Mobile communication terminal device, QoS control device, mobile communication system, and method of guaranteeing QoS

1. A mobile communication terminal device, comprising:

an operation unit registering information related to a predetermined region in which a user desires QoS (Quality of Service) guarantee;

a sending unit sending the information related to the predetermined region registered in the operation unit and information that identifies a current position of the mobile communication terminal device;

a receiving unit receiving QoS guaranteed data when the current position is in the predetermined region; and

a control unit controlling a behavior of sending the information in the sending unit and a behavior of receiving the QoS guaranteed data in the receiving unit.

2. The mobile communication terminal device according to claim 1 , wherein the sending unit sends information that identifies the current position is positional information that is registered in a home location register.

3. The mobile communication terminal device according to claim 1 , further comprising a positional information acquisition unit acquiring information on the current position from a global positioning system:

wherein the information which identifies the current position is the information acquired in the positional information acquisition unit.

4. A QoS (Quality of Service) control device, comprising:

a receiving unit receiving information related to a predetermined region in which a user desires QoS guarantee and information that identifies a current position of a mobile communication terminal device, which are sent from a mobile communication terminal device;

a storage unit storing the information related to the predetermined region received at the receiving unit;

a determination unit comparing the information which identifies the current position of the mobile communication terminal device with the information related to the predetermined region stored in the storage unit; and

a sending unit sending QoS guaranteed data to the mobile communication terminal device when the current position of the mobile communication terminal device is in the predetermined region according to a result of the comparison in the determination unit.

5. A mobile communication system, comprising:

a mobile communication terminal device having an operation unit registering information related to a predetermined region in which a user desires QoS (Quality of Service) guarantee, a positional information sending unit sending the information related to the predetermined region registered in the operation unit and information that identifies a current position of the mobile communication terminal device, a receiving unit receiving QoS guaranteed data when the current position is in the predetermined region, and a control unit controlling a behavior of sending the information in the sending unit and a behavior of guaranteeing the QoS in the receiving unit; and

a QoS control device having a storage unit storing the information on the predetermined region in which the user desires the QoS guarantee, which is sent from the positional information sending unit of the mobile communication terminal device, a determination unit comparing the information which identifies the current position of the mobile communication terminal device, which is sent from the positional information sending unit, with the information related to the predetermined region stored in the storage unit, and a QoS sending unit sending the QoS guaranteed data to the mobile communication terminal device when the current position of the mobile communication terminal device is in the predetermined region according to the result of the comparison in the determination unit.

6. A method of guaranteeing QoS (Quality of Service), comprising the steps of:

sending information related to a predetermined region in which a user desires QoS guarantee from a mobile communication terminal device to a QoS control device;

sending information that identifies a current position of the mobile communication terminal device directly or indirectly from the mobile communication terminal device to the QoS control device;

comparing the acquired information which identifies the current position of the mobile communication terminal device with the information related to the predetermined region in the QoS control device; and

sending QoS guaranteed data to the mobile communication terminal device when the current position of the mobile communication terminal device is in the predetermined region as the result of the comparison.
