GEOGRAPHICAL INFORMATION FOR LOCATION-BASED SERVICES

摘要

A method of providing subscriber location information to a radio telecommunication network (10) and an integrated communication network which integrates the radio telecommunication network with at least one wireline communication network. When a subscriber utilizes a mobile station (11) to access the radio telecommunication network, a radio base station (RBS) (13) sends to a mobile switching center (MSC) (15), a cell identity of the cell (12) in which the registration is received from the mobile station. The cell identity is converted in a cell/coordinate (25) table to a range of geographic coordinates that approximate the coverage area of the cell. The geographic coordinates are then sent from the MSC to the radio telecommunication network or to a gateway (23) for the integrated communication network in a network access message. The coordinates may replace or supplement cell-related information in the network access message.
