The server I / F69 constitutes a communication unit for forming a signal transmission line with the LAN 10. The server I / F 69 transmits the connection destination information (URL) stored in the connection destination information table 68 toward the mobile terminal 5.

Next, the operation of the nurse call system 1 will be described with reference to FIGS. 1, 4, and 5.
<Operation example 1: When talking on the public line network ("3G / LTE")>
When the patient X operates the call button provided on the grip handset 22 of the nurse call handset 2, a call signal is sent from the nurse call handset 2 to the corridor light 3. The corridor light 3 identifies the nurse call slave unit 2 for which the call button has been operated, and adds the identified slave unit ID of the nurse call slave unit 2 to the call signal. The call signal with the slave unit ID is transmitted from the corridor light 3 to the nurse call controller 6A via the LAN 10.

The controller CPU 61 of the nurse call controller 6A that has received the call signal with the slave unit ID reads the added slave unit ID and collates the slave unit ID with the patient information table 62a. The controller CPU 61 identifies a medical worker associated with the slave unit ID, refers to the mobile information table 62b, and collates the mobile ID of the medical worker. The collated patient information and the mobile ID are transmitted from the nurse call controller 6A to the pop-up server 6B and the nurse call master unit 4 together with a call signal with the slave unit ID.

The incoming call screen generation unit 66 of the pop-up server 6B generates an incoming call screen (pop-up screen) displayed on the screen 51 of the mobile terminal 5 based on the transmitted patient information, and accesses the generated incoming call screen. Generate a URL to do so. The generated incoming call screen is recorded in the incoming call screen recording unit 67. Further, the generated URL is stored in the connection destination information table 68. Further, the server CPU 65 of the pop-up server 6B identifies a predetermined mobile terminal 5 for transmitting a nurse call call signal based on the transmitted mobile ID.

The server I / F69 of the pop-up server 6B transmits the call signal to which the generated URL is added to the predetermined mobile terminal 5 specified by the server CPU 65 via the telephone exchange 7 and the local base station 9 by WiFi. To do. There is no limit to the number of mobile terminals 5 that can be specified, but in this example, a call signal with a URL is attached to the five mobile terminals 5 (see FIG. 1) carried by each nurse of the nurse team in charge of patient X. Is sent. The URL is added to the extension header of the call signal composed of, for example, the INVITE signal of the SIP protocol.

Each mobile terminal 5 that receives the ringing signal with the URL rings the ringing tone and accesses the incoming call screen recording unit 67 of the pop-up server 6B via the local base station 9 by WiFi based on the added URL. And request information. As a result, on the screen 51 of the mobile terminal 5, the incoming call screen 52 informing that the patient X is making a nurse call is displayed as, for example, a pop-up screen.

FIG. 4 shows an example of the incoming call screen 52. On the incoming call screen 52, the first operation unit 53 and the second operation unit 54 are displayed as touch areas. As described above, the mobile terminal 5 can use two communication methods (“3G / LTE” and “WiFi”) when talking to the nurse call slave unit 2. By touching the first operation unit 53, the public line network (“3G / LTE”) can be selected as the communication method. Further, by touching the second operation unit 54, a local communication network (“WiFi”) can be selected as the communication method.

Further, as shown in FIG. 4, patient identification information capable of identifying the patient X who made the nurse call is displayed on the patient display unit 55 of the incoming call screen 52. In this example, it can be identified that "Taro Suzuki" who is hospitalized in bed number 1 in Room 101 made a nurse call.

Further, on the incoming call screen 52, a first radio wave display unit 56 that displays the radio wave condition of 3G / LTE and a second radio wave display unit 57 that displays the radio wave condition of WiFi are displayed. In this example, the case where the radio wave condition of 3G / LTE and the radio wave condition of WiFi are equivalent is displayed.

It is assumed that, for example, the nurse A in charge of the nurses in charge of the team in charge first responds to the ringing tone of the mobile terminal 5 by answering the incoming call screen.
At the time of the answer operation, the nurse A can arbitrarily select whether to make a call using 3G / LTE or a call using WiFi. In this example, 3G / LTE is selected.
When the nurse A responds, the ringing tone of the mobile terminal 5 carried by the nurses other than the nurse A is stopped, and the incoming call screen 52 is hidden.

In conjunction with the response operation of the nurse A, the response signal with the mobile ID added is transmitted from the mobile terminal 5 of the nurse A to the public line network. A response signal with a mobile ID transmitted from the mobile terminal 5 is transmitted to the telephone exchange 7 via the public base station 8b and the public base station 8a.

The telephone exchange 7 identifies the answer signal with the mobile ID, and connects the communication path between the mobile terminal 5 of the nurse A and the nurse call slave unit 2 operated by the patient X.
As a result, the nurse call slave unit 2 and the mobile terminal 5 can talk using 3G / LTE.

(Modification example)
FIG. 5 shows another example of the incoming call screen 52.
As shown in FIG. 5, the first operation unit 53A and the second operation unit 54A of the incoming call screen 52 are arranged so that the area of the communication method having the better radio wave condition is displayed larger according to the radio wave condition. Is also good. In this example, as shown in the first radio wave display unit 56 and the second radio wave display unit 57, the 3G / LTE radio wave is in a better condition, so the first operation indicating the 3G / LTE communication method is shown. The area of unit 53A is displayed large.

In this case, the nurse A, who is the operator, touches and arbitrarily selects one of the operation units (first operation unit 53A and second operation unit 54A), and makes a call by the selected communication method. You can do it. Alternatively, when any part of the touch area 58 indicated by the broken line is touched, the communication method with better radio wave condition (3G / LTE communication method in this example) may be automatically selected. ..

Further, in FIGS. 4 and 5, the content of the patient identification information displayed on the patient display unit 55 may be divided into a plurality of layers and displayed. Specifically, in the first layer shown in FIGS. 4 and 5, the patient identification information in the second and subsequent layers may be displayed by touching the patient display unit 55. For example, in the second and subsequent layers, information such as the patient's medical treatment subject, rescue category, infectious disease, fall risk, nurse name in charge, doctor name in charge, drink information, dietary restrictions, address, telephone number, etc. will be displayed. You can do it.

<Operation example 2: When making a call over the local communication network ("WiFi")>
In the case of this example as well, the operation is the same as in the above operation example 1 until the patient X operates the call button of the nurse call slave unit 2 and the incoming call screen 52 is displayed on the screen 51 of the mobile terminal 5.

When the incoming call screen 52 is displayed, in this example, it is assumed that the nurse A first among the nurses of the team in charge selects WiFi on the incoming call screen shown in FIG. 4 and answers.
When the nurse A responds, the ringing tone of the mobile terminal 5 carried by the nurses other than the nurse A is stopped, and the incoming call screen 52 is hidden.

In conjunction with the response operation of the nurse A, the response signal with the mobile ID added is transmitted from the mobile terminal 5 of the nurse A to the local communication network. The mobile terminal 5 is connected to the telephone exchange 7 via WiFi via the local base station 9, and a response signal with a mobile ID transmitted from the mobile terminal 5 is transmitted to the telephone exchange 7.

The telephone exchange 7 identifies the answer signal with the mobile ID, and connects the communication path between the mobile terminal 5 of the nurse A and the nurse call slave unit 2 operated by the patient X.
As a result, the nurse call slave unit 2 and the mobile terminal 5 can talk using WiFi.

According to the nurse call system 1 having such a configuration, when a nurse call is received from a patient, it is decided whether to make a call via the public switched telephone network (3G / LTE) or the local communication network (WiFi). It can be selected in the mobile terminal 5. Therefore, the medical worker can select the call mode in consideration of the 3G / LTE radio wave condition of the mobile terminal 5 he / she carries and the WiFi radio wave condition. As described above, according to the nurse call system 1, it is possible to support the improvement of the call quality between the nurse call slave unit 2 and the mobile terminal 5.

In addition, for example, when the radio wave condition of 3G / LTE is good in the mobile terminal 5 carried by the user, the call mode by 3G / LTE that ensures high call quality should be set to be automatically selected. Is also possible. Alternatively, it is possible to compare the radio wave conditions of the two call modes and set so that the better call mode is automatically selected. Therefore, it is possible to further support the improvement of call quality.

Further, on the incoming call screen 52 displayed on the mobile terminal 5, the operation units 53 and 54 that can select the call mode are displayed, and the radio wave display units 56 and 57 that display the radio wave condition are displayed. Therefore, the medical worker can select the call mode by touch-operating the operation units 53 and 54 of the incoming call screen 52 while checking the radio wave condition of the mobile terminal 5 that he / she carries.

By the way, conventionally, it has not been possible to display the patient information managed in the nurse call system on the incoming call screen displayed at the time of receiving an incoming call via the external public line network. However, according to the nurse call system 1, the incoming call screen 52 is transmitted to the mobile terminal 5 via the local communication network (WiFi) constructed in the hospital. Therefore, the patient display unit 55 can be created using the patient information managed by the control unit 6 or the like installed in the hospital, and the patient display unit 55 can be included in the incoming call screen 52. Therefore, the medical staff can answer the incoming call after checking the information of the calling patient by looking at the incoming call screen 52 displayed on the mobile terminal 5. Further, in the configuration in which the patient identification information is displayed in the second and subsequent layers, it is possible to answer the incoming call after confirming more detailed patient information.

Further, an incoming call screen generation unit is used on hardware (pop-up server 6B) different from the nurse call controller 6A having a function of controlling communication between the nurse call slave unit 2, the nurse call master unit 4, and the mobile terminal 5. 66, an incoming call screen recording unit 67, and a server I / F 69 are provided. Therefore, it is not necessary to consider the limitation of specifications and design restrictions in the nurse call controller 6A, so that the degree of freedom in designing the functions provided in the pop-up server 6B is improved. For example, the number of mobile terminals 5 to which the incoming call screen 52 is transmitted can be set to a large number without being restricted by the existing nurse call controller.

The present invention is not limited to the above-described embodiment, and can be freely modified, improved, and the like as appropriate. In addition, the material, shape, size, numerical value, form, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

In the above embodiment, the case where there is a call from the nurse call slave unit 2 has been described. For example, even when the mobile terminal 5 is called from the nurse call master unit 4, the mobile terminal 5 also goes through the public line network. It may be possible to select a mode for making a call via a local communication network and a mode for making a call via a local communication network.
