Abstract
The invention relates to a wireless telecommunication system for voice and data packet transmission. The system comprises a transmitting unit for transmitting voice and data packets to a receiving unit. The transmitting unit comprises a first discard timer set for a first time period and arranged to start when a first data packet is transmitted from the transmitting unit. The transmitting unit is arranged to suspend the first discard timer when a second power is lower than or equal to a selected second threshold level.
Claims24
A wireless telecommunication system for voice and data packet transmission, the system comprising:
- a transmitting unit for transmitting voice and data packets to a receiving unit, the transmitting unit having a maximum power and being arranged to transmit high priority data on a first dedicated channel with a first power being of a magnitude within a first range ranging from zero to the difference between the maximum power and a selected first threshold level and low priority data on a second dedicated channel with a second power being of a magnitude within a second range ranging from zero to the difference between the maximum power minus the first power minus the first threshold level,
- the transmitting unit further comprising a first discard timer set for a first time period and arranged to start when a first data packet is transmitted from the transmitting unit, the transmitting unit being arranged to discard the first data packet if it has not been acknowledged by the receiving unit within the first time period or after a predetermined number of retransmissions of the first data packet, the transmitting unit being arranged to suspend the first discard timer when the second power is lower than or equal to a selected second threshold level.
A method for a wireless telecommunication system for voice and data packet transmission, comprising:
- transmitting voice and data packets from a transmitting unit to a receiving unit, wherein the transmitting unit has a maximum power and transmits high priority data on a first dedicated channel (DCH) with a first power being of a magnitude within a first range ranging from zero to the difference between the maximum power and a selected first threshold level and transmits low priority data on a second dedicated channel with a second power being of a magnitude within a second range ranging from zero to the difference between the maximum power minus the first power minus the first threshold level;
- setting a first discard timer in said transmitting unit for a first time period and starting it when a first data packet is transmitted from the transmitting unit;
- discarding the first data packet if it has not been acknowledged by the receiving unit within the first time period or after a predetermined number of retransmissions of the first data packet;
- and
- suspending the first discard timer when the second power is lower than or equal to a selected second threshold level.
