Description

数据包处理方法和相关设备 技术领域
本发明涉及通信技术领域，具体涉及数据包处理方法和相关设备。
背景技术
目前4G网络技术基于长期演进(LTE，Long Term Evolution)制式接入方式构建，带来低延迟和高网速体验的同时，由于网络拓扑结构、覆盖率和永远在线特性等等因素，使得支持LTE制式的移动终端在数据传输和待机等功耗体验方面不佳，在一定程度上限制了其广泛应用。
时下较突出问题是LTE网络的网际互联协议(IP，Internet Protocol)数据包影响移动终端的待机功耗问题。例如LTE网络具备不同于3G网络的永远在线特性，断开数据业务后不对移动终端分组数据协议(PDP，Packet Data Protocol)上下文去激活，而仅对移动终端的演进分组系统(EPS，Evolved Packet System)承载(Bearer)进行去激活，因此，在网络上移动终端还始终有IP地址作为其识别。
其中，在网络上移动终端还始终有IP地址作为其识别的情况下，当移动终端的数据业务断开(数据业务断即数据业务未处于联网状态)后，移动终端的调制解调器(Modem)仍然可能接收到来自网络的大量IP数据包，现有技术中移动终端的调制解调器通常会将接收的任何IP数据包都直接转发给移动终端的应用处理器(Appellation Processor)，这使得在数据业务断开后移动终端的应用处理器仍然可能经常被无故唤醒，而这就会造成移动终端电量被大量无故消耗，进而影响用户产品体验。

其中，调制解调器确定所述移动终端的数据业务的联网状态的方式可能是多种多样的，举例来说，例如在移动终端的PDP上下文处于激活状态且移动终端存在EPS Bearer的情况下可确定移动终端的数据业务处于联网状态，在移动终端不存在EPS Bearer的情况下则可以确定移动终端的数据业务未处于联网状态。
可选的，在本发明的一些可能的实施方式中，进一步的，移动终端的调制解调器若确定所述移动终端的数据业务处于联网状态，所述调制解调器可检测所述IP数据包的目的IP地址是否与所述移动终端的其中一个本地(Local)IP地址相同；若检测到所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址均不同，所述调制解调器根据所述IP数据包的传输协议类型对所述IP数据包进行处理，其中，在若检测到所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址均不同的情况下，所述调制解调器不向所述移动终端的应用处理器转发所述IP数据包。
研究和实践发现，在若检测到所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址均不同的情况下，通常可认为所述IP数据包对于所述移动终端的应用处理器而言可能是无效，因此，在检测到所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址均不同的情况下，所述调制解调器不向所述移动终端的应用处理器转发所述IP数据包，而由所述调制解调器根据所述IP数据包的传输协议类型对所述IP数据包进行处理，使得对于应用处理器 而言无效的一些IP数据包可以被调制解调器阻断，这有利于减少在数据业务未断开的情况下移动终端的应用处理器对无效IP数据包的处理，进而有利于降低移动终端的待机功耗，进而提升用户产品体验。
可选的，在本发明的一些可能的实施方式中，若检测到所述IP数据包的目的IP地址与所述移动终端的其中1个本地IP地址相同，所述调制解调器可向所述移动终端的应用处理器转发所述IP数据包。其中，在移动终端的数据业务处于联网状态的情况下，若检测到所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址相同，通常可认为所述IP数据包对于所述移动终端的应用处理器而言可能是有效。一个移动终端可能具有多个本地IP地址，例如移动终端语音业务、彩信业务和数据业务可能对应不同本地IP地址。
可选的，在本发明的一些可能的实施方式中，若确定所述移动终端的数据业务未处于联网状态，所述调制解调器在根据所述IP数据包的传输协议类型对所述IP数据包进行处理之后，控制所述移动终端进入待机状态。其中，在所述移动终端的数据业务未处于联网状态的情况下，那么移动终端被垃圾包(所述IP数据包)触发进入链接(CONNECTED)状态，则无需等待网络超时即可控制移动终端进入待机(IDLE)状态，这样也有利于进一步降低移动终端待机耗电量。
其中，调制解调器根据所述IP数据包的传输协议类型对所述IP数据包进行处理的方式可能是多种多样的，例如所述IP数据包的传输协议类型不同，调制解调器对所述IP数据包进行处理的方式也可能不同。
其中，举例来说，所述调制解调器根据所述IP数据包的传输协议类型对所述IP数据包进行处理，例如可包括：若所述IP数据包的传输协议类型为用户数据报协议(UDP，UserDatagram Protocol)，所述调制解调器可以丢弃所述IP数据包。
又举例来说，调制解调器根据所述IP数据包的传输协议类型对所述IP数据包进行处理，例如可以包括：若所述IP数据包的传输协议类型为因特网控制报文协议(ICMP，Internet Control Message Protocol)，所述调制解调器向网络发送所述IP数据包的应答(answer)数据包。其中，ICMP数据包通常为服务器 用于检测某IP地址是否有效的PING包。
又举例来说，调制解调器根据所述IP数据包的传输协议类型对所述IP数据包进行处理可包括：若所述IP数据包的传输协议类型为TCP，所述调制解调器可向网络发送响应所述IP数据包的复位(RST，Reset)数据包。例如若所述IP数据包来自网络中的服务器，调制解调器可向网络中的服务器发送响应所述IP数据包的复位数据包。其中，服务器接收到上述复位数据包之后通常会断开该服务器与移动终端之间的Socket连接，而服务器断开Socket连接之后就不会再向移动终端下发IP数据包，这样有利于节约网络资源，也有利于降低移动终端待机耗电量。
具体例如，调制解调器发送响应所述IP数据包的复位数据包可包括：所述调制解调器将所述IP数据包的目的IP地址作为所述调制解调器中的虚拟网卡的IP地址(例如，所述调制解调器可以修改所述调制解调器中的虚拟网卡的IP地址，以使得所述调制解调器中的虚拟网卡的修改后的IP地址与所述IP数据包的目的IP地址相同)，其中，所述虚拟网卡的端口列表中不包含与所述目的IP地址匹配的端口记录(例如所述虚拟网卡的端口列表可为空端口列表)，所述调制解调器向所述虚拟网卡的TCP/IP协议栈输入所述IP数据包，以触发所述虚拟网卡的协议栈在接收到所述IP数据包之后向网络发送响应所述IP数据包的复位数据包。其中，在所述虚拟网卡的端口列表中不包含与所述目的IP地址匹配的端口记录的情况下，所述虚拟网卡的TCP/IP协议栈在接收到所述IP数据包之后向网络发送响应所述IP数据包的复位数据包。其中，引入虚拟网卡可看成是镜像Socket实现机制，通过巧妙配置虚拟网卡的端口列表使得虚拟网卡的端口列表中不包含与所述目的IP地址匹配的端口记录，这就可触发所述虚拟网卡的TCP/IP协议栈在接收到所述IP数据包之后主动向网络发送响应所述IP数据包的复位数据包，进而可很好的避免由于不回应服务器引起的服务器反复重传TCP数据包，进而有利于避免出现移动终端反复被唤醒的现象。
为便于更好的理解和实施本发明实施例的上述方案，下面结合更具体的应用场景进行进一步说明。
请参见图2-a～图2-d，图2-a为本发明的另一个实施例提供的另一种数据包 处理方法的流程示意图。图2-b和图2-c为本发明的实施例提供的两种网络部署架构的示意图。
其中，图2-a举例所示，本发明的另一个实施例提供的另一种数据包处理方法可包括：
S201、移动终端的Modem创建虚拟网卡。
其中，虚拟网卡的PORT列表可为空PORT列表，虚拟网卡的初始IP地址为无效IP地址(例如虚拟网卡的初始IP地址为“0,0,0,0”)。
S202、移动终端的Modem从AP获取IP路由信息表，所述IP路由信息表包含移动终端的部分或全部本地IP地址(Local-IP地址)。
S203、移动终端的Modem接收来自网络的IP数据包。
例如在图2-b所示网络架构中，移动终端的Modem可接收来自网络的服务器的IP数据包。例如在图2-c所示网络架构中，移动终端的Modem可接收来自网络的另一移动终端的IP数据包。
S204、移动终端的Modem确定移动终端的数据业务的联网状态。
若确定移动终端的数据业务处于联网状态，则执行步骤S205。
若确定移动终端的数据业务未处于联网状态，则执行步骤S207。
例如若移动终端的PDP上下文处于激活状态且移动终端存在EPS Bearer则认为移动终端的数据业务处于联网状态，若移动终端不存在EPS Bearer则可认为移动终端的数据业务未处于联网状态。
S205、移动终端的Modem在IP路由信息表查找是否存在与接收到的IP数据包的目的IP地址匹配的记录(即所述IP数据包的目的IP地址是否与所述移动终端的其中1个本地IP地址相同)。
若是，则执行步骤S206。
若否，则执行步骤S207。
S206、移动终端的Modem向移动终端的AP转发上述IP数据包。
其中，若IP路由信息表中查找到了与接收到的IP数据包的目的IP地址匹配的记录(即所述IP数据包的目的IP地址与所述移动终端的其中1个本地IP地址相同)，可认为所述IP数据包为正常数据业务流量。
其中，若IP路由信息表中未查找到与接收到的IP数据包的目的IP地址匹配的记录(即所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址均不相同)，可认为所述IP数据包可能为非正常数据业务流量。
S207、移动终端的Modem确定上述IP数据包的传输协议类型。
若确定上述IP数据包的传输协议类型为ICMP，则执行步骤S208。
若确定上述IP数据包的传输协议类型为UDP，则执行步骤S209。
若确定上述IP数据包的传输协议类型为TCP，则执行步骤S210。
S208、移动终端的Modem向网络发送响应所述IP数据包的answer数据包。
S209、移动终端的Modem丢弃所述IP数据包。
S210、移动终端的Modem将所述IP数据包的目的IP地址作为所述调制解调器中的虚拟网卡的IP地址(例如，移动终端的Modem可以修改所述Modem中的虚拟网卡的IP地址，以使得所述Modem中的虚拟网卡的修改后的IP地址与所述IP数据包的目的IP地址相同)，其中，由于所述虚拟网卡的端口列表可为空端口列表，因此，所述虚拟网卡的端口列表中不包含与所述IP数据包的目的IP地址匹配的端口记录。
移动终端的Modem向虚拟网卡的TCP/IP协议栈输入所述IP数据包，以触发所述虚拟网卡的协议栈在接收到所述IP数据包之后向网络发送响应所述IP数据包的复位数据包。其中，在所述虚拟网卡的端口列表中不包含与所述目的IP地址匹配的端口记录的情况下，所述虚拟网卡的TCP/IP协议栈在接收到所述IP数据包之后向网络发送响应所述IP数据包的复位(RST)数据包。
其中，引入虚拟网卡可看成是镜像Socket实现机制，通过巧妙配置虚拟网卡的端口列表使得虚拟网卡的端口列表中不包含与所述目的IP地址匹配的端口记录，这就可触发所述虚拟网卡的TCP/IP协议栈在接收到所述IP数据包之后主动向网络发送响应所述IP数据包的复位数据包，进而可很好的避免由于不回应服务器引起的服务器反复重传TCP数据包，进而有利于避免出现移动终端反复被唤醒的现象。
可选的，在本发明的一些可能的实施方式中，若确定所述移动终端的数据业务未处于联网状态，所述调制解调器在根据所述IP数据包的传输协议类型对 所述IP数据包进行处理之后，控制所述移动终端进入待机状态。其中，在所述移动终端的数据业务未处于联网状态的情况下，那么移动终端被垃圾包(所述IP数据包)触发进入链接(CONNECTED)状态，则无需等待网络超时即可控制移动终端进入待机(IDLE)状态，这样也有利于进一步降低移动终端待机耗电量。
请参见图2-d，图2-d举例示出了本实施例方案与传统方案相比的一种节能效果。传统方案中Modem直接透传无效IP数据包到AP导致AP唤醒，而AP确无法处理该IP数据包使得其无故浪费电量。LTE制式下，Modem每次与网络的交互都需要进入CONNECTED高功耗状态(普通待机功耗的15～25倍)，该状态持续时间通常在10～30S不等，传统方案因一个无用的IP数据包导致Modem无法进入DISCONNECTED状态。传统方案中，由于AP没有处理IP数据包，如果IP数据包是TCP包，那么服务器得不到回应会认为移动终端没有收到该包，会进行3～15次重传，无形中将垃圾包的数量放大，进一步消耗待机功耗；实测传统方案发现移动终端待机功耗可能由理论的5～15mA增加到30～50mA，严重影响用户体验。而实施本实施例方案，可以极大的降低移动终端功耗，较大的提升用户体验。
可以看出，本实施例中的技术方案中，当移动终端的Modem在接收来自网络的网际互联协议IP数据包，移动终端的Modem确定所述移动终端的数据业务的联网状态，若确定移动终端的数据业务未处于联网状态，由Modem根据所述IP数据包的传输协议类型对所述IP数据包进行处理，并且由于在确定所述移动终端的数据业务未处于联网状态的情况下，所述Modem不向所述移动终端的应用处理器转发所述IP数据包，因此对于应用处理器而言无效的一些IP数据包可以被Modem阻断，可使得在数据业务断开后移动终端的应用处理器被无故唤醒的可能性极大降低，有利于极大减少应用处理器对无效IP数据包的处理，进而有利于降低移动终端的待机功耗，进而提升用户产品体验。
请参见图3，图3为本发明的另一个实施例提供的另一种数据包处理方法的流程示意图。其中，图3举例所示，本发明的另一个实施例提供的另一种数据包处理方法可包括：

S302、移动终端的Modem接收来自网络的IP数据包。
S303、移动终端的Modem确定移动终端的数据业务的联网状态。
若确定移动终端的数据业务处于联网状态，则执行步骤S304。
若确定移动终端的数据业务未处于联网状态，则执行步骤S306。
例如若移动终端的PDP上下文处于激活状态且移动终端存在EPS Bearer则认为移动终端的数据业务处于联网状态，若移动终端不存在EPS Bearer则可认为移动终端的数据业务未处于联网状态。
S304、移动终端的Modem在IP路由信息表查找是否存在与接收到的IP数据包的目的IP地址匹配的记录(即所述IP数据包的目的IP地址是否与所述移动终端的其中1个本地IP地址相同)。
若是，则执行步骤S305。
若否，则执行步骤S306。
S305、移动终端的Modem向移动终端的AP转发上述IP数据包。
其中，若IP路由信息表中查找到了与接收到的IP数据包的目的IP地址匹配的记录(即所述IP数据包的目的IP地址与所述移动终端的其中1个本地IP地址相同)，可认为所述IP数据包为正常数据业务流量。
其中，若IP路由信息表中未查找到与接收到的IP数据包的目的IP地址匹配的记录(即所述IP数据包的目的IP地址与所述移动终端的任意1个本地IP地址均不相同)，可认为所述IP数据包可能为非正常数据业务流量。
S306、移动终端的Modem确定上述IP数据包的传输协议类型。
若确定上述IP数据包的传输协议类型为ICMP，则执行步骤S307。
若确定上述IP数据包的传输协议类型为UDP，则执行步骤S308。
若确定上述IP数据包的传输协议类型为TCP，则执行步骤S309。
S307、移动终端的Modem向网络发送响应所述IP数据包的answer数据包。
S308、移动终端的Modem丢弃所述IP数据包。
S309、移动终端的Modem向网络发送响应所述IP数据包的复位(RST)数 据包。
可选的，在本发明的一些可能的实施方式中，若确定所述移动终端的数据业务未处于联网状态，所述调制解调器在根据所述IP数据包的传输协议类型对所述IP数据包进行处理之后，控制所述移动终端进入待机状态。其中，在所述移动终端的数据业务未处于联网状态的情况下，那么移动终端被垃圾包(所述IP数据包)触发进入链接(CONNECTED)状态，则无需等待网络超时即可控制移动终端进入待机(IDLE)状态，这样也有利于进一步降低移动终端待机耗电量。
可以看出，本实施例中的技术方案中，当移动终端的Modem在接收来自网络的网际互联协议IP数据包，移动终端的Modem确定所述移动终端的数据业务的联网状态，若确定移动终端的数据业务未处于联网状态，由Modem根据所述IP数据包的传输协议类型对所述IP数据包进行处理，并且由于在确定所述移动终端的数据业务未处于联网状态的情况下，所述Modem不向所述移动终端的应用处理器转发所述IP数据包，因此对于应用处理器而言无效的一些IP数据包可以被Modem阻断，可使得在数据业务断开后移动终端的应用处理器被无故唤醒的可能性极大降低，有利于极大减少应用处理器对无效IP数据包的处理，进而有利于降低移动终端的待机功耗，进而提升用户产品体验。
