Problems solved by technology

However, the realization of AGPS positioning must pass multiple network transmissions (up to six one-way transmissions), which takes up a lot of air resources
At the same time, the AGPS positioning mobile terminal must be equipped with a GPS receiver, and when the satellite signal cannot be received, such as: indoors, garages, urban high-rise dense areas, positioning cannot be achieved

Embodiment Construction

[0022] Since the basic idea of ​​existing mobile terminal positioning methods is to use GPS positioning technology, there are certain restrictions on applicable locations and mobile terminals. The positioning method based on the telecommunications smart card provided by the embodiment of the present invention can store the corresponding relationship between the base station information and time of the mobile terminal location in the telecommunications smart card, and when the trigger condition of the reported information arrives, the stored base station information and the storage time The corresponding relationship is reported to the positioning server, and the positioning server can locate the mobile terminal according to the received corresponding relationship between base station information and time. By adopting the method of the embodiment of the present invention and the positioning method of the embodiment of the present invention, there is no need to make any improvemen...

Abstract

The invention relates to the field of wireless communication and in particular discloses a telecom smart card, a locating method based on the same, a server and a system. The locating method based on the telecom smart card comprises the following steps of: triggering the telecom smart card under a triggering condition; sending stored base station information and a storage time corresponding to the stored base station information to a locating server by the telecom smart card; and locating a mobile terminal according to the received base station information and the corresponding storage time by the locating server. By utilizing the method, the mobile terminal is unnecessarily modified, any additional operation is not needed to be carried out by a subscriber, and the mobile terminal can be located without bearing much cost.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a positioning method based on a telecommunication smart card, a telecommunication smart card, a server and a system. Background technique [0002] Since its application, GPS positioning technology has attracted many users around the world with its high precision, all-weather, global coverage, convenience and flexibility, and high quality and low price. GPS positioning technology locates the mobile terminal by installing a GPS module on the mobile terminal, and realizes the networking of the mobile terminal through mobile terminal short message or mobile terminal wireless Internet communication, thereby completing the monitoring of the mobile target position. However, GPS technology is a patented military technology of the United States, and its application field is limited. At the same time, GPS positioning is achieved by receiving satellite signals through GPS receivers. GPS rec...
