数据传输方法及装置
本申请要求在2018年09月28日提交中国专利局、申请号为201811141908.9的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及但不限于通信领域，例如涉及但不限于一种数据传输方法及装置。
背景技术
在通信技术中，路测能够反映移动通信网络的状况，对网络性能指标起到直接的测量评估作用，并指出网络的问题所在。路测是运营商进行网络优化的重要手段。传统的路测方法需要运营商或第三方公司对需要监测和优化的区域进行测试，通过路测仪表采集信号电平、质量等网络数据，通过分析这些数据发现网络存在的问题。这种方式往往需要大量的人力、物力和经费投资，同时对网络优化人员也有非常高的经验要求。
最小化路测(Minimization of drive tests，MDT)技术主要是通过终端设备上报的测量报告来获取网络优化所需的层二测量值等相关参数，以达到降低运营商网络优化和维护成本的目的。与传统路测相比，MDT可以节能减排、减少路测开销，缩短优化周期，带来更高的用户满意度，并且可以收集到传统路测无法进行的全区域的测量信息(如窄路、森林、私人场所等)。
最小化路测功能包括：利用用户设备(User Equipment，UE)自动收集层二测量值等测量信息；通过控制面信令报告给无线接入网(Radio Access Network，RAN)，其中RAN可以是对应于E-UTRAN(Evolved UMTS Terrestrial Radio Access Network，演进的UMTS陆地无线接入网)***中的演进基站eNB和NR***中的下一代基站gNB；再通过无线接入网报告给跟踪收集实体(Trace Collection Entity，TCE)。最小化路测用于网络优化，例如发现及解决网络覆盖问题。
根据UE执行MDT测量时所处的状态，MDT的模式还可以分为日志MDT(Logged MDT)和立即MDT(Immediate MDT)。在日志MDT的模式下，UE 在无线资源连接控制(Radio Resource Control，RRC)空闲状态(IDLE)下进行测量记录。在立即MDT(Immediate MDT)的模式下，UE在RRC连接态下进行测量上报。在UE执行MDT测量的情况下，需要的MDT配置信息包括：区域范围Area scope，跟踪参考Trace Reference，UE需要进行的测量类型，以及TCE的IP地址等等。
在5G(Fifth Generation，第五代移动通信)中，基站可分为集中单元(Central Unit，CU)与分布单元(Distributed Unit，DU)两部分，一个基站有一个CU，一个基站可有多个DU，称为集中单元分布单元分离(CU/DU Split)，CU与DU间的接口称为F1接口。CU可以分为CU-CP(Control Plane，CP)和CU-UP(User Plane，UP)，一个CU有一个CP，一个CU可以有多个UP，称为控制面用户面分离(CP/UP Split)，CP与UP之间的接口称为E1接口。相关技术的5G等新无线场景中，终端设备无法实现层二测量值的上报。
