Abstract
Communication devices, methods, and computer program products acquire a first time division multiple access (TDMA) time slot on a TDMA carrier frequency to establish a first call and acquire a second TDMA time slot on the TDMA carrier frequency to establish a second call. The first and second time slots are associated with a single TDMA frame, which may allow, for example, a voice call and a data call to be established concurrently. Accordingly, the need for multiple phones to maintain both a voice connection and an Internet connection concurrently on a TDMA network may be obviated. Inasmuch as the two time slots are on the same TDMA carrier frequency, additional frequency synthesizers or tuning of existing frequency synthesizers may not be required.
