ABSTRACT:
A method and apparatus resolves conflicts and ambiguities of GSM standards arising in DTM by monitoring only selected downlink timeslots for uplink status flags (USFs). Downlink timeslots with a packet data channel (PDCH) are monitored for a USF from a lowest numbered time slot, B(0), to a maximum time slot B(MAX) where B(MAX) is equal to the lowest transmission uplink timeslot, B(x), in the corresponding TDMA uplink frame if the second lowest transmission uplink timeslot B(x)+1, is a circuit switched timeslot and where B(MAX) is equal to the second lowest transmission timeslot in the corresponding TDMA frame, B(x)+1, otherwise.
