ABSTRACT:
A wireless cellular voice system and a wireless packet data system cover a common service area consisting of a plurality of cells, and share RF spectrum in providing their respective services to: AMPS phones, CDPD handheld data terminals, and combined AMPS-CDPD subscriber sets. Control of AMPS wireless communication and switching is vested in an AT&T 5ESS.TM. switch and an AT&T 3B20.TM. Access Manager. Control of CDPD communication is vested in a Sun SPARC Data Network Processor operating under standard CDPD protocol. A high speed bus of the Access Manager is extended to the SPARC processor to facilitate coordination of use of the shared wireless channels; and to allow the AMPS facility to originate data messages to combined AMPS-CDPD subscriber sets to implement AMPS data features, e.g., VOICE MESSAGE WAITING; ELECTRONIC MAIL NOTIFICATION; PAGING; and CALLER ID (CID); CALLER ID CALL WAITING (CID-CW).
