Description

Terminal scheduling method, system and equipment
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of terminal scheduling method, system and equipment.
Background technology
For TD SDMA (TD-SCDMA) system, in the 8th version (3GPP Release8) of 3G (Third Generation) Moblie standard, introduced cell forward access channel (CELL_FACH) and strengthened characteristic.Strengthen in the characteristic at CELL_FACH, with high speed downlink packet access (High speed DownlinkPacket Access, HSDPA) and correlated channels and the transmission mechanism of high speed uplink packet access (High speed Uplink Packet Access, HSUPA) be incorporated into the CELL_FACH state.Like this, under the CELL_FACH state, when downlink data has data to send, the base station is at first by high speed descending sharing channel (High Speed Downlink Shared Channel, HS-DSCH) shared control channel (SharedControl Channel for HS-DSCH, HS-SCCH) dispatch certain terminal, this terminal receives the data on the HS-DSCH in the position of scheduling indication.When sending, upstream data at first passes through to strengthen Physical Uplink Control Channel (Ehanced Random Uplink Control Channel, E-RUCCH) to the base station requests resource, then resource is permitted by E-AGCH in the base station, after obtaining permitting, terminal strengthening dedicated channel (Enhanced Dedicated Channel, E-DCH) transmitting data.That is to say strengthening under the CELL_FACH state that data transfer all is the United Dispatching that needs by the base station.
In the communication system of TD-SCDMA, under idle condition and connection status, terminal needs read apparatus message.Comprise in the system message that the residential quarter is selected and the parameter of gravity treatment, the parameter of public physic channel, the parameter of at random access and the parameter of measurement control etc.After the terminal read system message, can utilize the parameter of wherein carrying to carry out residential quarter access or resident, the residential quarter is selected and gravity treatment, at random access, the operations such as measurement.
System message is broadcasted by signaling SYSTEM INFORMATION.This signaling is to be mapped on the physical channel Primary Common Control Physical Channel (Primary common control Physical Channel, PCCPCH) to transmit.PCCPCH is fixed on No. 0 time slot (TS0) position, and needs to cover whole residential quarter, adopts conservative transmitting power, guarantees that all terminals can receive.For the system that introduces the N frequency, can there be a plurality of carrier waves a residential quarter.These carrier waves are divided into main carrier and auxiliary carrier wave, terminal both can be operated on the main carrier and also can be operated on the auxiliary carrier wave, but system message can only be broadcasted at the PCCPCH of main carrier, so if terminal works is at auxiliary carrier wave and need read apparatus message, it can only be to jump on the main carrier so, in TS0 position receiving system message.The information such as parameter that when starting up of terminal searches a suitable residential quarter and is linked into this residential quarter, need read system message to obtain the parameter of the public physic channel of this residential quarter, access at random.After terminal resides in this residential quarter, do not need read system message, receive except nonterminal network notice system message update indication or reselect to a new residential quarter.Will read in the TS0 position of main carrier the system message content of renewal when the indication of terminal receiving system information updating or after choosing a new residential quarter.
The type that SYSTEM INFORMATION comprises mainly contains three kinds: Master Information Block (MasterInformation Block, MIB), Scheduling Block (Scheduling Block, SB) and system information block (SystemInformation Block, SIB).System message broadcasting not only will send, for allow terminal can be in place with solve corresponding SIB opportunity, the scheduling of system message is extremely important.The information spinner of scheduling will be present among MIB and the SB.MIB has provided the schedule information of SB and SIB, i.e. the repetition period of SB and SIB and particular location (referring at which System Frame Number (SFN) to occur).SB has provided the schedule information of those SIB that do not carry among the MIB.SB whether occur depending on MIB in whether carried SB relevant schedule information.SIB mainly carries the content of concrete system message, have 20 kinds, the content that every kind of SIB carries is different, and what for example SIB3 carried is that the residential quarter is selected and cell reselection parameters, the parameter of the public physic channel of SIB5 band, the parameter that the measurement of carrying among the SIB11 is relevant etc.
Under the CELL_FACH enhanced situation process of system message update as shown in Figure 1, flow process is as follows:
Step 10: repetition period and the delivery time of the SIB content after radio network controller (Radio Network Controller, RNC) will upgrade by system message update request (SYSTEM INFORMATION UPDATE REQUEST) and MIB, SB, SIB are informed the base station.Represent not upgrade for the SIB that does not have in the SYSTEMINFORMATION UPDATE REQUEST message to occur, still keep original content to send;
Step 11: the system message after the base station is received after the SYSTEM INFORMATION UPDATE REQUEST message and will be upgraded in the moment of appointment and cycle sends by SYSTEM INFORMATION periodic broadcasting;
Step 12: the base station is to RNC reponse system information updating response (SYSTEM INFORMATIONUPDATE RESPONSE);
Step 13:RNC receives after the feedback of base station that Frame Protocol (FP) frame by the type2 of HS-DSCH or type3 type carries Broadcast Control Channel (Broadcast Control Channel, BCCH) categorical data (being the system message update indication) and BCCH specialized high-speed Radio Network Temporary Identifier (BCCHspecific H-RNTI) and informs that the base station transmission system information updating indicates (SYSTEM INFORMATIONCHANGE INDICATION) notification terminal read system message;
Step 14: indicate to terminal transmitting system information updating the base station, and by carrying the HS-SCCH dispatch terminal of BCCH specificH-RNTI, receive the HS-SCCH of BCCH specific H-RNTI when terminal after, receive SYSTEM INFORMATION CHANGE INDICATION in the position of appointment;
Step 15: whether terminal determines the needs read system message according to the content among the SYSTEM INFORMATION CHANGE INDICATION, if need update system message then receive MIB in the TS0 position of main carrier, the schedule information indicated by MIB reads SIB.
The below introduces the structure of time slot of TD-SCDMA system:
The TD-SCDMA system is time division multiplex system, has been divided into the time period take subframe as unit on the time shaft, as shown in Figure 2, each subframe (5ms) is divided into 7 common time slot (TS0, TS1...TS6) and 3 special time slots (DwPTS, GP, UpPTS).System message is carried out broadcast transmission at the TS0 time slot with the PCCPCH channel.
When terminal works was in N frequency system, there was such structure of time slot in each carrier wave, as shown in Figure 3.
3 can find out by reference to the accompanying drawings, if current terminal works at auxiliary carrier wave and need read system message, it just must jump to main carrier and comes receiving system message by the PCCPCH channel when TS0 so.For the terminal of only having the monocrystalline frame in the radio-frequency structure, auxiliary carrier wave is different with main carrier frequency, and the TS0 that jumps to main carrier from auxiliary carrier wave needs the regular hour, it is generally acknowledged to be more than 100 chip during this period of time, Hopping time as shown in Figure 3.If this moment, this terminal was dispatched at No. 6 time slot (TS6) of auxiliary carrier wave in the base station, the terminal part-time that need to take TS6 is finished frequency hopping so, thereby causes loss of data.

Embodiment
The problem of losing for fear of the terminal receive data, the embodiment of the invention provides a kind of terminal scheduling method, in this method, after the trigger condition that satisfies the first time slot read system message of terminal from auxiliary carrier wave to main carrier, the base station not on the auxiliary carrier wave before the first time slot and the second timeslot scheduling terminal adjacent with the first time slot.
Referring to Fig. 4, the terminal scheduling method that the embodiment of the invention provides specifically may further comprise the steps:
Step 30: the base station determines whether to satisfy the trigger condition of terminal from the auxiliary carrier wave of this terminal work at present to the first time slot read system message of the main carrier of this residential quarter, terminal place;
Step 31: after determining to satisfy described trigger condition, the base station is determined on the auxiliary carrier wave of terminal, before the first time slot and second time slot adjacent with the first time slot;
Step 32: base station selection other time slots except the second time slot;
Step 33: other timeslot scheduling terminals that the base station is being chosen.
In the step 30, the trigger condition of terminal from the auxiliary carrier wave of this terminal to the first time slot read system message of the main carrier of this terminal determined to satisfy in the base station, and its concrete mode can have following three kinds:
The first, base station determine to satisfy the trigger condition of terminal from the auxiliary carrier wave of this terminal work at present to the first time slot read system message of the main carrier of this residential quarter, terminal place after terminal transmitting system information updating indication;
The second, after the base station knows that terminal is transformed into cell forward access channel status (CELL_FACH) from cell dedicated channel status (CELL_DCH), determine to satisfy the condition of triggering terminal from the auxiliary carrier wave of this terminal work at present to the first time slot read system message of the main carrier of this residential quarter, terminal place;
The third after base station determines that terminal is carried out cell reselection, determines to satisfy the trigger condition of terminal from the auxiliary carrier wave of this terminal work at present to the first time slot read system message of the main carrier of this residential quarter, terminal place.
In the step 31, the second time slot concrete determine method can for, at first, the subframe utilized to terminal transmitting system message is determined in the base station, with in the last subframe of auxiliary the above subframe of carrier wave of terminal before the first time slot and the time slot adjacent with the first time slot, be defined as the second time slot.
Here, the subframe utilized to terminal transmitting system message can be determined according to following formula in the base station:
SFN?mod?IB_SG_REP＝IB_SG_POS
Wherein, IB_SG_REP is the repetition period of system message, and IB_SG_POS is the delivery time of system message within this repetition period.
Certainly, the base station except according to the method described above with in the last subframe of auxiliary the above subframe of carrier wave of terminal before the first time slot, and the time slot adjacent with the first time slot is defined as the second time slot, can also be with in other subframes except described last subframe on the auxiliary carrier wave of terminal, the time slot identical with the position that is confirmed as the second time slot also is defined as the second time slot, for example, the second time slot that the base station is determined according to the method described above is the TS6 among the subframe A, then can also be with the subframe B on the auxiliary carrier wave, TS6 among the subframe C etc. also is defined as the second time slot, and a kind of situation is that the TS6 with each subframe on the auxiliary carrier wave is defined as the second time slot.
In the step 32, base station selection other time slots except the second time slot, its specific implementation can be as follows:
In the subframe that cycle repetition time of base station transmitting system message on the auxiliary carrier wave of terminal comprises, choose the time slot of not identical with the position of the second time slot (being that frame number is not identical), as other time slots except the second time slot.For example, the second time slot that the base station is determined is the TS6 among the subframe A, and subframe B and subframe C were included in cycle repetition time of transmitting system message, then can choose among subframe B and the subframe C other time slots except TS6 for dispatch terminal.
Certainly, the base station also can adopt other modes to choose other time slots except the second time slot, for example choose time slot on the subframe except cycle repetition time of system message, not identical with the frame number position of the second time slot, as other time slots except the second time slot.Only need to guarantee not overlapping getting final product of other time slots of choosing and the second time slot.
Better, in order to take full advantage of system resource, after the base station determines that terminal is finished read system message, recover in the scheduling of the second time slot to terminal, namely according to the transmitting-receiving of existing mode indicating terminal in the enterprising row data of the second time slot.
Here, the base station determines that terminal finishes the mode of read system message and can adopt following two kinds:
The first after terminal has read system message, sends message to the base station and reads complete response, the base station receives this message read complete response after, determine that terminal finishes read system message;
The second, the base station starts timer determining to satisfy the auxiliary carrier wave of terminal from this terminal work at present after the trigger condition of the first time slot read system message of the main carrier of this residential quarter, terminal place, when this timer expiry, determine that terminal finishes read system message.The time of timer can be set to a value larger, enough terminal read system messages, for example can get second time value of level.
When the frame structure that adopts shown in the accompanying drawing 2, the frame number of the first time slot among the present invention is No. 0 of subframe, i.e. TS0, and the second time slot is No. 6 time slot, i.e. TS6 of subframe.Certainly, the frame number of the first time slot can be other positions in the subframe according to concrete system frame structure design, the subframe No. 5 time slot for example, and so, the second time slot is No. 4 time slot of subframe just.
