Problems solved by technology

However, in the technology of this document, there is still a possibility that the processing will not catch up with the control to eliminate the busy resources from the time when the handover request is generated.
[0007] In the conventional mobile communication system, handover may not be possible due to insufficient resources of the handover destination base station, which becomes a hindrance in improving the high-speed mobility performance of the mobile communication terminal

[0036] 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 .

[0037] 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...

[0060] 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.

[0061] exist Figure 9 Among them, the control device 4 includes a resource management table 44 . Such as Figure 10As 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 predeter...

[0070] 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.

[0071] 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. E.g, 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 waves are re...

Abstract

The invention provides a mobile communication system, a control device and a base station device thereof, wherein the base station (CS) sends a situation that the left resource amount is below a determined value (such as 0) to the control device (4); the control device (4) received the situation answers the base station and returns a transferring indication message to the base station (CS) of a notifying resource; the base station (CS) received the message indicates a connected mobile communication terminal (PS) to transfer to other base stations; the mobile communication terminal (PS) received the indication message transfers to the highest level in other multiple base stations receiving electric waves. Thus, the elimination of a busy resource of a transferring destination is capable of improving the high-speed mobility property of the mobile communication terminal.

Description

technical field [0001] The present invention relates to, for example, a mobile communication system in which an area is formed by a microcell, and particularly relates to a technique related to a so-called handover (also referred to as handover) of base station switching accompanying movement of a mobile communication terminal. Background technique [0002] There are generally macro-cell and micro-cell systems in mobile communication systems for forming areas. The former is typically a so-called mobile phone system, and the radius of each wireless area reaches several kilometers. On the other hand, for example, PHS (Personal Handy-phone System (personal mobile phone system)) adopts the latter method, and the area radius is at most about several hundred meters, which is very small. [0003] In the microcellular system, base stations are frequently added or removed according to changes in regional communication needs. Due to such circumstances, base stations are often instal...
