Abstract

A dual transfer mode communications network (100), such as a GSM network using AMR and GPRS data transmission modes, allows enhanced data utilization efficiency by multiplexing AMR pauses generated during speech frame transmission by a first mobile system (101) with short packet-switched data bursts from a second mobile system (105). The communications network (100) processes an access request burst signal on an uplink channel from the first mobile system (101) along with the short packet-switched data bursts from the second mobile system (105).
