(Mobile communication method)
Next, the mobile communication method by the mobile communication apparatus according to this embodiment configured as described above will be described. 3 and 4 show a flowchart of the mobile communication method according to this embodiment.

  As shown in FIG. 3, in the mobile communication method according to this embodiment, first, in step ST1, calculated travel route data (predicted route) set by the in-vehicle navigation device 10 mounted on the user's vehicle 5 is used. ) And at least current position data, speed data, and communication area data are acquired by the ECU 11 based on the GPS information data received by the GPS receiver 15. Subsequently, the ECU 11 calculates the time required for the user's vehicle 5 to leave the communication area from the current position based on the acquired current position data, speed data, and communication area data. Thereby, communicable time data (expected transit time data) is generated. Thereafter, the communicable time data is supplied from the ECU 11 to the CPU 41 of the information processing unit 40 and temporarily stored in the RAM 43. As the data output from the in-vehicle navigation device 10, any data including communicable time data can be adopted. Specifically, as shown in FIG. The current position of the vehicle, communication area (service area) information, travel route information of the corresponding vehicle 5, and the like are supplied to the information processing unit 40.

  In step ST <b> 2, the congestion rate data at the current position of the vehicle 5 is supplied from the receiver 33 of the transmission / reception unit 30 to the CPU 41 of the information processing unit 40 and temporarily stored in the RAM 43. Note that the processing of step ST2 and step ST1 is not necessarily limited to this order, and the calculation of the communicable time data in step ST1 and the acquisition of the congestion rate data in step ST2 change the execution order. It is also possible to execute at the same time. Then, when the acquisition process of step ST1 and step ST2 is completed, the process proceeds to step ST3.

In step ST3, a transfer amount prediction calculation process is executed by the information processing unit 40 from the communicable time data included in the information data supplied from the in-vehicle navigation device 10 and the congestion rate data supplied from the transmission / reception unit 30. Is done. The transfer amount D obtained by this transfer amount prediction calculation process is at least a function of the possible communication time t.
D = f (t) (1)
It can be expressed as.

Here, the transfer amount prediction calculation process will be described with reference to FIG. As illustrated in FIG. 4, in step S <b> 1, the information processing unit 40 includes various information (current position information, predicted traveling route information, current speed, predicted speed) including the estimated transit time (communication time) from the in-vehicle navigation device 10. , The expected effective bandwidth) is input (see step ST1 in FIG. 3), and various information (expected communication congestion rate, effective bandwidth) is input from the receiver 33 of the transmission / reception unit 30 (FIG. 3,
Step ST2), the information is temporarily stored in the RAM 43 of the information processing unit 40, and the CPU 41 executes arithmetic processing based on these data to calculate the possible transfer amount (Step S2).

Specifically, f (t) in the above equation (1) is
D = f (t) = B · t · C (2)
(B: Effective bandwidth, C: Constant (congestion rate / safety rate))
Then, the predicted transfer amount D is expressed by a linear expression of the effective band B supplied from the in-vehicle navigation device 10 or the transmission / reception unit 30, a constant C, and the possible communication time t, and is calculated by integration processing. The In addition, in order to improve the accuracy, the possible transfer amount may be calculated using information data other than the estimated transit time and the congestion rate supplied from the in-vehicle navigation device 10 or the transmission / reception unit 30 as variables as necessary. It is also possible to use a quadratic or higher formula.

  Thereafter, the process proceeds to step ST4 shown in FIG. 3, and the transfer queue at the current stage is acquired. Specifically, a transfer queue in which the first transfer queue is “movie download”, the second is “music reception”, the third is “mail delivery”, and the fourth is “chat” is acquired. The

  Thereafter, the process proceeds to step ST5, transfer queue adjustment processing is executed, and the transfer queue is optimized. In other words, in step S2 shown in FIG. 4, the transfer queue rank before transfer (transfer data reception rank) is moved in the order of the most efficient transfer based on the predicted transfer amount calculated as described above. Will be changed. Specifically, when the priority of “mail delivery” is high and “movie download” or “music reception” is low as the priority for the acquired transfer queue, “ “Mail delivery” is ranked, and “chat” is ranked second. Further, when the priorities are the same, for example, they are ranked in descending order of transfer amount, or in order of increasing transfer amount. In this embodiment, when ranking is performed in descending order of transfer amount, “movie download” is ranked third, and “music reception” is ranked fourth.

  Thereafter, the process proceeds to step S3, where various parameters (communication scheduled task, required communication amount, importance) are changed based on the changed rank of the transfer queue. The transfer data described above is received. These processes are repeatedly executed as necessary so as to always maintain an optimum state in which transfer data with high importance can be preferentially received.

  As described above, the delivery data changing process according to this embodiment is executed, and information having high importance for the user is based on the information data of the communicable time supplied from the in-vehicle navigation device 10 to the information processing unit 40. Therefore, the transfer data can be received very efficiently.

  The embodiment of the present invention has been specifically described above, but the present invention is not limited to the above-described embodiment, and various modifications based on the technical idea of the present invention are possible.

  For example, the data content of the delivery data distributed in the above embodiment is merely an example, and different data content of the delivery data may be used as necessary.

The present invention can be applied to any terminal capable of optimizing the amount of communication in a mobile body equipped with a communication terminal, and specifically, any terminal represented by a portable terminal, a PDA, a notebook PC, etc. It can be applied to a mobile terminal.
