Description

  The present invention relates to a cellular phone device, an emergency call call return operation method used therefor, and a program therefor, and more particularly, to an incoming call operation for a call back from an emergency call organization such as a police station or a fire station.

  Conventionally, in a mobile phone device, after an emergency situation occurs, after making a call to an emergency call organization such as the police station or fire station, the emergency call is performed to confirm the caller or location. There is a case where a so-called call-back is performed in which a call is returned from the institution to the caller (see, for example, Patent Document 1).

  Moreover, in the mobile phone device, AC (Access Class) of “0” to “9” is allocated in the USIM (Universal Subscriber Identity Module) of the device, and the load on a certain base station increases. When the processing overflows, the network side can perform AC regulation that regulates the outgoing / incoming operation of the mobile phone device for each AC.

  In the cellular phone device to which the AC restriction is applied from the network, all outgoing and incoming calls except the emergency call outgoing operation are disabled until the AC restriction is released. At that time, handling of the incoming call of the emergency call becomes a problem.

  When an emergency call is returned from the mobile phone device side, the caller or location of the call is determined from the emergency call organization within a certain period after the call is disconnected. It is a function that can call the caller again for confirmation.

  FIG. 6 shows the operation of the emergency call return incoming call. Hereinafter, an operation for calling back an emergency call in a conventional mobile phone device will be described with reference to FIG.

  First, the mobile phone device performs a call operation to the emergency call organization during AC regulation (step S41 in FIG. 6), and performs a call termination operation to disconnect the emergency call (step S42 in FIG. 6).

  Thereafter, when the mobile phone device receives a paging signal that is a call incoming call from the emergency call organization (step S43 in FIG. 6), the mobile phone device has a specification that responds to paging even when the device is in AC regulation (step S44 in FIG. 6). The incoming call operation is performed in response to the paging signal (step S45 in FIG. 6).

  On the other hand, if the mobile phone device has a specification that does not respond to paging during AC regulation (step S44 in FIG. 6), the mobile phone device does not react to the paging signal and does not perform the incoming operation (step S46 in FIG. 6).

JP 2005-026803 A

  The above-described conventional mobile phone device has the following problems with respect to the emergency call return incoming call that occurs during AC regulation.

  In the case of a mobile phone device that can accept a call in response to paging even during AC regulation to respond to an emergency call return call, in a country where there is no emergency call return call system, Regardless, problems such as incoming calls will occur. In countries where there is an emergency call return system such as Japan, the network side restricts incoming calls from non-emergency calls other than emergency calls and does not send paging signals. Since the distribution process is performed in the network so that only the paging signal for the emergency call return incoming call is transmitted to the mobile phone device, there is no problem.

  On the other hand, when the mobile phone device does not respond to paging and does not perform incoming calls during AC regulation, it is used for paging incoming calls for emergency calls in countries with emergency call return systems such as Japan. Does not respond, and a problem occurs that the incoming call cannot be received.

  In other words, when a mobile phone device that conforms to the 3GPP (3rd Generation Partnership Projects) regulations is in an AC-restricted state, any outgoing / incoming operation other than an emergency call outgoing operation cannot be performed. There is a problem that the emergency call does not respond to the incoming call.

  On the other hand, if the incoming call operation is possible even during AC regulation because it responds to an emergency call back incoming call, the network side sends a paging signal to report the incoming call from a general telephone while the AC is regulated. Except for the case where it is restricted, there is a problem that, although it is under AC restriction, it reacts to a paging signal from a general telephone and performs an incoming operation.

  In particular, in countries where there is no emergency call return system, the network sends only paging signals for emergency call return calls, and sends a paging signal that reports incoming calls from regular phones with restrictions. Since the operation such as “No” is not performed, there is a problem that the incoming operation is performed in response to the paging signal of the general telephone even though the AC is being regulated.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mobile phone device capable of solving the above-described problems and solving the problem of an emergency call return incoming call during AC regulation, an emergency call return incoming call operation method used therefor, and a program thereof. It is to provide.

A cellular phone device according to the present invention is a cellular phone device in which AC regulation for regulating outgoing / incoming operations for each AC (Access Class) in a USIM (Universal Subscriber Identity Module) is performed.
During the implementation of the AC regulation, there is provided means for switching whether or not to perform an emergency call return operation after the call with the emergency call organization is disconnected from the own device side depending on the country .

The emergency call call return incoming call operation method according to the present invention is an emergency call call return incoming call used for a cellular phone device in which AC control for restricting outgoing / incoming operation is performed for each AC (Access Class) in USIM (Universal Subscriber Identity Module). A method of operation,
Whether or not the mobile phone device performs an incoming call operation of an emergency call after a call with an emergency call organization is disconnected from the mobile phone device side depending on a country during implementation of the AC regulation. Switching process is being executed.

A program according to the present invention is a program to be executed by a central processing unit of a mobile phone device in which AC regulation for regulating outgoing / incoming operation is performed for each AC (Access Class) in USIM (Universal Subscriber Identity Module),
During the implementation of the AC regulation, by country, that the call of the emergency call engine includes a process for switching whether or not the emergency call-back of the incoming call operation or implementing / implemented after being disconnected from the mobile collector side Features .

  That is, the mobile phone device of the present invention refers to the MCC (Mobile Country Code) in the broadcast information transmitted from the network, and uses the AC ( If it is used in a country where there is no emergency call back incoming call system, the incoming call operation is not performed during the AC regulation, so that the emergency operation during the AC regulation is performed. It is possible to solve the problem of incoming call back.

  In other words, in the mobile phone device of the present invention, in a country where there is a system for receiving an emergency call by switching whether or not to perform an incoming call operation under AC regulation depending on the country where the user of the device is present, It is possible to respond to an emergency call return incoming call in response to a received paging signal even if it is under AC restriction, and it is under AC restriction in a country where there is no emergency call return incoming call system. For example, it is possible to comply with 3GPP (3rd Generation Partnership Projects) AC regulations without reacting to the received paging signal.

  Here, the AC restriction is to restrict the outgoing / incoming operation of the mobile phone device for each AC (“0” to “9”) in the USIM (Universal Subscriber Identity Module). When a call with the emergency call organization is disconnected from the mobile phone device side, the emergency call organization confirms the caller and location of the call again within a certain period after the call is disconnected. An incoming call for a caller.

  In the first mobile phone device of the present invention, referring to the MCC in the notification information received from the network, it is confirmed whether or not the country where the user of the device is the country where the system for receiving the emergency call is received. However, in countries where there is a system for receiving incoming calls for emergency calls, even if AC regulation is in effect, the incoming call operation is performed when a paging signal reporting that there is an incoming call to the device itself, and the emergency call is executed. In a country where there is no call back system, control is performed so that the incoming call operation is not performed when a paging signal is received during AC regulation.

  In the second mobile phone device of the present invention, not only MCC but also MNC (Mobile Network Code) is referenced, and even if it is detected by the MCC that there is a system for calling back an emergency call, When it is detected by the MNC that the carrier is not compatible with the emergency call return incoming call, control is performed so that the incoming call operation is not performed without reacting to the received paging signal.

  In the above-described first mobile phone device of the present invention, only the MCC in the broadcast information is referred to, and the incoming call operation is performed based on the paging signal under AC regulation according to the presence or absence of the emergency call return incoming call system at the location. However, even in countries where there is an emergency call return system, some carriers do not support the emergency call return system, and there is an emergency during AC regulation. Rather than sending only paging for incoming calls from the base station to the mobile phone device, a paging signal that reports the incoming call is sent to the mobile phone device that is AC-regulated for all connection requests including general calls. It is also possible that

  Therefore, in the second mobile phone device of the present invention, when the MNC detects that the carrier is compatible with the emergency call return incoming call, the incoming call operation is performed in response to the received paging signal. So that it is controlled.

  In the third cellular phone device of the present invention, a paging signal is received within a certain period (predetermined period) in which a call can be assumed after calling the emergency call organization and terminating the call. In this case, the incoming operation is performed in response to the paging signal, and when the paging signal is received after the above-mentioned fixed period has passed, the incoming operation is not performed without reacting to the paging signal. Yes.

  In the first and second mobile phone apparatuses of the present invention described above, the operation of whether or not to perform the incoming call operation in response to the paging signal received during the AC regulation with reference to the MCC or MNC is distributed. In the third cellular phone device according to the present invention, when a paging signal is received within a certain period of time when an incoming call can be assumed after the outgoing call to the emergency call organization is terminated, the incoming call is made in response to the paging signal. Since the operation is performed, the MCC and MNC reference processing becomes unnecessary.

  The above-described call back / incoming operation methods in the first to third mobile phone devices of the present invention can also be applied to each other, and by combining these methods, they are generated as compared with the cases where each is independent. This makes it possible to reduce the problems that occur.

  By adopting the above-described configuration and operation, the present invention provides an effect that it is possible to solve the problem of emergency call return incoming calls during AC regulation.

  Next, embodiments of the present invention will be described with reference to the drawings.

Since the operation of each part in the mobile phone device 1 is the same as that of a conventional mobile phone device, description thereof is omitted.

  FIG. 2 is a flowchart showing an emergency call return incoming operation during AC (Mobile Country Code) regulation of the mobile phone device 1 according to the first embodiment of the present invention. With reference to these FIG. 1 and FIG. 2, the operation for calling back an emergency call during the AC regulation of the cellular phone device 1 according to the first embodiment of the present invention will be described. The processing shown in FIG. 2 can be realized by the control unit 13 executing the program in the memory 15.

  Here, the AC restriction is to restrict the outgoing / incoming operation of the mobile phone device for each AC (“0” to “9”) in the USIM (Universal Subscriber Identity Module). When a call with the emergency call organization is disconnected from the mobile phone device side, the emergency call organization confirms the caller and location of the call again within a certain period after the call is disconnected. An incoming call for a caller.

  First, the mobile phone device 1 performs an outgoing call operation to the emergency call organization during AC regulation (step S1 in FIG. 2), and then performs a call termination operation to disconnect the emergency call (step S2 in FIG. 2).

  Thereafter, when the mobile phone device 1 receives a paging signal that is a call incoming call from the emergency call organization (step S3 in FIG. 2), the mobile phone device 1 displays an MCC (Mobile Country Code) according to the notification information acquired in advance from the network. Referring to FIG. 2, it is confirmed whether the country in which the user of the device is present is a country with a system for receiving an emergency call back (step S4 in FIG. 2).

  If the received MCC indicates that the country has an emergency call return incoming call system, the mobile phone device 1 performs an incoming call operation in response to the paging signal (step S5 in FIG. 2). If the received MCC indicates that the country does not have an emergency call return system, the incoming operation in response to the paging signal is not performed (step S6 in FIG. 2).

  As described above, in this embodiment, referring to the MCC in the notification information, it is confirmed whether the country where the user of the mobile phone device 1 is a country where there is a system for calling back an emergency call. By determining whether or not an incoming operation is performed in response to the paging signal, it is possible to solve the conventional problem of the emergency call return incoming call during the AC regulation.

  In other words, in this embodiment, in countries where there is an emergency call return system, even if the AC is being regulated, it is possible to respond to an emergency call return call in response to the received paging signal. In a country where there is no call return system, it is possible to comply with the 3GPP (3rd Generation Partnership Projects) AC regulation provisions without reacting to the received paging signal if it is under AC regulation.

  FIG. 3 is a flowchart showing an emergency call return incoming operation during AC regulation of the mobile phone device according to the second embodiment of the present invention. Since the mobile phone device according to the second embodiment of the present invention has the same configuration as the mobile phone device 1 according to the first embodiment of the present invention shown in FIG. 1, the present invention will be described with reference to FIGS. An emergency call return incoming operation during AC regulation of the mobile phone device according to the second embodiment of the invention will be described. Note that the processing shown in FIG. 3 can be realized by the control unit 13 executing the program in the memory 15.

  First, the mobile phone device 1 performs an outgoing call operation to the emergency call organization during AC regulation (step S11 in FIG. 3), and then performs a call termination operation to disconnect the emergency call (step S12 in FIG. 3).

  Thereafter, when the mobile phone device 1 receives a paging signal that is a call incoming call from the emergency call organization (step S13 in FIG. 3), the mobile phone device 1 refers to the MCC according to the notification information acquired in advance from the network, and uses the user of the device itself. It is confirmed whether or not the country in which there is a country with a system for receiving and receiving emergency calls (step S14 in FIG. 3).

  If the mobile phone device 1 is a country where the received MCC has an emergency call return system, the mobile phone device 1 also refers to the MNC (Mobile Network Code), and the MCC has an emergency call return system. Even if it is detected that the country is a certain country, it is confirmed whether the MNC is a carrier corresponding to the emergency call return incoming call (step S15 in FIG. 3).

  If the mobile phone device 1 indicates that the MNC is a carrier corresponding to the emergency call return incoming call, the mobile phone device 1 performs the incoming call operation in response to the above paging signal (step S16 in FIG. 3) and has received it. If the MCC indicates that the country does not have an emergency call return system, or if the MNC indicates that it is not a carrier for emergency call return calls, the incoming call in response to the above paging signal The operation is not performed (step S17 in FIG. 3).

  In the first embodiment of the present invention described above, only the MCC in the broadcast information is referred to, and in a country where there is a system for calling back an emergency call, it responds to the received paging signal even if it is under AC regulation. Even if the country has an emergency call return system, some carriers do not support the emergency call return system. Rather than sending only paging for incoming calls from the base station to the mobile phone device 1, it sends a paging signal that reports the incoming call to the mobile phone device 1 under AC regulation for all connection requests including general calls. It is also possible that

  Therefore, in this embodiment, not only the MCC but also the MNC is referred to, and even if the MCC indicates that the country has a system for receiving an emergency call return call, the MNC can receive an emergency call call return call. When it indicates that the carrier is not compatible, the incoming call operation is not performed without reacting to the received paging signal. In this embodiment, when the MNC indicates that it is a carrier corresponding to the emergency call return incoming call, the incoming call operation is performed in response to the received paging signal. Similar to the first embodiment, it is possible to solve the conventional problem of the emergency call return incoming call during the AC regulation.

  FIG. 4 is a flowchart showing an emergency call return incoming operation during AC regulation of the mobile phone device according to the third embodiment of the present invention. Since the mobile phone device according to the third embodiment of the present invention has the same configuration as the mobile phone device 1 according to the first embodiment of the present invention shown in FIG. 1, the present invention will be described with reference to FIGS. An emergency call return incoming operation during AC regulation of the mobile phone device according to the third embodiment of the invention will be described. The process shown in FIG. 4 can be realized by the control unit 13 executing the program in the memory 15.

  First, the mobile phone device 1 performs a call operation to the emergency call organization during AC regulation (step S21 in FIG. 4), and performs a call termination operation to disconnect the emergency call from the mobile phone device 1 (step 4 in FIG. 4). S22). The cellular phone device 1 uses the disconnection operation as a trigger to start an emergency call call back timer in which a fixed period (a predetermined fixed period) in which an incoming call is expected from the emergency call disconnection is set (see FIG. 4 step S23).

  After that, the cellular phone device 1 receives a paging signal that is a call incoming call from the emergency call organization (step S24 in FIG. 4), but the emergency call call back timer is before time-out (expiration) (step S25 in FIG. 4). ), An incoming call operation is performed in response to the paging signal (step S26 in FIG. 4).

  When the call back timer for the emergency call is after a time-out (expiration) (step S25 in FIG. 4), the cellular phone device 1 does not react to the paging signal and does not perform the incoming operation (step S27 in FIG. 4).

  In the first and second embodiments of the present invention described above, the operation of whether or not to perform the incoming operation in response to the paging signal received during AC regulation with reference to the MCC or MNC is distributed. When a paging signal is received within a certain period of time that can be expected to be returned after calling the calling organization and ending the call, an incoming operation is performed in response to the paging signal, and the certain period has passed. When a paging signal is received later, it does not react to the paging signal and does not carry out the incoming call operation. Therefore, as in the first embodiment of the present invention described above, an emergency call is called during AC regulation. The conventional problem of return incoming calls can be solved. However, in this case, MCC or MNC reference processing is not required.

  FIG. 5 is a flowchart showing an emergency call return incoming operation during AC regulation of the mobile phone device according to the fourth embodiment of the present invention. Since the mobile phone device according to the fourth embodiment of the present invention has the same configuration as the mobile phone device 1 according to the first embodiment of the present invention shown in FIG. 1, the present invention will be described with reference to FIGS. An emergency call return incoming operation during AC regulation of a mobile phone device according to a fourth embodiment of the invention will be described. Note that the processing shown in FIG. 5 can be realized by the control unit 13 executing the program in the memory 15.

  First, the mobile phone device 1 performs a call operation to the emergency call organization during AC regulation (step S31 in FIG. 5), and performs a call termination operation to disconnect the emergency call from the mobile phone device 1 (step S32 in FIG. 5). ). The cellular phone device 1 uses the disconnection operation as a trigger to start an emergency call call-back timer in which a fixed period (predetermined fixed time) in which a call-back incoming call is expected after disconnecting the emergency call is set (see FIG. 5 step S33).

  Thereafter, the cellular phone device 1 receives a paging signal that is a call return from the emergency call organization (step S34 in FIG. 5), but the emergency call return timer is after a timeout (expiration) (step S35 in FIG. 5). ), Does not react to the paging signal and does not perform the incoming call operation (step S38 in FIG. 5).

  When the call back timer for the emergency call is before time-out (expiration) (step S35 in FIG. 5), the mobile phone device 1 refers to the MCC from the notification information acquired in advance from the network, and there is a user of the device itself. It is confirmed whether or not the country has a system for receiving an emergency call back (step S36 in FIG. 5).

  If the received MCC indicates that the country has no emergency call back incoming call system, the mobile phone device 1 does not respond to the paging signal and does not perform the incoming call operation (step S38 in FIG. 5). ). If the received MCC indicates that the country has a system for receiving an emergency call back, the mobile phone device 1 performs an incoming operation in response to the paging signal (step in FIG. 5). S37).

  As described above, in this embodiment, the method of referring to the MCC according to the first embodiment of the present invention and the method of performing timer monitoring according to the third embodiment of the present invention are combined. As in the first embodiment of the present invention, it is possible to solve the conventional problem of the incoming call return of the emergency call during the AC regulation, and to reduce the problems that occur as compared with the case where each of these methods is independent. It becomes possible to make it.

  In the method of referring to MCC according to the first embodiment of the present invention, a paging signal from a general telephone is also transmitted on the network side even in the country where there is a system for calling back an emergency call even if the AC is regulated. In such a case, there arises a problem that the incoming call operation is performed even though the AC is regulated. However, by combining the timer monitoring method according to the third embodiment of the present invention, even if a paging signal is received from a general telephone, if the emergency call return timer has expired, the paging signal is changed. Does not respond and does not perform incoming calls.

  Further, in the method of performing timer monitoring according to the third embodiment of the present invention, when a paging signal is received from a general telephone before the emergency call return timer expires, an emergency call return incoming call system is provided. Regardless of whether or not there is an incoming call. However, in combination with the method of referring to the MCC according to the first embodiment of the present invention, even in a country where there is no emergency call return system, even before the emergency call return timer expires, the paging signal Does not respond to incoming calls.

  It should be noted that the above-described emergency call return operation during AC regulation according to the first to fourth embodiments of the present invention can be applied to each other and is not limited to the above-described embodiments.
