一种上行数据传输方法及通信设备、移动台 For uplink data transmission method and a communication apparatus, a mobile station

技术领域 FIELD

[0001 ]本发明涉及通信技术领域,尤其涉及一种上行数据传输方法及通信设备、移动台。 [0001] The present invention relates to communications technologies, and in particular relates to a method for uplink data transmission and communication equipment, a mobile station.

背景技术 Background technique

[0002] 在通用分组无线业务(General Packet Rad1 System,GPRS)中,进行分组数据传输之前,需要先建立临时数据块流(Temporary Block Flow,TBF),并通过网络分配的分组资源,移动台(Moblie Stat1n,MS)和网络之间才能够进行无线链路控制(Rad1 LinkControl,RLC)数据块的传输。 Before [0002] Packet Radio Service in the General (General Packet Rad1 System, GPRS), a packet data transmission, the need to set up a temporary block flow (Temporary Block Flow, TBF), and a packet resources allocated by the network, the mobile station ( moblie Stat1n, to be able to transmit radio link control data blocks (Rad1 LinkControl, RLC) between the MS) and the network. TBF是在两个无线资源管理实体(RR)之间单向传输LLC-PDU(LLC Protocol Data Unit,LLC数据传输单元)的由]3DQKPacket Data Channel,分组数据信道)组成的一个物理连接,可由一条或多条I3DCH组成,且由于TBF是临时性,即如果没有新的数据传输,则立即释放TBF;如果再有新的数据要传输,则需要重新建立TBF。 TBF is a unidirectional transmission of LLC-PDU between two radio resource management entity (RR) (LLC Protocol Data Unit, LLC data transmission unit) by] 3DQKPacket Data Channel, packet data channels) consisting of a physical connection, by a or more I3DCH composition, and because TBF is temporary, that is, if no new data transmission, then immediately release the TBF; if no new data to be transmitted, you will need to re-establish the TBF.

[0003] 如果MS要向网络侧,如向通信设备子系统(Basic Service Set,BSS)发送上行RLC数据块,则需要先通过分组接入过程(packet access procedure)建立一个上行TBF;如果网络侧要向MS发送下行RLC数据块,则需要先建立下行TBF。 [0003] If the MS would like the network side, such as sending an uplink RLC data block to the communication device subsystems (Basic Service Set, BSS), it is necessary to establish an uplink TBF through a packet access procedure (packet access procedure); if the network side to MS transmits a downlink RLC data block is required to establish the downlink TBF. 目前,上行TBF的建立可以使用短接入,即分配固定上行传输资源;一步接入,使用动态分配资源的方法;两步接入(Twophase packet access),即可使用固定分配资源方法,也可使用动态分配方法。 Currently, an uplink TBF establishment may use short access, i.e. the fixed uplink transmission resource assignment; access step, using the method of dynamic allocation of resources; two-step access (Twophase packet access), using a fixed resource allocation method can also be dynamic allocation method. 建立TBF过程中,网络侧在向MS返回的立即指派消息MMEDIATE ASSIGNMENT中为对应于该MS的TBF分配TFI和所分配的固定资源。 TBF established procedure, the network side returns the immediate assignment message to the MS MMEDIATE ASSIGNMENT assigned TFI and the fixed allocated resources to the TBF corresponding to the MS.

[0004] TBF建立成功后,MS即可在分配的资源上传输数据块。 [0004] After successfully established TBF, MS can transmit on the allocated resources in a data block. 当发送完数据块后,需要释放所分配的资源,上行资源的释放通过“倒计数”过程实现。 After transmission of the data block, the need to release the allocated resources, the uplink resource release is achieved by a "count down" process. 即MS在所发送的RLC上行数据块中存在一个倒计数值(Countdown Value,CV),以表明当前上行TBF中尚未传送的数据块。 I.e., when the MS is a countdown value (Countdown Value, CV) in an uplink RLC data block transmitted to indicate that the current uplink TBF the data block has not been transmitted. 当未发送的RLC/MAC数据块等于系统所设定的BS_CV_MAX值,系统将执行倒计数过程。 When the value of the BS_CV_MAX unsent RLC / MAC data block set equal to the system, the system will perform countdown procedure. MS将再传送BS_CV_MAX个RLC/MAC数据块,直到CV = O,即发送最后一个数据块,当网络侧接收到该包含CV = O的RLC/MAC数据块,并且所有的RLC/MAC数据块都已经被确认完成后,向MS返回包含终结应答指示符(Final Ack Indicator)为I的上行分组确认/非确认消息(PACKETUPLINK ACK/NACK),告知MS释放上行TBF、TFI等资源。 MS Jiangzai transfer BS_CV_MAX a RLC / MAC data block, until the CV = O, i.e. sending the last data block, when the network side receives the CV = O comprising the RLC / MAC data block, and all RLC / MAC data blocks after the confirmation has been completed, the MS returns a final response indicator (Final Ack indicator) of an uplink packet I acknowledgment / negative acknowledgment message (PACKETUPLINK ACK / NACK), to inform the MS releases the uplink TBF, TFI and other resources. MS接收到此上行分组确认消息后,将传送分组控制确认消息PACKET CONTROL ACKNOWLEDGE,并释放TBF、TFI等资源;同时网络侧接收到分组控制确认消息后,该上行TBF所占用的临时数据块流标识符(TFI)资源也被释放,可重新分配给其他MS使用。 After this the MS receives an uplink packet acknowledgment message, transmit a packet control acknowledgment message PACKET CONTROL ACKNOWLEDGE, and release the TBF, resources such as the TFI; At the same time the network side receives the acknowledgment packet is a control message, the uplink Temporary Block Flow TBF identifier occupied character (the TFI) resources are released, can be reassigned to another MS use.

[0005] 综上,由于建立TBF时为该TBF分配了TFI,释放资源时需要MS和网络侧同时释放该TFI等资源,因此,在资源释放过程中采用倒计数发送数据块,并且在发送完最后一个数据块后,网络侧需要接收到MS发送的分组控制确认消息PACKET CONTROL ACKNOWLEDGE才能释放TFI等资源,从而使得数据传输过程中控制消息较多,降低了数据业务有效数据的传输效率较低。 [0005] In summary, since the TBF is established for the TFI assigned TBF, the MS and the network at the same time the need to release the TFI releases the resource and other resources, and therefore, the resource release procedure employed countdown transmission data block, and sending the after the last data block, the network need to receive the control packet sent by the MS acknowledgment message pACKET cONTROL ACKNOWLEDGE to release the TFI resources, so that the data transfer process more control messages, reducing the transmission efficiency is low traffic data valid data.

具体实施方式 Detailed ways

[0036]下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0036] below in conjunction with the present invention in the accompanying drawings, technical solutions of embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention, but not all embodiments example. 基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。 Based on the embodiments of the present invention, those of ordinary skill in the art to make all other embodiments without creative work obtained by, it falls within the scope of the present invention.

[0037]本发明实施例的上行数据传输方法通过采用固定资源分配的方式为MS分配固定资源,且不分配TFI,而通过每个数据块中携带的TLLI来区分用户,即当MS发送完数据块时,固定资源分配完毕,与现有技术的方案相比,当数据块全部接收正确时,就可以释放TBF资源,不需要MS和网络侧同时释放TBF资源,因此,不需要倒计数过程,不需要网络侧返回分组控制确认消息,从而减少了数据传输过程中的控制消息,提高数据传输的效率。 [0037] The uplink data transmission method of an embodiment of the present invention by using fixed allocated resources allocated for the MS fixed resource, and does not allocate the TFI, but distinguished by the user TLLI carried in each data block, i.e., when the MS sending the data when the block, the fixed resource allocation is completed, compared to prior art solutions, when correctly received all of the data blocks, the resource can be released TBF, the MS and the network side does not need to release the TBF resources simultaneously, it is not necessary during the countdown process, no network side returns the packet control acknowledgment message, thereby reducing the control message data transmission process, improve the efficiency of data transmission.

[0038]参见图1,为本发明的一种上行数据传输方法的第一种实施例的流程图。 [0038] Referring to Figure 1, a first embodiment of a flowchart for uplink data transmission method of the present invention. 具体实施时,本实施例的上行数据传输方法的实施过程如下: In specific implementation, the implementation process of uplink data transmission method according to the present embodiment is as follows:

[0039] Sll,通信设备为MS分配固定资源,并向MS返回TFI置空的指派消息,所述指派消息中包括分配的固定资源。 [0039] Sll, the communication device is assigned resources for the MS is fixed, and returns MS TFI blanking assignment message, a fixed resource assignment message including the assigned.

[0040]具体实施时,MS需要先根据无线链路的状态和将要发送的数据块的数目,按照固定编码方式CS-1或者初始默认编码方式计算所需要的资源块数目,从而来决定上行接入的方式:当计算得到需要的资源块数目大于8,则MS采用两步接入方式进行上行接入;当计算得到需要的资源块数目小于或者等于8,则MS采用默认为最低优先级的短接入方式进行上行接入。 [0040] DETAILED implementation, the MS need according to the number of data blocks of the state of the wireless link and to be transmitted, according to a fixed coding scheme CS-1 or the initial default number of resource blocks encoding on the need, thereby to determine an uplink connection the way: when the number of resource blocks is larger than the calculated desired 8, two-step access to the MS for an uplink access mode; when the calculated number of resource blocks required less than or equal 8, the MS the default priority is the lowest short access for uplink access. 通信设备向MS返回的指派消息包含了所分配的固定资源,优选地,还可以包括该MS的接入帧号和随机数。 Communication device comprising fixed allocated resource assignment message to the MS returns, preferably, the MS may also include a frame number and a random access number. 其中所述通信设备为可以与MS通信的设备,例如为网元、用户单元、服务器等设备。 Wherein said device is a communication device may communicate with the MS, for example, a network element, a subscriber unit, servers and other equipment.

[0041]在一具体实施例中,则当采用短接入方式时,在该步骤SI I具体实施过程如下: [0041] In a specific embodiment, the short access mode when using, in this particular embodiment step SI I as follows:

[0042] 接收MS发送来的分组信道请求消息PACKET CHANNEL REQUEST,该分组信道请求消息中包含了发送数据块所需要的资源块的数目、扩展后的随机数。 [0042] The MS receives the transmitted packet channel request message PACKET CHANNEL REQUEST, PACKET CHANNEL REQUEST message that contains the number of resource blocks of transmission data blocks needed, extended random number. MS生成分组信道请求消息PACKET CHANNEL REQUEST时会随机产生的一个随机数,该分组信道请求消息中包括优先级指示字段,由于短接入方式为默认最低优先级,因此MS将该优先级指示字段扩展为随机数,从而增长了随机数的比特位,则对应生成的随机数的值较大,降低产生相同随机数的概率,进而降低了接入冲突概率。 A random number randomly generated when the MS generates the packet channel request message PACKET CHANNEL REQUEST, the packet channel request message comprises a priority indication field due to the short access mode is the default lowest priority, and therefore MS the priority indication field extension a random number, and thus increase the number of random bits, corresponding to the generated random number is large, reducing the probability of generating the same random number, thereby reducing the probability that an access conflict.

[0043]根据所需要的资源块数目和扩展后的随机数为MS分配固定资源,并返回TFI字段置空的立即指派消息,该立即指派消息包括该MS的接入帧号、上述的扩展后的随机数,以及所分配的固定资源。 After the [0043] allocated according to the random number and the extension number of resource blocks required for the MS fixed resource, and returns the TFI field blanking immediate assignment message, the immediate assignment message includes the MS access frame number, the above-described extension random number, and the fixed allocated resources.

[0044] S12,接收MS在所述分配的固定资源上发送的至少一个数据块。 [0044] S12, the at least one data block transmitted on the allocated resources fixed receiving MS. 具体实施时,由于该指派消息中包含了所分配的固定资源,MS将根据该指派消息中的固定资源向通信设备发送数据块。 In specific implementation, since the assignment message contains the fixed allocated resources, the MS sends the data blocks to a communication apparatus based on the fixed resource assignment message.

[0045] S13,判断是否全部数据块均接收正确,若全部数据块均接收正确,则执行步骤S14,否则执行步骤S15。 [0045] S13, determines whether all data blocks are received correctly, if all data blocks are received correctly, then performing step S14, otherwise to step S15. 具体实施时,当通信设备接收到各个数据块后,会判断各个数据块是否被传输错误或者被解码错误等,并记录各个数据块的接收情况,例如接收正确或者接收错误、数据块的序列号等,若未被传输错误或者编译错误,即各个数据块接收正确,则执行步骤S14,否则执行步骤S15。 DETAILED implementation, when the communication device receives the respective data block, determines whether each data block is a transmission error or the decoding error and the like, and records the receiving condition of each data block, e.g. received correctly or a reception error, the sequence number of data block and the like, if not the transmission errors or compilation error, i.e., each data block received is correct, step S14 is executed, otherwise, executing step S15.

[0046] S14,释放TBF。 [0046] S14, the release of TBF. 具体实施时,由于在步骤Sll中没有分配TFI,因此当数据块全部接收正确后,通信设备将直接释放TBF。 In specific implementation, since there is no TFI assigned in step Sll, and thus when all the data blocks received correctly, the communication device directly released TBF.

[0047]在一具体实施例中,当采用短接入方式时,当通信设备判断出各个数据块接收正确,则直接释放TBF,且在释放TBF的同时向MS返回ACK消息,该ACK消息携带上述的TLLI。 [0047] In a particular embodiment, when using a short access mode, when the communication device determines that the respective data block correctly received, directly releasing TBF, and returns an ACK message to the MS at the same time releasing the TBF, the ACK message carries above TLLI.

[0048]在另一具体实施例中,当采用两步接入方式时,当通信设备判断出各个数据块接收正确时,直接释放TBF,不需要向MS返回ACK消息。 [0048] In another particular embodiment, when a two-step access mode, when the communication device determines that the individual receives the correct data block, direct release of the TBF, no return ACK message to the MS.

[0049]本实施例中,由于在步骤SI I中没有分配TFI,因此,不需要倒计数过程,而是直接释放TBF,从而精简了释放流程,提高了数据传输效率。 [0049] In this embodiment, since there is no TFI assigned in step SI I, therefore, the process does not need to count down, but the TBF is released directly, thereby streamlining the release process, improve the data transmission efficiency.

[0050] S15,向MS返回重传消息Packet Uplink Retransmiss1n。 [0050] S15, the MS returns to retransmit the message Packet Uplink Retransmiss1n. 执行本步骤的前提是步骤S13中通信设备判断出所接收的数据块中至少有一个数据块接收不正确。 This step is a prerequisite for performing the step S13 determines that the communication apparatus received data block in the at least one received data block is incorrect. 具体实施时,该重传消息中的ALLOCAT1N_BITMAP_LENGTH是根据该MS发送的数据块的数目进行设置,即该重传消息中包含了接收的各个块的信息,例如各个数据块被接收正确/不正确的接收情况。 In specific implementation, the retransmitted message ALLOCAT1N_BITMAP_LENGTH is set according to the number of data blocks that the MS transmitted, i.e., the retransmitted message contains information for each block received, for example, respective data blocks are received correctly / incorrectly reception conditions. 该重传消息还包括了重传资源块、重传编码方案。 The message further comprises a retransmission resource retransmission blocks, the retransmission coding scheme. 该重传消息最多67bits,可携带两个用户的重传信息。 The message retransmission up to 67bits, retransmission information can carry two users. 在一具体实施例中,当采用短接入方式时,该重传消息还可以包含与上述接收到的数据块携带的TLLI相同的TLLI。 In a particular embodiment, when using a short access mode, the message retransmission may further comprise receiving said data blocks carrying the same TLLI TLLI.

[0051] S16,接收MS根据重传消息重传来的数据块。 [0051] S16, the receiving MS message retransmission according to the retransmission of data blocks. 具体实施时,由于重传消息中包含了重传编码方案、重传资源块和各个数据块接收情况,则MS根据该重传消息按照重传编码方案进行编码,并通过重传资源块重传接收不正确的数据块。 In specific implementation, since retransmission message contains the retransmission coding scheme, retransmission resource blocks and each data block reception situation, the MS is encoded as retransmission coding scheme based on the retransmitted message by retransmission resource blocks to be retransmitted receiving incorrect data blocks.

[0052]本实施例中,当通信设备接收到重传的数据块之后,还将判断所接收的各个重传数据块是否正确,若正确则返回ACK(不携带TLLI)并释放TBF;否则再次返回重传消息(不携带TLLI)进行数据重传。 [0052] In this embodiment, when the communication device receives a retransmission data block, the retransmission will be determined each received data block is correct, if correct ACK is returned (not carry the TLLI) and release the TBF; otherwise again Back retransmission message (does not carry the TLLI) for the data retransmission.

[0053]实施本实施例的上行数据传输方法,通过采用固定资源分配的方式为MS分配固定资源,但不分配TFI,而通过TLLI来识别MS,并且当正确接收完所有数据块后直接释放所分配的固定资源。 [0053] The uplink data transmission method according to the present embodiment, by employing a fixed resource assignment assigns fixed resources for the MS, but does not assign the TFI, and to identify the MS by the TLLI, and discharging the directly when correctly received all data blocks fixed resource allocation. 即由于本实施例中在建立TBF时没有分配TFI,因此,不需要MS与网络侧同时释放资源,因此,当通信设备正确接收完所有的数据块后,直接释放所分配的固定资源,从而不需要倒计数后才释放资源,进而减少了数据传输过程中的控制消息,提高数据传输效率。 That is, since the present embodiment is not assigned TFI in the establishment of the TBF, there is no need to release the MS and the network resources at the same time, and therefore, when the communication device is correctly received all data blocks, is released directly fixed resource allocated so as not to countdown after the release of resources needed, thereby reducing the control message data transmission process, improve the data transmission efficiency.

[0054]通常,在数据块传输过程中,网络侧需要在首次接收到携带TLLI的数据块后,以及全部数据接收完后,分两次向MS返回ACK/NACK消息,从而使得数据传输过程中控制消息较多,降低了数据业务有效数据的传输效率。 [0054] Generally, a data block transmission, the network needs in the first TLLI carries the received data blocks, and all the data is received, it returns twice ACK / NACK message to the MS, so that the data transfer process more control messages, reducing the efficiency of the data transmission valid data traffic. 为了提升数据业务有效数据的传输效率,本发明还提供了上行数据传输方法的第二种实施例。 To improve the data transmission efficiency of significant data traffic, the present invention also provides a second upstream data transmission method embodiments.

[0055]参见图2,为本发明的上行数据传输方法的第二种实施例的流程图,具体实施时,本实施例的上行数据传输方法也包括上述实施例的步骤Sll,且当采用短接入方式时,本实施例的上行数据传输方法还可以在步骤Sll之后,包括步骤: [0055] Referring to Figure 2, a flowchart of a second embodiment of an uplink data transmission method of the present embodiment of the invention, the specific embodiment, the uplink data transmission method according to the present embodiment also includes the step Sll the above embodiment, and when using a short when the access mode, the uplink data transmission method according to the present embodiment may further embodiment after step Sll, comprising the steps of:

[0056] S121,接收MS根据指派消息发送来的至少一个数据块,且每一个数据块均携带有唯一标识发送该数据块的MS的TLLI。 [0056] S121, the received data block at least one MS according to an assignment message transmitted, and each data block are sent carries the TLLI uniquely identifies the MS block.

[0057]具体实施时,当通信设备接收首次接收到携带TLLI的数据块时,根据该数据块的TLLI识别固定资源分配给了哪个用户,但不会返回ACK/NACK消息,而是继续接收MS后续发送来的均携带TLLI的数据块。 [0057] When particular embodiment, when the communication device receives a first received data block carrying the TLLI, identified according to the TLLI fixed resource block is assigned to which user, but does not return ACK / NACK messages, but continues to receive the MS subsequent transmitted data blocks are carried TLLI.

[0058] S131,根据各个数据块的TLLI判断是否发生接入冲突,若未发生接入冲突,则执行步骤SI 3,否则执行步骤SI 51。 [0058] S131, each data block according to the TLLI is determined whether the access conflict occurs, if no access conflict occurs, the step SI 3, otherwise step SI 51.

[0059]具体实施时,判断首次接收的数据块的TLLI与后续接收的各个数据块的TLLI是否相同,若相同,则未发生接入冲突,在步骤S13中,进一步判断各个数据块全部接收正确;否贝IJ,即若后续接收的某一个数据块携带的TLLI与首次接收的数据块的TLLI不同,则发生了接入冲突,判断各个数据块未被全部正确接收,不需要解码该数据块或者判断其是否被传输错误等,且在全部数据块接收完之后,执行步骤S151。 [0059] When particular embodiment, each data block TLLI TLLI received first data block is determined and subsequently received is the same, if the same, then the access collision did not occur, in step S13, it is further determined all correctly received data blocks each ; No shell IJ, i.e. different TLLI TLLI of the data block received one of the first data block if the subsequently received carried in the access conflict occurs, each data block is determined not all correctly received, the data block does not need to decode or whether it is a transmission error or the like, and after all data blocks receiving end, step S151. 其中在步骤S131中可以通过比较接收到的数据块的TLLI是否相同来判断是否发生接入冲突,在步骤S13中可以通过判断数据块是否被传输错误/解码错误等方法来判断数据块是否接收正确,并且可以在步骤S131之后再进一步确定数据块接收正确。 Wherein the same can be judged by comparing whether the received data block is the TLLI access collision occurred in step S131, whether or not in step S13 can be transmitted errors / decoding errors is determined by the method determines whether the data block correctly received data block and it may be further determined that the data blocks received correctly after step S131.

[0060] S14,直接释放TBF,并向MS返回携带相同TLLI的ACK消息。 [0060] S14, immediate release TBF, returns an ACK message to the MS's TLLI carrying the same.

[0061 ] S151,向MS返回携带TLLI的重传消息。 [0061] S151, returns a retransmission message carrying the TLLI to the MS. 具体实施时,执行该步骤的前提为数据接收不正确,即后续各个数据块的TLLI与第一数据块的TLLI相同,但至少有一个数据块被传输错误/解码错误;或者发生了接入冲突,即后续各个数据块中至少有一个数据块的TLLI与第一个数据块的TLLI不相同。 In specific implementation, this step is provided to the data receiver is incorrect, i.e., the respective TLLI subsequent data block with the same TLLI the first data block, but there is at least one data block transmission errors / decoding errors; access collision occurs, or , i.e., each subsequent data block TLLI TLLI at least one data block and the first data block is not the same.

[0062]本实施例中还包括步骤S16,其与上述实施例的步骤S16相同,即接收重传数据块。 [0062] The present embodiment further includes step S16, the same as the embodiment described above step S16, i.e., the retransmitted data block is received.

[0063]本实施例中,当判断全部数据块接收正确时,通信设备才向MS返回一个包含TLLI的ACK消息,或者当判断发生了接入冲突或者各个数据块未被全部接收正确时,也需要全部数据块接收完之后才返回一个重传消息,不需要在首次接收到数据块时就向MS返回一次ACK消息,再在最后返回一次ACK消息,即不需要返回两次ACK消息,从而进一步减少了数据传输过程中的控制消息,提高了有效数据传输效率。 [0063] In this embodiment, when all the data blocks received correctly determined, the communication device only returns an ACK message containing the TLLI to the MS, or when it is determined access collision occurred or not each of all the data blocks received correctly, and need not return all the data blocks after receiving a completion message retransmission, does not require a return ACK message to the MS upon receiving the first data block, then the last time return ACK message, i.e., no return ACK message twice, thereby further reducing the control message data transmission process, increasing the effective data transmission efficiency. 同时本实施例中通过该包含TLLI的ACK消息告知MS释放上行TBF,从而使得MS收到该ACK消息后,将该ACK消息中的TLLI与自身的TLLI比较,若相同,则通信设备所接收的数据块均为该MS发送的,即说明没有发生接入冲突,MS接收到该ACK消息后直接释放所分配的固定资源;否则,通信设备所接收的数据块不为该MS发送的,而是其他MS发送的,数据传输不成功。 While the present embodiment, to inform the MS releases the uplink TBF through the ACK message contains the TLLI, so that the MS receives the ACK message, the ACK message with its own TLLI TLLI comparison, if the same, then the communication device received the data blocks are sent by the MS, i.e. illustrate the access conflict does not occur, is released directly fixed allocated resources after the MS receives the ACK message; otherwise, the data block is not received by the communication device MS that transmitted, but other MS transmits the data transmission was unsuccessful.

[0064]为了避免无线链路突然恶化时,数据传输一直不成功,但某一用户持续占用网络资源的情况,本实施例的上行传输数据方法,还可包括步骤: [0064] In order to prevent sudden deterioration in a radio link, data transmission has been successful, but a case where the user continues to network resources, the uplink data transmission according to the method of the present embodiment, further comprising the steps of:

[0065]在所述移动台根据所述重传消息向通信设备重传数据块的过程中,根据上行无线链路的状态,动态调整最大重传次数。 [0065] The radio uplink state dynamically adjusting the maximum number of retransmissions during retransmission data block to a communication device in the mobile station according to the retransmission message. 所述重传消息包括最大重传次数。 The retransmission message including maximum number of retransmissions. 执行该步骤的前提为步骤S13中判断出该MS发送的数据块接收不正确或者发生了接入冲突。 Provided that step is performed in step S13 is judged that the MS transmits the data block is received correctly or not the access conflict occurs. 具体实施时,通信设备会实时监测上行无线链路的状态,并得到该上行无线链路相应的状态报告等,从而根据该上行无线链路的状态动态调整向移动台返回重传消息的次数,即动态调整最大重传次数,例如当上行无线链路的质量较好时,最大传输次数较小,当上行无线链路的质量较差时,适当增大最大重传次数,避免了某一用户持续占用网络资源,进一步提高了有效数据的传输效率,同时提高信道利用率。 In specific implementation, the communication device in real-time monitoring of the state of the uplink radio link, and to give a respective radio link in the uplink status report, so as to return the number of retransmissions of the message to the mobile station an uplink radio link dynamically adjusted based on a state, That is dynamically adjusted maximum number of retransmissions, for example, when uplink radio link quality is better, the smaller the maximum number of transmissions, when poor uplink radio link quality, properly increase the maximum number of retransmissions, a user is avoided Length network resources, to further improve the transmission efficiency of significant data, while improving channel utilization. 例如,当MS要发送4个数据块,误码率为10%时,可设置最大重传次数为2,即当移动台根据首次反馈的重传消息重传的数据块仍接收不正确时,通信设备还可发送一次重传消息,如果再次重传的数据块仍接收正确,则数据传输成功,若仍接收不正确,则发送重传消息,即不再重传数据块了,这样数据传输成功的概率是93.06 若误码率为20%,则可设置最大重传次数为3,即可向移动台发送两次重传消息,其数据传输成功率为76.16%。 For example, when the MS to be transmitted four data blocks, the bit error rate of 10%, maximum number of retransmissions may be set to 2, i.e. when the mobile station still receives the data blocks to be retransmitted first message retransmission feedback incorrect, the communication device further transmits a retransmission message, if the retransmitted data block again is still correctly received, the data transmission is successful, if still not received correctly, a retransmission is sent a message, i.e., no retransmission data block, and so data transmission 93.06 is the probability of success when the error rate of 20%, maximum number of retransmissions may be set as 3, can send two messages to the mobile station retransmits its data transmission success rate of 76.16%.

[0066]参见图3,为本发明的上行数据传输方法的第三种实施例的流程图,具体实施时,本实施例的上行数据传输方法具体包括如下步骤: [0066] Referring to Figure 3, a flowchart of a third embodiment of an uplink data transmission method of the embodiment of the present invention, the specific embodiment, the uplink data transmission method according to the present embodiment includes the following steps:

[0067] S31,MS接收通信设备发送的指派消息,所述指派消息包括为所述移动台分配的固定资源,所述指派消息中TFI字段置空。 [0067] S31, MS communication device receiving the assignment message, the resource assignment message includes a fixed allocation for the mobile station, the assigned TFI field blanking message. 具体实施时,MS首先根据无线链路的状态和将要发送的数据块数目,按照固定编码方式CS-1,或者初始默认编码方式计算所需要的资源块数目,从而确认上行接入的方式:若所需要的资源块数目大于八时,将采用两步接入方式进行上行接入;若所需要的资源块数目小于或者等于八时,将采用默认为最低优先级的短接入方式进行上行接入。 In specific implementation, the MS firstly according to the state of the radio link and the number of data blocks to be transmitted, according to a fixed coding scheme CS-1, or the initial default encoding on the number of resource blocks required to confirm the uplink access mode: if when the required number of resource blocks is greater than eight, the two-step approach to the access uplink access; if required number of resource blocks smaller than or equal to eight, the default is the lowest priority access scheme for uplink short contact into. 该指派消息包括了通信设备根据需要资源块数目分配的固定资源、该MS的接入帧号和随机数。 This fixed resource assignment message includes a communication apparatus according to the required number of allocated resource blocks, the MS access frame number and a random number.

[0068]在一具体实施例中,当采用短接入方式时,则该步骤S31具体实施过程如下: [0068] In a particular embodiment, when using a short access mode, the step S31 the specific implementation process is as follows:

[0069]向通信设备发送分组信道请求消息,该分组信道请求消息包括扩展后的随机数以及发送数据块所需要资源块的数目。 [0069] transmitting a packet channel request message to the communication device, the packet channel request message includes a random number and transmitting the extended data block number of resource blocks required. 具体实施时,由于短接入方式默认为最低优先级,因此,MS会将生成分组信道请求消息中的优先级指示字段扩展为随机数,增长了随机数的比特位,从而对应生成的随机数的值较大,降低产生相同随机数的概率,进而降低了接入冲突概率。 In specific implementation, the short access because the default mode is the lowest priority, therefore, the MS will generate a packet channel request a priority indication field in the message is extended random number, increased bit random number, a random number generated so as to correspond the larger the value, reducing the probability of generating the same random number, thereby reducing the probability that an access conflict. 当通信设备接收到该分组信道请求消息后,将立即根据所需资源块数目为该MS分配固定资源,并返回TFI字段置空的立即指派消息,该立即指派消息还包括了MS的接入帧号、上述扩展后的随机数,以及所分配的固定资源。 When the communication device receives the packet channel request message, according to the desired number of allocated resource blocks immediately MS for a fixed resource, and returns the TFI field blanking immediate assignment message, the immediate assignment message further includes an MS access frame number, the random number after the expansion, and the fixed allocated resources.

[0070]根据该指派消息中扩展后的随机数和接入帧号判断所分配的固定资源是否为分配给本MS的,否则,该MS可重新向通信设备发送分组信道请求消息以重新建立TBF。 [0070] The fixed resource determination random number and an access frame number after extended the assignment message allocated if assigned to present the MS, otherwise, the MS may re-request message to the communication device transmits a packet channel to re-establish the TBF .

[0071] S32,在所述分配的固定资源上向通信设备发送至少一个数据块。 [0071] S32, the at least one data block transmitted to the communication device on the fixed resource allocation. 具体实施时,MS会先根据通信设备返回的ACK消息中的TLLI (短接入方式时)或者分组上行指派消息中的TLLI (两步接入方式时)判断是否发生接入冲突,若没有发生接入冲突,则MS根据该指派消息中的通信设备为其所分配的固定资源向通信设备发送至少一个数据块;若发生了接入冲突,则数据传输失败。 In specific implementation, the MS will first according to (short time access) communication device returns the ACK message in an uplink assignment message or a packet TLLI in TLLI (2-step access mode) determines whether the access conflict occurs, does not occur if access collisions, the MS of its allocated resource fixed transmit at least one data block to the communication device based on the assignment message communication device; if an access conflict occurs, the data transmission fails. 在一具体实施例中,当采用两步接入方式时,当发送完数据块之后,立即启动定时器进行计时。 In a particular embodiment, when a two-step access mode, when sending the data block, the timer starts counting immediately. 本实施例中当数据传输失败时,该MS可重新发送分组信道请求以建立TBF。 When the present embodiment, when the data transmission fails, the MS may re-transmit the packet channel request to establish the TBF.

[0072] S33,当各个数据块全部被正确接收时,释放TBF。 [0072] S33, when the respective blocks are all correctly received, released TBF. 具体实施时,通信设备接收到数据块时,会判断该数据块是否全部接收正确,即是否被传输错误或者被解码错误等,并记录各个数据块的接收情况,例如接收正确或者接收错误、数据块的序列号等。 When particular embodiments, the communications device receives the data block, it determines whether the data blocks all correctly received, i.e., whether the error in the transmission or the decoding error and the like, and records the receiving condition of each data block, e.g. received correctly or a reception error, the data serial number block.

[0073]在一具体实施例中,当采用短接入方式,且通信设备正确接收到该MS发送来的数据块时,则该步骤S33具体实施过程如下: [0073] In a particular embodiment, when using a short access mode, and the communication apparatus correctly receives the data block transmitted to the MS, in step S33 the specific implementation process is as follows:

[0074]接收通信设备返回的ACK消息,该ACK消息携带有TLLI。 [0074] ACK message returned by the receiving communication apparatus, the ACK message carries the TLLI.

[0075]判断该TLLI与该MS自身的TLLI是否相同,若是则释放TBF;否则,重新向通信设备发送分组接入请求消息。 [0075] Analyzing the TLLI itself is the same as the TLLI the MS, if the TBF is released; otherwise, resending a packet access request message to the communication device.

[0076]在另一具体实施例中,当采用两步接入方式,且通信设备正确接收到该MS发送来的数据块时,则该步骤S33具体实施过程如下: [0076] In another particular embodiment, when a two-step access mode, and the communication apparatus correctly receives the data block transmitted to the MS, then the step S33, the specific implementation process is as follows:

[0077]若在预设的时间内该MS没有收到通信设备返回来的重传消息,则继续计时,直到计时达到预设的时间则释放TBF。 [0077] If the MS does not receive a communication device within a preset time to return to the message retransmission, timing is continued until the time reaches a predetermined time is released TBF.

[0078] S34,当所述至少一个数据块接收不正确时,接收通信设备返回来的重传消息,并根据该重传消息重传数据块。 [0078] S34, when the at least one data block received is incorrect, the receiving communication apparatus returns the message to the retransmission, and the retransmission data block according to the retransmission message. 具体实施时,由于该重传消息包括了各个数据块的接收情况和重传编码方案、重传资源块等,即通信设备通过该重传消息指示数据的接收情况和重传资源块,MS可得到的哪些数据块出错,以及重传的资源块等,从而直接按照重传编码方案进行编码,并通过重传资源块重传通信设备接收不正确的数据块,提高了数据传输效率。 In specific implementation, since the retransmitted message includes receiving case and retransmission coding scheme for each data block, a retransmission resource blocks, i.e., the communication device indicating data through the retransmission message reception situation and the retransmission resource block, the MS may which blocks obtained error, and the retransmission resource blocks to be encoded directly in accordance with the retransmission coding scheme, and the communication device receiving the retransmission of incorrect data blocks by retransmission resource blocks to improve the data transmission efficiency.

[0079]在一具体实施例中,当采用短接入方式时,该重传消息还携带有TLLI,则该步骤S34具体实施过程如下:判断该重传消息中的TLLI与该MS自身的TLLI是否相同,若是,则根据该重传消息重传数据块;若不相同,则重新向通信设备发送分组信道请求消息。 [0079] In a particular embodiment, when using a short access mode, the message further carries a retransmission TLLI, the specific implementation process, step S34 follows: determining that the message is retransmitted to the MS itself TLLI TLLI are the same, and if yes, according to the retransmission data block retransmitted message; if the same, then re-transmitting the packet channel request message to the communication device.

[0080]在另一具体实施例中,当采用两步接入方式时,接收到重传消息后停止计时,并根据该重传消息按照重传编码方案进行编码,并通过重传资源块重传接收不正确的数据块;且当重传完数据块之后又开始计时,直到再次接收到重传消息或者计时到达预设时间时,定时器停止计时。 [0080] In another particular embodiment, when a two-step access mode, after receiving the message retransmission timer is stopped, and encoded according to the encoding scheme based on the retransmission message retransmission, and retransmission resource blocks by weight pass the received data block is not correct; and when after the completion of the retransmission data block and begin timing until a message is received again or a retransmission timer reaches a predetermined time, the timer stops counting.

[0081]本发明实施例的上行数据传输方法通过采用固定资源分配的方式为MS分配固定资源,但不分配TFI,而通过TLLI来识别MS,并且当通信设备正确接收完所有数据块,MS接收到通信设备返回的ACK消息后直接释放所分配的固定资源,或者定时达到后直接释放所分配的固定资源。 [0081] The uplink data transmission method of an embodiment of the present invention is dispensed through the use of fixed resource allocation for the MS fixed resource, but does not assign the TFI, and to identify the MS by the TLLI, and when the communication apparatus correctly received all data blocks, MS receiver ACK message to the communication device returns directly to the fixed allocated resource release, timed or immediate release reached after a fixed resource allocated. 即由于本实施例中在建立TBF时没有分配TFI,因此,不需要MS与网络侧同时释放资源,因此,可直接释放所分配的固定资源,从而不需要倒计数,进而减少了数据传输过程中的控制消息,提高数据传输效率。 That is, since the present embodiment is not assigned TFI in the establishment of the TBF, there is no need to release the MS and the network resources at the same time, therefore, be secured directly to the release of allocated resources, so that no count down, thereby reducing the data transfer process control messages, improving data transmission efficiency.

[0082]参见图4,为本发明的上行数据传输方法的第四种实施例的流程图。 [0082] Referring to FIG 4, a fourth uplink data transmission method of the present invention, a flow diagram of the embodiment. 具体实施时,本实施例的上行数据传输方法也包括上述实施例的步骤S31,当采用短接入方式时,本实施例的上行数据传输方法还包括步骤: In specific implementation, the uplink data transmission method according to the present embodiment also includes the above-described step S31 embodiment, when using a short access mode, the uplink data transmission method of this embodiment further comprises the step of:

[0083] S321,在所述分配的固定资源上向通信设备发送至少一个数据块,且每个数据块均携带有唯一标志有该MS的TLLI。 [0083] S321, transmits at least one data block to the communication device on the allocated resources secured, each data block and each carrying a unique identifier with a TLLI of that MS.

[0084] S331,当全部数据接收正确时,接收通信设备返回的携带相同TLLI的ACK消息。 [0084] S331, when all the data is correctly received, the receiving communication apparatus returns an ACK message carries the same TLLI. 具体实施时,由于通信设备接收到MS发送的各个数据块时,需要根据数据块的TLLI判断是否发生接入冲突,并判断各个数据块接收是否正确,当未发生接入冲突且全部接收正确时,通信设备将返回MS—个携带TLLI的ACK消息。 In specific implementation, the communication device due to the respective received data block sent by the MS, TLLI need to access the data block determines whether collision occurs, and determines whether each received data block is correct, when an access conflict does not occur and all correctly received , the communication device returns an ACK MS- TLLI carries a message.

[0085] S332,判断该ACK消息中的TLLI与该MS自身的TLLI是否相同,若是,则执行步骤S333,即释放TBF,否则重新发送分组信道请求消息。 [0085] S332, determines whether the ACK message TLLI itself is the same as the TLLI the MS, if yes, executes step S333, i.e. the release of the TBF, else retransmit the packet channel request message.

[0086]当通信设备判断出未发生接入冲突,但不是全部数据块均接收正确,或者发生接入冲突时,本实施例的上行数据传输方法还包括步骤: Uplink data transmission method [0086] When the communication device determines that access collision did not occur, but not all the data blocks are received correctly, or access collision occurs, the present embodiment further comprises the step of:

[0087] S341,接收携带TLLI的重传消息,并根据该重传消息重传接收不正确的数据块。 [0087] S341, the received message carrying the TLLI retransmission, and retransmission of incorrect data blocks received based on the message retransmission. 具体实施时,首先判断该重传消息中的TLLI与该MS自身的TLLI是否相同,若是,则根据该重传消息重传数据块;否则重新向通信设备发送分组信道请求消息。 When particular embodiments, determining that the first message is retransmitted TLLI itself is the same as the TLLI the MS, if yes, the retransmission data block according to the retransmission message; otherwise repeat request message to the communication device transmits a packet channel.

[0088]本实施例中,在发送完所有的数据块或者发送完重传数据块时,还可启动计时器进行计时,以及在接收到通信设备发送来的上行分组确认消息或者重传消息时停止计时,从而避免数据传输不正确时,该MS—直占用资源。 [0088] In this embodiment, when after sending all the data blocks transmitted or retransmitted data block is finished, the timer is timed in the upstream acknowledgment message and receiving a communication packet transmitted to the device or to start a retransmission message may also when stop the clock in order to avoid incorrect data transmission, the MS- straight footprint.

[0089]本实施例的上行数据传输方法通过在MS发送完数据后,通信设备才返回相应的ACK消息或者重传消息,从而避免返回两次ACK/NACK消息,即进一步减少了数据传输过程中的控制消息,进一步提高小数据传输的效率。 Uplink data transmission method [0089] according to the present embodiment after transmission of the data by the communication device does not return an ACK message corresponding retransmit message or the MS, which avoids return two ACK / NACK message, i.e. to further reduce the data transfer process the control message further improve the efficiency of data transmission is small.
