Problems solved by technology

At present, in some mobile communication networks, such as: Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Universal Mobile Telecommunications System (UMTS), etc., have the ability to locate users. However, since the coverage of base stations in networks such as GSM and UMTS generally ranges from 500m to 1000m, the location of the user can only be determined within 1 kilometer. without getting more precise location information
Relatively speaking, the coverage area of ​​WLAN access points is much smaller, only tens of meters, but there is no specific solution for the provision of user location information in WLAN.

Embodiment approach

[0024] An implementation manner of obtaining the location information related to the access point to which the user terminal belongs in step b of the above method includes:

[0025] b11. After the location management subsystem receives the user location information request from the client application, the management unit sends the user wireless LAN location information request to the location information detection unit in the corresponding destination user terminal;

[0026] b12. After the location information detection unit in the target user terminal receives the user wireless LAN location information request, it returns the user wireless LAN location information request response to the management unit of the location management subsystem, and the response carries the target user terminal Access point identification information of the current access point.

[0027] Wherein, step b11 further includes: after the positioning management subsystem receives the user location infor...

Embodiment 1

[0065] Since the access point identification information usually obtained by the location management subsystem is not the location information that can be directly identified or used by the client application, in order to provide the client application with more convenient and intuitive location information, such as Figure 4 As shown, a location information conversion unit can be added to the basic positioning management subsystem to convert the obtained identification information of the access point into a specific geographic location in the form of latitude and longitude plus altitude that can be recognized by the client application terminal , or geographical location area name, or the information format of building area name. The location information conversion unit is connected to the management unit, and the management unit is responsible for controlling the information interaction and message delivery process of the location information conversion unit; it can also be di...

Embodiment 2

[0067] In the actual user positioning process, the location information of each user terminal can be obtained by the location management subsystem in real time when the client application side has a request; it can also be stored in the location management subsystem in advance. In the system, when necessary, it is directly obtained from the stored information. Therefore, if Figure 5 As shown, in order to store the location information of the user terminal, a location information storage unit may be added to the basic positioning management subsystem, and this unit may be a memory or a database. The location information storage unit is connected to the management unit, and the management unit is responsible for controlling the information interaction and message delivery process of the location information storage unit; it can also be directly or through the management unit. The obtained location information of the user terminal is sent to the location information storage uni...

Abstract

The present invention discloses a user positioning system for Wireless Local Area Network (WLAN), comprising more than one User Equipment (UE) and a WLAN access part, and further comprising a positioning management subsystem for acquiring position information of WLAN users and providing the desired user position information to an application client which requests position information to the positioning management subsystem. Here, the positioning management subsystem is connected with both of the UEs and the application client. The positioning management subsystem further comprises a management unit for controlling information interaction course inside the positioning management subsystem and that between the positioning management subsystem and the outside, and a positioning information detection unit connected with said managing unit and used for acquiring user's position information and detecting change of user's position information. A method for implementing user positioning with the above system is disclosed also in the present invention. User positioning function in WLAN can be implemented with this system and method, and a high user positioning precision can be provided.

Description

technical field [0001] The invention relates to a user positioning technology in mobile communication, in particular to a user positioning system suitable for a wireless local area network and a method for realizing user positioning. Background of the invention [0002] As users have higher and higher requirements for wireless access rate, Wireless Local Area Network (WLAN, Wireless Local Area Network) emerges at the historic moment, which is based on IEEE 802.11b / a standard and can provide high-speed Technology for wireless data access. Among them, IEEE802.11b usually uses the 2.4GHz frequency band, while IEEE802.11a uses the 5GHz frequency band, and IEEE802.11b is widely used. figure 1 It is a schematic diagram of a typical networking structure of an existing WLAN, such as figure 1 As shown, a WLAN generally includes an access point (AP, Access Pont), an access controller (AC, Access Controller), an authentication authorization and accounting server (AS) and a Dynamic Ho...
