product description
Expanding communications market enabling users rely on the communications network has been strengthened; the opening of new services, as well as the diversity that exists telecommunications equipment, telecommunications network to improve the quality and maintenance of the network with the increasing demands put forward. the development of communication technology, the current widespread use of SS7 network has become a modern communication network supporting network. SS7 is one of the key technologies of modern communication network through the SS7 communications network ' Neurons' monitoring and analysis, we can determine the level of quality of telecommunications network operation. Therefore, the construction of an integrated, multi-purpose, multi-level monitoring system has a very important significance.
With the emergence of new technologies, telecom services are also increasingly rich, from traditional voice services to today's voice, data, IP, intelligent network service number coexistence signaling network technology system naturally and future network evolution trends are closely related. From traditional voice services to present data services, IP services, face continued convergence SS7 network, needs to be a means of early prevention of maintenance that exist to deal with network problems, in order to ensure healthy development of the network, promote the development of the business. VII signaling network monitoring and analysis system is to build barriers and bottlenecks of network communication, service and tendencies risks and error data network services, transfer and differentiation of network traffic, network operations provide raw performance data have decisive significance. Different departments NMC statistics are based on reasonable adjustments related to the allocation of resources network, which provide users with efficient, safe and reliable guarantee of modern communication.

System Features
(1) common good. Centralized SS7 Monitoring System monitoring and analysis of the seventh letter of international ITU standard, regardless of the telecommunications network equipment NE, therefore, common good, not the network element equipment suppliers Restriction.

(2) monitor the whole network. Because universal signaling No.7 concentrative monitor system is good, so that the application can monitor all local network or the provincial network, the national network SS7 links.

(3) real-time monitoring. Running real-time monitoring of the signaling network, telecommunications network connection rate, Hu called tracking telecom business processes.

(4) strong monitoring function signaling network fault monitoring, condition monitoring, network performance analysis, network failure foreseeable risks, analysis of network failures; telephone network connection rate analysis, Hu loss analysis, Hu called tracking, Hu called inquiries.

(5) the signaling network interface is simple. Centralized SS7 monitoring system through the 'impedance matching device' is connected across the high impedance VII signaling link, does not affect the operation of the SS7 network.

Structure and Function
Centralized SS7 monitoring system consists of data acquisition devices, data storage devices and data analysis device integration through the network system consists of three parts made of concrete to complete remote, WAN, remote central station: each remote station by a the normal operation of a remote processor and several sets of configuration data acquisition module front end machine. remote acquisition module configured to collect data directly from the high-impedance adapter test port VII signaling link, does not affect the link . WAN: responsible for connecting remote stations and the central station to transfer data between the two can be connected to DDN, DCN, 2Mb / s lines, internal corporate network and other wide area network hub: located in the network management center, from the graphics workstations and central servers complete centralized monitoring system operation and maintenance functions.

Front-end access
In order to achieve Centralized SS7 signaling network monitoring system for monitoring purposes, the seventh letter must focus on building a reliable connection between the monitoring system and the SS7 network.
STP (signaling transfer point) is a signaling network core equipment, signaling network signaling links are basically related with STP, while according to the national standard recommendation, signaling link must be carried out by compliance with G. 703 standard E1 systems transmission, so No.7 Signaling Monitoring System usually by STP signaling links where the E1 system monitoring to achieve. E1 system needs to connect through the DDF and the DDF can provide test port, so the current common implementation STP connection practice is carried out in a high-impedance bridging the DDF, which we call 'decentralized access' or 'hard-wired'.
According to the current national standard recommendation, signaling link between two signaling points should be evenly distributed in at least two different transmission channels of E1 system, each E1 transmission 4-6 recommend signaling links. That is two the opening of a signaling link between a signaling point need at least two E1 system, if the signaling link more appropriate to increase the number of E1, the corresponding E1 interface signaling monitoring the number should be increased, this will cause costs improve. and can not be time-division multiplexing 31 E1 timeslots system. To solve this problem, increase the DXC (slot convergence device) equipment and front-end machine components DXC remote configuration management system to improve the utilization of E1, and by this system, users can dynamically select the link to be monitored.

Access uses the following security measures:

(1) The high impedance technique: impedance is greater than 2k.

(2) Isolation: irreversible coupling coil.

(3) the adaptation: improve waveform, suitable for long distance transmission (up to 1000 m).

(4) Safety distance: barrier from the adapter and the monitoring point distance of not more than 100 mm, so as not to affect the test link.

Any outside interference signals are barrier adapter isolated from the outside, does not affect the normal operation of VII signaling link, and with the long-distance test line, meet the needs of field-tested, so remote and test points may not necessarily be placed in together.

Data acquisition and storage
Complete remote signaling data acquisition and pre-processing functions, data preprocessing completion of data collection roughing, that signaling messages are classified according to different categories will receive the message synchronized to the central monitoring subsystem different database tables in. For example, the alarm failure warning failure data into data tables, link state data into the data link state table, TUP TUP message on the message table, ISUP message into ISUP message table and so on.

Processing data analysis

Center monitoring subsystem to complete a comprehensive analysis of the system data processing, the specific function of the system to achieve the following functions:

(1) SS7 network running real-time monitoring: Expand any one link are analyzed in detail on monitoring each link Erl, MSU change, MTP / SCCP / TCAP performance monitoring, detailed plots each link Erl change curve, network performance and problem analysis, multi-load curve.

(2) Performance management and network assessment: abnormal messages on statistical link management, link alarm management functions.

(3) TUP phone users centralized maintenance management: Hu loss analysis reports, connection rate curve analysis, management reporting phone users sparse busy, busy users to multi-day statistics, Hu called telephone user queries.

(4) telephone real-time accounting assistant management: GSM signaling network associated with the MTP signaling billing, Hu called tracking and inquiry, real-time online measurement, monitoring hotline international 'friends' interception, international long distance 'call-back' monitoring interception, Hu called monitoring international and domestic short.

(5) Los monitor signal line is not working and processing: with Web browser access, Hu called with a cross-section of tracking and monitoring, centralized monitoring system resource management, monitoring system equipment management, maintenance and management of the system itself, with local network management system networking, can be networked with the province SS7 network network monitoring systems.

Centralized SS7 monitoring system can provide network signaling and telecommunications network maintenance, network optimization, and high-level support three aspects of value-added applications.

(1) Network maintenance support. VII signaling signaling network monitoring system to achieve a perceived failure in advance and pre-warning, trouble-free operation of safety nets to help maintenance personnel from a current fault reporting type of maintenance mode to the integrated management of type Maintenance mode change. VII signaling gateway linking features, the use of existing technology (instrumentation and network management system) is difficult to fault occurred on the network to locate and diagnose, and therefore only through Centralized SS7 Monitoring system to solve.

(2) network optimization and planning support SS7 network as carriers of the huge investment required and reasonable allocation of network performance optimization, thereby protecting investment and improve the professional level and quality of service, increase operational investment purposes.
