Description

传输数据的方法、接入网设备和终端设备 技术领域
本发明涉及通信领域，并且更具体地，涉及一种传输数据的方法、接入网设备和终端设备。
背景技术
在无线通信系统中，终端设备有两种基本的模式：一种是空闲模式(也就是通常所说的待机状态)，另一种是连接模式。当终端设备处于连接模式时，该终端设备与演进的通用陆地无线接入网络(Terrestrial Radio Access Network，简称为“UTRAN”)之间有无线资源控制(Radio Resource Control，简称为“RRC”)连接。
在终端设备处于空闲模式的情况下，如果终端设备需要接收或者发送数据，那么终端设备需要从空闲模式转换为连接模式然后再进行数据的传输，当数据传输结束后终端设备可以再从连接模式转换为空闲模式。但是终端设备在空闲模式与连接模式之间的频繁转换会造成终端设备的信令开销增加，最终导致终端设备的功耗增大。
发明内容
本发明提出一种传输数据的方法、接入网设备和终端设备，能够使得终端设备在与数据包匹配的状态来传输数据包。
第一方面，提供一种传输数据的方法，包括：接入网设备接收核心网设备发送的第一数据包；所述接入网设备确定终端设备接收所述第一数据包需要处于的状态，所述终端设备接收所述第一数据包需要处于状态为至少两种状态中的任意一种，所述至少两种状态为所述终端设备与网络侧设备处于数据传输时的不同状态；所述接入网设备向所述终端设备发送所述第一数据包。
通过接入网设备来确定终端设备接收第一数据包需要处于的状态，能够使得终端设备在与第一数据包匹配的状态来接收第一数据包。
具体来说，如果上述第一数据包比较小，那么接入网设备可以确定终端设备在第一状态(该第一状态可以是非激活态)接收该第一数据包，如果第 一数据包较大，那么接入网设备可以确定终端设备在第二状态(该第二状态可以是激活态)接收该第一数据包。而现有技术中并没有考虑到终端设备要根据数据包的不同采用相应的状态来接收数据包，因此，本发明实施例的传输数据的方法能够选择在与数据包匹配的状态来接收数据包，能够更好地进行数据的传输。
结合第一方面，在第一方面的第一种实现方式中，所述至少两种状态包括第一状态和第二状态，其中，在所述第一状态下，所述终端设备和所述接入网设备保持连接，所述终端设备和所述接入网设备保存所述终端设备的上下文信息，当所述终端设备在所述接入网设备所属的接入网设备集合中的所有接入网设备的覆盖范围内的移动时，所述终端设备执行小区重选过程，所述终端设备不进行接入网设备的切换；在所述第二状态下，当所述终端设备在所述接入网设备所属的接入网设备集合中的所有接入网设备的覆盖范围内的移动时，所述接入网设备控制所述终端设备进行接入网设备的切换。

具体实施方式
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做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。
本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)或全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统，以及未来可能出现的通讯系统等。
在本发明实施例中，终端设备可以称之为用户设备(User Equipment，简称为“UE”)、终端设备、移动台(Mobile Station，简称为“MS”)、移动终端(Mobile Terminal)或未来5G网络中的终端设备等，该终端设备可以经无线接入网(Radio Access Network，简称为“RAN”)与一个或多个核心网进行通信，例如，终端可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等，例如，终端还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。
本发明实施例中的接入网设备能够与移动设备进行通信，接入网设备可 以是全球移动通讯(Global System of Mobile communication，简称为“GSM”)或码分多址(Code Division Multiple Access，简称为“CDMA”)中的基站(Base Transceiver Station，简称为“BTS”)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)中的基站(NodeB，简称为“NB”)，还可以是长期演进(Long Term Evolution，简称为“LTE”)中的演进型基站(Evolutional Node B，简称为“eNB”或“eNodeB”)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的接入网设备。
核心网设备可以是移动性管理实体(Mobility Management Entity，简称为“MME”)，还可以是服务网关(Serving Gateway，简称为“S-GW”)或分组数据网关(PDN Gateway，简称为“P-GW”)，本发明并不限定。
为了更好地理解本发明实施例，下面先对终端设备的空闲模式和连接模式进行描述。
空闲模式只有一个空闲(Idle)状态。在Idle状态下，UE的所有连接在接入层都是关闭的。UTRAN中没有为处于空闲模式下的UE建立上下文，如果要寻址一个特定的UE，只能在一个小区内向所有UE或向监听同一寻呼时段的多个UE发送寻呼消息。
连接模式共有四种状态：CELL-PCH(小区寻呼信道状态)、URA-PCH(UTRAN注册区域寻呼信道状态)、CELL-FACH(小区前向接入信道状态)和CELL-DCH(小区专用信道状态)。其中，CELL-DCH为高层信令连接的连接模式，也可以称为“激活状态”。
图1是本发明实施例的传输数据的方法的示意性流程图。图1所示的方法包括：
110、接入网设备接收核心网设备发送的第一数据包。
上述第一数据包可以是核心设备发送给终端设备的下行数据中的数据包。
120、接入网设备确定终端设备接收第一数据包需要处于的状态，终端设备接收第一数据包需要处于状态为至少两种状态中的任意一种，该至少两种状态为终端设备与网络侧设备处于数据传输时的不同状态。
应理解，上述至少两种状态可以是终端设备处于连接模式下与网络侧进行数据的传输时的两种状态，具体地，上述至少两种状态可以是终端设备与网络侧设备处于无线资源控制(Radio Resource Control，RRC)连接时的不 同状态。
可选地，上述至少两种状态包括第一状态和第二状态，第一状态和第二状态是终端设备处于连接模式下的两种不同的状态，其中，在第一状态下，终端设备和接入网设备保持连接，终端设备和接入网设备保存终端设备的上下文信息，终端设备在接入网设备所属的接入网设备集合中的所有接入网设备的覆盖范围内的移动时，执行小区重选过程，不进行接入网设备的切换；而在第二状态下，当终端设备在接入网设备所属的接入网设备集合中的所有接入网设备的覆盖范围内的移动时，接入网设备控制终端设备进行接入网设备的切换。
也就是说，在第一状态下，终端设备不进行接入网设备的切换，接入网设备集合中的所有接入网设备以及核心网设备不能够感知到该终端设备的移动，终端设备的移动对于网络侧设备是不可知的。
在第二状态下，当终端设备从一个小区移动到另一个小区时，由该终端设备所属的接入网设备控制终端设备进行接入网设备的切换，在这种情况下，接入网设备是能够感知到终端设备在不同接入网设备的覆盖范围之间的移动的。
具体地，上述第一状态可以是非激活态，第二状态可以为激活态，本发明实施例对第一状态和第二状态的具体名称不做限定。
130、接入网设备向终端设备发送第一数据包。
本发明实施例中，通过接入网设备来确定终端设备接收第一数据包需要处于的状态，能够使得终端设备在与第一数据包匹配的状态来接收第一数据包。
具体来说，如果上述第一数据包比较小(是指数据包的大小比较小)，那么接入网设备可以确定终端设备以第一状态(该第一状态可以是非激活态)接收第一数据包，如果第一数据包较大，那么接入网设备可以确定终端设备以第二状态(该第二状态可以是激活态)接收第一数据包。而现有技术中并没有考虑到要根据数据包的不同而采用不同的状态来接收数据包，因此，本发明实施例的传输数据的方法能够确定终端设备在何种状态接收数据包，能够更好地进行数据的传输。
可选地，作为一个实施例，接入网设备确定终端设备接收数据包需要处于的状态，包括：接入网设备获取核心网设备的辅助信息；接入网设备根据 核心网设备的辅助信息确定终端设备接收数据包所需要的状态。
上述核心网设备的辅助信息可以包括在终端设备与网络侧设备建立的承载或者数据流的相关信息，具体地，上述核心网设备的辅助信息可以包括承载的信息和数据流的信息。
可选地，作为一个实施例，接入网设备确定终端设备接收第一数据包需要处于的状态，包括：接入网设备从核心网设备获取第一数据包对应的承载的信息或者数据流的信息；接入网设备根据第一数据包对应的承载的信息或者数据流的信息确定终端设备接收第一数据包需要处于的状态。
上述第一数据包对应的承载的信息或者数据流的信息可以是在核心网设备在建立承载或者数据流时配置的信息。
可选地，作为一个实施例，接入网设备确定终端设备接收第一数据包需要处于的状态，包括：接入网设备获取承载或者数据流的第一指示信息，该第一指示信息用于指示终端设备接收该承载或者数据流对应的数据包需要处于的状态；接入网设备根据该第一指示信息确定终端设备接收第一数据包需要处于的状态。
应理解，上述第一指示信息可以携带在承载或者数据流的配置信息中的某个空闲字段中。另外，上述第一指示信息可以指示终端设备接收承载或者数据流对应的多个数据包需要处于的状态，这样终端设备可以根据该第一指示信息确定接收当前数据包时终端设备需要处于的状态。
具体来说，这里可以采用承载或者数据流的配置信息来直接指示终端设备接收数据包时需要处于的状态，也就是说核心网设备在配置承载或者数据流的时候就已经确定了终端设备接收上述承载或者数据流对应的数据包时需要处于什么状态，并将相关的指示信息携带在配置信息中，这样接入网设备就可以直接根据该配置信息去判断终端设备接收数据包时需要处于的状态了。应理解，这里的配置信息可以是在建立承载或者数据流时，核心网设备为该承载或者数据流配置的信息，这里的配置信息可以包括承载或者数据流本身的属性信息，例如，数据包大小等。
可选地，作为一个实施例，接入网设备确定终端设备接收所述第一数据包需要处于的状态，包括：接入网设备从核心网设备获取第一数据包对应的承载或者数据流的属性信息；接入网设备根据承载或者数据流的属性信息判断终端设备接收第一数据包需要处于的状态。
应理解，接入网设备既可以根据承载或者数据流的配置信息中包含的第一指示信息来直接确定终端设备接收第一数据包需要处于的状态，也可以根据承载或者数据流的本身的一些属性信息进行判断从而确定终端设备接收第一数据包需要处于的状态。上述属性信息可以包含承载或者数据流的服务质量(Quality of Service，QoS)信息。
上述承载或者数据流的属性信息可以具体包括承载或者数据流的数据时延信息，承载或者数据流对应的数据包的大小，承载或者数据流对应的数据包的发送时间间隔等。
具体地，终端设备在根据承载或者数据流的属性信息判断终端设备接收第一数据包需要处于的状态时包括：接入网设备根据数据时延、数据包大小、数据包发送时间间隔中的至少一种判断终端设备接收第一数据包需要处于的状态。
接入网设备可以根据数据时延、数据包大小以及数据包发送时间间隔中的一种或者多种来判断终端设备接收第一数据包需要处于的状态。
例如，当承载或者数据流的数据时延较大时，接入网设备可以判断终端设备接收第一数据包需要处于的状态为非激活态，而当承载或者数据流的数据时延较小时，接入网设备可以判断终端设备接收第一数据包需要处于的状态为激活态。也就是说，当数据时延超过预设阈值时，接入网设备判断终端设备接收第一数据包需要处于非激活态，当数据时延小于预设阈值时，接入网设备判断终端设备接收第一数据包需要处于激活态。
当第一数据包较小时，接入网设备可以判断终端设备接收第一数据包需要处于的状态为非激活态，而第一数据包较大时，接入网设备可以判断终端设备接收第一数据包需要处于的状态为激活态。具体地，当第一数据包的大小小于预设阈值时，接入网设备判断终端设备接收第一数据包需要处于非激活态，当第一数据包的大小大于预设阈值时，接入网设备判断终端设备接收第一数据包需要处于激活态。
当第一数据包的发送时间间隔或者到达时间间隔较长时，接入网设备可以判断终端设备接收第一数据包需要处于的状态为非激活态，而第一数据包的发送时间间隔或者到达时间间隔较小时，接入网设备可以判断终端设备接收第一数据包需要处于的状态为激活态。具体地，当第一数据包的发送时间间隔超过预设阈值时，接入网设备判断终端设备接收第一数据包需要处于非 激活态，当第一数据包的发送时间间隔小于预设阈值时，接入网设备判断终端设备接收第一数据包需要处于激活态。
应理解，接入网设备还可以根据数据时延、数据包大小以及数据包发送时间间隔中的多种来共同确定终端设备接收第一数据包需要处于的状态。
可选地，作为一个实施例，接入网设备确定终端设备接收第一数据包需要处于的状态，包括：接入网设备从核心网设备获取第二指示信息，该第二指示信息用于指示终端设备接收第一数据包需要处于的状态；接入网设备根据该第二指示信息确定终端设备接收第一数据包需要处于的状态。
上述第二指示信息可以是核心网设备在向接入网设备发送第一数据包之前发送的信息。
核心网设备可以在有数据发送给终端设备之前向接入网设备发送上述第二指示信息，这样接入网设备就可以直接根据该第二指示信息确定接收第一数据包需要处于的状态，接下来，核心网设备向接入网设备发送第一数据包，接入网设备在接收到第一数据包后，再将第一数据包发送给终端设备。
另外，核心网设备除了向接入网设备发送一个单独的指示信息(第二指示信息)来指示数据包传输时终端设备需要处于的状态外，还可以将类似的指示信息携带在核心网设备发送给接入网设备的数据包中。
可选地，作为一个实施例，上述第一数据包携带有第一数据包的第三指示信息，该第三指示信息用于指示终端设备接收第一数据包需要处于的状态，接下来，接入网设备从第一数据包获取第一数据包的第三指示信息；终端设备根据该第三指示信息，确定终端设备接收第一数据包需要处于的状态。
应理解，上述第一数据包也可以携带其它数据包的第三指示信息，这样，接入网设备或者终端设备可以根据第一数据包中携带的其它数据包的第三指示信息确定终端设备接收其它数据包时需要处于的状态。
可选地，上述第三指示信息可以携带在第一数据包的用户平面隧道协议(GPRS Tunnelling Protocol for the Userplane，GTP-U)头字段中。
可选地，作为一个实施例，接入网设备确定终端设备接收第一数据包需要处于的状态，包括：接入网设备根据第二数据包携带的第一数据包的第四指示信息，确定终端设备接收第一数据包需要处于的状态，其中，第一数据包的第四指示信息用于指示终端设备接收第一数据包需要处于的状态，第二 数据包是接入网设备在接收第一数据包之前接收的数据包。
也就是说，接入网设备在确定终端设备接收第一数据包需要处于的状态时，可以根据第一数据包本身携带的第一数据包的第三指示信息或者其它数据包携带的第一数据包的第四指示信息，来确定终端设备接收第一数据包需要处于的状态。
可选地，上述第二数据包可以携带包括第一数据包在内的多个数据包的第四指示信息，具体可以包含以下两种情况：
(1)第二数据包携带从第二数据包开始的N个数据包的第四指示信息，该N个数据包包含第二数据包和第一数据包，N为大于1的整数。
(2)第二数据包携带有从第二数据包开始到序列号为N的多个数据包的第四指示信息，该多个数据包包含第二数据包和第一数据包，N为大于1的整数。
也就是说，对于第二数据包来说，不仅可以携带第二数据包本身的第四指示信息，也可以携带其它数据包的第四指示信息。
可选地，接入网设备可以向终端设备发送上述第二数据包，以便于终端设备根据上述第二数据包携带的N个数据包的第四指示信息确定接收第一数据包需要处于的状态，或者，以便于终端设备根据上述第二数据包携带的多个数据包的第四指示信息确定接收第一数据包需要处于的状态。
具体地，终端设备在接收到接入网设备的第二数据包之后，可以从第二数据包中携带的N个数据包或者多个数据包的第四指示信息中获取第一数据包的第四指示信息，这样就可以根据第一数据包的第四指示信息确定终端设备接收第一数据包需要处于的状态。
应理解，接入网设备可以在向终端设备发送第一数据包之前向终端设备发送第二数据包。
可选地，在第二数据包中，多个数据包的第四指示信息可以携带在第二数据包的GTP-U头字段中。
具体地，如表1所示，可以在第一数据包的GTP-U头字段中添加一个数据状态(Data State)字段，在数据状态字段携带第一数据包的第三指示信息。这样，接入网设备在接收到该数据包之后，通过解析第一数据包就可以获取第一数据包的第三指示信息，然后再根据第一数据包的第三指示信息就可以确定终端设备接收第一数据包需要处于的状态。应理解，在第一数据包 中，也可以携带其它数据包中的第三指示信息。
此外，也可以在第二数据包的GTP-U头字段中添加一个数据状态(Data State)字段，如果第二数据包的序号为1，那么第二数据包的数据状态字段可以携带从序号1到序号N(N为大于1的整数)的N个数据包的第四指示信息，其中，这N个数据包包括第二数据包本身以及第一数据包。如果第二数据包的序号为3，那么第二数据包的数据状态字段可以携带从序号3到序号N(N为大于3的整数)的多个数据包的数据指示信息，其中，该多个数据包包括第二数据包本身以及上述第一数据包。
应理解，第一数据包中携带的第一数据包的第三指示信息与第二数据包中携带的第一数据包的第四指示信息的作用是相同的，它们都可以用于指示终端设备接收第一数据包需要处于的状态，只是第一数据包的第三指示信息携带在第一数据包中，而第一数据包的第四指示信息携带在第二数据包中。

可选地，接入网设备在向终端设备发送数据包之前，接入网设备向终端设备发送第五指示信息，该第五指示信息用于指示终端设备接收第一数据包 需要处于的状态。
具体来说，假设终端设备当前处于第一状态，并且接入网设备确定终端设备接收第一数据包需要处于的状态为第一状态，那么接入网设备可以向终端设备发送第五指示信息，以通知终端设备要以第一状态接收第一数据包，或者，终端设备也可以不向终端设备发送第五指示信息，而是直接向终端设备发送第一数据包。
而如果终端设备当前处于第二状态，那么接入网设备可以向终端设备发送该第五指示信息，终端设备在接收到该第五指示信息之后与接入网设备进行一系列的交互过程，从第二状态切换为第一状态，然后在第一状态接收接入网设备发送的第一数据包。
应理解，上述第五指示信息可以是寻呼消息，也就是说接入网设备可以通过向终端设备发送寻呼消息来通知终端设备接收数据包需要处于的状态。
上文结合图1从接入网设备的角度对本发明实施例的传输数据的方法进行了详细的介绍，下面结合图2从终端设备的角度对本发明实施例的传输数据的方法进行了详细的描述。
图2是本发明实施例的传输数据的方法的示意性流程图。图2的方法包括：
210、终端设备确定向接入网设备发送数据包时需要处于的状态，接入网设备发送数据包时需要处于的状态为至少两种状态中的任意一种，该至少两种状态为终端设备与网络侧设备处于数据传输时的不同状态。
上述至少两种状态可以是终端设备处于连接模式下与网络侧进行数据的传输时的两种状态，具体地，上述至少两种状态可以是终端设备与网络侧设备处于RRC连接时的不同状态。
可选地，上述至少两种状态包括第一状态和第二状态，第一状态和第二状态是终端设备处于连接模式下的两种不同的状态，其中，在第一状态下，终端设备和接入网设备保持连接，终端设备和接入网设备保存终端设备的上下文信息，终端设备在接入网设备所属的接入网设备集合中的所有接入网设备的覆盖范围内的移动时，执行小区重选过程，不进行接入网设备的切换；而在第二状态下，当终端设备在接入网设备所属的接入网设备集合中的所有接入网设备的覆盖范围内的移动时，接入网设备控制终端设备进行接入网设备的切换。
也就是说，在第一状态下，终端设备不进行接入网设备的切换，接入网设备集合中的所有接入网设备以及核心网设备不能够感知到该终端设备的移动，终端设备的移动对于网络侧设备是不可知的。在第二状态下，当终端设备从一个小区移动到另一个小区时，由该终端设备所属的接入网设备控制终端设备进行接入网设备的切换，在这种情况下，接入网设备是能够感知到终端设备在不同接入网设备的覆盖范围之间的移动的。
上述第一状态可以是非激活态，第二状态可以为激活态。
220、终端设备在送数据包需要处于的状态向接入网设备发送数据包。
具体来说，假设终端设备当前的状态为第一状态，而终端设备经过步骤210确定终端设备发送上行数据需要处于的状态为第二状态，那么终端设备需要从当前的第一状态转换为第二状态，然后以第二状态发送数据包，而如果终端设备经过步骤210确定终端设备发送上行数据需要处于的状态为第一状态，那么终端设备就不必进行状态的转换，终端设备在第一状态发送数据包。
本发明实施例中，终端设备在发送数据包之前先确定发送该数据包所需处于的状态，能够使得终端设备在与数据包匹配的状态发送该数据包。
具体来说，如果上述数据包比较小，那么终端设备可以确定以第一状态(该第一状态可以是非激活态)发送该数据包，如果数据包较大，那么终端设备可以确定以第二状态(该第二状态可以是激活态)发送该数据包。而现有技术中并没有考虑到要根据数据包的不同采用相应的状态来发送数据包，因此，本发明实施例的传输数据的方法能够选择与数据包匹配的状态来发送数据包，能够更好地进行数据的传输。
可选地，作为一个实施例，终端设备确定发送数据包需要处于的状态，包括：终端设备根据预先获取的与数据包对应的承载的信息或者数据流的信息确定发送数据包需要处于的状态。
上述与数据包对应的承载的信息或者数据流的信息可以是终端设备之前从接入网设备获取的或者是从签约信息获得的，另外，上述与数据包对应的承载的信息或者数据流的信息也可以是终端设备从核心网设备获取的。当终端设备需要发送上行数据时就可以根据这些承载的信息或者数据流的信息确定待发送的上行数据需要处于的状态。
可选地，作为一个实施例，终端设备根据预先获取的与数据包对应的承 载信息或者数据流信息确定发送数据包需要处于的状态，包括：终端设备根据承载或者数据流的配置信息中的第一指示信息，确定发送数据包需要处于的状态，其中，上述第一指示信息用于指示承载或者数据流对应的数据包传输时终端设备需要处于的状态。
可选地，作为一个实施例，终端设备根据预先配置的承载的信息或者数据流的信息确定发送数据包需要处于的状态，包括：终端设备根据承载或者数据流的属性信息，判断发送数据包需要处于的状态。
上述属性信息可以包含承载或者数据流的服务质量(Quality of Service，QoS)信息。上述终端设备既可以根据承载或者数据流的配置信息中包含的信息来直接确定终端设备接收数据包需要处于的状态，也可以根据承载或者数据包的本身的一些属性信息进行判断从而确定终端设备发送数据包时需要处于的状态。
上述承载或者数据流的属性信息可以具体包括承载或者数据流的数据时延信息，承载或者数据流对应的数据包的大小，承载或者数据流对应的数据包的发送时间间隔等。
终端设备可以直接根据预先获取的第一指示信息确定终端设备发送数据包需要处于的状态，也可以通过数据包对应的承载或者数据流的本身的属性信息去判断终端设备发送数据包时需要处于的状态。
可选地，作为一个实施例，终端设备根据承载或者数据流的属性信息，判断发送数据包需要处于的状态，包括：终端设备根据数据时延、数据包大小、数据包发送时间间隔中的至少一种判断终端设备发送数据包需要处于的状态。
具体地，当承载或者数据流的数据时延超过预设阈值时，终端设备可以判断发送数据包需要处于的状态为非激活态，而当承载或者数据流的数据时延小于预设阈值时，终端设备可以判断发送数据包需要处于的状态为激活态。
当数据包的大小小于预设阈值时，终端设备可以判断发送数据包需要处于的状态为非激活态，而数据包大小大于预设阈值时，终端设备可以判断发送数据包需要处于的状态为激活态。
当数据包的发送时间间隔或者到达时间间隔超过预设阈值时，终端设备可以判断发送数据包需要处于的状态为非激活态，而数据包的发送时间间隔 或者到达时间间隔小于预设阈值时，终端设备可以判断发送数据包需要处于的状态为激活态。
应理解，终端设备还可以根据数据时延、数据包大小以及数据包发送时间间隔中的多种来共同确定发送数据包需要处于的状态。
可选地，作为一个实施例，终端设备当前处于第一状态，终端设备以发送上行数据包需要处于的状态向接入网设备发送数据包，包括：如果终端设备确定发送数据包需要处于的状态为第二状态，终端设备从第一状态转换成第二状态；终端设备以第二状态向接入网设备发送数据包。
例如，终端设备在发送上行数据之前，经过判断确定该发送该上行数据需要处于的状态为激活态，而终端设备当前处于非激活态，那么终端设备需要先从非激活态转换成激活态，接下来，在激活态状下向接入网设备发送上行数据。在发送上行数据之后，终端设备可以继续维持激活态，也可以从激活态转换为非激活态。
上文结合图1和图2详细的描述了本发明实施例的传输数据的方法，下面结合图3-6，详细的描述本发明实施例的接入网设备和终端设备。应理解，图3-6中的接入网设备和终端设备能够分别执行本发明实施例的传输数据的方法中由接入网设备和终端设备执行的各个步骤，为了避免重复，此处不再详述。
