A system enabling the dissemination of location data between user terminals and to and from network resources, and the utilization of the location data in a manner convenient to users. User terminals, such as cellular telephones, personal digital assistants (PDAs), personal computers, and other interactive devices, may be location-enabled or conventional user terminals capable of transmitting service request data to network resources. In the case of location-enabled terminals, the terminal may store a plurality of items of location data, including spatial coordinate data, for dissemination to other user terminals and/or for transmission to network resources. The items of location data may be derived from systems for sensing the location of the mobile terminal, including satellite base positioning systems such as the global positioning system (GPS) or network-based or assisted positioning systems. Other sources of location data include other user terminals, network resources or manual provisioning of location data by the user at the terminal. In an alternative embodiment, user-selected location data is stored in a network-side store for use by the user in relation to a range of remote processes, and is made accessible to a range of other network resources or users. Items from the network-side store may transmitted to others for use in relation to service requests and other processes.
