Description

一种通信方法、装置及*** 技术领域
本申请实施例涉及通信领域，更具体地，涉及一种通信方法、装置及***。
背景技术
现有技术中，终端设备通过小区选择或者小区重选，驻留到合适的小区。在选择驻留小区的过程中，终端设备接收网络设备发送的小区选择参数，判断测量的小区信号强度和信号质量满足小区选择参数指示的门限值时，终端设备选择当前的小区进行驻留。
然而，终端设备支持的业务速率越高或终端设备的业务所需求的速率越高，终端设备所需的信号强度和信号质量越高，在进行小区选择或重选时，越需要选择通信质量好的小区进行驻留。在不同的应用场景中，业务速率需求不同。特别是在机器到机器(machine to machine，M2M)网络中，典型的应用场景很多，业务速率需求也很多样化，例如工业无线传感网络场景典型的业务速率可以低于2Mbps，视频监控场景典型的业务速率可以超过10Mbps。现有技术中网络设备发送的小区选择参数，会导致支持高速率业务的终端设备选择驻留小区后，网络设备无法满足其高速率业务的需求，或者，会导致网络设备可以满足其需求的支持低速率业务的终端设备无法驻留小区。现有技术中的问题严重影响了通信质量。
发明内容
本申请提供一种通信方法、装置及***，能够解决现有技术中小区选择参数与终端所支持的业务速率需求无法匹配的问题，提高通信质量。
第一方面，提供了一种通信方法，该方法由网络设备执行，或者也可以由配置于网络设备的部件(如电路或芯片)或网络设备的一个或单个模块执行。本申请对此不作限定。该方法包括：网络设备确定小区选择参数的一组或多组值，其中，所述小区选择参数的一组或多组值与一个或多个业务信息存在关联关系；所述网络设备发送所述小区选择参数的一组或多组值。
基于上述技术方案，网络设备可以针对不同的业务速率或业务信息配置不同的小区选择参数，使得终端设备在选择驻留的小区时可以根据自身所支持的业务或自身业务需求选择合适的小区进行驻留。例如，针对高速率业务，网络设备配置的小区选择参数对应更高的信号质量要求，保证了驻留小区后高速率业务的通信质量，避免驻留小区后该高速率业务的业务服务质量无法满足；另一方面，针对低速率业务，网络设备配置的小区选择参数对应较低的信号质量要求，距离小区更远的终端设备也可以驻留到小区，扩大了网络设备的覆盖范围。因此，上述技术方案解决了现有技术中小区选择参数与终端所支持的业务速率需求无法匹配的问题，从而保证了通信质量，改善了业务的服务质量，也可以扩大网络设备的覆盖范围。
在一种可能的设计中，所述关联关系是预定义的，或者，所述关联关系是所述网络设备发送的。
在所述关联关系是预定义的情况下，可以节省配置该关联关系所占用的信令资源。若所述关联关系是所述网络设备发送的，可以增加关联关系配置的灵活性，所述网络设备可以根据需要调整该关联关系。
在一种可能的设计中，所述小区选择参数的一组或多组值与所述一个或多个业务信息一一对应。

基于上述技术方案，终端设备可以接收网络设备针对不同业务速率或业务信息配置的不同小区选择参数，使得终端设备在选择驻留的小区时可以根据自身所支持的业务或自身业务需求选择合适的小区进行驻留。例如，高速率业务的终端设备根据自身业务确定小区选择参数，该小区选择参数对应更高的信号质量要求。因此，该终端设备不会驻留在通信质量较差的小区，保证了驻留小区后高速率业务的通信质量，避免驻留小区后该高速率业务的业务服务质量无法满足。另一方面，低速率业务的终端设备根据自身业务确定小区选择参数，该小区选择参数对应较低的信号质量要求，因此，该终端设备可以采用更低的门限驻留小区，因此距离小区更远的终端设备也可以驻留到小区，扩大了网络设备的覆盖范围。因此，上述技术方案解决了现有技术中小区选择参数与终端所支持的业务速率需求无法匹配的问题，从而保证了通信质量，改善了业务的服务质量，也可以扩大网络设备的覆盖范围。

UE通过小区选择或者小区重选过程，选择合适的小区进行驻留。在选择驻留小区的过程中，UE接收网络设备发送的小区选择参数，获知小区的信息，从而保证UE驻留小区后可以正常工作，传输速率可以达到UE所支持的业务的速率需求。UE通过对当前小区的信号进行测量，判断测量的小区信号强度和信号质量满足网络设备发送的小区选择参数指示的门限值时，选择当前的小区进行驻留。具体的，目前NR定义的小区选择准则为：
Srxlev>0 AND Squal>0
其中：
Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation-Qoffsettemp
Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)-Qoffsettemp
其中的参数如表1所示。
表1
网络通过小区选择参数指示RSRP门限和RSRQ门限，并通过空口发送该小区选择参数。终端设备接收当前小区的小区选择参数，根据小区选择参数确定当前小区的RSRP门限和RSRQ门限。终端设备对当前小区的信号进行测量，并获得测量的RSRP和测量的RSRQ。当测量的RSRP和测量的RSRQ与根据小区选择参数确定的RSRP门限和RSRQ门限满足上述公式时，终端选择驻留在当前的小区。
上述测量的RSRP和测量的RSRQ反映了终端设备在当前小区进行通信的通信质量，具体来说，反映了当前小区的信号强度和信号质量。通常，业务速率越高，该业务所需的信号强度和信号质量越高。因此，支持的业务速率较高的终端，或待完成较高速率业务的终端，或业务需求的速率较高的终端，在进行小区选择或重选时，需要选择信号强度较高和信号质量较好的小区进行驻留。若网络设备发送的小区选择参数的值较低，可能导致高速率业务所需的信号强度和信号质量高于网络配置的门限值，使得支持高速率业务的终端设备驻留当前小区后其业务的速率需求无法被满足。另一方面，若网 络设备发送的小区选择参数的值较高，也可能导致网络配置的门限值高于低速率业务所需的信号强度和信号质量，在这种情况下，网络有能力满足低速率业务的需求，但对于距离小区较远的支持低速率业务的终端，其测量的信号强度和/或质量无法满足小区的接入门限，导致这部分用户无法驻留当前小区，也就无法进行业务传输，相当于降低了所述小区的覆盖范围，另一方面，也会增加UE小区选择和重选的开销，降低用户体验。
在不同的应用场景中，业务速率需求不同。特别是在机器到机器(machine to machine，M2M)网络中，典型的应用场景很多，业务速率需求也很多样化，例如工业无线传感网络场景典型的业务速率通常小于或等于2Mbps，视频监控场景典型的业务速率可以超过10Mbps。当网络配置固定的小区选择参数值(例如RSRP门限和RSRQ门限)，存在小区选择参数与终端所支持的业务速率需求无法匹配的问题，导致高速率业务的服务质量下降，降低用户体验；还可能导致低速率业务的终端无法驻留小区，增加小区选择和重选的开销，降低用户体验，无法驻留也相当于降低了网络覆盖性能。
有鉴于此，本申请提供一种通信方法和装置，能够解决现有技术中小区选择参数与终端所支持的业务速率需求无法匹配的问题。网络设备确定并发送小区选择参数的一组或多组值，该小区选择参数与业务信息相关联。该方法可以使得终端根据所支持的业务速率或业务所需求的速率选择合适的小区选择参数进行小区选择或小区重选，能够解决现有技术中小区选择参数与终端所支持的业务速率需求无法匹配的问题，从而提高了通信质量，改善了业务的服务质量，提高用户体验，也可以解决网络覆盖性能下降的问题。
为了使本领域技术人员更好地理解本发明实施例提供的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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他实施例，都属于本发明保护的范围。
图2是本申请实施例提供的通信方法的一例示意图。该方法200可以包括S210至S230。该方法可以由终端设备和网络设备分别执行，或者也可以由终端设备中的芯片和网络设备中的芯片分别执行。应理解，图2示出了该通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形，或者是合理的步骤间的调换。
S210，网络设备确定小区选择参数的一组或多组值。其中，小区选择参数的一组或多组值与一个或多个业务信息存在关联关系。
应理解，在本申请实施例中，小区选择参数的一组或多组值可以用于小区选择，也可以用于小区重选。小区选择参数可以为小区选择/重选参数、小区接入参数等，关于其命名，本申请不予限制。
下面将分别介绍小区选择参数、业务信息以及关联关系。
1)小区选择参数
小区选择参数的一组或多组值，用于反映小区所需的信号强度或信号质量水平。
一种实施方式中，小区选择参数的一组值指示RSRP门限或RSRQ门限中的至少一个。可以理解，本申请实施例中的一组或多组是为了清楚表达的一种表述方式，不意味着分组的行为或结果，也不排斥分组的行为或结果。可以理解，本申请实施例中一组值的含义为一个或多个值，本申请实施例中的一组值可以仅包含一个值，本申请实施例中的一组值也可以包含多个值，这两种情况都属于本申请权利要求的保护范围。具体来说，小区选择参数的一组值可以是以下实现方式的一种：
仅包含RSRP门限；
仅包含RSRQ门限；
包含RSRP门限，对于其他的参数本申请不做限制；
包含RSRQ门限，对于其他的参数本申请不做限制；
仅包含RSRP门限和RSRQ门限；
包含RSRP门限和RSRQ门限，对于其他的参数本申请不做限制；
包含与小区所需的最小的信号强度或信号质量水平相关联的参数，例如，上述参数可以是表1中的参数，还可以是RSRP门限偏移值、RSRQ门限偏移值等，对于其他的参数本申请不做限制。
相应的，小区选择参数的多组值中的每一组值，都可以是上述列举的几种实现方式中的一种。可以理解，小区选择参数的多组值中不同的两组值，可以是上述列举的几种实现方式中不同的实现方式的组合，也可以是上述列举的几种实现方式中相同的实现方式。示例性的，上述小区选择参数的多组值中，第一组值仅包含RSRP门限，第二组值仅包含RSRP门限和RSRQ门限，第三组值仅包含RSRP门限。关于小区选择参数的一组或多组值，还可以参考本申请关于关联关系部分的示例。
可选的，小区选择参数可以直接指示RSRP门限的取值；或者小区选择参数可以指示与RSRP门限相关联的值，其中，小区选择参数指示的值与RSRP门限的关联可以满足预定义的规则；或者小区选择参数可以指示RSRP门限偏移值，其中，RSRP门限可以根据一个给定RSRP门限和小区选择参数指示的偏移值确定。下面将分别举例说明。可以理解，小区选择参数的指示方式可以是上述指示方式的任意组合。
方式一：小区选择参数可以直接指示RSRP门限的取值。例如，小区选择参数的取值为-80dBm或-80，则接收端，例如终端设备，根据网络设备配置的小区选择参数的取值可以确定RSRP门限为-80dBm。
方式二：小区选择参数可以指示与RSRP门限相关联的值。例如，小区选择参数的取值为-40dBm或-40，其中预定义的规则为：小区选择参数的取值的二倍为RSRP门限，则接收端，例如终端设备，根据小区选择参数的取值和预定义的规则可以确定RSRP门限为-80dBm。这样可以增加指示的数值范围，减少指示的开销。
方式三：小区选择参数可以指示RSRP门限偏移值。例如，小区选择参数的取值为-3dBm或-3，给定的RSRP门限为-80dBm，则接收端，例如终端设备，根据给定的RSRP门限和小区选择参数的取值可以确定RSRP门限为-83dBm。其中，给定的RSRP门限可以是通过方式一或方式二指示的，也可以是预定义的。方式三可以增加指示的数值范围，减少指示的开销。
RSRQ门限的指示方式可以参考上述RSRP门限的指示方式，本申请实施例在此不再赘述。可以理解，RSRP门限的指示方式和RSRQ门限的指示方式可以相同，也可以不同，二者的指示方式可以是上述指示方式的任意组合。
应理解，上述预定义的配置规则也可以是预配置的，以方式二为例，计算规则为小区选择参数的取值的2倍为RSRP门限，即步长2，那么网络设备可以在确定步长后，通过信令等方式预定义步长为0.5、1、1.5、2或3等多个候选参数中的一个，即值为步长2。这样可以灵活配置RSRP的取值范围，步长越小，指示的RSRP门限越精确，终端设备根据业务速率等信息确定出是否选择/重选的结果越准确，步长越大，对于指示信令开销更小，覆盖的RSRP门限取值范围越大。
2)业务信息
一种实施方式中，一个或多个业务信息，可以用于反映业务的服务质量信息(Quality of Service,QoS)。
一种实施方式中，业务信息包括业务速率信息，或者，业务信息包括业务类型。又一种实施方式中，业务信息包括其他可以反映业务的QoS的参数。
具体来说，业务信息可以是一个数值，也可以是一段数值范围，或者，可以是非数值的信息。以 业务速率为例，业务信息可以是2Mbps、10Mbps，业务信息也可以是2～6Mbps、6～10Mbps，业务信息也可以是预定义的业务速率高、业务速率低。具体配置的过程中，可以通过标识或数值或数值范围等方式指示业务信息。
具体来说，业务信息可以是按照会话/实时类、交互类、流媒体类业务划分的业务类型，也可以是按照语音、数据、视频等传输内容划分的业务类型，也可以进一步的按照视频通话、遥感勘测、网页浏览、电子邮件、静态图片传输、高质量多媒体视频等等更具体的业务划分业务类型。或者，业务信息也可以是按照业务速率范围划分的业务类型A、业务类型B等等，业务信息也可以是按照其他可以反映业务的QoS的参数划分的业务类型。以业务速率为例，可以将业务速率处于2～6Mbps的业务划分为业务类型1，将业务速率处于6～10Mbps的业务划分为业务类型2。再一个实施例中，业务类型可以根据应用(APP)标识确定。业务类型的划分方式很多，不限于本申请实施例中列举的划分方式，下文为了便于说明统一描述为业务类型1、业务类型2、业务类型3等等。
可选的，一个或多个业务信息是核心网(core network)确定的，或者，一个或多个业务信息是无线接入网(radio access network,RAN)确定的。
一种具体实施方式中，核心网根据全部或部分业务确定若干个业务类型；或者，核心网定义多个业务速率范围，并将上述信息发给RAN，RAN根据收到的一个或多个业务类型或业务速率范围，为每个业务类型或业务速率范围匹配相应的小区选择参数，确定出关联关系，并发送给终端设备。
又一种具体实施方式中，RAN根据全部或部分业务确定若干个业务类型，或者，RAN定义多个业务速率范围，并且为每个业务类型或业务速率范围匹配相应的小区选择参数，确定出关联关系，并发送给终端设备。
3)关联关系
一种实施方式中，小区选择参数的一组或多组值与一个或多个业务信息存在映射关系，进一步的，该映射关系可以是一一对应关系。可以理解，该映射关系也可以是多对一关系、一对多关系、多对多关系以及前述对应关系的组合。
下面将举例说明关联关系。可以理解，关联关系不限于以下示例中的实现方式，还可以包括其他可能的对应关系的组合。此外，关联关系也可以只包含下表中的部分行示出的关联关系。需要说明的是，业务速率范围的端值可以如表所示，也可以包含或不包含在对应的业务速率范围内。
示例一：多个业务速率范围与多组RSRP门限和RSRQ门限存在如表2所示的对应关系。在本示例中，业务速率范围为业务信息，RSRP门限和RSRQ门限为小区选择参数，关联关系为一一对应关系。在本申请的这些示例中，Data rate_2可以和Data rate_3相同，也可以不同，Data rate_4可以和Data rate_5可以相同，也可以不同，以此类推。在不同业务速率范围之间不交叠的情况下，终端设备可以根据业务速率范围确定出关联的RSRP门限和RSRQ门限。又一个实施例中，这些业务速率范围也可以存在交叠的情况。在这种情况下，终端设备可以在满足业务速率范围的多组小区选择参数中确定一个。这样可以增加终端设备的灵活性。
表2

应理解，这些示例还可以和前面介绍的指示方式相结合，业务信息的指示方式和小区选择参数的指示方式也可以任意组合。举例来说，示例一中的业务速率范围可以由网络直接指示，也可以通过指示数值范围的端值由网络间接指示；示例一中一组小区选择参数为一个RSRP门限和RSRQ门限，其中RSRP门限可以通过上述方式一至方式三中的一种或多种方式进行指示，RSRQ门限也可以通过上述方式一至方式三中的一种或多种方式进行指示，RSRP门限的指示方式和RSRQ门限的指示方式可以相同，也可以不同，二者的指示方式可以是上述指示方式的任意组合。
示例二：多个业务速率范围与一组RSRP门限和RSRQ门限存在如表3所示的对应关系。在本示例中，业务速率范围为业务信息，RSRP门限和RSRQ门限为小区选择参数，关联关系为多对一关系。对应关系还可以是一对多关系，即一个业务速率范围对应多组RSRP门限和RSRQ门限。

示例三：多个业务速率范围与多组RSRP门限和RSRQ门限存在如表4所示的对应关系。在本示例中，业务速率范围为业务信息，RSRP门限和RSRQ门限为小区选择参数，关联关系为多对一关系、一对多关系以及一对一关系的组合。

示例四：一个业务速率范围与一组RSRP门限和RSRQ门限存在如表5所示的对应关系。在本示例中，业务速率范围为业务信息，RSRP门限和RSRQ门限为小区选择参数，关联关系为一一对应关系。
表5
可以理解，小区选择参数的实现方式、业务信息的实现方式和关联关系的实现方式之间不必然存在绑定关系，本申请实施例可以是三者的可能的实现方式之间的任意组合。可以理解，上述示例中的小区选择参数可能的实现方式的替换、业务信息可能的实现方式的替换都属于本发明的保护范围。
下面将举例说明小区选择参数和业务信息的多种实现方式。可以理解，小区选择参数和业务信息可能的实现方式不限于以下示例中的实现方式，还可以包括本申请上述实施例中描述的实现方式，以及其他可能的实现方式。为了简洁表述，下文以一一对应关系作为示例进行举例。
示例一：多个业务速率范围与多个RSRP门限存在如表6所示的对应关系。在本示例中，业务速率范围为业务信息，RSRP门限为小区选择参数。
表6
示例二：多个业务类型与多个RSRP门限存在如表7所示的对应关系。在本示例中，业务类型为业务信息，RSRP门限为小区选择参数。
表7

示例三：多个业务类型与多组RSRP门限和RSRQ门限存在如表8所示的对应关系。在本示例中，业务类型为业务信息，RSRP门限和RSRQ门限为小区选择参数。
表8
存在一类实施方式，分别规定了多个小区选择参数与业务信息的关联关系。
示例一：多个业务类型与多个RSRP门限存在如表9-1所示的对应关系，多个业务类型与多个RSRQ门限存在如表9-2所示的对应关系，表9-1和表9-2所示对应关系均为一一对应关系。在本示例中，业务类型为业务信息；对应表9-1，RSRP门限为小区选择参数；对应表9-2，RSRQ门限为小区选择参数。
表9-1
表9-2

示例二：多个业务速率范围与多个RSRP门限存在如表10-1所示的对应关系，该对应关系为一一对应关系；多个业务类型与一个RSRQ门限存在如表10-2所示的对应关系，该对应关系为多对一关系。在本示例中，对应表10-1，业务速率范围为业务信息，RSRP门限为小区选择参数；对应表10-2，业务类型为业务信息，RSRQ门限为小区选择参数。
表10-1
表10-2
应理解，这类实施方式是本申请发明方案的多次应用，例如，上述示例中的表9-1所规定的关联关系是本申请发明方案的一次应用，上述示例中的表9-2、表10-2、表10-2所规定的关联关系均为本申请发明方案的一次应用。这类实施方式属于本发明的保护范围，这类实施方式属于本申请权利要求的保护范围。
S220，网络设备发送小区选择参数的一组或多组值。
可选的，网络设备可以通过广播信号发送小区选择参数的一组或多组值。例如，MIB、SIB1、其他***信息(other system information,OSI)、MAC层控制元素(MAC control element,MAC CE)等。或者，网络设备可以通过终端特定(UE-specific)的信令发送小区选择参数的一组或多组值。例如，RRC信令、MAC CE、下行控制信息(downlink control information,DCI)等。
可选的，关联关系是预定义的，或者，关联关系是网络设备发送的。
在一种实施方式中，关联关系可以是以预定义的方式被终端设备获知的。示例性的，关联关系是由网络设备和终端设备根据同一的预设规则定义的。
在一种实施方式中，关联关系是由网络设备在步骤S220中发送的。发送内容所承载的信号参照上述内容，在此不再赘述。
在一种实施方式中，关联关系是由网络设备在步骤S220以外的步骤S240中发送的。一个实施方式中，可以是通过广播信号或组播信号发送。步骤S240并未在图2中示出。可以理解，步骤S240可以在步骤S220之前，也可以在步骤S220之后，或者，也可以是与步骤S220同时进行的步骤。步骤S220与步骤S240发送内容所承载的信号参照上述内容，在此不再赘述。
S230，终端设备接收小区选择参数的一组或多组值，根据小区选择参数的一组或多组值进行小区选择。
具体的，终端设备接收小区选择参数的一组或多组值，确定关联关系，具体可以参考上述本申请实施例中的描述，在此不再赘述。相对应的，终端设备可以通过广播信号或终端特定的信令接收网络设备发送的小区选择参数的一组或多组值，具体可以参考上述描述，本申请在此不再赘述。
下面将详细介绍终端设备如何根据小区选择参数的一组或多组值进行小区选择。具体方法可以包括：终端设备根据所支持的一个或多个业务的业务信息与关联关系确定第一参数；第一参数为小区选择参数的一组或多组值中的一组值；终端设备根据第一参数进行小区选择。可选的，终端设备根据所支持的一个或多个业务中的一个特定业务的业务信息确定第一参数。可选的，终端设备根据所支持的一个或多个业务中业务服务质量需求最高的一个业务的业务信息确定第一参数。
第一参数为小区选择参数的一组或多组值中的一组值，例如一个RSRP门限和一个RSRQ门限为第一参数，其中，一个RSRP门限可以为小区选择参数中一个或多个候选RSRP门限中的一个，一个RSRQ门限可以为小区选择参数中一个或多个候选RSRQ门限中的一个。
应理解，本申请中终端设备根据所支持的一个或多个业务的业务信息与关联关系确定第一参数，只是一个示例。终端设备也可以是确定一个业务信息，再根据该业务信息与关联关系确定出第一参数。该确定的业务信息可以是当前需要执行的某个业务的业务信息，也可以是预设的某个业务的业务信息等。终端设备也可以确定一个业务速率，再根据业务速率与关联关系确定第一参数。该业务速率也可以是当前需要执行的某个业务的业务速率，也可以是预设的某个业务的业务速率等。本申请中，终端设备支持的业务，可以是终端设备支持的全部或部分业务，应理解，终端设备正在执行的或待完成的业务也属于终端设备支持的业务，一个或多个特定业务也属于终端设备支持的业务，相应的，一个或多个特定业务的业务需求，例如业务速率需求，也属于终端设备支持的业务的业务需求。
应理解，在本申请实施例中，小区选择参数的一组或多组值可以用于小区选择，也可以用于小区重选。终端设备可以根据第一参数进行小区选择，或进行小区重选。应理解，终端设备根据第一参数进行小区选择的过程，可以采用现有技术中的判断准则进行，也可以采用其他准则进行，本申请实施例对此不做限定。应理解，终端设备也可以根据小区选择参数进行其他操作。
在一个可能的实施方式中，业务速率范围为业务信息，RSRP门限为小区选择参数。终端设备根据 所支持的一个或多个业务的业务速率与关联关系确定第一参数；第一参数为小区选择参数中的一个或多个RSRP门限中的一个RSRP门限；终端设备根据第一参数进行小区选择。可选的，终端设备根据所支持的一个或多个业务中的一个特定业务的业务速率确定第一参数。可选的，终端设备根据所支持的，或当前支持的，或待执行的，或特定的，一个或多个业务中业务速率最高的一个业务的业务速率确定第一参数。
举例来说，终端设备接收当前小区的小区选择参数，根据小区选择参数确定当前小区的RSRP门限与业务速率范围存在如表11所示的关联关系。终端设备支持的两个业务的业务速率分别为3Mbps和8Mbps，则终端设备可以根据自身支持的两个业务的其中一个业务确定第一参数。一种可能的方式是，终端设备根据两个业务中业务速率最高的一个业务的业务速率确定第一参数，在本示例中，终端设备根据8Mbps确定第一参数为-80dBm。终端设备对当前小区的信号进行测量，并获得测量的RSRP为-85dBm。假设测量的RSRP高于第一参数时，终端才能选择驻留在当前的小区，则在本示例中，终端设备不可以选择驻留在当前小区。
表11
在又一个可能的实施方式中，业务类型为业务信息，RSRP门限为小区选择参数。终端设备根据所支持的一个业务的业务类型与关联关系确定第一参数；第一参数为小区选择参数中的一个或多个RSRP门限中的一个RSRP门限；终端设备根据第一参数进行小区选择。
举例来说，终端设备A和终端设备B接收当前小区的小区选择参数，根据小区选择参数确定当前小区的RSRP门限与业务类型存在如表12所示的关联关系。终端设备A支持的一个业务的业务类型为2，则终端设备A根据自身支持的业务类型2确定第一参数为-80dBm；终端设备B支持的一个业务的业务类型为1，则终端设备B根据自身支持的业务类型1确定第一参数为-90dBm。终端设备A对当前小区的信号进行测量，并获得测量的RSRP为-83dBm；终端设备B对当前小区的信号进行测量，并获得测量的RSRP为-85dBm。假设测量的RSRP高于第一参数时，终端才能选择驻留在当前的小区，则在本示例中，终端设备A不可以选择驻留在当前小区，终端设备B可以选择驻留在当前小区。
表12
在上述举例中，对于终端设备A，可以继续进行小区搜索，示例性地，如果当前网络中还存在另一个小区B，假设小区B所支持的业务速率等级以及相应的小区接入门限与小区A相同，假设终端设 备A在测量小区B的信号获得的RSRP为-75dBm，则终端设备A可以选择小区B驻留，当然也可以继续进行小区搜索。
本申请实施例通过将小区选择参数与业务信息相关联，使得支持不同业务的终端可以根据所支持的业务选择合适的小区进行驻留，解决了现有技术中小区选择参数与终端所支持的业务速率需求无法匹配的问题，从而提高了通信质量，改善了业务的服务质量，也可以解决网络覆盖性能下降的问题。
