DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. 1 to 6 show an embodiment of the present invention.
[0019]
First, a first embodiment according to the present invention will be described with reference to FIG. As shown in FIG. 1, the present embodiment includes an antenna 110 that transmits / receives data to / from the network, a modulation unit 120 that modulates data received by the antenna 110 or data generated on the mobile phone side, and an answering machine Control unit 130 including / none determination unit 131, timer count unit 140 that counts the time until confirmation of whether there is an answering machine message, an operation unit 150 that the user performs an actual operation, and an answering machine And a display unit 160 for displaying that there is a recorded message. An answering machine presence / absence determination unit 131 provided in the control unit 130 determines whether an answering machine message is registered based on a signal transmitted from the network side.
[0020]
A signal transmitted from the radio base station is received by the antenna 110, A / D converted via the modulation unit 120, and taken into the control unit 130. The control unit 130 displays an incoming call on the display unit 160 and notifies the user of an incoming call by sounding a ring tone through a speaker (not shown). Here, when the user performs a call operation using the operation unit 150, the call state is entered.
[0021]
When the operation input by the user is not input and the incoming call is interrupted, the timer count unit 140 counts a predetermined time M. The predetermined time M is a time that takes into account the time during which an answering machine message will be recorded. After the elapse of M hours, the timer count unit 140 notifies the control unit 130 that the M time has been counted. The control unit 130 transmits a “call setting” signal from the antenna 110 to the network side via the modulation unit 120. The network side that has received the “call setting” signal transmits a “call setting acceptance” signal to the mobile phone side. The “call setting acceptance” signal includes data indicating whether or not an answering machine message addressed to the mobile phone is registered in the answering machine service center.
[0022]
An answering machine presence / absence determination unit 131 in the control unit 130 determines whether or not an answering machine message is registered in the answering machine service center based on a “call setting acceptance” signal transmitted from the network side. When there is an answering machine message, the control unit 130 causes the display unit 160 to display a display indicating that there is an answering machine message. If there is no answering machine message, control unit 130 does not perform any operation on display unit 160. Thereafter, the control unit 130 transmits a “call disconnection” signal from the antenna 110, and the communication end operation is performed.
[0023]
Here, in general, “call setting” is bidirectional, and is a signal transmitted from the mobile phone to the network in the case of an outgoing call and received from the network to the mobile phone in the case of an incoming call. The data indicating whether the answering machine message is registered exists only in the “call setting” and “call setting acceptance” signals transmitted from the network to the mobile phone.
[0024]
Next, the operation procedure of this embodiment will be described with reference to the flowchart shown in FIG.
First, an incoming call to the user's mobile phone is received by the antenna 110 (step S1). When the user can answer the call from the mobile phone (step S2 / YES), the user enters a call state by operating the operation unit 150 (step S3).
[0025]
If the call cannot be answered in step S2 (step S2 / NO), the incoming call is disconnected (step S4), and the mobile phone is in a state with a missed call (step S5). At this time, the timer count unit 140 starts timer counting (step S6).
[0026]
When the timer count unit 140 counts a preset setting value M (step S6 / YES), the mobile phone transmits a “call setting” signal to check whether an answering machine message exists in the answering machine service center. Is transmitted (step S7). As a response to the “call setting” signal, a “call setting acceptance” signal is transmitted from the network to the mobile phone. This “call setting acceptance” signal includes a bit indicating whether or not an answering machine message is registered in the answering machine service center.
[0027]
The answering machine presence / absence determination unit 131 of the mobile phone determines whether or not an answering machine message is registered based on the received “call setting acceptance” signal (step S9). When it is determined that there is an answering machine message (step S9 / YES), the display unit 160 displays that an answering machine message exists (step S10), and the call is disconnected. If it is determined that there is no answering machine message (step S9 / NO), the call is disconnected and the series of operations is terminated.
[0028]
Next, an example of a communication sequence between the PDC mobile phone and the network (wireless base station) will be described with reference to FIG.
At 301, the network transmits paging to the mobile phone that should receive the call. The mobile phone that has received the paging transmits an incoming radio status report at 302 and performs an authentication operation at 303 and 304. After the authentication is completed, the network designates a radio channel at 305 and transmits the call setting at 306. At this time, the mobile phone is in an incoming state and is in a state of performing a calling operation. If the user cannot answer the incoming call, the operation for disconnecting the communication is started. The cellular phone transmits disconnection at 307, receives release from the network at 308, and transmits release completion at 309. When the network transmits a release completion, the network transmits a radio channel disconnection at 310, and the mobile phone transmits a radio channel disconnection completion at 311 and ends the incoming call operation. The above operation is a sequence generally defined in the PDC communication system.
[0029]
Here, in 311, since there is a missed call state by wireless channel disconnection completion transmission, the mobile phone starts timer counting. At the moment when the timer count value reaches the timer set value M, the operation moves to an operation for checking whether or not an answering machine message is left in the answering service center. At 312, the mobile phone transmits a call setup signal to receive a call setup reception including data with / without answering machine at 313 after transmitting the outgoing radio status report. The mobile phone that has received the call setting signal at 314 does not need to perform any further communication, and therefore performs a communication end operation. In 315, a disconnection is transmitted, and the network that has received the disconnection transmits a release in 316. In 317, the portable radiotelephone transmits a release completion, and the series of operations ends.
[0030]
As described above, in the present embodiment, when the missed call state is entered, the timer count unit 140 starts the timer count, and at the moment when the timer setting value is reached, the mobile phone confirms whether there is an answering machine message. Communication. For this reason, when it is not possible to answer the incoming call, it can be confirmed without a time lag that the caller has left the answering machine message.
[0031]
In addition, by using the existing “call setting” signal and “call setting acceptance” signal to check whether there is an answering machine message in the answering machine service center, the system on the network side (exchange or radio base station) side There is no need to change.
[0032]
Next, a second embodiment according to the present invention will be described with reference to the accompanying drawings. In this embodiment, the presence / absence of an answering machine message is confirmed when the mobile phone returns from outside the service area to within the service area. The operation procedure of the present embodiment will be described with reference to FIG.
When returning from outside the service area due to location movement or the like (step S11 / YES), position registration is performed and a standby state is entered (step S12). The mobile phone in the standby state transmits a “call setting” signal to confirm whether the answering machine message is stored when the mobile phone is out of service area (step S13). Thereafter, a “call setting acceptance” signal including the presence / absence bit of the answering machine message is received from the network (step S14).
[0033]
In the mobile phone that has received the “call setting acceptance” signal, the answering machine presence / absence determination unit 131 in the control unit 130 determines the presence / absence of an answering machine message (step S15). When it is determined that there is an answering machine message (step S15 / YES), the display unit 160 displays that an answering machine message exists (step S16), disconnects the communication, and ends the series of operations. If it is determined that there is no answering machine message (NO in step S15), the communication is disconnected and the series of operations is terminated.
[0034]
Next, a communication sequence when the mobile phone returns from outside the service area to the service area will be described with reference to FIG.
The mobile phone transmits a location registration request signal 501 to the network 2 for location registration. The network 2 that has received the location registration request signal transmits an authentication request signal 502 to the mobile phone 1 to perform authentication. The mobile phone 1 transmits an authentication response signal 503 in response to the authentication request signal 502 from the network 2.
[0035]
When the authentication is completed, the network 2 transmits a location registration acceptance signal 504 to the mobile phone 1, and the location registration is completed. The mobile phone 1 enters a standby state. Here, the mobile phone 1 determines that the mobile phone 1 has returned to the service area upon reception of the location registration, and transmits an outgoing radio status report signal 505 to check whether an answering machine message has been recorded when it is out of service area. Thereafter, a call setting signal 506 is transmitted. When the network 2 receives the call setting signal, the network 2 transmits the data indicating whether or not the answering machine message to the mobile phone 1 is registered on the call setting reception signal 507. The mobile phone 1 that has received the call setting acceptance signal does not need to perform further communication, and thus performs a communication end operation. The cellular phone 1 transmits a disconnection request signal 508, and the network 2 that receives this signal transmits a release signal 509. A series of operations is ended by transmitting a release completion signal 510 from the mobile phone 1.
[0036]
In the above description, the case where the mobile phone has moved from outside the service area to the inside has been described as an example, but the present invention can also be applied when the power supply of the mobile phone is switched from off to on.
[0037]
Next, a third embodiment according to the present invention will be described. The present embodiment is characterized in that the incoming call is disconnected at a time set in advance by the user when it is difficult to answer the call. Specifically, the timer count unit 140 counts the time from call termination to call disconnection. If it is known in advance that it is difficult to answer the call, the time until the call is disconnected is set as short as possible, and the answering machine state is quickly established.
[0038]
The operation procedure of this embodiment will be described with reference to the flowchart shown in FIG.
First, the mobile phone that has received an incoming call (step S21 / YES) counts the time N from the incoming call to the disconnection. The count time N can be set by the user. When the timer count value is less than N (step S22 / NO), the user can answer the phone (steps S23 and S24). At the moment when the timer count value reaches N (step S22 / YES), the incoming call is disconnected from the mobile phone (step S25) and there is a missed call (step S26). Thereafter, the mobile phone counts the time until the “call setting” signal in the timer count unit 140, and transmits the “call setting” signal at the moment when the timer count value becomes M. Since the subsequent operation is the same as the operation procedure of the first embodiment described above, description thereof is omitted.
[0039]
The above-described embodiment is a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention. Further, in the embodiment according to the answering machine message confirmation program of the present embodiment, the mobile phone shown in FIG. 1 stores a program controlled by the procedure shown in the flowcharts of FIGS. This is realized by the operation of the mobile phone.
[0040]
【The invention's effect】
As is clear from the above description, when the mobile phone enters the state with a missed call, the first time set in advance is counted, and at the moment when this set time is reached, the mobile phone Communication to confirm presence / absence of telephone message. For this reason, when it is not possible to answer the incoming call, it can be confirmed without a time lag that the caller has left the answering machine message.
[0041]
Further, since the existing “call setting” signal and “call setting acceptance” signal are used to check whether there is an answering machine message in the answering machine service center, it is not necessary to change the system on the network side.
