Description

优化异系统变换的方法、终端设备及存储介质
本申请要求于2021年04月27日提交中国专利局、申请号为2021104587772、申请名称为“优化异系统变换的方法、终端设备及存储介质”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
本发明涉及通信领域，尤其涉及一种优化异系统变换的方法、终端设备及存储介质。
背景技术
长期演进(Long Term Evolution，LTE)到新无线(New Radio，NR)之间的异系统变换操作可以通过系统广播配置的重选参数触发小区重选，或者网络配置NR邻区测量事件，并且基于终端设备上报的测量报告触发切换，这些参数通常都是固定不变的。
5G NR使用的载波频率较高，因此相对于LTE覆盖能力要差些。通常在NR小区边缘区域LTE信号较强而NR小区信号较弱，而NR小区的重选优先级普遍会比LTE高，容易重选到NR小区。并且网络配置的NR邻区测量事件上报的门限值较低，网络容易把终端设备重定向或者切换到NR小区。而当NR小区信号变弱会容易出现无服务(Out of Service，OoS)或者又被网络重新切换到LTE小区。因此会容易出现频繁的4G、5G异系统变换操作，从而导致上网卡顿。

101、若所述终端设备满足第一条件，则所述终端设备提高第一门限值。
其中，所述第一条件为所述终端设备的驻留小区至少一次发生异系统变换，所述异系统变换为从第二网络制式小区变为第一网络制式小区后，又从所述第一网络制式小区变为所述第二网络制式小区，所述第一网络制式小区的通信优先级高于所述第二网络制式小区。即所述异系统变换可以理解为所述终端设备将驻留小区从第二网络制式小区变为第一网络制式小区后，又将驻留小区从所述第一网络制式小区变为所述第二网络制式小区。
可选的，所述第一条件为所述终端设备的驻留小区多次发生异系统变换。
一、驻留小区从第二网络制式小区变为第一网络制式小区
可选的，所述终端设备将驻留小区从第二网络制式小区变为第一网络制式小区，可以包括：所述终端设备通过重选、重定向或切换方式，将驻留小区从第二网络制式小区变为第一网络制式小区。
可选的，所述第一网络制式小区为新无线NR小区，所述第二网络制式小 区为长期演进LTE小区；所述终端设备将驻留小区从第二网络制式小区变为第一网络制式小区，可以包括：所述终端设备通过重选、重定向或切换方式，将驻留小区从所述LTE小区变为所述NR小区。
即终端设备的当前驻留小区为LTE小区，当终端设备当前为空闲态时，可以通过重选方式，将驻留小区从所述LTE小区变为所述NR小区；当终端设备当前为连接态时，可以通过重定向或切换方式，将驻留小区从所述LTE小区变为所述NR小区。
需要说明的是，如果第一网络制式小区为6G网络制式小区，那么第二网络制式小区可以为6G以下网络制式对应的小区(例如，5G、4G、3G、2G等网络制式对应的小区)。如果第一网络制式小区为5G网络制式对应的小区，那么第二网络制式小区可以为5G以下网络制式对应的小区(例如，4G、3G、2G等网络制式对应的小区)。
如果第一网络制式小区为4G网络制式对应的小区，那么第二网络制式小区可以为4G以下网络制式对应的小区(例如，3G、2G等网络制式对应的小区)。如果第一网络制式小区为3G网络制式对应的小区，那么第二网络制式小区可以为3G以下网络制式对应的小区(例如，2G等网络制式对应的小区)。
可以理解的是，上述的NR小区即为5G网络制式对应的小区，LTE小区即为4G网络制式对应的小区。
二、驻留小区从第一网络制式小区变为第二网络制式小区
可选的，所述将驻留小区从所述第一网络制式小区变为所述第二网络制式小区，可以包括：
所述终端设备根据网络设备发送的切换指示信息，将驻留小区从所述第一网络制式小区变为所述第二网络制式小区；或，
所述终端设备在无服务的情况下，将驻留小区从所述第一网络制式小区变为所述第二网络制式小区。
可选的，所述第一网络制式小区为新无线NR小区，所述第二网络制式小区为长期演进LTE小区；所述终端设备将驻留小区从所述第一网络制式小区变为所述第二网络制式小区，可以包括：
所述终端设备根据网络设备发送的切换指示信息，将驻留小区从所述NR 小区切换到所述LTE小区；或，
所述终端设备在无服务(Out of Service，OoS)的情况下，将驻留小区从所述NR小区掉网至所述LTE小区。
可以理解的是，终端设备的当前驻留小区为LTE小区，如果终端设备当前处于空闲态，将当前驻留小区从LTE小区重选到NR小区后；或者，如果终端设备当前处于连接态，将当前驻留小区从LTE小区重定向或者切换到NR小区后；当网络把终端设备的驻留小区从NR小区切换到LTE小区，或者终端OOS掉网到LTE小区。如图2A所示，为本申请实施例中终端设备进行异系统变换操作的一个示意图。如图2B所示，为本申请实施例中终端设备进行异系统变换操作的另一个示意图。
可选的，若通过重选方式，将驻留小区从所述第二网络制式小区变为所述第一网络制式小区，则所述第一门限值为重选门限值，所述重选门限值用于触发小区重选。
可选的，当终端设备的测量值大于该重选门限值时，触发所述终端设备进行小区重选。如果重选门限值提高的话，那么，当终端设备的测量值大于提高的重选门限值时，触发所述终端设备进行小区重选。
示例性的，若通过重选方式，将驻留小区从所述LTE小区变为所述NR小区，则所述第一门限值为重选门限值。例如：该重选门限值可以包括threshX-High-r15和threshX-HighQ-r15中的至少一项，那么，即可提高threshX-High-r15和threshX-HighQ-r15中的至少一项的门限值。
可选的，若通过重定向或切换方式，将驻留小区从所述第二网络制式小区变为所述第一网络制式小区，则所述第一门限值为测量上报门限值，所述测量上报门限值用于触发小区测量上报。
可选的，当终端设备的测量值大于该测量上报门限值时，触发所述终端设备进行小区测量上报。如果测量上报门限值提高的话，那么，当终端设备的测量值大于提高的测量上报门限值时，触发所述终端设备进行小区测量上报。
示例性的，若通过重定向或切换方式，将驻留小区从所述LTE小区变为所述NR小区，则所述第一门限值为测量上报门限值。例如：该测量上报门限值可以包括b1-ThresholdNR-r15，那么，即可提高b1-ThresholdNR-r15的门限 值。
示例性的，如图2C所示，为本申请实施例中优化异系统变换的方法的一个实施例示意图。在图2C所示中，初始参数n＝0，当终端设备的驻留小区从LTE小区重选、重定向或者切换到NR小区后，又被网络切换回LTE小区(排除演进的分组系统回退呼叫(EPS(Evolved Packet System)fallback call)的场景)，或者，直接OOS掉网到LTE小区时，n＝n+1，把第一门限值threshX-High-r15、threshX-HighQ-r15和b1-ThresholdNR-r15三个门限值中的一个或多个提高；进一步的，在定时器T(例如10分钟)期间维持提高后的第一门限值。定时器T超时后就可以重置第一门限值为原来的门限值。
n表示的是终端设备的驻留小区从LTE小区重选、重定向或者切换到NR小区后，又被网络切换回LTE小区，或者，直接OOS掉网到LTE小区的几次过程，每进行一次这样的过程，n的取值就加1。
如果第一门限值提高后，T时长(10分钟)内仍然还发生4G和5G异系统变换，则会继续按照流程再次提高第一门限值，直到不会发生4G和5G异系统变换。
示例性的，第一门限值的提高幅度可以是n*1，n*2，也可以是n*3等，还可以是其他的定值，单位是dB。
需要说明的是，不同网络制式的异系统变换，对应提高的第一门限值不一样。比如，终端设备从NR小区变为LTE小区，提高的第一门限值包括threshX-High-r15、threshX-HighQ-r15和b1-ThresholdNR-r15中至少一项的门限值。如果终端设备从4G小区变为3G小区，那么，提高的第一门限值就是与其对应的第一门限值。
可选的，若所述终端设备满足第二条件和第一条件，则所述终端设备提高第一门限值；所述第二条件包括以下条件至少之一：
所述终端设备的剩余内存小于预置内存阈值；
所述终端设备的当前温度大于预置温度阈值；以及，
所述终端设备的剩余电量小于预置电量阈值。
如果终端设备的剩余内容小于预置内存阈值，当前温度大于预置温度阈值，剩余电量小于预置电量阈值，此时，在终端设备的驻留小区至少一次从第 二网络制式小区变为第一网络制式小区后，又从所述第一网络制式小区变为所述第二网络制式小区的情况下，提高测量上报门限值，那么，满足测量上报门限值的小区通常会对应减少，节省终端设备的系统资源。
102、所述终端设备根据提高的第一门限值，触发小区重选或小区测量上报。
可选的，在所述第一门限值为重选门限值(例如：threshX-High-r15和threshX-HighQ-r15中的至少一项)的情况下，所述终端设备根据提高的所述第一门限值，触发小区重选，即进行小区重选。
可选的，在所述第一门限值为测量上报门限值(例如：b1-ThresholdNR-r15)的情况下，触发小区测量上报，即进行小区测量上报。
可选的，所述终端设备根据提高的第一门限值，触发小区重选或小区测量上报，可以包括：在第一预置时长内，所述终端设备根据提高的所述第一门限值，触发小区重选或小区测量上报。
可选的，所述方法还包括：若在第一预置时长内，所述终端设备发生异系统变换的次数大于预置阈值，则再次提高所述第一门限值；所述终端设备根据再次提高的所述第一门限值，触发小区重选或小区测量上报，所述再次提高的所述第一门限值大于所述提高的所述第一门限值。
可选的，所述终端设备根据再次提高的所述第一门限值，触发小区重选或小区测量上报，可以包括：在第二预置时长内，所述终端设备根据所述再次提高的所述第一门限值，触发小区重选或小区测量上报。其中，第一预置时长和第二预置时长可以相同，也可以不同。
可以理解的是，当网络把终端从NR小区切换到LTE小区，或者终端OOS掉网到LTE小区，意味着NR小区的信号变弱，那么应当要提高LTE小区到NR小区的重选门限值和B1NR测量上报的门限值，避免又被网络切到NR小区再次因为NR小区信号弱而掉到LTE小区，减少没必要的异系统变换操作。即可以根据实际异系统变换操作的情况动态调整重选门限值和/或测量上报门限值，减少没必要的异系统变换操作。
在本申请实施例中，若终端设备满足第一条件，则提高第一门限值；其中，所述第一条件为所述终端设备的驻留小区至少一次发生异系统变换，所述异系 统变换为从第二网络制式小区变为第一网络制式小区后，又从所述第一网络制式小区变为所述第二网络制式小区，所述第一网络制式小区的通信优先级高于所述第二网络制式小区。用于改善终端设备在弱信号环境下的网络稳定性，提高第一门限值，进而根据提高的第一门限值进行小区重选或小区测量上报，减少没必要的异系统变换操作，从而提高终端设备的用户体验。

可选的，处理模块301，具体用于根据提高的所述第一门限值，触发小区重选。
可选的，若通过重定向或切换方式，将驻留小区从所述第二网络制式小区变为所述第一网络制式小区，则所述第一门限值为测量上报门限值，所述测量上报门限值用于触发小区测量上报。
