具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例提供的小区接入方法进行详细说明之前,先对相关技术进行简要说明。
当前,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和复杂性,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(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications,URLLC)、和大规模机器类通信(Massive Machine Type Communication,mMTC)。
新无线(New Radio,NR)系统也可以独立部署,为了降低空口信令、快速恢复无线连接和快速恢复数据业务,定义了新的无线资源控制(Radio Resource Control,RRC)状态,即去激活(RRC-Inactive)状态。其中,空闲(RRC-Idle)状态下,移动性为基于终端设备的小区重选,寻呼过程由核心网(Core Network,CN)发起,寻呼区域由CN配置。网络设备侧不存在终端设备上下文,也不存在RRC连接。RRC-Inactive状态下,移动性为基于终端设备的小区重选,存在CN-NR之间的连接,终端设备上下文存在于某个网络设备上,寻呼过程由RAN触发,基于RAN的寻呼区域由RAN管理,网络设备能够知道终端设备的位置是基于RAN的寻呼区域级别的。连接(RRC-Connected)状态下,存在RRC连接,网络设备和终端设备之间存在终端设备上下文,网络设备知道终端设备的位置是具体小区级别的;移动性是网络设备控制的移动性,网络设备与终端设备之间可以传输单播数据。
下面再对小区重选(cell reselection)进行简要介绍。
小区重选指终端设备在空闲模式下通过监测邻区的信号质量和当前小区的信号质量以选择一个最好的小区提供服务信号的过程。当邻区的信号质量及电平满足S准则且满足一定重选判决准则时,终端设备将接入该小区驻留。
终端设备成功驻留小区后,终端设备将持续进行本小区测量。无线资源控制(Radio Resource Control,RRC)层根据参考信号接收功率(Reference Signal Receiving Power,RSRP)测量结果计算Srxlev(即S准则),并将计算得到的Srxlev与同频测量启动门限(Sintrasearch)和异频/异系统测量启动门限(Snonintrasearch)比较,作为是否启动邻区测量的判决条件。
下面介绍针对RRC-idle状态和RRC-inactive状态的小区重选R准则以及候选小区选择:
同频小区和同优先级异频小区重选时遵循以下准则:
Rs=Qmeas,s+Q hyst-Q offsettemp
Rn=Qmeas,n-Q offset-Q offsettemp
其中,Qmeas,s是服务小区的RSRP测量值,Qmeas,n是邻小区的RSRP测量,Q offset是偏移值,Q offsettemp是临时偏移值,Q hyst是迟滞值。
如果网络设备没配置rangeToBestCell参数,则终端设备针对服务小区和邻小区的Rs和Rn值进行排序,在服务小区和众多的邻小区中选择Rs/Rn排序最高的小区进行小区重选。
如果网络设备配置了rangeToBestCell参数,则终端设备在由参数rangeToBestCell定义的最高 排序的多个小区中选择最优波束(beam)数最多的小区进行重选;其中最优beam由absThresh SS-BlocksConsolidation门限值来定义。如果最优beam数最多的小区有很多,则终端设备重选到排序最高的那个小区。
下面介绍高优先级异频小区重选时遵循的准则:
如果系统消息广播了Thresh ServingLowQ,当高优先级频点上的一个邻小区的参考信号接收质量(Reference Signal Receiving Quality,RSRQ)测量值大于Thresh X,HighQ门限值时,终端设备触发向该小区的重选过程;否则,高优先级频点上的一个邻小区的RSRP测量值满足大于Thresh X,HighP门限值时,终端设备触发向该小区的重选过程。
下面介绍低优先级异频小区重选时遵循的准则:
如果系统消息广播了thresh ServingLowQ,当服务小区的RSRQ测量值小于Thresh Serving,LowQ,且低优先级频点上的一个邻小区的RSRQ测量值大于Thresh X,HighQ门限值时,终端设备触发向该小区的重选过程;否则,当服务小区的RSRP测量值小于Thresh Serving,LowP,且低优先级频点上的一个邻小区的RSRP测量值大于Thresh X,HighP门限值时,终端设备触发向该小区的重选过程。
垂直行业对无线通信的强劲需求是有目共睹的,为了满足垂直行业对延迟、移动性、可靠性和位置精度等方面的需求,无线接入网(Radio Access Network,RAN)需要对如何在接入网支持垂直业务进行增强。其中,对接入网支持垂直业务进行增强的一种方式为,基于网络切片对不同需求的多个业务提供更低时延、更有目标性、更大的灵活性和更高的可扩展性服务。更具体地说,RAN slicing可以让应用程序提供商参与定制RAN的设计、部署和操作,以更好地支持应用程序提供商的业务。因此,Release 17(Rel-17)引入接入网对slicing的增强,具体涉及以下方面:
The study item aims to investigate enhancement on RAN support of network slicing.Detailed objectives of the study item are:
1.Study mechanisms to enable UE fast access to the cell supporting the intended slice,including
[RAN2]
a.Slice based cell reselection under network control
b.Slice based RACH configuration or access barring
Note:whether the existing mechanism can meet this scenario or requirement can be studied.
Release 15(Rel-15)中的网络切片仅涉及核心网侧。具体的,终端设备向往老设备上报自身的网络切片需求,网络设备根据终端设备上报的网络切片需求,选择合适的接入和移动性管理功能(Access and Mobility Management Function,AMF)实体,以建立终端设备和网络设备之间的业务会话。
目前RAN侧针对每一个网络切片定义了S-NSSAI,终端设备维护一个NSSAI,NSSAI是一个S-NSSAI列表,S-NSSAI列表最多包括8个S-NSSAI。
在RAN侧引入网络切片之后,不同小区支持的网络切片可能会不同,不同的网络切片对应的AMF实体也可以不相同;因此,需要辅助网络设备有效的选择一个合适的AMF实体,以便网络设备为终端设备配置终端设备所需的网络切片。
本申请人在实施小区重选的过程中,发现终端设备进行小区重选后,与网络切片相关的业务的传输性能会降低,是由于终端设备按照相关技术中根据参考信号质量和beam进行小区重选时可能会重选到非终端设备支持的最优的网络切片的小区;基于此本申请实施例提供一种基于网络切片信息进行小区重选的小区重选方法。
本申请实施例的提供的小区重选方法可以应用于各种通信系统,例如:全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(wideband code division multiple access,WCDMA)系统、通用分组无线业务(general packet radio service,GPRS)、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、先进的长期演进(advanced long term evolution,LTE-A)系统、新无线(new radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、无线局域网(wireless local area networks,WLAN)、无线保真(wireless fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(device to device,D2D)通信,机 器到机器(machine to machine,M2M)通信,机器类型通信(machine type communication,MTC),以及车辆间(vehicle to vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。

由于邻小区1支持的S-NSSAI组合中包括终端设备支持的S-NSSAI的个数最多为3,即{S-NSSAI-1,S-NSSAI-2,S-NSSAI-3}。邻小区2支持的S-NSSAI组合中包括终端设备支持的S-NSSAI个数最多为2,即{S-NSSAI-1,S-NSSAI-4};则终端设备将邻小区1作为小区重选的目标小区。
本申请实施例中,在所述候选小区的数量为一个的情况下,所述候选小区为小区重选的目标小区。在所述候选小区的数量大于一个的情况下,所述终端设备确定所述候选小区中小区参考信号接收参数最大的小区为小区重选的目标小区。其中,小区参考信号接收参数可以是小区的RSRP和/或小区的RSRQ。
本申请实施例中终端设备确定所述候选小区中小区参考信号接收参数最大的小区为小区重选的目标小区的具体实现过程,与上述实施例一中终端设备确定所述候选小区中小区参考信号接收参数最大的小区为小区重选的目标小区的具体实现过程相同,这里不再赘述。本申请实施例中,针对第一重选准则的说明与上述实施例一种针对第一重选准则的说明相同,这里不再赘述。
本申请实施例中,终端设备选择邻小区支持的S-NSSAI组合中包括终端设备支持的S-NSSAI最多的邻小区进行小区重选,能够在小区重选成功后,终端设备发起与网络切片相关的业务请求时,提高网络设备接收该业务请求的概率,提高业务传输的性能和用户体验。
