acquisition Indicator Channel, AICH Acquisition Indication Channel) if corresponding access-in resource is arranged.After UE receives ACK message, on PRACH, send and insert message and accomplish access.If there is not corresponding access-in resource, network side just feeds back NACK (Negative Acknowledgement, negative response) message on AICH, after UE receives NACK message, can after certain interval of time, initiate access procedure again.If UE does not still receive ACK message after a time; Then the access lead of redispatching under the situation of transmitting power can strengthened; If UE does not still receive any ACK message on AICH, then repeat said process, after reaching maximum retransmission, abandon inserting.
The inventor finds that there is following problem in prior art in realizing process of the present invention:
All common down channels of multiple frequency point system all are disposed on the dominant frequency point in the prior art.Therefore, UE can only carry out access procedure on the frequency that has disposed common down channel, can cause the load of this frequency excessive like this, is unfavorable for bringing into play the characteristic of multiple frequency point system.

Step s604, UE connect the ASC that obtains two frequencies initialized the time in signaling.
Step s605, UE select available PRACH resource according to the mapping relations of PRACH resource and corresponding frequency and the mapping relations of ASC and corresponding frequency.
Below specifically the PRACH resource selection method among the step s605 is described.After UE gets access to PRACH resource available on ASC and two frequencies of two frequencies, can use following rule to select suitable frequency to insert:
UE has got access to the value v2 of ASC of value v1 and auxilliary frequency of the ASC of dominant frequency point, then UE can:
< 1>UE selects less ASC frequency points corresponding to insert according to ASC size corresponding in two frequencies, and such as v1＜v2, UE selects the dominant frequency point to insert so.
< 2>if v1=v2, then UE considers the PRACH resource that ASC separately is corresponding, such as the quantity of resource etc., selects suitable frequency to insert according to system's needs then.
< 3>perhaps < 1>and < 2>both synthetic determinations.
Need to prove that the described choice criteria in above-mentioned < 1 >～< 3>is preferred embodiment of the present invention, and be not used in choice criteria is limited.Is example with above-mentioned ASC size with UE correspondence in two frequencies as choice criteria; Embodiments of the invention are not limited to only select the pairing frequency of less ASC to insert; Also can select other frequencies to insert as required according to other preset standard like the pairing frequency of bigger ASC.
