Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to an automatic configuration method of a northbound interface LTE service and a northbound interface device.
Background
The Evolution of the 3G network to LTE (Long Term Evolution) is a major trend of the development of the current mobile communication technology, and compared with the conventional 2G/3G network, LTE has the biggest characteristic of network flattening and introduces S1 and X2 interfaces, as shown in fig. 1:
under 2G/3G Network architecture, one BTS (Base Transceiver Station)/NodeB can only belong to one BSC (Base Station Controller)/RNC (Radio Network Controller) at the same time, and the flow is in convergence; no network connection exists between BTS/NodeB;
under the network architecture of LTE, one eNB (Evolved Node B) simultaneously belongs to multiple MMEs (Mobility Management entities)/S-GWs (Serving GateWay); the eNBs are directly interconnected by adopting an X2 interface mode, and the flow is Mesh type; the eNB is connected with the MME/S-GW through an S1 interface; the proportion of the service flow of S1 to the flow of the entire RAN (Residential Access Network) is more than 97%, and the proportion of the service flow of X2 is less than 3%. Wherein:
the S1 interface is arranged between the eNB and the aGW and is responsible for connection and bearing of user services such as high-definition video on demand, high-definition video monitoring, real-time RGB online games, music downloading, mobile television, high-speed internet access and the like of user UE, and the S1 interface needs flexible scheduling capability, so that the eNB (Evolved Node B, namely Evolved Node B (eNB for short) can flexibly belong to a plurality of aGWs (ASN Gateway);
the X2 interface is disposed between adjacent base stations eNB, which is different from the star architecture of 2G/3G Backhaul (LTE Backhaul) network, LTE Backhaul increases the bearer requirement for the X2 interface, requires to support part of the Mesh architecture, and needs to establish logical connection between adjacent base stations to be responsible for direct exchange of user data between enbs when a user roams between different enbs.
At present, for the bearer of the LTE mobile backhaul service, a Packet Transport Network (PTN) or a Radio access Network (IP RAN) device is mainly used for networking, a typical PTN or IP RAN may be divided into a core Layer, a convergence Layer, and an access Layer three-level structure, and a bearer scheme bridged by an L2VPN (Layer 2Virtual Private Network) + L3VP N (Layer 3Virtual Private Network) is used, and a networking diagram of the bearer scheme is shown in fig. 2. L2VPN bearers are typically used at the access and convergence layers, i.e. the L2VPN network is deployed from a base station access network element to an L2/L3 bridging network element; the core layer uses L3VPN load, namely an L3VPN network is arranged from an L2/L3 bridging network element to a network element connected with aGW, and bridging configuration is needed on an L2/L3 bridging network element; l3VPN networks typically perform Full Mesh (Full connectivity) networking and L3VP N traffic will be pre-deployed.
With the massive laying of the 4G base stations, a large amount of data services need to be opened for the newly-set base stations. At present, operators adopt semi-automatic operation, and perform service planning in advance through comprehensive network management, including interface IP address planning, service VLAN planning, routing and protection planning, service bandwidth planning and the like. After the comprehensive network manager finishes the planning, a service opening work order is manufactured, the service opening work order contains the planning data, and then the work order is issued to operation and maintenance personnel of the network manager of the equipment manufacturer. An operation and maintenance worker manually operates a single-step operation to complete service provisioning through an Element Management System (EMS) according to a work order requirement, and generally includes creating a two-layer virtual interface and a three-layer virtual interface on a bridging network Element, creating a two-layer bridge and a three-layer bridge, creating a three-layer sub interface, creating an L2VPN end-to-end service, introducing an L2V PN service into the created L3VPN service, configuring a static routing table, configuring VPN-FRR/I P-FRR (Fast Reroute) protection, and the like. The EMS network management interface has many and very complex steps, and has very high requirements on operation and maintenance personnel due to equipment differences among different equipment manufacturers or even different equipment of the same equipment manufacturer, so that the EMS network management interface not only needs to be familiar with business knowledge, but also can be skillfully operated by the manufacturer network management. After the operation and maintenance personnel open the service according to the work order, the operation personnel of the comprehensive network management is required to know, and the comprehensive network management inquires the newly opened service through the northbound interface of the manufacturer and stores the newly opened service in a warehouse. In addition, the integrated network manager also needs to check the connectivity, packet loss rate, delay and service route of the service created by the operation and maintenance personnel of the manufacturer to determine whether the newly created service meets the requirements. If the requirement is not met, the operation and maintenance personnel of the manufacturer are required to delete the service and create the service again according to the requirement, and the steps are repeated until the requirement is met. The whole LTE service opening process is extremely complex, manual operation is easy to make mistakes, and the efficiency is very low. China' ZL201510010339.4 "service configuration method and system under a PTN two-layer to three-layer service scenario" discloses a service configuration method and system under a PTN two-layer to three-layer service scenario, customizing different service scenario templates according to device networking, and then customizing different service parameters according to different service scenario templates to complete end-to-end configuration of services, but it cannot automatically perform operation customization for different device manufacturers, interface definition and interface implementation cannot be decoupled, and LTE service configuration is not simplified and transparent enough.
In summary, the existing semi-automatic LTE service provisioning mode for integrated network management is difficult to meet the increasing requirements of 4G services, and also does not meet the intensive management requirements of operators.
