  Currently, a wireless LAN connection is generally used as a method of using a personally-owned smartphone as an internal extension telephone. In this method, an IP network and a wireless LAN access point (hereinafter referred to as AP) are required as the extension telephone network of the private branch exchange, and it is necessary to consider the data system and the voice system in designing the IP network.

  In addition to this, smartphones have various wireless and wired IFs, but wireless LANs are most suitable as IFs for private branch exchanges, and the current mainstream is connection by wireless LANs.

  Private branch exchanges have various options and built-in types, but most models can be connected to an IP network for extension telephones. However, although many companies use an IP network as a data communication network such as a PC or an Internet line, having an IP network and an AP in a private branch exchange for voice communication is as much as a data communication network. It has not spread.

  This is due to the difficulty in constructing networks such as voice and data system priority control, bandwidth, delay calculation, etc. in IP network design, resulting in voice quality degradation, SE costs, and diversion rate of existing assets. Many companies still use non-IP communication networks (hereinafter referred to as non-IP communication networks as legacy networks) for voice systems.

  In addition, there is a problem of a wireless environment when a smartphone is used in a wireless LAN, and a problem that a smartphone battery for a user with a high frequency of extension calls may not have one day.

  If the BYOD is not taken into account as an internal extension telephone, the PHS is a general wireless communication device. A wireless base station connected to an existing legacy network (hereinafter, a PHS wireless base station connected to a legacy network of an exchange extension is connected as a base unit), and various exchanges based on voice communication are connected. Service functions can be used. However, PHS communication has a fixed bandwidth of 64 kbps, making it difficult to perform large-capacity data communication. The PHS slave unit is also made based on voice calls, and the user interface such as the display unit is the old generation. The convenience of mobile phones is not as good as that of smartphones.

  The present invention has been made in view of the problems of the prior art, and an object thereof is to provide an adapter for connecting a smartphone to a PHS network of a private branch exchange.

  Hereinafter, a smartphone adapter that is connected to a smartphone and enables communication with the BS is simply referred to as an adapter.

  An adapter that communicates between a smartphone and a BS, the adapter having a CPU and a memory, and the CPU requests the application to download the application via the BS, downloads the application from the exchange, and the memory The downloaded application is stored, the CPU inquires of the smartphone about the presence of the application, the application stored in the memory is downloaded to the smartphone in response to the response that the application is not, and the PS after the application is started from the smartphone. -In response to the ID automatic assignment setting / login request, the CPU transmits the PS-ID automatic assignment setting / login request to the exchange via the BS, and responds to the transmitted PS-ID automatic assignment setting / login request. The extension number and PS-ID transmitted from the exchange are received, and the received extension number and PS-ID are received. To send to the smartphone.

  According to the present invention, a smartphone can be used as an extension terminal of a private branch exchange.

  Hereinafter, examples will be described with reference to the drawings.

  FIG. 1 is an example of a configuration diagram of a private branch exchange 101 that accommodates an extension terminal 110 in which an adapter is attached to the smartphone of this embodiment.

  Private branch exchange 101 includes main unit (CC) 106, extension telephone accommodation card 102, radio base station accommodation card 103, office line card 104, and leased line card 105. A public network 111 is connected to the office line card 104, and a private line network 112 is connected to the private line card 105. The BS 108 which is the PHS radio base station of the extension terminal 110 is accommodated in the radio base station accommodation card 103. The radio base station accommodation card 103 is a card that accommodates the BS 108 and is used when a call is made by the PHS slave unit 109.

  Since a smartphone generally does not have an IF for PHS wireless communication, communication with the BS 108 is not possible. Therefore, the adapter is connected to the smartphone, communication with the BS 108 is enabled via the adapter, and the exchange 101 is accommodated as an extension terminal.

  FIG. 2 is a schematic diagram of the external appearance of the adapter 120. The adapter 120 has a USB terminal 122 connected to the smartphone 124, a PHS antenna 121 for communicating with the BS 108, and an input terminal (adapter charging terminal) 123 from a charger. In the separate type, the USB cable 131 is used for the separate type. The smartphone 124 generally has a USB terminal 125 and an IF (lightning connector or the like) equivalent to the USB terminal 125.

  The adapter 120 includes a CPU for performing various processes, peripheral circuits such as a memory, a battery for power supply and a charging circuit and a connector for charging, the USB-IF, the PHS antenna-IF, and the PCM-ADPCM for audio. A hardware circuit (dedicated IC, FPGA, or the like) that performs conversion is provided. The CPU executes input / output processing with the smartphone 124 and transmission / reception processing with the BS 108 described below. The memory stores various data such as download data that accompanies execution of various processes by the CPU. In addition, as data, for example, a state where an application executed by the smartphone 124 is stored in a memory is referred to as an application being installed.

  Using FIG. 3, the communication delay amount between the case of the conventional PHS slave unit 109 and the case where the adapter 120 is attached to the smartphone 124 is compared. The amount of communication delay is an important evaluation item when the smartphone 124 is used as the extension terminal 110 of the private branch exchange 101 in which voice communication is a basic function because it directly leads to voice quality in the case of voice communication.

  The difference between using the PHS handset 109 and the smartphone 124 is the communication path from each to the BS 108, and the path from the BS 108 to the call destination (the extension telephone 107 or the external terminal 140) is the same. There is no.

  In the case of the PHS cordless handset 109, the main delay is PCM-ADPCM conversion, but currently, a dedicated IC, a dedicated IP-CORE of FPGA, etc. are used, and it is generally performed by pure hardware processing. The amount is about several hundred μsec.

  The main delay when the adapter 120 is attached to the smartphone 124 is that the delay due to USB transfer is about 1 msec, the PCM-ADPCM conversion is several hundred μsec, and the processing time (protocol conversion) in the adapter 120 is about several msec.

  In addition to this, A / D conversion for converting analog signals such as microphones and speakers, processing time of the PHS radio unit, and the like are communication delay amounts, but when using the PHS slave unit 109 and when using the smartphone 124. It is the same, and is not a factor that causes a difference in the communication delay amount.

  Therefore, when the communication delay amount is compared between the case where the PHS cordless handset 109 is used and the case where the extension terminal 110 with the adapter 120 attached to the smartphone 124 is used, the communication delay amount is several msec larger when the extension terminal 110 is used. Become.

  Usually, when the smartphone 124 is used as an extension terminal using a wireless LAN, the communication delay amount is about several tens to several hundreds msec due to RTP processing, network delay, and the like. Compared with this value, it is an order of about 1/100, and when it is said that it is a legacy quality (high quality) and IP quality (low quality) of general voice, it is a value that is sufficiently classified as legacy quality. (Reference: NTT voice quality evaluation method http://www.ntt.co.jp/qos/technology/sound/05_3.html).

  The operation of the adapter 120 will be described with reference to FIG. When the adapter 120 is connected to the smartphone 124 and used, a dedicated application (application software) is required for the smartphone 124 (hereinafter simply referred to as an application indicates a dedicated application for the adapter 120). The downloading method of the application is a method in which the owner of the smartphone 124 downloads from the download site 150 such as an app store for each individual, and automatically when the smartphone 124 is connected to the adapter 120 (without using the hands of the owner). There are two ways to do this.

  A method for downloading an application to the adapter 120, which is necessary for automatic download, will be described with reference to FIG. The application downloaded to the adapter 120 is installed in the exchange 101 (hereinafter simply referred to as an exchange means the exchange main body including the BS 108 and the main device (CC) 106 installed in the exchange 101). 1001). Before connecting the smartphone 124 and the adapter 120, the exchange 101 and the adapter 120 can communicate with each other (PHS connection) (1002).

  When the connection of the adapter 120 is confirmed to the exchange 101, the adapter 120 notifies the exchange 101 of an application download request (2000). Upon receiving the notification, the exchange 101 downloads the application to the adapter 120 (2001). The application is mounted on the adapter 120 by the above procedure (1003).

  The application VerUP (version upgrade) method will be described with reference to FIG. There are two VerUP timings, and in any case, it is first necessary to VerUP an application installed in the exchange 101.

  The first timing is the timing when the application of the exchange 101 is VerUP. The pre-VerUP application is installed in the adapter 120 (1004), and the pre-VerUP application is installed in the exchange 101 (1005). In this state, the adapter 120 and the exchange 101 are connected (PHS connection). (1002). In this state, when the application installed in the exchange 101 is VerUP (1006), the exchange 101 searches for all the connected adapters 120 (1007), and for all the connected adapters 120, An application Ver notification request is transmitted (2002). The adapter 120 that has received the Ver notification request transmits an application Ver notification to the exchange 101 (2003). The exchange 101 compares the Ver with the VerUP-installed application installed in itself (1008), and if the Ver of the application installed in the adapter 120 is old, the application is downloaded from the exchange 101 to the adapter 120 (2001). As a result, the application of the adapter 120 is VerUP (1009).

  The second timing is when the adapter 120 is out of service area or the power is turned off at the first timing, and is the timing (1002) when the adapter 120 is connected to the exchange 101. A Ver notification of the application is transmitted to the exchange 101 (2003). The exchange 101 that has received the Ver notification (2003) compares the Ver with the VerUP-installed application installed in itself (1008). If the Ver of the application installed in the adapter 120 is old, the exchange 101 transfers to the adapter 120. Download the application (2001). Thus, the application of the adapter 120 is VerUP (1009).

  At any timing, if the Vers match or the app of the adapter 120 is a newer Ver, the exchange 101 notifies the adapter 120 that the Ver of the app installed in the adapter 120 is the latest, and the new Do not download Ver apps.

  As described above, if the adapter 120 operates and is communicable with the BS 108, the adapter 120 is always loaded with the latest application.

  With regard to a method for downloading an application to the smartphone 124, an operation at the time of connection between the adapter 120 and the smartphone 124 after the second or subsequent automatic or manual operation will be described with reference to FIG.

  When the application is automatically downloaded to the smartphone 124, when the smartphone 124 is connected to the adapter 120 for the first time (USB connection) (1010), an application inquiry is made from the adapter 120 to the smartphone 124 (2010). The smartphone 124 notifies the adapter 120 that there is no application (2011). The adapter 120 downloads the application to the smartphone 124 (2012). When the download is completed (1011), the smartphone 124 activates the application (1012), and notifies the adapter 120 of the completion of activation of the application (2013).

  When the user of the smartphone 124 manually downloads the application to the smartphone 124, each user downloads the application from the download site 150 before connecting the adapter 120 to the smartphone 124. It connects to the download site 150 by carrier communication of the smartphone 124 (1014), transmits an application search and download request (2014), and downloads the application (2015, 1011).

  When the adapter 120 and the smartphone 124 are connected for the second time or later, the smartphone 124 that receives the application inquiry (2010) from the adapter 120 activates the application (1012) and notifies the adapter 120 of the Ver of the application (2016). If the Ver of the app of the smartphone 124 is older than the Ver of the app of the adapter 120, the adapter 120 downloads the app to the smart phone 124, and otherwise notifies that the Ver is the latest (2017).

  Whether the application is the latest or the application is old and downloaded from the adapter 120, the smartphone 124 activates the application (170) and notifies the adapter 120 of the completion of activation of the application (2013). The above is the method for downloading the application to the smartphone 124.

  The smartphone 124 with the adapter 120 attached is registered as the extension terminal 110 of the exchange 101 (hereinafter, the registration with the exchange 101 so that the smartphone 124 with the adapter 120 attached can be used as the extension terminal 110 of the exchange 101) The method will be described.

  In order to register the PHS slave unit 109 as an extension terminal of the exchange 101, an extension number and a unique number called PS-ID are registered in the exchange 101. The extension number is arbitrarily set according to the numbering plan of the exchange 101, but the PS-ID is a number assigned to each PHS slave unit 109.

  The adapter 120 with the PS-ID number (factory set) may be used, but the PS-ID is registered in the exchange 101 or the smartphone 124, and the adapter 120 needs to be registered with the PS-ID. And not. By eliminating the need to register the PS-ID in the adapter 120, it is not necessary to associate the smartphone 124 with the adapter 120, and any smartphone 124 can be used on any adapter 120. Convenience is improved.

  An example of data setting registered in the exchange 101 will be described with reference to FIG. In the data setting, the extension number and PS-ID, as well as the terminal type, group number, and the like are registered (command example “PSID” 160) as in the registration of the PHS slave unit 109.

  In order to improve the convenience of the user of the adapter 120, the PS-ID may be automatically given to the smartphone 124. Conversely, in order to identify the user of the adapter 120 and increase security, the PS-ID may be manually set for each smartphone 124 so that the smartphone 124 with no PS-ID set cannot be used. In order to be able to select the above-mentioned PS-ID assigning method, it is also set whether or not the PS-ID is automatically assigned as the data setting in the exchange 101 (command example “PSIDA” 161).

  The procedure up to login will be described with reference to FIGS. The case of PS-ID automatic assignment setting will be described with reference to FIG. “PSID” 160, “PSIDA” 161, etc. are set in the station data of the exchange 101, and the presence of automatic PS-ID assignment is set (1020). As described above, the application is activated when the adapter 120 is connected to the smartphone 124 (1012, 2013), and the initial screen 170 as shown in FIG. 12 is displayed. First, the user taps the PS-ID setting button 172. In response to the tap of the PS-ID setting button 172, the screen transits to a PS-ID setting screen 180 as shown in FIG. When “PS-ID automatic assignment” 181 is set to “automatic” on this screen (1021) and the “OK” button 183 is tapped, the PS-ID is automatically assigned, and the initial screen 170 is displayed again. When the login button 171 is tapped on the initial screen 170, the login operation starts. A login request by automatic PS-ID assignment is transmitted from the smartphone 124 to the exchange 101 via the adapter 120 (2020, 2021). The exchange 101 searches the station data for whether the PS-ID is automatically assigned or not, and if there is an unused PS-ID (1022). If there is an unused PS-ID, An extension number and PS-ID are notified. The extension number and PS-ID are notified to the smartphone 124 via the adapter 120 (2022, 2023), the smartphone 124 registers the extension number and PS-ID (1023), and displays the login success screen example 190 of FIG. 14 ( 1024).

  An example of login failure is shown in FIGS. FIG. 8 shows a case where there is no unused PS-ID in the station data of the exchange 101 when the login request is transmitted to the exchange 101 (1030). In this case, the exchange 101 sends a terminal registration failure reply to the adapter 120. Is notified to the smartphone 124 (2030, 2031).

  FIG. 9 shows a case where the station data of the exchange 101 is not set to automatic PS-ID assignment when the login request is transmitted to the exchange 101 (1041). In this case, the exchange 101 returns a terminal registration impossible reply. To the smartphone 124 via the adapter 120 (2030, 2031).

  FIG. 10 shows a case where the radio wave condition between the adapter 120 and the BS 108 is bad and the adapter 120 is out of service area. In this case, the adapter 120 notifies the smartphone 124 of the terminal registration failure reply (2031). Is always notified from the adapter 120 to the smartphone 124, and in this case, “out of service area” is displayed on the smartphone 124.

  If login fails, the login failure screen 192 of FIG. 14 is displayed in any case (1031), and the screen returns to the application activation screen 170. The screen transition is shown in FIG.

  The case of PS-ID manual assignment setting will be described with reference to FIG. First, “PSID” 160, “PSIDA” 161, etc. are set in the station data of the exchange 101, and no PS-ID automatic assignment is set (1040). As described above, the application is activated when the adapter 120 is connected to the smartphone 124 (1012, 2013), and the initial screen 170 as shown in FIG. 12 is displayed. When the user taps the PS-ID setting button 172, a transition is made to a PS-ID setting screen 180 as shown in FIG. On this screen, “PS-ID automatic assignment” 181 is set to “manual”, the PS-ID number is input 182 (1021), and the “OK” button 183 is tapped to set the PS-ID to manual assignment setting. The screen returns to the initial screen 170. By tapping the login button 171 on the initial screen 170, the login operation starts. A login request with a PS-ID notification is transmitted from the smartphone 124 to the exchange 101 via the adapter 120 (2050, 2051). The exchange 101 retrieves from the station data whether the PS-ID is set to be manually assigned or not, and if there is a registered PS-ID or whether the PS-ID is unused (1050). ). If the PS-ID notified by the search is usable, the extension number associated with the PS-ID is notified. The extension number is notified to the smartphone 124 via the adapter 120 (2052, 2053), the smartphone 124 registers the extension number, displays the login success screen example 190 of FIG. 14 (1051), and the login is completed (1024).

  The example of login failure in the case of manual setting of PS-ID is that the notified PS-ID is not registered, is already used even if it is registered, and the adapter 120-BS108 is set to automatically assign PS-ID. There may be cases where the radio wave condition is poor and you are out of service area. Since the operation sequence conforms to the operation at the time of automatic PS-ID assignment setting, description thereof is omitted. In either case, the login failure screen 192 of FIG. 14 is displayed, and the screen returns to the application activation screen 170. The above is the operation related to login.

  The initial setting of the smartphone 124 will be described with reference to an example of data exchange 101 station data setting in FIG. 6, a transition diagram in FIG. 15, and FIGS. 16 to 18.

  The adapter 120 realizes so-called BYOD in which the personally owned smartphone 124 is registered as an extension terminal of the private branch exchange 101 in the company, and security measures need to be taken into consideration. Therefore, it is possible to set whether to improve the convenience of the user or the security in the company by using the station data of the exchange 101, and the setting contents are notified when the smartphone 124 with the adapter 120 is logged in, and the smartphone 124 is initially set. I do.

  FIG. 6 shows an example of setting of the exchange 101 station data. In this example, among the functions of the smartphone 124, a setting is made for whether or not to restrict three items of the carrier wave, a wireless IF other than the carrier wave, and an app other than the app and the application related to the adapter 120 described later. In addition, it is possible to set whether or not the login can be continued when the setting cannot be set for the smartphone 124 (command example “ADPINI” 163).

  Since this setting is assumed to have different limits for each user, such as the job system and role of the adapter 120 user, it is possible to select whether to apply to all terminals, for each terminal, for each group, and to subdivide the data settings. And increase efficiency (parameter 1 of command example “ADPINI” 163).

  The initial setting procedure will be described with reference to FIG. 16 in the case where the login can be continued after the initial setting procedure, and FIG. First, “ADPINI” 163 and the like are set with the station data of the exchange 101, and initial setting registration for the smartphone 124 is performed (1060). After the login to the exchange 101 is completed (1024), the exchange 101 retrieves the initial setting contents of the logged-in terminal and retrieves whether there is a restriction (1061). To the smartphone 124 as an initial setting (2060, 2061).

  If there are restrictions from the received initial settings, the smartphone 124 performs those settings (1062), and the setting results of the items that have been set and items that cannot be set for the restricted items are exchanged via the adapter 120. 101 is notified (2062, 2063).

  The exchange 101 refers to the setting result performed by the smartphone 124 and the setting content of the station data to determine whether or not the login can be continued. When the login is possible (1063) (FIG. 16), the setting result of the terminal is logged. The continuation of login is notified to the smartphone 124 via the adapter 120 (2064, 2065). Upon receiving the login continuation notification, the smartphone 124 displays a screen such as the restriction setting notification screen 200 in FIG. 18 (1064), transitions to the standby screen 210 (1065), and becomes usable as an extension terminal (1066). ).

  When login cannot be continued (1070) (FIG. 17), a logout notification is sent to the smartphone 124 via the adapter 120 (2070, 2071). Upon receiving the logout notification, the smartphone 124 performs logout processing such as resetting the setting made in the initial setting notification, deleting the registered extension number, or deleting the assigned PS-ID in the case of PS-ID automatic assignment setting. (1071), a screen such as the restriction setting impossible screen 202 of FIG. 18 is displayed, a logout notification is notified to the exchange 101 via the adapter 120 (2072, 2073), and the initial screen 170 is returned. Upon receiving the logout notification, the exchange 101 deletes the issued PS-ID registration (1072), and the logout process of the smartphone 124 is completed (1073). The above is the initial setting procedure.

  Through the procedure so far, the smartphone 124 with the adapter 120 in the standby screen state can be used as an extension terminal of the exchange 101, and functions and services similar to those of the conventional PHS slave unit 109 can be used. is there.

  Functions similar to those of the conventional PHS cordless handset 109, such as outgoing / incoming call, call, hold, transfer, call control, call-related operations, out of service area, handover, roaming, button reception, character string display, position information, etc. Since there is no difference in the operation of the service except that the smartphone 124 and the adapter 120 communicate via USB connection and the adapter 120 performs protocol conversion, a description thereof will be omitted.

  Instead of the functions and services used in these conventional PHS slave units 109, since the terminal is a smartphone 124, it is possible to provide services that were difficult to realize with the conventional PHS slave units 109. This is described in Example 2.

  A procedure for ending BYOD of the smartphone 124, removing the adapter 120, and returning it to the private smartphone 124 will be described with reference to FIG.

  There are two logout methods: either tap the app end button on the app screen or remove the adapter 120 (1080). In any case, the smartphone 124 ends the application, and performs logout processing such as resetting the initial setting value, deleting the extension number, and deleting the PS-ID in the case of the PS-ID automatic assignment setting (1082).

  When the adapter 120 receives a logout notification (2072) from the smartphone 124 or detects a USB disconnection (1081) (1083), the adapter 120 notifies the switchboard 101 of logout (2073). At this time, if the radio wave is out of service or the like and communication with the BS 108 is not possible, a retry process is performed on the adapter 120 side until communication is possible.

  Upon receiving the logout notification, the exchange 101 deletes the issued PS-ID registration (1072), and the logout process of the smartphone 124 is completed (1073).

  The above is the logout procedure.

  According to this embodiment, when using a smart phone as an extension terminal of a private branch exchange (BYOD), by using this adapter, the private branch exchange can utilize the PHS network which is an existing legacy network, and the voice quality is the legacy network. Can achieve the same quality. Further, since the IF with the private branch exchange is a BS, the service function of the exchange equivalent to that of the existing PHS can be used.

  In this embodiment, not only the functions and services that can be used by the conventional PHS slave unit 109 but also the provision of a more convenient service when the terminal is a smartphone 124, an exchange system installed in a hospital. Will be described as an example.

  FIG. 20 is an example of a configuration diagram of an exchange system for a hospital facility in the second embodiment. In FIG. 20, the description of the components having the same functions as those already described with reference to FIG. 1 is omitted.

  As a user of the adapter 120 with the smartphone 124, the usage form of the nurse (220), doctor (221), and patient (222) is considered, and other systems include a hospital room (225), toilet (226), patient-owned ( 228), etc., a nurse call device 224 for accommodating a nurse call slave device, a nurse call accommodation card 223 for accommodating the nurse call device 224, a PC 230 such as an examination room used by a doctor, etc. There is an electronic medical record server 231 for the electronic medical record system linked with the PC 230 and the like, and a LAN-IF 229 of the exchange 101 connected to the data system IP network.

  First, it is necessary to download to the smartphone 124 an application for using the present system (hereinafter referred to as an adapter 120 related application) and data used for executing the adapter 120 related application.

  As an application example of the adapter 120 related application, the map information of the hospital is prepared on the application side, the position information such as simple coordinates is input, the map of the hospital is displayed, and where the coordinates are The function to display location information graphically, the hospital electronic medical record information format, and patient data are prepared on the app side, and the electronic data related to the patient is input in response to the input of information identifying the patient. For example, medical chart data is displayed.

  FIG. 21 shows a method in which the owner of the smartphone 124 manually obtains the adapter 120 related application from the download site 150 such as an app store for each individual. Connect to the download site from the smartphone 124 by carrier connection or the like (1014), search for an application related to the adapter 120, search for VerUP information, etc. (2080), and download to the smartphone 124 (2081, 1081).

  In addition, if there is a server etc. in the hospital and there is maintenance of IP network, AP, etc., it is also possible to download from the hospital server with a general IF that the smartphone 124 has. is there.

  As with the adapter 120-dedicated application, a method of downloading from the adapter 120 via the exchange 101 is also conceivable. However, there are various types of adapter 120-related applications, and when the application capacity is large, the PHS communication speed is high. Downloading may take a long time and may not be suitable for actual operation.

  FIG. 21 shows a method of downloading data necessary for the adapter 120 related application. The application related to the adapter 120 is activated (1082), connected to a necessary site by carrier connection or the like (1014) (2082), and data necessary for the application related to the adapter 120 is downloaded (2083, 1084).

  In this example, the data required for the adapter 120 related application is in the server in the hospital and the server is connected to the Internet, etc., or necessary for the adapter 120 related application to the location where it can be downloaded by the carrier connection of the smartphone 124 such as the cloud. This shows the case where there is correct data. However, since such data is not normally exposed to an open network outside the company, security measures such as encryption and passwords (1083) or download using the in-hospital LAN environment as described above is generally used. Is.

  As described above, the adapter 120-related application and the data necessary for the adapter 120-related application are specially created for each industry, and the contents, data amount, confidentiality, and the like are different. The download method shown in is just an example.

  An actual operation example will be described with reference to FIGS. FIG. 22 shows an example of a case where a doctor (221), a patient (222), or the like who uses the smartphone 124 with the adapter 120 sends a message to the nurse (220) who uses the smartphone 124 with the adapter 120.

  When a doctor (221), a patient (222), or the like performs a call operation from the smartphone 124, call information is notified to the exchange 101 via the adapter 120 (2090, 2091). Since the exchange 101 knows which extension terminal and from which BS 108 the call originates (1090), it adds the location information such as the extension number of the caller and the coordinates of the BS 108 installed and notifies the destination ( 2092, 2093). These amounts of information are comparable to the amount of information such as character strings transmitted to the conventional PHS cordless handset 109, and it is known that there is no problem in practical operation regarding the delay time of incoming calls even at the PHS communication speed. .

  The incoming notification with the sender information added is received via the adapter 120 to the nurse (220) smartphone 124. Upon receiving the caller information, the smartphone 124 inputs the caller information to the adapter 120 related application and displays the caller's location information on the map screen (252) or displays the caller's electronic medical record information on the screen ( 251) (an example screen is shown in FIG. 24).

  FIG. 23 is an example in which an incoming call enters the smartphone 124 with the adapter 120 in response to a call from the nurse call slave (225, 226, 228).

  There is an outgoing call mainly from the patient by the nurse call slave (225, 226, 228), and the nurse call device 224 is notified (2094). There are various types of nurse call handsets (225, 226, 228), but they are largely fixed types (225, 226) installed in hospital rooms, toilets, bathrooms, etc., and portable types carried by patients ( 228). In any case, the nurse call device 224 can manage information such as the position where the nurse call slave unit is installed or the wireless master unit 227 capturing the nurse call slave unit. Location information can be obtained (1100).

  The nurse call device 224 notifies the exchange 101 of a number (for example, an extension number) specifying the caller's nurse call slave and the location information of the caller (2095). The exchange 101 adds the received caller information and places an incoming call on the smartphone 124 of the nurse (220) via the adapter 120 (2092, 2093). The subsequent operation is the same as the sequence of the smartphones 124 with the adapter 120 in FIG.

  In this example, the nurse call slave unit (225, 226, 228) is associated with the caller information by the nurse call device 224, but the extension information of the specific information of the nurse call slave unit (225, 226, 228) Conversion or the like may be performed by the exchange 101.

  As described above, the nurse who receives the call can graphically obtain information such as what the caller is and where the caller is calling from. Thus, like the conventional PHS cordless handset 109, As compared with the case where the sender information is displayed only with a few character strings, the convenience is improved.

  The charging method of the adapter 120 and the convenience that the adapter 120 does not have unique information such as PS-ID will be described with reference to FIG. The adapter 120 is equipped with a battery and has an input terminal from the charger 260. The charger 260 is connected with AC100V261. The adapter 120 is mounted on the charger 260 to charge the adapter 120.

  Further, as described above, since the adapter 120 and the smartphone 124 are connected via USB, power can be supplied from the adapter 120 to the smartphone 124, and this function can prevent the smartphone 124 from running out of battery power.

  On the other hand, when the battery of the adapter 120 runs out, as shown in FIG. 25, an extra adapter 120 is required, but when the spare adapter 120 is prepared, the charge amount of the adapter 120 becomes empty. In this case, it is possible to continue use by simply replacing the spare adapter 120 that has been charged.

  From the above, regarding the battery exhaustion problem of the terminal, the conventional PHS cordless handset 109 was originally superior to the use of BYOD of the smartphone 124, but the battery was exhausted due to further abuse of the terminal while taking advantage of that advantage. It is possible to take measures.

  According to the above-described embodiment, by providing a dedicated application on a smartphone, it is possible to provide a user interface service that is more convenient than PHS. Further, the IF between the smartphone and the adapter is a wired connection by USB, and by installing a battery on the adapter side, it is possible to avoid running out of the smartphone battery.

The adapter has a USB communication function for connecting to a smartphone, and enables higher layer communication between the adapter and the smartphone. It also has a protocol conversion function between the two communications, and finally enables communication at a higher layer between the smartphone and the exchange.

  The adapter has a function to download an application for using the adapter on the smartphone from the exchange. When the adapter is connected to the smartphone via USB, it checks whether there is an application on the smartphone, Ver is the latest, etc. Has the function to download the latest app from the adapter to the smartphone.

  The adapter enables automatic distribution of PS-ID to a smartphone, assignment of an extension number, and the like automatically when the adapter is connected to the smartphone by setting the exchange. In addition, considering the security of BYOD, it is handled as a single extension terminal connected to the private branch exchange when the adapter is connected. For this reason, private use of smartphones, such as restricting startup and operations other than this adapter application, turning off carrier radio waves, etc. It is possible to place restrictions on

  When the smartphone is logged in to the exchange, it is possible to perform operations such as voice incoming and outgoing similar to normal PHS, and if there is an application created for each office on the smartphone, the exchange can be linked with them. Make it possible.

  The adapter is equipped with a battery and can be charged with a general power supply (AC100V) via a charger for the adapter, and the smartphone can be charged by a USB power supply function.

  When using a smartphone as an extension terminal of a private branch exchange (BYOD), by using an adapter, the private branch exchange can utilize the existing legacy PHS network, and the voice quality can be equivalent to that of the legacy network. . In addition, since the IF with the private branch exchange is a BS, the service function of the exchange equivalent to that of the existing PHS can be used. In addition, by installing a dedicated application on a smartphone, a user interface service that is more convenient than PHS can be provided.
