User defined or entered text messages are transported from a mobile station to the serving mobile switching center (MSC) over a connection-less communications link. An application module within the serving MSC extracts the encapsulated user defined text messages from the received signal for forwarding to the associated billing center. The billing center, after consolidating the call data received by a Toll Ticket, produces billing statements containing the user defined text messages allowing mobile subscribers to better identify and keep record of each call. |
