Mobile radio equipment and method of controlling transmission rate for mobile radio equipment
View Patent ↗Mobile radio equipment and a transmission rate controlling method thereof for reducing the rate of transmission between the mobile radio equipment and a base station when the transmission rate is beyond the capability of the application function of the mobile radio equipment to thereby use the resources of the radio base station effectively. A radio transmitter/receiver receives data or radio signals via an antenna. A transmission system function CPU converts or customizes the data to a data format acceptable to an application function CPU. Subsequently, the transmission system function CPU inputs the data via a data input/output section into a data input/output section of the application function CPU. A decoder 16 is fed with the data input to the data input/output section. After that, the data is decoded by the decoder, and output from an input/output section according to the format of the decoded data.
1. Mobile radio equipment, comprising:
a radio transmitter/receiver for transmitting/receiving radio data;
a transmission unit for converting the received data received by the radio transmitter/receiver;
an application unit for executing applications;
a decoder for decoding the data output from the transmission unit;
a memory for storing the decoded data output from the decoder;
an input/output section for inputting/outputting the decoded data output from the decoder;
a load data output section for outputting the decoded data output from the decoder as load data;
a load data input section for inputting the decoded data output from the decoder as load data;
a judge section for judging the load data on a preset threshold value; and
a transmission controller for controlling a transmission rate based on a judgment made by the judge section,
wherein the judge section is provided with two threshold values, one for judging whether the load data is beyond a decoding capability of the decoder, and the other for judging whether the load data is beneath the decoding capability,
wherein the judge section includes a comparator for comparing the load data input from the decoder with the threshold values in order to judge whether an amount of the data is within a capacity of the mobile radio equipment to process,
wherein the transmission controller requests a base station to reduce the data transmission rate when the load data exceeds one of the threshold values, and
wherein the transmission controller requests the base station to increase the data transmission rate when the load data is below the other threshold value.
