Call Testing Field Remote Control System Design And Implementation

Operation and maintenance of the mobile communication network, the service call is the daily maintenance routine testing and the failure of an important positioning means, with the mobile communication network operation and maintenance deepening degree of centralization, serious failure provinces of inter-firm linkage, Efficient allocation of testing resources, scheduling, allocation and timely feedback and survey information is very important. Allocate existing mobile communication field on the micro-cell test and test operation to open the general maintenance personnel in the engine room directly by the device manual, not only slow, inefficient and must be manually adjusted through the temporary transfer, a serious delay in the fault positioning long. For fast, accurate, and automatically open the test micro-cellular mobile communications field, to avoid the allocation of test personnel manual directly in the engine room equipment, and hand micro-cellular call test, it is necessary to develop a field can be measured remotely open the call and can be remotely controlled micro-cellular call Field test appropriate business phone module test system.Based on currently available micro-cellular devices Ericsson and Huawei proposed a remote control device connected through the exchange of BSC network elements and micro-cellular device transfer port and send commands through the control server power supply automatically turns on the micro-cellular and automatic transmission BSC connected solutions to the mobile communication network maintenance in the existing allocation of the actual work measurement problems.This field were measured around the allocation of power on microcellular system, test equipment, switching and transmission business, and several other aspects of test operations, research and development allocated through the remote control module field testing to address the allocation process of measuring open field manual, time-consuming and complicated disadvantages, the design of the remote control Call Testing field system has the following properties:1, dial the remote turn-on time measurement field is less than 2 minutes; 2, Call Testing field to switch between network elements less than 0.1 seconds; 3, the monitoring center in the OMC Open Call Testing remote field equipment; 4, remote control room can be allocated in the OMC test field for business phone call test module. This system has reduced positioning time troubleshooting, reducing the manpower required for the business objectives of measurement aside.In this paper, "Call Testing Field Remote control system design and implementation" as the subject, do the following work:1) given the current network operation and maintenance in the process of allocation of fault location test market the need for remote automatic control analysis.2) introduced the Ericsson and Huawei BTS3002C RBS2302 two micro-cellular structure, characteristics. 3) compare the current field measurement system functions have been allocated for application requirements put forward a new design.4) Measured based on market demand allocation scheme, designed and developed to achieve the allocation of the remote control system field test.5) The paper summary and outlook.
