Positioning method and system based on wired discontinuous mobile communication network

Technical field

The present invention relates to the field of communications technologies, and in particular, to a positioning technology in wired communication, and more particularly to a positioning method and system based on a wired discontinuous mobile communication network. Background technique '

The existing wired communication network technologies such as PSTN/ISDN have the advantages of good communication environment, rich wired bandwidth resources, high communication quality, simple communication and control technology compared to wireless mobile, and are safe and reliable, but compared with wireless mobile communication technologies, wired communication The fixed fixed, non-removable, and non-shareable features of technology constrain its further and rapid development, making the above advantages of wired communication technology difficult to fully utilize and play, and the fixed, static, dedicated features and existing wired fixed communication technologies do not need to be Unable to implement positioning technology. Wireless mobile communication technology also has its inherent, unavoidable and insurmountable deficiencies and problems, such as lack of radio frequency resources and expensive, poor security and confidentiality, poor communication environment, poor communication quality, high-power RF technology and wireless mobile Communication and control technologies are becoming more and more complex, but because of their wireless and mobile features, they bring great flexibility and convenience to users' communication. The characteristics of wireless mobile features and user equipment and fixed unique numbers can be carried around. And the location of the user equipment needs to be determined frequently, thereby generating wireless mobile communication location service (LCS) and technology, and at the same time, by wireless positioning technology, the performance of the wireless communication system can be optimized and the wireless resource management can be optimized, but due to wireless communication The environment is harsh, the location of users and user equipment is arbitrary and uncertain, and its positioning technology is quite complicated. Not only the types of positioning technologies are very diverse, such as cell ID-based positioning, radio transmission technology based RTT positioning, arrival time TOA or arrival time difference. TDOA , location based on angle of arrival AOA, location based on reference node ROTP, location based on GPS, etc., and also requires a variety of positioning methods based on network, mobile terminal based, network based and mobile terminal assisted, mobile terminal based and network assisted, A large number of complex measurement calculations are required, and if the user moves faster and the delay of the positioning process is large, the result of the positioning process is very likely to be very accurate, but still causes serious positioning error. Summary of the invention The emergence of wired discontinuous mobile communication technology has enabled many advantages of wired communication technology to be fully utilized. At the same time, the characteristics of wired discontinuous mobility, user equipment and fixed unique numbers can also be carried around, and the same needs for users and user equipment. Accurate positioning of the location, coupled with the characteristics of wired access, makes it possible to provide a single, accurate positioning technology based on a wired discontinuous mobile communication network.

It is an object of the present invention to provide a positioning method based on a wired discontinuous mobile communication network, thereby enabling accurate location services in a wired discontinuous mobile communication network.

The location of the access device and its access port is determined. Even if short-range wireless technology is used instead of the wired connection between the user equipment and the user access device, the activity range of the user equipment is limited to the access network user end. Within a few meters, tens of meters, and up to 100 meters near the location of the access device and its access port, The method of the present invention only needs a network-based positioning method to implement location services. Moreover, referring to the practice of the traditional PSTN communication network, even if it is necessary to change the location and re-transfer the installation of the client access device, the user should first report to the operator before the transfer work can be performed by the local engineering personnel, in this case It is necessary to re-survey the new location location information data of the client access device and its access port, and update the access network location function module in time. And related positioning information data in the location service gateway center. Through the cooperation of the user equipment and the communication network, the positioning technology of the present invention can access multiple access modes in the circuit domain or the packet domain, such as message type access, voice type access, client application type access, and Web type access. Waiting for call/session-related positioning, call/session-independent positioning, operation management-type positioning, etc. to implement location services, such as user equipment requesting to query its own location service, network querying the location service of the calling user equipment of the emergency call, location The service client initiates querying the location service of the user equipment.

The positioning method and system based on the wired discontinuous mobile communication network of the invention provide a novel and accurate positioning technology for the user, which changes the existing wired communication technology due to the fixed, static and special deficiencies and cannot and does not need to be realized. At present, the positioning technology of the present invention is based on wired discontinuous mobile communication, so it is very simple and low-cost, and avoids the problem that the existing wireless mobile communication positioning technology is very complicated and inaccurate.
