Description

通信方法和通信装置
本申请要求于2022年2月15日提交中国专利局、申请号为202210137763.5、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种用于混合组网中进行小区搜索和驻留的通信方法和通信装置。
背景技术
在当前的通信协议中，对于每个频率(即频点)，仅要求终端尝试在该频率信号最强的小区上驻留。即现有的搜索网络方式是，终端对当前频率进行小区搜索过程，发现该频率上所有小区信号，对其中最强的一个小区信号尝试获取主系统信息块(master information block，MIB)和系统信息块(system information block，SIB)的信息，在获取MIB和SIB信息成功后，根据驻留准则进行驻留判断。如果获取MIB/SIB信息失败，或者最强小区的MIB/SIB信息不满足驻留条件，那么终端放弃该信号最强小区及所在频率，直接在搜索频段中下一个频率再次尝试进行驻留。但是在混合组网场景中，目标网络中信号最强的小区可能并不是某个频率下的信号最强小区，因此按照现有技术实现，会导致小区驻留过程中无法快速驻留到目标网络的小区上，大破之驻留速度过慢，甚至错过目标网络小区信号导致驻留失败。如果后续频率没有目标网络小区，那么终端丢覆盖表现为无法驻留到目标网络；即使，后面驻留到了目标网络小区，也错失了第一次可驻留的小区，表现为终端驻留速度慢。
也就是说，当前小区搜索的技术方案，在混合组网场景下存在小区搜索和驻留失败以及搜索速度较慢的问题。

在本申请技术方案中，主要增加了对第一小区是否是目标小区的判断，从而避免了当第一小区不是目标小区时，无效的驻留尝试导致的失败和时间过长，也就是说，能够有效 解决目标小区的能量低于非目标小区能量时导致的驻留失败、驻留时间过长等问题。

结合第一方面，在第一方面的某些实现方式中，在判断第二小区是否是目标小区时，可以通过执行下面的操作实现：获取第二小区的SIB1信息；根据第二小区的SIB1信息，判断第二小区是否属于目标网络，当第二小区属于目标网络时，第二小区是目标小区，当第二小区不属于目标网络时，第二小区不是目标小区。
结合第一方面，在第一方面的某些实现方式中，在判断第三小区是否是目标小区时，可以通过执行下面的操作实现：获取第三小区的SIB1信息；根据第三小区的SIB1信息，判断第三小区是否属于目标网络，当第三小区属于目标网络时，第三小区是目标小区，当第三小区不属于目标网络时，第三小区不是目标小区。
结合第一方面，在第一方面的某些实现方式中，混合组网可以为以下任意一种混合方式：公共陆地移动网络和非公共网络的混合、独立组网和非独立组网的混合，或者多个运营商网络的混合。

本申请的通信系统可以遵从第三代合作伙伴计划(third generation partnership project，3GPP)的无线通信标准，也可以遵从其他无线通信标准，例如电气电子工程师学会(Institute of Electrical and Electronics Engineers，IEEE)的802系列(如802.11，802.15，或者802.20)的无线通信标准。
在本申请实施例中，主要针对混合组网场景中的主流小区的问题展开。混合组网可以理解为是多种不同类型的网络混合在一起，例如，可以是公共陆地移动网络(public land mobile network，PLMN)和非公共网络(non-public network，NPN)的混合，可以是独立组网(standalone，SA)网络和非独立组网(non-standalone，NSA)的混合，可以是签约运营商网络和非签约运营商网络的混合，还可以是上述任意多种网络的混合，即上述网络中的至少两种网络的混合。运营商网络可以包括移动、电信、联通等运营商的网络。

其中，可穿戴设备也可以称为穿戴式智能设备，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、智能首饰等。此外，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。本申请实施例对终端设备所采用的具体技术和具体设备形态不做限定。
本申请实施例中，网络设备可以是任意一种具有无线收发功能的设备。网络设备包括但不限于：宏基站、微基站(也称为小站)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，WiFi系统中的AP、WiMAX中的(base station，BS)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G(如，NR)系统中的下一代基站节点(next generation node base station，gNB)或传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如分布式单元(distributed unit，DU)，或者下一代通信6G系统中的基站等。本申请实施例对网络设备所采用的具体技术和具体设备形态不做限定。

为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例的通信系统。图1是适用于本申请实施例的通信系统的一种架构的示意图。如图1所示，该通信系统100可以包括至少一个网络设备，例如图1所示的网络设备110；该通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备120。网络设备110与终端设备120可通过无线链路通信。
应理解，该无线通信系统中的网络设备110可以是上文所述任意一种具有无线收发功能的设备。例如可以是基站。该终端设备120也可以是上文所述任意一种终端设备。
如图1所示，该无线通信系统中，网络设备110可通过集成或外接的天线设备，为特定地理区域提供通信覆盖。位于网络设备110的通信覆盖范围内的一个或多个终端设备120，均可以接入网络设备110。一个网络设备110可以管理一个或多个小区(cell)。每个小区具有一个身份证明(identification，ID)，该身份证明也被称为小区标识(cell identity，cell ID)。从无线资源的角度看，一个小区是下行无线资源，以及与其配对的上行无线资 源(非必需)的组合。
终端设备120和网络设备110应知晓该无线通信系统预定义的配置，包括系统支持的无线电接入技术(radio access technology，RAT)以及系统规定的无线资源配置等，比如无线电的频段和载波的基本配置。载波是符合系统规定的一段频率范围。这段频率范围可由载波的中心频率(记为载频)和载波的带宽共同确定。这些系统预定义的配置可作为无线通信系统的标准协议的一部分,或者通过终端设备120和网络设备110间的交互确定。相关标准协议的内容，可能会预先存储在终端设备120和网络设备110的存储器中，或者体现为终端设备120和网络设备110的硬件电路或软件代码。
该无线通信系统中，终端设备120和网络设备110支持一种或多种相同的RAT，例如5G NR，4G LTE，或未来演进系统的RAT。具体地，终端设备120和网络设备110采用相同的空口参数、编码方案和调制方案等，并基于系统规定的无线资源相互通信。
为了便于理解本申请实施例的方案，下面结合图1所示场景，举例说明。假设当前的混合组网中包括小区A和小区B，其中小区A和小区B是不同的网络，例如，小区A是PLMN网络，小区B是NPN网络，且小区B是终端设备120希望接入的目标网络。终端设备120通过网络搜索，搜索到小区A和小区B，且小区A的信号最强，小区B的信号次强(即是除小区A以外的信号最强的小区)。根据现有技术，则终端设备120会尝试在小区A驻留，而由于小区A不是终端设备120希望接入的目标网络，导致不满足小区A的驻留条件，驻留失败。
针对上述问题，在本申请实施例中，则是终端设备120在搜索到小区A和小区B后，判断小区A是否是目标小区，如果是则直接驻留，如果不是则再次搜索小区信号。当再次搜索时，由终端设备就会尝试在小区B驻留，此时终端设备120满足小区B的驻留条件，从而可以驻留成功。
图2是本申请实施例提供的一种通信方法的示意性流程图。下面对图2的各个步骤进行介绍。
201、终端设备在当前频率上执行小区搜索，得到第一小区。
需要说明的是“当前频率”可以理解为终端设备开始搜索小区信号时正处在的频点/频次/频率，也可以称之为“当前频次”、“当前频点”。与之对应，“下一频率”则可以理解为“当前频率”之后的一个频点/频次/频率。
上述第一小区为混合组网中信号最强的小区。也就是说，第一小区是在搜索到的所有小区中信号最强(能量最强)的小区。
可选地，混合组网可以为以下任意一种混合方式：公共陆地移动网络和非公共网络的混合、独立组网和非独立组网的混合，或者多个运营商网络的混合。运营商网络例如可以包括以下常见的运营商：移动、联通或电信等。
202、终端设备判断第一小区是否为混合组网中的目标小区。
在一些实现方式中，当第一小区不是目标小区时，可以将第一小区添加到禁止小区列表；则在再次执行小区搜索的时候就可以过滤掉第一小区。需要说明的是，当第一小区是目标小区时，可以直接驻留到第一小区。
目标小区用于表示目标网络的小区，即为终端设备期望接入的网络中的小区。例如，假设终端设备的签约运营商网络为电信网络，目标小区就可以是期望接入的电信网络中的 小区，或者理解为是电信网络覆盖的小区，在此不再一一列举。
在本申请实施例中，会判断信号最强的第一小区是不是目标小区，如果不是则会在此进行小区搜索。在现有技术中，不会判断第一小区是否是目标小区，也不会再次进行小区搜索，因为现有技术会直接选择信号最强的小区进行驻留。
可选地，在判断第一小区是否是混合组网中的目标小区时，可以通过执行下面的操作来实现：获取第一小区的SIB1信息；以及根据第一小区的SIB1信息，判断第一小区是否属于目标网络，当第一小区属于目标网络时第一小区是目标小区，当第一小区不属于目标网络时第一小区不是目标小区。
203、当第一小区不是目标小区时，终端设备继续在当前频率上执行小区搜索，得到第二小区。
第二小区是上述混合组网中除第一小区之外信号最强的小区。也就是说，第二小区是在搜索到的所有小区中信号次强(能量次强)的小区。
可选地，可以进一步判断第二小区是否是目标小区，当第二小区是目标小区时，在在第二小区驻留。
如上所述，在一些实现方式中，当发现第一小区不是目标小区时，可以对第一小区进行屏蔽，则在执行步骤203时，即再次搜索小区信号时，可以剔除掉(过滤掉)第一小区。
在再次搜索到的小区中，可以从除第一小区之外的其他小区中确定要驻留的小区。这样能够有效避免第一小区不是目标小区时，终端设备尝试驻留第一小区导致的失败和时间过长。
可选地，当在当前频率上再次搜索小区信号时，过滤掉禁止小区列表中的小区。
204、终端设备判断第二小区是否为目标小区，以及当第二小区是目标小区时在第二小区驻留。
第二小区是所有小区中除第一小区之外的信号最强的小区，也可以理解为，第二小区是信号仅次于第一小区的小区，或者第二小区是信号次强的小区。
可选地，在判断第二小区是否是混合组网中的目标小区时，可以通过执行下面的操作来实现：获取第二小区的SIB1信息；以及根据第二小区的SIB1信息，判断第二小区是否属于目标网络，当第二小区属于目标网络时第二小区是目标小区，当第二小区不属于目标网络时第二小区不是目标小区。
在步骤204中，当第二小区是目标小区时，驻留到第二小区。当第二小区不是所述目标小区时，可以执行下面两种实现方式的操作。
在第一种实现方式中，当第二小区不是所述目标小区时，可以在下一频率上执行小区搜索。这样可以避免终端设备尝试接入网络的时长过长。也就是说，在同一频率下只进行两次小区搜索，当信号最强的小区(第一小区)和信号次强的小区(第二小区)都不是目标小区的时候，在下一频率上再执行小区搜索。
在第二种实现方式中，当第二小区不是所述目标小区时，可以继续在当前频率上执行小区搜索，得到第三小区，所述第三小区是所述混合组网中除第一小区和第二小区之外信号最强的小区；以及判断第三小区是否是目标小区，当第三小区是目标小区时，在第三小区驻留。也就是说，第三小区是在搜索到的所有小区中信号第三强(能量第三强)的小区。在该实现方式中，在同一频率下进行了三次小区搜索，当信号最强的小区(第一小区)和 信号次强的小区(第二小区)不是目标小区且信号次次强的小区(第三小区)是目标小区的时候，在第三小区驻留。
在第三种实现方式中，当第二小区不是所述目标小区时，如第二种实现方式中的操作，继续在当前频率上执行小区搜索，得到上述第三小区，以及判断第三小区是否是目标小区。与第二种实现方式不同的是，在第三种实现方式中，第三小区不是目标小区，当第三小区不是目标小区时，类似于上述第一小区和第二小区，同样可以有两种操作：操作一是继续在当前频率上执行小区搜索和判断搜索到的小区是否为目标小区；操作二是在下一频率上再进行小区搜索。
简而言之，在第一种实现方式中，终端设备在同一频率下只执行了2次小区搜索和目标小区的判断，可以有效避免在同一频率下小区搜索和驻留花费的时间过长。在第二种实现方式中，终端设备在同一频率下执行了3次小区搜索和目标小区的判断。在第三种实现方式中，终端设备在同一频率下执行至少3次小区搜索和目标小区的判断，具体而言，当执行上述操作一时共执行了4次及以上的小区搜索和目标小区的判断，当执行时上述操作二时共执行了3次小区搜索和目标小区的判断。本实施例对具体的次数不做限制。但应理解，执行太多次数的小区搜索和目标小区的判断会一定程度上延长在同一频率下小区搜索和驻留花费的时间。
可选地，在判断第三小区是否是混合组网中的目标小区时，可以通过执行下面的操作来实现：获取第三小区的SIB1信息；以及根据第三小区的SIB1信息，判断第三小区是否属于目标网络，当第三小区属于目标网络时第三小区是目标小区，当第三小区不属于目标网络时第三小区不是目标小区。
在图2所示方法中，主要增加了对第一小区是否是目标小区的判断，从而避免了当第一小区不是目标小区时，无效的驻留尝试导致的失败和时间过长。
图3是图2所示通信方法的一个例子的示意性流程图。应理解图3是图2所示方法的一个具体示例，图3主要是针对PLMN网络和NPN网络组成的混合组网的场景。且在图3所示例子中，是以NPN网络中的小区为目标小区为例进行介绍的。
301、终端设备扫描频率1上的网络设备的小区信号，得到小区A和小区B，且小区A的信号最强。
小区A可以看作是第一小区的一个示例，小区B可以看作是第二小区的一个示例。
302、终端设备读取小区A的SIB1信息。
步骤301和302是步骤201的一个示例。
303、终端设备判断小区A是否为NPN网络的小区，当判断结果为否时，执行步骤304。
步骤303可以看作是步骤202的一个示例。
在一些实现方式中，还可以包括步骤310，当判断结果为是时，执行“终端设备驻留到小区A”。
304、终端设备将小区A添加到禁止小区列表。
305、终端设备在频率1上再次扫描网络设备的小区信号，得到小区A和小区B，且小区A的信号最强。
306、终端设备根据禁止小区列表，过滤掉小区A。
步骤304-306可以看作是步骤203的一个示例。
307、终端设备读取小区B的SIB1信息。
308、终端设备判断小区B是否为NPN网络的小区，当判断结果为是时，执行步骤309；当判断结果为否时，执行步骤311。
309、终端设备驻留到小区B。
311、在终端设备在频率2上执行小区搜索。
频率2可以为频率1的下一频率。
步骤307-309、311可以看作是步骤204的一个示例。
应理解图3只是一个示例，在实际应用中还存在其他实现方式，例如步骤311还可以是在频率1上再次进行小区搜索，得到小区C。但为了简洁，在此不再一一列举。
图4是图2所示通信方法的另一个例子的示意性流程图。应理解图4是图2所示方法的一个具体示例，图4主要是针对NSA网络和SA网络组成的混合组网的场景。且在图4所示例子中，是以SA网络中的小区为目标小区为例进行介绍的。
401、终端设备扫描频率1上的网络设备的小区信号，得到小区A和小区B，且小区A的信号最强。
小区A可以看作是第一小区的一个示例，小区B可以看作是第二小区的一个示例。
402、终端设备读取小区A的SIB1信息。
