具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,所描述的实施例不应视为对本发明的限制,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
在对本发明实施例提供的接入控制方法进行详细说明之前,先对DC和条件切换(conditional handover)进行简要说明。
DC
新无线(New Radio,NR)系统(也可以称为5G系统)的主要应用场景包括:增强移动超宽带(Enhanced Mobile Broadband,eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications,URLLC)、大规模机器类通信(massive Machine Type of Communication,mMTC)等实现高速率业务的场景。其中。eMBB以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化、电力自动化、远程医疗操作(手术)、交通安全保障等。mMTC的典型特点包括:高连接密度、小数据量、时延不敏感业务、模块的低成本和长使用寿命等。
为了满足高速率业务的需求,5G中支持载波聚合(Carrier Aggregation,CA)技术。CA是通过联合调度和使用多个成员载波(Component Carrier,CC)上的资源,使得5G系统可以支持更大的带宽,从而能够实现更高的系统峰值速率。根据所聚合的载波在频谱上的连续性可以分为如图1中101所示的非连续性载波聚合和图1中102所示的连续性载波聚合;根据聚合的载波所在的频带是否相同,分为Intra-band载波聚合和inter-band载波聚合。其中,在图1中的101中,对两个不连续的成员载波(成员载波A和成员载波B)进行聚合,一个成员载波的带宽为20MHz,载波聚合后的总带宽为40MHz;在图1中的102中,对五个连续的载波进行聚合,一个成员载波的带宽为20MHz,载波聚合后的总带宽为100MHz。
聚合的载波最多支持5个CC,即聚合后的最大带宽为100MHZ,并且聚合的载波属于同一个基站。所有聚合的载波使用相同的小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI),基站实现保证C-RNTI在每个载波所在的小区不发生冲突。
双连接的网络架构可如图2所示,包括:MCG和SCG。MCG包括一个PCell或额外包括一个或多个SCell,SCG包括一个PSCell或额外包括一个或多个SCell。MCG下的PCell和MCG下的SCell通过CA技术联合在一起。SCG下的PSCell和SCG下的SCell通过CA技术联合在一起。
PCell是终端设备如用户设备(User Equipment,UE)进行初始连接建立的小区,或进行无线资源控制(Radio Resource Control,RRC)连接重建的小区,或是在切换(handover)过程中指定的主小区。PCell负责与UE之间的RRC通信。PCell对应的成员载波称为主成员载波(Primary Component Carrier,PCC)。PCC有且只有一个,PCC提供RRC信令连接、非接入层(Non-Access Stratum,NAS)功能、安全等。物理上行控制信道(Physical Uplink Control Channel,PUCCH)在PCC上且只在PCC上存在。
SCell(Secondary Cell,辅小区)是在RRC重配置时添加的,用于提供额外的无线 资源。SCell对应的成员载波称为辅成员载波(Secondary Component Carrier,SCC)。
在NR早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的长期演进(Long Term Evolution,LTE)覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下,可用于NR的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资,提出了LTE和NR之间紧耦合(tight interworking)的工作模式。
在LTE和NR之间紧耦合(tight interworking)的工作模式下,可包括图3所示的几种架构:EN-DC、NE-DC、NGEN-DC和NR-DC构架。其中,E代表演进的通用移动通信系统(Universal Mobile Telecommunications System,UMTS)陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network,E-UTRAN),即4G无线接入网;N代表NR,即5G新无线;NG代表下一代核心网,即5G核心网。EN-DC为4G无线接入网与5G NR的双连接,EN-DC架构的网络部署如图3中的301:非独立组网(NSA)模式,连接4G核心网即演进型分组核心网(Evolved Packet Core network,EPC),LTE的演进型基站(Evolved Node B,eNB)为主站点,5G的基站(5G Node B,gNB)为辅站点。NE-DC为5G NR与4G无线接入网的双连接,NE-DC架构的网络部署如图3中的302:非独立组网(NSA)模式,连接增强的长期演进(Enhanced LTE,eLTE)的核心网即下一代核心网(NextGen Core),gNB为主站点,eNB为辅站点。NGEN-DC为5G核心网下的4G无线接入网与5G NR的双连接,NGEN-DC架构的网络部署如图3中的303:非独立组网(NSA)模式,连接下一代核心网,eNB为主站点,gNB为辅站点。NR-DC为5G NR与5G NR的双连接,NR-DC架构的网络部署如图3中的304:非独立组网(NSA)模式,连接下一代核心网,gNB为主站点,gNB为辅站点。
主站点负责主要的RRC控制功能以及通向CN的控制面,辅站点配置辅助的信令,例如SRB3,主要提供数据传输功能。
在一示例中,EN-DC的整体组网架构可如图4所示,接入网为E-UTRAN,其基站包括:接入4G核心网的5G基站en-gNB和4G基站eNB。核心网的网元包括:移动性管理实体(Mobility Management Entity,MME)/服务网关(Serving GateWay,S-GW)。其中,en-gNB和核心网之间的接口称为S1-U接口,eNB和核心网之间的接口称为S1接口,en-gNB和eNB之间的接口称为X2接口,en-gNB和en-gNB之间的接口称为X2-U接口。
Rel-15标准中对E-UTRAN和NR的双连接(MR-DC)场景,支持MN触发的PSCell添加过程,即SN添加过程;同时支持MN触发的和SN触发的两种PSCell变更过程,PScell的变更可以发生在同一个SN内部,也可以发生在不同的SN之间(即源SN和目标SN之间)。
条件切换
针对高速移动场景和高频部署场景存在频繁切换以及切换容易失败的问题,3GPP当前正在讨论为LTE和NR系统引入基于条件触发的切换过程即条件切换。条件切换的基本原理是终端设备根据网络侧配置的触发条件在评估与目标小区相关的触发条件被触发时,按照预先配置好的切换命令执行向该目标小区的切换(即触发随机接入过程和发送切换完成消息),避免由于高速移动进入覆盖差区域来不及或无法发送测量上报和接收到切换命令的问题。
条件切换的方法如图5所示,包括:
步骤501,源基站与UE之间进行测量控制信息和测量报告的交互。
源基站向UE配置测量控制信息,使UE测量源基站控制连接下的移动性功能。UE根据预定的规则发送测量报告(MEASUREMENT REPORT)。
步骤502,目标基站与源基站执行切换准备。
当源基站基于UE上报的测量结果确定UE存在切换的可能时,执行切换准备,向目标基站发送指示获取切换条件的请求消息。
步骤503,源基站向UE发送携带切换条件的切换命令。
在切换命令中携带目标基站发送的切换条件,这里,切换命令中可携带一个或多个目标基站的切换条件。
步骤504,当UE满足切换条件时,切换至目标基站。
Rel-16移动性增强课题引入了条件切换的概念,最初是针对PCell切换引入的,而后针对MR-DC场景决定引入基于条件触发的PSCell添加/变更(addition/change)。
引入基于条件触发的PSCell添加/变更后,PSCell的添加/变更不再完全受网络控制,即网络侧(即源MN和源SN)无法准确获知UE何时满足条件触发PScell添加/变更过程,这样,基于源主小区执行PCell切换或无线资源控制连接重建等RCC连接改变时,新的MN和PSCell添加/变更后新的PSCell所在的SN之间由于之前没有协调(例如没有X2/Xn接口),而无法通过DC模式为UE服务,造成系统出错。
基于上述问题,本发明实施例提供一种接入控制方法,本发明实施例的接入控制方法可以应用于各种通信系统,例如:LTE系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)通信系统、5G系统或未来的通信系统等。

可选地,以终端设备开始执行从所述源主小区向所述目标主小区的切换的时机可在终端设备满足第一触发条件之后为例。在一示例中,在满足第一触发条件的情况下,终端设备执行的向目标主辅小区的接入,在执行的向目标主辅小区的接入的过程中,满足无线资源控制连接转移的条件,则终止或中止正在执行的向目标主辅小区的接入,执行从所述源主小区向所述目标主小区的切换。在又一示例中,终端设备满足第一触发条件且满足无线资源控制连接转移的条件,则开始执行从所述源主小区向所述目标主小区的切换,且不执行待执行的向目标主辅小区的接入。
本发明实施例中,终端设备存在RRC连接失败、需进行主小区切换等无线资源控制连接发生改变导致终端设备可能与新的主小区建立无线连接的情况下,终端设备忽略基于第一触发条件触发的PSCell的添加/变更,避免覆盖新的PCell的MN与覆盖新的PSCell的SN之间不存在接口的情况的发生,从而保证终端设备的双连接功能的正常。
可选地,终端设备在满足第一触发条件之后,执行向目标主辅小区的接入,在执行向目标主辅小区的接入的过程中,检测到RRC连接失败、接收到切换命令或满足 第二触发条件,则终止正在执行的向目标主辅小区的接入,删除目标PSCell相关配置和第一触发条件配置,并发起RRC连接重建过程或执行向目标主小区的切换。
可选地,终端设备检测到RRC连接失败、接收到切换命令或满足第二触发条件,在向目标主小区的切换过程中或发起RRC连接重建过程中,终端设备满足触发向目标主辅小区接入的第一触发条件,则删除目标PSCell相关配置和第一触发条件配置。

需要说明的是,以上4种场景为应用场景地示例性描述,本发明实施例提供的接入控制方法还可包括其他应用场景,这里不再赘述。

下面,以通信系统为NR/5G系统为例,通过不同的实例对本发明实施例提供的接入控制方法进行举例说明。
实例一
在实例一中,基于PCell切换命令的接收终止正在进行的基于条件触发的PSCell addition/change过程,如图10所示,包括:
步骤S1001,源MN为连接态UE配置第一触发条件。
第一触发条件为PSCell addition/change的触发条件。
这里,在步骤S1001中,源基站还为连接态UE配置PSCell相关配置。
a.当UE工作在非DC模式(即只有MN)下,源MN通过RRC重配置消息配置给UE用于PSCell addition的触发条件和目标PSCell的相关配置,触发条件可以包括A3/A5/A4/B1等无线资源管理(Radio Resource Management,RRM)测量事件;
b.当UE工作在DC模式(即MN和SN)下,PSCell change的触发条件和目标PSCell相关配置可以由源MN在SRB1上通过RRC重配置消息配置给UE,或者源SN在SRB3上通过RRC重配置消息配置给UE。
步骤S1002,当第一触发条件满足时,UE发起向目标SN的覆盖范围内的目标PSCell的接入。
步骤S1003-步骤S1004,UE在向目标PSCell接入时继续接收源MN发送的RRC消息,如果目标PSCell接入尚未成功(例如随机接入尚未成功)时UE收到源MN发送的PCell切换命令,则UE终止正在进行的目标PSCell接入,恢复源PSCell配置。
步骤S1005,UE向目标MN覆盖范围下的目标PCell切换。
UE终止正在进行的目标PSCell接入,恢复源PSCell配置后,立即执行PCell切换过程,以从源PCell切换至目标PCell。
在实施例一中,当PCell切换命令中如果未涉及PSCell配置,则UE在切换后继续使用源PSCell的配置;若PCell切换命令中指示了新的PSCell(例如更换了新的PSCell)配置,则UE在切换后应用新的PSCell配置。
在实例一中,基于条件触发的PSCell addition/change是UE侧根据条件评估自动触发,网络侧没有绝对控制。用PCell切换终止正在进行的基于条件触发的PSCell addition/change过程能够保证连接态的移动性完全受网络侧控制,避免同时执行PCell切换和PSCell addition/change后新的目标PSCell小区和切换后的目标MN之间由于之前没有协调(例如没有X2/Xn接口)而无法通过DC模式为UE服务,造成系统出错。
实例二
在实例二中,基于PCell条件切换过程终止正在进行的基于条件触发的PSCell addition/change过程,如图11所示,
步骤S1101,源MN为连接态UE配置第一触发条件和第二触发条件。
第一触发条件为PSCell addition/change的触发条件,第二触发条件为PCell切换的触发条件。
这里,在步骤S1101中,源基站还为连接态UE配置PCell的相关配置和PSCell的相关配置。
a.源MN通过RRC重配置消息配置给UE用于PCell切换的触发条件和目标PSCell的相关配置,触发条件可以包括:A3/A5等RRM测量事件;
b.当UE工作在非DC模式(即只有MN)下,源MN通过RRC重配置消息配置给UE用于PSCell addition的触发条件和目标PSCell的相关配置,触发条件可以包括:A3/A5/A4/B1等RRM测量事件;
c.当UE工作在DC模式(即MN和SN)下,PSCell change的触发条件和目标PSCell相关配置可以由源MN在SRB1上通过RRC重配置消息配置给UE,或者源SN在SRB3上通过RRC重配置消息配置给UE;
步骤S1102,当第一触发条件满足时,UE发起向目标SN的覆盖范围内的目标PSCell的接入。
步骤S1103-步骤S1104,UE在向目标PSCell接入时继续接收源MN发送的RRC消息,如果目标PSCell接入尚未成功(例如随机接入尚未成功)时UEUE侧评估满足第二触发条件,则UE终止正在进行的目标PSCell接入,恢复源PSCell配置。
步骤S1105,UE向目标MN覆盖范围下的目标PCell切换。
UE终止正在进行的目标PSCell接入,恢复源PSCell配置后,立即执行PCell切换过程,以从源PCell切换至目标PCell。
在实例二中,基于条件触发的PCell切换和基于条件触发的PSCell addition/change是两个独立的过程,两者之间存在冲突。例如,基于条件触发的PCell切换的目标PCell所在的目标MN可能与基于条件触发的PSCell addition/update的目标PSCell所在的目标SN之间没有X2/Xn接口。基于PCell切换终止正在进行的基于条件触发的PSCell addition/change过程能够避免同时执行PCell切换和PSCell addition/change后新的目标PSCell小区和切换后的目标MN之间由于之前没有协调而无法通过DC模式为UE服务,造成系统出错。
实例三
在实例三中,PCell切换的触发条件和PSCell addition/change的触发条件同时满足时执行PCell切换过程。如图12所示,包括:
步骤S1201,源MN为连接态UE配置第一触发条件和第二触发条件。
第一触发条件为PSCell addition/change的触发条件,第二触发条件为PCell切换的触发条件。
这里,在步骤S1201中,源基站还为连接态UE配置PCell的相关配置和PSCell的相关配置。
步骤S1202,当第一触发条件和第二触发条件同时满足时,执行PCell切换过程,向目标MN覆盖范围下的目标PCell切换。
这里,当PSCell addition/change的触发条件和PCell切换的触发条件同时满足时,UE并不同时发起向目标PCell和目标PSCell的接入,UE忽略PSCell addition/change触发条件已满足的事实,依据PCell切换触发条件满足,使用PCell条件切换相关的配置向目标PCell发起接入。
步骤S1203,UE将目标PSCell满足PSCell addition/change条件的指示信息在PCell切换完成后上报给目标PCell/MN。
a.该指示信息可以包含目标PSCell的频点和PCI信息;
b.该指示信息可以在切换完成消息中(例如RRCReconfigurationComplete消息)携带;
c.该指示信息可以在RRCReconfigurationComplete消息之后的RRC消息中(例如ULInformationTransfer消息)携带;
步骤S1204,目标MN可以利用该指示信息立即向目标SN发起向该目标PSCell的添加/变更请求,用于UE添加或更换PScell。
在实例三中,不同时执行PCell切换和PScell addition/change能够避免系统出错的同时,在PCell切换完成后,立即上报可用的目标PSCell能够辅助新的MN立即发起新的PScell添加或更换,避免了由于需要网络重新配置测量和接收测量报告而引入的额外时延,能够快速进入DC配置,提高用户体验。
实例四
在实例四中,PCell切换/条件切换正在执行时PSCell addition/change条件满足,则执行PCell切换过程。如图13所示,包括:
步骤S1301,源MN为连接态UE配置第一触发条件和第二触发条件。
步骤S1302,当PCell切换触发条件满足时或者UE收到PCell切换命令时,UE发起向目标MN覆盖范围内的目标PCell的接入。
步骤S1303,在目标PCell的接入的过程中,UE不执行向目标SN向的目标PSCell的接入。
针对UE发起向目标PCell接入时PSCell addition/change的处理,,UE不执行向目标SN向的目标PSCell的接入,包括以下几种处理方式:
a.UE停止评估PSCell addition/change触发条件,和/或UE删除目标PSCell相关配置;
b.UE继续评估触发条件,当满足触发条件时并不执行PSCell addition/change过程。
其中,如果UE继续评估触发条件,UE可以将目标PSCell满足PSCell addition/change条件的指示信息在PCell切换完成后上报给目标PCell/MN;
a.该指示信息可以在切换完成消息中(例如RRCReconfigurationComplete消息)携带;
b.该指示信息可以在RRCReconfigurationComplete消息之后的RRC消息中(例如ULInformationTransfer消息)携带。
步骤1304,目标PCell/MN可以利用该上报信息向目标SN立即发起向目标PSCell/SN的addition/update请求,用于UE添加或更换PScell。
在实例四中,不同时执行PCell切换和PScell addition/change能够避免系统出错的同时,切换完成后立即上报可用的目标PSCell能够辅助新的MN立即发起新的PScell添加或更换,避免了由于需要网络重新配置测量和接收测量报告而引入的额外时延,能够快速进入DC配置,提高用户体验。
实例五
在实例五中,PCell无线链路失败终止正在进行的PSCell addition/change过程,触发RRC连接重建。如图14所示,包括:
步骤S1401,源MN为连接态UE配置第一触发条件。
步骤S1402,当第一触发条件满足时,UE发起向目标SN覆盖范围下的目标PSCell的接入。
步骤S1403-步骤S1404,在PSCell addition/change执行过程中,UE继续对PCell进行无线链路监测(RLM:radio link monitoring),若PCell发生无线链路失败(RLF),则UE停止正在进行的PSCell addition/change过程。
步骤S1405,UE发起RRC连接重建过程。
在步骤S1405之前,UE可删除目标PSCell相关配置,
在实例五中,PCell无线链路失败时停止正在进行的PSCell addition/change过程可以避免UE重建到新的MN/PCell下,由于新的MN/PCell和目标PSCell之间没有X2/Xn接口/协调而导致DC无法在新的MN下工作。
为实现上述接入控制方法,本发明实施例提供一种终端设备1500,如图15,包括:
忽略模块1501,配置为在终端设备满足无线资源控制连接重建或转移的条件时或在终端设备正在进行无线资源控制连接重建或转移的过程中:
