[0039] Figure 4 It is a functional block diagram showing the processing functions of the mobile communication terminal PS, the base station CS, and the control device 4 according to the first embodiment of the present invention. exist Figure 4 Among them, the mobile communication terminal PS includes a call connection processing unit P1, a base station selection unit P2, and a handover control unit P3. The base station CS includes a call connection processing unit C1, a handover control unit C2, a remaining resource management unit C3, a remaining resource notification unit C4, and a handover instruction sending and receiving unit C5. The control device 4 includes a call connection processing unit 41 , a surplus resource receiving unit 42 , and a handover instruction unit 43 .
[0040] Among them, the call connection processing units P1, C1, and 41 respectively set up a call between the mobile communication terminal PS and the other party through a known call connection pr...
no. 2 Embodiment approach
[0063] Figure 9 It is a functional block diagram showing the processing functions of the mobile communication terminal PS, the base station CS, and the control device 4 according to the second embodiment of the present invention. exist Figure 9 in, for with Figure 4 Common parts are assigned the same reference numerals, and only different parts will be described here.
[0064] exist Figure 9 Among them, the control device 4 includes a resource management table 44 . Such as Figure 10 As shown, the resource management table 44 is a table used to associate and manage each base station with the number of its remaining resources. That is, in this embodiment, the remaining resource notification unit C4 of each base station CS notifies the control device 4 of its own remaining resource number, for example, periodically or in response to an inquiry from the control device 4 . That is, regardless of whether the number of remaining resources is equal to or less than a predete...
no. 3 Embodiment approach
[0073] Figure 13 It is a functional block diagram showing the processing functions of the mobile communication terminal PS, the base station CS, and the control device 4 according to the third embodiment of the present invention. exist Figure 13 in, for with Figure 4 , Figure 9 Common parts are denoted by the same reference numerals, and only different parts will be described here.
[0074] exist Figure 13 Among them, the mobile communication terminal PS includes a detected base station information transmitter P4. The detected base station information transmitter P4 notifies the control device 4 of the identification information of the base station that captured the radio wave via the base station being connected. For example, Figure 8 The mobile communication terminal PS4 is connected to the base station CS3 and is in the wireless zone of CS4, and receives radio waves from both base stations. In this embodiment, these base stations capable of capturing radio wave...
