Description

终端、网络设备和随机接入过程中的数据传输方法 技术领域
本发明涉及无线通信技术,尤其涉及一种终端、网络设备和随机接入过程中的数据传输方法。
背景技术
无线通信中,通过随机接入过程,终端得以进行数据的传输。以通用移动通信系统(Universal Mobile Telecommunications System,UMTS)为例,在随机接入过程中,作为终端的用户设备(User Equipment,UE)UE在物理随机接入信道(Physical Random Access CHannel,PRACH)发送接入签名(signature)之后,会在对应的时间点解析捕获指示信道(Acquisition Indicator CHannel,AICH),以获取随机接入的结果。
目前,在UMTS系统中,若UE接收到AICH发送的正反馈(ACK),则UE在通过竞争得到的资源上仅能发送一个传输时间间隔(Transmission Time Interval,TTI)的数据。
如图1所示,前导(preamble)是由signature生成的,该signature即为UE在PRACH上发起随机接入过程时选择的接入签名。消息部分(Message part)是UE在获得AICH的ACK之后,实际发送的数据,其中TTI的长度可为10ms,也可为20ms。
由于随机接入之后,UE仅可发送一个TTI的数据,数据量大小有限,因此,如果UE需要发送的数据包较大,就需要进行多次随机接入过程,传输多个TTI的数据,这样,会增加数据包传输的时延。
综上,目前在随机接入过程中,若终端要传输较大的数据包,传输时延较大。

具体实施方式
本发明实施例提供一种终端、网络设备和随机接入过程中的数据传输方法,用以解决目前随机接入过程后,终端在传输较大的数据包时,传输时延较大的问题。
本发明实施例中,终端向基站发送第一指示信息,指示:终端在本次随 机接入过程中传输多个TTI的数据,基站根据收到的该第一指示信息,确定终端在本次随机接入过程中传输多个TTI的数据。这样终端就可以在一次随机接入过程中传输多个TTI的数据。
进一步,基站可以在终端传输该多个TTI的数据期间,不将该终端传输该多个TTI的数据时使用的码道分配给其他终端使用,从而保证了终端的数据传输。
进一步,终端可在向基站发送上述第一指示信息之前,接收RNC发送的第三指示信息,该第三指示信息用于指示允许所述终端在本次随机接入过程中传输多个TTI的数据,终端收到该第三指示信息后,确定需要在本次随机接入过程中向基站传输多个TTI的数据时,向基站发送上述第一指示信息。
下面,结合附图对本发明实施例进行详细说明。首先介绍本发明实施例提供的无线通信系统,然后介绍本发明实施例提供的终端、基站和无线网络控制器,最后介绍本发明实施例提供的随机接入过程中的数据传输方法,以及指示信息的方法。
图2为本发明实施例提供的无线通信系统的结构示意图。如图2所示,该无线通信系统包括:
终端201,用于接收无线网络控制器203发送的第三指示信息,该第三指示信息指示允许终端在一次随机接入过程中传输多个TTI的数据;以及在确定在本次随机接入过程需要向基站202传输多个TTI的数据时,向基站发送第一指示信息,该第一指示信息指示终端201在本次随机接入过程中传输多个TTI的数据;
基站202,用于接收终端201发送的第一指示信息,根据第一指示信息确定终端201在本次随机接入过程中传输多个TTI的数据;
无线网络控制器203,用于向终端201发送上述第三指示信息。
图3为该无线通信系统中终端201、基站202和无线网络控制器203之间消息交互的流程图。如图3所示,该流程包括如下步骤:
S301:无线网络控制器203向终端201发送第三指示信息,指示允许终端 201在一次随机接入过程中传输多个TTI的数据;
S302:终端201确定在本次随机接入过程中需要传输多个TTI的数据;
S303:终端201向基站202发送第一指示信息,指示终端201在本次随机接入过程中传输多个TTI的数据。
基站202收到终端201发送的数据之后,将收到的数据处理后转发给无线网络控制器203。
本发明实施例提供的无线通信系统的通信制式可包括但不限于如下通信制式:
全球移动通信系统(Global System of Mobile communication,GSM)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access,TD-SCDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、时分双工-长期演进(Time Division Duplexing-Long Term Evolution,TDD LTE)、频分双工-长期演进(Frequency Division Duplexing-Long Term Evolution,FDD LTE)、长期演进-增强(Long Term Evolution-Advanced,LTE-advanced)等。
终端201可包括但不限于如下类型的终端:手机、平板电脑、个人数字助理(Personal Digital Assistant,PDA)、销售终端(Point of Sales,POS)、车载电脑等。
若无线通信系统的通信制式为GSM,则终端201为移动台(Mobile Station,MS),基站202为基站收发信机(Base Transceiver Station,BTS),无线网络控制器203为基站控制器(Base Station Controller,BSC);
若无线通信系统的通信制式为TD-SCDMA或WCDMA,则终端201为UE,基站202为节点B(NodeB,NB),无线网络控制器203为无线网络控制器(Radio Network Controller,RNC);
若无线通信系统的通信制式为TDD LTE或FDD LTE,由于LTE系统中网络架构采用扁平化处理,基站和无线网络控制器合二为一,称为演进节点B(evolved NodeB,eNB),则基站202和无线网络控制器203的操作均可由eNB 完成。即由eNB向终端201发送第三指示信息,终端201在确定需要在一次随机接入过程中传输多个TTI的数据时,再向eNB发送第一指示信息。
以本发明实施例提供的无线通信系统的通信制式为WCDMA为例,以往,在有大数据包发送的时候,会直接将终端迁移到小区专用信道(CELL Dedicated CHannel,CELL_DCH)状态,不采用随机接入的方式进行数据包的发送,但是这样会导致状态迁移的发生。
采用本发明实施例,可不必进行状态迁移,即可实现多个TTI的数据的发送,提高了数据发送的效率。
并且,由于当终端迁移到CELL_DCH状态时,会占用小区的专用信道等资源,通过采用本发明实施例,可在不占用小区专用信道资源的情况下即可实现数据的发送,节省了小区资源。
此外,终端需要通过信令传输才能迁移到CELL_DCH状态,这提高了在信令传输过程中终端无线链路失败的概率,因此,采用本发明实施例还能够提高终端数据发送的成功率。
本发明实施例突破了现有的数据发送机制,巧妙地利用了随机接入过程完成了大数据包的发送,提高了数据发送的成功率、效率,同时也节省了小区的专用信道等资源。
无线网络控制器203在向终端201发送第三指示信息时,可针对终端201即将发起的随机接入过程发送该指示信息,也可针对终端201发起的所有随机接入过程发送该指示信息。
一种可能的情形是,无线网络控制器203通过终端发起的小区更新过程,获知终端201所在的小区所属的基站202,若无线网络控制器203确定该基站202具备在一次随机接入过程中接收终端201发送的多个TTI的数据的能力时,向该终端201发送上述第三指示信息。无线网络控制器203可以在终端发起的小区更新过程中发送该第三指示信息。也可以在该小区更新过程之后向终端201发送该第三指示信息。
另一种可能的情形是,无线网络控制器203若确定基站202具备在一次 随机接入过程中接收终端201发送的多个TTI的数据的能力时,在该基站202下的小区内,通过系统消息向接入该小区的终端201发送该第三指示信息。
以上列举的两种可能的情形仅为示例,实际实现时不限于此,只要能实现无线网络控制器203向终端201发送上述第三指示信息即可。
可选地,该第三指示信息可包括下列信息中的至少一种:
信息1、允许终端在一次随机接入过程中传输的最大TTI的数目;
信息2、允许终端在一次随机接入过程中传输多个TTI的数据的指示信息;
信息3、数据量门限值;
信息4、终端发送接入前导时使用的物理资源的信息与终端在一次随机接入过程中传输的多个TTI的TTI数目的对应关系。
信息5、终端发送接入前导时使用的物理资源的信息。
其中,可选地,上述信息4和信息5中,“终端发送接入前导时使用的物理资源的信息”可包括如下三项信息中的至少一种:
终端向基站发送的接入签名;
终端在向基站发送接入前导时使用的PRACH码道;
终端在向基站发送接入前导时使用的接入时隙。
上述“终端发送接入前导时使用的物理资源的信息”的几种可选的实现方式,也适用于本发明实施例中其他涉及“终端发送接入前导时使用的物理资源的信息”的部分。
若第三指示信息包括信息2和信息3,则终端201在自身缓存的需要在一次随机接入过程中发送的数据的数据量大于信息3指示的数据量门限值时,确定需要在一次随机接入过程中发送多个TTI的数据。
若第三指示信息包括信息4,终端201确定在一次随机接入过程中需要传输X个TTI的数据,终端201根据X,以及信息4确定终端201在本次随机接入过程中向基站202发送的接入签名;终端201向基站202发送该确定的接入签名。基站202根据收到的接入签名,确定终端201发送的TTI的数目X。
若第三指示信息包括信息5,则一种可选的实现方式是:终端201预先知道允许终端发送的TTI的数目和终端发送接入前导时使用的物理资源的对应关系,终端201收到该信息5后,根据预先知道的上述对应关系,即可知道自身在本次随机接入过程中可发送的TTI的数目,若确定可发送多个TTI,则实现了无线网络控制器203通知终端201可在一次随机接入过程中发送多个TTI的数据。其中,终端201可通过无线网络控制器203预先发送的控制信息,预先获知上述对应关系。
在本实施例中,终端201向基站202发送的接入签名包含终端将接入签名重复256次组成接入前导(preamble)向基站发送的方式。
可选地,终端201通过上述步骤S301收到该第三指示信息后,执行步骤S302,确定无线网络控制器203允许自身在一次随机接入过程中发送多个TTI的数据,并进一步确定是否满足下述条件,在满足下述条件中的一项或多项时,确定在本次随机接入过程中向基站传输多个TTI的数据:
条件1、终端的缓存数据量大于或等于数据量门限值;
条件2、终端到基站的路损小于或等于预设的路损门限值;
条件3、终端所在的小区的负载小于或等于预设的小区负载门限值。
比如,一种可能的实现方式是:在满足条件1时,终端201确定在本次随机接入过程中向基站传输多个TTI的数据;
再比如,另一种可能的实现方式是:在同时满足条件1和条件2时,终端201确定在本次随机接入过程中向基站202传输多个TTI的数据。
以上两种可能的实现方式仅为示例,在具体实现时,终端201在收到第三指示信息后,根据自身的数据缓存情况和/或无线环境信息等,确定是否在本次随机接入过程中向基站202传输多个TTI的数据。
可选地,图3所示的流程中,步骤S303中,终端201向基站202发送的第一指示信息除了指示基站202终端201在本次随机接入过程中传输多个TTI的数据之外,还用于指示基站202:
该多个TTI具体为X个TTI,X为正整数;或
终端201在本次随机接入过程中,当前TTI之后还有对应于另一个TTI的数据要传输;或
终端201在本次随机接入过程中,当前TTI为传输的最后一个TTI。
终端201在向基站指示在本次随机接入过程中传输多个TTI的数据等相关信息时,可以采用如下四种方式:
【方式一】
终端201在发送接入前导时,向基站202发送第一指示信息,指示终端201要在本次随机接入过程中传输多个TTI的数据。
对于方式一,一种可能的实现方式是:图3所示的步骤S301中,无线网络控制器203在向终端201发送第三指示信息时,发送的是上述信息2或者信息4。
这里,以终端发送接入前导时使用的物理资源为接入签名为例,无线网络控制器203向终端201发送接入签名组:group1、group2,……,groupP,其中P为正整数。其中group1中的接入签名对应一次随机接入过程中终端发送2个TTI的数据,group2中的接入签名对应一次随机接入过程中终端发送3个TTI,依次类推,groupP中的接入签名对应一次随机接入过程中终端发送P+1个TTI。
终端201收到该接入签名组后,根据自身的缓存数据量,以及一个TTI可以发送的数据包的大小,确定需要Q个TTI能够将数据发送完成,其中Q为正整数,且Q不大于P。则UE选择group Q-1中的接入签名,并用选择的接入签名生成preamble进行随机接入。
基站202检测到终端201发送的该接入签名后,根据上述对应关系,确定终端201需要发送的TTI的数目,并在该段时间内保证终端201发送该多个TTI使用的数据传输码道不分配给其他终端。
【方式二】
终端201通过专用物理控制信道(Dedicated Physical Control CHannel,DPCCH)发送第一指示信息。
【方式三】
终端201在发送接入前导时,向基站202发送第一指示信息,指示终端201要在本次随机接入过程中传输多个TTI的数据,并通过DPCCH发送第二指示信息,该第二指示信息用于指示:
该多个TTI具体为X个TTI,X为正整数;或
终端在本次随机接入过程中,当前TTI之后还有对应于另一个TTI的数据要传输;或
终端在本次随机接入过程中,当前TTI为数据传输的最后一个TTI。
通过方式三,终端201可通过第一指示信息指示基站,终端201要传输多个TTI,或者指示终端201要传输的多个TTI的TTI的数目,但由于可用的信息比特有限,因此即使指示要传输的多个TTI的TTI数目,可选择的值也只能为几个固定的值,无法达到精确指示;通过发送第二指示信息,可在终端201向基站传输多个TTI的数据的过程中,向基站202精确指示传输多少个TTI,而且占用较少的信息比特,这样,可保证基站202尽快释放终端201在传输数据时使用的资源,提高资源的利用率。
【方式四】
第一指示信息包括第一子信息和第二子信息;此时,第一指示信息还用于指示:该多个TTI具体为X个TTI。
其中,第一子信息用于指示终端201在本次随机接入过程中向基站202传输的多个数据包,可选地,还可具体指示传输的数据包的数目M;
第二子信息用于指示:终端201在本次随机接入过程中发送的每个数据包重复传输的次数N;
其中,M*N=X,M、N为正整数。
可选地,第二子信息还用于指示:终端201在本次随机接入过程中发送的当前数据包的重复传输是否结束。
终端201可通过DPCCH发送第一子信息和第二子信息。
比如,如图5A~5E所示,终端201通过第一个信息字段发送第一子信息, 通过第二个信息字段发送第二子信息。
图5A中,终端201通过第一个信息字段指示基站202,终端201要发送3个数据包;通过第二个字段指示基站202,本次传输的是第一个数据包的第一次;
图5B中,终端201通过第一个信息字段指示基站202,后续还有数据包发送;通过第二个字段指示基站202,本次传输的是当前传输的数据包的第一次;
图5C中,终端201通过第一个信息字段指示基站202,终端201本次传输的是最后一个数据包;通过第二个字段指示基站202,本次传输的是第三个数据包的第一次;
图5D中,终端201通过第一个信息字段指示基站202,终端201本次传输的是最后一个数据包;通过第二个字段指示基站202,该数据包要重复传输两次;
图5E中,终端201通过第一个信息字段指示基站202,终端201要发送的是第二个数据包;通过第二个字段指示基站202,本次传输的是第二个数据包的第一次。
终端201在向基站202发送接入前导时发送第一子信息,以及在传输多个TTI的数据时向基站202发送第二子信息;或
终端201在向基站202发送接入前导时发送第二子信息,以及在传输多个TTI的数据时向基站202发送第一子信息。
可选地,若方式四中,终端201在向基站202发送接入前导时发送第一子信息,则第一子信息还包括:终端201发送接入前导时使用的物理资源的信息;
若终端201在向基站202发送接入前导时发送第二子信息,则第二子信息还包括:终端201发送接入前导时使用的物理资源的信息。
可选地,若终端201在向基站202传输多个TTI的数据时发送第二子信息,则第二子信息通过DPCCH发送;
若终端201在向基站202传输多个TTI的数据时发送第一子信息,则第一子信息通过DPCCH发送。
可选的实现方式不限于上述四种方式,只要能够指示基站202,终端201在一次随机接入过程中传输多个TTI的数据即可。
下面,以WCDMA制式为例,说明上述方式二、方式三和方式四中,终端201通过DPCCH发送指示信息的方法。
如图4所示,现有的WCDMA系统中,随机接入过程中,当终端发送的无线帧的消息部分长度为TRACH=10ms时,其中包括时隙#0、时隙#1,……,时隙#i,……至时隙#14。对于每一个时隙,终端同时发送数据部分和控制部分,其中数据部分包括Ndata比特,控制部分包括Npilot比特的导频和NTFCI比特的发送格式组合指示(Transmit Format Combined Indicator,TFCI)。
本发明实施例中,一种可选的实现方式是:终端201通过图4中的数据部分传输多个TTI的数据,利用和数据部分同时发送的导频和/或TFCI中的若干比特传输指示信息。由于导频和TFCI是重复多次发送的,因此占用导频和/或TFCI中的若干次的发送不会导致无法发送导频和TFCI,仅会对导频和TFCI的接收性能有一定的影响。
图4中,控制部分是通过DPCCH传输的,所以本发明实施例中的指示信息可通过DPCCH传输。
或者,终端201还可采用下述方式,通过DPCCH发送第一指示信息:
采用用于传输导频序列的2比特传输该指示信息,此时DPCCH可包括6比特的导频序列、2比特的传输格式组合指示及2比特的第一指示信息。由于2比特最大可指示最大传输4个TTI的数据,因此,可通过该PRACH的15个时隙中每个时隙的控制部分选择2比特携带该第一指示信息,继而将该15个时隙各自的2比特进行联合以携带该第一指示信息,从而可以指示更多的TTI的数据传输。
对于上述方式一和方式三,终端201在向基站202发送接入前导时发送第一指示信息,第一指示信息还包括:终端发送接入前导时使用的物理资源 的信息,指示基站202根据第一对应关系确定终端201在本次随机接入过程中传输X个TTI的数据;
其中,第一对应关系包括:终端发送接入前导时使用的物理资源的信息与X的对应关系。
可选地,该第一对应关系的信息,是无线网络控制器203在终端201向基站202发送第一指示信息之前发送给终端201的。
可选地,无线网络控制器203还将第一对应关系的信息发给基站202,基站202将该信息保存,待终端201发送接入前导时,根据预存的该第一对应关系,确定终端201在一次随机接入过程中传输的TTI的数目。
类似地,对于上述方式四,若终端201在向基站202发送接入前导时发送第一子信息,则第一子信息还用于:指示基站202根据第二对应关系,确定在本次随机接入过程中终端201向基站202传输M个数据包,第二对应关系包括:终端发送接入前导时使用的物理资源的信息与终端在一次随机接入过程中向基站传输的数据包的数目的对应关系。
可选地,第二对应关系的信息,是无线网络控制器203在终端201向基站202发送第一指示信息之前发送给终端201的。
可选地,无线网络控制器203还将第二对应关系的信息发给基站202,基站202将该信息保存,待终端201发送接入前导时,根据预存的第二对应关系,确定终端201在一次随机接入过程中传输的数据包的数目。
若终端201在向基站202发送接入前导时发送第二子信息,则第二子信息还用于:指示基站202根据第三对应关系,确定在本次随机接入过程中终端201向基站202传输的每个数据包重复传输N次,第三对应关系包括:终端发送接入前导时使用的物理资源的信息与终端在一次随机接入过程中终端向基站传输的每个数据包重复传输的次数的对应关系。
可选地,第三对应关系的信息,是无线网络控制器203在终端201向基站202发送第一指示信息之前发送给终端201的。
可选地,无线网络控制器203还将第三对应关系的信息发给基站202,基 站202将该信息保存,待终端201发送接入前导时,根据预存的第三对应关系,确定终端201在一次随机接入过程中传输的每个数据包重复传输的次数。
以上介绍了图3所示的随机接入过程中终端传输多个TTI的数据的一种可选方案。下面,介绍另一种方案,该方案中,无需终端向基站发送指示信息,指示终端要传输多个TTI的数据,而是基站自身判断终端是否传输多个TTI的数据。
终端在确定需要发送多个TTI的数据时,在获得的随机接入资源上进行数据包的传输;作为接收端,基站在通过AICH发送确认指示(ACKnowledgement,ACK)之后,在预设的时长内检测终端是否继续发送数据。若终端在该预设的时长内没有检测到终端在其使用的随机接入资源上发送了数据包,则基站确定终端的连续数据传输结束,该随机接入资源可分配给其他终端使用。可选地,该预设的时长可能为1个TTI。
以上,介绍了本发明实施例提供的无线通信系统。基于相同的发明构思,本发明实施例还提供了终端、基站和无线网络控制器,以及随机接入过程中的数据传输方法和指示信息的发送方法。由于其解决技术问题的原理与本发明实施例提供的无线通信系统类似,其实施可参照该系统的实施,重复之处不再赘述。

进一步,终端可在向基站发送上述第一指示信息之前,接收无线网络控制器(Radio Network Controller,RNC)发送的第三指示信息,该第三指示信息用于指示允许所述终端在本次随机接入过程中传输多个TTI的数据,终端收到该第三指示信息后,确定需要在本次随机接入过程中向基站传输多个TTI的数据时,向基站发送上述第一指示信息。
