Description

一种北向接口LTE业务自动配置方法、北向接口装置及存储介质 技术领域
本公开涉及移动通信技术领域，特别涉及一种北向接口LTE业务自动配置方法、北向接口装置及存储介质。
背景技术
3G网络向LTE(Long Term Evolution，长期演进)演化为当今移动通信技术发展的一大趋势，LTE相对于传统的2G/3G网络，其最大特点是网络扁平化，并引入了S1和X2接口，如图1所示：
2G/3G网络架构下，一个BTS(Base Transceiver Station，基站收发台)/NodeB只能同时归属于一个BSC(Base Station Control，基站控制器)/RNC(Radio Network Controller，无线网络控制器)，流量呈汇聚形；BTS/NodeB之间无网络连接；
LTE的网络架构下，一个eNB(Evolved Node B，演进型Node B)同时归属多个MME(Mobility Management Entity，移动性管理实体)/S-GW(Serving GateWay，服务网关)；eNB之间采用X2接口方式直接互连，流量呈Mesh型；eNB与MME/S-GW之间通过S1接口连接；S1业务流量占整个RAN(Residential Access Network，居民接入网)流量的比例在97％以上，X2业务流量占比则小于3％。其中：
S1接口设置于eNB-aGW之间，负责用户UE的高清视频点播、高清视频监控、实时RGB在线游戏、音乐下载和移动电视、高速上网等用户业务的连接承载，S1接口需要灵活的调度能力，使eNB(Evolved Node B，即演进型Node B简称eNB)可以灵活的归属到多个aGW(ASN Gateway，ASN网关)；
X2接口设置于相邻的基站eNB之间，与2G/3G Backhaul(回程线路)网络的星形架构不同，LTE Backhaul增加了对X2接口的承载需求，要求支持部分Mesh架构，需要在相邻基站之间建立逻辑连接，以负责用户在不同eNB间漫游时，用户数据可以在eNB间直接进行交换。
目前对于LTE移动回传业务的承载，主要采用PTN(Packet Transport Network，分组传送网)或IP RAN(Radio Acess Network，无线接入网)设备进行组网，典型的PTN或IPRAN可划分为核心层、汇聚层、接入层三级结构，并且采用L2VPN(Layer 2 Virtual Private Network，二层虚拟专网)+L3VPN(Layer 3 Virtual Private Network，三层虚拟专网)桥接的承载方案，其组网图如图2所示。通常在接入层和汇聚层使用L2VPN承载，即从基站接入网元到L2/L3桥接网元布署L2VPN网络；核心层则使用L3VPN承载，即从L2/L3桥接网元到与aGW相连网元布署L3VPN网络，在L2/L3桥接网元上需要进行桥接配置；L3VPN网络一般进行Full Mesh(全连通)组网，并且L3VPN业务会预先布署好。
随着4G基站的大量铺设，需要将新设基站开通大量的数据业务。目前运营商采用的都是半自动化的操作，通过综合网管预先进行业务规划，包括接口IP地址规划、业务VLAN规划、路由及保护规划及业务带宽等规划。综合网管完成好上述规划后，再制作一张业务开通工单，在此业务开通工单中包含了这些规划数据，然后将此工单下发给设备厂商网管的运维人员。运维工员根据工单需求通过EMS(Element Management System，网元管理系统)网管人工操作单步单步操作完成业务的开通，一般包括在桥接网元上创建二层及三层虚接口、创建二三层桥接、创建三层子接口、创建L2VPN端到端业务、将L2VPN业务引入到创建好的L3VPN业务中、配置静态路由表、配置VPN-FRR/IP-FRR(Fast Reroute，快速重路由)保护等。EMS网管界面步骤多且非常复杂，另外因不同的设备厂商或即使是同一设备厂商的不同设备间存在设备差异性，对运维人员要求非常高，不但要熟悉业务知识，并且能熟练操作厂商网管。运维人员根据工单开通业务后，需要知会综合网管操作人员，综合网管再通过厂商北向接口将新开通的业务查询上去并进行入库。另外，综合网管还需对厂商运维人员创建的业务的连接性、丢包率、延时以及业务路由进行检查，以判断新创建的业务是否满足要求。如不满足要求，需要厂商运维人员删除此业务并重新按要求创建业务，重复上述步骤，直至满足要求为止。整个LTE业务的开通流程及其复杂，人工操作容易出错，导致效率非常低下。中国发明ZL201510010339.4“一种PTN二层转三层业务场景下的业务配置方法及系统” 公开了一种PTN二层转三层业务场景下的业务配置方法及系统，按照设备组网定制不同的业务场景模板，再根据不同的业务场景模板定制不同的业务参数来完成业务的端到端配置，但不能自动针对不同的设备厂家进行操作订制，接口定义与接口实现无法解耦，LTE业务配置不够简化和透明。
综上所述，相关的综合网管半自动的LTE业务开通方式难以满足日越增长的4G业务的需求，也不符合运营商集约化管理需求。
