  FIG. 3 is an explanatory diagram showing an example of an arrangement state of a plurality of small base station apparatuses 30A to 30H. In the area 300A indicated by the one-dot chain line in the figure, the small base station device 30A to be managed focused in this example may wirelessly communicate with the user terminal device 10 or receive radio waves from nearby small base station devices. The wireless communication area that can be used is shown. The SC value described in each small base station apparatus in the figure is an identification value of a scrambling code uniquely assigned to each small base station apparatus. In addition, two-dot chain lines in the figure indicate management groups G-01 to G-04 that can be used for movement detection of the small base station device. Each management group is set so that, for each small base station device to be managed, at least one small base station device to be managed and at least one neighboring small base station device installed nearby. In FIG. 3, for example, the management group G-01 corresponding to the small base station device 30A is set so that the small base station device 30A and two small base station devices 30B and 30C in the vicinity thereof belong. Also, the management group G-02 corresponding to the small base station device 30B is set so that the small base station device 30B and two small base station devices 30A and 30D in the vicinity thereof belong.

  Tables 1 to 3 are examples of neighboring device lists created by the small base station devices 30A to 30C in FIG. 3 at a predetermined timing. The absolute value of RSCP (dBm) exemplified as the radio wave intensity in each table becomes smaller as the intensity of the received radio wave increases. For example, in the neighboring device list of the small base station device 30A shown in Table 1, the received radio wave from the small base station device 30B (SC = 502) is the strongest, and the received radio wave from the small base station device 30F (SC = 506). Is the weakest. The neighboring device lists in Tables 1 to 3 are transmitted from the small base station devices 30A to 30C to the base station management server 61, respectively.

  Tables 4 to 6 are examples of movement determination neighboring device lists received from the small base station devices 30A to 30C and stored in the base station management server 61, respectively. The neighboring device list for movement determination of the base station management server 61 is updated every time the neighboring device list is received from the small base station devices 30A to 30C. A column of “group affiliation identification information” is added to the movement determining neighbor device list stored in the base station management server 61. This “group affiliation identification information” is information for identifying whether each small base station device in the neighboring device list belongs to the management group corresponding to the neighboring device list. For example, the “group” of the small base station devices 30B and 30C (SC = 502, 503) belonging to the management group of the small base station device 30A in the movement determining neighboring device list of the small base station device 30A to be managed shown in Table 4 “1” is set in “affiliation identification information”, and “0” is set in “group affiliation identification information” of other small base station apparatuses 30D to 30F (SC = 504 to 506). Whether or not the small base station device 30A to be managed has been moved is determined based on whether the small base station device 30B or 30C belongs to the same management group G-01 in the movement determination neighboring device list of the small base station device 30A. This is determined by whether or not (SC = 502, 503) exists. For example, if the small base station devices 30B and 30C (SC = 502, 503) of the same management group exist in the movement determination neighboring device list of the small base station device 30A, the small base station device 30A moves. It is judged that it is not.

  FIG. 4 is an explanatory diagram showing an arrangement state of the small base station devices 30A to 30H when the small base station device 30A is moved from the state of FIG. Tables 7 to 9 are examples of neighboring device lists created by the small base station devices 30A to 30C after the small base station device 30A is moved. When the small base station device 30A is moved, the information of the small base station devices 30B (SC = 502) to 30F (SC = 506) arranged near the small base station device 30A before the movement is shown in Table 7. It disappears from the neighboring device list of the small base station device 30A shown. In the neighboring device list of the small base station device 30A after movement, records of other small base station devices (SC = 707, 708) arranged near the small base station device 30A appear. Further, the record of the small base station device 30A (SC = 501) disappears from the neighboring device list of the small base station devices 30B and 30C shown in Table 8 and Table 9. These neighboring device lists in Tables 7 to 9 are also transmitted from the small base station devices 30A to 30C to the base station management server 61, respectively.

  Tables 10 to 12 are examples of movement determination neighboring device lists received from the small base station devices 30A to 30C and stored in the base station management server 61 after the small base station device 30A moves. Whether or not the small base station device 30A to be managed has been moved is determined based on the small base station devices 30B and 30C (SC) belonging to the same management group G-01 in the movement determination neighboring device list of the small base station device 30A. = 502, 503). Here, the small base station devices 30B and 30C (SC = 502, 503) belonging to the same management group G-01 are not included in the movement determination neighboring device list shown in Table 10, so that the small size base station devices 30B and 30C (SC = 502, 503) belong to the same management group G-01. It is determined that the base station device 30A has moved.

  In order to more accurately determine the movement of the small base station device 30A, not only the movement determination neighboring device list corresponding to the small base station device 30A but also the same management group G-01 as the small base station device 30A is used. The determination may be made by further referring to the movement determination neighboring device list corresponding to the other small base station devices 30B, 30C to which the device belongs. Here, as shown in Table 11 and Table 12, when there is no record of the small base station device 30A in the movement determination neighboring device list of the small base station devices 30B and 30C, the small base station device It is determined that 30A has been moved. On the other hand, if there is a record of the small base station device 30A in each movement determination neighboring device list of the small base station devices 30B and 30C, it is determined that the small base station device 30A has not moved. In this case, it is considered that the records of the other small base station devices 30B and 30C belonging to the same management group G-01 have disappeared due to reasons other than the movement of the small base station device 30A. As a cause other than the movement of the small base station device 30A, for example, an obstacle such as a vehicle that blocks radio waves moves between the small base station device 30A and the other small base station devices 30B and 30C in the vicinity. It can be mentioned.

  FIG. 5 is a sequence diagram showing an example of communication when remote control is performed from the management system on the mobile communication network side so that the radio wave transmission / reception function of the small base station device 30A is stopped when the small base station device 30A moves. is there. The small base station device 30A to be managed executes the base station communication mode at a predetermined timing such as when the power is turned on, and performs wireless communication with a nearby small base station device (step 1). The small base station device 30A to be managed creates a neighboring device list for neighboring small base station devices that have been able to perform wireless communication, and transmits them to the base station management server 61 (step 2). Further, the neighboring small base station device creates a neighboring device list for the neighboring small base station devices that can perform wireless communication in the same manner as the small base station device 30A to be managed, and the base station management server 61 (Step 3). When receiving the neighboring device list from each small base station device, the base station management server 61 determines whether or not the small base station device 30A to be managed has been moved based on the received neighboring device list (step 4). ). When the base station management server 61 determines that the small base station device 30A to be managed has been moved, the base station management server 61 transmits the movement determination result to the communication network operation support system (OSS) 62 (step 5). When the communication network operation support system 62 receives the movement determination result indicating that the small base station device 30A has been moved, the communication network operation support system 62 issues a control command for stopping the radio wave transmission / reception function based on the movement determination result. It transmits to the apparatus 30A (step 6). The small base station device 30A controls to stop the radio wave transmission / reception function based on the control command received from the communication network operation support system 62 (step 7).

FIG. 6 is a flowchart illustrating an example of determination processing (processing corresponding to step 4 in FIG. 5) in which the base station management server 61 determines the movement of the small base station device 30A based on the neighboring device list. Upon receiving the neighboring device list from each small base station device, the base station management server 61 updates the movement determination neighboring device list corresponding to each small base station device based on the received neighboring device list (step 101). , 102). The base station management server 61 refers to the movement determination neighboring device list of the small base station apparatus 30A to be determined, and the neighbor belonging to the same management group G-01 as the small base station apparatus 30A is included in the movement determining neighboring device list It is determined whether or not the small base station devices 30B and 30C exist (step 103). When it is determined that there are no small base station devices 30B and 30C in the same management group (No in step 103), the base station management server 61 determines that the small base station devices 30B in the vicinity belonging to the same management group G-01. , 30C is read from a predetermined database in the server (step 104). The base station management server 61 determines whether or not the small base station device 30A to be determined exists in each of the movement determining neighboring device lists of the adjacent small base station devices 30B and 30C (step 105). If it is determined that the small base station device 30A to be determined does not exist (No in step 105), the base station management server 61 determines that the small base station device 30A to be determined has been moved, and displays the movement determination result. It transmits to the communication network operation support system (OSS) 62 (step 106).
On the other hand, if any of the neighboring small base station devices 30B and 30C exists in the movement judging neighboring device list of the small base station device 30A to be judged (Yes in Step 103), the neighboring small base station device 30B. , 30C, when the determination target small base station device 30A exists in each of the movement determination neighboring device lists (Yes in Step 105), the movement determination result is transmitted to the communication network operation support system (OSS) 62. Quit without doing.

As described above, according to the present embodiment, it is possible to easily determine whether or not the small base station device has been moved from the predetermined installation location based on the neighboring device list. In addition, when it is determined that the small base station apparatus has been moved, at least the radio wave transmission / reception function is controlled to ensure that the function restriction when the small base station apparatus is moved from a predetermined installation location is ensured. It can be carried out. In addition, since it is possible to determine whether or not the small base station device has been moved from a predetermined installation location based on the neighboring device list, it is not necessary to provide a GPS (Global Positioning System) function to the small base station device, Even when a small base station apparatus is installed in an environment where signals from GPS satellites cannot be received, it is possible to determine whether or not the small base station apparatus has been moved from a predetermined installation location.
Further, according to the present embodiment, the management group is set to include a predetermined number of neighboring small base station devices selected from the plurality of small base station devices included in the neighboring device list in descending order of received radio wave strength. doing. Then, since it is only necessary to determine whether or not the neighboring small base station devices belonging to the management group are included in the neighboring device list, the small base station device is not increased without increasing the processing load of the base station management server 61. It is possible to more reliably and easily determine whether or not has been moved.
In addition, according to the present embodiment, when it is determined that the small base station device has moved, the radio wave transmission / reception function from the small base station device is stopped. When a small base station apparatus is moved to an area where radio wave radiation from the station apparatus is restricted, radio wave radiation can be prevented from the small base station apparatus.

  In the above embodiment, the base station management server 61 on the network side determines whether or not the small base station device is moved, and the radio wave transmission / reception function is stopped when the small base station device is moved. Although remote control is performed from the network-side communication network operation support system (OSS) 62, the small base station device itself determines whether or not the small base station device has moved and controls the stop of the radio wave transmission / reception function. You may do it.

FIG. 7 is a flowchart illustrating an example of a processing procedure of the small base station apparatus that performs the stop control of the radio wave transmission / reception function by determining whether or not it has moved. The small base station device 30 executes the base station communication mode at a predetermined timing such as when the power is turned on, performs wireless communication with the nearby small base station device (step 201), A neighboring device list is created for the small base station device (step 202). The small base station device 30 determines whether or not there are neighboring small base station devices belonging to the same management group in the created neighboring device list (step 203). If it is determined that there are no small base station devices in the vicinity of the same management group (No in step 203), the small base station device 30 controls to stop the radio wave transmission / reception function (step 204).
As a femtocell, the small base station device 30 stops radio radiation when movement is detected. However, during the movement, the small base station device 30 periodically listens to radio waves from other small base station devices and transmits radio waves by itself. The mobile router mode may be configured to receive and function as a wireless LAN router device. Further, the small base station device 30 may resume the service by entering the femtocell base station mode when it matches the stored neighboring device list information of its home.

In the above embodiment, each small base station device 30 listens to radio waves from other small base station devices other than itself and creates a neighboring device list based on the strength of the radio waves. However, in addition to the neighboring device list for the small base station, it is possible to listen to the radio wave from the macro base station device and create the neighboring device list for the macro base station based on the strength of the radio wave. For example, when the above-described small base station device 30A is located in the area of two macro base station devices, each macro base station as shown in Table 13 in addition to the neighbor device list for the small base station in Table 1 above A macro base station neighboring device list including the strength of radio waves received from the device and identification information may be created. This macro base station neighbor device list may be stored in the small base station device 30A together with the small base station neighbor device list, or the base station management server 61 may update the movement determination neighbor device list. May be sent to. Further, the neighboring device list for the small base station and the neighboring device list for the macro base station may be combined and created as one neighboring device list.

  The macro base station neighboring device list created in addition can be used to increase the accuracy of the determination as to whether or not the small base station device 30 itself has been moved from a predetermined installation location. In particular, as a small-sized base station neighboring device list used for determining whether or not the small-sized base station device 30 itself has been moved from a predetermined installation location, the small-sized base station neighboring device created by the small-sized base station device 30 itself. This is effective when only lists can be used. In this case, by combining the small base station neighboring device list and the macro base station neighboring device list created by the small base station device 30 itself, the movement of the small base station device 30 can be accurately determined. . For example, when two macro base station devices (SC = 901, 902) disappear from the macro base station neighbor device list in Table 13 above, the small base station device 30 itself has surely moved from a predetermined installation location. Can be detected.

Moreover, although each said embodiment demonstrated the case where the communication relay apparatus which has the portability which can be moved and installed was a small base station apparatus which relays communication of a mobile communication terminal, this invention communicates with a user communication terminal. If the possible wireless communication area is relatively narrow and portable and can be moved and installed, in the case of a communication relay device other than the small base station device, for example, the communication relay device relays wireless LAN communication such as WiFi. The same applies to the case of a wireless LAN router device.
When the present invention is applied to a wireless LAN router, the wireless LAN router receives a radio wave from another nearby wireless LAN router installed near the wireless LAN router and creates a neighboring device list. Based on the list, it is possible to easily determine whether or not the wireless LAN router device has been moved from a predetermined installation location. In addition, when it is determined that the wireless LAN router device has been moved, at least the radio wave transmission / reception function is controlled to ensure that the function restriction when the wireless LAN router device is moved from a predetermined installation location is ensured. It can be carried out. Furthermore, the wireless LAN router device can reduce the mutual interference between the wireless LAN router devices provided by the same operator by grasping the position of other nearby wireless LAN router devices installed in the vicinity thereof. can do. The information regarding the provider providing the wireless LAN router device may be determined based on information included in the radio wave transmitted from the wireless LAN router device.
Further, in each of the above embodiments, in order to detect movement of the small base station device, another communication relay device with a different operator as the operating entity may be included in the neighboring device list. For example, a publicly available large base station apparatus that can read the center frequency that is not owned by the communication carrier that installs and operates the small base station apparatus may be included. More specifically, the center frequency setting of the target reception frequency, which is one of the listening settings for the surrounding environment in order for the small base station device to create the neighboring device list at a predetermined timing, is set to the baseband of the small base station device. By periodically changing the unit, it is possible to include other communication relay devices that are not owned by the communication carrier that installs and operates the small base station device in the neighboring device list.
In each of the above embodiments, when the small base station apparatus is moved, the radio wave transmission / reception function is controlled to stop. However, by stopping the other functions of the small base station apparatus, the small base station apparatus You may make it regulate the communication relay function by an apparatus. Further, in each of the above embodiments, it may be controlled to stop at least the radio wave transmission function among the functions of the small base station apparatus. For example, the small base station apparatus capable of independently controlling the radio wave transmission function and the radio wave reception function. When the is moved, it may be controlled to stop only the radio wave transmission function.
Further, the user terminal device 10 is not limited to a mobile communication terminal such as a mobile phone, but may be a PDA (Personal Digital Assistants) or a small device as long as it can communicate with an external communication network via a mobile relay communication device. It may be a notebook personal computer or other communication terminal device.

  Further, in each of the above embodiments, the case where the scrambling code (SC) is used as the identification information of the small base station device 30 that is a communication relay device or the macro base station device has been described, but this scrambling code (SC) Instead of the cell ID, a cell ID (Cell ID) that is a base station identification number broadcast by the base station apparatus may be used.
