Description

一种消息发送方法及设备 技术领域
本申请涉及通信技术领域，尤其涉及一种消息发送方法及设备。
背景技术
当前运营商对于第五代移动通信技术(the 5th generation，5G)演进的路线有两种选择，一种是采用非独立(non standalone，NSA)布网方式，即当前支持第四代移动通信技术(the 4th generation，4G)的基站为连接演进分组核心网(evolved packet core，EPC)的演进型基站(evolutional Node B，eNodeB)，运营商通过部署连接EPC的下一代节点B(next generation node B，gNB)，让gNB作为eNB的辅站，提供5G的空口服务。另一种是采用独立(standalone，SA)布网方式，直接部署连接5G核心网(5GC)的gNB。
从运营商当前考虑的布网场景来看，可能会出现NSA布网方式及SA布网方式同时布网的可能性。例如考虑到当前4G网络的覆盖，采用NSA的布网方式，为增强移动宽带(enhance mobile broadband，eMBB)业务的终端设备提供5G服务；而针对一些新5G应用场景，如工业网络，企业网等，提供的业务(如超高可靠低时延通信(ultra reliable&low latency communication，URLLC)或海量机器类通信(massive machine type of communication，mMTC)等)需要切片(slicing)支持，进行SA的部署，即部署连接5G核心网的新无线(new radio，NR)基站。
当运营商存在两种布网情况时，对于终端设备来说，如果移动到5G网络和4G网络的重复覆盖区域，也就是SA布网方式和NSA布网方式的重复覆盖区域，则终端设备会优先接入按照SA布网方式部署的5G网络中。而运营商在按照SA布网方式部署5G网络时，可能5G网络下的一些基站只能提供特定业务，例如只提供URLLC业务。如果驻留的终端设备需要的是其他业务，例如需要eMBB业务，则该基站无法提供，导致终端设备无法直接发起服务请求，进行正常工作，用户体验极差。
发明内容
本申请实施例提供一种消息发送方法及设备，用于使得终端设备能够正常工作。
第一方面，提供第一种消息发送方法，该方法包括：生成第一消息，所述第一消息包括K个指示信息，所述K个指示信息与M个第一信息相对应，所述K个指示信息中的每个指示信息对应一种或多种业务，所述每个指示信息用于指示所述M个第一信息中的一个第一信息是否支持所述一种或多种业务，所述第一信息为小区信息或频率信息，M为正整数，K为大于或等于M的整数；在第一小区发送所述第一消息。
该方法可由第一通信装置执行，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，例如芯片系统。这里以第一通信装置是网络设备为例。
在本申请实施例中，第一消息可以包括K个指示信息，每个指示信息可以指示一个小区或一个频率是否支持一种或多种业务，终端设备在接收第一消息后就可以确定相应的小区或频率是否支持相应的业务，从而终端设备可以选择不驻留到这些小区或频率，或者如果终端设备已经处在该小区或频率下，终端设备也可以通过小区重选等方式接入其他的小区或频率。通过这种方式，使得终端设备可以选择接入能够提供终端设备所需的业务的小区或频率，从而终端设备可以正常工作，提升用户体验。对于网络 设备来说，所提供的业务能够被终端设备所应用，也提高了资源的利用率。
结合第一方面，在第一方面的第一种可能的实施方式中，所述一种或多种业务包括如下的至少一种：URLLC业务、eMBB业务、mMTC业务。
例如，一种或多种业务具体为一种业务，那么该业务可以是URLLC业务、或eMBB业务、或mMTC业务、或V2X业务，或者还可以是除了这四种业务之外的其他业务；或者，一种或多种业务具体为多种业务，那么该多种业务可以包括URLLC业务和eMBB业务，或者包括URLLC业务和mMTC业务，或者包括eMBB业务和mMTC业务，或者包括URLLC业务、eMBB业务和mMTC业务，或者包括URLLC业务和V2X业务，或者包括eMBB业务和V2X业务，或者包括mMTC业务和V2X业务，或者包括URLLC业务、eMBB业务和V2X业务，或者包括URLLC业务、mMTC业务和V2X业务，或者包括mMTC业务、eMBB业务和V2X业务，或者包括URLLC业务、eMBB业务、V2X业务和mMTC业务，或者可以不包括这四种业务，而是包括除了这四种业务之外的其他的业务，或者可以包括这四种业务中的至少一种，以及包括除了这四种业务之外的其他业务，例如包括URLLC业务和V2X业务，以及包括除了这四种业务之外的其他业务。
结合第一方面或第一方面的第一种可能的实施方式，在第一方面的第二种可能的实施方式中，所述K个指示信息中的每个指示信息用于指示一个相邻的小区或一个相邻的频率是否支持一种或多种业务。
例如，目前网络设备会通过系统消息发送邻区信息，那么可以在邻区信息中增加K个指示信息，K个指示信息对应于邻区信息中的M个邻区信息，K个指示信息就用于指示M个邻区信息中的每个邻区信息是否支持相应的业务，M个邻区信息中的一个邻区信息可以对应一个或多个指示信息。或者，目前网络设备会通过系统消息发送邻频信息，那么可以在邻频信息中增加K个指示信息，K个指示信息对应于邻频信息中的M个邻频信息，K个指示信息就用于指示M个邻频信息中的每个邻频信息是否支持相应的业务，M个邻频信息中的一个邻频信息可以对应一个或多个指示信息。这样，终端设备在进行小区重选或小区切换时，可以根据K个指示信息尽量重选或切换到能够支持终端设备所需的业务的小区，使得终端设备能够正常工作。
结合第一方面或第一方面的第一种可能的实施方式，在第一方面的第三种可能的实施方式中，所述指示信息用于指示所述第一小区是否支持一种或多种业务。
第一小区例如为终端设备的服务小区，K个指示信息可以指示第一小区是否支持一种或多种业务，从而终端设备可以根据K个指示信息确定第一小区是否支持终端设备所需的业务，如果不支持，终端设备可以考虑重选或切换到其他小区，以使得终端设备能够正常进行所需的业务。
结合第一方面或第一方面的第一种可能的实施方式或第一方面的第三种可能的实施方式，在第一方面的第四种可能的实施方式中，包括如下至少一种：
所述K个指示信息中的一个指示信息包括N比特，所述N比特用于指示所述第一小区是否支持N种业务，其中，每个比特用于指示一种业务，N为正整数；或，
所述K个指示信息中的一个指示信息包括H比特，所述H比特用于指示所述第一小区是否支持N种业务，其中，每个比特用于指示一种或多种业务，H为正整数，N为大于或等于2的整数，且H小于N。
例如，可以通过一个比特指示一种业务，这种指示方式较为明确，通过指示信息包括的不同的比特就可以确定第一小区是否支持相应的业务。或者，也可以通过一个比特指示多种业务，这样通过较少的比特就能够指示较多种业务，在完成指示任务的同时也能减少指示信息的比特数，有助于节省信令开销。
结合第一方面或第一方面的第一种可能的实施方式至第一方面的第四种可能的实施方式中的任一 种可能的实施方式，在第一方面的第五种可能的实施方式中，所述方法还包括：在所述第一小区发送第二消息，所述第二消息包括对应于所述M个第一信息的时间信息，其中，所述时间信息包括如下至少一种：
所述时间信息中的一个时间信息与所述K个指示信息中的一个指示信息对应，所述一个时间信息用于指示所述一个指示信息所对应的第一信息在一个时间段内支持与所述一个指示信息对应的一种或多种业务；或，
所述时间信息中的一个时间信息与一种业务对应，以及所述一个时间信息与一个第一信息对应，所述一个时间信息用于指示所述一个第一信息在一个时间段内支持所述一种业务，所述一种业务属于所述一个第一信息所对应的指示信息对应的业务；或，
所述时间信息中的一个时间信息与所述K个指示信息中的一个指示信息对应，所述一个时间信息用于指示所述一个指示信息所对应的第一信息在一个时间段内不支持与所述一个指示信息对应的一种或多种业务；或，
所述时间信息中的一个时间信息与一种业务对应，以及所述一个时间信息与一个第一信息对应，所述一个时间信息用于指示所述一个第一信息在一个时间段内不支持所述一种业务，所述一种业务属于所述一个第一信息所对应的指示信息对应的业务。
对于一个小区或频率来说，在有些情况下，可能是一段时间内支持某种业务，而在另一段时间内不支持该业务，例如一个小区本来支持URLLC业务和eMBB业务，而在一段时间内可能该小区对于URLLC业务的要求较高，那么在这段时间该小区可能会停止支持eMBB业务，而只支持URLLC业务，但在这段时间过后，该小区又可以恢复支持eMBB业务。因此本申请实施例考虑到小区或频率的这一特性，为相应的指示信息或业务添加时间信息，从而为一个小区或一个频率支持或不支持相应的业务添加一个时限，在该时限内该小区或频率支持相应的业务，在该时限外该小区或频率不支持相应的业务，或者在该时限内该小区或频率不支持相应的业务，在该时限外该小区或频率支持相应的业务，使得对于小区是否支持某些业务的指示更符合实际情况。
结合第一方面，或第一方面的第一种可能的实施方式，或第一方面的第三种可能的实施方式至第一方面的第五种可能的实施方式中的任一种可能的实施方式，在第一方面的第六种可能的实施方式中，所述方法还包括：在所述第一小区发送SIB1消息，其中，所述SIB1中的cellreservedforotheruse字段用于指示拒绝终端设备驻留。
对于老版本的终端设备来说，可能无法识别本申请实施例所提供的指示信息，因此可能无法根据本申请实施例的方案确定相应的小区或频率是否支持相应的业务，鉴于此，可以考虑只将本申请实施例提供的技术方案用于新版本的终端设备。那么对于老版本的终端设备来说，由于无法识别本申请实施例提供的指示信息，则还是很有可能会接入到并不支持该终端设备所需的业务的小区，从而导致无法正常工作。为此，网络设备还可以在第一小区发送系统消息，例如为SIB1，该SIB1中的cellreservedforotheruse字段可以用于指示拒绝终端设备驻留。终端设备接收来自网络设备的SIB1后，如果该终端设备是老版本的终端设备，则可以根据cellreservedforotheruse字段确定第一小区是拒绝驻留的，从而该终端设备可以不驻留在第一小区，而是重新选择驻留到其他小区。在这种情况下，无论第一小区是否能够提供老版本的终端设备所需要的业务，都会拒绝老版本的终端设备驻留，而即使第一小区能够提供老版本的终端设备所需要的业务，第一小区拒绝驻留，终端设备可以继续选择其他的小区，照样可以在其他小区正常工作，而本申请实施例这样处理，可以尽量减少终端设备驻留在不能提供所需的业务的小区的概率。
结合第一方面或第一方面的第一种可能的实施方式至第一方面的第六种可能的实施方式中的任一 种可能的实施方式，在第一方面的第七种可能的实施方式中，所述第一消息为SIB和/或MIB。
具体的，第一消息为SIB或MIB，或第一消息为SIB和MIB。本申请实施例对于第一消息的实现方式不做限制。
结合第一方面或第一方面的第一种可能的实施方式至第一方面的第七种可能的实施方式中的任一种可能的实施方式，在第一方面的第八种可能的实施方式中，所述第一消息为MIB，所述MIB的cellbarred的比特用于所述K个指示信息，和/或，所述MIB中的最后的比特用于所述K个指示信息。
如果第一消息是MIB，那么这里给出了第一消息通过MIB实现的可能的方式，具体的不限于此。
第二方面，提供第一种消息接收方法，该方法包括：接收来自网络设备的第一消息；根据所述第一消息包括的K个指示信息，确定M个第一信息中的每个第一信息是否支持相应的业务，其中，所述K个指示信息中的每个指示信息对应一种或多种业务，所述每个指示信息用于指示所述M个第一信息中的一个第一信息是否支持所述一种或多种业务，所述第一信息为小区信息或频率信息，M为正整数，K为大于或等于M的整数。
该方法可由第二通信装置执行，第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，例如芯片系统。这里以第一通信装置是终端设备为例。
结合第二方面，在第二方面的第一种可能的实施方式中，所述一种或多种业务包括如下的至少一种：URLLC业务、eMBB业务、mMTC业务、V2X业务。

为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备，包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、车连接一切(vehicle to everything，V2X)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
2)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，或者例如，一种V2X技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络设备可以包括LTE系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G NR系统中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。

以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一消息和第二消息，只是为了区分不同的消息，而并不是表示这两种消息的内容、优先级、发送顺序或者重要程度等的不同。
如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术特征。
当前运营商对于5G演进的路线有两种选择，一种是采用NSA布网方式，即当前支持4G的基站为连接EPC的eNodeB，运营商通过部署连接EPC的gNB，让gNB作为eNB的辅站，提供5G的空口服务。另一种是采用SA布网方式，直接部署连接5GC的gNB。对于SA布网方式，还可以支持一些5G的新应用场景，例如切片，可以理解为替花钱的用户提供专用资源，可以为用户提供更好的服务质量(quality of service，QoS)。
从运营商当前考虑的布网场景来看，可能会出现NSA布网方式及SA布网方式同时布网的可能性。例如考虑到当前4G网络的覆盖，采用NSA的布网方式，为eMBB业务的终端设备提供5G服务；而针对一些新5G应用场景，如工业网络，企业网等，提供的业务(如URLLC或mMTC等)需要切片支持，进行SA的部署，即部署连接5G核心网的NR基站。
可参考图1，为两种布网方式同时部署的示意图。例如4G网络可以提供普通场景下的eMBB业务，5G网络可以提供多适用于工业场景的URLLC业务和mMTC业务。图1中，4G网络为NSA布网方式，网络设备1和网络设备2均表示eNB，网络设备3表示连接EPC的gNB，5G网络为SA布网方式，网络设备4和网络设备5均表示直接连接5GC的gNB。
当前的SA布网方式下，基站可以通过广播系统信息，对终端设备进行拒绝接入或者进行接入控制。基站广播的系统信息包括主信息块(master information block，MIB)和系统信息块(system information block，SIB)。其中，终端设备通过读取MIB，可以获取SIB1的读取位置，通过读取SIB1，可以获取其他SIB的读取位置。
基站对终端设备拒接接入，主要可以通过以下方式实现：
通过设置MIB中的小区禁止(cellbarred)，可以拒绝所有终端设备驻留。
cellbarred的取值可以设置为禁止(barred)或不禁止(not barred)，如果将cellbarred的取值可以设置为barred，该小区就会对所有的终端设备拒绝接入。
2、在SIB1中包括小区接入相关信息(cellaccessrelatedinfo)，在cellaccessrelatedinfo中包含小区预留为其他用途(cellreservedforotheruse)，可以通过设置cellreservedforotheruse的取值，使得该小区拒绝所有的终端设备驻留。
而接入控制是指，对已经驻留在当前小区的终端设备，基站可以通过SIB1中的uac-BarringInfo，提供关于公共陆地移动网络(public land mobile network，PLMN)及访问范畴(access category，AC)的相关信息，终端设备根据相关信息，依概率决定是否发起业务请求，以及发起业务请求的频率。一个简单的例子是，如果终端设备属于中国移动(这是PLMN)的动感地带(这是运营商定义的一种AC)，在某个小区比较繁忙时，例如该小区为演唱会地点，在举行演唱会时该小区就较为繁忙，则基站会限制这类终端设备发起业务，会给这类终端设备设置一定的概率不让其发起业务。例如给这类终端设备配置一个门限，该门限的取值范围例如为[0,1]，这类终端设备如果想发起业务(例如打电话等)，则需要掷色子，随机掷出0到1的随机数，当掷出的随机数小于基站配置的门限时该终端设备才能发起随机接入，如果掷出的随机数大于门限，则需启动一个定时器，在该定时器超时时终端设备才能再次掷色子。通过 这种方式可以控制驻留在当前小区的终端设备发起业务请求的频率。
当运营商存在两种布网情况时，对于终端设备来说，如果移动到5G网络和4G网络的重复覆盖区域，也就是SA布网方式和NSA布网方式的重复覆盖区域，则终端设备会优先接入按照SA布网方式部署的5G网络中。而运营商在按照SA布网方式部署5G网络时，可能5G网络下的一些基站只能提供特定业务，例如只提供URLLC业务，而如果该基站按照现有技术中的方式拒绝终端设备驻留，则会拒绝所有的终端设备驻留，但是该基站又需要向一些终端设备提供服务，因此不能选择拒绝终端设备驻留。如果驻留的终端设备需要的是其他业务，例如需要eMBB业务，则该基站无法提供，导致终端设备无法正常工作。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，例如网络设备可以发送第一消息，第一消息可以包括K个指示信息，每个指示信息可以指示一个小区或一个频率是否支持一种或多种业务，终端设备在接收第一消息后就可以确定相应的小区或频率是否支持相应的业务，从而终端设备可以选择不驻留到这些小区或频率，或者如果终端设备已经处在该小区或频率下，终端设备也可以通过小区重选等方式接入其他的小区或频率。通过这种方式，使得终端设备可以选择接入能够提供终端设备所需的业务的小区或频率，从而终端设备可以正常工作。对于网络设备来说，所提供的业务能够被终端设备所应用，也提高了资源的利用率。
本申请实施例提供的技术方案可以用于4G系统，例如LTE系统，或5G系统，例如NR系统，或者还可以应用于下一代移动通信系统或其他类似的通信系统，具体的不做限制。
请参见图2，为本申请实施例的一种应用场景。在图2中包括一个网络设备以及一个终端设备。其中，该网络设备例如工作在演进的通用移动通信系统陆地无线接入(evolved UMTS terrestrial radio access，E-UTRA)系统中，或者工作在NR系统中。该网络设备可以是NSA和SA两种布网方式同时存在时的任意一个NSA下的网络设备或任意一个SA下的网络设备，或者也可能是只存在NSA时的一个NSA下的网络设备，或者也可能是只存在SA时的一个SA下的网络设备。当然，在本申请实施例中，一个网络设备可以服务于多个终端设备，图2只是以其中的一个终端设备为例。
图2中的网络设备例如为基站。其中，网络设备在不同的系统对应不同的设备，例如在4G系统中可以对应eNB，在5G系统中对应5G中的网络设备，例如gNB。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供第一种消息发送、接收方法，请参见图3，为该方法的流程图。在下文的介绍过程中，以该方法应用于图2所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。对于第二通信装置也是同样，第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制，例如第一通信装置可以是网络设备，第二通信装置是终端设备，或者第一通信装置和第二通信装置都是网络设备，或者第一通信装置和第二通信装置都是终端设备，或者第一通信装置是网络设备，第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置，等等。其中，网络设备例如为基站。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端设备为例。如果将本实施例应用在图2所示的网络架构，下文中所述的 用于执行图3所示的实施例的网络设备可以是图2所示的网络架构中的网络设备，下文中所述的终端设备可以是图2所示的网络架构中的终端设备。
S31、网络设备生成第一消息，所述第一消息包括K个指示信息，所述K个指示信息与M个第一信息相对应，所述K个指示信息中的每个指示信息对应一种或多种业务，所述每个指示信息用于指示所述M个第一信息中的一个第一信息是否支持所述一种或多种业务，所述第一信息为小区信息或频率信息，M为正整数，K为大于或等于M的整数。
例如，K个指示信息中的每个指示信息可以对应一个第一信息，而M个第一信息中的每个第一信息可以对应一个或多个指示信息。一个指示信息可以对应一种或多种业务，因为指示信息用于指示M个第一信息中的一个第一信息是否支持一种或多种业务，因此，指示信息“对应”一种或多种业务，可以理解为是“指示”一种或多种业务，也就是指示第一信息是否支持这一种或多种业务。在本申请实施例中，一种或多种业务可以包括如下的至少一种：URLLC业务、eMBB业务、mMTC业务、V2X业务。例如，一种或多种业务具体为一种业务，那么该业务可以是URLLC业务、或eMBB业务、或mMTC业务、或V2X业务，或者还可以是除了这四种业务之外的其他业务；或者，一种或多种业务具体为多种业务，那么该多种业务可以包括URLLC业务和eMBB业务，或者包括URLLC业务和mMTC业务，或者包括eMBB业务和mMTC业务，或者包括URLLC业务、eMBB业务和mMTC业务，或者包括URLLC业务和V2X业务，或者包括eMBB业务和V2X业务，或者包括mMTC业务和V2X业务，或者包括URLLC业务、eMBB业务和V2X业务，或者包括URLLC业务、mMTC业务和V2X业务，或者包括mMTC业务、eMBB业务和V2X业务，或者包括URLLC业务、eMBB业务、V2X业务和mMTC业务，或者可以不包括这四种业务，而是包括除了这四种业务之外的其他的业务，或者可以包括这四种业务中的至少一种，以及包括除了这四种业务之外的其他业务，例如包括URLLC业务和V2X业务，以及包括除了这四种业务之外的其他业务。
作为指示信息的第一种指示方式，K个指示信息中的每个指示信息可以用于指示当前的小区是否支持一种或多种业务。当前的小区，可以是指网络设备发送第一消息的小区，也就是网络设备将在当前的小区发送第一消息。或者，本文中也可以将当前的小区称为第一小区。此时M可以是1，且第一信息可以是小区信息。
例如，K的数量可以与需指示的业务的数量相等，例如需指示的业务的数量为N，N为正整数，K＝N。例如N＝4，这4种业务分别为URLLC业务、eMBB业务、mMTC业务和V2X业务，那么K也可以等于4，则第一小区可以对应4个指示信息，这4个指示信息分别为指示信息1、指示信息2、指示信息3和指示信息4。指示信息和需指示的业务一一对应，例如这4个指示信息中的指示信息1与URLLC业务对应，指示信息2与eMBB业务对应，指示信息3与mMTC业务对应，指示信息4与V2X业务对应。指示信息1用于指示第一小区是否支持URLLC业务，指示信息2用于指示第一小区是否支持eMBB业务，指示信息3用于指示第一小区是否支持mMTC业务，指示信息4用于指示第一小区是否支持V2X业务。例如K个指示信息中的每个指示信息可以为1比特(bit)，以指示信息1为例，例如指示信息1的1比特的取值为“1”，表明第一小区支持URLLC业务，或者指示信息1的1比特的取值为“0”，表明第一小区不支持URLLC业务；或者，这1比特的取值可以是“1”或“0”，只要网络设备发送了指示信息1，就表明第一小区支持URLLC业务，而如果网络设备不发送指示信息1，表明第一小区不支持URLLC业务。其他的指示信息的指示方式都是类似的。指示信息和需指示的业务一一对应，可以使得指示更为明确。
或者，K的数量也可以小于需指示的业务的数量，例如需指示的业务的数量为N，则K<N。例如 N＝4，这4种业务分别为URLLC业务、eMBB业务、mMTC业务和V2X业务，那么K可以小于4，例如K＝1，则第一小区可以对应一个指示信息，这一个指示信息可以用于指示4种业务。例如，该指示信息包括的比特数可以等于需指示的业务的数量，例如需指示的业务的数量N为4，那么该指示信息也可以包括4比特，其中的一个比特就用于指示一种业务，指示信息包括的比特和需指示的业务一一对应。例如这4个比特中的第一个比特用于指示第一小区是否支持URLLC业务，第二个比特用于指示第一小区是否支持eMBB业务，第三个比特用于指示第一小区是否支持mMTC业务，第四个比特用于指示第一小区是否支持V2X业务。以第一个比特为例，例如第一个比特的取值为“1”，表明第一小区支持URLLC业务，或者第一个比特的取值为“0”，表明第一小区不支持URLLC业务；或者，第一个比特的取值可以是“1”或“0”，只要指示信息包括第一个比特，就表明第一小区支持URLLC业务，而如果指示信息不包括第一个比特，也就是网络设备不发送第一个比特，表明第一小区不支持URLLC业务。指示信息包括的其他的比特的指示方式都是类似的。其中，第一个比特可以是指最高位的比特，或者是最低位的比特，或者是任意位置的比特，具体的不做限制。指示信息包括的比特和需指示的业务一一对应，可以使得指示更为明确。
或者，K的数量小于需指示的业务的数量，例如N＝4，K＝1，这一个指示信息包括的比特数也可以小于需指示的业务的数量。例如，该指示信息可以包括H比特，H为正整数，H<N，既然H<N，此时N可以是大于或等于2的整数，那么H比特中的每个比特可以用于指示一种或多种业务。例如，这4种业务分别为URLLC业务、eMBB业务、mMTC业务和V2X业务，该指示信息例如包括2比特，其中的第一个比特用于指示第一小区是否支持URLLC业务和eMBB业务，其中的第二个比特用于指示第一小区是否支持mMTC业务和V2X业务。其中，第一个比特可以是指2个比特中最高位的比特，或者是最低位的比特，具体的不做限制。以第一个比特为例，例如这1比特的取值为“1”，表明第一小区支持URLLC业务和eMBB业务，或者这1比特的取值为“0”，表明第一小区不支持URLLC业务和eMBB业务；或者，这1比特的取值可以是“1”或“0”，只要指示信息包括了这1比特，就表明第一小区支持URLLC业务和eMBB业务，而如果指示信息不包括这1比特，也就是网络设备未发送这1比特，表明第一小区不支持URLLC业务和eMBB业务；或者，这1比特的取值为“1”，表明第一小区支持URLLC业务，或者这1比特的取值为“0”，表明第一小区不支持eMBB业务，等等。对于第二个比特的指示方式也是类似的。通过一个比特指示较多的业务，有助于节省比特开销。
或者，K的数量小于需指示的业务的数量，K个指示信息中的每个指示信息包括的比特数也可以小于需指示的业务的数量，但是K个指示信息总共包括的比特数等于需指示的业务的数量。例如，N＝4，这4种业务分别为URLLC业务、eMBB业务、mMTC业务和V2X业务，K＝2，第一小区对应两个指示信息，分别为指示信息1和指示信息2。其中指示信息1包括2比特，以及指示信息2也包括2比特，可见，两个指示信息总共包括的比特数等于需指示的业务的数量，那么指示信息包括的比特与需指示的业务可以是一一对应的关系，则指示信息对于业务的指示方式可以参考前文的类似介绍。
或者，K的数量小于需指示的业务的数量，K个指示信息中的每个指示信息包括的比特数也可以小于需指示的业务的数量，且K个指示信息总共包括的比特数也小于需指示的业务的数量。例如，N＝4，这4种业务分别为URLLC业务、eMBB业务、mMTC业务和V2X业务，K＝2，第一小区对应两个指示信息，分别为指示信息1和指示信息2。其中指示信息1包括2比特，以及指示信息2包括1比特，可见，两个指示信息总共包括的比特数小于需指示的业务的数量，那么可以通过两个指示信息包括的至少一个比特中的每个比特指示至少两种业务。例如，可以通过指示信息1包括的第一个比特指示第一小区是否支持URLLC业务，通过指示信息1包括的第二个比特指示第一小区是否支持eMBB业务，通过 指示信息2包括的1个比特指示第一小区是否支持mMTC业务和V2X业务。关于这几个比特的具体指示方式，可以参考前文的类似介绍。
作为指示信息的第二种指示方式，K个指示信息中的每个指示信息可以用于指示当前的小区的频率是否支持一种或多种业务。此时M可以是1，且第一信息可以是频率信息。指示信息具体的指示方式可以参考前文中当第一信息是小区信息时的介绍，指示方式都是类似的，只是将前文中的“第一小区”替换为“第一小区的频率”即可。
作为指示信息的第三种指示方式，K个指示信息中的每个指示信息可以用于指示一个相邻的小区是否支持一种或多种业务。
目前网络设备会通过系统消息发送邻区信息，那么可以在邻区信息中增加K个指示信息，K个指示信息对应于邻区信息中的M个邻区信息，K个指示信息就用于指示M个邻区信息中的每个邻区信息是否支持相应的业务，M个邻区信息中的一个邻区信息可以对应一个或多个指示信息。M小于或等于网络设备发送的邻区信息中所包括的邻区的数量。
例如，可以为M个邻区信息中的每个邻区信息添加一个指示信息，此时K＝M。对于一个指示信息来说，该指示信息包括的比特的数量可以等于该指示信息对应的邻区信息所支持的业务的数量，或者等于需指示的业务的数量。例如需指示的业务为URLLC业务、eMBB业务和V2X业务，那么可以为每个邻区信息添加一个指示信息，每个指示信息包括3比特，3比特和3种业务一一对应。对于每个指示信息具体的指示方式，可参考前文中的类似介绍。
或者，可以为M个邻区信息中的每个邻区信息添加一个指示信息，对于一个指示信息来说，该指示信息包括的比特的数量可以小于该指示信息对应的邻区信息所支持的业务的数量，或者小于需指示的业务的数量。例如需指示的业务为URLLC业务、eMBB业务和V2X业务，那么可以为每个邻区信息添加一个指示信息，每个指示信息包括的比特数小于3，不同的指示信息包括的比特数可以相同，或者也可以不同。例如需指示的业务为URLLC业务、eMBB业务和V2X业务，那么可以为每个邻区信息添加一个指示信息，例如其中的每个指示信息都包括2比特，这2个比特中的第一个比特用于指示对应的邻区信息是否支持URLLC业务和eMBB业务，这2个比特中的第二个比特用于指示对应的邻区信息是否支持V2X业务。关于指示信息具体的指示方式可参考前文中的类似介绍。
或者，可以为M个邻区信息中的每个邻区信息添加一个指示信息，对于一个指示信息来说，该指示信息包括的比特的数量可以小于或等于需指示的业务的数量，不同的邻区信息对应的指示信息所包括的比特的数量可以相同也可以不同。例如需指示的业务为URLLC业务、eMBB业务和V2X业务，那么可以为每个邻区信息添加一个指示信息，其中的一部分指示信息中的每个指示信息包括的比特数等于3，剩余的指示信息中的每个指示信息包括的比特数小于3，且对于剩余的指示信息，不同的指示信息包括的比特数可以相同也可以不同，例如剩余的指示信息中的每个指示信息都可以包括1比特，或者剩余的指示信息中的第一部分指示信息中的每个指示信息包括的比特数为1，剩余的指示信息中的第二部分指示信息中的每个指示信息包括的比特数为2。
例如需指示的业务为URLLC业务、eMBB业务、mMTC业务和V2X业务，那么可以为每个邻区信息添加一个指示信息。例如其中的一部分指示信息中的每个指示信息包括4比特，4比特和4种业务一一对应。对于每个指示信息具体的指示方式，可参考前文中的类似介绍。其中的剩余的指示信息中的每个指示信息包括的比特数小于4，例如其中的剩余的指示信息中的每个指示信息包括2比特，例如这2个比特中的第一个比特用于指示对应的邻区信息是否支持URLLC业务和eMBB业务，这2个比特中的第二个比特用于指示对应的邻区信息是否支持mMTC业务和V2X业务，具体的比特指示方式可以参 考前文的类似介绍；或者，其中的剩余的指示信息中的第一部分指示信息中的每个指示信息包括2比特，这2个比特中的第二个比特用于指示对应的邻区信息是否支持mMTC业务和V2X业务，剩余的指示信息中的第二部分指示信息中的每个指示信息包括3比特，这3个比特中的第一个比特用于指示对应的邻区信息是否支持URLLC业务和eMBB业务，这3个比特中的第二个比特用于指示对应的邻区信息是否支持mMTC业务，这3个比特中的第三个比特用于指示对应的邻区信息是否支持V2X业务，具体的比特指示方式可以参考前文的类似介绍。
或者，可以为M个邻区信息中的每个邻区信息添加多个指示信息，此时K>M。其中的每个指示信息包括的比特的数量可以小于该指示信息对应的邻区信息所支持的业务的数量，或者小于需指示的业务的数量，但对于每个邻区信息来说，该邻区信息对应的所有的指示信息所包括的比特数的总和等于需指示的业务的数量，那么指示信息包括的比特和需指示的业务可以是一一对应的，具体的比特指示方式可以参考前文的类似介绍。
或者，可以为M个邻区信息中的每个邻区信息添加多个指示信息，此时K>M。其中的每个指示信息包括的比特的数量可以小于该指示信息对应的邻区信息所支持的业务的数量，或者小于需指示的业务的数量，且对于M个邻区信息中的至少一个邻区信息来说，至少一个邻区信息中的每个邻区信息对应的所有的指示信息所包括的比特数的总和小于需指示的业务的数量。例如，M个邻区信息中的每个邻区信息对应的所有的指示信息所包括的比特数的总和小于需指示的业务的数量，或，M个邻区信息中的部分邻区信息中的每个邻区信息对应的所有的指示信息所包括的比特数的总和等于需指示的业务的数量，M个邻区信息中的剩余的邻区信息中的每个邻区信息对应的所有的指示信息所包括的比特数的总和小于需指示的业务的数量。对于一个邻区信息来说，如果该邻区信息对应的所有的指示信息所包括的比特数的总和等于需指示的业务的数量，那么具体的指示方式可以参考前文的类似介绍。对于一个邻区信息来说，如果该邻区信息对应的所有的指示信息所包括的比特数的总和小于需指示的业务的数量，那么具体的指示方式可以参考前文的类似介绍。
作为指示信息的第四种指示方式，K个指示信息中的每个指示信息可以用于指示一个相邻的频率是否支持一种或多种业务。其中，相邻的频率也可以称之为邻频，是指与第一小区的相邻的小区所在的频率。
目前网络设备会通过系统消息发送邻频信息，那么可以在邻频信息中增加K个指示信息，K个指示信息对应于邻频信息中的M个邻频信息，K个指示信息就用于指示M个邻频信息中的每个邻频信息是否支持相应的业务，M个邻频信息中的一个邻频信息可以对应一个或多个指示信息。M小于或等于网络设备发送的邻频信息中所包括的邻频的数量。
指示信息具体的指示方式可以参考前文中当第一信息是邻区信息时的介绍，指示方式都是类似的，只是将前文中的“邻区信息”替换为“邻频信息”即可。
第一消息可以是系统消息，例如系统信息块(system information blocks，SIB)和/或主信息块(master information block，MIB)，具体的不做限制。
例如第一消息为MIB，那么可以将MIB包括的cellbarred的比特用作K个指示信息，相当于改变了cellbarred所指示的含义，将cellbarred用作K个指示信息，指示M个第一信息中的每个第一信息是否支持相应的业务。其中，K个指示信息可以全部通过cellbarred包括的比特实现，或者，K个指示信息中的部分指示信息可以通过cellbarred包括的比特实现，而K个指示信息中剩余的指示信息还需通过其他方式实现，例如通过MIB中的其他比特实现，或者可以携带在SIB中，如果K个指示信息中剩余的指示信息携带在MIB中，那么第一消息就包括SIB和MIB。例如第一消息包括的K个指示信息用于 指示第一小区是否支持一种或多种业务，该K个指示信息可以通过MIB包括的cellbarred实现，用于指示第一小区是否支持一种或多种业务。具体如何指示可参考前文中的类似介绍。
或者，也可以将MIB中的空闲(spare)比特加以利用，将其用作K个指示信息。例如，目前MIB中的空闲比特为1比特，这1比特是MIB中的位于最后的比特，那么可以将这1比特用作K个指示信息。其中，K个指示信息可以全部通过MIB中的空闲比特实现，或者，K个指示信息中的部分指示信息可以通过MIB中的空闲比特实现，而K个指示信息中剩余的指示信息还需通过其他方式实现，例如通过MIB中的其他比特实现(例如通过cellbarred实现)，或者可以携带在SIB中，如果K个指示信息中剩余的指示信息携带在MIB中，那么第一消息就包括SIB和MIB。例如第一消息包括的K个指示信息用于指示第一小区是否支持一种或多种业务，该K个指示信息可以通过MIB中的空闲比特实现，该空闲比特例如为1比特，例如，如果这1比特的取值为“1”，表明第一小区支持V2X业务，如果这1比特的取值为“0”，表明第一小区支持URLLC业务、eMBB业务和mMTC业务；或者，如果这1比特的取值为“1”，表明第一小区支持URLLC业务、eMBB业务、V2X业务和mMTC业务，如果这1比特的取值为“0”，表明第一小区不支持URLLC业务、eMBB业务、V2X业务和mMTC业务。对于具体的指示方式不做限制。
另外，在如上的介绍中，如果一个指示信息(或者说一个或多个比特)用于指示一个小区或一个频率是否支持一种业务，都是显式指示。例如通过一个指示信息中的一个比特来指示第一信息是否支持URLLC业务，指示方式可以是，如果这1比特的取值为“1”，表明第一信息支持URLLC业务，而如果这1比特的取值为“0”，表明第一小区不支持URLLC业务。而对于V2X业务或有配置有专用资源的业务，除了这种显式的指示方式之外，还可以有隐式的指示方式。例如，依然可以通过指示信息所包括的一个或多个比特来指示一个小区或一个频率是否支持V2X业务，例如例如通过一个指示信息中的一个比特来指示第一信息是否支持V2X业务，指示方式可以是，如果这1比特的取值为“1”，表明第一信息存在V2X资源的配置，也就是表明为第一信息配置有V2X资源，而如果这1比特的取值为“0”，表明第一信息不存在V2X资源的配置，也就是表明第一信息未被配置V2X资源。如果指示信息指示第一信息存在V2X资源的配置，也就可以认为是隐式指示了，第一信息支持V2X业务，而如果指示信息指示第一信息不存在V2X资源的配置，也就可以认为是隐式指示了，第一信息不支持V2X业务。通过这种隐式指示的方式，既可以指示第一信息是否配置了V2X资源，也可以指示第一信息是否支持V2X业务，能够便于终端设备获得更多的信息。至于网络设备在通过指示信息指示第一信息是否支持V2X业务时，究竟是采用显式指示方式还是隐式指示方式，可以由网络设备配置并通知终端设备，或者也可以通过协议规定，具体的不做限制。在前文均是以显式指示方式为例，如果需采用隐式指示方式，那么可直接将前文中用于指示第一信息是否支持V2X业务的描述直接替换为本段落所介绍的隐式指示方式即可，后文中也是类似的。
S32、网络设备发送所述第一消息，终端设备接收来自网络设备的所述第一消息。
例如网络设备在第一小区发送第一消息，终端设备在第一小区接收第一消息。其中，如果第一消息是系统消息，那么网络设备可以是广播第一消息。
S33、终端设备根据所述第一消息包括的K个指示信息，确定M个第一信息中的每个第一信息是否支持相应的业务，其中，所述K个指示信息中的每个指示信息对应一种或多种业务，所述每个指示信息用于指示所述M个第一信息中的一个第一信息是否支持所述一种或多种业务，所述第一信息为小区信息或频率信息，M为正整数，K为大于或等于M的整数。
终端设备接收第一消息后，可以根据K个指示信息确定M个第一信息中的每个第一信息是否支持 相应的业务，具体的确定方式与前文中所述的指示信息具体的指示方式有关，简单来讲，指示信息指示的内容，也就是终端设备可以确定的内容。因此可参考前文中的相关介绍。
作为一种可选的方式，可以考虑只将本申请实施例提供的技术方案用于新版本的终端设备，因为对于老版本的终端设备来说可能无法识别本申请实施例所提供的指示信息，因此可能无法根据本申请实施例的方案确定相应的小区或频率是否支持相应的业务。那么对于老版本的终端设备来说，如果移动到5G网络和4G网络的重复覆盖区域，也就是SA布网方式和NSA布网方式的重复覆盖区域，则该终端设备会优先接入按照SA布网方式部署的5G网络中。而运营商在按照SA布网方式部署5G网络时，可能5G网络下的一些网络设备只能提供特定业务，例如只提供URLLC业务，而如果该网络设备按照现有技术中的方式拒绝终端设备驻留，则会拒绝所有的终端设备驻留，但是该网络设备又需要向一些终端设备提供服务，因此不能选择拒绝终端设备驻留。如果驻留的终端设备需要的是其他业务，例如需要eMBB业务，则该网络设备无法提供，导致该终端设备无法正常工作。为此，网络设备还可以在第一小区发送系统消息，例如为SIB1，该SIB1中的cellreservedforotheruse字段可以用于指示拒绝终端设备驻留。
终端设备接收来自网络设备的SIB1后，如果该终端设备是老版本的终端设备，则可以根据cellreservedforotheruse字段确定第一小区是拒绝驻留的，从而该终端设备可以不驻留在第一小区，而是重新选择驻留到其他小区。在这种情况下，无论第一小区是否能够提供老版本的终端设备所需要的业务，都会拒绝老版本的终端设备驻留，而即使第一小区能够提供老版本的终端设备所需要的业务，第一小区拒绝驻留，终端设备可以继续选择其他的小区，照样可以在其他小区正常工作，而本申请实施例这样处理，可以尽量减少终端设备驻留在不能提供所需的业务的小区的概率。
或者，终端设备接收来自网络设备的SIB1后，如果该终端设备是新版本的终端设备，则该终端设备不会根据cellreservedforotheruse字段确定是否驻留在第一小区，也就是说对于新版本的终端设备来说，不会考虑cellreservedforotheruse字段，而是会根据本申请实施例提供的K个第一信息确定第一小区是否支持该终端设备所需的业务，从而确定是否驻留在第一小区。
作为一种可选的实施方式，网络设备除了可以发送第一消息之外，还可以发送第二消息，第二消息可以包括对应于M个第一信息的时间信息。例如，第一消息和第二消息可以是同一条消息，或者也可以是不同的消息。如果第一消息和第二消息是不同的消息，那么网络设备可以先发送第一消息再发送第二消息，或者可以先发送第二消息再发送第一消息，或者可以同时发送第一消息和第二消息。
例如，第二消息包括的时间信息可以与指示信息一一对应，也就是说，第二消息可以包括K个时间信息，K个时间信息中的每个时间信息用于指示对应的一个指示信息所对应的第一信息在一个时间段内支持与该指示信息对应的一种或多种业务，或者，K个时间信息中的每个时间信息用于指示对应的一个指示信息所对应的第一信息在一个时间段内不支持与该指示信息对应的一种或多种业务。例如，K个时间信息中的一个时间信息为第一时间信息，第一时间信息是一个时间段的信息，第一时间信息与K个指示信息中的第一指示信息对应，第一指示信息用于指示第一小区是否支持URLLC业务和V2X业务。那么第一时间信息就用于指示，第一小区在第一时间信息所对应的时间段内支持URLLC业务和V2X业务，或指示第一小区在第一时间信息所对应的时间段内不支持URLLC业务和V2X业务。
或者，第二消息包括的时间信息中的每个时间信息可以对应一种业务，由于K个指示信息用于指示M个第一信息中的每个第一信息是否支持相应的业务，因此业务和第一信息以及指示信息都是对应的。一种业务对应一个第一信息，一种业务对应一个指示信息(一个指示信息可以指示一种或多种业务)，则一个时间信息可以用于指示对应的第一信息在一个时间段内支持该时间信息对应的业务，或者用于指 示对应的第一信息在一个时间段内不支持该时间信息对应的业务。例如，K个时间信息中的一个时间信息为第一时间信息，第一时间信息是一个时间段的信息，第一时间信息与URLLC业务对应，K个指示信息中的第一指示信息用于指示第一小区是否支持URLLC业务和V2X业务。那么第一时间信息就用于指示，第一小区在第一时间信息所对应的时间段内支持URLLC业务，或指示第一小区在第一时间信息所对应的时间段内不支持URLLC业务。
对于一个小区或频率来说，在有些情况下，可能是一段时间内支持某种业务，而在另一段时间内不支持该业务，例如一个小区本来支持URLLC业务和eMBB业务，而在一段时间内可能该小区对于URLLC业务的要求较高，那么在这段时间该小区可能会停止支持eMBB业务，而只支持URLLC业务，但在这段时间过后，该小区又可以恢复支持eMBB业务。因此本申请实施例考虑到小区或频率的这一特性，为相应的指示信息或业务添加时间信息，从而为一个小区或一个频率支持或不支持相应的业务添加一个时限，在该时限内该小区或频率支持相应的业务，在该时限外该小区或频率不支持相应的业务，或者在该时限内该小区或频率不支持相应的业务，在该时限外该小区或频率支持相应的业务，使得对于小区是否支持某些业务的指示更符合实际情况。
如果终端设备根据K个指示信息确定第一小区支持该终端设备所需的业务(或者，确定第一小区在一个时间段内支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第一小区在一个时间段内不支持该终端设备所需的业务，当前时刻不属于该时间段)，且终端设备当前已驻留在第一小区，则终端设备可以继续驻留在第一小区。
或者，如果终端设备根据K个指示信息确定第一小区不支持该终端设备所需的第一业务(或者，确定第一小区在一个时间段内不支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第一小区在一个时间段内支持该终端设备所需的业务，当前时刻不属于该时间段)，且终端设备当前已接入第一小区，则终端设备可以通过小区重选或小区切换等方式，重新选择驻留到其他小区，以能够正常进行第一业务。
或者，如果终端设备根据K个指示信息确定第一小区支持该终端设备所需的部分业务(或者，确定第一小区在一个时间段内支持该终端设备所需的部分业务，当前时刻已属于该时间段，或者，确定第一小区在一个时间段内不支持该终端设备所需的部分业务，当前时刻不属于该时间段)，且该终端设备当前已驻留在第一小区，则终端设备可以继续驻留在第一小区，并可以在第一小区发起第一小区所支持的业务。后续，当该终端设备需要发起第一小区所不支持的业务时，可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持第一小区所不支持的业务的小区；或者，当该终端设备需要发起第一小区所不支持的业务业务时，该终端设备可以再次判断第一小区是否支持该业务(例如网络设备可能会周期性发送第一消息，那么终端设备可以多次接收第一消息，从而终端设备可以根据新接收的第一消息包括的K个指示信息判断第一小区是否支持该业务)，如果确定第一小区改变为能够支持该业务，则可以继续驻留在第一小区，而如果确定第一小区还是不支持该业务，该终端设备可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持该业务的小区。
例如，终端设备所需的业务包括URLLC业务和eMBB业务，该终端设备根据K个指示信息确定第一小区支持eMBB业务，而不支持URLLC业务，且该终端设备当前已驻留在第一小区，则终端设备可以继续驻留在第一小区，并可以在第一小区发起eMBB业务。后续，当该终端设备需要发起URLLC业务时，可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持URLLC业务的小区；或者，当该终端设备需要发起URLLC业务时，该终端设备可以再次判断第一小区是否支持URLLC业务(例如网络设备可能会周期性发送第一消息，那么终端设备可以多次接收第一消息，从而终端设备可 以根据新接收的第一消息包括的K个指示信息判断第一小区是否支持URLLC业务)，如果确定第一小区支持URLLC业务，则可以继续驻留在第一小区，而如果确定第一小区还是不支持URLLC业务，该终端设备可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持URLLC业务的小区。
或者，如果终端设备根据K个指示信息确定第一小区不支持该终端设备所需的第一业务(或者，确定第一小区在一个时间段内不支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第一小区在一个时间段内支持该终端设备所需的业务，当前时刻不属于该时间段)，且终端设备当前已驻留在第一小区，该终端设备还是可以继续驻留在第一小区，例如，该终端设备当前可能暂时不需要进行第一业务，则可以继续驻留在第一小区。后续，当该终端设备需要发起第一业务时，可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持第一业务的小区；或者，当该终端设备需要发起第一业务时，该终端设备可以再次判断第一小区是否支持第一业务(例如网络设备可能会周期性发送第一消息，那么终端设备可以多次接收第一消息，从而终端设备可以根据新接收的第一消息包括的K个指示信息判断第一小区是否支持第一业务)，如果确定第一小区支持第一业务，则可以继续驻留在第一小区，而如果确定第一小区还是不支持第一业务，该终端设备可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持第一业务的小区。
或者，终端设备在进行小区切换时，可以根据K个指示信息确定第二小区是否支持该终端设备所需的第一业务，如果确定第二小区支持第一业务(或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻不属于该时间段)，终端设备可以切换到第二小区；而如果确定第二小区不支持第一业务(或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻不属于该时间段)，终端设备可以不切换到第二小区，或者终端设备可以将第二小区的优先级设置为低优先级。第二小区的优先级用于在进行小区重选或切换时终端设备对第二小区的选择顺序，如果将第二小区设置为低优先级，则终端设备会优先选择高优先级的小区，选择第二小区的概率较小，从而尽量保证终端设备能够驻留到能够提供第一业务的小区。第二小区可以是指终端设备切换后的小区，或者称为目标小区。
或者，终端设备在进行小区重选时，可以根据K个指示信息确定第二小区是否支持该终端设备所需的第一业务，如果确定第二小区支持第一业务(或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻不属于该时间段)，终端设备可以重选到第二小区；而如果确定第二小区不支持第一业务(或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻不属于该时间段)，终端设备可以不重选到第二小区，或者终端设备可以将第二小区的优先级设置为低优先级。第二小区的优先级用于在进行小区重选或切换时终端设备对第二小区的选择顺序，如果将第二小区设置为低优先级，则终端设备在小区重选时会优先选择高优先级的小区，选择第二小区的概率较小，从而尽量保证终端设备能够驻留到能够提供第一业务的小区。此时，第二小区可以是指终端设备在进行小区重选后接入的小区。
或者，终端设备在进行小区重选或小区切换时，如果终端设备确定第二小区支持第一业务(或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻不属于该时间段)，则终端设备可以重选或切换到第二小区，并可以在第二小区发起第二小区所支持的业务。后续，当该终端设备需要发起第二小区所不支持的业务时，可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持第二 小区所不支持的业务的小区；或者，当该终端设备需要发起第二小区所不支持的业务时，该终端设备可以再次判断第二小区是否支持该业务(例如网络设备可能会周期性发送第一消息，那么终端设备可以多次接收第一消息，从而终端设备可以根据新接收的第一消息包括的K个指示信息判断第二小区是否支持该业务)，如果确定第一小区改变为能够支持该业务，则可以继续驻留在第二小区，而如果确定第二小区还是不支持该业务，该终端设备可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持该业务的小区。
例如，终端设备所需的业务包括URLLC业务和eMBB业务。该终端设备在进行小区重选或小区切换时，确定第二小区支持eMBB业务，而不支持URLLC业务，则终端设备可以重选或切换到第二小区，并可以在第二小区发起eMBB业务。后续，当该终端设备需要发起URLLC业务时，可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持URLLC业务的小区；或者，当该终端设备需要发起URLLC业务时，该终端设备可以再次判断第二小区是否支持URLLC业务(例如网络设备可能会周期性发送第一消息，那么终端设备可以多次接收第一消息，从而终端设备可以根据新接收的第一消息包括的K个指示信息判断第二小区是否支持URLLC业务)，如果确定第二小区支持URLLC业务，则可以继续驻留在第二小区，而如果确定第二小区还是不支持URLLC业务，该终端设备可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持URLLC业务的小区。
或者，终端设备在进行小区重选或小区切换时，如果确定第二小区不支持第一业务(或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻不属于该时间段)，该终端设备还是可以重选或切换到第二小区，例如，该终端设备当前可能暂时不需要进行第一业务，则可以重选或切换到第二小区。后续，当该终端设备需要发起第一业务时，可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持第一业务的小区；或者，当该终端设备需要发起第一业务时，该终端设备可以再次判断第二小区是否支持第一业务(网络设备可能会周期性发送第一消息，那么终端设备可以多次接收第一消息，从而终端设备可以根据新接收的第一消息包括的K个指示信息判断第二小区是否支持第一业务)，如果确定第二小区支持第一业务，则可以继续驻留在第二小区，而如果确定第二小区还是不支持第一业务，该终端设备可以直接发起小区重选或小区切换等过程，以切换或重选到其他能够支持第一业务的小区。
又或者，终端设备在进行小区重选或小区切换时，可以先不考虑第二小区是否支持该终端设备所需的业务，而是根据正常流程进行小区重选或小区切换。在重选或切换到第二小区后，如果终端设备需要进行相应的业务，例如终端设备需要进行第一业务，终端设备再来判断第二小区是否支持第一业务。如果终端设备确定第二小区支持第一业务(或者，确定第二小区在一个时间段内支持该终端设备所需的业务，当前时刻已属于该时间段，或者，确定第二小区在一个时间段内不支持该终端设备所需的业务，当前时刻不属于该时间段)，则终端设备可以继续驻留在第二小区，并可以在第二小区发起第一业务；或者，如果第二小区不支持第一业务，终端设备可以发起小区重选或小区切换等过程，以切换或重选到其他能够支持第一业务的小区。
也就是说，终端设备可以在进行小区切换或小区重选时就判断第二小区是否支持该终端设备所需的业务，从而可以一开始就尽量避免接入不支持该终端设备所需的业务的小区，减少终端设备的重选或切换次数。或者，终端设备也可以在需要进行相应的业务时再判断所驻留的小区是否支持该终端设备所需的业务，因为即使是不支持终端设备所需的业务的小区，也可能能够为终端设备提供其他的服务，终端设备依然可以在该小区完成相应的工作，这也可以降低终端设备在进行小区切换或小区重选时的复杂度。
第一业务可以包括URLLC业务、eMBB业务、mMTC业务或V2X业务中的至少一种，或者也可 以不包括这四种业务，而是包括除了这四种业务之外的其他的业务，或者既包括这四种业务中的至少一种，也包括除了这四种业务之外的其他的业务。例如，第一业务可以是URLLC业务、或eMBB业务、或mMTC业务、或V2X业务，或者还可以是除了这四种业务之外的其他业务；或者，第一业务可以是URLLC业务和eMBB业务，或者是URLLC业务和mMTC业务，或者是eMBB业务和mMTC业务，或者是URLLC业务、eMBB业务和mMTC业务，或者是URLLC业务和V2X业务，或者是eMBB业务和V2X业务，或者是mMTC业务和V2X业务，或者是URLLC业务、eMBB业务和V2X业务，或者是URLLC业务、mMTC业务和V2X业务，或者是mMTC业务、eMBB业务和V2X业务，或者是URLLC业务、eMBB业务、V2X业务和mMTC业务，或者可以不包括这四种业务，而是包括除了这四种业务之外的其他的业务，或者可以包括这四种业务中的至少一种，以及包括除了这四种业务之外的其他业务，例如包括URLLC业务和V2X业务，以及包括除了这四种业务之外的其他业务。
在本申请实施例中，第一消息可以包括K个指示信息，每个指示信息可以指示一个小区或一个频率是否支持一种或多种业务，终端设备在接收第一消息后就可以确定相应的小区或频率是否支持相应的业务，从而终端设备可以选择不驻留到这些小区或频率，或者如果终端设备已经处在该小区或频率下，终端设备也可以通过小区重选等方式接入其他的小区或频率。通过这种方式，使得终端设备可以选择接入能够提供终端设备所需的业务的小区或频率，从而终端设备可以正常工作。对于网络设备来说，所提供的业务能够被终端设备所应用，也提高了资源的利用率。
为了解决同样的技术问题，本申请实施例提供第二种消息发送、接收方法，请参见图4，为该方法的流程图。在下文的介绍过程中，以该方法应用于图2所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第三通信装置和第四通信装置，其中，第三通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第三通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。对于第四通信装置也是同样，第四通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第四通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。且对于第三通信装置和第四通信装置的实现方式均不做限制，例如第三通信装置可以是网络设备，第四通信装置是终端设备，或者第三通信装置和第四通信装置都是网络设备，或者第三通信装置和第四通信装置都是终端设备，或者第三通信装置是网络设备，第四通信装置是能够支持终端设备实现该方法所需的功能的通信装置，等等。其中，网络设备例如为基站。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第三通信装置是网络设备、第四通信装置是终端设备为例。如果将本实施例应用在图2所示的网络架构，下文中所述的用于执行图3所示的实施例的网络设备可以是图2所示的网络架构中的网络设备，下文中所述的终端设备可以是图2所示的网络架构中的终端设备。
S41、网络设备生成第一消息，所述第一消息包括K个第一信息，所述第一消息用于指示所述K个第一信息支持第一业务或不支持第一业务，所述第一信息为小区信息或频率信息，K为正整数。
第一业务可以包括URLLC业务、eMBB业务、mMTC业务或V2X业务中的至少一种，或者也可以不包括这四种业务，而是包括除了这四种业务之外的其他的业务，或者既包括这四种业务中的至少一种，也包括除了这四种业务之外的其他的业务。例如，第一业务可以是URLLC业务、或eMBB业务、或mMTC业务、或V2X业务，或者还可以是除了这四种业务之外的其他业务；或者，第一业务可以是URLLC业务和eMBB业务，或者是URLLC业务和mMTC业务，或者是eMBB业务和mMTC业务，或者是URLLC业务、eMBB业务和mMTC业务，或者是URLLC业务和V2X业务，或者是eMBB业 务和V2X业务，或者是mMTC业务和V2X业务，或者是URLLC业务、eMBB业务和V2X业务，或者是URLLC业务、mMTC业务和V2X业务，或者是mMTC业务、eMBB业务和V2X业务，或者是URLLC业务、eMBB业务、V2X业务和mMTC业务，或者可以不包括这四种业务，而是包括除了这四种业务之外的其他的业务，或者可以包括这四种业务中的至少一种，以及包括除了这四种业务之外的其他业务，例如包括URLLC业务和V2X业务，以及包括除了这四种业务之外的其他业务。
例如，第一消息包括一个列表，该列表里包括K个第一信息，K个第一信息例如为K个小区信息，例如K个小区的ID，或者K个第一信息例如为K个频率信息，只要位于该列表里的第一信息，就表明支持或不支持第一业务。至于第一消息包括的K个第一信息究竟表示支持第一业务还是不支持第一业务，可以由网络设备预先通知终端设备，或者可以通过协议规定。这种方式较为简单，只要将支持第一业务(或不支持第一业务)的第一信息添加到第一消息中发送即可，无需为相应的第一信息添加指示信息，使得第一消息的结构较为简单，也易于实现。
第一消息例如为系统消息，例如SIB或MIB，或者也可以是其他消息，例如可以是UE专用(UE specific)信令。例如，网络设备一般都会通过系统消息广播邻区信息或邻频信息，那么网络设备除了通过系统消息广播邻区信息之外，还可以广播第一消息，第一消息所包括的K个第一信息可以属于网络设备所包括的邻区信息，或者，网络设备除了通过系统消息广播邻频信息之外，还可以广播第一消息，第一消息所包括的K个第一信息可以属于网络设备所包括的邻频信息。或者，即使网络设备不广播邻区信息，也可以广播包括K个小区信息的第一消息，或者，即使网络设备不广播邻频信息，也可以广播包括K个频率信息的第一消息。
S42、网络设备发送所述第一消息，终端设备接收来自网络设备的所述第一消息。
例如，网络设备可以在第一小区发送第一消息，第一小区可以是该终端设备的服务小区，S41中所述的邻区信息也就是第一小区的邻区信息，S41中所述的邻频信息也就是第一小区的频率的邻频信息。
S43、终端设备根据所述第一消息包括所述K个第一信息，确定所述K个第一信息中的每个第一信息支持所述第一业务或不支持所述第一业务，所述第一信息为小区信息或频率信息，K为正整数。
终端设备接收第一消息后，如果第一消息用于指示K个第一信息支持第一业务，则终端设备可以确定K个第一信息中的每个第一信息支持第一业务；或者，如果第一消息用于指示K个第一信息不支持第一业务，终端设备可以确定K个第一信息中的每个第一信息不支持第一业务。
终端设备在进行小区切换时，可以根据第一消息确定第二小区是否支持第一业务，例如第二小区是K个第一信息中的一个第一信息对应的小区。如果确定第二小区支持第一业务，终端设备可以切换到第二小区；而如果确定第二小区不支持第一业务，终端设备可以不切换到第二小区，或者终端设备可以将第二小区的优先级设置为低优先级。第二小区的优先级用于在进行小区重选或切换时终端设备对第二小区的选择顺序，如果将第二小区设置为低优先级，则终端设备会优先选择高优先级的小区，选择第二小区的概率较小，从而尽量保证终端设备能够驻留到能够提供第一业务的小区。第二小区可以是指终端设备切换后的小区，或者称为目标小区。
或者，终端设备在进行小区重选时，可以根据第一消息确定第二小区是否支持该终端设备所需的第一业务，例如第二小区是K个第一信息中的一个第一信息对应的小区。如果确定第二小区支持第一业务，终端设备可以重选到第二小区；而如果确定第二小区不支持第一业务，终端设备可以不重选到第二小区，或者终端设备可以将第二小区的优先级设置为低优先级。第二小区的优先级用于在进行小区重选或切换时终端设备对第二小区的选择顺序，如果将第二小区设置为低优先级，则终端设备在小区重选时会优先选择高优先级的小区，选择第二小区的概率较小，从而尽量保证终端设备能够驻留到能够提供第 一业务的小区。此时，第二小区可以是指终端设备在进行小区重选后接入的小区。通过本申请实施例提供的技术方案，能够使得终端设备明确相应的邻频或邻频是否支持终端设备所需的业务，从而终端设备在进行小区切换或小区重选时能够尽量接入能够支持该终端设备所需的业务的小区，以在这样的小区正常工作。而且本申请实施例只需通过第一消息就可以指示多个第一信息是否支持第一业务，方式较为简单。

在一种可能的实施方式中，收发器502，还用于在所述第一小区发送第二消息，所述第二消息包括对应于所述M个第一信息的时间信息，其中，所述时间信息包括如下至少一种：
