具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图 时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的切换参数处理方法可应用于图1所示的无线通信系统中。参照图1所示,该无线通信系统100包括网络设备110和终端120。网络设备110和终端120之间通过无线资源进行信息的发送与接收。
可以理解的是,图1所示的无线通信系统仅是进行示意性说明。无线通信系统中还可包括其它网络设备,例如还可以包括核心网设备、无线中继设备和无线回传设备等,在图1中未画出。本公开实施例对该无线通信系统包括的网络设备数量和终端数量不做限定。
进一步可以理解的是,本公开实施例无线通信系统,是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术,例如码分多址(Code Division Multiple Access,CDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency-Division Multiple Access,OFDMA)、单载波频分多址(Single Carrier FDMA,SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance,CSMA/CA)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(Generation)网络、3G网络、4G网络或者未来的任一代演进网络中,如5G网络和后续的任一代网络,5G网络也可称为是5G新空口。为了方便描述,本公开有时会将无线通信网络简称为网络。
进一步的,本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是:基站、演进型基站(evolved NodeB,eNodeB或者eNB)、家庭基站、无线保真(Wireless Fidelity,WIFI)系统中的接入点(Access Point,AP)、无线中继节点、无线回传节点、传输点(Transmission Point,TP)或者发送接收点(Transmission and Reception Point,TRP)等,还可以为NR系统中的基站(gNodeB或者gNB),或者,还可以是构成基站的组件或一部分设备等。应理解,本公开实施例中,对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中,网络设备可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域(小区)内的终端进行通信。此外,当为车联网(V2X)通信系统时,网络设备还可以是车载设备。
进一步的,本公开中涉及的终端,也可以称为终端设备、用户设备(User Equipment,UE)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal,MT)等,是一种向用户提供语音和/或数据连通性的设备。例如,终端可以是具有无线连接功能的手持式设备、 车载设备等。目前,一些终端的示例为:智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer,PPC)、掌上电脑、个人数字助理(Personal Digital Assistant,PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外,当为车联网(V2X)通信系统时,终端设备还可以是车载设备。应理解,本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
5G NR引入了NTN。NTN是指5G卫星通信网,其具有小区半径大的特点。对于低轨(Low Earth Orbit,LEO)卫星和中轨(Medium Earth Orbit,MEO)卫星,其小区覆盖半径可以为100km-1000km。对于同步轨道/静止轨道(Geosynchronous Earth Orbit,GEO)卫星,其小区覆盖半径可以到几千米。因此,NTN中的一个小区可能服务大量的用户。然而,由于卫星的移动,用户不可避免的需要进行切换。在一段时间内,大量的用户需要同时切换,如表1所示。当前C-RNTI(Cell-Radio Network Temporary Identifier,小区无线网络临时标识)支持的连接用户数量的最大值为65519。假设一个小区有65519个用户,下述表1列出了不同小区大小时的平均切换率。
表1:
Figure PCTCN2020107133-appb-000001
在TN(Terrestrial Networks,陆地网络)中,当UE进行切换时,切换命令由源小区通过RRC信令配置给UE,切换命令中包括唯一目标小区的一些配置。如果NTN采用同样的切换方法,则由于短时间内需要切换大量用户,会导致大量的信令开销并对业务连续性也提出了挑战。
发明人注意到,由于卫星的路径相对固定并且在不同方向的邻小区数量少,因此考虑在切换参数中包括至少一个目标小区的切换参数配置,并且可以将上述配置预配置给UE,所述预配置是指在UE切换之前就将切换参数配置给UE。通过在切换参数中包括至少一组切换参数,并且至少一组切换参数中的每一组切换参数分别对应于至少一个目标小区中的一个目标小区,使得切换参数可以预配置给UE。这避免了短时间内大量的切换命令产生,避免大量信令开销,并且保证了业务连续性。
本公开实施例提供一种切换参数处理方法,其应用于网络设备。图2是根据一示例性实施例示出的一种切换参数处理方法的流程图。参照图2所示,切换参数处理方法应用于 网络设备,包括如下步骤S210。
在步骤S210中,确定切换参数集,其中所述切换参数集至少包括至少一组切换参数,所述至少一组切换参数中的每一组切换参数分别对应于至少一个目标小区中的一个目标小区。
在本公开的一些实施例中,该切换参数集至少包括一组切换参数。在本公开的另一些实施例中,该切换参数集至少包括多组切换参数;其中,多组切换参数是指两组或两组以上切换参数。
根据本公开实施例,由于切换参数包括至少一组切换参数,并且至少一组切换参数中的每一组切换参数分别对应于至少一个目标小区中的一个目标小区,使得切换参数可以预配置给UE。这避免了短时间内大量的切换命令产生,避免大量信令开销,并且保证了业务连续性。
在本公开的一些实施例中,切换参数集包括对应于所有目标小区的切换参数。可替换实施例中,切换参数集包括对应于部分目标小区的切换参数。在本公开上下文中,例如,目标小区是指UE的服务小区的邻小区,并且所有邻小区都可能是UE的目标小区。
在本公开的一些实施例中,针对当前小区内的所有UE可以应用相同的切换参数集,也可以针对不同UE应用不同的切换参数集。在本公开的一些实施例中,针对当前小区内的所有UE可以应用同一个切换参数集中的相同的切换参数;即针对每一个UE,同一个目标小区都采用相同的切换参数。在本公开的一些实施例中,针对当前小区内的所有UE可以应用同一个切换参数集中的不同的切换参数;即针对每一个UE,同一个目标小区可以对应不同的切换参数。
在本公开实施例中,切换参数集可以通过以下的任意一种方式确定和/或更新:
切换参数集,可以是由网络侧设备发送给UE的;可以是网络侧设备将至少一套切换参数集的参数值都发送给UE;也可以是网络侧设备从候选的多套切换参数集中确定出至少一套切换参数集,然后将这至少一套切换参数集对应的标识符发送给UE,以使UE从相应的多套切换参数集中确定出至少一套切换参数集;还可以是网络侧设备从候选的多个切换参数中确定出一个或多个切换参数,以形成一个或多个切换参数集,然后将这些切换参数对应的标识符发送给UE,以使UE从相应的切换参数中确定出一个或多个切换参数,以形成切换参数集。
切换参数集,可以是由通信协议中给出的多个候选切换参数集和/或多个切换参数中确定出的;例如,UE可以根据当前的参数确定出采用那些候选切换参数集和/或那些切换参数。在一些实施例中,参数可以为以下任一种:位置、小区ID、基站ID、信道状态。
切换参数集和/或切换参数,可以是由基站发送的两个或多个参数共同确定的。
切换参数集和/或切换参数,可以是预存储在基站和/或终端内的,以使终端能够根据当前的参数确定使用的切换参数集和/或切换参数。在本公开实施例中,不同的切换参数是指,该切换参数不完全相同或完全不相同。
接着描述根据本公开实施例的切换参数集中的切换参数的设置方式。
在本公开的一些实施例中,切换参数集中的至少一组切换参数包括用于标识目标小区的位置信息,以及目标小区对应的切换参数;或,切换参数集中的至少一组切换参数包括用于标识目标小区的标识信息,以及目标小区对应的切换参数;或,切换参数集中的每一组切换参数包括用于标识目标小区的类型信息,以及目标小区对应的切换参数。
在本公开的一些实施例中,目标小区的类型信息用于指示目标小区为地面小区或非地面小区。在本公开上下文中,例如,地面小区是指基于TN的小区,非地面小区是指基于NTN的小区。例如,非地面小区可以包括基于LEO的小区、基于MEO的小区、以及基于GEO的小区。
在示例性实施例中,切换参数集中的至少一组切换参数包括用于标识目标小区的位置信息,以及目标小区对应的切换参数。即,切换参数集中的至少一组切换参数包括与目标小区关联的位置信息,其中不同的位置信息对应不同的切换参数。这种情况下,作为示例,至少一组切换参数包括:位置信息1,切换参数1;位置信息2,切换参数2;…位置信息n,切换参数n,其中n为大于或等于2的自然数,并且切换参数n是用于与位置信息n对应的目标小区的切换参数。
在示例性实施例中,切换参数集中的至少一组切换参数包括用于标识目标小区的标识信息,以及目标小区对应的切换参数。即,切换参数集中的至少一组切换参数包括与目标小区关联的标识(Identity,ID)信息,其中不同的ID信息对应不同的切换参数。这种情况下,作为示例,至少一组切换参数包括:小区ID 1,切换参数1;小区ID 2,切换参数2;…小区ID n,切换参数n,其中n为大于或等于2的自然数,并且切换参数n是用于与小区ID n对应的目标小区的切换参数。
在示例性实施例中,切换参数集中的每一组切换参数包括用于标识目标小区的类型信息,以及目标小区对应的切换参数。即,切换参数集中的至少一组切换参数包括与目标小区关联的网络类型信息,其中不同的网络类型信息对应不同的切换参数。这种情况下,作为示例,至少一组切换参数包括:网络类型信息1,切换参数1;网络类型信息2,切换参数2;…网络类型信息n,切换参数n,其中n为大于或等于2的自然数,并且切换参数n是用于与网络类型信息n对应的目标小区的切换参数。
作为示例,至少一组切换参数包括:TN,切换参数1;LEO,切换参数2;MEO,切换参数3;GEO,切换参数4。例如,每一组切换参数包括定时器T304。在切换过程中,UE在收到切换的重配置消息之后,会启动定时器T304。如果UE在定时器T304超时之前无法完成在目标小区的随机接入,则会发起原因值为切换失败(Handover Failure)的重建。对于不同的网络类型,其传输时延不相同,因此设置不同的定时器T304时长。例如,在上述对于TN、LEO、MEO、GEO的切换参数1、切换参数2、切换参数3、切换参数4,其各自包括的定时器T304的时长按照依次递增的方式设置。
接着描述根据本公开实施例的切换参数集的发送方式。
在本公开的一些实施例中,切换参数处理方法包括下述的至少一种:通过随机接入过程通过MSG4或MSGB消息发送切换参数集;通过无线资源控制RRC信令的重配置消息发送切换参数集;通过系统消息发送切换参数集。
在第一种发送方式中,在随机接入过程中,通过MSG4或MSGB将切换参数集发送给UE。
在第二种发送方式中,在RRC重配置消息中将切换参数集发送给UE。
在第三种发送方式中,系统消息通过广播将切换参数集发送给UE,通过这种发送的切换参数集只包括目标小区对UE共有的切换参数。
在其它发送方式中,可以将如上所述的发送方式相互结合。例如,第一种发送方式和第二种发送方式结合,在随机接入过程中先配置一部分切换参数,并且在RRC重配置信息中再配置一部分切换参数。又例如,第一种发送方式和第三种发送方式结合,在随机接入过程中先配置一部分切换参数,并且系统消息通过广播将目标小区对UE共有的切换参数发送给UE。又例如,第二种发送方式和第三种发送方式结合,在RRC重配置信息中配置一部分切换参数,并且系统消息通过广播将目标小区对UE共有的切换参数发送给UE。
接着描述在随机接入过程中通过MSG4或MSGB发送切换参数。
随机接入过程是指从终端发送随机接入前导序列(Preamble)开始尝试接入网络到与网络间建立起基本的信令连接之前的过程,其用于使终端与网络建立数据通信。目前大多数终端采用基于竞争的随机接入过程。这种随机接入过程包括4步随机接入过程和2步随机接入过程。
在4步随机接入过程中,每一步为一条消息(MSG,Message),并且在标准中这4步称为MSG1-MSG4。例如,该4步随机接入过程包括下述第1-4步。第1步,终端向接入网设备发送MSG1。该MSG1包括随机接入前导序列。基于竞争的随机接入可用的随机接入前导序列以及用于发送随机接入前导序列的物理随机接入信道(PRACH,Physical  Random Access Channel)资源由接入网设备进行配置,并通过系统消息将配置结果通知到小区内的终端。第2步,接入网设备向终端发送MSG2。该MSG2包括随机接入响应(Random Access Response,RAR)。终端通过检测MSG2中是否携带了其所发送的Preamble序列的标识来判断是否收到随机接入响应。MSG2可以包括与MSG1对应的随机接入前导序列的标识、上行传输定时提前量、为终端分配的上行资源、临时C-RNTI等参数。第3步,终端向接入网设备发送MSG3。终端正确接收MSG2后,在MSG2中分配的上行资源中传输MSG3,完成第一次调度传输。MSG3中可以包括终端的身份标识信息,例如C-RNTI标识或者临时C-RNTI标识。第4步,接入网设备向终端发送MSG4。接入网设备和终端通过MSG4完成最终的竞争解决。MSG4的内容和MSG3的内容相对应。
2步随机接入过程可以如上所述的4步随机接入过程合并而成。在基于竞争的2步随机接入过程包括下述第1-2步。第1步,终端向接入网设备发送MSGA,接站接收MSGA。MSGA包括随机接入前导序列和物理上行共享信道(Physical Uplink Shared Channel,PUSCH)数据。PUSCH数据可以包含终端的身份标识信息,例如C-RNTI等。即,MSGA包括MSG1和MSG3二者的内容。第2步,接入网设备向终端发送MSGB,终端接收MSGB。MSGB包括:随机接入响应和竞争解决信息。即,MSGB包括MSG2和MSG4二者的内容。
在本公开的一些实施例中,可以如上所述在随机接入过程中通过MSG4或MSGB发送切换参数。尽管在上述示例性实施例中以MSG4或MSGB作为在随机接入过程中将切换参数集发送给UE的方式予以描述,但是本公开实施例不限于此。为了在随机接入过程中发送切换参数,可以采用任何适当格式的消息,该格式的消息可以是目前已知的类型的格式,例如基于MSG4或MSGB提出的改进类型的消息,也可以是未来发展的用于在随机接入过程中使终端与网络建立数据通信的其它格式。
接着描述根据本公开实施例的切换参数集的一些示例性发送方式。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB发送切换参数集,切换参数集包括切换所需要的全部切换参数。
在本公开的一些实施例中,通过无线资源控制RRC信令的重配置消息发送切换参数集,切换参数集包括切换所需要的全部切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB发送切换所需要的切换参数集的第一部分,其中切换参数集的第一部分包括一组或多组切换参数;以及通过无线资源控制RRC信令的重配置消息发送包括切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括的一组或多组切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB发送切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及通过无线资源控制RRC信令的重配置消息发送包括切换所需要的切换参数集的第一部分,其中切换参数集的第一部分包括的一组或多组切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB发送切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及通过系统消息发送切换所需要的切换参数的第一部分,其中切换参数集的第一部分包括一组或多组切换参数。
在本公开的一些实施例中,通过无线资源控制RRC信令的重配置消息发送切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及通过系统消息发送切换所需要的切换参数的第一部分,其中切换参数集的第一部分包括一组或多组切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB发送切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;通过系统消息发送切换所需要的切换参数集的第一部分,其中切换参数集的第一部分包括一组或多组切换参数;以及通过无线资源控制RRC信令的重配置消息发送切换到目标小区的切换指示。
在本公开的一些实施例中,切换所需要的全部切换参数由切换参数集的第一部分和切换参数集的第二部分一起构成。例如,切换参数集的第一部分包括适用于所有终端的相同的切换参数。例如,切换参数集的第二部分包括终端在至少一个目标小区中的特定的切换参数。
结合具体实例描述如上所述的根据本公开实施例的切换参数集的发送方式。
在第一实例中,在随机接入过程中,网络通过MSG4将至少一组切换参数发送给UE,其中至少一组切换参数只包括UE所需要的部分参数,例如对所有UE都相同的切换参数:spCellConfigCommon、T304;以及在RRC重配消息中包括UE拟切换的目标小区的对UE特定的切换参数,例如UE在目标小区的标识。
在第二实例中,在系统消息中包括至少一组切换参数,并通过系统消息发送给UE,其中切换参数只包括UE所需要的部分参数,例如对所有UE都相同的切换参数,spCellConfigCommon、T304;以及在RRC重配消息中包括UE拟切换的目标小区的对UE特定的切换参数,例如UE在目标小区的标识。
在第三实例中,在随机接入过程中,网络通过MSG4或MSGB将至少一组切换参数 发送给UE,其中至少一组切换参数包括UE所需要的全部参数。
在第四实例中,在发送给UE的RRC重配消息中包括至少一组切换参数,其中切换参数包括UE所需要的全部参数。
在第五实例中,在随机接入过程中,网络通过MSG4或MSGB将至少一组切换参数发送给UE,至少一组切换参数只包括目标小区的对UE特定的切换参数,例如UE在目标小区的标识;在系统消息中包括至少一组切换参数,并通过系统消息发送给UE,其中至少一组切换参数只包括对所有UE都相同的切换参数,例如spCellConfigCommon、T304;以及在发送给UE的RRC重配消息中只包括指示UE切换到目标小区的切换指示。
接着描述根据本公开实施例的发送的切换参数存在冲突时的处置方式。
在本公开的一些实施例中,当切换参数集的第一部分与切换参数集的第二部分包括相同类型的切换参数时,通过无线资源控制RRC信令的重配置消息发送的相同类型的切换参数配置为用于切换。
在示例性实施例中,当通过RRC发送给UE的切换参数与通过系统消息广播给UE的切换参数冲突时,通过RRC发送给UE的切换参数配置为用于切换,即,UE以RRC发送的切换参数为准。例如,当RRC配置的目标小区ID 1对应的定时器T304为200ms,目标小区ID 2对应的定时器T304为300ms,而系统消息配置的目标小区ID 1对应的定时器T304为100ms,目标小区ID 2对应的定时器T304为200ms时,RRC配置的定时器T304用于切换,即,UE应用RRC配置的定时器T304,目标小区ID 1对应的定时器T304为200ms,目标小区ID 2对应的定时器T304为300ms。
需要说明的是,本领域技术人员可以理解,本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用,也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用,其实现原理类似。本公开实施中,部分实施例中是以一起使用的实施方式进行说明的;当然,本领域技术人员可以理解,这样的举例说明并非对本公开实施例的限定。
本公开实施例提供一种切换参数处理方法,应用于终端。图3是根据一示例性实施例示出的一种切换参数处理方法的流程图。参照图3所示,切换参数处理方法应用于终端,包括如下步骤S310。
在步骤S310中,获取切换参数集,其中所述切换参数集至少包括至少一组切换参数,所述至少一组切换参数中的每一组切换参数分别对应于至少一个目标小区中的一个目标小区。
根据本公开实施例,由于切换参数包括至少一组切换参数,并且至少一组切换参数中 的每一组切换参数分别对应于至少一个目标小区中的一个目标小区,使得切换参数可以预配置给UE。这避免了短时间内大量的切换命令产生,避免大量信令开销,并且保证了业务连续性。
在本公开的一些实施例中,切换参数集包括对应于所有目标小区的切换参数;或切换参数集包括对应于部分目标小区的切换参数。在本公开上下文中,例如,目标小区是指UE的服务小区的邻小区,并且所有邻小区都可能是UE的目标小区。
接着描述根据本公开实施例的切换参数集中的切换参数的设置方式。
在本公开的一些实施例中,切换参数集中的至少一组切换参数包括用于标识目标小区的位置信息,以及目标小区对应的切换参数;或,切换参数集中的至少一组切换参数包括用于标识目标小区的标识信息,以及目标小区对应的切换参数;或,切换参数集中的每一组切换参数包括用于标识目标小区的类型信息,以及目标小区对应的切换参数。
在本公开的一些实施例中,目标小区的类型信息用于指示目标小区为地面小区或非地面小区。在本公开上下文中,例如,地面小区是指基于TN的小区,非地面小区是指基于NTN的小区。例如,非地面小区可以包括基于LEO的小区、基于MEO的小区、以及基于GEO的小区。
在本公开的一些实施例中,根据终端的位置信息,确定切换参数集中与终端的位置信息匹配的用于标识目标小区的位置信息,以及目标小区对应的切换参数,并利用目标小区对应的切换参数进行切换。
在本公开的一些实施例中,根据目标小区的标识信息,确定切换参数集中与目标小区的标识信息匹配的用于标识目标小区的标识信息,以及目标小区对应的切换参数,并利用目标小区对应的切换参数进行切换。
在本公开的一些实施例中,根据目标小区的网络类型,确定切换参数集中与目标小区的网络类型匹配的用于标识目标小区的标识信息,以及目标小区对应的切换参数,并利用目标小区对应的切换参数进行切换。
在示例性实施例中,切换参数集中的至少一组切换参数包括用于标识目标小区的位置信息,以及目标小区对应的切换参数。例如,当UE需要切换时,根据所处的位置信息与网络发送位置信息进行匹配,确定应用目标切换参数。在示例性实施例中,UE在随机接入过程中接收到网络通过MSG4配置的至少一组切换参数:位置信息1,切换参数1;位置信息2,切换参数2。UE收到网络发送的切换命令,并且根据其位置信息确定目标小区的切换参数,如果UE位置在位置信息2内,则应用切换参数2。
在示例性实施例中,切换参数集中的至少一组切换参数包括用于标识目标小区的标识 信息,以及目标小区对应的切换参数。例如,当UE需要切换时,根据目标小区的ID确定切换参数。在示例性实施例中,UE接收系统消息广播的至少一组切换参数:小区ID 1,切换参数1;小区ID 2,切换参数2。UE收到网络发送的切换命令,并且根据目标小区的ID确定切换参数,如果目标小区ID为ID 1,则应用切换参数1。
在示例性实施例中,切换参数集中的每一组切换参数包括用于标识目标小区的类型信息,以及目标小区对应的切换参数。例如,当UE需要切换时,根据目标小区的网络类型确定切换参数。在示例性实施例中,UE在随机接入过程中接收到网络通过MSG4配置的至少一组切换参数:网络类型1,切换参数1(T304);网络类型2,切换参数2(T304)。UE接收系统消息广播的至少一组切换参数:小区ID 1,切换参数1;小区ID 2,切换参数2,其中切换参数1和切换参数2不包含定时器T304。UE收到网络发送的RRC重配消息,如果RRC重配消息包括切换目标小区UE对UE特定的配置,例如UE标识,则UE根据目标小区的类型,目标小区的ID确定切换目标小区的切换参数。
接着描述根据本公开实施例的切换参数集的接收方式。
在本公开的一些实施例中,切换参数处理方法包括下述的至少一种:通过随机接入过程通过MSG4或MSGB消息接收切换参数集;或通过无线资源控制RRC信令的重配置消息接收切换参数集;或通过系统消息接收切换参数集。
在第一种接收方式中,在随机接入过程中,UE通过MSG4或MSGB接收切换参数集。
在第二种接收方式中,UE在RRC重配置消息中接收切换参数集。
在第三种接收方式中,UE接收系统消息广播的切换参数集,通过这种接收的切换参数集只包括目标小区对UE共有的切换参数。
在其它接收方式中,可以将如上所述的接收方式相互结合。例如,第一种接收方式和第二种接收方式结合,在随机接入过程中先接收一部分切换参数,并且在RRC重配置信息中再接收一部分切换参数。又例如,第一种接收方式和第三种接收方式结合,在随机接入过程中先接收一部分切换参数,并且UE接收系统消息中通过发送的目标小区对UE共有的切换参数。又例如,第二种接收方式和第三种接收方式结合,在RRC重配置信息中接收一部分切换参数,并且UE接收系统消息广播的目标小区对UE共有的切换参数。
接着描述根据本公开实施例的切换参数集的一些示例性接收方式。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB接收切换参数集,切换参数集包括切换所需要的全部切换参数。
在本公开的一些实施例中,通过无线资源控制RRC信令的重配置消息接收切换参数集,切换参数集包括切换所需要的全部切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB接收切换所需要的切换参数集的第一部分,其中切换参数集的第一部分包括一组或多组切换参数;以及通过无线资源控制RRC信令的重配置消息接收包括切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括的一组或多组切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB接收切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及通过无线资源控制RRC信令的重配置消息接收包括切换所需要的切换参数集的第一部分,其中切换参数集的第一部分包括的一组或多组切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB接收切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及接收系统消息广播的切换所需要的切换参数的第一部分,其中切换参数集的第一部分包括一组或多组切换参数。
在本公开的一些实施例中,通过无线资源控制RRC信令的重配置消息接收切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及接收系统消息广播的切换所需要的切换参数的第一部分,其中切换参数集的第一部分包括一组或多组切换参数。
在本公开的一些实施例中,在随机接入过程中通过MSG4或MSGB接收切换所需要的切换参数集的第二部分,其中切换参数集的第二部分包括一组或多组切换参数;以及接收系统消息广播的切换所需要的切换参数的第一部分,其中切换参数集的第一部分包括一组或多组切换参数;以及通过无线资源控制RRC信令的重配置消息接收切换到目标小区的切换指示。
在本公开的一些实施例中,切换所需要的全部切换参数由切换参数集的第一部分和切换参数集的第二部分一起构成。例如,所述切换参数集的第一部分包括适用于所有终端的相同的切换参数。例如,所述切换参数集的第二部分包括终端在至少一个目标小区中的特定的切换参数。
在本公开的一些实施例中,当切换参数集的第一部分与切换参数集的第二部分包括相同类型的切换参数时,通过无线资源控制RRC信令的重配置消息接收的相同类型的切换参数配置为用于切换。
在示例性实施例中,当UE通过RRC接收的切换参数与通过接收系统消息广播得到的切换参数冲突时,UE通过RRC接收的切换参数配置为用于切换,即,UE以RRC发送的切换参数为准。例如,当RRC配置的目标小区ID 1对应的定时器T304为200ms,目标小 区ID 2对应的定时器T304为300ms,而系统消息配置的目标小区ID 1对应的定时器T304为100ms,目标小区ID 2对应的定时器T304为200ms时,RRC配置的定时器T304用于切换,即,UE应用RRC配置的定时器T304,目标小区ID 1对应的定时器T304为200ms,目标小区ID 2对应的定时器T304为300ms。
