一种释放无线资源控制连接的方法、终端设备及存储介质
相关申请的交叉引用
本申请要求在2019年07月09日提交中国专利局、申请号为201910615568.7、申请名称为“一种释放无线资源控制连接的方法、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
本申请涉及通信技术领域，尤其涉及一种释放无线资源控制连接的方法、终端设备及存储介质。
背景技术
随着互联网的快速发展，越来越多的终端设备需要与网络设备进行通信。在终端设备与网络设备进行通信之前，终端设备需先与网络设备之间建立无线资源控制(radio resource control，RRC)连接。当终端设备与网络设备之间不需要进行通信时，可断开RRC连接，即释放RRC连接。
现有技术中，终端设备有数据需要传输时，与网络设备建立RRC连接，当数据传输完成后，终端设备向网络设备发送释放RRC连接的指令，网络设备接收到该指令后，释放RRC连接。在该方式中，终端设备每次发送或接收数据时，都必须重新建立RRC连接，会导致系统信令流量的显著增加。
为了解决信令流量增加的问题，提出了快速休眠的方案，即当终端设备没有需要传输的数据时，处于寻呼信道(paging channel，PCH)状态，即终端设备与网络之间不存在专用物理信道连接，而终端设备也不可以使用任何上行物理信道，仅可以根据非连续接收(discontinuous reception，DRX)参数来响应寻呼(Paging)。在该PCH状态下，由于终端设备仍然能响应网络的Paging消息，因此，功耗仍然较大。
发明内容
本申请提供一种释放无线资源控制连接的方法、终端设备及存储介质，用于降低通信装置的功耗。
第一方面，本申请提供一种释放无线资源控制连接的方法，该方法包括：确定当前第一数据包传输完成的第一时刻，确定预测的N个第二时刻中与第一时刻最接近的第二时刻，若确定目标第二时刻与第一时刻之间的间隔时长大于预设时长，则向网络设备发送指示信息，指示信息用于指示网络设备释放无线资源控制连接，目标第二时刻为预测的传输下一个数据包的时刻，下一个数据包与第一数据包为相邻传输的两个数据包。
该方法可由通信装置执行，通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片系统。示例性地，通信设备可为终端设备。
基于该方案，若目标第二时刻与第一时刻之间的间隔时长大于预设时长，那说明其它的第二时刻与第一时刻之间的间隔时长更长。也就是说，当前第一数据包传输完成后，距 离下一次传输数据包的时长比较长，通信装置向网络设备发送指示信息，网络设备将RRC连接断开，即通信装置进入空闲(IDLE)状态，从而可减小通信装置的功耗。
在一种可能的实现方式中，可针对N个数据包中的每个数据包：确定数据包的传输完成时刻，确定数据包所属的业务类型，根据业务类型与传输周期的对应关系，确定数据包对应的传输周期，根据数据包的传输完成时刻和数据包对应的传输周期，预测传输数据包所属的业务类型的下一个数据包的第二时刻，这样基于N个数据包可获得N个预测的第二时刻，其中，N个数据包中包括第一数据包。
进一步地，可先确定数据包对应的传输完成时刻所属的时间段，并确定终端设备的当前状态，根据数据包传输完成时刻所属的时间段、终端设备的当前状态、以及数据包所属的业务类型，查询预存的对应关系，得到该数据包的传输周期，其中，对应关系包括数据包传输完成时刻所属的时间段、终端设备的当前状态、数据包所属的业务类型以及传输周期之间的关系，终端设备的当前状态包括灭屏状态或者亮屏无操作状态。
在一种可能的实现方式中，预设时长可以为终端设备维护的定时器的设定时长的正整数倍。

本申请中，可根据是否存在RRC连接，将终端设备划分为空闲模式和连接模式。具体终端设备可处于四种状态：空闲(IDLE)状态，终端设备与网络之间无任何连接，因此功耗较低，典型的电流消耗为1-2mA。专用信道(dedicated channel，DCH)状态，网络设备为终端设备分配专有物理信道，用于大量用户数据的传输，因此功耗也较大，典型的电流消耗为150-700mA。前向接入信道(forward access channel，FACH)状态，终端设备和网络之间不存在专用物理信道连接，终端设备在下行方向将继续监视FACH传输信道，而在上行方向可以使用公共的或共享传输信道(如随机接入信道(random access channel，RACH))进行少量用户数据的传输，因此，功耗也相对比较低，典型的电流消耗为100-130mA。寻呼信道(paging channel，PCH)状态，终端设备与网络之间不存在专用物理信道连接，而终端设备也不可以使用任何上行物理信道，可以根据非连续接收(discontinuous reception，DRX)参数来响应Paging，因此，也存在一定的功耗，比IDLE状态的功耗高。四种状态下终端设备的电流消耗可参见图2所示的电流消耗。应理解，可以用电流消耗来表示终端设备的功耗。
进一步，四种状态之间可以发生切换。IDLE状态下，终端设备需要进行数据包传输时，则通过发送RRC连接建立请求(RRC connection setup request)给网络设备请求建立RRC连接，RRC连接建立完成后进入DCH状态。DCH状态下，当用户数据传输完毕后，会有一个定时器(timer)用来监听数据包传输。当timer超时，则认为当前没有大量数据需要传输，则进入FACH状态。FACH状态下，当数据包传输完毕后，会有一个timer用来监听数据传输。当timer超时，则认为当前没有数据包需要传输，则进入IDLE状态。需要说明的是，timer都是网络(NW)配置的，取值通常是10的整数倍，例如，10s、20s、30s、40s等。当终端设备处于PCH状态，能响应网络的Paging消息。当收到Paging消息或者用户发起呼叫时，进入FACH状态，进行少量数据包的传输。由此可知，终端设备在timer超时前，都会存在功耗。
鉴于上述存在的问题，下面结合上述图1b所示的终端设备的结构介绍本申请实施例提供的技术方案。图3示例性示出了本申请实施例提供的一种释放无线资源控制连接的方法流程示意图。在下文的介绍中，传输包括发送和接收，即终端设备传输数据包是指：终端设备在发送数据包，或者终端设备在接收数据包。该方法包括如下步骤：
步骤301，终端设备确定当前第一数据包传输完成的第一时刻。具体地，在通过移动通信模块151或者无线通信模块152发送完成每个数据包时，处理器110可以在内部存储器121中记录发送完成当前数据包的时刻。
在一种可能的实现方式中，可以是处理器110确定终端设备中显示屏194的当前状态 为灭屏或亮屏无操作时，再确定当前第一数据包传输完成的第一时刻。由于显示屏194处于灭屏或亮屏无操作的状态下的终端设备中数据包的传输有一定的规律性，因此，显示屏194处于灭屏或亮屏无操作的状态下释放掉RRC连接时，不会对终端设备传输数据包造成影响。
步骤302，终端设备确定预测的N个第二时刻中与第一时刻最接近的第二时刻为目标第二时刻。具体地，处理器110预测移动通信模块151或者无线通信模块152传输第一数据包的下一个相邻的数据包的时刻作为目标第二时刻。
本申请中，处理器110可在检测到显示屏194处于灭屏状态以及亮屏无操作的状态下，分别记录终端设备内各业务类型的数据包的传输时刻，并将记录的各业务类型的数据包的传输时刻存储在内部存储器121中或者通过外部存储器接口120存储于外部存储器中。表1示例性地示出了终端设备记录的传输的数据包的信息，其中，终端设备传输的数据包的信息包括终端设备的状态、业务类型、起始传输时刻和传输完成时刻等。

灭屏 … … …
亮屏无操作 QQ心跳包 5:00 5:01

亮屏无操作 … … …
进一步地，处理器110还可能会针对某些业务设置有防火墙通行规则，具体针对哪些业务类型设置防火墙通行规则，可由处理器110自行确定。例如，处理器110可针对推送业务设置有防火墙通行规则，具体可以为隔3min放行数据包一次，或者在一个轮询过程(例如00:00-23:59为一个轮询过程)中，前6小时(即00:00-06:00)每隔60min放行数据包一次，之后每隔5min放行数据包一次。也就是说，防火墙的通行规则可以周期性的，也可以是非周期性的。应理解，不同的业务可能对应的不同的防火墙规则。
处理器110可基于上述存储于内部存储器121中或者通过外部存储器接口120存储于外部存储器中的传输的数据包的信息，统计出各业务类型的周期。为了使得统计的结果更精确，可分时段进行统计。如表2所示，示例性示出了一种传输的数据包的统计信息，统计信息包括终端设备的状态、业务类型、时间段以及传输周期之间的关系，其中，终端设备的状态包括灭屏状态或者亮屏无操作状态，传输周期是基于表1中前一次传输完成的时刻与当前传输起始时刻之间的时间差的统计结果确定的。也就是说，表2中包括业务类型与传输周期的对应关系，其中，一种业务类型在不同的时间段或者终端设备状态不同的情况下，对应传输周期也可能不同。示例性地，针对不同的时间段，可以分别统计显示屏194处于灭屏和亮屏无操作状态下传输的数据包的统计信息。在一种可能的实现方式中，也可 将该统计信息存储于数据库中。该传输的数据包的统计信息可反应出用户能够该终端设备的习惯。
表2 一种传输的数据包的统计信息
Figure PCTCN2020101158-appb-000003
需要说明的是，表2所示防火墙的通行规则是周期性的。若防火墙的通行规则是非周期的，可以单独记录防火墙的通行规则，即可记录防火墙每次放行数据包的时刻。也可以理解为，防火墙的通行规则也可作为一种业务类型。
还需要说明的是，当终端设备中有新的业务类型出现时，处理器110可以对新的业务类型传输数据包的时刻进行统计，并在表2中增加新的业务类型的统计信息。
当处理器110确定通过移动通信模块151或者无线通信模块152发送完成数据包后，可根据表2的统计信息，预测出传输的该数据包所属的业务类型的下一个数据包的第二时刻。具体过程可为：确定数据包的传输完成时刻，确定数据包所属的业务类型，根据业务类型与传输周期的对应关系，确定数据包对应的传输周期，根据数据包的传输完成时刻和数据包对应的传输周期，预测传输数据包所属的业务类型的下一个数据包的第二时刻。例如，第二时刻＝传输完成时刻经过第一传输周期后的时刻。若传输完成时刻为1:00，第一周期T＝10min，则第二时刻＝1:10。
为了提供确定出的第二时刻的精确性，可先确定数据包对应的传输完成时刻所属的时间段，并确定终端设备的当前状态，根据数据包传输完成时刻所属的时间段、终端设备的当前状态、以及数据包所属的业务类型，查询预存的对应关系(如表2所示)，得到数据包的传输周期，其中，对应关系包括数据包传输完成时刻所属的时间段、终端设备的当前状态、数据包所属的业务类型以及传输周期之间的关系。具体地，可以是处理器110先确定传输完成时刻所属的时间段，以及检测到显示屏194当前状态，再从存储于内部存储器121中或者通过外部存储器接口120存储于外部存储器的业务类型与传输周期的对应关系中，确定出该数据包所属的业务类型在该时段内和该状态下对应的传输周期。
示例性地，如下以预测传输第一数据所属的业务类型的下一个第一数据包的第二时刻为例说明，参见图4，为本申请提供的一种预测传输第一数据所属的业务类型的下一个第一数据包的第二时刻的方法流程示意图。该方法包括：
步骤401，终端设备确定第一数据所属的第一业务类型。具体地，处理器110可根据第一数据包的端口号对应的应用，确定第一数据包对应第一业务类型。
步骤402，终端设备可根据业务类型与传输周期的对应关系，确定出第一业务类型对应的第一传输周期。
步骤403，终端设备根据第一传输周期和第一时刻，预测传输第一数据包所属的第一业务类型的下一个第一数据包的第二时刻。
例如，第二时刻＝第一时刻经过第一传输周期后的时刻。若第一时刻为1:00，第一周期T＝10min，则第二时刻＝1:10。
在一种可能的实现方式中，针对每个传输完成的数据包，处理器110均可预测出传输该数据包所属的业务类型的下一个数据包的第二时刻，进一步，可将预测出的全部第二时刻均记录在存储于内部存储器121中或者通过外部存储器接口120存储于外部存储器中，从而在当前第一数据包传输完成后，可从存储于内部存储器121中或者通过外部存储器接口120存储于外部存储器中记录的全部第二时刻中，确定出第一时刻最接近的第二时刻。
如下以灭屏状态下的微信心跳包的传输为例来说明。示例性地，若处理器110确定当前微信心跳包传输完成的第一时刻为01:06，又由于01:06属于[00:00-06:00]的时段，处理器110调用存储于内部存储器121中或者存储于外部存储器中的业务类型与传输周期的对应关系，确定微信心跳包对应的第一传输周期为5min，可预测出传输下一个微信心跳包的第二时刻为01:11。也就是说，处理器110确定当前微信心跳包传输完成之后，在01:11进行下一次传输微信心跳包传输。
步骤303，终端设备确定目标第二时刻与第一时刻之间的间隔时长是否大于预设时长，若大于，执行步骤304；若不大于，执行步骤305。具体地，可以是处理器110确定目标第二时刻与第一时刻之间的间隔时长是否大于预设时长。
其中，预设时长可为终端设备维护的定时器的设定的时长的正整数倍，例如，可以是定时器的设定时长的2倍或者3倍。
为了便于方案的理解，如下以业务类型包括微信心跳包、QQ心跳包和推送业务为例说明。示例性地，处理器110确定在01:00有一个推送业务的数据包传输完成，由于01:00属于[00:00-06:00]的时段，通过调用存储于内部存储器121中或者存储外部存储器中的业务类型与传输周期的对应关系，确定推送业务的周期为8min，可预测出传输下一个推送业务的数据包的时刻(即第二时刻)为01:08；同样地，确定在01:04有一个QQ心跳包传输 完成，可预测出传输下一个QQ心跳包的时刻(也称为第二时刻)为01:09。若当前是微信心跳包传输完成，对应的第一时刻为01:06，又由于微信心跳包对应的第一传输周期为5min，可预测出传输下一个微信心跳包的第二时刻为01:11。即处理器110可将三个第二时刻(分别为01:08、01:09和01:11)均记录于内部存储器121中或者通过外部存储器接口120记录于外部存储器，处理器110可确定01:08为与第一时刻最接近的第二时刻，也就是说，处理器110确定在01:06通过移动通信模块151或者无线通信模块152完成数据包的传输后，会在01:08传输下一个数据包(即推送业务的数据包)。
进一步，处理器110还可确定与第一时刻最接近的第二时刻与第一时刻之间的时间间隔时长为(01:08-01:06)＝2min。
步骤304，终端设备向网络设备发送指示信息，指示信息用于指示网络设备释放无线资源控制连接。具体地，处理器110可通过移动通信模块151或者无线通信模块152向网络设备发送指示信息。
在该步骤304中，指示信息可以是终端设备与网络设备预先约定的，也可以是协议预定义的，本申请对此不做限定。此处，指示信息可以是一个索引，该索引可指示出网络设备需要释放RRC连接；或者，该指示信息也可以是一个指示字符，该指示字符可指示出网络设备需要释放RRC连接。指示信息的具体形式也可以是其它任意可能的形式，本申请对此不做下限定。
步骤305，终端设备保持当前无线资源控制连接。也可以理解为，在处理器110确定与第一时刻最接近的第二时刻与第一时刻之间的间隔时长不大于预设时长时，不需要做处理，维持当前的无线资源控制连接即可。
从上述步骤301至步骤305可以看出，若目标第二时刻与第一时刻之间的间隔时长大于预设时长，那说明其它的第二时刻与第一时刻之间的间隔时长更长。也就是说，当前第一数据包传输完成后，距离下一次传输数据包的时长比较长，终端设备向网络设备发送指示信息，网络设备将RRC连接断开，即终端设备进入IDLE状态，从而可减小终端设备的功耗。
为了提高确定出的最接近的第二时刻的精确性，示例性地，终端设备在判断是否释放无线资源控制连接的周期开始后，通过移动通信模块151或者无线通信模块152开始传输数据包，针对每一种业务类型，处理器110可以针对传输的前几个(例如前3个)数据包不去预测第二时刻，待移动通信模块151或者无线通信模块152开始传输完成第4个数据包后，再开始预测第4个数据包的第二时刻。进一步，可先确定传输的前3个数据包的传输周期与存储于内部存储器121中或者存储外部存储器中的该数据包对应的业务类型所述对应的传输周期比较接近时，再开始预测传输第4个数据包的第二时刻。
