[0002] GSM (General System for Mobile Communications) has been widely used all over the world. The base stations of the cellular network in the GSM system generally have a large and expensive structure, with a height of tens of meters and a service area radius of tens of kilometers; traditional cellular The voice quality of network communication is generally very low (8 kbit / s to 13 kbit / s); traditional cellular network communication is also limited by the amount of traffic that can be carried. When the number of users increases, the system becomes very crowded

Embodiment Construction
[0033] The process of the present invention to provide location services for users is as follows:
[0034] 1) User registration, as well as canceling users, changing passwords, etc.;
[0035] 2) The user initiates a location service request;
[0036] 3) The system locates the located user according to the user location service request;
[0037] 4) The system obtains the user's current location information (latitude and longitude), and sends the location and service request to the map application server;
[0038] 5) After the map application server obtains the service result, it returns the result to the system and sends it to the user terminal.
[0039] In order to realize the complete location service in the PHS system, a complete location service system is required. The location service system in the present invention includes a location service gateway, a positioning server and an application server, wherein the location service gateway is connected to the existing PHS n...

The invention is a position service implementing system and method in wireless local telephone short message mode, including a position service gateway, a positioning server and an application server, which are interconnected. The position service gateway is connected with the existing wireless local telephone network. The positioning server and position service gateway complete a user positioning function; the application server implements a control from application request to application result return, content provision, and other functions, and can take a map server. The method includes: the user initiates a request for position service by short messages; the position service system completes positioning the user; the system sends the service result to the user. It is convenient for use, easy to upgrade, needs low real-time, and has good extendability. It needs lower real-time property and reduces the requirement for positioning time.
Description
technical field [0001] The invention relates to the location service in the wireless local telephone (PHS) system, especially the system and method for realizing the location service by short message. Background technique [0002] GSM (General System for Mobile Communications) has been widely used all over the world. The base station of the cellular network in the GSM system generally has a large and expensive structure, with a height of tens of meters and a service area radius of tens of kilometers; traditional cellular The voice quality of network communication is generally very low (8 kbit / s to 13 kbit / s); traditional cellular network communication is also limited by the amount of traffic that can be carried. When the number of users increases, the system becomes very crowded. A new wireless communication standard has developed rapidly in recent years, that is, the microcellular standard for wireless communication in the frequency band around 1990MHz, including: PACS (Per...
