Description

Wireless terminal device, communication system, and communication method

The present invention relates to communication technology, and more particularly, to a wireless terminal device, a communication system, and a communication method that execute communication using an identifier.

１A single mobile phone may be configured to be separable like a parent device and a child device. Each of the parent device and the child device is provided with an external communication function, but in order to operate with one telephone number, a state where both external communication functions are enabled at the same time should be avoided. Therefore, when the parent device and the child device are combined, only the external communication function of the parent device is effective. On the other hand, when the parent device and the child device are separated, the external communication function of the parent device and the external communication function of the child device are alternately enabled at regular time intervals (see, for example, Patent Document 1).

(Example 1)
Before describing the present invention specifically, an outline will be given first. Example 1 relates to a communication system including a plurality of wireless terminal devices and a base station device, and in which communication is performed via the base station device. An example of a communication system is a commercial wireless system. In the commercial wireless system, different identifiers (hereinafter referred to as “first identifiers”) are assigned to identify each of the plurality of wireless terminal devices. The base station device uses the first identifier to execute a call to the wireless terminal device or to transmit a signal to the wireless terminal device. Therefore, even when one user communicates using two wireless terminal devices according to the situation, a different first identifier is assigned to each wireless terminal device. This is because inconsistency occurs in the communication system when there are a plurality of wireless terminal devices to which the same first identifier is assigned in the communication system.

On the other hand, there are situations where it is desirable to use a common first identifier for two wireless terminal devices used by one user. For example, a police officer, a rescue team (hereinafter referred to as “user”) or the like, a wireless terminal device (hereinafter referred to as “mobile wireless terminal device”) mounted on a vehicle, and a wireless terminal device (such as a “mobile wireless terminal device”) This is a case where “portable wireless terminal device”) is used properly according to the situation. Generally, a user uses a portable wireless terminal device when away from the vehicle. On the other hand, when the user is in the vehicle or on the vehicle side, the user uses the mobile wireless terminal device in order to suppress the power consumption of the battery-driven portable wireless terminal device. Under such circumstances, if a different first identifier is assigned to the portable wireless terminal device and the mobile wireless terminal device, the first identifier of the mobile wireless terminal device is set when the user is away from the vehicle. The user cannot answer the specified call.

In order to share one first identifier between two wireless terminal devices, the mobile wireless terminal device and portable wireless terminal device (hereinafter collectively referred to as “wireless terminal device”) according to the present embodiment execute the following processing: . When the mobile wireless terminal device and the portable wireless terminal device are not close to each other, the first identifier becomes valid in the portable wireless terminal device, and the first identifier becomes invalid in the mobile wireless terminal device. On the other hand, when the mobile wireless terminal device and the portable wireless terminal device are close to each other, the first identifier is valid in the mobile wireless terminal device, and the first identifier is invalid in the portable wireless terminal device.

FIGS. 1A to 1B show the configuration of the communication system 100 according to the first embodiment. The communication system 100 includes a mobile wireless terminal device 10, a portable wireless terminal device 12, and a base station device 14. Here, for the sake of clarity, only the mobile wireless terminal device 10 and the portable wireless terminal device 12 used by one user are shown, but the mobile wireless terminal device 10 and the portable wireless terminal device 12 are shown. The number of each is not limited to “1”.

First, a configuration common to FIGS. 1A to 1B will be described. The mobile wireless terminal device 10 is a wireless terminal device mounted on a vehicle (not shown), and operates with a power supply supplied from a battery mounted on the vehicle. In addition, the mobile wireless terminal device 10 can execute communication by commercial wireless. Since publicly known technology may be used for commercial radio, description thereof is omitted here. The mobile wireless terminal device 10 performs voice communication using PTT (Push to Talk). In PTT, transmission is started when a button provided on the mobile radio terminal apparatus 10 is depressed by the user, and transmission is terminated when the button is released. On the other hand, if the button is not pressed, the user only listens to the message. In order to execute such business wireless communication, the mobile wireless terminal device 10 is given a first identifier. Furthermore, the mobile wireless terminal device 10 also executes wireless communication using a wireless communication method different from that for business use. An example of such wireless communication is short-range wireless communication or radio wave beacon. In the following, it is assumed that short-range wireless communication is used for the sake of clarity.

The portable wireless terminal device 12 is a portable wireless terminal device that can be carried by the user, and operates with a power source supplied from a built-in battery. Generally, the capacity of the battery built in the portable wireless terminal device 12 is smaller than the capacity of the battery mounted on the vehicle. Similar to the mobile wireless terminal device 10, the portable wireless terminal device 12 can perform communication by commercial wireless and performs voice communication by PTT. In order to execute such business wireless communication, the portable wireless terminal device 12 is also given a first identifier. Further, the first identifier assigned to the portable wireless terminal device 12 is the same as the first identifier assigned to the mobile wireless terminal device 10. Further, like the mobile radio terminal device 10, the portable radio terminal device 12 also executes radio communication by short-range radio communication, which is a radio communication method different from commercial radio.

The base station apparatus 14 corresponds to business radio. In addition, the base station device 14 connects the mobile wireless terminal device 10 and the portable wireless terminal device 12 by commercial radio at one end side. Therefore, when wireless terminal devices including the mobile wireless terminal device 10 and the portable wireless terminal device 12 are connected to the base station device 14, communication between the wireless terminal devices is performed via the base station device 14. The base station device 14 assigns a downlink channel and an uplink channel to each wireless terminal device. The above-described first identifier is used when performing such channel allocation and calling of the wireless terminal device that is the preceding stage. Furthermore, the base station apparatus 14 is connected to a network (not shown) on the other end side. A server and a communication device may be connected to this network.

FIG. 1A shows a case where the mobile wireless terminal device 10 and the portable wireless terminal device 12 are not in proximity. An area 16 is formed around the mobile wireless terminal device 10, and the area 16 indicates an area in which the mobile wireless terminal device 10 can communicate by short-range wireless communication. Therefore, the above-mentioned non-proximity corresponds to a state in which the portable wireless terminal device 12 exists outside the area 16 and the mobile wireless terminal device 10 and the portable wireless terminal device 12 cannot communicate by short-range wireless communication. In this case, the portable wireless terminal device 12 communicates with the base station device 14 by commercial radio, and the mobile wireless terminal device 10 does not perform communication with the base station device 14. For this reason, the first identifier is validated in the portable radio terminal apparatus 12 and the first identifier is invalidated in the mobile radio terminal apparatus 10.

FIG. 1B shows a case where the mobile wireless terminal device 10 and the portable wireless terminal device 12 are close to each other. As illustrated, the proximity corresponds to a state in which the portable wireless terminal device 12 exists in the area 16 and the mobile wireless terminal device 10 and the portable wireless terminal device 12 can communicate with each other by short-range wireless communication. In this case, the mobile radio terminal apparatus 10 communicates with the base station apparatus 14 by business radio, and the portable radio terminal apparatus 12 does not execute communication with the base station apparatus 14. For this reason, the first identifier is validated in the mobile radio terminal apparatus 10 and the first identifier is invalidated in the portable radio terminal apparatus 12. That is, based on the distance between the mobile wireless terminal device 10 and the portable wireless terminal device 12, control is performed so that only one of the wireless communication functions is effective. When the same first identifier assigned to the mobile wireless terminal device 10 and the portable wireless terminal device 12 is designated and a communication device (not shown) transmits a signal, as shown in FIGS. Either one receives the signal.

FIG. 2 shows a configuration of the wireless terminal device 20 according to the first embodiment. The wireless terminal device 20 has a configuration common to the mobile wireless terminal device 10 and the portable wireless terminal device 12 in FIGS. Note that different configurations of the mobile wireless terminal device 10 and the portable wireless terminal device 12 are omitted from the wireless terminal device 20. The wireless terminal device 20 includes a first communication unit 30, a second communication unit 32, a control unit 34, an operation unit 36, a call unit 38, an acquisition unit 40, and a storage unit 42. The first communication unit 30 includes a receiving unit 44.

1st communication part 30 performs communication by business radio. Therefore, the wireless terminal device 20 in FIG. 1 can communicate with a wireless terminal device 20 and a communication device (not shown) via the base station device 14. As described above, in business radio, the first identifier is used to identify each radio terminal device 20. In particular, the receiving unit 44 of the first communication unit 30 uses the first identifier assigned in common between the plurality of wireless terminal devices 20, that is, the mobile wireless terminal device 10 and the portable wireless terminal device 12 of FIG. By doing so, a signal for commercial wireless is received. The receiving unit 44 outputs the received signal to the control unit 34. The first communication unit 30 inputs a signal to be transmitted from the control unit 34.

The second communication unit 32 performs short-distance wireless communication different from business wireless communication, for example, communication using Bluetooth (registered trademark). Therefore, the second communication unit 32 communicates directly with another wireless terminal device 20 without passing through the base station device 14. Here, when the commercial radio is compatible with the long-range wireless communication, the short-range wireless communication is the short-range wireless communication. When the commercial wireless is compatible with the first wireless communication method, the short-range wireless communication is the first. 2 wireless communication systems. Since publicly known technology may be used for commercial wireless and short-range wireless communication, description thereof is omitted here. Note that the second communication unit 32 may use a radio beacon instead of the short-range wireless communication. At this time, the transmission distance of the radio beacon is shorter than the transmission distance of the commercial radio and is close to the transmission distance of the short-range wireless communication. As described above, in the following, short-range wireless communication will be described, and radio wave beacons will be described as necessary.

In short-range wireless communication, different identifiers (hereinafter referred to as “second identifiers”) are assigned to identify each of the plurality of wireless terminal devices 20. It can be said that this second identifier is given independently among the plurality of wireless terminal devices 20. When the second communication unit 32 transmits the signal, the second communication unit 32 includes the second identifier assigned to the wireless terminal device 20 in the signal. In addition, the second communication unit 32 receives a signal including the second identifier assigned to another wireless terminal device 20 that is a signal transmission source. The second communication unit 32 outputs the received signal to the control unit 34 and inputs a signal to be transmitted from the control unit 34.

The storage unit 42 stores the first identifier and the second identifier assigned to the wireless terminal device 20. Furthermore, the storage unit 42 also stores a second identifier assigned to another wireless terminal device 20 having a first identifier having the same value as the first identifier used in the receiving unit 44. This will be described with reference to FIG. 1. When the wireless terminal device 20 is the mobile wireless terminal device 10, this corresponds to storing the second identifier of the portable wireless terminal device 12. In the case of the portable wireless terminal device 12, this corresponds to storing the second identifier of the mobile wireless terminal device 10.

3 (a)-(b) show the data structure of the database stored in the storage unit 42. FIG. FIG. 3A shows a data structure of a database stored in the storage unit 42 of the mobile radio terminal apparatus 10 of FIG. The first identifier “500” and the second identifier “10” assigned to the mobile wireless terminal device 10 are stored, and the second identifier “20” assigned to the portable wireless terminal device 12 is also “registered second identifier”. Is stored. On the other hand, FIG. 3B shows a data structure of a database stored in the storage unit 42 of the portable wireless terminal device 12 of FIG. The first identifier “500” and the second identifier “20” given to the portable radio terminal device 12 are stored, and the second identifier “10” given to the mobile radio terminal device 10 is also “registered second identifier”. Is stored. Thus, in the mobile radio terminal apparatus 10 and the portable radio terminal apparatus 12, the first identifier is common, but the second identifier is different from each other. Returning to FIG.

The control unit 34 controls the first communication unit 30 so that one of the operation state in which the business wireless function is valid and the sleep state in which the business wireless function is invalid are set. In the operating state, the control unit 34 causes the first communication unit 30 to execute communication using the first identifier stored in the storage unit 42. Therefore, the control unit 34 causes the reception unit 44 to receive a signal including the first identifier stored in the storage unit 42. On the other hand, in the dormant state, the control unit 34 does not cause the first communication unit 30 to perform communication. Furthermore, the control part 34 makes the 1st communication part 30 perform position registration to the base station apparatus 14, when switching the 1st communication part 30 from a dormant state to an operation state. Since a well-known technique should just be used for position registration, description is abbreviate | omitted here.

Here, the control unit 34 is in an operating state depending on whether or not the other wireless terminal device 20 to which the second identifier stored in the storage unit 42 is assigned is close to the wireless terminal device 20, Control whether to go to sleep. Specifically, the second communication unit 32 searches for another wireless terminal device 20 having the “registered second identifier” stored in the storage unit 42 by short-range wireless communication. The control unit 34 checks whether or not the second identifier included in the signal received by the second communication unit 32 matches the “registered second identifier” stored in the storage unit 42. The control unit 34 determines that the other wireless terminal devices 20 are close if they match, and determines that the other wireless terminal devices 20 are not close if they do not match. Thus, the control unit 34 receives the second identifier included in the signal received by the second communication unit 32 according to whether or not the second identifier included in the storage unit 42 matches the “registered second identifier”. It is controlled whether or not the unit 44 performs reception.

Hereinafter, the processing by the control unit 34 will be described separately for the case where the wireless terminal device 20 is the mobile wireless terminal device 10 and the case where it is the portable wireless terminal device 12. First, processing when the wireless terminal device 20 is the mobile wireless terminal device 10 will be described. When the power of the mobile radio terminal apparatus 10 is turned on from off, the control unit 34 of the mobile radio terminal apparatus 10 puts the first communication unit 30 into a dormant state. In addition, when the control unit 34 determines that another wireless terminal device 20, that is, the portable wireless terminal device 12 is in proximity by the above-described processing, the control unit 34 puts the first communication unit 30 into an operating state. That is, the control unit 34 validates the first identifier. On the other hand, when the control unit 34 determines that the portable wireless terminal device 12 is not in proximity in a state where the first communication unit 30 is in an operating state, the control unit 34 puts the first communication unit 30 into a dormant state. That is, the control unit 34 invalidates the first identifier.

Next, processing when the wireless terminal device 20 is the portable wireless terminal device 12 will be described. When the power of the portable wireless terminal device 12 is turned on from off, the control unit 34 of the portable wireless terminal device 12 puts the first communication unit 30 into a dormant state. Moreover, the control part 34 makes the 1st communication part 30 an operation state, when it determines with other wireless terminal devices 20, ie, the mobile wireless terminal device 10, not approaching by the above-mentioned process. That is, the control unit 34 validates the first identifier. On the other hand, when the control unit 34 determines that the portable wireless terminal device 12 is approaching in a state where the first communication unit 30 is in the operating state, the control unit 34 puts the first communication unit 30 into the dormant state. That is, the control unit 34 invalidates the first identifier.

The operation unit 36 includes a button for PTT. When the first communication unit 30 is in an operating state, the operation unit 36 outputs a transmission instruction to the control unit 34 while the button is pressed. When receiving a transmission instruction from the operation unit 36, the control unit 34 causes the first communication unit 30 to perform signal transmission, and when not receiving a transmission instruction from the operation unit 36, the first communication unit 30 causes the signal to be received. Here, in the first communication unit 30, voice communication by PTT is executed. Therefore, the signal transmitted from the first communication unit 30 includes an audio signal received by the microphone provided in the call unit 38. On the other hand, the signal received by the first communication unit 30 includes an audio signal to be output from a speaker provided in the call unit 38.

Thus, in the wireless terminal device 20 that is the mobile wireless terminal device 10 and the portable wireless terminal device 12, control is performed to switch the first communication unit 30 between the sleep state and the operating state. In the following, in order to further improve the accuracy of the control, that is, to further suppress the occurrence of a situation in which the first communication unit 30 of the mobile wireless terminal device 10 and the first communication unit 30 of the portable wireless terminal device 12 are simultaneously in an operating state. An additional process will be described. The additional processing is indicated as (1) to (3), and will be described in the order of (1) to (3).

(1) When switching the first communication unit 30 from the hibernation state to the operation state, the control unit 34 determines to switch to the operation state and then delays the first communication unit 30 for a certain period while remaining in the hibernation state. That is, when switching from the state in which the reception unit 44 makes reception unexecuted to the state in which the reception unit 44 performs reception, the state in which the reception unit 44 makes reception non-execution continues for a certain period. On the other hand, when switching the first communication unit 30 from the operating state to the dormant state, the control unit 34 immediately executes the switch when determining to switch to the dormant state. As a result of such processing, the first communication unit 30 of the mobile wireless terminal device 10 and the first communication unit 30 of the portable wireless terminal device 12 both enter a dormant state, but both are in an operating state. The occurrence of this situation is suppressed.

(2) Here, it is assumed that the communication in the second communication unit 32 is a radio wave beacon. The acquisition unit 40 in FIG. 2 has a GPS (Global Positioning System) positioning function, and acquires position information of the wireless terminal device 20. Since a well-known technique should just be used for the positioning by GPS, description is abbreviate | omitted here. The acquisition unit 40 outputs the acquired position information to the control unit 34. The control part 34 makes the 2nd communication part 32 alert | report a 2nd identifier and position information with an electromagnetic wave beacon. Further, the second communication unit 32 receives a radio beacon signal notified from another wireless terminal device 20. The received signal includes the second identifier and position information of the other wireless terminal device 20. The second communication unit 32 outputs the second identifier and the position information included in the received signal to the control unit 34.

As in the past, the control unit 34 checks whether or not the second identifier included in the signal received by the second communication unit 32 matches the “registered second identifier” stored in the storage unit 42. To do. If they match, the control unit 34 calculates the distance based on the position information acquired by the acquisition unit 40 and the position information included in the signal received by the reception unit 44. Moreover, the control part 34 confirms whether distance is below a threshold value. Here, the threshold value is set to be shorter than the radio beacon can be transmitted. When the distance is equal to or smaller than the threshold, the control unit 34 determines that the other wireless terminal device 20 is close, and when the distance is not equal to or smaller than the threshold, the other wireless terminal device 20 is not close. Is determined. As described above, even if the radio beacon signal can be received, the distance is confirmed, so that the possibility that both the mobile wireless terminal device 10 and the portable wireless terminal device 12 are determined to be close to each other is increased. As a result, the occurrence of a situation where both of these are in an operating state is suppressed.

Note that this threshold value may be set according to the usage status of the user's mobile wireless terminal device and portable wireless terminal device. For example, if the user has a distance between the user and the mobile wireless terminal device within 5 m, the business wireless function of the mobile wireless terminal device is used, and if the distance is 5 m or longer, the business wireless function of the portable wireless terminal device is used. In such a situation, this threshold value is set to 5 m. As a result, the business wireless function of the wireless terminal device used by the user is activated, and convenience is improved.

(3) Here, it is assumed that communication in the second communication unit 32 is near field communication. The second communication unit 32 performs interconnection with another wireless terminal device 20 to which the second identifier stored in the storage unit 42 is assigned. Since a known technique may be used for the interconnection, description thereof is omitted here. When the mutual connection is established, the second communication unit 32 reports the establishment to the control unit 34.

The control unit 34 confirms whether or not the interconnection in the second communication unit 32 has been established. When the interconnection is established, the control unit 34 determines that the other wireless terminal device 20 is in proximity, and when the interconnection is not established, the other wireless terminal device 20 is not in proximity. judge. When the interconnection is established, synchronization between the mobile wireless terminal device 10 and the portable wireless terminal device 12 is also established. Therefore, it is determined that the mobile radio terminal apparatus 10 and the portable radio terminal apparatus 12 are close to each other, and the occurrence of a situation where both of them are in an operating state is suppressed.

This configuration can be realized in terms of hardware by a CPU, memory, or other LSI of any computer, and in terms of software, it can be realized by a program loaded in the memory, but here it is realized by their cooperation. Draw functional blocks. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

The operation of the communication system 100 configured as above will be described. FIG. 4 is a flowchart showing a processing procedure when the mobile radio terminal apparatus 10 is turned on. The first communication unit 30 enters a dormant state (S10). The second communication unit 32 searches for the portable wireless terminal device 12 (S12). When the portable wireless terminal device 12 is close (Y in S14), the first communication unit 30 is in an operating state (S16). On the other hand, when the portable wireless terminal device 12 is not in close proximity (N in S14), the first communication unit 30 enters a dormant state (S18). If the power is not turned off (N in S20), the process returns to step 12. If a power-off operation is performed (Y in S20), the process is terminated.

FIG. 5 is a flowchart showing a processing procedure when the portable wireless terminal apparatus 12 is turned on. The first communication unit 30 enters a dormant state (S30). The second communication unit 32 searches for the mobile wireless terminal device 10 (S32). When the mobile wireless terminal device 10 is in close proximity (Y in S34), the first communication unit 30 enters a dormant state (S36). On the other hand, when the mobile wireless terminal device 10 is not in proximity (N in S34), the first communication unit 30 enters an operating state (S38). If the power-off operation is not performed (N in S40), the process returns to step 32. If a power-off operation is performed (Y in S40), the process is terminated.

FIG. 6 is a flowchart showing a determination procedure performed by the wireless terminal device 20. The second communication unit 32 receives a signal from another wireless terminal device 20 (S50), and extracts a second identifier from the received signal (S52). When the extracted second identifier matches the second identifier stored in the storage unit 42 (Y in S54), the control unit 34 determines that the proximity is approaching (S56). When the extracted second identifier does not match the second identifier stored in the storage unit 42 (N in S54), the control unit 34 determines that it is not in proximity (S58).

FIG. 7 is a flowchart showing another determination procedure performed by the wireless terminal device 20. The second communication unit 32 receives a signal from another wireless terminal device 20 (S70), extracts a second identifier from the received signal (S72), and extracts position information from the received signal (S74). . The acquisition unit 40 acquires position information of the wireless terminal device 20 (S76). The control unit 34 derives a distance from the acquired position information and the extracted position information (S78). When the extracted second identifier matches the second identifier stored in the storage unit 42 (Y in S80), if the distance is equal to or smaller than the threshold value (Y in S82), the control unit 34 determines that it is close. (S84). When the extracted second identifier does not match the second identifier stored in the storage unit 42 (N in S80), or when the distance is not equal to or less than the threshold value (N in S82), the control unit 34 determines that it is not in proximity. (S86).

FIG. 8 is a flowchart showing still another determination procedure by the wireless terminal device 20. When the connection by the near field communication in the 2nd communication part 32 is established (Y of S100), the control part 34 determines with proximity | contact (S102). When the connection by the short-range wireless communication in the second communication unit 32 is not established (N in S100), the control unit 34 determines that it is not in proximity (S104).

According to the present embodiment, whether or not to perform reception is determined depending on whether or not another wireless terminal device having the same first identifier is close to the wireless terminal device. If the operations of the wireless terminal device and the wireless terminal device are reversed, it is possible to prevent the same first identifier from being used simultaneously. Moreover, since it is suppressed that the same 1st identifier is used simultaneously, generation | occurrence | production of inconsistency in a communication system can be suppressed. Moreover, since the occurrence of inconsistency in the communication system is suppressed, the same first identifier can be used between wireless terminal devices configured separately.

In addition, since the commercial radio is controlled to be in an active state or a dormant state based on the second identifier received in short-range wireless communication having a shorter transmission distance than the commercial radio, other terminals Control according to whether or not the devices are close to each other can be executed. Moreover, since it is used whether the 2nd identifier contained in the received signal is the same as the 2nd identifier registered previously, it can be determined easily whether it adjoins. Moreover, since it is used whether the 2nd identifier contained in the received signal is the same as the 2nd identifier registered previously, it can be determined correctly whether it adjoins.

Also, since it is determined whether or not they are close based on the distance, the determination accuracy can be improved. Further, by shortening the threshold value to be compared with the distance, it is possible to suppress the occurrence of a situation where the proximity determination result differs between the mobile wireless terminal device and the portable wireless terminal device. Further, since it is determined whether or not they are close based on the establishment of the interconnection, the determination accuracy can be improved. In addition, since it is determined whether or not they are close to each other based on the establishment of the mutual connection, it is possible to suppress the occurrence of a situation where the determination results of proximity differ between the mobile wireless terminal device and the portable wireless terminal device. In addition, when switching from the hibernation state to the operation state, the operation is kept in the hibernation state for a certain period of time, so that it is possible to suppress the occurrence of a situation in which both the mobile radio terminal device and the portable radio terminal device are in the operation state.

(Example 2)
Next, Example 2 will be described. As in the first embodiment, the second embodiment is a communication system including a plurality of wireless terminal devices and a base station device, and a first identifier common between the mobile wireless terminal device and the portable wireless terminal device The present invention relates to a communication system using. In the first embodiment, the mobile wireless terminal device and the portable wireless terminal device are associated with each other on a one-to-one basis. On the other hand, in the second embodiment, a plurality of portable wireless terminal devices are associated with one mobile wireless terminal device. Each portable wireless terminal device is assigned a different first identifier, and the mobile wireless terminal device uses one of the first identifiers assigned to each portable wireless terminal device.

More specifically, when one of a plurality of portable wireless terminal devices and the mobile wireless terminal device are close enough to perform short-range wireless communication, the mobile wireless terminal device Using the first identifier assigned to the device, business radio is executed. At that time, the portable wireless terminal device in the vicinity of the mobile wireless terminal device suspends the execution of commercial wireless. The wireless terminal device 20 according to the second embodiment is of the same type as that in FIG. 2, and here, the difference from the first embodiment will be mainly described.

FIGS. 9A to 9B show the configuration of the communication system 100 according to the second embodiment.

In particular, the receiving unit 44 of the first communication unit 30 receives a signal on the commercial radio by using a first identifier having a different value for each portable wireless terminal device 12.

In the second embodiment, the content stored in the storage unit 42 differs depending on the mobile wireless terminal device 10 and the portable wireless terminal device 12. Here, after the storage unit 42 of the mobile wireless terminal device 10 is described, the storage unit 42 of the portable wireless terminal device 12 will be described. The storage unit 42 of the mobile radio terminal device 10 stores the first identifier and the second identifier of the mobile radio terminal device 10 and, for a plurality of associated portable radio terminal devices 12, a portable radio terminal device. For every twelve, the second identifier and the first identifier are stored in association with each other.

FIG. 10 shows a data structure of a database stored in the storage unit 42 according to the second embodiment. “First identifier” and “second identifier” indicate values given to the mobile radio terminal apparatus 10. Here, the value of the “first identifier” is variable and is “not set”. “Registered first identifier (part 1)” and “Registered second identifier (part 1)” are a first identifier and a second identifier assigned to the associated first portable wireless terminal device 12, respectively. Show. “Registered first identifier (part 2)” and “Registered second identifier (part 2)” indicate the first identifier and the second identifier assigned to the second portable wireless terminal device 12 associated with each other. Show. The same applies to “registered first identifier (part 3)” and “registered second identifier (part 3)”. Returning to FIG.

The storage unit 42 of the portable wireless terminal device 12 stores the first identifier and the second identifier assigned to the portable wireless terminal device 12 as in the first embodiment. Furthermore, the storage unit 42 also stores a second identifier assigned to the associated mobile radio terminal apparatus 10.

FIGS. 11A to 11C show the data structure of the database stored in the storage unit 42 according to the second embodiment. FIG. 11A shows a data structure of a database stored in the storage unit 42 of the first portable wireless terminal device 12a, and FIG. 11B is stored in the storage unit 42 of the second portable wireless terminal device 12b. Shows the data structure of the database. FIG. 11C shows a data structure of a database stored in the storage unit 42 of the third portable wireless terminal device 12c. For example, in FIG. 11A, the first identifier “501” and the second identifier “21” assigned to the first portable wireless terminal device 12a are stored. The same applies to FIGS. 11B to 11C. Further, in common with FIGS. 11A to 11C, the second identifier “10” given to the mobile radio terminal apparatus 10 is also stored as “registered second identifier”. Returning to FIG.

In the second embodiment, the processing in the control unit 34 differs depending on the mobile wireless terminal device 10 and the portable wireless terminal device 12. Here, the control unit 34 of the mobile wireless terminal device 10 will be described, and then the control unit 34 of the portable wireless terminal device 12 will be described. The control unit 34 of the mobile radio terminal apparatus 10 transmits, to the second communication unit 32, “registered second identifier (part 1)” to “registered second identifier (part 3)” stored in the storage unit 42. The portable wireless terminal device 12 having “” is searched by short-range wireless communication. The second communication unit 32 reports the search result for each second identifier of the portable wireless terminal device 12 to the control unit 34 as needed. The control unit 34 performs control so that the first communication unit 30 is in an operating state or a dormant state according to the notification content from the second communication unit 32. Further, the control unit 34 sets the content of the “first identifier” in the storage unit 42 when the first communication unit 30 is in an operating state.

This process will be described more specifically. When the portable wireless terminal device 12 having any registered second identifier is in proximity to the notification content from the second communication unit 32, the control unit 34 The registered first identifier corresponding to the registered second identifier is acquired from the storage unit. Further, the control unit 34 causes the storage unit 42 to store the acquired registered first identifier as the first identifier of the mobile wireless terminal device 10. When a plurality of portable wireless terminal devices 12 are close to each other in the notification content, the control unit 34 selects any one of them, for example, the second identifier having the smallest value, and executes the above-described processing. Furthermore, the control unit 34 changes the first communication unit 30 to the operating state. As a result, when any one of the portable wireless terminal devices 12 is close to the mobile wireless terminal device 10, the control unit 34 uses the first identifier corresponding to the second identifier assigned to the portable wireless terminal device 12. In addition, using the first identifier stored in the storage unit 42, the reception unit 44 performs reception.

On the other hand, when the first communication unit 30 is in an operating state, the control unit 34 in the notification content from the second communication unit 32 has the second identifier portable wireless terminal device 12 corresponding to the already set first identifier. If is close, continue setting. On the other hand, in the notification content from the second communication unit 32, the control unit 34, when the portable wireless terminal device 12 having the second identifier corresponding to the already set first identifier is not in proximity, the first communication unit 30 Is changed to a dormant state, and the first identifier of the storage unit 42 is set to “not set”.

The control unit 34 of the portable wireless terminal device 12 executes the same processing as in the first embodiment. Therefore, when the mobile wireless terminal device 10 is close to the portable wireless terminal device 12, the control unit 34 causes the mobile wireless terminal device 10 to use the first identifier stored in the storage unit 42 and receive it. The unit 44 is made not to execute reception.

The first communication unit 30 enters a dormant state (S120). The second communication unit 32 searches for the portable wireless terminal device 12 (S122). When the first communication unit 30 is in a dormant state (Y in S124), if the portable wireless terminal device 12 is close (Y in S126), the control unit 34 sets the first identifier of the terminal itself (S128). ). The 1st communication part 30 will be in an operation state (S130). On the other hand, when the portable wireless terminal device 12 is not close (N in S126), step 128 and step 130 are skipped.

If the first communication unit 30 is not in the dormant state (N in S124), and the portable wireless terminal device 12 having the second identifier corresponding to the first identifier of the terminal itself is not in close proximity (N in S132), the first communication unit 30 enters a dormant state (S134). The control unit 34 changes the first identifier of its own terminal to “unset” (S136). If the portable wireless terminal device 12 having the second identifier corresponding to the first identifier of the own terminal is in close proximity (Y in S132), step 134 and step 136 are skipped. If the power-off operation is not performed (N in S138), the process returns to step 122. If the power is turned off (Y in S138), the process is terminated.

FIG. 13 is a flowchart showing a processing procedure when the portable wireless terminal device 12 is turned on. The first communication unit 30 enters a dormant state (S150). The second communication unit 32 searches for the mobile wireless terminal device 10 (S152). When the mobile wireless terminal device 10 is close (Y in S154), the second communication unit 32 communicates with the mobile wireless terminal device 10 (S156). If the 1st communication part 30 of the mobile radio | wireless terminal apparatus 10 is a dormant state (Y of S158), the 1st communication part 30 will be in a dormant state (S160). On the other hand, if the first communication unit 30 of the mobile wireless terminal device 10 is not in the dormant state (N in S158), step 160 is skipped. When the mobile wireless terminal device 10 is not in close proximity (N in S154), the first communication unit 30 enters an operating state (S162). If the power is not turned off (N in S164), the process returns to step 152. If the power is turned off (Y in S164), the process is terminated.
