具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
5G NR系统信息包括MIB以及一系列的SIB。根据系统信息中所包含的内容，可以将其分为Minimum SI以及Other SI，其中：
Minimum SI中包含了初始接入以及获取其他系统信息的基本消息，即其主要包括MIB以及SIB1。
MIB消息中包含了小区禁止状态信息以及为了获取进一步的系统消息所必要的物理层信息，如CORESET#0的配置。MIB消息承载在广播信道(Broadcast Channel，BCH)，并且周期性广播。
SIB1消息中一方面定义了其他系统消息块的调度，另一方面包含了初始接入所需要的消息。SIB1通常也叫作剩余最小系统信息(Remaining Minimum SI，RMSI)，其承载在下行共享信道(Downlink Shared Channel，DL-SCH) 上，可周期性广播或者在无线资源控制协议(Radio Resource Control，RRC)连接态RRC_CONNECTED下，通过专用信令通过DL-SCH通知UE。
Other SI涵盖了所有在Minimum SI未广播的系统消息，这些SIBs可通过以下几种方式发送：
在DL-SCH上周期性广播；
处于RRC空闲RRC_IDLE或者RRC非激活态RRC_INACTIVE态的UE请求广播；
RRC_CONNECTED态下，通过专用的方式在DL-SCH信道上发送给UE。
部分Other SI罗列如下：
SIB2包含了小区重选信息，主要是与服务小区相关；
SIB3一方面涵盖了服务小区的频率消息，另一方面包含了小区重选的同频邻区信息，主要包括小区重选的公共频率参数以及小区重选的专用参数；
SIB4一方面涵盖了其他NR频率的消息，另一方面包含了小区重选的异频邻区信息，主要包括小区重选的公共频率参数以及小区重选的专用参数；
SIB5包含了进化型的统一陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)系统频率信息，以及小区重选的E-UTRA邻区消息包括小区重选的公共频率参数以及小区重选专用参数；
SIB6包含了地震和海啸预警系统(Earthquake and Tsunami Warning System，ETWS)的主要通知信息；
SIB7包含了ETWS的辅助通过信息；
SIB8包含了商用机动警报系统(Commercial Mobile Alert System，CMAS)的通知消息；
SIB9包含了全球定位系统(Global Positioning System，GPS)时间以及协调世界时间(Coordinated Universal Time，UTC)信息。
现有的4G、5G网络每个小区广播自己的小区信息用于UE选择小区进行驻留和接入该小区，并广播小区的邻小区信息用于UE进行小区重选。这种机制下接入依赖于每个小区的接入信息，UE是先获取小区的系统信息，根据系 统信息中的配置选择驻留小区，然后使用小区系统信息中的随机接入资源发起随机接入。这就限制了每个小区都必须发送系统信息，终端的接入必须是基于每个小区的系统信息向一个小区发起的。即使多个小区是共站址或重叠覆盖，每个小区也要发送系统信息，不利于节能减排。
鉴于上述技术问题，本申请实施例提供一种终端接入联合系统信息网络的方法应用的系统的架构示意图。如图1所示，本申请实施例提供的终端接入联合系统信息网络的方法应用的系统包括网络侧设备101和UE102。
网络侧设备101，用于配置进行系统信息联合的多个小区，及配置多个小区中的至少一个小区发送联合系统信息，联合系统信息包括多个小区的信息；通过配置的发送联合系统信息的至少一个小区，发送联合系统信息给，以使UE基于联合系统信息进行小区接入。
UE102，用于在发送联合系统信息的小区，接收联合系统信息，联合系统信息包括配置的进行系统信息联合的多个小区的信息；基于联合系统信息进行小区接入。
本申请实施例中，UE具体可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户设备、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G网络中的移动台或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的订阅设备等。
网络侧设备可为5G系统中的下一代基站(generation Node B，gNB)，可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是长期演进(Long  Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)等。

示例1
如图4所示，小区(Cell)1、Cell2、Cell3、Cell4属于同一个分布式节点，Cell1工作在低频，覆盖范围包含了Cell2、Cell3、Cell4的覆盖范围。Cell1发送联合系统信息，联合系统信息中包含Cell1、Cell2、Cell3、Cell4的信息，Cell2、Cell3、Cell4不发送系统信息，但发送同步信号。
UE1在Cell1上接收系统信息，获取Cell2、Cell3、Cell4的信息，然后对Cell2、Cell3、Cell4的同步信号进行检测，满足接入条件的是Cell1和Cell2，且Cell2信号优于Cell1，UE1选择在Cell2上发起接入，使用联合系统信息中Cell2的接入配置发起接入。Cell2收到UE1的接入请求后向UE1发送响应，UE1在Cell2进入连接态。
UE2在Cell1上接收联合系统信息，获取Cell1、Cell2、Cell3、Cell4的信息，然后对Cell1、Cell2、Cell3、Cell4的同步信号进行检测，满足接入条件的是Cell1和Cell3，且Cell1信号优于Cell3，UE2选择在Cell1上发起接入，使用系统信息中Cell1的接入配置发起接入，Cell1收到UE2的接入请求后向UE2发送响应，UE2在cell1进入连接态。
示例2
本申请示例中，集中控制节点(Centralized Unit，CU)生成联合系统信息。
Cell1的分布式节点是分布式节点(Distributed Unit，DU)1，Cell2的分布式节点是DU2，Cell1和Cell2的集中控制节点都是CU，如图5所示，该方法包括：
步骤1：DU1将Cell1的信息发送给CU；
步骤2：DU2将Cell2的信息发送给CU；
步骤1和步骤2通过CU与DU间的F1接口传输；
步骤3：CU生成多小区联合系统信息，其中包含Cell1和Cell2的信息，CU将多小区联合系统信息发送给DU1；
步骤4：DU1将多小区联合系统信息发送给Cell1；
步骤5：Cell1在无线接口发送多小区联合系统信息；
步骤6(6，6a)：Cell1和Cell2周期性发送同步信号，步骤6与其他步骤之间没有时间顺序关系；
步骤7：UE基于步骤5收到的联合系统信息中的小区信息监听Cell1和Cell2的同步信号，检测到Cell2的信号质量优于Cell1，UE使用系统信息中Cell2的接入信息向Cell2发起接入请求；
步骤8：Cell2收到UE接入请求后向UE发送接入响应；
步骤9：UE发起RRC建立请求；
步骤10：CU向UE发送RRC建立响应。
示例2也可用于归属不同CU的Cell进行联合系统信息发送，每个CU 将自己的Cell信息发送给负责发送联合系统信息的Cell所在的CU，由该CU生成联合系统信息。
示例3
如图6所示，步骤4-10与示例2相同，除了联合系统信息是由DU1生成，CU只是将归属于其他DU的小区信息转发给负责发送联合系统信息的DU1。
示例3也可用于归属不同CU的Cell进行联合系统信息发送，每个CU将自己的Cell信息发送给负责发送联合系统信息的Cell所在的CU，CU再将这些小区的信息发给负责发送联合系统信息的Cell所在的DU，由该DU生成联合系统信息。
示例3也适用于DU之间存在接口的情况，非负责发送联合系统信息的Cell所在的DU将小区信息通过DU间接口直接发送给负责发送联合系统信息的Cell所在的DU，由该DU生成联合系统信息。
示例4
Cell1-4为联合系统信息发送的小区，其中Cell1发送联合系统信息，Cell2、Cell3、Cell4只发送同步信号，不发送系统信息，如图7所示，主要包括：
步骤0：UE配置或预配置了小区搜索的频率列表，在这些频点进行小区搜索，选择满足小区选择条件的Cell1进行同步。
步骤1：Cell1发送联合系统信息，UE从Cell1接收联合系统信息，获取Cell1-4的接入配置和同步信号信息。
步骤2(2，2a，2b，2c)：Cell1-4周期性发送Cell同步信号。
步骤3：UE进行同步信号检测和Cell选择，具体根据联合系统信息中的多个小区同步信号信息在对应的资源对小区进行检测或测量，基于联合系统信息中的参数对各小区进行评估并根据结果进行小区接入排序，这里假设Cell2的排序第一。
步骤4：UE使用联合系统信息中的Cell2的接入配置在Cell2上发起接入请求。
步骤5：UE根据联合系统信息中的Cell2的接入响应配置接收Cell2的接 入响应。
步骤6：UE与Cell2之间建立控制面和/或用户面连接。
