为便于理解本申请实施例的技术方案,以下对本申请实施例相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此第三代合作伙伴计划(3 rd Generation Partnership Project,3GPP)国际标准组织开始研发5G。5G的主要应用场景为: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 Communications,mMTC)。
一方面,eMBB仍然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,例如室内,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。
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5G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。

RRC状态
5G为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC激活(RRC_ACTIVE)状态。其中,
1)RRC_IDLE状态(简称为空闲(idle)态):移动性为基于UE的小区选择重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。基站侧不存在UE上下文,不存在RRC连接。
2)RRC_CONNECTED状态(简称为连接(connected)态):存在RRC连接,基站侧和UE侧存在UE上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
3)RRC_INACTIVE状态(简称为非激活(inactive)态):移动性为基于UE的小区选择重选,存在CN-NR之间的连接,UE上下文存在某个基站上,寻呼由RAN触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。

MBMS
MBMS是一种通过共享网络资源从一个数据源向多个终端设备传送数据的技术,该技术在提供多媒体业务的同时能有效地利用网络资源,实现较高速率(如256kbps)的多媒体业务的广播和组播。
由于MBMS频谱效率较低,不足以有效地承载和支撑手机电视类型业务的运营。因此在LTE中,3GPP明确提出增强对下行高速MBMS业务的支持能力,并确定了对物理层和空中接口的设计要求。
3GPP R9将演进的MBMS(evolved MBMS,eMBMS)引入到LTE中。eMBMS提出了单频率网络(Single Frequency Network,SFN)的概念,即多媒体广播多播服务单频率网络(Multimedia Broadcast multicast service Single Frequency Network,MBSFN),MBSFN采用统一频率在所有小区同时发送业务数据,但是要保证小区间的同步。这种方式可以极大的提高小区整体信噪比分布,频谱效率也会相应的大幅提高。eMBMS基于IP多播协议实现业务的广播和多播。
在LTE或增强的LTE(LTE-Advanced,LTE-A)中,MBMS只有广播承载模式,没有多播承载模式。此外,MBMS业务的接收适用于空闲态或者连接态的终端设备。
3GPP R13中引入了单小区点对多点(Single Cell Point To Multiploint,SC-PTM)概念,SC-PTM基于MBMS网络架构。
MBMS引入了新的逻辑信道,包括单小区多播控制信道(Single Cell-Multicast Control Channel,SC-MCCH)和单小区多播传输信道(Single Cell-Multicast Transport Channel,SC-MTCH)。SC-MCCH和SC-MTCH被映射到下行共享信道(Downlink-Shared Channel,DL-SCH)上,进一步,DL-SCH被映射到物理下行共享信道(Physical Downlink Shared Channel,PDSCH)上,其中,SC-MCCH和SC-MTCH属于逻辑信道,DL-SCH 属于传输信道,PDSCH属于物理信道。SC-MCCH和SC-MTCH不支持混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)操作。
MBMS引入了新的系统信息块(System Information Block,SIB)类型,即SIB20。具体地,通过SIB20来传输SC-MCCH的配置信息,一个小区只有一个SC-MCCH。SC-MCCH的配置信息包括:SC-MCCH的修改周期、SC-MCCH的重复周期、以及调度SC-MCCH的无线帧和子帧等信息。进一步,1)SC-MCCH的修改周期的边界满足SFN mod m=0,其中,SFN代表边界的系统帧号,m是SIB20中配置的SC-MCCH的修改周期(即sc-mcch-ModificationPeriod)。2)调度SC-MCCH的无线帧满足:SFN mod mcch-RepetitionPeriod=mcch-Offset,其中,SFN代表无线帧的系统帧号,mcch-RepetitionPeriod代表SC-MCCH的重复周期,mcch-Offset代表SC-MCCH的偏移量。3)调度SC-MCCH的子帧通过sc-mcch-Subframe指示。
SC-MCCH通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度。一方面,引入新的无线网络临时标识(Radio Network Tempory Identity,RNTI),即单小区RNTI(Single Cell RNTI,SC-RNTI)来识别用于调度SC-MCCH的PDCCH(如SC-MCCH PDCCH),可选地,SC-RNTI固定取值为FFFC。另一方面,引入新的RNTI,即单小区通知RNTI(Single Cell Notification RNTI,SC-N-RNTI)来识别用于指示SC-MCCH的变更通知的PDCCH(如通知PDCCH),可选地,SC-N-RNTI固定取值为FFFB;进一步,可以用DCI 1C的8个比特(bit)中的一个bit来指示变更通知。在LTE中,SC-PTM的配置信息基于SIB20配置的SC-MCCH,然后SC-MCCH配置SC-MTCH,SC-MTCH用于传输业务数据。
具体地,SC-MCCH只传输一个消息(即SCPTMConfiguration),该消息用于配置SC-PTM的配置信息。SC-PTM的配置信息包括:临时移动组标识(Temporary Mobile Group Identity,TMGI)、会话标识(seession id)、组RNTI(Group RNTI,G-RNTI)、非连续接收(Discontinuous Reception,DRX)配置信息以及邻区的SC-PTM业务信息等。需要说明的是,R13中的SC-PTM不支持健壮性包头压缩(Robust Header Compression,ROHC)功能。
SC-PTM的下行非连续的接收是通过以下参数控制的:onDurationTimerSCPTM、drx-InactivityTimerSCPTM、SC-MTCH-SchedulingCycle、以及SC-MTCH-SchedulingOffset。
当满足[(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset时,启动定时器onDurationTimerSCPTM;
当接收到下行PDCCH调度时,启动定时器drx-InactivityTimerSCPTM;
只有当定时器onDurationTimerSCPTM或drx-InactivityTimerSCPTM运行时才接收下行SC-PTM业务。
SC-PTM业务连续性采用基于SIB15的MBMS业务连续性概念,即“SIB15+MBMSInterestIndication”方式。空闲态的终端设备的业务连续性基于频率优先级的概念。
本申请实施例的技术方案中,定义一个新的SIB(称为第一SIB),第一SIB包括第一MCCH的配置信息,这里,第一MCCH为MBMS业务的控制信道,换句话说,第一SIB用于配置NR MBMS的控制信道的配置信息,可选地,NR MBMS的控制信道也可以叫做NR MCCH(即所述第一MCCH)。
进一步,第一MCCH用于承载第一信令,本申请实施例对第一信令的名称不做限定,如第一信令为信令A,所述第一信令包括至少一个第一MTCH的配置信息,这里,第一MTCH为MBMS业务的业务信道(也称为数据信道或传输信道),第一MTCH用 于传输MBMS业务数据(如NR MBMS的业务数据)。换句话说,第一MCCH用于配置NR MBMS的业务信道的配置信息,可选地,NR MBMS的业务信道也可以叫做NR MTCH(即所述第一MTCH)。
具体地,所述第一信令用于配置NR MBMS的业务信道、该业务信道对应的业务信息以及该业务信道对应的调度信息。进一步,可选地,所述业务信道对应的业务信息,例如TMGI、session id等标识业务的标识信息。所述业务信道对应的调度信息,例如业务信道对应的MBMS业务数据被调度时使用的RNTI,例如G-RNTI、DRX配置信息等。
需要说明的是,第一MCCH和第一MTCH的传输都是基于PDCCH调度的。其中,用于调度第一MCCH的PDCCH使用的RNTI使用全网唯一标识,即是一个固定值。用于调度第一MTCH的PDCCH使用的RNTI通过第一MCCH进行配置。
需要说明的是,本申请实施例对所述第一SIB、所述第一MCCH和所述第一MTCH的命名不做限制。为便于描述,所述第一SIB也可以简称为SIB,所述第一MCCH也可以简称为MCCH,所述第一MTCH也可以简称为MTCH,通过SIB配置用于调度MCCH的PDCCH(即MCCH PDCCH)以及通知PDCCH,其中,通过MCCH PDCCH携带的DCI调度用于传输MCCH的PDSCH(即MCCH PDSCH)。进一步,通过MCCH配置M个用于调度MTCH的PDCCH(即MTCH 1 PDCCH、MTCH 2 PDCCH、…、MTCH M PDCCH),其中,MTCH n PDCCH携带的DCI调度用于传输MTCH n的PDSCH(即MTCH n PDSCH),n为大于等于1且小于等于M的整数。MCCH和MTCH被映射到DL-SCH上,进一步,DL-SCH被映射到PDSCH上,其中,MCCH和MTCH属于逻辑信道,DL-SCH属于传输信道,PDSCH属于物理信道。
需要说明的是,上述方案中的MBMS业务包括但不局限于多播业务、组播业务。本申请实施例以MBS业务为例进行说明,“MBS业务”的描述也可以被替换为“多播业务”或者“组播业务”或者“MBMS业务”。
在NR MBS中,MBS业务的传输网络架构如图2所示,5G核心网通过共享GTP隧道传递MBS业务流到5G接入网(如gNB),5G接入网可以判断通过点对点(Point To Point,PTP)方式或者点对多点(Point To Multipoint,PTM)方式传递MBS业务流给终端设备。
对于接收MBS业务的终端设备来说,同时还会接收其他非MBS业务,例如eMBB业务。所以当没有MBS业务传输的时候,终端设备可以被网络侧释放到空闲态或者非激活态或者保持在连接态。在终端设备处于空闲态或者非激活态的情况下,当MBS业务的数据到达时,网络侧可以通过寻呼来唤醒终端设备来接收MBS业务。
在NR中,对应同一寻呼时机(Paging Occasion,PO)的多个用户的寻呼可以复用在一个寻呼消息中,所以一个PO对应的多个用户都会监听MBS业务的寻呼消息,即使某些用户没有参与该MBS业务,MBS业务的寻呼消息也会务唤醒这些用户,对这些用户造成影响,例如造成这些用户费电。此外,NR支持波束扫描(beam sweeping)传输,所以一个寻呼消息在一个小区中会传输多份,具体份数取决于该小区实际传输的同步信号块(Synchronization Signal Block,SSB)个数,这样,MBS业务的寻呼消息会有很高的负荷,浪费了无线资源。基于此,本申请实施例考虑缩小MBS业务的寻呼区域,这无论对于网络无线资源的节省还是其他没有参与MBS业务的用户的电力节省都是有益的。
图3是本申请实施例提供的MBS业务的管理方法的流程示意图,如图3所示,所述MBS业务的管理方法包括以下步骤:
步骤301:网络设备向终端设备发送RRC释放消息,终端设备接收网络设备发送的RRC释放消息,所述RRC释放消息用于触发所述终端设备进入空闲态或者非激活态, 其中,所述RRC释放消息携带第一指示信息,所述第一指示信息用于指示MBS业务处于悬挂状态还是释放状态。
本申请实施例中,网络设备可以是基站,如gNB。对于配置了某个MBS业务的终端设备,如果该MBS业务没有数据传输,但是该MBS业务没有被释放,则网络设备可以释放终端设备进入空闲态或者非激活态或者维持在连接态。终端设备进入空闲态或者非激活态的情况下,当MBS业务的数据达到时,网络侧会在特定的寻呼区域内寻呼该终端设备,从而唤醒该终端设备进行MBS业务的接收。终端设备进入连接态的情况下,当MBS业务的数据达到时,网络侧会将MBS业务数据下发给终端设备。
需要说明的是,MBS业务没有被释放表现在该MBS业务对应的从核心网到接入网的GTP隧道没有被释放。
本申请实施例中,网络侧会在特定的寻呼区域内寻呼该终端设备,为了避免寻呼对非MBS业务的终端设备(即不参与该MBS业务的终端设备)的影响,可以通过以下方案来实现。
方案一:限制MBS业务去激活后的RRC状态
具体地,对于配置了MBS业务的终端设备,且该MBS业务没有被释放,只是暂时没有MBS业务的数据传输,则限制终端设备不能进入空闲态。
这里,终端设备在空闲态下,寻呼由核心网触发,且寻呼区域为核心网管理的TA列表(TA list)。而非激活态下,寻呼由接入网触发,且寻呼区域为核心网管理的无线接入网管理区域(RAN Notification Area,RNA)。由于TA列表的范围过大,在该寻呼区域内下发寻呼消息会影响较多数目的终端设备,因而限制终端设备不能进入空闲态。
本申请实施例中,限制终端设备不能进入空闲态,包括:网络侧通过RRC释放消息触发终端设备进入非激活态或者维持终端设备在连接态。
本申请实施例中,所述RRC释放消息携带第一指示信息,所述第一指示信息用于指示指定的MBS业务处于悬挂状态还是释放状态。例如:所述第一指示信息为1比特指示信息,1比特指示信息的取值为1表示MBS业务处于悬挂状态,1比特指示信息的取值为0表示MBS业务处于释放状态;或者,1比特指示信息的取值为0表示MBS业务处于悬挂状态,1比特指示信息的取值为1表示MBS业务处于释放状态。
在一可选方式中,所述RRC释放消息还携带所述MBS业务的业务标识。进一步,所述业务标识包括以下至少之一:G-RNTI、TMGI、MBS会话标识。
在一可选方式中,所述第一指示信息指示MBS业务处于悬挂状态的情况下,网络侧可以指示终端设备保存所述MBS业务的业务标识,从而可以为后续监听该MBS业务的MBS信令提供依据。具体地,1)所述RRC释放消息还携带第二指示信息,所述第二指示信息用于指示所述终端设备保存所述MBS业务的业务标识;或者,2)所述第一指示信息还用于指示所述终端设备保存所述MBS业务的业务标识。
方案二:限制寻呼区域的范围为MBS寻呼区域
具体地,对于配置了MBS业务的终端设备,且该MBS业务没有被释放,只是暂时没有MBS业务的数据传输,则网络侧可以通过RRC释放消息触发终端设备进入空闲态或者非激活态或者维持在连接态。
本申请实施例中,所述RRC释放消息还携带第三指示信息,所述第三指示信息用于指示MBS寻呼区域,所述MBS寻呼区域用于确定所述终端设备的寻呼范围。这里,对于空闲态来说,MBS寻呼区域小于TA列表,从而可以避免寻呼对非MBS业务的终端设备(即不参与该MBS业务的终端设备)的影响。对于非激活态来说,MBS寻呼区域可以与RNA相同或者不同,进一步,可选地,MBS寻呼区域小于RNA。以下结合不同的RRC状态,对MBS寻呼区域的实现进行说明。
A)所述RRC释放消息用于触发所述终端设备进入空闲态,所述RRC释放消息中携带的所述第一指示信息用于指示第一MBS寻呼区域。
这里,对于空闲态的终端设备来说,所述终端设备在所述第一MBS寻呼区域内执行小区重选行为;所述终端设备移出所述第一MBS寻呼区域的情况下,向所述网络设备上报位置更新请求消息,接收所述网络设备发送的位置更新响应消息,所述位置更新响应消息用于确定更新的MBS寻呼区域。
在一可选方式中,所述终端设备向所述网络设备发送第一配置信息,所述网络设备接收所述终端设备发送的第一配置信息,所述第一配置信息用于确定所述终端设备建议的MBS寻呼区域,所述终端设备建议的MBS寻呼区域用于所述网络设备确定所述第一MBS寻呼区域,其中,所述第一MBS寻呼区域与所述终端设备建议的MBS寻呼区域相同或者不同。
在一可选方式中,所述第一MBS寻呼区域由核心网网元管理。这里,核心网网元例如是AMF。
本申请实施例中,所述第一MBS寻呼区域的配置粒度可以是per UE的,即所述第一MBS寻呼区域为针对所述终端设备的MBS寻呼区域。或者,所述第一MBS寻呼区域的配置粒度可以是per MBS业务(或者说per MBS session)的,即所述第一MBS寻呼区域为针对所述MBS业务的MBS寻呼区域。
在一个示例中,第一MBS寻呼区域是per UE的,对于释放到空闲态的终端设备来说,RRC释放消息中携带第三指示信息用于指示第一MBS寻呼区域,终端设备在第一MBS寻呼区域内执行小区重选不需要上报网络侧,但是当终端设备移出该第一MBS寻呼区域时需要向网络侧上报位置更新请求消息,从而实现位置更新。可选地,终端设备可以向网络侧发送自己建议的寻呼区域的配置信息,网络侧据此判决第一MBS寻呼区域并配置给终端设备。第一MBS寻呼区域可以在AMF处维护(即管理),或者在基站处维护。
在一个示例中,第一MBS寻呼区域是per MBS session的,对于释放到空闲态的终端设备来说,RRC释放消息中携带第三指示信息用于指示第一MBS寻呼区域,终端设备在第一MBS寻呼区域内执行小区重选不需要上报网络侧,但是当终端设备移出该第一MBS寻呼区域时需要向网络侧上报位置更新请求消息,从而实现位置更新。可选地,终端设备可以向网络侧发送自己建议的寻呼区域的配置信息,网络侧据此判决第一MBS寻呼区域并配置给终端设备。第一MBS寻呼区域可以在AMF处维护(即管理)。
上述方案中,对于第一MBS寻呼区域是per UE的情况来说,不同的终端设备各自被配置有独立的第一MBS寻呼区域,例如:UE1被配置MBS寻呼区域1,UE2被配置MBS寻呼区域2。终端设备移出第一MBS寻呼区域后,对自己的MBS寻呼区域进行更新即可。
上述方案中,对于第一MBS寻呼区域是per MBS session的情况来说,不同的MBS业务(即MBS会话)被配置有独立的第一MBS寻呼区域,例如:MBS业务1被配置MBS寻呼区域1,MBS业务2被配置MBS寻呼区域2。终端设备移出第一MBS寻呼区域后,对自己的MBS寻呼区域进行更新,由于更新后的MBS寻呼区域同样适用于该MBS业务的其他终端设备,因而所述MBS业务对应的多播组中的除所述终端设备以外的其他终端设备的更新的MBS寻呼区域基于第一MBS信令确定,所述第一MBS信令的调度信息通过所述MBS业务对应的G-RNTI加扰。
具体地,对于MBS业务的多播组中的其他终端设备的第一MBS寻呼区域的更新,网络侧通过该MBS业务对应的G-RNTI调度的MBS信令来更新第一MBS寻呼 区域。当终端设备进入空闲态后至少保存MBS业务的业务标识(如G-RNTI,TMGI),从而可以利用MBS业务的业务标识接收MBS信令,进而更新第一MBS寻呼区域。
B)所述RRC释放消息用于触发所述终端设备进入非激活态,所述RRC释放消息中携带的所述第一指示信息用于指示第二MBS寻呼区域。
这里,对于非激活态的终端设备来说,所述终端设备在所述第二MBS寻呼区域内执行小区重选行为;所述终端设备移出所述第二MBS寻呼区域的情况下,向所述网络设备上报位置更新请求消息,接收所述网络设备发送的位置更新响应消息,所述位置更新响应消息用于确定更新的MBS寻呼区域。
在一可选方式中,所述第二MBS寻呼区域由接入网网元管理。这里,所述接入网网元例如是gNB。
本申请实施例中,所述第二MBS寻呼区域与RNA相同;或者,所述第二MBS寻呼区域与RNA不同。
本申请实施例中,当MBS业务的数据达到时,网络侧发送在MBS寻呼区域内下发寻呼消息。可选地,AMF也会将MBS业务的多播组的MBS寻呼区域发送给基站。
方案三:为MBS寻呼定义独立的MBS P-RNTI、搜空空间和寻呼时机中的至少之一。
本申请实施例中,所述终端设备基于MBS P-RNTI在MBS寻呼搜索空间和/或MBS寻呼时机上,监听MBS寻呼消息的调度信息,所述调度信息承载在MBS唤醒PDCCH中。
A)这里,MBS P-RNTI为MBS业务专用的P-RNTI,用于寻呼支持MBS业务的终端设备。本申请实施例定义一个MBS P-RNTI专门用于监听MBS业务的寻呼消息的调度信息或者MBS唤醒PDCCH。

上述方案中,所述MBS寻呼消息或者所述MBS唤醒PDCCH携带MBS唤醒指示信息,所述MBS唤醒指示信息用于指示唤醒MBS业务。例如:所述MBS唤醒指示信息携带某个MBS业务的业务标识(如TMGI),从而指示唤醒该业务标识对应的MBS业务。
B)这里,MBS寻呼搜索空间(MBS paging search space)为MBS业务专用的寻呼搜索空间。本申请实施例定义一个MBS寻呼搜索空间专门用于接收MBS寻呼消息的调度信息(也即MSB寻呼DCI,MSB寻呼DCI用于承载MBS寻呼消息的调度信息,MSB寻呼DCI承载在MBS唤醒PDCCH中)。
在一可选方式中,所述MBS寻呼搜索空间为针对小区(即per cell)的寻呼搜索空间,所述MBS寻呼搜索空间通过系统广播信息配置。

这种情况,不同MBS业务和/或不同终端设备使用的MBS寻呼搜索空间不同。例如:同一终端设备针对不同MBS业务使用的MBS寻呼搜索空间不同。例如:不同终端设备针对同一MBS业务使用的MBS寻呼搜索空间不同。
