ABSTRACT:
Methods and apparatus are disclosed for operating a cellular communication network. An exemplary method includes the steps of transmitting a message from a base station (30) to a mobile station (10) located within a cell served by the base station, the message including location information for specifying a geographical location of the base station; storing the location information in the mobile station; originating a predetermined call type with the mobile station and appending the stored location information to a call origination message; and routing the call from the network to the call's destination in conjunction with the appended location information. The location information includes at least one of a latitude and a longitude at which the base station is located and an alphanumeric string that is expressive of a geographical location at which the base station is located. The base station location information is useful in determining a location of the mobile station, such as when an emergency call is made. In a further embodiment of this invention an emergency call is originated by a mobile station in response to the deployment of an air bag in a vehicle wherein the mobile station is located.
