Abstract: PROBLEM TO BE SOLVED: To provide a mobile terminal capable of voice-communicating with a base station in a packet radio service. SOLUTION: The mobile terminal 2 is formed of; a processor 12 which fixes one channel among plural channels for voice communication between the terminal 2 and the base station 22, digitally encodes voice to generate voice information, composes voice information in the form of a voice packet and generates the assigning request of a channel for transmitting the voice packet; a transmitter 8 assigning this channel assigning request and the voice packet to the base station 22 in a network; and a receiver 10 assigned from the base station to receive ID of a channel for transmission of the terminal 2. At the time of receiving channel assignment, the processor 12 checks whether the packet is transmitted by the channel or not.

Abstract: A mobile terminal for communicating with a base station in a packet radio services network. The terminal has a processor for determining one of a plurality of channels for communication between the mobile terminal and the base station; for digitally coding speech to provide speech information; for assembling speech information into speech packets; and for generating channel allocation requests for a channel in which to send speech packets. A radio transmitter is provided for transmitting the requests and the packets to a base station in the network. A radio receiver receives identities of channels allocated by the base station for the mobile terminal to transmit on. The processor is responsive to each received channel allocation to determine that packets are sent on the allocated channel.In the GPRS since a channel is released when there is no packet to transmit, higher traffic levels can be obtained using the same number of radio channels.
