Description

系统信息发送和接收方法、装置、设备及系统 技术领域
本公开涉及通信领域，特别涉及一种系统信息发送和接收方法、装置、设备及系统。
背景技术
在长期演进(Long-Term Evolution，LTE)中，为了支持车联网(vehicle to everything，V2X)业务，引入了基于资源池的无线资源配置方式。资源池分为发送资源池和接收资源池。发送资源池和接收资源池分别指示了用于发送和接收V2X业务的无线资源的时间和频率范围。
演进型基站(eNode B，eNB)可以在小区广播信息中广播本小区的V2X资源配置。相关技术中，eNB向小区内的各个用户终端(User Equipment，UE)广播系统信息块(System Information Block，SIB)21，UE从SIB 21中读取资源配置信息，该资源配置信息用于配置V2X数据的资源池配置。为了满足V2X业务的低时延要求，当空闲态的UE需要进行小区重选(从驻留小区切换到重选小区)时，UE可以提前读取目标小区的SIB 21，从SIB 21获取目标小区的V2X业务的资源池配置。当UE在小区重选后，UE使用提前读取到的资源池配置进行V2X业务的发送和接收，从而节省UE在小区重选后再读取SIB 21可能产生的时延。
而在5G新空口(New Redio，NR)系统中，系统信息分为最小集系统信息(minimum System Information，minimum SI)和其它系统信息(Other SI)，基站会一直广播minimum SI，并根据UE的请求选择性广播Other SI。由于5G中用于携带资源配置信息的SIB属于Other SI，而此时，UE在小区重选前无法读取到目标小区的V2X业务的资源池配置，因此无法满足V2X业务的低时延要求。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在5G技术中，系统消息分为最小集系统消息(minimum SI)和其他系统消息(Other SI)。其中，minimum SI包括主信息块(Master Information Block，MIB)和SIB 1，基站会一直广播minimum SI。而Other SI包括其他剩余的所有SIB，基站可以基于UE的请求，选择性的对Other SI中的一个或多个SIB进行广播，即当有UE发送Other SI请求之后，基站才会开始广播对应的SIB。Other SI的请求方式有两种：第一种为基于随机接入过程中的消息1(msg1)的请求方式，即基站会广播随机接入码和Other SI的对应关系，UE只需要在随机接入过程的msg 1中，发送与所要请求的SIB对应的随机接入码，基站即可获知UE所要请求的SIB。第二种为基于随机接入过程中的msg 3的请求方式，即UE需要在消息3中向基站发送系统信息请求消息，其中明确指示了UE所要请求的SIB。
示意性的，图1示出了LTE中基于竞争的随机接入过程的信令交互图，该 过程包括：
步骤01，UE随机选择一个前导序列，在随机接入信道(Random Access Channel，RACH)上向eNB发送消息1(msg 1)，使得eNB能估计其与UE之间的传输延时；
步骤02，eNB在检测到有前导序列发送后，在下行向UE发送消息2(msg2)，消息2中包括随机接入响应，随机接入响应中至少应包含以下信息，如所收到的前导序列的编号、定时调整信息、为该UE分配的上行资源位置指示信息和临时分配的C-RNTI；
步骤03，UE在收到随机接入响应后，根据其指示在分配的上行资源上发送消息3(msg 3)；
步骤04，eNB接收UE的消息3，并向接入成功的UE返回冲突解决消息4(msg 4)。
为了支持空闲态的UE进行具有低延时要求的业务，比如V2X业务、物联网(Internet of things，IoT)，5G技术将会在Other SI中引入新的SIB X，该SIB X用于携带V2X业务在发送和接收时所需的无线资源配置。在相关技术中，当小区重选中的邻小区没有广播SIB X时，UE无法在小区重选之前请求邻小区的基站广播SIB X，只能在小区重选完成之后再发送系统信息请求消息，导致在小区重选完成之后到成功接收到SIB X之前的这个时间段内，UE没有办法传输V2X业务，从而产生较大的时延，无法满足某些业务的低时延要求。示意性的，该业务是V2X业务。
本申请实施例可以解决UE无法在小区重选之前请求邻小区广播SIB X，只能在小区重选完成之后再发送系统信息请求消息来获取SIB X，从而导致无法满足某些业务的低时延要求的问题。
在本申请的实施例中，终端能够在小区重选之前，提前获取到邻小区的SIB X，终端需要通过第一基站或接入或移动性管理功能(Access and Mobility Management Function，AMF)实现向第二基站发送请求，第二基站基于该请求广播SIB X，从而使得终端能够提前接收到第二基站广播的SIB X，当终端重选完成后就可以马上使用新小区的资源池进行V2X业务。下面为本申请的两个示例性实施例提供的移动通信系统的两种架构示意图。
图2示出了本申请一个示例性实施例提供的移动通信系统的架构示意图， 图2中包括：第一接入网设备101、第二接入网设备102和终端103。
第一接入网设备101可以是终端当前驻留小区的服务基站，第二接入网设备102可以是邻小区的基站，终端103从驻留小区向邻小区的方向移动(比如车载设备从驻留小区向邻小区的方向行驶)。第一接入网设备101用于接收终端103发送的系统信息请求消息，并基于系统信息请求消息，向第二接入网设备102发送更新数据消息。第二接入网设备102用于接收第一接入网设备101发送的更新数据消息，并基于更新数据消息广播携带有SIB X的Other SI。终端103用于向第一接入网设备101发送系统信息请求消息并在第二接入网设备102广播Other SI后，接收携带有SIB X的Other SI。
图3示出了本申请另一个示例性实施例提供的移动通信系统的架构示意图，图3中包括：第一接入网设备101、第二接入网设备102、终端103和AMF104。其中，第一接入网设备101可以是终端当前驻留小区的服务基站，第二接入网设备102可以是邻小区的基站，终端103从当前驻留小区向邻小区的方向移动(比如车载设备从驻留小区向邻小区的方向行驶)，AMF104为第一接入网设备101和第二接入网设备102在核心网中的管理网元。第一接入网设备101用于接收终端103发送的系统信息请求消息，并基于系统信息请求消息，向AMF104发送第二更新数据消息。AMF104用于接收第一接入网设备101发送的第二更新数据消息，并基于第二更新数据消息，向第二接入网设备102转发第二更新数据消息，或发送第三更新数据消息。第二接入网设备102用于接收AMF104转发的第二更新数据消息，或发送的第三更新数据消息，并基于第二更新数据消息或第三更新数据消息，广播携带有SIB X的其它系统信息Other SI。终端103用于向第一接入网设备101发送系统信息请求消息，并在第二接入网设备102广播Other SI后，接收携带有SIB X的Other SI。
示意性的，本申请提供的系统信息传输方法的实施环境可以为上述两种移动通信系统中的任一种，但本实施例不做限定。上述实施环境可以是5G NR系统，终端103是支持5G NR通信协议的终端，接入网设备可以是5G NR系统中的gNB。示意性的，终端103是支持V2X业务的终端。
在本申请的一些实施例中，当邻小区没有进行广播SIB X时，终端可以通过第一基站请求第二基站广播SIB X，并接收第二基站广播的SIB X，从而能够在终端进行小区重选之前，提前获取邻小区的资源配置信息。
图4示出了本申请一个示例性实施例提供的反馈信息传输方法的流程图，该方法可以应用于图2或图3所示的移动通信系统中，本实施例以第一接入网设备是终端当前驻留小区的第一基站，第二接入网设备是邻小区的第二基站为例来举例说明，该方法包括：
步骤301，终端向第一基站发送系统信息请求消息，系统信息请求消息携带有邻小区标识和SIB X的标识，X为大于1的整数。
系统信息请求消息用于指示第一基站向第二基站发送更新数据消息，更新数据消息携带有SIB X的标识。可选地，系统信息请求消息携带在随机接入过程中的msg 3中。
SIB X携带有指定业务的无线资源配置信息。指定业务是传输延迟需求低于预设阈值的业务(也称低时延业务)。以指定业务是V2X业务为例，SIB X携带有V2X业务的资源池配置信息，该资源池配置信息包括用于发送和/或接收V2X数据的无线资源的时间和频率范围。其中，SIB X是通信协议规定的用于指示指定业务的资源池的SIB，SIB X的编号固定。也即，每个小区都是使用相同编号的SIB X来向终端提供指定业务的资源池配置信息。
可选地，邻小区标识是一个或一个以上。邻小区标识是PCI；或，邻小区标识是ECGI。
可选地，当小区广播SIB 1时，UE能够通过SIB 1接收到邻小区的ECGI；当UE与小区建立同步信息时，UE能够通过同步信息接收到邻小区的PCI。
步骤302，第一基站接收终端发送的系统信息请求消息。
可选地，第一基站接收终端发送的随机接入过程中的msg 3，从msg 3中获取系统信息请求消息。
步骤303，第一基站向第二基站发送更新数据消息，更新数据消息中携带有SIB X的标识，更新数据消息用于指示第二基站广播携带有SIB X的Other SI。
Other SI至少包括SIB X，当有UE请求SIB X后，基站会根据UE的请求广播包括SIB X的Other SI。而且基站会根据不同UE的请求广播不同的Other SI至少一个SIB X，具体SIB X的形式根据实际情况而定，这里不做限定。
当第一基站和第二基站之间存在Xn接口时，第一基站通过Xn接口向第二基站发送更新数据消息。
当第一基站和第二基站之间不存在Xn接口时，第一基站通过核心网网元 向第二基站发送更新数据消息。
其中，Xn接口用于基站间传输信令和/或数据的接口。
步骤304，第二基站接收第一基站发送的更新数据消息，更新数据消息是第一基站接收到终端发送的系统信息获取请求后发送的。
当第一基站和第二基站之间存在Xn接口时，第二基站通过Xn接口接收第一基站发送的更新数据消息。
当第一基站和第二基站之间不存在Xn接口时，第二基站接收核心网网元转发的更新数据消息。
步骤305，第二基站广播携带有SIB X的Other SI。
步骤306，终端接收第二基站广播的Other SI，Other SI携带有SIB X。
综上所述，在本实施例提供的方法中，通过UE向驻留小区的第一接入网设备发送系统信息请求消息，第一接入网设备接收该系统信息请求消息，并向邻小区的第二接入网设备发送更新数据消息，第二接入网设备在接收该更新数据消息后，广播邻小区的Other SI，该Other SI中携带有用于配置传输资源的SIB X，从而实现了UE在进行小区重选之前，能够提前读取邻小区的SIB X，从而保障了终端在传输业务数据时的低时延要求。
