There is an effect that information can be easily provided to the user.

According to the fifth aspect of the present invention, the measurement packet mobile terminal is installed for each wireless area on the wireless area network of the mobile packet communication system.
Since the measurement server is connected to the protocol gateway system of the mobile packet communication system, the quality measurement target is the same communication path as the packet communication when the user actually uses the mobile packet communication service on demand. In addition, the range of the quality measurement can be the range of the equipment of the mobile communication carrier, and it is possible to provide the user with quality information having a clear range of the quality measurement. .

According to the sixth aspect of the present invention, since the measurement server is connected to the protocol gateway system through a line whose quality is sufficiently guaranteed, it is possible to obtain more accurate quality information.

According to the seventh aspect of the present invention, the user service front provides the user with the radio area quality measurement information of the plurality of mobile packet communication systems. There is an effect that the provided quality information can be used when selecting a specific mobile packet communication service from a plurality of mobile packet communication services provided by a plurality of mobile communication carriers.

Claims (7)

(57) [Claims] 1. A measurement packet mobile terminal transmits a measurement packet to a measurement server, stores a transmission time of the measurement packet, activates a measurement response timer, and the measurement server When the measurement packet is received via the mobile packet communication system, a measurement response packet is transmitted to the measurement packet mobile terminal, and the measurement packet mobile terminal is connected via the mobile packet communication system. When receiving the response packet for measurement, stores the reception time of the packet for measurement response, calculates the packet transmission response delay time that is the time difference between the transmission time of the measurement packet and the reception time of the measurement response packet, In addition, when a timeout occurs without receiving the measurement response packet within a timeout period set in advance in the measurement response timer, Quality information measuring method in a mobile packet communication system, characterized by storing the time-out. 2. When transmitting a measurement packet, storing the transmission time of the measurement packet, activating a measurement response timer, and receiving the measurement response packet via the mobile packet communication system, The reception time of the measurement response packet is stored, and a packet transmission response delay time, which is a time difference between the transmission time of the measurement packet and the reception time of the measurement response packet, is calculated. If a timeout occurs without receiving the measurement response packet within the set timeout period, the measurement packet mobile terminal that stores the timeout and the measurement packet transmitted from the measurement packet mobile terminal 70 are transmitted. When received via the mobile packet communication system, the measurement response packet is transferred to the measurement packet Quality information measurement system in a mobile packet communication system characterized in that a measurement server that transmits through the mobile packet communication system to the terminal. 3. The measurement packet mobile terminal transmits the measurement packet to the measurement server, stores the transmission time of the measurement packet, starts a measurement response timer, and the measurement server When the measurement packet is received via the mobile packet communication system, a measurement response packet is transmitted to the measurement packet mobile terminal, and the measurement packet mobile terminal is connected via the mobile packet communication system. When receiving the response packet for measurement, stores the reception time of the packet for measurement response, calculates the packet transmission response delay time that is the time difference between the transmission time of the measurement packet and the reception time of the measurement response packet, In addition, when a timeout occurs without receiving the measurement response packet within a timeout period set in advance in the measurement response timer, The time-out is stored, and the quality measurement result, which is information such as the stored packet transmission response delay time and the presence / absence of the time-out, is provided to a quality measurement management station. The information is stored as wireless area quality measurement information associated with the measured information for each wireless area, and the wireless area quality measurement information is provided to a user service front, and the user service front provides the user with the wireless area quality measurement information. A method for providing quality information in a mobile packet communication system. 4. When transmitting a measurement packet, storing the transmission time of the measurement packet, activating a measurement response timer, and receiving the measurement response packet via the mobile packet communication system. The reception time of the measurement response packet is stored, and a packet transmission response delay time, which is a time difference between the transmission time of the measurement packet and the reception time of the measurement response packet, is calculated. If a timeout occurs without receiving the response packet for measurement within the set timeout time, the timeout is stored, and a quality measurement result that is information such as the stored packet transmission response delay time and the presence or absence of the timeout is transmitted.
