The present invention provides a system, method and apparatus for providing multiple quality of service classes to subscribers in a network by determining a subscriber's quality of service information by using a database containing quality of service information for each subscriber that has subscribed to one of the multiple quality of service classes, and storing the subscriber's quality of service information in a visitor location register where the subscriber is currently registered.

Method, apparatus and system for providing multiple quality of service classes to subscribers in a network

Permanent virtual channels are set-up, each broadcasting a select audio tone of a number of audio tones. When a terminal requests a call set-up, the identification of the appropriate permanent virtual channel to which the terminal is to listen, depending on the situation, is transmitted to the terminal from the network control center. The tone generating equipment is located in the network control center.

Systems and methods related to maintaining a signaling link between network terminals in a communications network. Periodic receiver ready frames are transmitted from a first terminal to a second terminal when there are no data frames to be transmitted. A temporal period is determined during which a predetermined condition will affect communications with the second terminal; the predetermined condition can be, for example, a period during which the sun will be within a predetermined subtended angle of an antenna associated with the second terminal. The second terminal transmits a pause frame to the first terminal prior to the temporal period; the pause frame includes the identification of the temporal period. The first terminal then pauses the transmission of data frames and the periodic receiver ready frames during the temporal period, and resumes the transmission of data frames and periodic receiver ready frames subsequent to the expiration of the temporal period, whereby it is unnecessary to re-establish a signaling link between the first and second terminals upon the expiration of the temporal period.
