<Embodiment 1: Overview>

This embodiment determines whether a call can be maintained at a predetermined quality during a call, and in the case of a determination result indicating that the call cannot be maintained, a mobile phone having a function of transmitting a notification mail stored in advance to a predetermined address Regarding terminals.
<Embodiment 1: Configuration>

  FIG. 1 is a conceptual diagram showing a portable terminal according to the present invention. First, it is assumed that the user moves to the basement during a call using the mobile phone (0101) (scene (a)). Then, the portable terminal (0101) detects that the call state has deteriorated. If it is determined that the predetermined call quality cannot be maintained, the held notification mail is transmitted to the call partner (0102) (scene (b)). The other party receives the notification mail, and confirms that there is a possibility that the current call is suddenly disconnected, the reason for the sudden disconnection, etc. (scene (c)).

  FIG. 2 shows a functional block diagram of the mobile terminal according to the present embodiment. The portable terminal (0200) includes a “communication unit” (0201), a “notification mail holding unit” (0202), a “calling side quality determination unit” (0203), and a “notification mail transmission control unit” (0204). And having.

  Note that each unit, which is a component of the present invention described in detail below, is configured by either hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, there are hardware configured by a CPU, a bus, a memory, an interface, a peripheral device, and the like, and software that can be executed on the hardware. As software, the functions of the respective units are realized by sequentially executing the programs developed on the memory, and processing, storing, and outputting data on the memory and data input via the interface. (The same applies throughout the specification.)

  “Portable terminal” (0200) refers to a mobile communication terminal equipped with a wireless communication function capable of transmitting and receiving calls and e-mails, as typified by a mobile phone and PHS.

  The “communication unit” (0201) has a function capable of making a call and sending / receiving mail, and can send and receive a call and send / receive mail simultaneously.

  The “notification mail holding unit” (0202) has a function of holding a notification mail to be transmitted to the call partner when a call at the communication unit (0201) cannot maintain a predetermined quality. “Predetermined quality cannot be maintained” means a state in which a call cannot be made normally. In addition to the state where the communication is cut off, the case where the call state is unstable and one or both of the voices of the call cannot be heard or the call is interrupted is included. When moving from the ground to the basement and cannot receive radio waves from the base station, when buildings such as buildings are blocked from radio waves, when entering into areas with few base stations such as mountainous areas, or moving at high speed This may occur due to an environment such as when the call state becomes unstable. Moreover, in the case of a portable terminal having a waterproof function, it also corresponds to a case where the mobile terminal has submerged to a depth at which wireless communication is difficult. In addition, you may include the thing which "predetermined quality cannot be maintained" for reasons unrelated to the wireless communication system, such as malfunctions of the mobile terminal itself, battery consumption, and flooding. The same applies to the following embodiments.

  “Notification email” refers to an email that informs the other party of the call that the call has been or may have been disconnected, and the reason. Further, the “notification mail” is transmitted from the mobile terminal to a predetermined address described later, and is transmitted from the predetermined address to a terminal where the call partner can be confirmed. An example of the notification mail is shown in FIG. A content that informs only that the user is out of service area as shown in (a) or a content that informs that a call is returned as shown in (b) may be added. Further, when the user knows in advance how long the out-of-call state will continue, for example, the content of “I will call you in one hour” may be added. For example, the time when the user gets on the subway for moving, or the time when the aircraft is boarded when a call disconnect time is set in advance for getting on an airplane. Moreover, you may notify the effect etc. of the portable terminal itself. In such a case, by acquiring failure cause information from a self-diagnostic function unit for self-diagnosis of the cause of the failure and embedding the information in a mail template, a notification mail having contents including the information can be generated. Furthermore, as shown in (c), the call partner may confirm the possibility of disconnecting the call before the call is disconnected. The “notification mail” is held in a storage device (0501) such as a nonvolatile semiconductor memory or a hard disk of the portable terminal shown in FIG.

  The “calling side quality determination unit” (0203) has a function of determining whether or not a call in the communication unit can maintain a predetermined call quality. Here, “determining whether or not it can be maintained” means predicting and determining whether or not it becomes impossible to maintain. That is, it means predicting and judging the call quality. The determination criterion may be, for example, that “a predetermined quality cannot be maintained” when a predetermined threshold value is set in the reception sensitivity (electric field strength) of the radio wave from the base station and falls below the threshold value. Further, it may be configured to determine that “predetermined quality cannot be maintained” when the vicinity of the threshold value is stagnated for a certain period of time and then falls below the threshold value. Moreover, you may comprise so that it may judge based on an error rate. In the case of a digital signal, since it is always observed how much error occurs in the received signal, when a predetermined threshold value is set and the threshold value is below or exceeds the threshold value, “the predetermined quality cannot be maintained. It is good also as. Moreover, it may be configured to predict movement of the mobile terminal and make a determination based on the prediction. The movement prediction may use the GPS function of the mobile terminal to predict that the mobile route will enter the area outside the calling area. In addition, when using the Felica communication function to get on and off a transportation facility, the destination may be predicted from the station used and predicted to enter an area outside the calling area. Here, the moving destination may be predicted using the past Felica communication history.

  Further, the communication quality may be determined based on the electric field strength relating to wireless means such as PHS, 2G, and 4G, femtocell, HotSpot, and one-segment broadcasting extremely small area broadcasting. In addition, when there is a difference between the electric field strength based on the fixed base station and the electric field strength related to extremely small area broadcasting, the determination may be made based on one or both of the electric field strengths.

  Furthermore, when the user himself / herself has made a reservation setting to turn off the power of the mobile terminal at a predetermined time, for example, 5 minutes before the reservation time, regardless of the actual call quality, It may be configured to determine that “predetermined quality cannot be maintained”.

  The “notification mail transmission control unit” (0204) displays the held notification mail when the determination result in the “calling side quality determination unit” (0203) is a determination result that the predetermined call quality cannot be maintained. It has the function to transmit to a predetermined address from a communication part. “Retained notification mail” refers to mail stored in the “notification mail storage unit” (0202). When a plurality of mails are held, a predetermined one mail is selected and transmitted. “Predetermined address” refers to an e-mail address, URL, IP address, Bluetooth pairing destination, Mac address, ID that can be identified within the system including this terminal, etc. A specific media address that sends a notification email to a terminal that can be confirmed.

Also, as shown in FIG. 4, the “portable terminal” (0400) may have an “editing unit” (0405). The “editing unit” (0405) has a function of editing the notification mail held in the “notification mail holding unit” (0402). This is effective in that the user can edit the contents of the notification mail. For example, as shown in FIG. 3, the content includes a call back, or the content indicating the time when the communicable time can be specified in advance.

  In the present embodiment, when searching for an available base station, it is determined whether it is within or outside the base station communication range, and if it is determined that it is out of range, the base station is searched by a power saving possible mode search. The present invention relates to a portable terminal.

  A functional block diagram is shown in FIG. 46, a hardware configuration diagram is shown in FIG. 47, and a processing flow is shown in FIG.

  An object of the present embodiment is to save power required for searching for available base stations when the mobile terminal is located outside the communication range. Searching for a base station means that the mobile terminal receives radio waves from the base station, transmits position information of the mobile terminal from the mobile terminal to the base station, and can communicate with the mobile terminal within a predetermined base station communication range. It is to be in a state. The term “outside base station communication area” includes areas other than the base station communication area, as well as areas where radio waves cannot be received, such as underground, tunnels, and locations where buildings are blocked.

  The out-of-service mode search of the present embodiment is, for example, to save power by reducing the number of searches within a certain time by making the base station search interval longer than the normal mode search. Further, the search interval for the base station may be changed depending on the elapsed time outside the service area, and it is more preferable that the user or the like can set the search interval.

Further, the base station may be searched only on the basis of a request from the outside such as a user of the mobile terminal or a server device, and if there is no request, the base station may not be searched. That is, when the determination result in the determination unit is out of the base station communication area, the base station is not searched as long as there is a request even if it moves into the base station communication area. For this reason, the mobile terminal is turned on and is located within the communication range of the base station, but is incapable of communication. This is effective when, for example, the base station communication area and the outside of the communication area move alternately. For example, it is effective when a game function, a music / video viewing function, etc. mounted on a mobile terminal in a train are used and it is not desired to be interrupted for receiving a mail or receiving a call on the way.
In addition, when moving from outside the base station communication range to the base station communication range and shifting from the out-of-service mode search to the normal mode search, mail that was created during the out-of-service mode search and could not be sent, e-mail with photos, etc. You may be comprised so that it may transmit automatically triggered by having shifted to mode search. Similarly, it may be configured to automatically check the received mail during the out-of-service mode search. Further, in the portable terminal having the notification mail transmission function of the embodiment, the notification mail that could not be transmitted before the call was disconnected is automatically transmitted with the transition to the normal mode search as a trigger. It may be configured.
The determination unit determines whether the mobile station is in the base station communication range or out of the base station communication range by using a GPS function, a thermometer, a water depth meter, or the like mounted on the mobile terminal. Moreover, it may be configured to make a determination using a schedule, a timer, or the like that is set and registered in advance in the mobile terminal by the user. The determination may be made using radio field strength such as PHS, 2G, and 4G, and electric field strength related to femtocell, HotSpot, one-segment broadcasting, and very small area broadcasting.

According to the present embodiment, it is possible to save the power of a mobile terminal that is out of communication range and cannot communicate, and the convenience is improved, for example, the terminal driving time with a limited battery capacity is increased.
