For example, when a PHS communicator makes a call in transceiver mode to perform data communication with another PHS communicator, if the called PHS communicator is not at a field strength level that senses the call, the call is Fail. In this case, the PHS communication device normally performs a retry operation. However, in the called PHS communication device, if the electric field intensity level for detecting the call does not change, the call failure is repeated.

  For example, in Patent Document 1, when a PHS communication device transmits data in the transceiver mode, the relay PHS communication device relays data even if the transmission destination PHS communication device is outside the range of radio waves. A system is disclosed.

  Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, as a wireless communication device, a PHS communication device including a transceiver mode in which devices directly communicate with each other is used in addition to a public mode in which communication is performed via a base station.

  FIG. 1 is a functional block diagram of a PHS communication device (wireless communication device) 1 according to an embodiment of the present invention. As illustrated, the PHS communication device 1 according to the first embodiment includes a communication state monitoring unit 4, an electric field strength table 5, a state notification unit 6, a relay route information creation unit 7, and a PHS transceiver transmission / reception unit. 8.

  The communication state monitoring unit 4 receives from the PHS transceiver transmission / reception unit 8 the field strength of the call transmitted by the PHS communication device 1 other than its own device and the call number of the source PHS communication device 1 and stores them in the field strength table 5. To do.

  In addition, when the communication state monitoring unit 4 detects a call failure of a call in communication between PHS communication devices 1 other than its own device, a call destination indicated by a retry call by the PHS communication device 1 that failed to call will be described later. If the corresponding information (calling number) is registered with reference to the electric field strength table 5, the calling number of the PHS communication device 1 of the calling source and the calling destination is notified to the state notification unit 6.

  The electric field strength table 5 is a table in which the calling number and the electric field strength of the PHS communication device 1 acquired by the communication state monitoring unit 4 are stored. The electric field strength table 5 stores information for a plurality of vehicles, for example, as shown in FIG. The registration data in the electric field strength table 5 may be cleared every predetermined time, for example.

  The status notification unit 6 receives the relay route data received from the communication status monitoring unit 4 by adding the call number of the local station to the call number of the call source and the call destination PHS communication device 1 as the relay destination call number. The creation unit 7 is notified. An example of the relay route data is shown in FIG.

  The relay route information creating unit 7 adds the message type including the relay route data to the message data including the relay route data according to the message format predetermined between the PHS communication devices 1 (in this case, “route information identifier”). A relay route table to which data indicating) is added is generated. Then, the relay route information creation unit 7 passes the generated relay route table to the PHS transceiver transmission / reception unit 8. FIG. 4 illustrates a message format, FIG. 5 illustrates a message identifier table, and FIG. 6 illustrates a relay route table.

  When the transceiver call is received via the antenna, the PHS transceiver transmission / reception unit 8 measures the electric field strength of the received radio wave when the call is directed to a PHS communication device other than its own device, and the measured electric field strength is included in the transceiver call. The communication status monitoring unit 4 is notified together with the call number of the originating PHS communication device 1. When the received transceiver call is addressed to the own device, normal transceiver incoming processing is performed.

  When the PHS transceiver transmission / reception unit 8 receives the relay route table from the relay route information creation unit 7, the PHS transceiver transmission / reception unit 8 transmits the relay route table to the caller calling number set in the table.

  In addition, when the PHS transceiver transmission / reception unit 8 receives a message via an antenna, the PHS transceiver transmission / reception unit 8 refers to the type of message attached to the message. When the type of the referred message is “route information identifier”, the message data including the relay route table and the transmission data is used for relaying the message transmission source PHS communication device 1 to communicate with the other party that failed to receive the message first. The transmission relay data to which the message type (in this case, “relay identifier”) obtained from the message identifier table is added is generated. Then, the message is transmitted to the relay destination call number set in the relay route table of the message data. The transmission relay data is illustrated in FIG.

  Further, when the message type attached to the message received via the antenna is “relay identifier”, the PHS transceiver transmission / reception unit 8 refers to the relay route table in the received message data. If the call number of the local device is set as the relay destination call number in the referenced relay route table, the received data (transmission relay data) is addressed to the call destination call number set in the relay route table. Send. Further, in the referred relay route table, when the call number of the own device is set as the call destination call number, it is recognized as the transmission data addressed to the own device, and normal transceiver reception processing is performed.

  Next, processing in which the PHS communication device 1 according to the present embodiment transmits the relay route table will be described with reference to the flowchart of FIG.

  When the PHS transceiver transmission / reception unit 8 of the PHS communication device 1 receives a call addressed to the PHS communication device 1 other than its own device transmitted by the other PHS communication device 1 during the standby state (step S1: YES), The electric field strength and the caller's call number are acquired and notified to the communication state monitoring unit 4. The communication state monitoring unit 4 stores the electric field strength and the caller's calling number notified from the PHS transceiver transmission / reception unit 8 in the electric field strength table 5 (step S2). At this time, if the call number is already registered, the value of the electric field strength is updated with a new value.

  Further, the communication state monitoring unit 4 of the PHS communication device 1 determines whether or not the call has failed for this call (step S3). A method for determining whether or not the call has failed is arbitrary. For example, when the electric field strength and the caller's call number are acquired for the received call, information is stored in the electric field strength table 5 and the call is counted. Then, when a call whose count value reaches a predetermined value (for example, four times) is detected, it may be determined that the call has failed for the call. As a call counting method, for example, a call having the same caller call number and callee call number may be counted within a predetermined time from the initial count, and the count value may be cleared when the predetermined time elapses. .

  If it is determined in step S3 that the call has not failed (step S3: NO), the flow returns to step S1. If it is determined that the call has failed (step S3: YES), the communication state monitoring unit 4 searches whether the destination call number of the failed call is registered in the electric field strength table 5 (step S4). .

  As a result of searching the electric field strength table 5, when the call destination call number of the failed call is registered (step S4: YES), the communication state monitoring unit 4 sets the call source and call destination call numbers of the failed call. The status notification unit 6 is notified. The status notification unit 6 generates relay route data obtained by adding the call number of its own device as the relay destination call number to the notified call source and call destination call numbers, and passes the relay route data to the relay route information creation unit 7. The relay route information creation unit 7 generates a relay route table in which the message type is added to the message data including the notified relay route data (step S5).

  Then, the relay route information creation unit 7 transmits the generated relay route table to the caller calling number set in the relay route via the PHS transceiver transmission / reception unit 8 (step S6).

  In step S4, when the corresponding call number is not registered in the electric field strength table 5 (step S4: NO), the process is ended as it is.

  In this way, the PHS communication device 1 holds the electric field strength table 5 (see FIG. 2) based on the received radio wave. In addition, when communication failure between PHS communication devices 1 other than the device itself is detected by the PHS communication device 1, if the device itself can communicate with the call partner, the device relays data communication. The PHS communication device 1 that is the call source is notified that it can be performed.

  Next, the operation of the PHS communication device 1 according to the present embodiment will be described with reference to FIG. 9 as an example in which the PHS communication device 1C relays transmission data addressed to the PHS communication device 1B by the PHS communication device 1A. .

  First, the PHS communication device 1A transmits a call addressed to the PHS communication device 1B. If the PHS communication device 1B is in an area of an electric field strength level that can sense the call of the PHS communication device 1A, this call is successful, but here the PHS communication device 1B does not have the electric field strength that can sense the call of the PHS communication device 1A. Suppose that the call failed. In this case, the PHS communication device 1A performs a retry (recall) at a predetermined time interval (for example, every 5 seconds).

  On the other hand, the PHS communication device 1C, which is in the standby state and is in the area of the electric field strength level where the call of the PHS communication device 1A can be detected, indicates the call strength of the PHS communication device 1A and the call number that is the call source. The acquired information is stored in the electric field strength table 5 and calls are counted.

  When the PHS communication device 1C detects a call in which the count value of the call addressed to the PHS communication device 1B by the PHS communication device 1A reaches a predetermined value (for example, four times), the PHS communication device 1C determines that the call has failed.

  The PHS communication device 1 </ b> C searches the electric field strength table 5 for the call destination call number in the call that is determined to be a call failure. In this example, it is assumed that the calling number of the PHS communication device 1B is registered in the electric field strength table 5 of the PHS communication device 1C.

  When the PHS communication device 1C detects the call number of the PHS communication device 1B in the electric field strength table 5, the call number of the PHS communication device 1A that is the call source of the failed call and the call number of the PHS communication device 1B that is the call destination Then, relay route data is generated by adding the call number of the PHS communication device 1C as the relay destination call number. Then, according to a predetermined message format, a relay route table in which the message type (route information identifier) is added to the message data including the relay route data is generated, and the caller (PHS communication) set in the relay route data is generated. To the calling number of the machine 1A).

  The PHS communication device 1A receives a message (relay route table) from the PHS communication device 1C. The PHS communication device 1A recognizes that the message is information indicating a relay route because the type of message attached to the received message is a route information identifier. Then, the PHS communication device 1A relays the message transmission source PHS communication device 1C to communicate with the PHS communication device 1B, so that a message type (relay identifier) is added to the message data including the relay route table and the transmission data. The generated transmission relay data is generated and transmitted to the PHS communication device 1C.

  The PHS communication device 1C receives a message (transmission relay data) from the PHS communication device 1A. The PHS communication device 1C recognizes that the message includes data to be relayed because the type of the message attached to the received message is a relay identifier, and refers to the relay route table. In this example, since the call number of its own device (PHS communication device 1C) is set as the relay destination call number in the relay route table, the transmission relay data is called from the call destination of the relay route table (PHS communication device 1B). Send to the number.

  The PHS communication device 1B receives the message (transmission relay data) from the PHS communication device 1C. The PHS communication device 1B refers to the relay route table because the message type attached to the received message is the route information identifier. Then, since the call number of the own device is set as the call destination call number in the relay route table, it is recognized as transmission data addressed to the own device, and normal transceiver incoming processing is performed.

  As described above, according to the present embodiment, even when a certain PHS communication device 1 is in a position where the electric field strength capable of communicating with the other PHS communication device 1 cannot be obtained, The PHS communication device 1 of the source teaches the relay route of communication to the PHS communication device 1 of the transmission source, so that the PHS communication device 1 of the transmission source can perform data communication with the other party. In addition, when a call failure is detected without specifying a device that relays communication in advance, the PHS communication device 1 that can communicate with the call destination relays communication, so that it can flexibly cope with a changing communication environment. Communication can be reliably relayed.

(Other embodiments of the present invention)
Next, another embodiment of the present invention will be described. The PHS communication device 1 (wireless communication device) according to another embodiment of the present invention searches for another PHS communication device 1 that can relay communication when a call is unsuccessful. Hereinafter, other embodiments of the present invention will be described focusing on differences from the above-described embodiments of the present invention.

  When the communication state monitoring unit 4 recognizes the failure of the call originated by the own device, the communication state monitoring unit 4 acquires the call number of the other PHS communication device 1 registered in the electric field strength table 5 and together with the call destination call number of the failed call. The status notification unit 6 is notified.

  The status notification unit 6 adds the message type (from the relay route in this case) obtained from the message identifier table (see FIG. 5) to the message data including the destination call number of the failed call received from the communication status monitoring unit 4. The relay route confirmation data to which the data indicating the confirmation identifier ") is added is generated. And it transmits to the call number of the PHS communication apparatus 1 acquired from the electric field strength table 5 via the PHS transceiver transmission / reception unit 8. An example of the relay route confirmation data is shown in FIG.

  When the message type given to the message received via the antenna is “relay route confirmation identifier”, the PHS transceiver transmission / reception unit 8 notifies the communication state monitoring unit 4 of the call destination call number included in the message.

  The communication state monitoring unit 4 refers to the electric field strength table 5 for the call destination call number received from the PHS transceiver transmission / reception unit 8, and when the corresponding information is registered, the call source call number and the message Is notified to the status notification unit 6.

  The status notification unit 6 receives the relay route data, which is received from the communication status monitoring unit 4, by adding the call number of its own device as the relay destination call number to the call source call number and the call destination call number of the message. The information creation unit 7 is notified.

  For the message data including the relay route data received from the status notification unit 6, the relay route information creation unit 7 provides data indicating the message type (in this case, “route information identifier”) acquired from the message identifier table. Generate the assigned relay route table. And it transmits via the PHS transceiver transmission / reception part 8 to the calling number of the transmission origin set in the table.

  Next, the operation of the PHS communication device 1 according to the present embodiment will be described with reference to FIG. 11 as an example in which the PHS communication device 1C relays transmission data addressed to the PHS communication device 1B by the PHS communication device 1A. .

  First, the PHS communication device 1A transmits a call addressed to the PHS communication device 1B. Here, it is assumed that the PHS communication device 1B cannot sense the call and the call has failed. In this case, the PHS communication device 1A performs a retry (recall) at a predetermined interval (for example, every 5 seconds). When the number of retries reaches a predetermined value (for example, 3 times), the PHS communication device 1A recognizes that the call has failed.

  When the PHS communication device 1A recognizes that the call has failed, the PHS communication device 1 other than the failed call destination (for example, the PHS communication device 1C) among the PHS communication devices 1 registered in the electric field strength table 5 Get the call number of. Then, the PHS communication device 1A generates relay route confirmation data in which the message type “relay route confirmation identifier” is added to the message data including the call destination call number (call number of the PHS communication device 1B) of the failed call. , To the PHS communication device 1C.

  When the PHS communication device 1C receives a message with the message type “relay route confirmation identifier”, the PHS communication device 1C searches the electric field strength table 5 for the call destination call number indicated by the message. In this example, it is assumed that the calling number of the PHS communication device 1B is registered in the electric field strength table 5 of the PHS communication device 1C.

  When the PHS communication device 1C detects the call number of the PHS communication device 1B in the electric field strength table 5, the PHS communication device 1B calls the call number of the PHS communication device 1A that is the source of the message and the call number of the PHS communication device 1B that is the call destination. Relay route data is generated by adding the call number of its own device (PHS communication device 1C) as the relay destination call number. Then, a relay route table in which the message type (route information identifier) is added to the message data including the relay route data is generated and transmitted to the call number of the transmission source (PHS communication device 1A) set in the relay route data. To do.

  The PHS communication device 1A recognizes that the message is information indicating a relay route because the message type attached to the message received from the PHS communication device 1C is a route information identifier. Then, in order to communicate with the PHS communication device 1B by relaying the message transmission source PHS communication device 1C, the transmission relay data in which the message type (relay identifier) is added to the message data including the relay route table and the transmission data is generated. To the PHS communication device 1C.

  The PHS communication device 1C recognizes that the message includes data to be relayed because the message type attached to the message received from the PHS communication device 1A is a relay identifier, and refers to the relay route table. . In this example, since the call number of the own device (PHS communication device 1C) is set as the relay destination call number in the relay route table, the transmission relay data is addressed to the call destination call number of the relay route table (PHS communication device 1B). To).

  The PHS communication device 1B receives the message (transmission relay data) from the PHS communication device 1C. The PHS communication device 1B refers to the relay route table because the message type attached to the received message is the route information identifier. Then, since the call number of the own device is set as the call destination call number in the relay route table, it is recognized as transmission data addressed to the own device, and normal transceiver incoming processing is performed.

  As described above, according to another embodiment of the present invention, a PHS communication device 1 that has failed to call itself searches for a PHS communication device 1 that can relay communication with a communication partner and performs data communication with the partner. to enable.

  Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea.

  In the call failure determination, the number of retries is counted, and when the count value reaches a predetermined value, it may be determined that the call has failed, or when the number of calls is counted and the count value reaches a predetermined value It may be judged as a failure.

  Further, when the PHS communication device 1 detects a call failure of another PHS communication device 1 and the destination of the call is registered in the electric field strength table 5, a process for relaying communication (relay route table) However, the present invention is not limited to this. For example, when the corresponding call number is registered in the electric field strength table 5 and the registered electric field strength is a predetermined value or more, the communication is relayed. For this purpose, relay route table generation or the like may be performed.

  When a plurality of PHS communication devices 1 detect a call failure of one PHS communication device 1, each of the plurality of PHS communication devices 1 stores a relay route table in the PHS communication device 1 that has failed to make a call. Send. In this case, the PHS communication device 1 that failed to make a call may communicate based on the relay route table received first. Further, the PHS communication device 1 that has detected the call failure may add information on the electric field strength to the relay route table and transmit the information to the PHS communication device 1 that has failed to make the call. In this case, when the PHS communication device that failed to make a call receives the relay route table from the plurality of PHS communication devices 1, the PHS communication device compares the electric field strength values assigned to the plurality of received relay route tables, A relay route table having the highest strength may be selected, and communication may be performed based on the relay route table.

  When a failure in calling by any of the PHS communication devices 1 is detected, a relay route table is generated by searching for a PHS communication device 1 that can relay the communication, and the relay route table is stored in the PHS communication device 1 that has failed to call. You may use the management apparatus which has the function to notify.

  In this case, the management device monitors the communication between the PHS communication devices 1 and detects a failure of the call by any of the PHS communication devices 1, and can relay the communication with the call destination of the failed call. Search for. A method of searching for the PHS communication device 1 for relay is arbitrary. For example, confirmation information including a caller call number and a callee call number of a failed call is transmitted to each PHS communication device 1. Of the PHS communication devices 1 that have received the confirmation information, manage response information indicating that the PHS communication device 1 having the electric field strength capable of communicating with both PHS communication devices having the call number indicated by the confirmation information can relay communication with the call destination It may be sent to the device. Upon receiving the response information, the management device generates a relay route table with the transmission source as the relay device, and transmits the relay route table to the PHS communication device 1 that has failed to call. Also in this case, information on the electric field strength may be added to the response information. When the management device receives response information from a plurality of PHS communication devices 1, the source of the response information having the highest electric field strength may be determined as the relay device. The PHS communication device 1 that has received the relay route table from the management apparatus performs communication using the route indicated by the relay route table.

  A plurality of devices may be used for the PHS communication device that relays communication with the call destination. A method of searching for a plurality of PHS communication devices 1 for relay is arbitrary. For example, confirmation information including the call source call number of the failed call and confirmation information including the call destination call number of the failed call may be transmitted to each PHS communication device 1. Among the PHS communication devices 1 that have received the confirmation information, the PHS communication device 1 that has electric field strength that can communicate with the call number indicated by the received confirmation information communicates with the PHS communication device 1 with the call number of the call source and / or the call destination. Response information indicating that it can be transmitted to the management apparatus together with the call number of the own apparatus. Based on the received response information, the management device searches for a PHS communication device 1 that can communicate with both the call source and the call destination, and when there is a PHS communication device 1 that can communicate with both, relays the PHS communication device 1. If there is no PHS communication device 1 that can communicate with both parties, the PHS communication device 1 that can communicate with the call destination is searched for a device that can communicate with the PHS communication device 1 that can communicate with the call source. Specifically, a list of call numbers of the PHS communication device 1 that can communicate with the call source is transmitted to the PHS communication device 1 that can communicate with the call destination.

The PHS communication device 1 that has received the call number list determines whether it can communicate with any of the PHS communication devices 1 indicated in the list by referring to the electric field strength table, and can communicate with any of the PHS communication devices 1 in the list. Notifies the management device of the call number of the PHS communication device 1 capable of communication and the call number of the own device. Based on the received notification, the management device generates a relay route table corresponding to the relay route of “caller → PHS communication device that can communicate with the caller → PHS communication device that is the source of the notification → call destination”. Transmit to the original PHS communication device 1. The PHS communication device 1 that has received the relay route table from the management apparatus performs communication using the route indicated by the relay route table.
In addition, you may make it look for the apparatus which can communicate with the PHS communication apparatus 1 which can communicate with a call destination among the PHS communication apparatuses 1 which can communicate with the calling party.
