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.

Claims

1. 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.

2. The method of claim 1, wherein transmission of the second information at the second data rate does not occur until after the cellular base station is configured to transmit the second information.

3. 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.

4. The subscriber unit of claim 3, wherein transmission of the second information at the second data rate does not occur until after the cellular base station is configured to transmit the second information.

5. 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.

6. The method of claim 5, wherein transmission of the second information at the second data rate does not occur until after the base station is configured to transmit the second information.

7. A base station comprising:

circuitry configured to transmit a first signal, to the subscriber unit, including first information at a first data rate;

circuitry configured to receive a second signal from the subscriber unit;

circuitry configured to transmit 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

circuitry configured to transmit 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.

8. The base station of claim 7, wherein the transmission of the second information at the second data rate does not occur until after the base station is configured to transmit the second information.
