Description

  The present invention relates to an incoming call notification system that suppresses power consumption of a smartphone.

  There is a SIP client application as an application for using a smartphone as a handset of a fixed telephone. A smartphone is a terminal connected to a network through 3G (3rd Generation), LTE (Long Term Evolution), or WiFi (Wireless Fidelity). For example, an Android terminal with Android OS 2.2 or higher, an iPhone with iOS 3.0 or higher, or an iPod touch of 4th generation or higher.

  The SIP client application is an application that operates on a smartphone, and accommodates a smartphone as an SIP terminal in a SIP control unit built in a line termination device such as a home gateway. Make it possible. SIP is an acronym for Session Initiation Protocol and is pronounced “ship”. Hereinafter, the term “SIP” may be omitted, and only the term “client application” means “SIP client application”.

  The smartphone on which the SIP client application operates is registered in the SIP control unit as a slave unit of the extension telephone. When there is an incoming call, the SIP control unit transmits a signal indicating the incoming call to the client application on the smartphone. The client application that receives the incoming signal presents the incoming call to the user, and the user starts a call. In order for the client application on the smartphone to constantly receive a signal, it is necessary to make the client application resident on the smartphone.

  In addition to the method of allowing the SIP client application to reside on the smartphone, there is a push notification technique as a method for the smartphone to receive incoming information. Push notification is a method in which the system side actively acquires incoming information in cooperation with an external server and notifies a smartphone user. By using the push notification, it is possible to know the update of the incoming call information even if the user does not work. This push notification makes it possible to receive information in real time.

  In order to use push notification in Android OS, there is a method of using a push notification distribution server (for example, Non-Patent Document 1: Cloud to Device Messaging (C2DM)). In order to use push notification in iOS, there is a method of using Apple Push Notification Service (APNs) (Non-patent Document 2).

  When a smartphone is used as an extension handset for a fixed telephone in a home, for example, as described above, it is necessary to make the SIP client application resident on the smartphone. In this case, there is a problem that the power consumption increases because the client application always operates. A service using a push notification distribution server is provided only for a smartphone that communicates with an application server on a network. That is, the SIP client application that uses the push notification distribution server is not serviced for fixed telephones.

  Therefore, conventionally, when a smart phone is used as, for example, an extension handset for a fixed telephone in a home, it is necessary to make a client application resident and there is a problem that power consumption of the smart phone becomes excessive.

  The present invention has been made in view of such problems, and even when a smartphone is used as, for example, a handset for an extension of a fixed telephone in a home, an incoming call notification system capable of suppressing an increase in power consumption of the smartphone. And a line termination device.

Incoming notification system of the present invention includes a network, a push notification delivery server connected to the network, the network unit is connected to the end of the line of which is connected to the network fixed phone, a smart phone to be connected to the network It consists of. The line termination device includes a SIP control unit and an incoming call notification unit. The SIP control unit performs call control for establishing, changing, or disconnecting a session necessary for communication on the network. Incoming call notification section, the solid response to the incoming call notification to the constant phone, a message transmission request including the date and time of the registration ID and incoming notification SIP client application on a smart phone, and outputs the push notification delivery server. The push notification delivery server stores the registered ID to the database, to receive a message transmission request with respect smartphone corresponding to the registration ID in the message transmission request stored in the database, to fixed telephone Notify incoming calls.

  According to the incoming call notification system of the present invention, the SIP client application installed in the smartphone is activated in synchronization with the incoming call by providing the incoming call notification unit serving as the SIP client inside the line terminating device of the fixed telephone. It becomes possible to do. As a result, the SIP client application can be prevented from always starting, and the power consumption of the smartphone can be suppressed. This effect can be achieved without making any changes on the network by using the line termination device of the present invention.

  Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals are given to the same components in a plurality of drawings, and the description will not be repeated.

  FIG. 1 shows a system configuration example of an incoming call notification system 100 of the present invention. The incoming call notification system 100 includes a line termination device 110, a smartphone 120, a network 130, and a push notification distribution server 140. The push notification delivery server 140 is a server in which the above-described Cloud to Device Messaging (C2DM) and Apple Push Notification Service (APNs) are implemented, and is configured by conventional technology. As described above, the smartphone 120 is also a terminal connected to 3G or WiFi, and is configured with conventional technology. The network 130 is a conventional network line network. It may be a telephone network that operates with an IP address, an optical telephone network, or the like. In this embodiment, the new part is the line termination device 110. In FIG. 1, the notation of the fixed telephone connected to the line terminating device 110 is omitted. Hereinafter, the explanation will be focused on the new part.

  The line terminating device 110 includes a SIP control unit 111 and an incoming call notification unit 112. The SIP control unit 111 is connected to the network 130 and performs call control such as generation / change / disconnection of a session necessary for communication.

  The incoming call notification unit 112 stores the registration ID of the SIP client application on the smartphone 120 in the database, and outputs a message transmission request including the registration ID to the push notification distribution server 140 in response to the incoming call notification to the fixed telephone. . Here, the registration ID of the SIP client application is periodically transmitted from the push notification distribution server 140. That is, the registration ID of the smartphone 120 is registered in advance in the database of the push notification distribution server 140 through the public line. The registration ID is an individual ID that can identify the smartphone 120 such as account information of an email address, for example. This individual ID is stored in the incoming call notification unit 112 when periodically transmitted from the push notification distribution server 140. The operation of registering the registration ID of the smartphone 120 in the database of the push notification distribution server 140 is a conventional technique.

[Operation sequence]
FIG. 2 shows an operation sequence of the incoming call notification system 100 and will be described. The registration ID of the smartphone 120 used as an extension telephone will be described on the assumption that it has already been registered in the push notification distribution server 140 in the above-described procedure.

  For example, an incoming call to the fixed telephone is input to the line terminating device 110 via the network 130 which is an optical telephone line network (step S1). The SIP control unit 111 of the line terminating device 110 notifies the incoming call notification unit 112 of the incoming call (step S2). The notification of the incoming call is, for example, a session corresponding to the INVITE message described in Reference Document 1 “Takashi Takeshita et al.,“ Mastering TCP / IP Introduction ”Ohm, ISBN978-4-274-06677-1, pp.295-296”. It is a call to start.

  The incoming call notification unit 112 transmits a message transmission request including the registration ID of the smartphone 120 already stored in response to the incoming call notification and the date and time of the incoming call notification to the push notification distribution server 140 via the SIP control unit 111. (Step S3). The push notification distribution server 140 is fixed for each service company that provides the SIP client application, and its URL (Uniform Resource Locator) is stored in the SIP control unit 111 in advance.

  In response to the message transmission request from the line termination device 110, the push notification distribution server 140 transmits a message to the smartphone 120 having the registration ID in the message (step S4). The content of the message transmission is the same as the message transmission request.

  The incoming call synchronization activation unit 121 in the smartphone 120 compares the above incoming date and time included in the message from the push notification delivery server 140 with the time of the clock inside the smartphone 120 (step S5). If the time difference between the incoming date and time and the time of the clock is less than a predetermined time (for example, 1 minute), a registration application for starting the registration process of the SIP client is made to the line terminating device 110 (step S6). Application for registration is done by sending a password. This predetermined time is determined in advance by the user assuming the maximum time width during which the communication partner continues calling. The time width can be freely set by the user in the SIP client application.

  When the SIP control unit 111 receives a registration application with a password from the smartphone 120, the SIP control unit 111 authenticates the match with the password stored in advance corresponding to the smartphone 120, and returns the authentication result to the smartphone 120 (step S7). If the authentication of the authentication result can be confirmed (step S8), the smartphone 120 determines that the registration is successful and establishes a session with the line termination device 110 (step S9). The session here means from the start to the end of one call of an extension call in which the smartphone 120 and the line termination device 110 are connected by, for example, a wireless LAN. After the session is established, the user starts an extension call with the fixed telephone via the wireless LAN or the cable (step S10).

  If the time difference between the incoming date and time and the clock time is greater than or equal to a predetermined time (for example, 1 minute) (more than the predetermined time in step S5), or if the authentication result is unauthenticated (No in step S8), there is an incoming call However, a registration failure signal is output to inform the user that the extension call has not been made (step S11). When a registration failure signal is output, for example, the SIP client application performs a process of displaying the incoming time on the display unit and notifying the user.

  According to the incoming call notification system 100 described above, the incoming call notification unit 112 serving as a SIP client is provided inside the line terminating device 110 of the fixed telephone network so that it can be installed on the smartphone in synchronization with the incoming call of the fixed telephone. The SIP client application can be started, and the SIP client application can be prevented from always starting. As a result, an increase in power consumption of the smartphone can be suppressed. That is, by providing the incoming call notification unit 112 inside the line terminating device 110, it is possible to push-distribute incoming calls from the fixed telephone to the smartphone 120. These effects can be achieved without changing the smartphone 120 and the push notification delivery server 140 on the network.

[Modification]
In the above-described embodiment, the example in which the SIP control unit 111 and the incoming call notification unit 112 are provided in the line terminating device 110 has been described. The incoming call notification device 112 ′ may be configured with separate housings. In this case, by registering the IP address, user name, and password of the SIP control device 111 ′ in the incoming call notification device 112 ′, the present invention can be used by using the existing SIP control device 111 ′. FIG. 3 shows an example of the functional configuration of the line terminating device 110 ′ in which the SIP control device 111 ′ and the incoming call notification device 112 ′ are configured in separate housings.

  The SIP control device 111 ′ is the same functional configuration unit as the SIP control unit 111 described above, but is denoted by 111 ′ because it is independent in a separate casing. Registration applications and incoming notifications exchanged between the SIP control device 111 'and the incoming notification device 112' are transmitted, for example, by a single LAN cable. That is, the SIP control device 111 ′ and the incoming call notification device 112 ′ are connected by a signal line. For connection, it is necessary to register the IP address, user name, and password of the SIP control device 111 ′ in the incoming call notification device 112 ′. Registration is performed by the SIP control unit registration means 1120 described below.

  FIG. 4 shows an example of the functional configuration of the incoming call notification device 112 ′. The operation flow is shown in FIG. The incoming call notification device 112 ′ includes a SIP control unit registration unit 1120, a database 1130, an automatic message transmission unit 1140, and a control unit 1150. The SIP control unit registration means 1120 stores in the database 1130 the IP address, user name, and password of the SIP control device 111 ′ input by the user from a personal computer (not shown) connected to the incoming call notification device 112 ′ via a LAN cable or the like. (Step S1121). At the same time, it sends its own IP address to the SIP control device 111 'to apply for registration (step S1122). This registration application is accepted by the SIP control device 111 ′ if the communication error between the SIP control unit registration means 1120 and the SIP control device 111 ′ is less than the registration limit number of SIP control devices 111 ′. The database 1121 also stores the registration ID and password of the smartphone 120 that are periodically sent from the push notification distribution server 140 via the SIP control device 111 ′. In addition, the description of the operation step (FIG. 5) which registers the registration ID etc. of the smart phone 120 which is input from the SIP control device 111 ′ and stored in the database 1130 via the SIP control unit registration unit 1120 is omitted. Registration may be performed once at the first connection.

  The automatic message transmission means 1140 responds to the incoming call to the fixed telephone notified from the SIP control device 111 ′, and includes a message transmission request including the registration ID of the smartphone registered as the extension telephone and the date and time of the incoming call notification. Is generated (step S1141). Then, the message transmission request is transmitted to the push notification distribution server 140 via the network 130 (step S1142). The control unit 1150 determines whether the notification is an incoming call notification or a user input (step S1150). If the target IP address has already been registered, it may be judged as an incoming call notification, and if it has not been registered, it may be judged as a registration application from the user.

  FIG. 6 shows an operation sequence of this modification. Steps S1121 and S1122 described above correspond to step S0 in FIG. Further, step S1142 described above corresponds to step S3 in FIG. The processing after step S3 is exactly the same as in FIG. In other words, the same effects as those of the first embodiment can be obtained even when the line terminating device 110 ′ in which the SIP control device 111 ′ and the incoming call notification device 112 ′ are configured by separate housings is used.

  In addition, although the example in which the IP address, user name, and password of the SIP control device 111 ′ input by the user are input from the personal computer has been described, the smartphone 120 and the line termination devices 110 and 110 ′ are connected by a LAN cable or the like. Such information may be input from the smartphone 120.

  Moreover, although the case where the smart phone 120 is used as a handset of a fixed telephone in the home has been described as an example, the incoming call notification system and the line termination device of the present invention can be used for an extension used in the office or in the office. Needless to say.

  Further, the processing described in the above apparatus may be executed not only in time series according to the description order, but also in parallel or individually as required by the processing capability of the apparatus that executes the processing.

  Each functional unit and means may be configured by executing a predetermined program on a computer, or at least a part of these processing contents may be realized by hardware.
