Abstract
A subscriber unit, used for communicating in voiced communications at a first data rate and communicating at a second data rate for other data, suppresses a selected communication during communication rate modification. A determination is made as to whether the transmission requires a change in data rate, and a switching circuit responds by engaging a different communication channel. Blocking circuitry blocks transmissions until the different data rate is established. This provides an optimum data rate, while preserving the integrity of the data transmitted.
Claims8
A method for use in a subscriber unit, the method comprising:
- receiving first information at a first data rate from a cellular base station;
- determining, in response to a first signal received from the cellular base station, whether to receive second information at a second data rate different than the first data rate from the cellular base station;
- transmitting a second signal to the cellular base station;
- receiving a third signal from the cellular base station, wherein the third signal carries an acknowledgement indicative of a configuration of the cellular base station to transmit the second information at the second data rate;
- and
- receiving the second information at the second data rate from the cellular base station, wherein the first information is carried by a first modulated signal having a first modulation type and the second information is carried by a second modulated signal having a second modulation type.
3 more elements
A subscriber unit comprising:
- an input configured to receive first information at a first data rate from a cellular base station;
- a circuit coupled to the input and configured to receive the first information, the circuit also being configured to determine whether to receive second information at a second data rate different than the first data rate from the cellular base station;
- an output coupled to the circuit, such that, in response to a first signal received from the cellular base station, the output supplies a second signal to the cellular base station;
- wherein the input is further configured to receive a third signal from the cellular base station, wherein the third signal carries an acknowledgement indicative of a configuration of the cellular base station to transmit the second information at the second data rate, wherein the first information is carried by a first modulated signal having a first modulation type and the second information is carried by a second modulated signal having a second modulation type.

A method for use in a base station, the method comprising:
- transmitting a first signal, to the subscriber unit, including first information at a first data rate;
- receiving a second signal from the subscriber unit;
- transmitting a third signal to the subscriber unit, wherein the third signal carries an acknowledgement indicative of a configuration of the base station to transmit second information at a second data rate;
- and
- transmitting the second information at the second data rate to the subscriber unit, wherein the first information is carried by a first modulated signal having a first modulation type and the second information is carried by a second modulated signal having a second modulation type;
- wherein the transmitted second information at the second data rate is different than the first data rate.
3 more elements
A base station comprising:
