Background technology

GSM（Global System for Mobile Communications, global system for mobile communications）By long-term Development, technical maturity and network coverage ability are all very strong, therefore, field of communication technology become key technology it One.

In gsm, since the radius of society of GSM can reach 35KM, distance BS（Base Station, base station）Farther out MS（Mobile Station, mobile station）The signal sent to BS, there are wave transmissions delay, needing could by certain time The problem of reaching BS, and time delay is long can lead to such a case：The time slot for the signal that the MS that BS is received is sent is sent out with MS The time slot for the number of delivering letters does not correspond to, for example, BS can just receive the signal that MS is sent on the first slot in the second time slot, MS is caused to send out The signal sent is asynchronous with the time slot where BS received signals, therefore, postpones in order to compensate for wave transmissions, ensures BS's and MS Signal synchronizes（That is MS sends signal on the first slot, and BS receives the signal on the first slot）, MS is needed to send in advance Signal, amount in advance is TA（Time Advance, Timing Advance）.

In the prior art, MS determines that the method for TA values is as follows：

Step A：MS distributes to the TAI of the MS in BS（Timing Advance Index, Timing Advance index）It is corresponding PTCCH/U（（PTCCH Uplink, packet time lead control channel uplink；PTCCH（Packet Timing Advance control channel, packet time lead control channel））On, periodically send AB（Access Burst, access burst pulse）；

Wherein, the structure of PTCCH is as shown in Figure 1A.

Step B：BS calculates the TA values of the MS according to the AB received；

Step C：BS carries calculated TA values in TA message（Message）In be sent to MS；

Wherein, TA message is with NB（Normal Burst, Normal bursts）Form is sent, structure such as Figure 1B institutes of NB Show.

For example, MS sends AB in the position of TAI=0, then MS can most obtain newer TA values, TA in TA message2 soon The structure of message is as shown in Figure 1 C, and TA message2 are a kind of specific TA message, TA message1, TA The structure of each TA message of message2, TA message3 etc. is identical, the content of the time and carrying that only send It is different.

Step D：MS parses the TA values corresponding with the MS carried in TA message received, and according to this TA values send signal to BS.

In this step, each octet in the octet1-16 of TA message corresponds to a TAI, has also corresponded at this PTCCH/U corresponding to TAI sends the MS of signal, then the TA values carried in the octet are just the corresponding TA values of the MS.

Currently, in order to improve decoded accuracy, BS can be distributed to MS when channel is established and is used on this channel Channel estimation, the TS for improving decoded accuracy（Training Sequence, training sequence）, TS included in NB structure in, As shown in Figure 1B.

For hoist capacity, multiple MS are multiplexed on same physical channel, wherein multiple MS correspond to different TS, even if The corresponding TA values of multiple MS are carried in TA message, but only MS sends TA message institutes in the TS and BS for determining distribution When the TS of use is identical, the TA values corresponding with the MS carried in TAmessage can be just parsed, other MS cannot then be parsed The corresponding TA values carried in TA message.

Specifically, the TA update cycles of first terminal can be the interval between the updates of TA twice of first terminal, for example, As shown in Figure 4 E, due to 4 TA can simultaneously be included in a piece of news in be sent to terminal, if then the TAI of first terminal be 0 to In 3 when any value, TA update cycles of first terminal include 52 multi-frames where TAI=0 to 52 multi-frames where TAI=15；If During the TAI of second terminal is 4 to 7 when any value, then the TA update cycles of second terminal include 52 multi-frames where TAI=4 extremely 52 multi-frames where TAI=15 further include being answered with where 52 multi-frames adjacent TAI=0 place multi-frames where the TAI=15 to TAI=3 52 Frame.Terminal will send an AB, and then each TA update cycle of BS in each of itself corresponding TA update cycles The AB that terminal corresponding with the period is sent can be received only to receive the TA update cycles of each terminal The corresponding TA of AB may be differed, and similarly, for the TA update cycles of each terminal, BS can be sent in corresponding subframe Primary corresponding message, the content that only message carries may be different（I.e. TA values may be different）.

For example, as shown in Figure 4 E, it is assumed that TAI=0,1,2 ..., 15, totally 15 TAI, base station all TAI be divided into four groups, Wherein, TAI=0, TAI=1, TAI=2, TAI=3 belong to the first TAI groups, the corresponding downlink frame of each TAI in the first TAI groups The message of carrying is TA message1；TAI=4, TAI=5, TAI=6, TAI=7 belong to the 2nd TAI groups, each in the 2nd TAI groups The message of the corresponding downlink frame carryings of TAI is TA message2；TAI=8, TAI=9, TAI=10, TAI=11 belong to the 3rd TAI Group, the message of the corresponding downlink frame carrying of each TAI is TA message3 in the 3rd TAI groups；TAI=12、TAI=13、TAI= 14, TAI=15 belong to the 4th TAI groups, and the message of the corresponding downlink frame carrying of each TAI is TA message4 in the 4th TAI groups； If being assigned with four terminals simultaneously on same PTCCH：First terminal, second terminal, third terminal and the 4th terminal, base station point The TAI of dispensing four terminals is respectively TAI=0, TAI=4, TAI=8, TAI=12, and for four terminals distribute respectively TS1, TS2、TS3、TS4。

Further, since maximum of T AImax1=3 in all TAI in the first TAI groups are less than the TA of first terminal Maximum of T AImax1 '=15 in all TAI in update cycle, and meet than in all TAI in the first TAI groups most TAI groups belonging to big TAI of value TAImax1=3 more than 1, i.e. TAI groups belonging to TAI=4 are the 2nd TAI groups, the 2nd TAI groups In all TAI be all higher than maximum of T AImax1=3 in all TAI in the first TAI groups, then it is corresponding in the 2nd TAI groups TA message2 are sent using TS1 in downlink frame, which carries the TA information of first terminal.

Further, since maximum of T AImax4=15 in all TAI in the 4th TAI groups are equal to the TA of the 4th terminal Maximum of T AImax4 '=15 in all TAI in update cycle, and the TA update cycles of the 4th terminal of satisfaction is adjacent next The TAI groups belonging to minimum TAI in a TA update cycles in all TAI are the adjacent next of the TA update cycles of the 4th terminal The first TAI groups in a TA update cycles, then the 4th terminal is on TAI=15 of the TA update cycles of the 4th terminal are corresponding On row frame send AB after, base station using TS4 the TA update cycles of the 4th terminal adjacent next TA update cycles first The message of the TA values comprising the 4th terminal is sent in the corresponding downlink frame of TAI groups, therefore the 4th terminal can be from the 4th Corresponding TA values are parsed in the TAmessage1 of adjacent next TA update cycles of the TA update cycles of terminal.Class successively It pushes away, sends the TA message2 for carrying second terminal TA information in the corresponding downlink frame of the 3rd TAI groups using TS2, herein not It repeats again.

Further, in a kind of above-mentioned implement scene, further include：Third is distributed for the third terminal on the same PTCCH TAI and the 3rd TS.Wherein, the 3rd TAI and the first TAI belongs to same TAI groups, and the 3rd TS is identical as the first TS.

Specifically, the 3rd TAI groups corresponding with first terminal first belonging to the 3rd TAI if third terminal distribution As soon as the TAI groups belonging to TAI are identical, then the 3rd TS for third terminal distribution is the first TS；Alternatively, if third terminal 3rd TS of distribution is the first TS, then the 3rd TAI groups belonging to the 3rd TAI for third terminal distribution are that first terminal is corresponding The first TAI groups belonging to first TAI.

For example, if the 3rd TS distributed to third terminal is identical as the first TS, i.e., terminal is increased in same PTCCH, but TS does not increase, then when sending the TA information of third terminal, the TA information of the third terminal is carried and is sent out in first message It send.

Further, if the TS to the 4th terminal distribution on the same PTCCH is in addition to the first TS and the 2nd TS When other TS, when such as four TS, and the 4th TS and the first TS and the 2nd TS any one when being all different, then sending for the 4th end When the TA information at end, the 4th TS to be used to send the message for the TA information for carrying the 4th terminal.

In a kind of above-mentioned implement scene, by being grouped to TAI, and the corresponding TS of each TAI is identical in same TAI groups, i.e., Distribution is identical in the TS of the terminal distribution of same TAI groups, so that the TA information in the terminal of the same TAI groups can carry In same TA message, the TA updates promptness for being sent to each terminal and each terminal together is improved, while being saved and being eated dishes without rice or wine Information flow-rate.

Concrete application scene is given below in embodiment for a better understanding of the present invention, for the process of TA values instruction, makees Go out to be described in further detail（It is TA message to carry each terminal to distinguish the current message to be sent of corresponding TA values）：

Embodiment one：As shown in Figure 5A：

Step 500：TAI1, TAI2 are distributed respectively for two terminals A, B on same PTCCH；

For example, TAI=0,1,2 ..., 15, totally 16 TAI, are that terminal A distributes TAI1=1, are that terminal B distributes TAI2=8.

Step 510：The TS distributed respectively for two terminals A, B on the same PTCCH is：TS1、TS2；

Step 520：The AB that terminal A, B is sent on the same PTCCH respectively is received, and calculates separately out terminal A, B pair The TA values answered：TA1、TA2；

Specifically, terminal A, B respectively on the same PTCCH TAI1=1, send respectively in the corresponding uplink frame in TAI2=8 AB。

Step 530：The TA message1 for carrying TA1 are sent using TS1, and the TA for carrying TA2 is sent using TS2 message2。

In this step, TA1, TA2 can also be carried in TA message1, TA message2.

In this step, TS1 can be used and send TA message1, then TS2 is used to send TA message2, subsequently TA message1 are sent using TS1, it can also be to use as shown in Figure 5 B subsequently to use TS2 to send TA message2 TS1 sends TA message1, then sends TA message1 using TS1, then, sends TA message2 using TS2, then so TS2 is used to send TA message2 afterwards, in short, being exactly that TS1 at least once is respectively adopted to send the TA message1 for carrying TA1 TS2 sends the TA message2 for carrying TA2 at least once, as shown in Figure 5 C.

Embodiment two：As shown in Figure 5 D：

Step 5000：It is grouped for all TAI included on same PTCCH；

For example, all TAI included on the same PTCCH are TAI=0, and 1,2 ..., 15, totally 16 TAI, are grouped situation It is as follows：TAI=0, TAI=1, TAI=2, TAI=3 are the first TAI groups；TAI=4, TAI=5, TAI=6, TAI=7 are the 2nd TAI groups； TAI=8, TAI=9, TAI=10, TAI=11 are the 3rd TAI groups；TAI=12, TAI=13, TAI=14, TAI=15 are the 4th TAI groups.

Step 5100：Distribute TAI1 in the first TAI groups, second respectively for two terminals A, B on the same PTCCH TAI2 in TAI groups；

For example, it can be that 5, TAI=1, TAI=5 are belonging respectively to the first TAI groups and the 2nd TAI groups that TAI1, which can be 1, TAI2,.

Step 5200：The TS distributed respectively for two terminals A, B on the same PTCCH is：TS1、TS2；

Step 5300：The AB that terminal A, B is sent respectively is received, and calculates separately out the corresponding TA values of terminal A, B：TA1、 TA2；

Step 5400：It is sent and is carried in the corresponding downlink frame of adjacent next TAI groups of the first TAI groups using TS1 The first message of TA1 is sent in the corresponding downlink frame of adjacent next TAI groups of the 2nd TAI groups using TS2 and carries TA2 Second message, as shown in fig. 5e.

For example, according to the grouping in step 5000, first is sent on TAI=4,5,6,7 corresponding downlink frames using TS1 Message sends second message using TS2 on TAI=8,9,10,11 corresponding downlink frames.

In embodiments of the present invention, TAI is corresponding with uplink frame, and uplink frame is corresponding with downlink frame again, that is to say, that by upper Row frame, TAI are mapped with downlink frame indirectly, and the corresponding downlink frame of the above-mentioned TAI referred to, actually, TAI is right respectively The corresponding downlink frame of uplink frame answered.

In the embodiment of the present invention, step 300- step 320 papers are that there are two different ends on same PTCCH The case where holding and distributing different TS, in practical applications, there is also there are more than two different terminal quilts on same PTCCH The case where distributing different TS respectively, still, if different TS transmission message are respectively adopted in such case, including step 300- Therefore the technical solution of step 320 is no longer described in detail herein.

In practical applications, every time for the parameters such as terminal distribution TAI, TS when, be based on a connection TBF（Temporary Block Flow, Temporary Block Flow）It carries out, and a terminal can support multiple TBF simultaneously, wherein each TBF can be considered as One independent connection, therefore, the terminal in the application refer not only to a user, can also refer to above-mentioned refer to a TBF.
