【正文】 highway. The traffic on the highway not only have broken even and smooth state, but also the function of the routing addressing. 4). SCCP signaling connection control layer and layer MTP3 together corresponds to the work layer of the OSI model. Signaling connection control part is the purpose of strengthening the function of the message transfer part (MTP), which together with the MTP3 constitute NO. 7 signalling work layer, for signal transmission in the work39。s ability to provide work address forwarding. Above are some basic knowledge about the ss7, mobile munication technology is not only to the correct application of these technologies, and later maintenance and management, etc., ss7 can also provide help in this regard, mainly according to the system, the manmachine mands and MPTMON mand shows the query NO. 7 signalling system status, locate the fault quickly, then excluded, as to the content of the maintenance in the not much said. Conclusion: ss7 applications are very broad, it is because of its fast transmission, large capacity, and support the business expansion, these characteristics on the one hand, meet the demand of the current society, at the same time, the future development of munication technology is also to the expansion of business, these needs NO. 7 signalling can meet the basic, so widely used. A call connection, disconnect, dial tone, tone, road monitoring, are signaling under the control of the results. A nutshell, signaling, the nerve center of munication, status is very important. The definition of NO. 7 signalling system NO. 7 signalling is a kind of bureau signaling between digital total road. In NO. 7 signalling system, the signal information can be associated with a group of circuits of signal information or other information for work management, therefore, NO. 7 signalling system is essentially used to transfer information between each processor in the telemunication work data munication system for special purpose, and NO. 7 signalling work as a munication work of supporting work also can be regarded as a relatively independent data munications work. Signaling system is an important part of munication work, it is the user and the munication work in various nodes exchange information of the mon language. Signaling according to its work area is divided into user signaling and interoffice signaling. User signaling is signaling between the user and switches, interoffice signaling is signaling between the switches, interoffice signaling according to the transmission methods can be divided into signaling and road signaling. The advantages of NO. 7 signalling system The advantages of NO. 7 signalling system NO. 7 signalling system is most suitable for posed of digital programcontrolled switches and digital transmission equipment integrated digital work, and can meet the present and the future transmission call control, remote control, maintenance and management signaling and transaction information between processor39。s request, provides the reliable method, make the signal transmitted in the correct order and not be lost or repeat. NO. 7 signalling system USES highspeed data link (64 kbit/s) transmit signal, signaling links is a bidirectional path of sending signaling messages between signaling points, by the data link and data link terminal at the ends of the circuit to plete the NO. 7 signalling system function structure of the secondary function. NO. 7 signaling data link with transmission speed, call setup time is short, large capacity, signal changes with flexible expansion, signaling equipment investment, high utilization rate of speech path, etc. In No. 7 signalling system in SPC exchange, we can enjoy a variety of service functions, including the Lord called number recognition, busy callback, call waiting, don39。t disturb, alarm service, malicious call tracing, three calls, conference calls, etc. No. 7 signalling system can transmit in the work call control maintenance and management, statistics, billing, and other information, suitable for integrated services digital work (ISDN) and the use of smart grid and other new business. Signaling centralized operation and work management system In our country currently USES two levels of No. 7 signalling work management structure, the first level for the No. 7 signalling work management center, is located in the electrical work management center, responsible for the management of HSTP and C1 and C2 level main No. 7 signalling work. Level of main line No. 7 signalling work work management system by the EDPC (electronic data processing center) and NSC (work operations center), EDPC including the operating system (0 s), intermediate devices (MD), workstation (WS). NSC is which has the function of operation management and maintenance of the centralized maintenance center (0 a amp。 M), between it and the HSTP adopt the No. 7 link and x. 25 link connection, No. 7 news management link is used to pass SP points. C1 and C2 longdistance bureau through the No. 7 signaling links are connected to the NSC, system mainly plete: the No. 7 signalling work work structure graphics display。 For No. 7 signalling work configuration for production and modification operations。 The No. 7 signalling work incident reports and the corresponding malfunction alarm。 For No. 7 signalling work performance data for statistics and can read the work status data and determine the performance of work, such as business data collection, the determination of traffic and load, business reports。 The NSC maintenance and management。 0 MRVT test of the map. Secondary to the provincial capital and municipality directly under the central government: No. 7 signalling work management center is located in the provincial bureau of the work management center, responsible for managing in this province (muni
