  Hereinafter, specific embodiments of a location registration system for a radio base station according to the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
First, an overall configuration of a system including a radio base station location registration system according to Embodiment 1 of the present invention will be described. FIG. 1 is an overall configuration diagram of a system including a radio base station location registration system according to Embodiment 1 of the present invention. The radio base station location registration system according to the first embodiment includes at least a radio base station 1 and a GPS-equipped cellular terminal 2.

  The radio base station 1 uses an IP network as a communication infrastructure. The IP network includes an external IP network 3 and a local IP network 8. The external IP network 3 is further connected to a cellular network 4.

  The cellular network 4 is the same as a communication infrastructure in a conventional mobile phone. In the cellular network 4, devices such as a positioning server 6, a base station information management server 7, and a conventional wireless base station 13 are arranged. A gateway device 5 is disposed between the external IP network 3 and the cellular network 4.

  A router 9 is arranged between the radio base station 1 and the external IP network 3. The router 9 is a device that transfers a packet through the network layer. Specifically, the packet data from the radio base station 1 is delivered to the devices in the cellular network 4 via the gateway device 5 using the network layer. Further, the router 9 receives packet data delivered from a device in the cellular network 4 via the gateway device 5 using the network layer and delivers it to the radio base station 1.

  A bridge 11 (bridge 11a, bridge 11b, etc.) may be arranged between the radio base station 1 and the router 9. The bridge 11 is a device that extends the network at the data link layer. Further, the DHCP server 10 may be arranged in the local IP network 8 to which the radio base station 1 is connected. The DHCP server 10 is a server that performs a DHCP (Dynamic Host Configuration Protocol) service. If the DHCP server 10 is installed, TCP / IP communication can be performed only by connecting the wireless base station 1 having the external IP network 3 as a communication infrastructure to the local IP network 8. That is, the wireless base station 1 can be used without any special setting by physically connecting the wireless base station 1 to the local IP network 8 by DHCP (plug and play is realized). . Here, since the mechanism of DHCP is the same as that of conventional DHCP, details are omitted. For example, when an individual uses the wireless base station 1 at home, the wireless base station 1 can be directly connected to the router 9 without installing the DHCP server 10 or the bridge 11.

  The radio base station 1 acquires position information from the GPS-equipped cellular terminal 2 based on the connection state of the IP network, and sets it as a registered position of the radio base station 1. The GPS-equipped cellular terminal 2 receives GPS signals from the GPS satellites 12 (GPS satellites 12a, GPS satellites 12b, GPS satellites 12c, etc.), and acquires position information of the GPS-equipped cellular terminals 2 based on the GPS signals. Then, the GPS-equipped cellular terminal 2 transmits the position information of the GPS-equipped cellular terminal 2 to the radio base station 1 using a cellular radio signal.

  For example, when the wireless base station 1 physically connects the wireless base station 1 to the local IP network 8, the wireless base station 1 receives a packet such as a DHCP provision packet or a DHCP acknowledgment packet from the DHCP server 10. The network setting by is completed, and communication by TCP / IP becomes possible. Packets such as a DHCP provision packet and a DHCP confirmation response packet at this time include information on the MAC (Media Access Control) address of a device (device) connected to the wireless base station 1 in the header. Specifically, when the wireless base station 1 is connected to the DHCP server 10 via the bridge 11, the MAC address information of the bridge 11 is included in the header. When the wireless base station 1 is directly connected to the DHCP server 10 without going through the bridge 11, the MAC address information of the DHCP server 10 is included in the header. When the wireless base station 1 is directly connected to the router 9 without installing the DHCP server 10 or the bridge 11, the header of the packet received by the wireless base station 1 includes the MAC address information of the router 9. It is. In any case, the radio base station 1 receives the MAC address of the device (device) connected to the radio base station 1. The radio base station 1 can detect the connection state of the IP network based on the MAC address included in the header of the received packet.

  Then, the wireless base station 1 acquires position information from the GPS-equipped cellular terminal 2 based on the detected connection state of the IP network and sets it as a registered position of the wireless base station 1. For example, when the wireless base station 1 is changed from the state connected to the bridge A11a to the state connected to the bridge B11b, the MAC address included in the header of the packet received by the wireless base station 1 changes. By detecting the change, it is possible to detect a change in the connection state of the IP network. When the wireless base station 1 detects a change in the connection state of the IP network, the position information can be acquired from the GPS-equipped cellular terminal 2 and set as the registered position of the wireless base station 1. According to such a radio base station location registration system, the location registration of the radio base station 1 can be simplified.

  The radio base station 1 detects the connection state of the IP network based on the MAC address included in the header of the received packet, instead of detecting the connection state of the IP network based on the IP address included in the header of the received packet. It is also possible to detect the state. For example, when the connection destination of the wireless base station 1 is changed from one local IP network 8a to another local IP network 8b, the IP address included in the header of the received packet changes. Therefore, the radio base station 1 can detect the change in the connection state of the IP network by detecting the change in the IP address. The radio base station 1 can also detect the connection state of the IP network based on the MAC address and the IP address (for example, changes thereof) included in the header of the received packet.

  Here, since a device such as the bridge 11 has a MAC address but is not assigned an IP address, the MAC address is compared with the method of detecting the connection state of the IP network based on the IP address. It is considered that the method of detecting the connection state of the IP network based on the above can detect a finer change. In addition, the MAC address is unique to the device (device) and basically does not change, while considering that the IP address can change periodically, for example, the connection of the IP network based on the IP address Compared to the method of detecting the state, the method of detecting the connection state of the IP network based on the MAC address is considered to be able to detect the connection state (change or the like) of the IP network more accurately.

  Further, the radio base station 1 can detect the connection state of the IP network based on ON / OFF of the power supply of the radio base station 1. In this way, the connection state can be easily detected. In addition, when changing the physical position of the radio base station 1, it is considered that there are many cases where the power of the radio base station 1 is once turned off and then turned on after changing the connection destination. Network connection state detection operation can be reduced.

  When a cellular terminal (not shown) makes an emergency call such as No. 110 or No. 119 through the radio base station 1 in which location registration is performed in this way, GPS is installed in the cellular terminal when transmitting location information. Even when it is not, the registered position of the registered radio base station 1 can be transmitted as the approximate position of the cellular terminal.

  As a specific location registration method, the base station information management server 7 can store the registration position of the radio base station 1, or the radio base station 1 can store the registration position of the radio base station 1. You can also let them.

  Further, when acquiring the position information of the GPS-equipped cellular terminal 2, the positioning calculation can be performed by the positioning server 6, or can be performed by the GPS-equipped cellular terminal 2. The GPS-equipped cellular terminal 2 can also obtain assist data from the positioning server 6 when the GPS-equipped cellular terminal 2 performs a positioning calculation. Then, the GPS-equipped cellular terminal 2 can obtain position information of the GPS-equipped cellular terminal 2 by performing a positioning calculation based on the assist data obtained from the positioning server 6 and the signal from the GPS satellite 12. Here, the assist data is data including information (assist information) such as orbit information of GPS satellites.

  Next, the configuration of radio base station 1 and GPS-equipped cellular terminal 2 in the radio base station location registration system according to Embodiment 1 of the present invention will be described. FIG. 2 is a block diagram illustrating configurations of radio base station 1 and GPS-equipped cellular terminal 2 in the radio base station location registration system according to the first embodiment of the present invention.

  The wireless base station 1 includes a cellular transceiver unit 101 that transmits and receives cellular radio signals to and from the GPS-equipped cellular terminal 2, an IP network connection state detection unit 102 that detects a connection state of the IP network, and a connection state of the IP network. And a location registration unit 103 that obtains the location information from the GPS-equipped cellular terminal and sets it as the registered location of the radio base station 1. The wireless base station 1 also transmits cellular packets to other devices (devices) in the IP network and receives packets from other devices (devices) in the IP network, and cellular wireless communication. And a protocol conversion unit 105 that performs communication protocol conversion for performing communication across the two, corresponding to the difference in the communication method of TCP / IP communication in the IP network. For this reason, the protocol converter 105 is arranged between the cellular transceiver 101 and the IP network interface 104. Furthermore, it holds terminal authentication information for acquiring location information after performing authentication between the cell ID information holding unit 106 that holds the cell ID information of the radio base station 1 and the specific GPS-equipped cellular terminal 2. A terminal authentication information holding unit 107 is included. Further, the radio base station 1 may include a position information holding unit 108 that stores a registered position of the radio base station 1.

  As described above, the cellular transceiver 101 transmits and receives cellular radio signals to and from the GPS-equipped cellular terminal 2. For example, the cellular transceiver unit 101 receives position information of the GPS-equipped cellular terminal 2 acquired by the GPS-equipped cellular terminal 2. At this time, the cellular transmission / reception unit 101 can receive “the time when the GPS-equipped cellular terminal 2 receives the GPS signal” associated with the position information of the GPS-equipped cellular terminal 2.

  The IP network connection state detection unit 102 detects the connection state of the IP network as described above. At this time, the IP network connection state detection unit 102 can also detect the connection state of the IP network based on the MAC address of the device connected to the wireless base station 1. Further, the IP network connection state detection unit 102 determines the connection state of the IP network based on the IP address of the device connected to the wireless base station 1 instead of the MAC address of the device connected to the wireless base station 1. It can also be detected. The IP network connection state detection unit 102 can also detect the connection state of the IP network based on the MAC address and IP address of the device connected to the wireless base station 1. Further, the IP network connection state detection unit 102 can detect the connection state of the IP network based on ON / OFF of the power supply of the wireless base station 1. By detecting the connection state of the IP network based on the MAC address or the IP address, the connection state (change or the like) can be easily detected. Further, by detecting based on the MAC address, it is possible to detect a finer change as compared with the case of detecting based on the IP address, and it is possible to detect the connection state (change and the like) of the IP network more accurately.

  As described above, the position registration unit 103 acquires position information from the GPS-equipped cellular terminal 2 based on the connection state of the IP network, and sets it as the registered position of the radio base station 1. At this time, if the GPS-equipped cellular terminal 2 cannot acquire its own location information based on the signal from the GPS satellite, the location registration unit 103 acquires the past location information of the GPS-equipped cellular terminal 2 to obtain the wireless base station. The registered position of the station 1 can also be used. By doing in this way, location registration can be easily performed even in places where GPS signals cannot be received, such as indoors and underground shopping streets. At this time, if the time at which the wireless link with the GPS-equipped cellular terminal 2 is established is within a predetermined time from the time when the GPS-equipped cellular terminal 2 receives the GPS signal, the location registration unit 103 It is also possible to obtain the location information of the wireless base station 1 as a registered location. In this way, the registration position error can be suppressed within a reasonable range. As a method for the location registration unit 103 to register the location of the radio base station 1, the location information holding unit 108 can store the registered location of the radio base station 1, or the base station information management server 7 It is also possible to store the registered position of the radio base station 1.

For example, when the wireless base station 1 detects that the connection state of the IP network has changed, it starts location registration (step S500). Thereafter, the radio base station 1 does not transmit a position information acquisition request to the GPS-equipped cellular terminal 2 until a radio link with the predetermined GPS-equipped cellular terminal 2 is established (see steps S507 and S508).

  On the other hand, when a radio link with the conventional radio base station 13 is established (step S501), the GPS-equipped cellular terminal 2 transmits a signal requesting assist data to the positioning server 6. Then, the positioning server 6 receives a signal requesting assist data from the GPS-equipped cellular terminal 2 (step S502).

  Next, the positioning server 6 transmits assist data to the GPS-equipped cellular terminal 2 based on a signal requesting assist data. Then, the GPS-equipped cellular terminal 2 receives assist data from the positioning server 6 (step S503). Here, the assist data is data including information (assist information) such as orbit information of GPS satellites.

  Next, the GPS-equipped cellular terminal 2 receives the GPS signal from the GPS satellite 12 using the assist data (step S504). At this time, the GPS-equipped cellular terminal 2 stores the time when the GPS signal is received.

  Next, the GPS-equipped cellular terminal 2 performs a positioning calculation based on the received GPS signal and assist data, and acquires position information of the GPS-equipped cellular terminal 2 (step S505). Then, the positional information and the time when the GPS signal is received are stored in association with each other (step S506).

  Thereafter, when a radio link between the predetermined GPS-equipped cellular terminal 2 and the radio base station 1 is established (step S507), the GPS-equipped cellular terminal 2 establishes a radio link between the GPS-equipped cellular terminal 2 and the radio base station 1. Memorize the time.

  In addition, when a wireless link between a predetermined GPS-equipped cellular terminal 2 and the radio base station 1 is established (step S507), the GPS-equipped cellular terminal 2 transmits a position information acquisition request. Then, the radio base station 1 receives the position information acquisition request. (Step S508).

  Next, the GPS-equipped cellular terminal 2 transmits the position information of the GPS-equipped cellular terminal 2 and the time when the GPS signal is received to the radio base station 1 based on the received position information acquisition request. Then, the radio base station 1 receives the position information of the GPS-equipped cellular terminal 2 and the time when the GPS signal is received (step S509).

  Next, the radio base station 1 compares the time when the GPS signal is received with the time when the radio link between the GPS-equipped cellular terminal 2 and the radio base station 1 is established, and within a predetermined time from the time when the GPS signal is received Then, it is determined whether or not a radio link between the GPS-equipped cellular terminal 2 and the radio base station 1 has been established (step S510). If it is not within the predetermined time (step S510, NO), the position information acquisition request is not transmitted to the GPS-equipped cellular terminal 2 until the wireless link with the predetermined GPS-equipped cellular terminal 2 is established again (step S510). (See S507 and S508). On the other hand, if it is within the predetermined time (step S510, YES), the radio base station 1 registers the received location information of the GPS-equipped cellular terminal 2 as the registration location of the radio base station 1. Specifically, the radio base station 1 stores the registered position of the radio base station 1 in the position information holding unit 108 of the radio base station 1 (step S511). Then, the location registration is completed (step S512).

  As a location registration method, the radio base station 1 transmits the registration location and cell ID information of the radio base station 1 to the base station information management server 7, and the base station information management server 7 receives this ( Next, a method is conceivable in which the base station information management server 7 stores the registered location and cell ID information of the wireless base station 1 (step S514) and completes the location registration (step S515).

  As a modification of the operation described with reference to FIG. 5, a method in which the positioning calculation is performed by the positioning server 6 without performing the positioning calculation in the GPS-equipped cellular terminal 2 is also conceivable. Specifically, as shown in FIG. 6, the GPS-equipped cellular terminal 2 transmits satellite supplementary information (such as a GPS signal) to the positioning server 6, which is received by the positioning server 6 (step S601), The server 6 performs positioning calculation to acquire position information (step S602), and the positioning server 6 transmits the acquired position information to the GPS-equipped cellular terminal 2, which is received by the GPS-equipped cellular terminal 2 ( Step S603) Operation is also conceivable.
