小区重选的方法及设备

本申请主张在2020年1月19日在中国提交的中国专利申请号No.202010057898.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信技术领域，尤其涉及一种小区重选的方法及设备。
背景技术
空闲态的终端通过网络配置的频率优先级进行小区重选，选择优先驻留的频率，频率优先级配置的方式有两种：
(1)在***消息中广播频率优先级，广播的频率优先级对于小区内所有终端都一样，无法区分用户
(2)通过专用信令(例如：无线资源控制释放(RRC release)消息)配置频率优先级。
在***无线通信技术(fourth generation，4G)时代，专用频率优先级主要用于网络进行负载均衡，将用户卸载到较为空闲的载波上。第五代无线通信技术(5th generation，5G)时代，随着终端类型多样化，终端支持的业务的多样化，专用的频率优先级的使用也更加多样和灵活。
例如，5G中引入的切片，同一个终端可以支持多个切片业务，小区也可以支持多个切片业务，终端仅能接入自己支持的切片的小区。通过相关技术，网络根据终端支持的切片，为终端配置了专用的频率优先级(例如将支持该切片的频率优先级提升)，但是当终端移动其他小区中，按照现有协议，终端将继续使用专用的频率优先级，但是新小区中，可能已不支持该切片。因此，此时仍然使用该专用的频率优先级无法起到原来的目的，且可能导致网络负载不均衡。
再例如，在多无线接入技术双连接(MR-DC)场景中，以4G无线接入网与5G NR的双连接(E-UTRA-NR Dual Connectivity，EN-DC)为例，5G 终端和普通4G终端在空闲态均驻留在4G LTE网络中，但是网络可以为EN-DC终端配置和LTE终端不同的专用的频率优先级(例如将支持EN-DC的LTE载波频率优先级提升)。但是当EN-DC终端移动到其他小区，按照现有协议，终端将继续使用专用的频率优先级，但是在新小区中，可能已没有5G覆盖。因此，此时仍然使用专用的频率优先级终端也无法工作在5G模式下，且可能导致网络负载不均衡。
由此可知，配置的频率优先级无法满足多种终端类型和多样业务的灵活性。

参见图2，本公开的一些实施例提供一种小区重选的方法，该方法的执行主体可以为终端，具体步骤包括：步骤201。
步骤201：从网络设备接收频率优先级，以及与所述频率优先级对应的频率优先级原因、或者所述频率优先级是否生效信息、或者所述频率优先级的生效条件信息、或者所述频率优先级的索引信息；
其中，所述频率优先级，以及所述频率优先级原因、或者所述频率优先级是否生效信息、或者所述频率优先级的生效条件、或者所述频率优先级的索引信息用于终端进行小区重选。
在本公开的一些实施例中，频率优先级用于表示终端采用某种频率进行小区重选的优先程度。示例性地，频率优先级的内容可以包括：一个或多个频率和该频率的优先级，其中优先级可以通过数值表示，比如，数值越大优先级越高，数值越小优先级越低。
例如，频率优先级可以包括：1.8GHz频率优先级为2(较高)，1.9GH频率优先级为1(较低)，即优先采用1.8GHz的频率进行小区重选；又例如，频率优先级可以包括：4.9GHz频率优先级为2(较高)，2.6GHz频率优先级为1(较低)，即优先采用4.9GHz的频率进行小区重选。
需要说明的是，上述频率优先级的内容仅为示例，本公开的一些实施例对频率优先级的内容不做具体限定。
在本公开的一些实施例中，频率优先级原因用于表示配置频率优先级的原因，例如，负载均衡、切片或MR-DC等。
在本公开的一些实施例中，频率优先级是否生效信息用于表示频率优先级是否生效的相关信息，例如，负载均衡、切片或MR-DC等。
在本公开的一些实施例中，频率优先级的生效条件用于表示频率优先级是否生效的条件，例如，负载均衡、切片或MR-DC等。
在本公开的一些实施例中，频率优先级的索引信息用于表示频率优先级的标识，例如：f1频率优先级为1，f2频率优先级为2，对应频率优先级索引信息为索引0；f1频率优先级为2，f2频率优先级为1，对应频率优先级索引信息索引1。
在本公开的一些实施例中，可选地，通过***消息或者专用信令从网络设备接收频率优先级，以及与所述频率优先级对应的频率优先级原因、或者所述频率优先级是否生效信息、或者所述频率优先级的生效条件信息、或者所述频率优先级的索引信息。
在本公开的一些实施例中，如果所述频率优先级，以及与所述频率优先级对应的频率优先级原因、或者所述频率优先级是否生效信息、或者所述频率优先级的生效条件信息、或者所述频率优先级的索引信息是通过广播的***消息接收到的，则根据所述频率优先级进行小区重选需要满足的条件还包括：所述终端的驻留小区保持不变。
进一步地，当终端移动到其他小区，即驻留小区发生改变，则广播的频率优先级失效，终端读取新的驻留小区***消息中的频率优先级，根据该频率优先级进行小区重选。
在本公开的一些实施例中，一个频率优先级原因、或者是否生效信息、或者生效条件信息、或者索引信息可以与第一个或多个频率优先级对应，如果满足该优先级原因则终端可以使用基于该优先级原因配置的频率优先级。
示例性地，所述频率优先级原因、或者是否生效信息、或者生效条件信息可以包括以下一项或多项：
(1)负载均衡；
考虑网络的负载均衡设置的频率优先级，例如，网络将某带宽较大的时分双工(Time-Division Duplex，TDD)频率的优先级设置较高，用来承载更多的用户，进行负载均衡；
(2)终端支持的切片类型(或者简称为切片)；
考虑终端支持切片类型设置的频率优先级，例如，终端支持超高可靠与低时延通信(Ultra Reliable&Low Latency Communication，URLLC)切片业务，网络将支持URLLC切片业务的频率优先级设置较高，让终端优先驻留在支持URLLC切片业务的频率上；
(3)网络部署的MR-DC频段组合和/或终端支持的MR-DC频段组合(或者简称为MR-DC)。
考虑网络部署的MR-DC频段组合和终端支持MR-DC频段组合设置的频率优先级，例如，网络部署了LTE 1.8GHz+NR 2.6GHz的NSA频段组合，且该终端也同时支持该MR-DC频段组合，则网络将1.8GHz LTE频率的优先级设置较高，让MR-DC终端优先驻留1.8GHz频率上，若优先驻留在其他频率上，将导致进入连接态后需要切换至1.8GHz频率才能配置MR-DC，造成额外的切换开销和时延。
例如，2.6GHz频率优先级为2(较高)，4.9GHz频率优先级为1(较低)，频率优先级原因为负载均衡。
又例如，4.9GHz频率优先级为2(较高)，2.6GHz频率优先级为1(较低)，频率优先级原因为切片。
又例如，1.8GHz频率优先级为2(较高)，1.9GH频率优先级为1(较低)；频率优先级原因为MR-DC。
在本公开的一些实施例中，图2所示的方法还可以包括：根据所述终端的能力信息和/或网络设备发送的指示信息，以及所述频率优先级原因、或者所述频率优先级是否生效信息、或者所述频率优先级的生效条件信息、或者所述频率优先级的索引信息，确定在小区重选时使用的频率优先级。
可选地，所述指示信息可以指示以下一项或多项：(1)本小区和/或邻区是否支持MR-DC；(2)本小区和/或邻区支持的切片类型；(3)本小区和/或邻区是否支持预设的专用网络；(4)本小区和/或邻区支持的专用网络类型；(5)所述终端采用的频率优先级信息。

方式4：如果所述频率优先级原因、或者所述频率优先级的生效条件信息表示：负载均衡或默认，所述终端接收到本小区和/或邻区支持的切片类型，且所述终端不支持切片，则将与所述负载均衡或默认对应的频率优先级确定为所述在小区重选时使用的频率优先级；
方式5：如果所述频率优先级原因、或者所述频率优先级的生效条件信息表示：负载均衡或默认，所述终端接收到本小区和/或邻区支持MR-DC，且所述终端不支持所述MR-DC，则将与所述负载均衡或默认对应的频率优先级确定为所述在小区重选时使用的频率优先级；
方式6：如果所述频率优先级原因、或者所述频率优先级的生效条件信息表示：负载均衡或默认，所述终端未接收所述指示信息，则将与所述负载均衡或默认对应的频率优先级确定为所述在小区重选时使用的频率优先级。
在本公开的一些实施例中，可以根据终端是否接收到网络设备发送的频率优先级激活信息，采用不同的方式确定在小区重选时使用的频率优先级。
方式1：如果接收到网络设备发送的频率优先级激活信息，则根据所述频率优先级激活信息和所述频率优先级原因、或者所述频率优先级是否生效信息、或者所述频率优先级的生效条件信息、或者所述频率优先级的索引信息，确定在小区重选时使用的频率优先级；
示例性地，步骤A：终端接收网络发送的频率优先级和频率优先级索引信息；例如：f1频率优先级为1，f2频率优先级为2，对应频率优先级索引信息为索引0；f1频率优先级为2，f2频率优先级为1，对应频率优先级索引信息索引1；步骤B：终端接收网络发送的频率优先级激活信息；例如：接收到频率优先级激活信息为索引1，表示终端采用索引1的频率优先级作为小区重选频率优先级，即(f1频率优先级为2，f2频率优先级为1)。
方式2：如果没有接收到网络设备发送的频率优先级激活信息，则采用默认的频率优先级作为小区重选频率优先级。

其中，该生效时间可以是时间点或者时间段，例如，频率优先级的生效时间未到期则表示可以使用该频率优先级；频率优先级的生效时间到期则表示不可以使用该频率优先级。例如，专用信令配置的频率优先级有生效时间，在生效时间内，终端采用专用信令中的频率优先级进行小区重选；过了生效时间之后，专用频率优先级失效，终端采用***消息广播中的频率优先级进行小区重选。
