    Abstract: The wireless system includes one or more payphones (12) from which users may initiate payphone calls. A mobile switching center (16) connects telephone calls initiated from wireless payphones to external telephone systems (18) such as the publlic switch telephone network (PSTN). To meter charges incurred during the telephone call within an external system, the external system transmits periodic metering pulses (52, 54) to the mobile switching center. Each pulse is representative of a predetermined amount of money associated with the telephone call. The rate at which the periodic pulses are transmitted to the mobile switching center depends upon the current billing rate and may be affected by, for example, the time of day. Rather than the forwarding all of the metering pulses to the wireless payphone, therefore consuming a portion of the bandwidth available for wireless telephone calls, the mobile switching center (16) calculates a steady state billing rate from the metering pulses, then transmits only the steady state billing rate to the wireless payphone (12).

    Abstract: A method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller determines if sufficient network resources are available to conduct a inter-system soft handoff. If so, the base station controller generates a set of signaling messages that cause call processing resource to be allocated and for the call to be processed at the second cellular system. The base station controller then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit by way of the second cellular system as well as via one or more base stations to which the base station controller is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

    Abstract: A method of invoking and canceling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.

    Abstract: An apparatus and method of providing communications between standard unmodified terminal equipment over a telephone link that includes a digital wireless link. The digital wireless link introduces substantial time variable delay. In order to pass time sensitive messages over the link, time sensitive messages are recognized and translated into time insensitive messages for transmission over the wireless link. The time insensitive messages indicate the information contained in the time sensitive messages and in the timing of the time sensitive messages. At the receiving end, the time insensitive messages are recognized and the time sensitive messages reconstructed with the appropriate timing.
