背景技术
为了更好地服务终端用户，目前提出了一种网络设备之间协同的技术方案。譬如，当某个终端用户处于第一网络设备与第二网络设备之间的交叉覆盖区域时，可以通过第一网络设备与第二网络设备之间的协同功能来实现提高该终端用户的接收信号强度，降低信号干扰。其中，第一网络设备与第二网络设备之间协同的实现依赖于第一网络设备与第二网络设备之间的数据传输。
目前，第一网络设备与第二网络设备之间的数据传输的方式仅能适用于部分范围内的网络设备之间的数据传输，不能适用于更为广泛的网络设备之间的数据传输。
发明内容
本申请提供一种数据传输的方法、通信装置以及系统，能够实现更为广泛的网络设备之间的数据传输。
第一方面，提供了一种数据传输的方法，该方法应用于第一网络设备侧，该方法包括：确定第一数据，第一数据的目标接收对象是第二网络设备；向核心网网元发送第一数据，核心网网元用于将第一数据转发至第二网络设备。
应理解，核心网网元具有与第一网络设备以及第二网络设备进行通信的能力，核心网网元能够将第一网络设备向其发送的第一数据转发给第二网络设备。
本申请支持由核心网网元进行网络设备之间的数据转发，实现网络设备之间基于非私有信息的数据传输，能够实现更为广泛的网络设备之间的数据传输。通过由核心网网元实现网络设备之间的数据传输，可以使得不同厂商之间能够形成网络设备之间数据传输的互通机制。
同时，由于不同的厂商基于各自的私有信息进行数据传输的带宽开销不同，会对网络设备配套的承载网的带宽造成差异化的需求，这会增加承载网建设的复杂度，通过采用核心网网元进行数据转发的技术方案，本申请能够降低承载网建设的复杂度。

图1是本申请实施例的适用通信系统100的示意图。如图1所示，通信系统100包括网络设备110、网络设备120以及核心网网元130。应理解，本申请实施例对通信系统100所包括的网络设备的数量不做限定。图1仅作为示例性理解，并不能限定本申请所要求的保护范围。其中，网络设备110与网络设备120可以是如上所列举的任意一个网络设备。
图1中，网络设备110与网络设备120之间可以存在直连通信的通信链路1(也可以为直连接口)，也可以通过核心网网元130实现网络设备110与网络设备120之间的数据传输。譬如，网络设备110向核心网网元130发送数据1，核心网网元130向网络设备120发送数据1。相应地，网络设备120向核心网网元130发送数据2(图1未显示)，核心网网元130向网络设备110发送数据2(图1未显示)。
应理解，网络设备110或者网络设备120与核心网网元130之间的通信接口可以为5G通信系统中的Ng接口，也可以是其他类型的接口，譬如，LTE通信系统中的S1接口，其能够实现网络设备110或者网络设备120与核心网网元130之间的通信，本申请对此不限定。另外，网络设备110与网络设备120之间的通信接口为直连接口，其能够实现网络设备110与网络设备120之间的直连通信。其中，该直连接口在不同的通信系统中可以有不同的名称。譬如，该直连接口在LTE通信系统中为X2接口，在5G通信系统中为Xn接口，等等。

由前文描述可知，网络设备110与网络设备120之间的协同功能的实现需要依赖网络设备110与网络设备120之间的数据传输。其中，网络设备110与网络设备120之间的数据传输可以是基于私有信息实现的。其中，该私有信息可以为由不同厂商各自设定的信息类型。换言之，不同厂商的私有信息(一般)是互不相同的。譬如，厂商1所设定的网络设备110与网络设备120之间进行数据传输的私 有信息是信息1，厂商2所设定的网络设备110与网络设备120之间进行数据传输的私有信息是信息2，信息1不同于信息2。如此，这会使得网络设备之间的数据传输仅能适用于部分范围内的网络设备之间的数据传输(即属于同一个厂商的网络设备之间的数据传输)，不能适用于更为广泛的网络设备之间的数据传输(即属于不同厂商的多个网络设备之间的数据传输)。
有鉴于此，本申请提供一种数据传输的方法、通信装置以及系统，能够实现更为广泛的网络设备之间的数据传输。
下文将结合附图对本申请实施例的数据传输的方法进行描述。
图2是本申请实施例的数据传输的方法200的交互流程示意图。图2中的方法流程可以由网络设备110、网络设备120以及核心网网元130执行，或者由安装于网络设备110、网络设备120以及核心网网元130中具有相应功能的模块(例如，网络设备中的CU、CU-CP或者BBU等)和/或器件(例如，芯片或集成电路等)执行，本申请不做限定。下文以网络设备110、网络设备120以及核心网网元130为例进行说明。如图2所示，方法200包括：
S210、网络设备110确定数据1。
具体而言，网络设备110所确定的数据1的目标接收对象是网络设备120。
一个可能的实现方式，数据1用于指示网络设备110的配置信息#1与网络设备120的配置信息#2中的至少一项。

示例性地，数据1所指示的配置参数包括心跳数据时，其能够用于保证两个网络设备中的其中一个网络设备出现设备故障时，另一个网络设备能够快速、准确、及时地进行网络设备倒换；再比如，数据1所指示的配置参数包括网络设备的控制指令时，其能够用于实现两个网络设备之间的联合调度，从而控制好两个网络设备的功率、波束、空口资源调度，以及还能够提升两个网络设备的交叠区域的网络信号质量以及对应区域的终端吞吐率等等。

具体来说，数据1指示网络设备120的配置信息#2时，网络设备120可以根据网络设备110的指示对网络设备120的配置参数进行调整(譬如，调整网络设备120的链路状态、功率状态以及波束赋形等等)，如此，网络设备120可以更为准确地实现二者的协同功能。
可选地，配置信息#1还可以包括配置信息#2。具体地，除了向网络设备120指示自身的配置参数外，网络设备110还可以向网络设备120指示网络设备110为网络设备120配置或者建议的配置参数，如此，可以更好的实现二者的协同功能。譬如，网络设备110与网络设备120同时为一个终端设备提供通信服务时，网络设备110与网络设备120之间可以协同彼此的功率状态(通过上述的配置信息#1或者配置信息#2的方式)，实现最佳的通信服务效果，且还可以避免功率浪费或者功耗浪费。
综上，通过上述的数据1所指示的配置信息#1与配置信息#2中的至少一项，本申请支持更好地实现网络设备110与网络设备120之间的协同功能。同时，本申请也支持网络设备110与网络设备120之间互为彼此备份的冗余备份功能的实现(将在下文进行描述)。
应理解，网络设备110与网络设备120之间的协同功能或者备份功能的实现均需要依赖于网络设备110与网络设备120之间的数据传输。
一个示例中，数据1包括用户数据1，其用于指示网络设备110与其所服务的终端设备之间的通信业务数据。
一个可能的实现方式，数据1满足周期性特征。其中，该周期性特征用于指示网络设备110周期性地向核心网网元130发送数据1。
一个可能的实现方式，数据1满足非周期性特征。其中，该非周期性特征用于指示网络设备110非周期性地向核心网元130发送数据1。
S220、网络设备110向核心网网元130发送数据1。
相应地，核心网网元130接收来自于网络设备110的数据1。
应理解，数据1的源发送对象是网络设备110，数据1的目标接收对象是网络设备120。数据1经由核心网网元130到达网络设备120。
本申请中，核心网网元转发网络设备的数据时，可以是透明转发，也可以是加工后转发(例如增加包头后打包转发)，不予限定。
具体而言，网络设备110与核心网元130之间的数据传输可以是基于第三代合作伙伴项目(the 3rd generation partnership project，3GPP)38.413协议实现的。其中，上述的数据1也可以采用3GPP协议中规定的信息格式进行传输。譬如，数据1采用3GPP协议中的上行无线接入网络配置信息转发(uplink radio access network configuration transfer，UPLINK RAN CONFIGURATION TRANSFER)的信息格式，本申请对此不做限定。
应理解，上述的网络设备110向核心网网元130发送的数据1可以被包括在UPLINK RAN CONFIGURATION TRANSFER信息中，也可以采用和UPLINK RAN CONFIGURATION TRANSFER信息的格式相同的其他信息进行传输，本申请对此不做限定。

通过上述技术方案，本申请支持由核心网网元130向网络设备120转发网络设备110发送的数据，如此，能够实现网络设备110与网络设备120之间的数据传输。
具体来说，本申请支持由核心网网元130进行网络设备110与网络设备120之间的数据转发，能够实现网络设备110与网络设备120之间基于非私有信息的数据传输，能够实现更为广泛的网络设备之间的数据传输。通过由核心网网元实现网络设备之间的数据传输，可以使得不同厂商之间能够形成网络设备之间的数据传输的互通机制。
同时，由于不同的厂商基于各自所设定的私有信息的带宽开销不同，会对网络设备配套的承载网的带宽造成差异化的需求，这会增加承载网建设的复杂度，通过采用核心网网元进行数据转发的技术方案，能够降低承载网建设的复杂度。
一个可能的实现方式，方法200还可以包括：

相应地，网络设备120接收来自于核心网网元130的数据1。
