Abstract

A method for saving battery power in a wireless telephone which receives mode information from a base station in which information on a first mode where only a voice channel is searched, information on a second mode where a voice channel and a data channel are alternately searched while changing a search period of the data channel, and information on a third mode where a voice channel and a data channel are alternately searched at stated periods are registered. The method comprises searching mode information transmitted from the base station; searching a voice channel upon receiving first mode information from the base station; alternately searching a voice channel and a data channel while changing a search period of the data channel, upon receiving second mode information from the base station; and alternately searching the voice channel and the data channel at stated periods, upon receiving third mode information from the base station.

Claims

1. A method for saving power of a battery in a wireless telephone, comprising the steps of:

searching a voice channel in a standby state; and

accessing data upon receiving a data request in the standby state in which the voice channel is searched.

2. The method of claim 1, wherein a call is performed if a voice signal is transmitted in the standby state.

3. The method of claim 1, further comprising the steps of:

searching a voice channel after the data access;

performing a call if a vice signal is transmitted in a data access state where the voice channel is searched; and

performing the data access when the call is ended.

4. A method for saving power of a battery in a wireless telephone, comprising the steps of:

registering a voice signal and a data signal;

alternately searching a voice channel and a data channel;

increasing a search period of the data channel if a data signal is received within a predetermined search period in the data channel searching step; and

decreasing the search period of the data channel if no data signal is received within the predetermined search period in the data channel searching step.

5. The method of claim 4, wherein the search period of the data channel is automatically increased or decreased.

6. The method of claim 4, wherein the search period of the data channel is increased or decreased by a predetermined value.

7. A method for saving battery power in a wireless telephone which receives mode information from a base station in which the mode information comprising information on a first mode where only a voice channel is searched, information on a second mode where a voice channel and a data channel are alternately searched while changing a search period of the data channel, and information on a third mode where a voice channel and a data channel are alternately searched at stated periods are registered, the method comprising the steps of:

(a) searching mode information transmitted from the base station;

(b) searching a voice channel upon receiving first mode information from the base station;

(c) alternately searching a voice channel and a data channel while changing a search period of the data channel, upon receiving second mode information from the base station; and

(d) alternately searching the voice channel and the data channel at stated periods, upon receiving third mode information from the base station.

8. The method of claim 7, wherein the step (b) comprises the steps of:

searching a voice channel in the standby state; and

accessing data upon receiving a data request in a standby state where only the voice channel is searched.

9. The method of claim 7, wherein the step (c) comprises the step of:

registering a voice signal and a data signal;

alternately searching a voice channel and a data channel;

increasing a search period of the data channel if a data signal is received within a predetermined search period in the data channel searching step; and

decreasing the search period of the data channel if no data signal is received within the predetermined search period in the data channel searching step.
