Description

心跳包定时器的识别方法和设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种心跳包定时器的识别方法和设备。
背景技术
为了保持客户端与服务器之间长连接链路正常，承载该客户端的设备会设置一些周期性计时的定时器，每当定时器设定的计时终止时刻到达时，设备便会向服务器发送心跳包，发起与服务器之间的心跳包交互，以确认客户端与服务器之间长连接链路正常；这些用于为设备发送心跳包而计时的定时器为心跳包定时器；在心跳包定时器的计时终止时刻到达时，即使设备处于休眠状态，也会被唤醒；随着设备承载的具有不同功能的客户端(也可以为设备运行的应用或进程)越来越多，设备设置的心跳包定时器也不断增多，则导致设备唤醒频繁，严重影响设备的待机功耗。
为了降低设备的待机功耗，可以在一些场景下关闭心跳包定时器，或者增加心跳包定时器的计时周期的时长；由于设备设置的定时器较多，需要准确识别出心跳包定时器；而在现有技术中，通常是在一定时间内统计定时器的计时终止时刻到达的次数，当该次数超过预设值，便确定该定时器为心跳包定时器；可以想到的，设备设置的一些定时器可能仅用于实现设备的特定功能而重复计时，这些定时器并不是心跳包定时器，因此采用现有技术识别定时器是否为心跳包定时器时，容易出现识别错误，则会对设备的工作性能造成影响。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明心跳包定时器的识别方法实施例一的流程示意图。如图1所示，本实施例中的识别方法由设置了定时器的设备执行，该设备可以为移动终端、平板电脑及可穿戴设备，具体的识别方法如下：
S101、在设备传输的数据包中，确定与定时器的各个计时终止时刻对应的各个关联数据包。
所述设备传输的数据包为所述设备发送的数据包，或为所述设备接收的数据包，或为所述设备发送的数据包和接收的数据包；
考虑到在心跳包定时器的计时终止时刻，设备便会发送心跳包，本实施例为了准确识别定时器是否为心跳包定时器，需要获知该定时器在每一次的计时终止时刻是否发送了心跳包；可以理解的，设备发送、接收的各个数据包均是为设备内运行的进程或应用进行发送及接收的，例如常见的微信、QQ等移动终端上运行的应用，是通过设备内的软件和/或硬件发送、接收业务数据包、心跳包，设备仅执行发送或接收操作，不能直接获知发送或接收的数据包是否为心跳包，但由于在心跳包定时器的计时终止时刻起，设备会开始与对端设备进行心跳包的传输(包括向对端设备发送心跳包并接收对端设备反馈的心跳包)，则连续多次都在定时器的计时终止时刻起设备与对端设备进行了可能为心跳包的数据包的传输，该定时器才有可能为心跳包定时器，因此本实施例中将各个计时终止时刻和设备发送或接收的数据包结合起来，以确定该定时器是否为心跳包定时器；
考虑到在心跳包定时器的计时终止时刻，设备便会为运行的进程或应用发送心跳包，可选的，设备可以在发送的数据包中确定可能为心跳包的数据包；或者考虑到在心跳包定时器的计时终止时刻的附近，设备便会为运行的进程或应用接收对端设备反馈的心跳包，可选的，设备可以在接收的数据包中确定可能为心跳包的数据包；
但考虑到上述应用或进程的运行机制不同，这些应用或进程为了避免心跳包的发送时延，通常会在心跳定时器的计时终止时刻之前的稍早时刻便通知设备发送数据包，因此在客观时间真正到达心跳定时器的计时终止时刻时，设备会收到对端设备反馈的心跳包，因此为了避免因未监听到可能为心跳包的数据包，较优的，设备还可以监听发送和接收的全部数据包，并在设备发送和接收的全部数据包中确定可能为心跳包的关联数据包；该关联数据包与定时器之间存在关联关系；由于设备上运行的应用较多，可以根据所述设备发送和/或接收的各个数据包的信息，例如数据包中的IP(Internet Protocol，网络互连协议)号和端口号，获知该数据包是为某个应用发送或接收的，且 上述定时器也是为该应用设置的，则可确定该数据包是与该定时器是针对同一个应用来说的，则确定该数据包为与定时器存在关联关系；进一步的，考虑到心跳包是在心跳定时器的计时终止时刻附近发送或接收，则在所述设备发送和/或接收的全部数据包中，确定与所述定时器的各个计时终止时刻对应的各个关联数据包。
S102、根据各个关联数据包和所述定时器的各个计时终止时刻，判断所述定时器是否为所述设备为传输心跳包设置的心跳包定时器。
具体的，当设备确定在每一个定时器的计时终止时刻，设备均发送了与各个计时终止时刻对应的各个关联数据包，且各个关联数据包的格式、大小相似，则可以较高的准确率确定该定时器即为所述设备为传输心跳包设置的心跳包定时器；
或者可选的，考虑到关联数据包的接收时刻或发送时刻与该关联数据包对应的计时终止时刻之间的时间差越小，该关联数据包为心跳包的可能性越高，因此还可以根据各个关联数据包的接收时刻或发送时刻与各个计时终止时刻之间的时间差，以较高的准确率确定该定时器即为所述设备为传输心跳包设置的心跳包定时器。
本实施例中，考虑到在心跳包定时器的计时终止时刻，设备便会发送心跳包设备发送和/或接收数据包，因此结合设备发送和/或接收的全部数据包和定时器的各个计时终止时刻对应的各个关联数据包，可以以较高的准确率判断定时器是否为心跳包定时器，便于设备在不需要被频繁唤醒时，准确关闭心跳包定时器或延长心跳包定时器的计时时长，降低设备的功耗，且以较大可能的避免了因对定时器误判而影响了设备的其他性能的情况。
图2为本发明心跳包定时器的识别方法实施例二的流程示意图。如图2所示，本实施例是在图1所示的实施例的基础上，做出进一步的描述，具体包括：
S201、获知设备在定时器的当前计时终止时刻对应的时段内，传输的至少一个数据包和所述至少一个数据包的套接字。
在当前计时终止时刻对应的时段内，设备会监听设备发送或接收的至少一个数据包，并获取至少一个数据包的套接字，上述数据包的套接字(socket)用于描述该数据包的IP地址和端口；
上述当前计时终止时刻为随客观时间推移而变化的相对概念，例如客观时间到达T1时刻，且T1时刻为定时器的一个计时终止时刻，则对于到达T1时刻的客观时间来说，T1时刻为当前计时终止时刻，随着客观时间的推移，到达T2时刻，该T2时刻也为定时器的一个计时终止时刻，则对于到达T2时刻的客观时间来说，该T2时刻即为新的当前计时终止时刻。
S202、根据至少一个数据包的套接字，在至少一个数据包中确定所述当前计时终止时刻对应的至少一个候选关联数据包。
在当前计时终止时刻对应的时段内，监听到发送或接收的至少一个数据包，并获取至少一个数据包的套接字，根据至少一个数据包的套接字可以确定至少一个数据包分别是设备为哪个应用或进程发送或接收的，从而可确定至少一个与定时器存在关联关系的数据包，进一步的，由于至少一个与定时器存在关联关系的数据包是在当前计时终止时刻对应的时段内接收的，所述至少一个与定时器存在关联关系的数据包均为当前计时终止时刻对应的候选关联数据包。
S203、根据当前计时终止时刻和当前计时终止时刻对应的至少一个候选关联数据包的处理时刻，确定所述当前计时终止时刻对应的关联数据包。
在上述S202中确定的各个候选关联数据包中，若候选关联数据包为设备接收的数据包，该候选关联数据包的处理时刻为设备接收该候选关联数据包的接收时刻；若候选关联数据包为设备发送的数据包，该候选关联数据包的处理时刻为设备发送该候选关联数据包的发送时刻；
而上述当前计时终止时刻对应的关联数据包为在该当前计时终止时刻对应的各个候选关联数据包中，处理时刻与该计时终止时刻之间的差值最小的候选关联数据包；可以理解的，数据包的处理时刻与定时器的计时终止时刻之间的时间差越小，该数据包是设备在该定时器的计时终止时刻发送的心跳包的可能性越高，从而结合该数据包判断该定时器是否为心跳包定时器的准确率越高，因此本实施例是在计时终止时刻对应的各个候选关联数据包中，确定处理时刻与该计时终止时刻之间的差值最小的候选关联数据包为该计时终止时刻对应的关联数据包。
S204、根据当前计时终止时刻和当前计时终止时刻对应的关联数据包的处理时刻，获取所述当前计时终止时刻对应的信息素增量。
本实施例中，定时器的各个计时终止时刻中任意一个计时终止时刻对应 的信息素增量是根据
Figure PCTCN2014092714-appb-000007
确定的，i和N均为正整数，i的取值为所述当前计时终止时刻之前的各个计时终止时刻的序号，N的取值为所述当前计时终止时刻的序号；addi为第i个计时终止时刻对应的信息素增量，deltai为第i个计时终止时刻与第i个计时终止时刻对应的关联数据包的处理时刻之间的偏移量，deltai＝|whenElapsedi-netElapsedi|；whenElapsedi为第i个计时终止时刻，netElapsedi为第i个计时终止时刻对应的关联数据包的处理时刻，timeout用于表示容忍的最大偏移量(取值可以根据实际需要灵活设置)；THRESHOLD为第一预设值；-THRESHOLD为所述第二预设值；
具体的，addi为第i个计时终止时刻对应的信息素增量，第i个计时终止时刻对应的信息素增量越大，则第i个计时终止时刻对应的关联数据包为心跳包的可能性越大；在确定addi时，考虑到deltai越大，说明第i个计时终止时刻对应的关联数据包越不可能为心跳包，即deltai的大小与第i个计时终止时刻对应的关联数据包为心跳包的概率成反比，因此在deltai小于timeout时，采用1-deltai/timeout确定第i个计时终止时刻对应的信息素增量，在deltai大于timeout时，可以确定第i个计时终止时刻对应的关联数据包不为心跳包，为了在S205中挥发信息素，则采用-THRESHOLD/4确定第i个计时终止时刻对应的信息素增量。
S205、根据所述当前计时终止时刻对应的变量值和所述当前计时终止时刻之前的各个计时终止时刻对应的各个信息素增量，确定信息素余量。
上述信息素余量是根据

确定的，extra为预估信息素增量，其取值可根据实际需要灵活设置；S206、若信息素余量大于第一预设值，则确定所述心跳特征符合心跳定包定时器的特征。
S206、若信息素余量大于第一预设值，则确定所述定时器为心跳包定时器。
S207、若所述信息素余量小于第二预设值，则确定所述定时器不为心跳包定时器。
S208、若所述信息素余量小于所述第一预设值且大于所述第二预设值，则在下一个计时终止时刻到来时，返回执行所述S201。
具体的，由于连续多次都在定时器的计时终止时刻起设备与对端设备进行了可能为心跳包的数据包的传输，该定时器才有可能为心跳包定时器，所以本实施例是需要重复执行前述步骤S201～S208；举例来说，客观时间到达 T1时刻，且T1时刻为定时器的一个计时终止时刻，则对于客观时间上的T1时刻来说，T1时刻为定时器的当前计时终止时刻，则执行前述S201～S205，可以理解的，在T1时刻之前到达的各个计时终止时刻，对于其对应的客观时间来说，也是各个当前计时终止时刻；当由T1时刻起执行前述S201～S205，确定信息素余量大于第一预设值或信息素余量小于第二预设值，则说明根据当前计时终止时刻和当前计时终止时刻之前对应的各个关联数据包，能够判断出该定时器是否为心跳包定时器，且判断的结果的准确率较高；但当信息素余量小于所述第一预设值且大于所述第二预设值，则说明根据当前计时终止时刻和当前计时终止时刻之前对应的各个关联数据包，不能以较高的准确率判断出该定时器是否为心跳包定时器，也可以说，当前时刻收集的用于以较高的准确率判断该定时器是否为心跳包定时器所需的信息(即上述各个计时终止时刻及各个计时终止时刻对应的关联数据包的处理时刻)不够全面及完整，因此还需继续收集用于以较高的准确率判断该定时器是否为心跳包定时器所需的信息，则随着客观时间的推移，在T2时刻到来时，也即在下一个计时终止时刻到来时，将该下一个计时终止时刻作为新的当前计时终止时刻，返回执行S201。
另外，为了减小设备监控设备接收和/或发送的数据包的负担，且考虑到心跳包是在各个计时终止时刻附近发送或接收的，因此本实施例是在定时器的各个计时终止时刻对应的时段内监听设备接收和/或发送的全部数据包，上述计时终止时刻对应的时段可以为一个时刻点，由于一个时刻点在微分范畴中可以细分为无线多个点，则基于一个时刻点包含无限多个点，或者由于设备内部数据处理产生的时延，导致漏监听到可能为心跳包的数据包，上述计时终止时刻对应的时段为具有一定时长的时间段。
本实施例中，考虑到在心跳包定时器的计时终止时刻，设备便会发送心跳包设备发送和/或接收数据包，因此结合设备发送和/或接收的全部数据包和定时器的各个计时终止时刻对应的各个关联数据包，可以以较高的准确率判断定时器是否为心跳包定时器，便于设备在不需要被频繁唤醒时，准确关闭心跳包定时器或延长心跳包定时器的计时时长，降低设备的功耗，且以较大可能的避免了因对定时器误判而影响了设备的其他性能的情况。
图3为本发明心跳包定时器的识别方法实施例三的流程示意图。如图 3所示，本实施例是结合前述图1或图2所示的实施例，描述了一种上述识别方法的具体应用流程，具体如下：
S301、判断定时器的描述信息中是否有记录定时器为心跳包定时器，或不为心跳包定时器；若是，则停止；若否，执行S302。
S302、在所述定时器的当前计时终止时刻到来时，判断设备是否处于唤醒状态；若否，执行S311；若是，则在下一个计时终止时刻到来时，执行S303。
由于心跳包定时器在一个计时终止时刻到来时，若该设备处于唤醒状态，则设备会直接发送心跳包，但若该设备处于睡眠状态，在心跳包定时器的计时终止时刻到来时，设备会被唤醒以发送心跳包；而上述定时器的一个计时终止时刻到来时，设备处于唤醒状态的原因可能是因为该定时器的一个计时终止时刻到来，也有可能是设备为其他应用或进程设置的心跳包定时器将设备唤醒，或者设备正在传输业务数据包，也会处于唤醒状态；但若设备处于睡眠状态，且在上述定时器的计时终止时刻到来时，设备也未被唤醒，则可确定该定时器不是心跳包定时器。
在确定上述定时器不为心跳包定时器后，执行S311，在该定时器的描述信息中记录该定时器不为心跳包定时器，则在随后的时间里，当设备需要关闭心跳包定时器或延长心跳包定时器的计时时长时，不需执行下述各个步骤对该定时器进行识别，可直接确定该定时器不为心跳包定时器。
S303、在定时器的当前计时终止时刻对应的时段内，获取设备接收和/或发送的至少一个数据包和所述至少一个数据包的套接字。
S304、根据至少一个数据包的套接字，在至少一个数据包中确定所述当前计时终止时刻对应的至少一个候选关联数据包。
S305、根据当前计时终止时刻和当前计时终止时刻对应的至少一个候选关联数据包的处理时刻，确定所述当前计时终止时刻对应的关联数据包。
S306、根据当前计时终止时刻和所述当前计时终止时刻对应的关联数据包的处理时刻，获取所述当前计时终止时刻对应的信息素增量。
S307、根据所述当前计时终止时刻对应的信息素增量和所述当前计时终止时刻之前的各个计时终止时刻对应的各个信息素增量，确定信息素余量。
S308、若信息素余量大于第一预设值，则确定所述定时器为心跳包定时 器。
执行S308后，执行S311；
S309、若所述信息素余量小于第二预设值，则确定所述定时器不为心跳包定时器。
执行S309后，执行S311；
S310、若所述信息素余量小于所述第一预设值且大于所述第二预设值，则在下一个计时终止时刻到来时，返回执行所述S303。
S311、更新定时器的描述信息。
若是执行S308后执行了S311，则更新的描述信息是该定时器为心跳包定时器；若执行S302或S309后执行了S311，则更新的描述信息是该定时器不为心跳包定时器。
本实施例中，考虑到在心跳包定时器的计时终止时刻，设备便会发送心跳包设备发送或接收数据包，因此结合设备发送和/或接收的数据包和定时器的各个计时终止时刻对应的各个关联数据包，可以以较高的准确率判断定时器是否为心跳包定时器，便于设备在不需要被频繁唤醒时，准确关闭心跳包定时器或延长心跳包定时器的计时时长，降低设备的功耗，且以较大可能的避免了因对定时器误判而影响了设备的其他性能的情况。
需要说明的是，设备可以为多个应用或进程设置至少一个定时器；设备设置的任意一个定时器均可采用前述各个方法实施例，以判断该定时器是否为心跳包定时器。
