Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The information of its current network can usually be stored in a mobile communication terminal, such as LAC (location area code, location area code), Cell-ID ((Cell Identifier, cell identification code), etc., wherein CellID is a cell identification code, which is used to identify mobile The cell of the network where the communication terminal is currently located is usually a series of numbers. Correspondingly, the mobile operator usually has a corresponding database to store the Cell ID and corresponding location information of each cell.

Abstract

The invention is suitable for a mobile communication terminal, and provides a method for acquiring position information by the mobile communication terminal. The method comprises the steps of: a, sending a USSD (Unstructured Supplementary Service Data) location request to a mobile operator server by the mobile communication terminal, wherein the USSD location request carries a Cell-ID of a cell in which the mobile communication terminal is located; and b, receiving the feedback information of the mobile operator server by the mobile communication terminal, wherein the information carries the position information corresponding to the Cell-ID. Compared with the traditional GPS location mode, the technical scheme provided by the invention has simpler and more rapid realization, no need of complex operation and no need of extra support from software and hardware.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method for a mobile communication terminal to acquire location information. Background technique [0002] USSD (unstructured supplementary service data, unstructured supplementary data service), defined as a mechanism for transmitting information and instructions between the mobile station and the network application through the home location register (HLR), it provides a text-based interface for mobile communication users , to manage the user's business. For example, the user can enter "*#SC*n characters#" in the dial interface and press the Send button to send the request to the network, where "SC" is the service code, and "n characters" are other characters required by the request. Code, can be empty. For example "*21*1234567#" might mean requesting the network to forward all calls to the number 1234567. [0003] With the development of mobile com...
