Description

  The present invention relates to a communication terminal that accepts a call establishment request from a calling terminal and an incoming call control method.

Conventionally, when there is an incoming call from a specific partner, there is a communication terminal that displays that fact in a format different from normal. For example, Patent Literature 1 below describes a mobile phone that displays partner data in a special color when an incoming call is received from a specific communication terminal. This mobile phone stores data indicating a specific destination in advance, and determines whether the destination data is a specific destination when receiving a call. If it is a specific partner, the mobile phone displays the partner data in a color different from that of the normal partner. That is, the mobile phone disclosed in Patent Document 1 below is based on the assumption that the caller can be specifically identified as to whether or not the caller is a special partner (for example, a lover or family member) for the callee. Judging.
JP 2001-111675 A

  However, even when the caller cannot be specified specifically, there are situations where the caller is a special partner for the callee. Specifically, this is a case where the caller returns the call to the callee. As an example, a user who makes a reservation call to a restaurant for the first time receives a confirmation call from the restaurant. In this case, even if the user does not register the phone book data of the restaurant in his / her terminal, the restaurant (sender) is the user whom the user tried to contact once before. Should be able to answer the phone with peace of mind. However, unless the phone book data of the caller is registered in the communication terminal, it is very difficult to identify the caller, and the callee hesitates to respond. As a result, communication opportunities are lost.

  The present invention has been made to solve the above-described problem, and is a communication terminal capable of notifying a callee that a call is returned from the caller even when the caller cannot be specifically identified. And an incoming call control method.

  The communication terminal of the present invention includes a call history storage means for storing a telephone number of the other communication terminal when the call is sent to the other communication terminal, a receiving means for receiving a call establishment request signal transmitted from the calling terminal, and a receiving means. The extraction means for extracting the telephone number of the calling terminal from the call establishment request signal received by the mobile terminal, and when the telephone number extracted by the extracting means is stored in the outgoing call history storage means, the call establishment request signal is sent from the calling terminal Determining means for determining that the call is a signal indicating a return telephone, and when the determination means determines that the call establishment request signal is a signal indicating a return telephone, the telephone number of the calling terminal and the return telephone Output means for associating and outputting information indicating this.

  Also, the incoming call control method of the present invention is an incoming call control method in a communication terminal provided with outgoing history storage means for storing a telephone number of the counterpart communication terminal when the call is sent to the counterpart communication terminal. A reception step for receiving a call establishment request signal, an extraction step for extracting the telephone number of the calling terminal from the call establishment request signal received in the reception step, and the telephone number extracted in the extraction step are stored in the transmission history storage means. Determining that the call establishment request signal is a signal indicating a return telephone call from the calling terminal, and determining that the call establishment request signal is a signal indicating a return telephone call in the determination step. And an output step of associating and outputting the telephone number of the calling terminal and information indicating that it is a return telephone. .

  According to such a communication terminal and the incoming call control method, the telephone number of the calling terminal extracted from the received call establishment request signal (hereinafter also referred to as “the called number”) is compared with the outgoing call history, and the incoming call number is sent. If stored as a history, it is determined that the call has been returned from the caller. Then, information indicating that the call is returned is output together with the incoming call number. Thus, by collating the incoming call number with the outgoing call history, even if the caller cannot be specifically identified, it is possible to notify the callee that the call is a return call from the caller.

  The communication terminal of the present invention further includes a telephone directory storage means for storing telephone directory data including the telephone number of the partner communication terminal, and the determination means stores the telephone directory data including the telephone number extracted by the extraction means as a telephone directory storage. When the telephone number is not stored in the means and the telephone number is stored in the outgoing call history storage means, it is preferable to determine that the call establishment request signal is a signal indicating a return telephone call from the calling terminal.

  In this case, when the extracted telephone number (incoming number) is not stored as telephone directory data and remains in the outgoing call history, it is determined that the telephone call has been returned from the caller. This makes it possible to notify the recipient that the incoming call is from a partner who has not been registered in the phone book but has previously called.

  According to such a communication terminal and the incoming call control method, the incoming call number extracted from the call establishment request signal and the outgoing call history are compared to determine whether or not the call is a return call. Even if the call cannot be made, the callee can be notified that the call is a return call from the caller.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, the communication terminal according to the present invention is applied to a mobile phone. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  The mobile phone 10 is a communication terminal capable of establishing a call with another communication terminal such as a mobile phone or a fixed phone. In the present embodiment, a mobile phone M is illustrated as another communication terminal. The cellular phone 10 includes, as functional components, a transmission history storage unit (transmission history storage unit) 11, a telephone directory storage unit (phone book storage unit) 12, a reception unit (reception unit) 13, an extraction unit (extraction unit) 14, A determination unit (determination unit) 15 and an output unit (output unit) 16 are provided.

  As shown in FIG. 2, the mobile phone 10 includes a CPU 101 that executes an operating system, application programs, and the like, a main storage unit 102 that includes a ROM and a RAM, an auxiliary storage unit 103 that includes a memory, and the like. A communication control unit 104 that performs data communication via a mobile communication network that is not connected, an operation unit 105 that includes keys for character input, and an output unit 106 that includes a liquid crystal monitor and a speaker. Each function of the mobile phone 10 reads predetermined software on the CPU 101 and the main storage unit 102, operates the communication control unit 104 under the control of the CPU 101, and controls the main storage unit 102 and the auxiliary storage unit 103. This is achieved by reading and writing data.

  The outgoing call history storage unit 11 is a part that stores the telephone number (calling number) of the partner communication terminal when the call is sent to the partner communication terminal. In the present embodiment, the partner communication terminal is the mobile phone M or another communication terminal (not shown) (such as a mobile phone or a fixed phone). When the mobile phone 10 performs a calling process on the partner communication terminal, the calling number is stored in the calling history storage unit 11. At this time, other information such as the name and transmission time of the user of the other communication terminal may be associated with the transmission number and stored in the transmission history storage unit 11. The outgoing call history storage unit 11 stores a predetermined number of telephone numbers that have been subjected to outgoing call processing as a outgoing call history (redial).

  The telephone directory storage unit 12 is a part that stores telephone directory data including the telephone number of the partner communication terminal. The phone book storage unit 12 can store a predetermined maximum number of phone book data input and registered by the user of the mobile phone 10. The phone book data includes information of the partner communication terminal such as a telephone number, name, and mail address, and personal information of the user.

  The receiving unit 13 is a part that receives a call establishment request signal (incoming signal) transmitted from a transmitting terminal (for example, the mobile phone M). For example, when a user of the mobile phone M dials the telephone number of the mobile phone 10 and issues a call instruction, a call establishment request signal is transmitted from the mobile phone M and transmitted to the mobile phone 10 via a mobile communication network (not shown). The The receiving unit 13 receives the call establishment request signal via the antenna 13 a and outputs it to the extracting unit 14.

  The extraction unit 14 is a part that extracts the telephone number (incoming number) of the calling terminal from the call establishment request signal received by the reception unit 13. The extraction unit 14 decodes the input call establishment request signal and acquires the incoming call number. Then, the extraction unit 14 outputs the extracted incoming call number to the determination unit 15.

  When the phonebook data including the incoming call number extracted by the extraction unit 14 is not stored in the phonebook storage unit 12 and the incoming call number is stored in the outgoing call history storage unit 11, the determination unit 15 This is a part that determines that the call establishment request signal received by the receiving unit 13 is a signal indicating a return telephone call from the calling terminal.

  When the incoming number is input, the determination unit 15 checks whether or not the phone book data including the incoming number is stored in the phone book storage unit 12. At this time, if such telephone directory data cannot be extracted, the determination unit 15 checks whether the incoming call number is stored in the outgoing call history storage unit 11. If the incoming call number can be extracted from the outgoing call history storage unit 11, the determination unit 15 determines that the call establishment request signal from the calling terminal is a signal indicating a return call, and has received a return call. Is generated, and the incoming call number and the callback signal are output to the output unit 16.

  On the other hand, when the inputted incoming call number can be extracted from the telephone directory storage unit 12, or when the incoming call number cannot be extracted from the telephone directory storage unit 12 or the outgoing call history storage unit 11, the determination unit 15 Then, it is determined that the call establishment request signal from the calling terminal is not a signal indicating a return telephone. In this case, the determination unit 15 generates a normal call signal indicating that the call is not a return call, and outputs the incoming call number and the normal call signal to the output unit 16.

  The determination unit 15 uses the verification rule shown in FIG. 3 when verifying the incoming number and the telephone number in the outgoing call history storage unit 11. The determination unit 15 stores a verification rule in advance, and reads the verification rule during the determination process. In FIG. 3, the telephone number to be collated is a telephone number stored in the outgoing call history storage unit 11. The number “0xxxxxxxxxx” indicates a normal telephone number without a country code. The number “+ 81xxxxxxxxxx” is a telephone number to which a country code “81” is added, and the number “+ oooxxxxxxxxxx” is a telephone number to which a country code “oo” other than “81” is added. The character string “* xxxx” is a sub address. The character string “* 59n # (n = 0 to 3)” is a number assigned to select a number to be used in a communication terminal that can use a plurality of telephone numbers.

  For example, when the incoming number is “+ 81xxxxxxxxxx”, the determination unit 15 does not have the incoming number in the outgoing history storage unit 11 just by storing the number “+ 81xxxxxxxxxx * xxxx” in the outgoing history storage unit 11. Is determined. On the other hand, when the incoming number is “0xxxxxxxxxx” and the outgoing call history storage unit 11 does not have the number “0xxxxxxxxxx” but the number “0xxxxxxxxxx * 591 #” exists, the determination unit 15 receives the incoming number. It is determined that it is stored in the outgoing call history storage unit 11. In addition, the collation rule shown in FIG. 3 is only an example. For example, only a part of the collation rule shown in FIG. 3 may be used, or the collation determination value (“match” or “mismatch”) may be changed.

  The output unit 16 is a part that associates and outputs an incoming number and information indicating a return phone call when the determination unit 15 determines that the call establishment request signal is a signal indicating a return phone call. .

  When a callback signal is input, the output unit 16 associates the incoming call number input simultaneously with the character string “return incoming call” and displays these information on the incoming call screen. The character string “callback” corresponds to information indicating that the call is a call back. Further, the output unit 16 associates the incoming call number with the character string “return incoming call” and stores it in the incoming call history storage unit (not shown) as an incoming call history. On the other hand, when a normal call signal is input, the output unit 16 displays only the incoming call number on the incoming call screen and stores the incoming call number in the incoming call history storage unit.

  The incoming call screen when the callback signal is input is as shown in FIG. In FIG. 4, the character string “return incoming” is displayed immediately above the incoming call number “0xxxxxxxxxx”. On the other hand, the incoming call history when a callback signal is input is as shown in FIG. In FIG. 5, five incoming call histories are displayed, and the uppermost incoming call information among them shows that there is a return call from a user who is not registered in the phone book. The other four cases are incoming calls from users registered in the telephone directory, and therefore the character string “return incoming call” is not displayed even if it is a return call.

  Next, the processing of the mobile phone 10 shown in FIG. 1 will be described using FIG. 6 and the incoming call control method according to the present embodiment will be described. FIG. 6 is a flowchart showing processing of the mobile phone 10. Here, a process when the call establishment request signal is transmitted from the mobile phone M to the mobile phone 10 as a result of the mobile phone M executing the call processing for the mobile phone 10 will be described.

  In the mobile phone 10, the receiving unit 13 first receives the call establishment request signal (step S11, receiving step). Subsequently, the extraction unit 14 decodes the call establishment request signal and extracts the telephone number (incoming number) of the mobile phone M (step S12, extraction step).

  Subsequently, the determination unit 15 determines whether or not the call establishment request signal is a signal indicating a return telephone. Specifically, the determination unit 15 determines whether or not the phone book data including the incoming call number is stored in the phone book storage unit 12 (step S13, determination step). At this time, if such telephone directory data does not exist in the telephone directory storage unit 12 (step S13; NO), the determination unit 15 further determines whether or not the incoming call number is stored in the outgoing call history storage unit 11. Determination (step S14, determination step). If the incoming call number is stored as a call history (step S14; YES), the determination unit 15 determines that the received call establishment request signal is a signal indicating a return telephone (step S15, determination step). . Thereafter, the output unit 16 associates the incoming number with the character string “callback” indicating that the call is a return call, and displays an incoming call screen as shown in FIG. 4, for example (step S16, output step).

  On the other hand, when the telephone directory data including the incoming call number is stored in the telephone directory storage unit 12 (step S13; YES), or when the incoming call number is not stored in the outgoing call history storage unit 11 (step S14; NO). The determination unit 15 determines that the received call establishment request signal is not a signal indicating a return telephone (step S17). In this case, the output unit 16 displays only the incoming call number on the incoming call screen and stores the incoming call number in an incoming call history storage unit (not shown) (step S18).

  The determination unit 15 may first collate the incoming call number with the outgoing call history, and collate the incoming call number with the phone book data based on the result. That is, the order of the processes in steps S13 and S14 may be reversed.

  As described above, according to the present embodiment, even if the caller cannot be specifically identified by collating the incoming call number with the call history, the call back from the caller (for example, the user of the mobile phone M) can be returned. It is possible to notify the called party (user of the mobile phone 10) that it is a telephone call. As a result, the recipient can determine that the incoming call has been contacted (or attempted to make a contact) and can answer the call with peace of mind. As a result, loss of communication opportunities can be prevented. In addition, the telecommunications carrier can avoid loss of revenue opportunities such as call charges.

  In particular, in the present embodiment, when the incoming call number is not stored as phonebook data and remains in the outgoing call history, it is determined that the call has been returned from the caller. As a result, it is possible to notify the recipient (user of the mobile phone 10) that the incoming call is from the other party who made the call, but is not registered in the phone book.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the above embodiment, when the determination unit 15 does not store the phone book data including the incoming call number in the phone book storage unit 12 and the incoming call number is stored in the outgoing call history storage unit 11, the call is returned. However, the determination method is not limited to this. For example, the determination unit may inspect only the outgoing call history storage unit and determine that the call has been returned if the incoming call number is stored as the outgoing call history. That is, the process of step 13 in FIG. 6 is omitted. In this case, since it is not necessary to inspect the telephone directory storage unit, the processing is simplified.

  In addition, the determination unit may execute the collation with the incoming call number only in the outgoing call history stored in the outgoing call history storage unit for the outgoing call number transmitted within a predetermined time. For example, the determination unit may collate a transmission number transmitted within 24 hours from the current time with an incoming call number. Further, the time range for determining the collation range may be set by the input of the user of the communication terminal. Based on the time range input by the user and stored in a predetermined memory, the incoming call number and the outgoing call history are collated, so that the call is returned in accordance with the user's judgment criteria regarding whether or not the call is a return call. You can notify the recipient that you are on the phone.

  In the above embodiment, the communication terminal according to the present invention is applied to the mobile phone 10, but the present invention can be applied to various communication terminals such as other types of mobile communication terminals and fixed telephones.
