Mobile phone tracking refers to the attaining of the current position of a mobile phone, stationary or moving. Localization may occur either via multilateration of radio signals between (several) radio towers of the network and the phone, or simply via GPS. To locate the phone using multilateration of radio signals, it must emit at least the //roaming// signal to contact the next nearby antenna tower, but the process does not require an active call. GSM is based on the signal strength to nearby antenna masts.

= Online journey planning =

A journey planner is a specialised electronic search engine used to find the best journey between two points by some means of transport. Journey planners have been widely used in the travel industry since the 1970s by booking agents accessed through a user interface on a computer terminal, and to support call centre agents providing public transport information. With the use of the internet, self-service browser based on-line journey planner interfaces for use by the general public have become widely available. A journey planner may be used in conjunction with ticketing and reservation systems, or just to provide schedule information.
