A location of a mobile terminal in a given area may be determined by including the mobile terminal in a satellite-based positioning system and in a cellular communications system. The approximate coordinates of the mobile terminal may be determined based on both satellite signals received from the satellite-based system and information related to the cellular communication system, where the coordinates include an altitude coordinate. An estimate of the altitude coordinate may be derived from the information related to the cellular communication system. The approximate coordinates may be determined using the estimate of the altitude coordinate and information provided by the satellite-based system by providing an approximate bi-dimensional positioning of the terminal and exploiting the bi-dimensional positioning and the estimate of the altitude coordinate.

Method for the location of mobile terminals

A method for enabling a subscriber terminal to remotely access terminal equipment, the terminal equipment storing identification data of the subscriber terminal, and the subscriber terminal being subscribed to a communication network and to a remote access service, wherein the method includes: receiving a request for authentication from the terminal equipment, the request for authentication including identification data of the subscriber terminal; receiving a request for access to the terminal equipment from the subscriber terminal; authenticating the subscriber terminal based on information from the communications network; forwarding the request for authentication from the terminal equipment to the subscriber terminal upon authenticating the subscriber terminal, the subscriber terminal processing the request for authentication to authenticate the terminal equipment; receiving an authentication notification from the subscriber terminal; forwarding the authentication notification from the subscriber terminal to the terminal equipment, the terminal equipment processing the authentication notification to authenticate said subscriber terminal; receiving an authentication notification from the terminal equipment; and enabling the subscriber terminal to remotely access the terminal equipment upon receiving the authentication notification from the terminal equipment.

Hybrid locating method and system for locating a mobile terminal in a wireless communications network

The location of a mobile terminal in a given area is determined by including the mobile terminal both in a satellite-based positioning system and in a cellular communications system. The mobile terminal is thus adapted to receive satellite signals from the satellite-based system and to be covered by at least one cell of the cellular communications system. The mobile terminal is configured for determining at least approximately its coordinates, including an altitude coordinate in the area, based on both satellite signals received from the satellite-based system and information related to the cellular communications system. An estimate of the altitude coordinate is derived from the information related to the cellular communications system, whereby satisfactory location performance is ensured also when one or more satellites in the satellite-based system are not visible at the mobile terminal.
