以上现有技术的缺点在于：
(1)现有的5G无线通信网络架构，5G基站ngNB与核心网5GC是独立部署，而5G基站ngNB采用专用硬件，部署在靠近用户的区域，5GC核心网采用NFV/SDN平台，5GC核心网部署的硬件，一般是X86处理器平台。根据3GPP定义的Release15版本，5GC核心网是基于独立的硬件体系架构，5G基站ngNB也是基于独立的专用硬件架构，两个大的系统之间，采用N1/N2/N3接口完成互联，相对独立。部署的硬件资源/网络资源等采用独立分配。
(2)5G无线通信网络的MEC边缘计算，目前5G边缘计算中，并没有很好的将无线与核心网UPF的功能很好结合起来，在物理部署距离，或者是逻辑部署距离方面，都很大的隔离，影响MEC在实际的网络中的实施，将影响后续的5G在MEC功能上，在垂直行业的应用。
(3)特别是5G边缘计算MEC的方法中，更多的考虑是功能，比如用户面数据的卸载，用户面的计费等基本功能，没有实际考虑在卸载/计费/转发的高性能，以及基站与5GC核心网GTP-U(GTP-U是GTP协议的一种，用于在GPRS核心网内，无线接入网与核心网之间传送用户数据)数据面模块的合并处理等。

与本实施例的5G基站对应的数据报文处理流程如图4所示，数据报文的处理主要依靠5G基站的以下部件：硬件平台101、PDCP(Packet Data  Convergence Protocol分组数据汇聚协议层)模块203、基站GTP编码解码器201、核心网GTP编码解码器202和5GC核心网的用户面功能UPF204。201部件在实际部署是203部件的一部分，201和203是图3中103的一部分；202部件是204部件的一部分，202和204合在一起就是图3中的102，为了方便描述分开来表示。
本实施例的数据报文处理方法包括上行数据报文处理的步骤和下行数据报文处理的步骤：

步骤S206、硬件平台101的物理层L2处理完成后，即完成5G无线资源管理等处理后，将该数据报文通过空中接口发送手机用户。
实施例二
与实施例一不同的是，数据报文的处理方法中去掉了201部件和202部件及其处理数据报文的步骤，即去掉了基站GTP-U编码解码器和核心网GTP-U编码解码器的编码和解码的过程，简化了5G基站ngNB和5GC核心网UPF网元之间的N3接口。
本实施例中，其数据报文的处理流程如图5的虚线①所示，其上行数据报 文步骤如下：
步骤S101’、101部件的L2物理层收到来自无线空口手机用户终端UE的数据报文，经过处理后发给部件203；

步骤S204’、硬件平台101的物理层L2处理完成后，即完成5G无线资源管理等处理后，将该数据报文通过空中接口发送手机用户。
在5G网络，除去ngNB和UPF之间N3接口的GTP数据解封装功能，大大提升5G数据面的处理速度，降低数据面处理时延和数据传输抖动等。
实施例三
在实施例二的基础上，增加了功能单元的处理流程，功能单元包括分类处理模块301、分类规则生成器304、由MEC边缘计算模块和计费CDR统计处理模块组成的计算和计费处理模块302，这是3GPP协议与规范所不具有的特性。

其中，分类的步骤包括：301部件收到来自203部件的上行数据报文或者204部件下行数据报文，根据304生成的分类规则对接收到的数据报文进行分类处理后返回给相应的部件。
其中，304部件是对301部件的分类规则进行编辑，完成后发送给301部件，301部件执行304部件下发的规则；304部件，产生的规则，基于5G基站ngNB和5GC核心网UPF以及SMF/AMF所需求的应用以及当前互联应用OTT所具有的特殊性质所呈现。
计算和计费处理的步骤包括：302部件接受来自203部件、204部件、301部件中的一个以上的IP数据报文，进行MEC边缘计算处理或者计费CDR接口处理后返回给相应部件，满足当前边缘计算/特殊计算/专用数据报文分类识别 处理等。
