Abstract
To provide a mobile terminal controlling suitably whether or not a diversity reception should be performed to realize low power consumption, and a data reception method for the same, wherein a mobile phone, when performing a data communication from a server apparatus via a communication network and a base station, decides a necessary and sufficient data rate ODR0 based on a transfer data including an amount of data received and downloaded from the base station and a pilot strength Ec/Io to be an index of a reception status, and judges whether or not the diversity reception should be performed based on a comparison result between the ODR0 and DRC which is the maximum data rate receivable at error rate less than a predetermined value.
Claims14
A mobile terminal comprising:
- a plurality of reception systems;
- a first calculating unit for calculating a reception status data based on reception signals received through the plurality of reception systems;
- a second calculating unit for calculating a first data rate as a predicted data rate based on the reception status data;
- and
- a reception controlling unit for controlling whether or not a diversity reception should be performed based on the reception signals,
- wherein the reception controlling unit does not perform the diversity reception when the first data rate reaches a predetermined second data rate.
A data reception method for a mobile terminal having a plurality of reception systems to perform a diversity reception, said method comprising the steps of:
- calculating a reception status data based on a reception signal;
- calculating a first data rate as a predicted data rate based on the reception status data;
- judging whether or not the first data rate reaches the second data rate;
- requesting a network for data transmission at the second data rate without the diversity reception when the first data rate reaches the second data rate;
- and
- receiving the data from the network.
A program for a mobile terminal having a plurality of reception systems to perform a diversity reception, the program that causes the computer to execute the steps of:
- calculating a reception status data based on a reception signal;
- calculating a first data rate as a predicted data rate based on the reception status data;
- judging whether or not the first data rate reaches the second data rate;
- requesting a network for data transmission at the second data rate without the diversity reception when the first data rate reaches the second data rate;
- and
- receiving the data from the network.
