Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, parts corresponding to each other in all the drawings in this specification are denoted by the same reference numerals, and description of the overlapping parts will be omitted as appropriate.
(First embodiment)
FIG. 1 is a block diagram showing the configuration of a character display system for incoming calls according to the first embodiment of the present invention.

  1 includes a mobile communication network 11, a calling exchange (also referred to as a calling LMMS) 12 connected to the mobile communication network 11, and a subscriber DB (Data base). An SCP (Service Control Point) 13 having 13 a, an answering machine center (also referred to as NMIS) 14, an SC (Service Center) 15 that is a server for storing SMS, and a terminating exchange (also referred to as called LMMS) 16 And a plurality of mobile phones 21 and 22 that are wirelessly connected to the mobile communication network 11.

In addition, the originating exchange 12 includes a character information setting transmission device 12a, the answering machine center 14 includes an SMS conversion transmission device 14a, and the SC 15 includes an SMS storage / delivery device 15a.
However, in the present embodiment, one mobile phone 21 is also referred to as the originating MS 21 as the calling side, and the other mobile phone 22 is referred to as the called MS 22 as the receiving side.
The calling MS 21 performs processing for setting the character information as a call request signal when the user inputs character information by a key operation at the time of making a call, and then, when the user performs a call operation, the call request signal At the same time, the character information is transmitted to the originating exchange 12 via the mobile communication network 11 as indicated by the broken line arrow Y1.

In the present embodiment, the character information includes not only characters but also content information to which pictures and images are added. In addition to direct input of character information by key operation, various methods of specifying and inputting a file or the like can be considered.
When receiving the call request signal from the originating MS 21, the originating side exchange 12 makes an inquiry to the SCP 13 regarding the destination MS 22 as indicated by the broken line arrow Y 2. When a response to the answering machine activation instruction, which is an instruction as to whether or not to activate the answering machine, is returned from the SCP 13 in response to this service inquiry, the user is notified by voice or the like of whether or not to connect to the answering machine. The answering machine connection guidance signal is sent back to the originating MS 21.

In addition, after receiving the answering machine activation instruction from the SCP 13, the originating exchange 12 converts the answering machine center connection request instruction signal, which is a request instruction signal for connecting the originating MS 21 to the answering machine center 14 by the character information setting transmission device 12 a. After the character information is set, this answering machine center connection request instruction signal is transmitted to the answering machine center 14 as indicated by a broken line arrow Y3.
In response to the service inquiry of the originating side exchange 12, the SCP 13 also uses the inquiry to the terminating side exchange 16 to confirm whether the call is possible from the power-on / off state of the destination MS 22 or the location information. Referring to the subscriber DB 13a, confirmation of what service the destination MS 22 is subscribed to (additional service contract confirmation) and confirmation of whether the answering machine is activated (confirmation of the answering machine activation state) Do.

As a result of these confirmations, if the destination MS 22 is in a state where the telephone call cannot be made and the answering machine is active, the SCP 13 returns an answering machine activation instruction as a response to the originating side switch 12, as indicated by the broken line arrow Y2.
On the other hand, when it is confirmed in SCP 13 that the incoming MS 22 is in a call-ready state, the character information transmitted from the originating MS 21 is notified to the incoming MS 22 via the incoming side exchange 16 together with the incoming call and displayed on the display of the incoming MS 22 It has come to be.

When the answering machine center 14 receives the answering machine center connection request instruction signal from the originating side exchange 12, as shown by a broken line arrow Y3, as a general process, a connection response to the originating side exchange 12 and a billing start instruction A signal is sent back to the originating exchange 12 and a guidance for guiding the connection to the answering machine center 14 by voice or the like is transmitted to the originating MS 21.
Further, when the answering machine center 14 receives the previous answering machine center connection request instruction signal, the SMS conversion transmitter 14a converts the character information set in the received signal into an SMS signal, and then uses the broken line arrow Y4. As shown, a short message transfer request is made to the SC 15 and the SMS signal is transmitted. When the transfer request is properly accepted at SC15, the short message transfer response is returned from SC15 as indicated by the broken line arrow Y4. After receiving the response, the short message transfer request processing is terminated.

  The SC 15 stores the character information based on the SMS signal transferred from the answering machine center 14 in association with the incoming / outgoing telephone number and stores it in the SMS storage / delivery device 15a. After this storage, the short message transfer response is returned to the answering machine center 14. To do. Thereafter, when it is confirmed that the destination MS 22 is in a call-ready state by referring to the location information from the receiving side exchange 16, the accumulated character information is indicated by broken line arrows Y5 and Y6 by the SMS signal. As described above, it is delivered to the destination MS 22 via the receiving side exchange 16.

Next, referring to the sequence diagram shown in FIG. 2, the operation when the incoming MS 22 displays the character information transmitted at the time of outgoing call from the originating MS 21 at the time of incoming call in the character display system 10 at the time of incoming call of the telephone having such a configuration. explain.
First, in step S1, if the user inputs character information to be transmitted to the other party by a key operation at the time of outgoing call with MS 21, the input character information is set (superimposed) on the call request signal in step S2. Thereafter, when the user performs a call operation, a call request signal in which character information is set is transmitted to the call-side exchange 12 in step S3.

  When this call request signal is received by the caller-side exchange 12, in step S4, a service inquiry related to the destination MS 22 is made to the SCP 13. In response to this service inquiry, in step S5, the SCP 13 also uses the inquiry to the called exchange 16 to determine whether the incoming MS 22 is in a call-enabled state based on the power on / off state, location information, etc., and by referring to the subscriber DB 13a. Additional service contract confirmation as to what service the destination MS 22 subscribes to is performed. In parallel with this, in step S6, an answering machine active state check is performed as to whether or not the answering machine is activated.

Here, when it is confirmed that the destination MS 22 is in a call-ready state, the character information transmitted from the originating MS 21 is notified to the terminating MS 22 from the originating side switch 12 via the terminating side switch 16 together with the incoming MS 22 and received. Appears on the display.
On the other hand, if it is confirmed that the destination MS 22 is in a voice-disabled state and the answering machine active state, an answering machine activation instruction signal is returned as a response from the SCP 13 to the originating side switch 12 in step S7.

When this signal is received by the originating side exchange 12, in step S8, a message answering connection guidance signal is returned to the originating MS 21. As a result, the originating MS 21 notifies the user of guidance on whether or not to connect to the answering machine by voice.
Further, in the originating exchange 12, in step S9, after receiving the answering machine activation instruction from the SCP 13, character information is set in the answering machine center connection request instruction signal for connecting the originating MS 21 to the answering machine center 14. The The answering machine center connection request instruction signal after this setting is transmitted from the originating side exchange 12 to the answering machine center 14 in step S10.

The answering machine center 14 that has received this answering machine center connection request instruction signal sends a connection response to the originating exchange 12 in step S11, and the originating exchange 12 that has received this response sends it in step S12. Calling (not-delivered notification) is transmitted to the originating MS 21.
Further, the answering machine center 14 that has received the answering machine center connection request instruction signal returns a billing start instruction signal to the originating exchange 12 in step S13, and the originating exchange 12 that has received this instruction receives the instruction in step S14. Then, a connection for charging is made to the originating MS 21.

  Further, in the answering machine center 14, upon reception of the preceding answering machine center connection request instruction signal, in step S16, the character information set in the received signal is converted into an SMS signal. The SMS signal is transmitted in response to a short message transfer request to Further, in step S18, a guidance signal is transmitted to the originating MS 21 to give a voice guidance that the telephone answering center 14 has been connected.

In SC15 that has received the short message transfer request, in step S19, the character information based on the SMS signal transferred from the answering machine center 14 is stored in the SMS storage / delivery device 15a in association with the outgoing / incoming telephone number. The After the accumulation, a short message transfer response is returned to the answering machine center 14 in step S20.
Thereafter, it is assumed in SC 15 that it is confirmed that the called MS 22 is in a call-ready state by referring to the location information from the called exchange 16. In this case, in step S21, the accumulated character information is delivered to the destination MS 22 via the terminating exchange 16 in steps S22 and S23 by an SMS signal. As a result, the character information from the calling MS 21 is displayed on the called MS 22 together with the calling telephone number.

  As described above, according to the incoming call character display system 10 of the first embodiment, when the calling side exchange 12 receives a call request signal in which character information input at the time of calling the originating MS 21 is received, When the answering machine activation state of the destination MS 22 is notified from the SCP 13 which is a service control point for subscriber information management, the originating MS 21 is sent to the answering machine center 14 by the character information setting transmission device (character information setting transmission means) 12a. Character information is set in the answering machine center connection request instruction signal (connection request signal) for connection, and the connection request signal after this setting is transmitted to the answering machine center 14.

When the answering machine center 14 receives the connection request signal in which the previous character information is set, the SMS conversion transmitter 14a converts the character information in the received signal into an SMS signal which is a short message. The data is transmitted to the storage server SC15.
In SC15, the character information converted into the SMS signal is received and stored in the SMS storage / delivery device 15a in association with the calling telephone number, and the stored character information and the calling telephone number are stored in the call-enabled MS 22 state. When it becomes, it is delivered to the destination MS 22 by the SMS signal.

As a result, even if the destination MS 22 is out of communication range, for example, if it is in a call-disabled state, it is possible to make a call with one call operation by inputting character information and making a call when making a call from the calling MS 21. When the telephone is ready to return to the service area, the previously transmitted character information can be displayed together with the calling telephone number. Therefore, even an important message can be reliably transmitted to the other party by text information, and since it is a short message, there is an advantage that the other party can receive and display it for free.
(Second Embodiment)
FIG. 3 is a sequence diagram for explaining the operation of the incoming call character display system according to the second embodiment of the present invention.

The character display system at the time of incoming call of the second embodiment is different from the first embodiment in that the call of the called MS 22 is made without accessing the answering machine center 14 explained in the first embodiment. It is that the character information can be distributed after checking the state.
In order to realize this, as shown in FIG. 3, the originating exchange 12 is provided with an incoming call state confirmation device 12b, an SMS conversion / transmission device 12c, and a character information setting transmission device 12a as in the first embodiment. In addition, the SMS storage / delivery device 15a is provided in the SC15.

When receiving the call request signal from the originating MS 21, the called party call state confirmation device 12b makes an incoming call state inquiry for confirming whether the destination MS 22 indicated by the call request signal is in a call-enabled state. Then, it is confirmed from the response content of the SCP 13 according to this whether the destination MS 22 is in a call enabled state or a call disabled state.
The SMS conversion transmission device 12c converts the character information set in the call request signal into an SMS signal when the incoming call state confirmation device 12b confirms that the destination MS 22 is in a call impossible state, and then sends a short message to the SC15. A transfer request is made and the SMS signal is transmitted. When the transfer request is properly accepted by the SC 15, a short message transfer response is returned from the SC 15, and the short message transfer request processing is terminated after receiving the response.

Next, with reference to the sequence diagram shown in FIG. 3, an explanation will be given of the operation when the destination MS 22 displays the character information transmitted from the calling MS 21 at the time of calling in the incoming call character display system having such a configuration. To do.
First, in step S31, when the user inputs character information to be transmitted to the other party by a key operation at the time of outgoing call with the originating MS 21, in step S32, the input character information is set (superimposed) on the outgoing call request signal. Thereafter, when the user performs a call operation, a call request signal in which character information is set is transmitted to the call-side exchange 12 in step S33.

When this outgoing call request signal is received by the outgoing side exchange 12, in step S34, the incoming call side call state confirmation device 12b checks whether the called destination MS 22 indicated by the outgoing call request signal is in a call ready state. An incoming call state inquiry is made to the SCP 13.
As a result, in step S35, it is confirmed in SCP 13 whether or not a call is possible from the power on / off state of the destination MS 22 and the location information by using an inquiry to the receiving side exchange 16 together.

Here, when it is confirmed that the destination MS 22 is in a call-ready state, the character information transmitted from the originating MS 21 is notified to the terminating MS 22 from the originating side switch 12 via the terminating side switch 16 together with the incoming MS 22 and received. Appears on the display.
On the other hand, if it is confirmed that the destination MS 22 is in a call-disabled state and an answering machine active state, a response indicating that the call cannot be received is returned from the SCP 13 to the originating exchange 12 in step S36. In the receiving side call state confirmation device 12b of the originating side exchange 12, it is confirmed from the response that the destination MS 22 is in a call impossible state.

By this confirmation, in the SMS conversion transmitting device 12c, in step S37, the character information set in the transmission request signal that has already been received is converted into an SMS signal, and thereafter, the SMS signal is transmitted by a short message transfer request to the SC15. Is sent.
In SC15 which has received this short message transfer request, in step S38, the character information based on the SMS signal transferred from the answering machine center 14 is stored in the SMS storage / delivery device 15a in association with the outgoing / incoming telephone number. . After this accumulation, a short message transfer response is returned to the originating side exchange 12 in step S39.

  Thereafter, when it is confirmed in SC15 that the called MS 22 is in a call-ready state by referring to the location information from the receiving side exchange 16, the stored character information is converted to the SMS signal in step S40. In S41 and S42, the message is delivered to the destination MS 22 via the receiving side exchange 16. As a result, the character information from the calling MS 21 is displayed on the called MS 22 together with the calling telephone number.

  Thus, according to the incoming call character display system of the second embodiment, when the originating side switch 12 receives the origination request signal from the originating MS 21, the terminating side call state confirmation device 12b causes the SCP 13 to By making an inquiry, it is confirmed whether or not the destination MS 22 indicated by the call request signal is ready for a call. When it is confirmed that the call cannot be made, the SMS conversion / transmission device 12c converts the character information in the previous call request signal into an SMS signal and then transmits it to the SC15. The SC 15 receives the character information converted into the SMS signal by the SMS storage device 15a, stores the character information in association with the calling telephone number, and stores the stored calling telephone number and character information in a state in which the destination MS 22 can make a call. When it becomes, it is delivered to the destination MS 22 by the SMS signal.

  As a result, even if the destination MS 22 is out of communication range, for example, if it is in a call-disabled state, it is possible to make a call with one call operation by inputting character information and making a call when making a call from the calling MS 21. When the telephone is ready to return to the service area, the previously transmitted character information can be displayed together with the calling telephone number. Therefore, even an important message can be reliably transmitted to the other party by text information, and since it is a short message, there is an advantage that the other party can receive and display it for free. Further, in the second embodiment, unlike the first embodiment, since the answering machine center 14 is not routed, the entire system can be simplified correspondingly.
