Description

一种随机接入的方法、终端及基站 技术领域
本发明涉及无线通信领域,尤其涉及一种随机接入的方法、终端及基站。
背景技术
在无线通信系统中,存在随机接入资源,供终端(User Equipment,UE)有突发上行业务随机接入网络时使用。其中,UE与网络建立连接的过程被称为随机接入过程。
目前,多数系统采用系统广播配置随机接入资源。然而,系统广播一旦配置随机接入资源之后,如果需要变更配置,就需要等待变更周期,因此变更起来相对较慢,是一种类似“半静态”的配置方法;同时,由于系统广播配置一旦发生变化,需要通知所有的UE,代价很高。因此,在一些设备到设备(Machine to Machine,简称:M2M)通信系统中,若出现火灾、地震等紧急情况,需要网络快速变更随机接入资源的配置时,很容易导致网络拥塞。如果配置过多的上行资源供随机接入使用,由于这部分资源在相当长一段时间内无法供UE发送上行数据使用,又会造成极大的浪费。
因此,如何灵活配置随机接入资源,成为目前亟待解决的技术问题。

实施例一、
本发明实施例提供一种随机接入的方法,如图1所示,包括:
S101、UE接收基站通知的随机接入资源的配置信息,所述随机接入资源的配置信息包括:基站通过系统广播通知的第一随机接入资源的配置信息、以及基站通过下行控制信息(Downlink Control Information,简称:DCI)通知的第二随机接入资源的配置信息。

S103、UE根据所述随机接入资源发起随机接入。
具体的,本发明实施例提供的随机接入方法中,UE可以根据随机接入规则、基站通过系统广播通知的第一随机接入资源的配置信 息、以及基站通过DCI通知的第二随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源后发起随机接入,该随机接入规则可以是预先配置在UE中的,也可能是基站发送给UE的,比如,通过第一随机接入资源的配置信息携带该随机接入规则;或者通过系统广播通知该随机接入规则,本发明实施例对此不作具体限定。
其中,该随机接入规则可以包括下述规则中的至少一种规则:
随机选择随机接入资源;
根据预发送的业务的类型选择随机接入资源;
选择与UE的时频资源最近邻的随机接入资源;
根据UE的类型,选择随机接入资源;
以及,根据UE的接入原因,选择随机接入资源。
需要说明的是,本发明实施例中的随机接入规则可以是一种规则,也可以是多种规则的组合,例如随机接入规则可以包括:根据预发送的业务的类型以及UE的类型选择随机接入资源;或者,根据预发送的业务的类型以及UE的接入原因选择随机接入资源等,本发明实施例对此不作具体限定。
可以理解的是,本发明实施例中的随机接入规则还可以为其它规则,并不限于上述列举的具体的随机接入规则,本发明实施例对此不作具体限定。
进一步的,本发明实施例中,随机接入规则不同,则选择随机接入资源的方式不同。下面提供几种可能的根据随机接入规则选择随机接入资源的方式如下:
方式一:
一种可能的实现方式中,若所述随机接入规则包括随机选择随机接入资源,则所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,具体可以包括:
所述UE生成随机数;
所述UE根据所述随机数、概率因子、以及所述基站通知的随机接入资源的配置信息,从所述第一随机接入资源和所述第二随机接入资源中选择随机接入资源。
具体的,该概率因子可以是根据系统广播的通知获得的,也可以是预先配置在UE中的,本发明实施例对此不作具体限定。
其中,所述UE根据所述随机数、概率因子、以及所述基站通知的随机接入资源的配置信息,从所述第一随机接入资源和所述第二随机接入资源中选择随机接入资源,具体可以包括:
若所述随机数大于所述概率因子,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源;
若所述随机数不大于所述概率因子,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源;
或者,
所述UE根据所述随机数、概率因子、以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,包括:
若所述随机数大于所述概率因子,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源;
若所述随机数不大于所述概率因子,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源。
具体的,该实现方式中,UE随机选择随机接入资源。例如,UE可以生成随机数,若所述随机数大于所述概率因子,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源;若所述随机数不大于所述概率因子,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源。示例性的,假设概率因子为0.5,UE生成的随机数为0.8,则由于0.8>0.5,此时UE根据随机接入规则,选择监听DCI,即,UE选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源。假设概率因子为0.9,UE生成的随机数为0.8,则由于0.9>0.8, 此时UE根据随机接入规则,选择基站通过系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源。
方式二、
一种可能的实现方式中,若所述随机接入规则包括根据预发送的业务的类型选择随机接入资源,则所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,包括:
若所述预发送的业务为周期型业务,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源;
若所述预发送的业务为突发型业务,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源;
或者,
所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,包括:
若所述预发送的业务对时延有要求,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源;
若所述预发送的业务对所述时延没有要求,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源。
具体的,该实现方式中,UE根据预发送的业务的类型选择随机接入资源。例如,通常突发型业务需要快速变更随机接入资源的配置,并且可能需要更多的上行数据资源,考虑到基站发送DCI的频率相对于基站发送系统广播的频率更加频繁,能够分配更多的空闲的上行资源供随机接入使用,因此UE可以选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源发起随机接入;而周期型业务相对固定,因此为了减少UE的等待时间,UE可以不用监听DCI,直接选择基站通过系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源发起随机接入。
或者,通常对时延有要求的业务需要在时延较小的情况下快速 接入网络,考虑到基站通过系统广播通知的第一随机接入资源的配置信息相对固定,UE可以不用等待,直接根据该配置信息对应的第一随机接入资源发起随机接入,因此UE可以选择基站通过系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源发起随机接入;否则,对于对时延没有要求的业务,UE可以选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源发起随机接入。通过上述示例可知,由于UE可以根据随机接入规则,选择随机接入资源发起随机接入,因此避免了现有技术中无法灵活配置随机接入资源的问题,能够灵活接入资源,从而达到最优配置。
当然,预发送的业务的类型也可能为其它,比如高优先级业务和低优先级业务等。不同的业务类型下,UE选择的随机接入资源也可能不相同,本发明实施例对此不作具体限定。
方式三、
一种可能的实现方式中,若所述随机接入规则包括选择与UE的时频资源最近邻的随机接入资源,则所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,包括:
所述UE根据所述基站通知的随机接入资源的配置信息,从所述第一随机接入资源和所述第二随机接入资源中选择与所述UE的时频资源最近邻的随机接入资源。
具体的,该实现方式中,UE选择与所述UE的时频资源最近邻的随机接入资源。例如,假设UE接收基站通过系统广播通知的第一随机接入资源的配置信息、以及所述基站通过DCI通知的第二随机接入资源的配置信息之后,确定第一随机接入资源中与所述UE的时频资源最近的随机接入资源在第二随机接入资源中与所述UE的时频资源最近的随机接入资源之前,则UE选择第一随机接入资源发起随机接入;否则,若确定第一随机接入资源中与所述UE的时频资源最近的随机接入资源在第二随机接入资源中与所述UE的时频资源 最近的随机接入资源之后,则UE选择第二随机接入资源发起随机接入。
方式四、
一种可能的实现方式中,若所述随机接入规则包括根据所述UE的类型,选择所述随机接入资源,则所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,包括:
若所述UE的优先级为第一优先级,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源;
若所述UE的优先级为第二优先级,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源。
具体的,该实现方式中,UE根据UE的类型,选择随机接入资源。例如,第一优先级具体为低优先级,第二优先级具体为高优先级,随机接入规则具体为:低优先级的UE选择基站通过系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源,高优先级的UE选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源。则,若UE为高优先级的UE,可以根据随机接入规则,选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源发起随机接入。
当然,UE的类型也可能为其它,比如低移动性和高移动性等。不同的UE的类型下,UE选择的随机接入资源也可能不相同,本发明实施例对此不作具体限定。
方式五、
一种可能的实现方式中,若所述随机接入规则包括根据UE的接入原因,选择随机接入资源,则所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源,包括:
若所述UE的接入原因为紧急呼叫,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第一随机接入资源;
若所述UE的接入原因为普通呼叫,所述UE根据所述基站通知的随机接入资源的配置信息,选择所述第二随机接入资源。
具体的,该实现方式中,UE根据UE的接入原因,选择随机接入资源。例如,若UE的接入原因为紧急呼叫,也即需要在时延较小的情况下快速接入网络,考虑到基站通过系统广播通知的第一随机接入资源的配置信息相对固定,UE可以不用等待,直接根据该配置信息对应的第一随机接入资源发起随机接入,因此UE可以选择基站通过系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源发起随机接入;否则,UE的接入原因为普通呼叫,UE可以选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源发起随机接入。
当然,UE的接入原因还可能为其它,比如跟踪区更新(Tracking Area Update,简称:TAU)、信令接入、数据接入、覆盖等级变更接入、连接态接入、空闲态接入等,本发明实施例对此不作具体限定。
以长期演进(Long Term Evolution,简称:LTE)为例,UE的接入原因可以包括:紧急(emergency)接入、高优先级接入(high Priority Access)、终端终结(Mobile Terminating,简称:MT)接入、终端触发(Mobile Originating,简称:MO)信令接入、MO数据接入,时延不明的接入(delay Tolerant Access),其中MT接入实际上就是诸如paging消息的响应;而MO接入是指终端自己触发的接入。
不同的接入原因下,UE选择的随机接入资源也可以不相同。比如,连接态的UE优先采用DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源;而空闲态的UE可以优先使用系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源,本发明实施例对此不作具体限定。
如上所述,本发明实施例中的随机接入规则可以是固定的一种规则,也可以是多种规则的组合。因此,可以理解的是,本发明实施例中方式一至方式五提供的根据随机接入规则,以及所述基站通 知的随机接入资源的配置信息,选择随机接入资源的方式可以组合。
示例性的,假设随机接入规则可以包括:根据预发送的业务的类型以及UE的类型选择随机接入资源,所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源具体包括:
当预发送的业务为突发型业务,且UE的优先级为高优先级时,UE根据所述基站通知的随机接入资源的配置信息,选择第一随机接入资源;
当预发送的业务为突发型业务,且UE的优先级为低优先级时,UE根据所述基站通知的随机接入资源的配置信息,选择第二随机接入资源;
当预发送的业务为周期型业务,且UE的优先级为高优先级时,UE根据所述基站通知的随机接入资源的配置信息,选择第一随机接入资源;
当预发送的业务为周期型业务,且UE的优先级为低优先级时,UE根据所述基站通知的随机接入资源的配置信息,选择第二随机接入资源。
则,当在发生火灾等突发状况时,考虑到突发型业务可能需要快速变更随机接入资源的配置,并且可能需要更多的上行数据资源,同时,高优先级UE可以快速接入,因此可以配置高优先级UE选择基站通过系统广播通知的第一随机接入资源的配置信息对应的第一随机接入资源,低优先级UE选择基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源。这样,一方面,由于基站发送DCI的频率相对于基站发送系统广播的频率更加频繁,能够分配更多的空闲的上行资源供随机接入使用,因此可以实现随机接入资源的配置信息的快速变更,同时能够分配更多的随机接入资源,比如可以将所有未使用的上行资源都配置为随机接入资源;另一方面,由于基站通过系统广播通知的第一随机接入资源的配置信息相对固定,UE可以直接根据该配置信息对应的第一随机接入资源发起 随机接入,因此减少了UE的等待时间,可以实现快速接入。由于UE可以根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,选择随机接入资源发起随机接入,因此避免了现有技术中无法灵活配置随机接入资源的问题,能够提高随机接入资源配置的灵活性,从而达到最优配置。
可以理解的是,本发明实施例中,UE根据随机接入规则,选择随机接入资源还可以是其它的方式,并不限于上述提供的实现方式。
本发明实施例提供一种随机接入方法,包括:UE接收基站通知的随机接入资源的配置信息,所述随机接入资源的配置信息包括:基站通过系统广播通知的第一随机接入资源的配置信息、以及基站通过下行控制信息DCI通知的第二随机接入资源的配置信息;所述UE根据随机接入规则,以及所述基站通知的随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源;所述UE根据所述随机接入资源发起随机接入。基于本发明实施例提供的随机接入方法,本发明实施例中的UE可以根据随机接入规则、基站通过系统广播通知的第一随机接入资源的配置信息、以及基站通过DCI通知的第二随机接入资源的配置信息,从第一随机接入资源和第二随机接入资源中选择随机接入资源。考虑到基站发送DCI的频率相对于基站发送系统广播的频率更加频繁,并且能够分配更多的空闲的上行资源供随机接入使用,因此在出现火灾、地震等紧急情况,需要网络快速变更随机接入资源的配置、以及需要更多的上行数据资源时,UE可以根据基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源发起随机接入;而基站通过系统广播通知的第一随机接入资源的配置信息相对固定,UE可以直接根据该配置信息对应的第一随机接入资源发起随机接入,因此减少了UE的等待时间。即,UE可以根据随机接入规则,灵活选择随机接入资源发起随机接入,因此避免了现有技术中无法灵活配置随机接入资源的问题,能够提高随机接入资源配置的灵活性,从而达到最优配置。
实施例二、
本发明实施例提供一种随机接入的方法,具体如图2所示,包括:
S201、基站确定通过系统广播通知的第一随机接入资源的配置信息、以及通过DCI通知的第二随机接入资源的配置信息。
S202、基站通过系统广播向UE通知所述第一随机接入资源的配置信息,以及基站通过DCI向所述UE通知所述第二随机接入资源的配置信息。
具体的,本发明实施例中,基站在配置随机接入资源时,一部分的随机接入资源(第一随机接入资源)的配置信息通过系统广播通知给UE,一部分的随机接入资源(第二随机接入资源)的配置信息通过DCI通知给UE。其中,
通过系统广播通知的第一随机接入资源的配置信息相对固定,UE发起随机接入之前,可以不用监听DCI直接发起随机接入,减少了UE的等待时间;
而基站发送DCI的频率相对于基站发送系统广播的频率更加频繁,并且能够分配更多的空闲的上行资源供随机接入使用,因此通过DCI通知的第二随机接入资源的配置信息能够快速变更随机接入资源的配置,并且能够分配更多的空闲的上行资源供随机接入使用,而且编码调制方式也可以灵活调整。
需要说明的是,在基站通过系统广播向UE通知第一随机接入资源的配置信息、以及基站通过DCI向UE通知第二随机接入资源的配置信息之后,还可能根据UE发起随机接入时所占用的随机接入资源获得UE的相关信息,包括接入原因、UE类型等。这样,可以专门针对这些信息对后续调度采用不同的机制,如对短时延要求的UE进行优先调度等。本发明实施例对此不作具体限定。
需要说明的是,本发明实施例中,基站可以将全部空闲资源配置为随机接入资源。该情况下,基站需要首先与UE约定:UE自己选择没有被调度的上行资源来使用。此时,需要UE通过监听DCI, 发现已经被使用的上行资源,进而再使用未被占用的上行资源来进行随机接入。本发明实施例对该情况不作具体限定。
进一步的,所述第一随机接入资源的配置信息中还可以包含随机接入规则。
即,可以在第一随机接入资源的配置信息中增加相应比特位,用于填充随机接入规则。
可选的,基站还可以通过系统广播向所述UE通知随机接入规则。
即,基站可以在系统广播中增加相应比特位,用于填充随机接入规则。

随机选择随机接入资源;
根据预发送的业务的类型选择随机接入资源;
选择最近邻的随机接入资源;
根据所述UE的类型,选择随机接入资源;
以及,根据所述UE的接入原因,选择随机接入资源。
需要说明的是,本发明实施例中的随机接入规则可以是一种规则,也可以是多种规则的组合,例如随机接入规则可以包括:根据预发送的业务的类型以及UE的类型选择随机接入资源;或者,根据预发送的业务的类型以及UE的接入原因选择随机接入资源等,本发明实施例对此不作具体限定。
可以理解的是,本发明实施例中的随机接入规则还可以为其它规则,并不限于上述列举的具体的随机接入规则,本发明实施例对此不作具体限定。
基于本发明实施例提供的随机接入的方法,包括:基站确定通过系统广播通知的第一随机接入资源的配置信息、以及通过DCI通知的第二随机接入资源的配置信息;基站通过系统广播向UE通知所 述第一随机接入资源的配置信息,以及基站通过DCI向UE通知第二随机接入资源的配置信息,使得UE可以根据基站通过系统广播通知的第一随机接入资源的配置信息与基站通过DCI通知的第二随机接入资源的配置信息选择随机接入资源。考虑到基站发送DCI的频率相对于基站发送系统广播的频率更加频繁,并且能够分配更多的空闲的上行资源供随机接入使用,因此在出现火灾、地震等紧急情况,需要网络快速变更随机接入资源的配置、以及需要更多的上行数据资源时,UE可以根据基站通过DCI通知的第二随机接入资源的配置信息对应的第二随机接入资源发起随机接入;而基站通过系统广播通知的第一随机接入资源的配置信息相对固定,UE可以直接根据该配置信息对应的第一随机接入资源发起随机接入,因此减少了UE的等待时间。即,UE可以根据随机接入规则,灵活选择随机接入资源发起随机接入,因此避免了现有技术中无法灵活配置随机接入资源的问题,能够提高随机接入资源配置的灵活性,从而达到最优配置。
