Abstract
An apparatus and a method for reducing power consumption in a portable terminal that transmits digital broadcast data through an ad hoc network are provided. If a terminal receiving digital broadcast transmits the received digital broadcast to a neighboring terminal, a control unit enters a sleep mode after buffering received data for a predefined time.
Claims20
An apparatus comprising:
- a memory;
- an antenna;
- a communication unit operatively coupled with the antenna and adapted to transmit a signal to an external electronic device using the antenna;
- and
- a control unit operatively coupled with the communication unit, the control unit adapted to:
- operate in a first state during a first portion of a specified period of time, the operating in the first state including transmitting, using the communication unit, at least one portion of data stored in the memory to the external electronic device during the first portion of the specified period of time, and
- operate in a second state during a second portion of the specified period of time in response to elapsing the first portion, the operating in the second state including transmitting, using the communication unit, time information indicative of a length of the specified period of time to the external electronic device during a first subportion of the second portion of the specified period of time and suspending from transmitting a portion of the data to the external electronic device during the second portion of the specified period of time.

An apparatus comprising:
- a memory;
- an antenna;
- a communication unit operatively coupled with the antenna and adapted to transmit a signal to an external electronic device using the antenna;
- and
- a control unit operatively coupled with the communication unit, the control unit adapted to:
- operate in a first state during a first portion of a specified period of time period, the operating in the first state including transmitting, using the communication unit, at least one portion of data stored in the memory to the external electronic device during the first portion of the specified period of time, and
- operate in a second state during a second portion of the specified period of time in response to elapsing the first portion, the operating in the second state including:
- suspending from transmitting a portion of the data during the second portion of the specified period of time,
- transmitting, using the communication unit, a beacon including time information to be used for communication between the apparatus and the external electronic device to the external electronic device during a first subportion of the second portion of the specified period of time, and
- operating in a sleep state during a second subportion of the second portion after the elapse of the first subportion.
