MOBILE COMMUNICATION DEVICE AND COMMUNICATION CONTROL METHOD
Provided are a mobile communication device and communication control method for imposing a limitation so that, under a situation in which transmission and/or reception of information to and/or from another communication device is unnecessary, the transmission and/or reception of the information to and/or from the another communication device is not carried out to avoid unnecessary transmission/reception of the information, to thereby reduce a power consumption. The mobile communication device, which is provided in a mobile object, includes: a movement detection sensor for detecting movement of the mobile object; a communication unit for communicating to/from another communication device; and a control unit for determining whether the mobile object is moving or not based on an output of the movement detection sensor, in which the control unit transmits and/or receives information to and/or from the another communication device through the communication unit only when determining that the mobile object is moving.
1 . A mobile communication device, which is provided in a mobile object, comprising:
a movement detection sensor for detecting movement of the mobile object;
a communication unit for communicating to/from another communication device; and
a control unit for determining whether the mobile object is moving or not based on an output of the movement detection sensor,
wherein the control unit transmits and/or receives information to and/or from the another communication device through the communication unit only when determining that the mobile object is moving.
2 . A mobile communication device according to claim 1 , wherein the control unit further determines whether a current position of the mobile object is near an intersection or not, and transmits and/or receives the information to and/or from the another communication device through the communication unit only when the mobile object is moving and the current position of the mobile object is near the intersection.
3 . A mobile communication device according to claim 1 ,
wherein the mobile object comprises a pedestrian, and
the control unit determines whether the pedestrian rides in a vehicle or not, and avoids the transmission and/or reception of the information to and/or from the another communication device through the communication unit irrespective of whether the pedestrian is moving or not when the pedestrian rides in the vehicle.
4 . A mobile communication device according to claim 1 ,
wherein the mobile object comprises a pedestrian, and
the control unit determines whether the pedestrian is operating the mobile communication device or not, and avoids the transmission and/or reception of the information to and/or from the another communication device through the communication unit irrespective of whether the pedestrian is moving or not when the pedestrian is not operating the mobile communication device.
5 . A mobile communication device according to claim 1 , wherein the control unit gives, through a notification unit, a notification that there is a risk that the mobile object collides with another mobile object including the another communication device based on the information acquired from the another communication device through the communication unit.
6 . A mobile communication device according to claim 1 ,
wherein the mobile object comprises a pedestrian, and
the control unit determines whether the another mobile object is the pedestrian or not, and avoids giving a notification that there is a risk that the mobile object collides with the another mobile object when the another mobile object is the pedestrian.
7 . A mobile communication device according to claim 1 , wherein the control unit stops feeding power to the communication unit, to thereby avoid the transmission and reception of the information to and from the another communication device through the communication unit.
8 . A communication control method, comprising the steps of:
determining whether a mobile object is moving or not based on an output of a movement detection sensor for detecting movement of the mobile object; and
transmitting and/or receiving information to and/or from another communication device through a communication unit only when the mobile object is moving.
