Embodiment Construction

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0041] The invention proposes a low-precision positioning service method realized in the packet data domain of the mobile communication network. It also includes a relatively complete location service development process and network entity architecture. The method utilizes the cell information managed by the mobile terminal to realize the location service with low precision, but the service development is convenient and the cost is low.

[0042] A mobile terminal in a mobile communication network has several states of CELL_DCH, CELL_FACH, CELL_PCH, and URA_PCH at the RRC (Radio Resource Control, radio resource control) level. For example, in the UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) network, when th...

Abstract

The invention provides a locating method of a mobile terminal and a mobile location center, used for realizing location of the mobile terminal in a packet data field; the method comprises the following steps: step1, the mobile location center and a wireless network controller carry out synchronization of base station data; step 2, an application program module of the mobile terminal updates cell set information and transmits the cell set information to the mobile location center through a gateway general packet radio service support node GGSN element location in the packet data field; step 3, the mobile location center calculates location information of the mobile terminal according to the cell set information and the base station data. The invention does not relate to a control field element location of a mobile communication network, thus facilitating the location service to be conveniently developed with lower cost and solving the technical problems of high cost of the prior art and great influence on the existing network.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a mobile terminal positioning method and a mobile positioning center in a mobile communication network. Background technique [0002] LBS (Location Based Service, location-based service) is also known as mobile location service or positioning service (hereinafter collectively referred to as positioning service), which refers to the interaction between the mobile positioning center and some entities in the mobile communication network, and then through wireless Positioning technology or assisted GPS (Global Positioning System, Global Positioning System) positioning technology obtains the necessary measurement data of the mobile terminal, and then completes the estimation of geographical location information such as longitude and latitude coordinates through the position calculation entity, and provides corresponding call or non-call based on the position of the mobile terminal. bus...
