Description

  The present invention relates to a mobile phone terminal, and more particularly to a mobile phone terminal that can be suitably used when communication such as an emergency call is desired from outside a wireless public network area (out of service area).

  In recent years, with the spread of mobile phones, the area that can communicate via the wireless public network is expanding, but because it is preferentially expanded for areas with a large population, there are few populations such as mountains and coasts Many areas remain as out-of-service areas where communication is still impossible. Especially in the mountainous area, many climbers and skiers visit and may encounter accidents such as distress.

  If an emergency call via a mobile phone is required in such an area, communication via a mobile phone is not possible because it is out of service area, there is no way to notify the occurrence of an accident, etc. Is likely to be larger. In order to prevent the occurrence of such a situation, various methods for enabling communication outside the service area have been proposed.

  For example, a SIM (subscriber) having a mode in which a mobile station directly communicates with a base station and a mode in which communication of other mobile stations is relayed and having user information (ID) necessary for authentication to connect to a fixed network A communication system capable of mounting an identification module) card has been proposed by the following Patent Document 1 and the like. Further, Patent Literature 2 proposes a call setting method in which a mobile relay station logs on a mobile station communication to a network based on the SIM ID assigned to the mobile station.

  In addition, in a room where the radio public network signal is difficult to reach for mobile phones, a self-supporting base that enables emergency calls and location searches by having a parent-child relationship with the base station (main unit). A station has been proposed by Patent Document 3 and the like. Further, Patent Document 4 proposes a communication device having a power supply connection means that relays wireless communication between a mobile phone and a base station and enables outgoing and incoming calls from mobile phones outside the service area.

  Further, when a normal communication means cannot be used, a portable terminal that switches to communication with a satellite and enables communication with a notification destination set in advance via the satellite is proposed by Patent Document 5 and the like Has been. Further, Patent Document 6 proposes a micro wireless base station that performs communication from a micro base station to a mobile phone network via a wired public network (fixed telephone network).

  Further, a communication method for expanding the range of use of a mobile phone by providing the mobile phone with a function as a relay station is disclosed in Patent Literature 7, Patent Literature 8, Patent Literature 9, Patent Literature 10, Patent Literature 11, Patent It is proposed by Document 12 and the like.

  In addition, when the emergency call communication means cannot communicate with the radio base station, the relay request signal is issued to request the relay of the emergency call and the relay request signal is transmitted. Patent Document 13 proposes an emergency call device that stores emergency call information and transmits information when communication with a radio base station becomes possible.

  In recent years, mobile phones have become widespread, and few people have mobile phone terminals for the first time, and demand for replacement from old models to new models is increasing. For this reason, mobile phone terminals that have been used before can no longer be used by replacement and are often discarded as garbage.

The mobile phone terminal in the transmission mode transmits a sound signal such as a different scale or pitch set to each key from the individual communication unit 200 as a communicable signal similar to an audio signal when a key is input.

  The voice recognition unit 5-1 of the individual communication unit 200 of the mobile phone terminal in the relay mode restores the number information of the key of several digits from the sound signal, and the number information is a several digit identification number set in advance by the user. A comparison determination is made as to whether or not (ID) matches. It is also possible to add modifications such as setting a combination of multiple sounds for each key.

  FIG. 6 shows an operation flow of a mobile phone terminal that performs identification number (ID) analysis. The user sets the relay mode for one mobile phone terminal in which the USIM card is mounted (6-1). The mobile phone terminal (relay machine) set to the relay mode confirms that the USIM card is installed and that it is within the wireless public network (6-2, 6-3).

  Next, the user sets an identification number (ID) of several digits using the key (6-4). The mobile phone terminal (relay machine) set to the relay mode stores the identification number (ID). In addition, the user sets a telephone number of a communication partner such as an emergency contact address. The cellular phone terminal (relay machine) set to the relay mode stores this telephone number, and makes a call to this telephone number via the wireless public network at the time of emergency contact or the like. When the above setting is completed, the mobile phone terminal shifts to the relay mode (6-7).

  The user sets the outgoing mode for mobile phone terminals other than the mobile phone terminal that has set the relay mode (6-8). The mobile phone terminal in which the transmission mode is set shifts to the transmission mode (6-9), and communication using the individual communication unit becomes possible.

  After completing the above two mode settings, the user moves out of service area with the mobile phone terminal (transmitter) in the outgoing mode with the mobile phone terminal (relay machine) in the relay mode in the area of the wireless public network. (6-10). When a user needs to make a communication such as an emergency call, the user makes a call such as an emergency call using a mobile phone terminal (transmitter) in a call mode (6-11), and inputs an identification number (ID) key. (6-12).

  The mobile phone terminal (transmitter) in the transmission mode transmits the identification number (ID) from the individual communication antenna (6-13). The mobile phone terminal (relay machine) in the relay mode analyzes the identification number (ID) by the ID analysis unit of the individual communication unit for the signal received by the individual communication antenna (6-14).

  The mobile phone terminal (relay device) in the relay mode performs a comparison determination whether the identification number (ID) received by the individual communication antenna matches the identification number (ID) set in advance by the user when setting the relay mode ( 6-15). If the two match, the mobile phone terminal (relay machine) in the relay mode calls the telephone number set when the relay mode is set (6-16).

  In addition, the cellular phone terminal (relay machine) in the relay mode controls the voice control unit to output the voice signal input from the receiving unit of the individual communication unit to the wireless public network communication unit, and performs wireless public network communication. The audio signal input from the control unit is controlled to be output to the transmission unit of the individual communication unit.

  In addition, the mobile phone terminal (transmitter) in the transmission mode controls the audio control unit to output the audio signal input from the microphone to the transmission unit of the individual communication unit, and is input from the reception unit of the individual communication unit. The audio signal is controlled to be output to the speaker. As a result, the user can talk (6-17).

  In addition, when a mismatch between the received identification number (ID) and a preset identification number (ID) is detected in the mobile phone terminal (relay machine) in the relay mode, the fact that the identification number (ID) does not match is individually The user is notified via the communication unit (6-18). When the user receives a notification that the identification number (ID) does not match, the user can return to the operation flow (6-11) for sending an emergency call and perform the operation again.

  Here, the USIM card 1-8 shown in FIG. 1 will be described. The USIM is an abbreviation for Universal Subscriber Identity Module (general subscriber identification module), and the user's telephone number, contracted mobile phone operator information, and the like are recorded in the USIM card. By attaching the USIM card 1-8 to the mobile phone terminal, the terminal can be used with the telephone number recorded in the USIM card.

  When the mobile phone terminal is located in the wireless public network area (within the area) with the USIM card 1-8 attached, the mobile phone terminal controls the incoming call by the user's key operation or the incoming call from the base station. The wireless public network communication unit 100 is operated by the control of the unit 1-12 to realize normal mobile communication. However, even if the mobile phone terminal is located in the wireless public network area (within the area), the control unit 1-12 controls the wireless public network communication unit 100 not to operate when the USIM card 1-8 is not installed. Communication is limited.

  FIG. 7 shows an effective function unit of a mobile phone terminal without a USIM card. As shown in the figure, the effective function unit of the mobile phone terminal in which the USIM card is not attached is an audio control unit 1-5, a speaker 1-6, a microphone 1-7 other than the wireless public network communication unit 100, Display unit 1-10, key input unit 1-11, control unit 1-12, peripheral unit 1-13, memory unit 1-14, individual communication antenna 1-15, transmission unit 1-16, and reception unit 1-17 It is.
