Description

半静态调度控制方法、装置及基站 技术领域
本文涉及通信领域，尤其涉及一种半静态调度控制方法、装置及基站。
背景技术
在LTE(Long Term Evolution，长期演进)系统中，取消了全部电路域的话音业务，而代之以数据域的VoIP业务。针对VoIP这类数据包大小比较固定，到达时间间隔满足一定规律的实时性业务，LTE引入了一种新的调度方式：半静态调度(SPS)，即为特定业务设计的、需要激活/释放资源的、在固定时刻使用预先分配资源而在其他时刻进行动态调度(重传)的一种调度方法。同时，为了使终端能够尽可能的省电，LTE应用了不连续接收(DRX)的方法。DRX可以让终端处于激活(active)状态和睡眠(sleeping)状态，终端周期性的醒来进行物理下行控制信道(PDCCH)的接收与操作，而不必时时监测物理下行控制信道，从而达到省电的目的。当SPS与DRX同时应用于LTE的语音业务时，为了保证语音通话的质量，同时确保终端尽量省电，对SPS的准确控制就显得尤为重要，否则可能导致连续的丢包，影响语音通话的质量。

本发明的实施方式
下面结合附图对本发明实施方式作详细说明。
实施例一：
请参见图1所示，本实施例提供的半静态调度控制方法包括：
步骤101：配置半静态调度配置时间窗口；
配置的半静态调度配置时间窗口的时间起点大于等于不连续接收持续时间(Onduration)起点，半静态调度配置时间窗口的时间终点小于等于不连续接收持续时间(Onduration)终点；也即配置的半静态调度配置时间窗口可以等于(或采用)不连续接收持续时间的时间窗口，也可以配置为在不连续接收持续时间的时间窗口内，以保证半静态调度的激活在不连续接收的持续时间内进行，也即确保半静态调度的激活一定是在终端激活状态进行的。
步骤102：检测到半静态调度激活条件满足；
步骤103：判断当前时刻是否在半静态调度配置时间窗口内；如是，转至步骤104；如否，转至步骤105；
步骤104：进行半静态调度的配置完成半静态调度的激活。
步骤105：结束。
上述步骤101中，可选地，配置半静态调度配置时间窗口的时间起点等于不连续接收持续时间起点，半静态调度配置时间窗口的时间终点等于不连续接收持续时间终点；也即配置半静态调度配置时间窗口可以等于(或采用) 不连续接收持续时间的时间窗口。因为在不连续接收的Sleeping时刻终端不检测PDCCH，因此半静态调度激活配置应该在不连续接收的ACTIVE时刻。同时由于PDCCH漏检、反馈解析错误等异常，基站维护的ACTIVE时刻与终端维护的难以严格对齐，因此为了以确保终端能够检测，初始时半静态调度配置时间窗口以不连续接收持续时间的起始时刻为起点，以不连续接收持续时间的结束时刻为结束点。当满足激活半静态调度条件时，再通过半静态调度配置时间窗口来确定能否马上配置半静态调度，即当前时刻在半静态调度配置时间窗口内时，则可以配置，当前时刻不在半静态调度配置时间窗口内时，不能配置。
上述步骤102中的半静态调度激活条件可以由不同的用户或运营商根据不同的应用场景设定并设定相应的算法来检测完成。在此不再赘述。
在经上述步骤104之后完成半静态调度激活后，本实施例还包括对是否需要对半静态调度进行重新激活进行检测。并根据检测结果判定是否需要进行半静态调度重激活。请参见图2所示，在上述步骤104之后，还包括：
步骤106：判断半静态调度重激活条件是否满足，如是，转至步骤107；如否，转至步骤105；
步骤107：判断当前时刻是否在当前设置的半静态调度配置时间窗口内；如是，转至步骤108；如否，转至步骤105；
步骤108：进行半静态调度重激活配置。
上述步骤106中的半静态调度重激活条件也可以由不同的用户或运营商根据不同的应用场景设定并设定相应的算法来检测完成。本实施例中的判断半静态调度重激活条件是否满足包括：判断基站与终端的不连续接收状态是否对齐，如未对齐，则认为满足重激活条件，需要对半静态调度重激活。这主要是考虑到由于PDCCH存在错误检测，终端可能接收到并非指向自身的半静态调度配置，并错误的应用到自身，从而尝试在错误的资源上接收下行数据或者发送上行数据。这种误检不仅浪费了终端的不连续接收省电效果，而且还对其他终端产生了干扰。因此，本实施例在对半静态调度激活后，还包括检测这种误检是否发生并对该错误进行纠正。可以设置一个终端级别的定时器。在定时器时间内统计终端的半静态调度调度的错包情况进而判决基 站与终端的不连续接收状态是否对齐。对于一个半静态调度周期新传的混合自动重传(HARQ)进程，如果反馈结果是DTX(也即基站在协议确定的空口时刻没有收到终端反馈的ACK或NACK信息)，说明终端没有检测到半静态调度周期新传时刻的数据，则可能存在基站与终端不连续接收状态未对齐的可能，如果DTX的数目超过设定的判断门限，则认为基站与终端不连续接收状态未对齐，此时则需要进行半静态调度的重激活处理。
在本实施例中，当判断基站与终端的不连续接收状态未对齐时，还可对半静态调度配置时间窗口进行缩小处理；当判断基站与终端的不连续接收状态对齐时，还可对半静态调度配置时间窗口进行扩大处理；动态的调整半静态调度配置时间窗口更利于提升半静态调度的控制效率，提升用户体验的满意度。当然，应当理解的是本实施例中也可以采用一个固定的半静态调度配置时间窗口。本实施例中在对半静态调度配置时间窗口进行缩小处理之前，还可包括判断该半静态调度配置时间窗口当前是否已经降低为预设的最小值，如是，则不需要再进行缩小处理；如否，则可按照预设的规则进行缩小处理；在对半静态调度配置时间窗口进行扩大处理之前，也包括判断半静态调度配置时间窗口当前是否为预设的最大值；如是，则不再需要进行扩大处理；如否，则可以按照预设规则进行扩大处理。本实施例中的预设的最小值可为不连续接收持续时间的时间值；本实施例中的预设的最大值可为不连续接收的长周期时间值。
下面结合一个完整的控制过程对本发明实施例作说明，设不连续接收配置的持续时间起始时刻为M，结束时刻为N，不连续接收周期长度为C。
请参见图3所示，包括：
步骤301：终端接入后使能半静态调度和不连续接收功能；
步骤302：配置半静态调度配置时间窗口，可配置的半静态调度配置时间窗口的时间起点等于不连续接收持续时间起点，半静态调度配置时间窗口的时间终点等于不连续接收持续时间终点；
步骤303：终端满足半静态调度激活条件；
步骤304：判断当前时刻是否在半静态调度配置时间窗口内，即保证半 静态调度激活信息只有在不连续接收持续时间内才能进行；如是，转至步骤305；如否，转至步骤310；
步骤305：激活半静态调度；
步骤306：启动定时器，收集HARQ的DTX反馈信息；
步骤307：定时器超时，判断DTX反馈数是否高于预设判定门限，如否，则进行步骤308；如是，则进行步骤309；
步骤308：未检测到未对齐情况，将半静态调度配置时间窗口扩大一个子帧，即窗口结束位置加1，重新启动定时器，转至步骤306；
步骤309：检测到未对齐情况，在半静态调度配置时间窗口结束位置不等于N时，将半静态调度配置时间窗口收缩一个子帧，即窗口结束位置减1；同时重新激活半静态调度，转至步骤306；
基站侧可以通过与终端的交互信息来判断是否出现了不对齐的现象，如基站下行数据的harq反馈，若终端未反馈，则可以认为终端未收到基站的下行数据，若连续出现未反馈情况，可以认为两侧状态未对齐；再如基站给终端授权了上行资源(DCI0，下行控制信息)，终端在对应时频域位置没有上发数据，则可以认为终端未收到基站下发的DCI0，若连续出现未上发数据，可以认为两侧状态未对齐。
步骤310：结束。
综上，本发明实施例在半静态调度与不连续接收同时应用于LTE的语音业务的场景下，能够很好的保证语音通话的质量，同时确保终端尽量省电。

时间窗口配置模块1设置为：配置半静态调度配置时间窗口，半静态调度配置时间窗口的时间起点大于等于不连续接收持续时间起点，半静态调度 配置时间窗口的时间终点小于等于不连续接收持续时间终点；也即配置的半静态调度配置时间窗口可以等于(或采用)不连续接收持续时间的时间窗口，也可以配置为在不连续接收持续时间的时间窗口内，以保证半静态调度的激活在不连续接收的持续时间内进行，也即确保半静态调度的激活一定是在终端激活状态进行的；可选地，配置的半静态调度配置时间窗口的时间起点等于不连续接收持续时间起点，半静态调度配置时间窗口的时间终点等于不连续接收持续时间终点；也即配置半静态调度配置时间窗口可以等于(或采用)不连续接收持续时间的时间窗口。

请参见图7所示，半静态调度控制装置还包括时间窗口调整模块4，设置为：在对齐判断子模块31判断基站与终端的不连续接收状态未对齐时，对半静态调度配置时间窗口进行缩小处理，在对齐判断子模块31判断基站与终端的不连续接收状态对齐时，对半静态调度配置时间窗口进行扩大处理。动态的调整半静态调度配置时间窗口更利于提升半静态调度的控制效率，提升用户体验的满意度。当然，应当理解的是本实施例中也可以采用一个固定的半静态调度配置时间窗口。本实施例中在对半静态调度配置时间窗口进行缩小处理之前，还包括判断该半静态调度配置时间窗口当前是否已经降低为预设的最小值，如是，则不需要再进行缩小处理；如否，则可按照预设的规则进行缩小处理；在对半静态调度配置时间窗口进行扩大处理之前，也包括判断半静态调度配置时间窗口当前是否为预设的最大值；如是，则不再需要进行扩大处理；如否，可以按照预设规则进行扩大处理。本实施例中的预设的最小值可为不连续接收持续时间的时间值；本实施例中的预设的最大值可为不连续接收的长周期时间值。
