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，先对相关技术中小区切换过程进行简要说明。
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)。
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，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。
为了满足高速率的要求，5G网络也支持载波聚合(Carrier Aggregation，CA)技术。一种载波聚合的示意图，如图1所示；另一种载波聚合的示意图，如图2所示；载波聚合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NR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。根据所聚合载波在频谱上的连续性可以分为：连续性载波聚合和非连续性载波聚合；根据聚合的载波所在的band是否相同可以分为：Intra-band载波聚合和inter-band载波聚合。
聚合中的载波中存在唯一的一个主载波(Primary Component Carrier，PCC)，PCC提供无线资源控制(Radio Resource Control，RRC)信令连接、非接入层(Non-Access Stratum，NAS)功能、以及安全等。物理上行控制信道(Physical Uplink Control Channel，PUCCH)在PCC上且只在PCC上存在。聚合中的载波中还存在辅载波(Secondary Component Carrier，SCC)，SCC只提供额外的无线资源。PCC和SCC统称为服务小区。标准中规定聚合的载波最多支持5个，即聚合后的最大带宽为100MHZ，并且聚合载波属于同一个网络设备。所有的聚合载波使用相同的小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，网络设备实现C-RNTI在每个载波所在的小区不发生冲突。由于支持不对称载波聚合和对称载波聚合两种，所以要求聚合的载波一定有下行，可以没有上行。而且对于主载波小区来说一定有本小区的物理下行控制信道(Physical Downlink Control Channel，PDCCH)和PUCCH，而且只有主载波小区有PUCCH，其他辅载波小区可能有PDCCH。
在NR系统的早期部署中，完整的NR覆盖很难获取；所以典型的网络覆盖是广域的LET系统覆盖和NR系统的孤岛覆盖模式。而大量的LTE系统部署在6GHz以下的频谱，可用于5G的6GHz以上的频谱很少。所以，NR系统研究6GHz以上的频谱应用；而高频段覆盖范围有限，信号衰落快，为了保护移动运营商前期的LTE系统投资，提出了在LTE系统和NR系统之间的一种工作模式，称为tight interworking。
为了尽快实现5G网络的部署和商业应用，3GPP在2017年12底前首先完成第一个5G版本，即LTE-NR双连接(LTE-NR Dual Connectivity，EN-DC)。EN-DC的网络部署和组网架构示意图，如图3所示，LTE系统的 网络设备作为MN，NR系统的网络设备作为辅节点(Secondary Node，SN)。
在如图4所示的EN-DC场景中，MN(LTE eNB)主要用于实现RRC功能以及通向核心网(CoreNetwork，CN)的控制面，SN(gNB)可以配置辅助的信令，例如信令承载3(Signalling Radio Bearer3，SRB3)，主要提供数据传输功能。
终端设备除了EN-DC外，还支持其他的DC形式，如NE-DC、5GC-EN-DC、以及NR-DC等。EN-DC的网络架构，如图5所示，接入网络连接的核心网是EPC。NE-DC或者NR-DC的网络架构，如图6所示，NGEN-DC的网络架构，如图7所示，接入网络连接的核心网是5GC。
在Rel-15中，针对MR-DC场景，支持由MN触发的PSCell添加过程；同时支持由MN触发的PSCell更新过程和由SN触发的PSCell更新过程。PSCell的更新可以发生在同一个SN内部，也可以发生在不同的SN之间(如源SN和目标SN之间)。其中，图8为由MN触发的PSCell更新过程的示意图，图9为由SN触发的PSCell更新过程的示意图。由MN触发的PSCell更新过程中，由MN向SN发送SN更新请求(Modification Request)消息，在收到SN发送的SN更新请求确认(Modification Request Acknowledge)消息之后，发起PSCell更新。由SN触发的PSCell更新过程中，由SN向MN发送SN Modification Request消息，发起PSCell更新。
针对高速移动的场景和高频部署的场景存在频繁切换以及切换成功率地低的问题；因此引入CHO，CHO的切换流程，如图10所示，终端设备根据源网络设备发送的目标小区的配置信息和测量配置进行小区测量、配置和报告；源网络设备和目标网络设备进行切换准备；在终端设备判断满足针对目标小区的CHO的切换执行条件的情况下，终端设备按照预先配置的CHO命令(command)执行向目标小区的切换(如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性差的区域而导致的来不及或无法发送测量上报、以及无法接收到切换命令的问题。
针对MR-DC的场景，引入了基于条件触发的PSCell添加(conditional PSCell addition)和基于条件触发的PSCell更新(conditional PSCell change)；触发PSCell addition或PSCell change的节点(如MS或SN)可以通过RRC消息为终端设备配置多个候选PSCell、以及每个PSCell addition/change的执行条件。当某一个候选PSCell的PSCell addition/change的执行条件满足时，终端设备将执行PSCell addition/change过程。终端设备会向MN发送RRC重配置完成消息，所述RRC重配置完成消息中内嵌一个发送至待接入 的PSCell对应的目标SN的RRC重配置完成消息。但是，由于MN并不知道终端设备触发了向哪个PSCell的小区接入，因此MN无法把内嵌的RRC重配置完成消息发送给目标SN，也无法尽快的向目标SN进行数据转发。
本申请实施例的技术方案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。

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。
