Description

一种避免终端寻呼与系统消息并发冲突的方法、系统 技术领域
本公开涉及消息冲突检测技术，尤指一种避免终端寻呼与系统消息并发冲突的方法、系统、终端和存储介质。
背景技术
窄带物联网(Narrow Band Internet of Things,简称为NB-IoT)是移动技术领域的一个新兴分支，其系统消息(System Information，简称为SI)周期性地在系统消息窗内发送，周期内偏移与SI编号、初始偏移有关。
终端寻呼搜索空间也是周期性的，周期内偏移与UE_ID、周期内寻呼子帧数等有关，并且寻呼周期与系统消息周期存在整数倍关系，且可能相等，这样就存在系统消息窗与寻呼搜索空间位置始终重叠的情况。若终端不支持同时并行接收不同业务，且在空闲态始终采取寻呼优先的策略，可能存在终端一直无法接收到更新的系统消息或邻区的系统消息的风险。

本公开实施例提供了一种避免终端寻呼与系统消息并发冲突的方法，如图1所示，所述方法包括：
S101，接收读系统消息SI请求，在当前终端寻呼周期结束后，判断系统消息SI的接收情况；
作为一种实现方式，接收读系统消息请求后，如果当前正在监测寻呼搜索空间，则在等待寻呼监测结束后开始接收系统消息；如果当前寻呼周期已经结束，则可直接接收系统消息；可以在等待一个SI接收周期后，判断SI的接收情况；
S102，当SI没有全部接收且所述读系统消息请求未超时，计算后续终端寻呼周期与未接收的SI窗的位置关系；
S103，当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠；
作为一种实现方式，所述当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠，包括：
当未接收的SI窗个数为1时，若所述未接收的SI窗与计算时间点之 后的终端寻呼周期有重叠，则将与SI窗有重叠的终端寻呼周期的下一个与SI窗无重叠的终端寻呼周期的起始点，作为下一次终端寻呼周期的寻呼时刻点。
当未接收的SI窗个数为n个，未接收的SI窗分别表示为SIx1,SIx2,…,SIxn，n大于或等于2时；当计算时间点之后第一个完整的SI窗为SIxi，若所述SIxi窗与计算时间点之后的终端寻呼周期有重叠，则将与SIxi窗有重叠的终端寻呼周期的下一个与SIxi窗无重叠的终端寻呼周期的起始点PFi，作为根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点，i初始值为1，每计算得到根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点PFi后，i增加1直至i等于n；取计算得到的PF1,…,PFn中的最大值为下一次终端寻呼周期的寻呼时刻点。
本公开实施例能够实现寻呼搜索空间与系统消息发送窗口位置重叠时系统消息优先接收。
下面以具体的应用示例对本公开实施例进行解释说明。
终端进入空闲态后启动寻呼与系统消息窗冲突检测流程，在收到读系统消息请求并经过一个寻呼周期以及配置的SI最大周期时长之后，判断SI接收情况，若SI已全部接收成功或读系统消息超时，则不计算后续终端寻呼周期与SI窗位置关系，并继续监测是否要接收系统消息；若SI没有全部接收且所述读系统消息请求未超时，计算后续终端寻呼周期与未接收的SI窗的位置关系。
假设当前剩余n个SI未收到，分别表示为SIx1,SIx2,…,SIxn。用SIstart，SIend分别表示计算时间点之后第一个完整的SIxi窗的起、止时刻。PageStart1表示下一次终端寻呼周期的寻呼时刻点，PageStart 2表示再下一个周期，依次类推。PFi表示根据SIxi延迟后的下一次终端寻呼周期的寻呼时刻点，i初始值为1，每计算得到根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点PFi后，i增加1直至i等于n。本应用示例分下面两种情况来判断终端寻呼周期与未接收的SI窗的位置关系，并得出推迟 后的下一次终端寻呼周期的寻呼时刻点。
第一种情况，SI窗长小于寻呼周期，如图2所示。
如果未接收的SI窗与第一个寻呼起点PageStart1重叠，或者未接收的SI窗在第一个寻呼起点和第二个寻呼起点之间，则推迟下一次寻呼起点到PageStart2；如果未接收的SI窗与第二个寻呼起点重叠，则推迟下一次寻呼起点到PageStart3；同理，如果未接收的SI窗在第二个寻呼起点和第三个寻呼起点之间，则推迟下一次寻呼起点到PageStart3；如果未接收的SI窗与第三个寻呼起点重叠，则推迟下一次寻呼起点到PageStart4；以此类推；如果后续终端寻呼周期与未接收的SI窗不存在重叠，下一次寻呼从PageStart1开始正常接收寻呼信号。
第二种情况，SI窗长大于或等于寻呼周期且小于两个寻呼周期，如图3所示；
如果未接收的SI窗仅与第一个寻呼起点PageStart1重叠，则推迟下一次寻呼起点到PageStart2；如果未接收的SI窗同时与第一个寻呼起点和第二个寻呼起点重叠，或者未接收的SI窗仅与第二个寻呼起点重叠，则推迟下一次寻呼起点到PageStart3；如果未接收的SI窗同时与第二个寻呼起点和第三个寻呼起点重叠，则推迟寻呼起点到PageStart4；以此类推；如果后续终端寻呼周期与未接收的SI窗不存在重叠，下一次寻呼从PageStart1开始正常接收寻呼信号。
经过上述判断后得到推迟后的寻呼时间点PFi，可以保证接收到一个完整SI窗内的所有重复子帧。对于剩余多个SI的情形，若存在PFi不等于PageStart1的情况，则要将PageStart1更新为PFi，PageStart2、3依次延后，重复上述步骤得到对应的PFn，最后取PF1,…,PFn中的最大值为下一次终端寻呼周期的寻呼时刻点。
根据得到的下一次终端寻呼周期的寻呼时刻点设置寻呼启动定时器，并启动空闲态系统消息接收，如果剩余n个SI接收后存在解码错误的SI，继续尝试接收剩余解码失败的SI。在下一次寻呼搜索空间监测完后继续判 断SI接收情况。
本公开实施例还提供了一种避免终端寻呼与系统消息并发冲突的系统，如图4所示，所述系统包括：
系统消息接收模块401，设置为接收读系统消息请求，在当前终端寻呼周期结束后，判断系统消息SI的接收情况；作为一种实现方式，接收读系统消息请求后，如果当前正在监测寻呼搜索空间，则在等待寻呼监测结束后开始接收系统消息；如果当前寻呼周期已经结束，则可直接接收系统消息；可以在等待一个SI接收周期后，判断SI的接收情况；
冲突检测模块402，设置为当SI没有全部接收且所述读系统消息请求未超时，计算后续终端寻呼周期与未接收的SI窗的位置关系；当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠。
作为一种实现方式，所述冲突检测模块402，设置为当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠，包括：
当未接收的SI窗个数为1时，若所述未接收的SI窗与计算时间点之后的终端寻呼周期有重叠，则将与SI窗有重叠的终端寻呼周期的下一个与SI窗无重叠的终端寻呼周期的起始点，作为下一次终端寻呼周期的寻呼时刻点。
当未接收的SI窗个数为n个，未接收的SI窗分别表示为SIx1,SIx2,…,SIxn，n大于或等于2时；当计算时间点之后第一个完整的SI窗为SIxi，若所述SIxi窗与计算时间点之后的终端寻呼周期有重叠，则将与SIxi窗有重叠的终端寻呼周期的下一个与SIxi窗无重叠的终端寻呼周期的起始点PFi，作为根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点，i初始值为1，每计算得到根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点PFi后，i增加1直至i等于n；
取计算得到的PF1,…,PFn中的最大值为下一次终端寻呼周期的寻呼 时刻点。

    取计算得到的PF1,…,PFn中的最大值为下一次终端寻呼周期的寻呼时刻点。
  4. 一种避免终端寻呼与系统消息并发冲突的系统，包括：
    系统消息接收模块，设置为接收读系统消息请求，在当前终端寻呼周期结束后，判断系统消息SI的接收情况；
    冲突检测模块，设置为当SI没有全部接收且所述读系统消息请求未超时，计算后续终端寻呼周期与未接收的SI窗的位置关系；当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠。
  5. 根据权利要求4所述的避免终端寻呼与系统消息并发冲突的系统，其中，冲突检测模块，设置为当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠，包括：
    当未接收的SI窗个数为1时，
    若所述未接收的SI窗与计算时间点之后的终端寻呼周期有重叠，则将与SI窗有重叠的终端寻呼周期的下一个与SI窗无重叠的终端寻呼周期的起始点，作为下一次终端寻呼周期的寻呼时刻点。
  6. 根据权利要求4所述的避免终端寻呼与系统消息并发冲突的系统，其中，冲突检测模块，设置为当计算得到后续终端寻呼周期与未接收的SI窗存在重叠，将后续终端寻呼周期延迟以避免所述重叠，包括：
    当未接收的SI窗个数为n个，未接收的SI窗分别表示为SIx1,SIx2,…,SIxn，n大于或等于2时；
    当计算时间点之后第一个完整的SI窗为SIxi，若所述SIxi窗与计算时间点之后的终端寻呼周期有重叠，则将与SIxi窗有重叠的终端寻呼周期的下一个与SIxi窗无重叠的终端寻呼周期的起始点PFi，作为根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点，i初始值为1，每计算得到根据SIxi窗延迟后的下一次终端寻呼周期的寻呼时刻点PFi后，i增加1直至i等于n；
    取计算得到的PF1,…,PFn中的最大值为下一次终端寻呼周期的寻呼时刻点。
  7. 一种计算机可读存储介质，，所述介质存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现如权利要求1至3中任一项所述的避免终端寻呼与系统消息并发冲突的方法的步骤。
  8. 一种避免终端寻呼与系统消息并发冲突的终端，包括：存储器，用于存储计算机可执行指令；处理器，用于执行所述计算机可执行指令，以实现权利要求1至3中任一项所述的避免终端寻呼与系统消息并发冲突的方法的步骤。
