目前,在数据传输过程中,在移动终端与无线接入网设备之间建立DRB之前,通常还需要经历以下过程:移动终端与该无线接入网设备之间建立无线资源控制(Radio Resource Control,以下简称RRC)连接,当RRC连接建立成功后,该无线接入网设备向核心网设备发送建立连接请求,该核心网设备接收到该建立连接请求后,向该无线接入网设备发送建立连接响应,该无线接入网设备接收到该建立连接响应后,通过S1接口与该核心网设备之间建立连接。之后,该无线接入网设备通过初始安全性激活进程发起安全激活过程(包括加密和完整性保护),当安全激活过程启动后,无线接入网设备再发起DRB建立过程。
由此可见,上述提供的数据传输方法中,由于需要经过多次信令交互后,移动终端和无线接入网设备之间才能建立DRB,并基于该DRB来进行数据传输,因此,导致数据传输的时延较大。

图2A是根据一示例性实施例示出的一种数据传输方法流程图,本申请实施例以无线接入网设备和移动终端交互的方式实现该数据传输方法为例进行说明,该数据传输方法可以包括如下几个步骤:
步骤201:无线接入网设备确定预置数据承载的配置信息,该预置数据承载用于传输数据,该配置信息包括通过该预置数据承载在无线接口传输的数据的数据传输方式。
本申请实施例中引入预置数据承载的机制,即基于本申请实施例所提供的数据传输方法,用于传输数据的数据承载可以由两部分组成,一部分是指传统的通过专用信令过程建立的DRB,另一部分则为本申请实施例所涉及的预置数据承载。
其中,该预置数据承载可以属于每个小区或基站,即小区或基站下的每个移动终端均可以使用该小区或基站配置的预置数据承载。因此,在一种可能的实现方式中,该预置数据承载也可以称之为小区数据承载。另外,在第五代(Fifth Generation,以下简称5G)移动通信中,由于网络可以分为网络切片,因此,该该预置数据承载也可以属于各个网络切片,即在一种可能的实现方式中,在5G移动通信中,可以通过网络切片,建立预置数据承载。
在一种可能的实现方式中,上述无线接入网设备确定预置数据承载的配置信息的实现 过程可以包括:请参考图2B,在与核心网设备建立接口连接时,无线接入网设备向核心网设备发送接口建立请求,该核心网设备接收到接口建立请求后,返回接口建立响应,该接口建立响应中携带承载建立指示,该承载建立指示中包括服务质量(Quality of Service,以下简称QoS),无线接入网设备基于该QoS,生成预置数据承载的配置信息。其中,承载建立指示中可以指示建立多个预置承载,无线接入网设备可以据此生成一个或者多个预置数据承载的配置信息。
需要说明的是,上述无线接入网设备与核心网设备建立连接的接口是指无线接入网设备与核心网设备之间的公共接口,而不是针对某个移动终端建立的接口。
例如,在长期演进(Long Term Evolution,以下简称LTE)网络中,在建立S1接口连接过程中,无线接入网设备向核心网设备发送S1接口建立请求,该核心网设备接收到该S1接口建立请求后,向该无线接入网设备发送携带上述承载建立指示的S1接口建立响应,该无线接入网设备接收到该S1接口建立响应后,从该S1接口建立响应中获取承载建立指示,基于该承载建立指示中包括的QoS,生成预置数据承载的配置信息。
其中,无线接入网设备基于QoS生成预置数据承载的配置信息的具体实现过程可以参见相关技术,本申请实施例对此不做限定。
当然,需要说明的是,上述确定预置数据承载的配置信息的实现仅是示例性的,在另一种可能的实现方式中,该QoS也可以是由该无线接入网设备在与核心网设备之间完成接口建立后,向核心网设备发送QoS获取请求,以使该核心网设备将QoS发送给该无线接入网设备,之后,该无线接入网设备基于该QoS生成预置数据承载的配置信息。
其中,该预置数据承载的配置信息包括预置数据承载标识、逻辑信道信息、无线链路控制(Radio Link Control,以下简称RLC)配置信息和包数据汇聚协议(Packet Data Convergence Protocol,以下简称PDCP)配置信息中的至少一种。
其中,该预置数据承载标识用于唯一标识一个预置数据承载,在一种可能的实现方式中,该预置数据承载标识与DRB标识统一编号,例如,若将某DRB标识编号为“1”,则预置数据承载标识可以编号为“2”,之后当再建立有DRB,则可以继续按照该顺序进行后续编号。
需要说明的是,该预设数据承载的配置信息除了包括上述信息外,还可以包括其它可选信息。
具体地,该预置数据承载的配置信息包括使用条件信息和/或第一映射关系,该使用条件信息用于表示能够使用该预置数据承载的移动终端需要具备的条件,该第一映射关系为数据类型与支持该数据类型的数据承载之间的映射关系。
在一种可能的实现方式中,该使用条件信息和/或第一映射关系可以由核心网设备指定,也即是,该使用条件信息和/或第一映射关系可以是由核心网设备在上述承载建立指示中携带。进一步地,在该种情况下,该第一映射关系可以包含在非接入层协议数据单元(Non-Access-Stratum Protocol Data Unit,以下简称NAS PDU)中,即该NAS PDU包含数据类型与支持该数据类型的数据承载之间的映射关系,根据该第一映射关系和传输的数据包中包括的网络协议(Internet Protocol,以下简称IP)五元组等信息,移动终端可以确定数据应该在哪个数据承载上进行传输。
其中,上述IP五元组包括源IP地址、目标IP地址、源端口号、目标端口号以及传输 协议。该源IP地址是指发送端的IP地址,目标IP地址是指接收端的IP地址,源端口号是指发送端的端口号,目标端口号是指接收端的端口号,传输协议是指用于传输数据的协议。
在另一种可能的实现方式中,该使用条件信息和/或第一映射关系也可以是由该无线接入网设备本身指定,也即是,该使用条件信息和/或第一映射关系也可以由该无线接入网设备基于QoS自动生成。
当该配置信息包括使用条件信息时,说明无线接入网设备限制了可以使用该预置数据承载的条件,该条件信息具体可以包括如下(1)-(3)实现方式中的任一种:
该条件信息可以包括特定业务标识,该特定业务标识用于唯一标识一种特定业务。在该种情况下,意味着只有签约了该特定业务的移动终端才具备使用预置数据承载的条件,或者,当该移动终端发起该特定业务时,即可具备使用预置数据承载的条件。
该条件信息可以包括特定类型标识,该特定类型标识可以用于唯一标识一种类型的移动终端,在该种情况下,意味着只有该特定类型的移动终端才可以使用该预置数据承载。
该条件信息可以包括特定业务标识和特定类型标识,在该种情况下,意味着只有特定类型的移动终端签约了该特定业务或当发起该特定业务时,该移动终端才具有使用该预置数据承载的条件。
步骤202:无线接入网设备在与移动终端完成建立无线资源控制RRC连接之前,将该预置数据承载的配置信息发送至该移动终端,该预置数据承载的配置信息用于该移动终端通过该预置数据承载传输数据。
无线接入网设备确定预置数据承载的配置信息后,在与移动终端完成建立无线资源控制RRC连接之前,就可以将该配置信息发送给移动终端。其中,无线接入网设备将该预置数据承载的配置信息发送至该移动终端的实现方式可以包括:
广播系统信息,该系统信息包括该预置数据承载的配置信息。请参考图2C,在该种实现方式中,无线接入网设备通过广播系统信息的方式,将该配置信息发送给移动终端。
步骤203:移动终端在与无线接入网设备完成建立无线资源控制RRC连接之前,接收该无线接入网设备发送的预置数据承载的配置信息。
具体地,接收该无线接入网设备广播的系统信息,该系统信息包括该预置数据承载的配置信息。
也即是,当无线接入网设备以广播系统信息的方式将预置数据承载的配置信息发送给移动终端时,相应地,移动终端接收该无线接入网设备广播的系统信息,并从该系统信息中获取预置数据承载的配置信息。
移动终端通过上述方式接收到无线接入网设备发送的预置数据承载的配置信息后,存储将该预置数据承载的配置信息。
步骤204:移动终端在与该无线接入网设备完成建立RRC连接之后,基于该预置数据承载的配置信息通过该预置数据承载传输数据。
请参考图2C,当与该无线接入网设备完成建立RRC连接之后,就可以认为预置数据承载已经建立完成,即该预置数据承载是可用的,在该种情况下,移动终端可以基于该预置数据承载的配置信息通过该预置数据承载传输数据。
在基于该预置数据承载的配置信息通过该预置数据承载传输数据的过程中,该配置信息中一些配置信息的参数可以使用指定协议规定的默认值,对于该类默认值,可以不需要 无线接入网设备发送给该移动终端,如此,减少了广播信令的开销。而在实际应用中,可能无线接入网设备需要规定一些配置信息的参数,在该种情况下,无线接入网设备可以广播需要规定的配置信息的参数。也就是说,如果无线接入网设备广播了配置信息的参数,则移动终端使用所广播的参数,如果无线接入网设备没有广播,则移动终端使用指定协议规定的默认值。
其中,该指定协议可以由用户根据实际需求自定义设置,也可以由移动终端默认设置,本申请实施例对此不做限定。
另外,需要说明的是,在本申请实施例中,仅是以移动终端在与该无线接入网设备完成建立RRC连接之后,基于该预置数据承载的配置信息通过该预置数据承载传输数据为例进行说明,在另一实施例中,本申请实施例所提供的数据传输方法也可以适用于不建立RRC连接的场景,比如,对于小包数据传输,不建立RRC连接,而是当移动终端通过竞争的方式获取到传输数据资源后,移动终端也可以使用该预置数据承载进行数据传输。
此外,还需要说明的是,如前文所示,该配置信息中可能还包括上述可选的信息,当该配置信息中包括上述可选的配置信息时,对于移动终端来说,在基于该预置数据承载的配置信息通过该预置数据承载传输数据之前,需要根据该可选的配置信息,执行对应的操作,具体包括如下几种可能的实现方式:
第一种可能的实现方式:当该预置数据承载的配置信息包括使用条件信息时,判断是否具备该使用条件信息所指示的条件,该使用条件信息用于表示能够使用该预置数据承载的移动终端需要具备的条件,当具备该使用条件信息所指示的条件时,执行该基于该预置数据承载的配置信息通过该预置数据承载传输数据的步骤。
如上文所述,当该配置信息中包括使用条件信息时,说明无线接入网设备限制了可以使用预置数据承载的条件,因此,移动终端需要判断自身是否具备该条件,只有当具备该条件时,该移动终端才能通过该预置数据承载传输数据。
例如,若该使用条件信息包括特定类型标识,且该特定类型标识为UE_1,如果该移动终端的类型标识为UE_1,则说明该移动终端具备该条件信息所指示的条件,在该种情况下,该移动终端可以通过该预置数据承载传输数据。但是,如果该移动终端的类型标识为UE_2,说明该移动终端不具备该条件信息所指示的条件,在该种情况下,该移动终端不能够通过该预置数据承载传输数据。
第二种可能的实现方式,当该预置数据承载的配置信息包括第一映射关系时,确定该数据所属的数据类型,该第一映射关系为数据类型与支持该数据类型的数据承载之间的映射关系,基于该第一映射关系,判断该数据所属的数据类型对应的数据承载是否为该预置数据承载,当该数据所属的数据类型对应的数据承载为该预置数据承载时,执行该基于该预置数据承载的配置信息通过该预置数据承载传输数据的步骤。
也即是,在传输数据之前,该移动终端确定待传输数据所属的数据类型,之后,该移动终端根据第一映射关系,判断待传输数据所属的数据类型对应的数据承载,如果该数据承载为预置数据承载,说明移动终端可以通过预置数据承载传输该待传输的数据,但是,如果该数据承载不是预置数据承载,则说明移动终端可以通过预置数据承载传输该待传输的数据。
步骤205:无线接入网设备在与该移动终端完成建立RRC连接之后,接收该移动终端 通过该预置数据承载发送的数据。
请参考图2C,移动终端在将数据传输给无线接入网设备后,相应地,该无线接入网设备开始接收数据,之后,该无线接入网设备将该数据发送到下一级节点,例如,将数据传输给服务网关。在一种可能的实现方式中,无线接入网设备在将数据传输给下一级节点之前,可能检测到发送条件不成熟,例如,可能无线接入网设备与下一级节点之间的数据传输路径还未建立,或者,当该数据为加密数据时,无线接入网设备还未接收到核心网设备发送的移动终端的解密密钥,在该种情况下,无线接入网设备缓存所接收的数据,并待发送条件成熟后,将所接收的数据发送给下一级节点,例如,当无线接入网设备与核心网设备通过上下文建立过程建立起数据传输路径,并且,通过接收核心网设备发送的移动终端上下文建立过程,确定解密密钥后,对缓存的数据进行解密处理,之后,将解密后的数据发送至下一级节点,从而实现数据传输。
需要说明的是,在基于预置数据承载传输数据后,无线接入网设备和移动终端可以执行后续流程,例如,请参考图2C,还可以继续执行安全激活、DRB建立等过程。
基于上述步骤实现了本申请实施例所提供的数据传输方法,然而,在实际应用中,在数据传输过程中,可能由于通信环境改变等因素,无线接入网设备可能需要修改配置信息,为此,在本申请实施例中,可选地,还提供了如下步骤206至步骤208。
步骤206:无线接入网设备在与该移动终端建立RRC连接后,向该移动终端发送携带指定配置信息的RRC信令,该RRC信令用于指示该移动终端修改该预置数据承载的配置信息为该指定配置信息。
也即是,在实际传输过程中,当无线接入网设备要修改预置数据承载的配置信息时,可以通过RRC信令来携带指定配置信息,以使移动终端在接收到接收RRC信令时,直接从该RRC信令中获取到该指定配置信息,即该指定配置信息由无线接入网设备确定。
步骤207:移动终端在与该无线接入网设备完成RRC连接建立之后,接收该无线接入网设备发送的携带指定配置信息的RRC信令。
步骤208:移动终端修改该预置数据承载的配置信息为该指定配置信息。
在本申请实施例中,确定可以用于传输数据的预设数据承载的配置信息,并在与移动终端完成建立无线资源控制RRC连接之前,将该配置信息发送给该移动终端,由于该配置信息包括通过该预置数据承载在无线接口传输的数据的数据传输方式,因此,移动终端接收到该配置信息后,可以基于该配置信息通过该预置数据承载传输数据,也即是,在完成建立RRC连接之后,移动终端即可通过该预置数据承载传输数据,避免需要经过多次信令交互后才能建立起数据承载,减小了数据传输时延。
图2A所示实施例中预置数据承载的配置信息包括的所有信息仅是示例性的,而在另一实施例中,该预置数据承载的配置信息除了可以包括上述图2A所提及的所有信息之外,还可以包括加密指示和/或容量指示信息。如图3所示,在该种情况下,移动终端在基于该预置数据承载的配置信息通过该预置数据承载传输数据之前,需要根据该加密指示和/或容量指示信息,对数据执行对应的操作。
步骤301:无线接入网设备确定预置数据承载的配置信息。
如前文所述,该预置数据承载的配置信息还可以包括加密指示和/或容量指示信息,具 体请参见如下(1)和(2)两种实现方式:
(1)该预置数据承载的配置信息包括加密指示,该加密指示用于指示该移动终端对需要传输的数据进行加密处理。
在数据传输过程中,为了数据传输的安全性,无线接入网设备可以根据实际需求,指示移动终端对待传输的数据进行加密处理,因此,该配置信息中可以携带加密指示。
另外,基于该种实现方式,当需要指示移动终端对待传输的数据进行加密处理时,还涉及到加密所使用的安全算法问题。因此,在一种可能的实现方式中,该预置数据承载的配置信息还包括安全算法标识,该安全算法标识用于指示该移动终端基于该安全算法标识对应的安全算法对需要传输的数据进行加密处理。
其中,该安全算法标识用于唯一标识一种安全算法。通常情况下,该安全算法标识对应的安全算法为较常用的,以使得绝大部分移动终端均支持该安全算法,在一种可能的实现方式中,若移动终端不支持该安全算法标识对应的安全算法,则该移动终端不能使用该预置数据承载。
当然,还需要说明的是,在本申请实施例中,仅是以该配置信息包括加密指示为例进行说明,在另一实施例中,该配置信息也可以不包括加密指示,例如,一般针对应用层会执行加密操作的业务,或者不需要加密的业务,或者核心网设备已经提供了安全保护的情况,可以不在该配置信息中携带加密指示。
(2)该预置数据承载的配置信息还包括容量指示信息,该容量指示信息用于表示允许该移动终端上传的最大上行数据量。
也即是,无线接入网设备考虑到自身的缓存能力,该无线接入网设备可以限制每个移动终端可以上传的最大上行数据量。
需要说明的是,该步骤301中确定预置数据承载的配置信息的实现方式与上述步骤201同理,在此不做赘述。
步骤302:无线接入网设备在与移动终端完成建立无线资源控制RRC连接之前,将该预置数据承载的配置信息发送至该移动终端。
该步骤与301与上述步骤201同理,在此不做赘述。
步骤303:移动终端在与无线接入网设备完成建立无线资源控制RRC连接之前,接收该无线接入网设备发送的预置数据承载的配置信息。
该步骤303与上述步骤203同理,在此不做赘述。
步骤304:移动终端在与该无线接入网设备完成建立RRC连接之后,基于该预置数据承载的配置信息通过该预置数据承载传输数据。
在本申请实施例中,由于该配置信息还可能包括加密指示和/或容量指示信息,因此,移动终端需要根据该加密指示和/或容量指示信息,判断是否具备基于该预置数据承载的配置信息通过该预置数据承载传输数据的条件,具体可以包括如下两种可能的实现方式:
第一种可能的实现方式:当该预置数据承载的配置信息包括加密指示时,对需要传输的数据进行加密处理。
请参考图3,当该预置数据承载的配置信息中包括加密指示时,说明无线接入网设备需要该移动终端对待传输的数据进行加密处理,在该种情况下,移动终端在RRC建立连接完成后,基于该RRC建立连接过程衍生出加密密钥,例如,在LTE网络中,移动终端可以基 于在RRC建立连接完成消息中携带的NAS消息的上行序列值,衍生出移动终端使用的加密密钥,之后,该移动终端即可以对该数据进行加密处理。
另外,当该预置数据承载的配置信息包括安全算法标识时,基于该安全算法标识对应的安全算法对需要传输的数据进行加密处理。
需要说明的是,在本申请实施例中,仅是以该配置信息包括该安全算法标识为例进行说明,在另一种可能的实现方式中,若该配置信息不包括安全算法标识,则移动终端可以使用上述指定协议默认规定的任一种安全算法。
第二种可能的实现方式:当该预置数据承载的配置信息包括容量指示信息时,判断预置数据承载上已经传输的数据的大小是否大于该容量指示信息所指示的最大上行数据量,当该预置数据承载上已经传输的数据的大小大于该容量指示信息所指示的最大上行数据量时,停止执行该基于该预置数据承载的配置信息通过该预置数据承载传输数据的步骤。
在一种可能的实现方式中,移动终端在基于该预置数据承载的配置信息通过该预置数据承载传输数据的过程中,也可以对所上传的数据量进行统计,当统计结果大于该最大上行数据量时,该移动终端停止基于该预置数据承载的配置信息通过该预置数据承载传输数据。
例如,若最大上行数据量为10M字节,如果在该预置数据承载上已经传输的数据的大小为11M字节,则移动终端不基于该预置数据承载的配置信息通过该预置数据承载传输数据。
另外,需要说明的是,上述对移动终端发送的上行数据量的限制仅是针对预置数据承载的,当无线接入网设备安全激活后,就可以不需要再对上行数据量进行限制。
步骤305:无线接入网设备在与该移动终端完成建立RRC连接之后,接收该移动终端通过该预置数据承载发送的数据。
该步骤305与上述步骤205同理,在此不做赘述。

在本申请实施例中,确定可以用于传输数据的预设数据承载的配置信息,并在与移动终端完成建立无线资源控制RRC连接之前,将该配置信息发送给该移动终端,由于该配置信息包括通过该预置数据承载在无线接口传输的数据的数据传输方式,因此,移动终端接收到该配置信息后,可以基于该配置信息通过该预置数据承载传输数据,也即是,在完成建立RRC连接之后,移动终端即可通过该预置数据承载传输数据,避免需要经过多次信令交互后才能建立起数据承载,减小了数据传输时延。
图2A所示实施例中是通过广播系统信息,将预置数据承载的配置信息发送至移动终端, 而在另一实施例中,还可以通过指定消息将预置数据承载的配置信息发送至移动终端,如图4所示,在RRC连接建立过程中,无线接入网设备在发送给该移动终端的指定消息中携带该预置数据承载的配置信息,相应地,移动终端在RRC连接建立过程中,通过接收该无线接入网设备发送的指定消息,来获取预置数据承载的配置信息。
步骤401:无线接入网设备确定预置数据承载的配置信息。
该步骤401与上述步骤201同理,在此不做赘述。
步骤402:无线接入网设备在与移动终端完成建立无线资源控制RRC连接之前,将该预置数据承载的配置信息发送至该移动终端。
在本申请实施例中,将该预置数据承载的配置信息发送至该移动终端的具体实现方式包括:在RRC连接建立过程中,在发送给该移动终端的指定消息中携带该预置数据承载的配置信息。
请参考图4,在该种实现方式中,在RRC连接建立过程中,无线接入网设备指示移动终端建立预置数据承载,例如,在一种可能的实现方式中,该指定消息为无线资源控制RRC建立消息,也即是,无线接入网设备在RRC建立消息中携带该预置数据承载的配置信息,并通过该RRC建立消息将该预置数据承载的配置信息发送给移动终端。
上述通过不同方式,将预置数据承载的配置信息发送给移动终端,增加了将该预置数据承载的配置信息发送至该移动终端的方式。
步骤403:移动终端在与无线接入网设备完成建立无线资源控制RRC连接之前,接收该无线接入网设备发送的预置数据承载的配置信息。
在该发明实施例中,接收该无线接入网设备发送的预置数据承载的配置信息的实现方式包括:
在RRC连接建立过程中,接收该无线接入网设备发送的指定消息,该指定消息携带该预置数据承载的配置信息。
也即是,当无线接入网设备通过上述指定消息将该预置数据承载的配置信息发送至该移动终端时,对于移动终端来说,接收到该指定消息后,即可从该指定消息中获取到预置数据承载的配置信息。
步骤404:移动终端在与该无线接入网设备完成建立RRC连接之后,基于该预置数据承载的配置信息通过该预置数据承载传输数据。
