DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal apparatus for making and receiving calls by exchanging predetermined control signals, for example, a PDC system, N-CDMA (Narrow Band Code Div.).
ision Multiple Access) system and next generation W-CDMA
The present invention relates to a communication terminal device which is suitably applied to a communication terminal device of a general mobile radio communication system such as a (wide band code division multiple access) system and enables smooth call control. Here, as an example of the communication terminal device, there is a voice communication terminal device such as a mobile phone terminal.

[0002]

2. Description of the Related Art FIG. 4 shows an outline of a configuration of a mobile radio communication system. In the figure, a first mobile communication terminal device (hereinafter referred to as “mobile station”) M1 such as a mobile phone terminal is a first mobile communication terminal device.
Is located in the wireless area of the base station B1 and the second mobile station M
2 is located in the wireless area of the second base station B2.

[0003] The first and second base stations B1 and B2 are connected to an exchange EX, and the first and second mobile stations M1 and M2.
Are respectively connected to the first and second base stations B1 and B2 via the exchange EX. Here, in order to simplify the description, the configuration example shown in FIG.
1 and B2 are under the control of one exchange EX.

FIG. 5 shows a flow of call connection control for connecting two mobile stations. When the user of the first mobile station M1 makes a call to the second mobile station M2, the user of the first mobile station M1 inputs identification information (for example, a telephone number) of the second mobile station M2. A connection key (ON key) is pressed to make a call request (a setup signal including the identification information is transmitted to the network side) (step 5-1). The exchange EX controls the outgoing connection of the mobile station M1 via the base station B1, and sends a call request confirmation to the mobile station M1 (step 5-2). At the same time, an incoming call request is transmitted to the mobile station M2 via the base station B2 (step 5-3).

[0005] In response to the incoming request from the exchange EX, the mobile station M2 transmits an incoming request confirmation to the exchange EX (step 5-4). After sending a call request confirmation to the mobile station M1, the exchange EX performs a synchronization establishment process for a telephone call, and also performs a synchronization establishment process for the mobile station M2 after receiving the incoming request confirmation.

The mobile station M2 emits a ringing tone (bell tone) when a call becomes available (step 5-5), and the mobile station M1 emits a ringback tone indicating that the mobile station is ringing (step 5-5). Step 5-6). When a response such as an off-hook operation (ON key operation) is performed in the mobile station M2, the mobile station M1 and the mobile station M2 are set in a call state (step 5-8).

[0007] At this time, while the outgoing connection process from the mobile station M1 to the mobile station M2 is being performed (after the setup signal is transmitted at the time of the call request), the mobile station M1 and the mobile station M2 are connected to another communication terminal apparatus. , A busy tone is returned to another communication terminal device that has called the mobile station M1 or the mobile station M2. Therefore, if the mobile station M2 makes a call request to the mobile station M1 before the mobile station M2 receives a call request from the mobile station M1 to a call termination request, for example, both the mobile station M1 and the mobile station M2 are A busy state is established and a connection is not established.

[0008]

When an attempt is made to originate a call from the mobile station M1 to the mobile station M2 or vice versa, the possibility of simultaneously calling each other is extremely low in the usual case. However, when the mobile station M1 and the mobile station M2 that were in a call are disconnected due to some failure (for example, deterioration of the radio wave environment) and the call cannot be maintained, the mobile station M1 and the mobile station M2 try to talk again with each other. It is very likely that both will make a call at the same time. In such a case, if a call is made on both sides at the same time, both sides are busy and the calling process is repeated on both sides to retry the call many times, and the state of no connection is repeated.

According to the present invention, even when an outgoing call is attempted after a communication disconnection, the outgoing call control is performed so that the mobile stations can make and receive calls smoothly, and a situation in which the mobile stations are not connected to each other is prevented from being repeated. It is an object of the present invention to provide a communication terminal device capable of performing such operations.

[0010]

There is provided transmission control means for restricting outgoing connection to the number stored in the history information storage means.

[0011] Further, (2) there is provided a call restricting means for enabling a call to another communication terminal device after a lapse of a predetermined time from the disconnection of communication (call) with another communication terminal device. When the communication (call) is disconnected, the calling is uniformly regulated for a predetermined time (regardless of the call requesting party). Preferably, it is most preferable to restrict the outgoing call for a predetermined time only for the call to the communication terminal device that was communicating (calling) before the disconnection. Radiation can be prevented.

(3) In a communication terminal device for making a call request by transmitting a signal including identification information of another communication terminal device to the network side, the identification of the communication terminal device of the immediately preceding communication (call) partner is performed. A storage unit for storing information, and a request for transmitting a signal including the stored identification information to the network side is not made before a predetermined time elapses after disconnection of communication (call). Is provided with call control means for enabling a call request for transmitting a signal including the stored identification information to the network side. According to this configuration, it is possible to efficiently regulate the outgoing call to the same communication (call) partner for a predetermined time after the disconnection of the communication (call).

(4) In the communication terminal device of (3), the control of the call restricting means is enabled or disabled between the communication terminal device and the communication terminal device of the communication (call) during communication (call). And determining means for validating the control of the call restricting means when it is determined to be valid. It is possible to mutually recognize the communication (call) partner and the validity / invalidity of the call restriction.

(5) The apparatus further comprises selection setting means for selecting and setting any one of two or more different times as the predetermined time according to a predetermined algorithm. The selection according to the predetermined algorithm may be a selection setting unit that performs a random selection, a selection according to a communication partner, a selection for each communication (call), and the like.

[0015]

FIG. 1 shows the configuration of a transmission control function in a communication terminal device according to the present invention. Hereinafter, each functional block constituting the transmission control function will be described. The first timer 1-11 is provided with a disconnect key (O
FF key) 1-1 is pressed, or the connection key (ON) which is operated at the start of a call after the communication for predetermined disconnection processing with the network side is completed or when the control unit determines that a call can be made. The time until the key 1-2 is pressed is counted, and the time is counted as a predetermined expiration time (time-out time) T1.
Is output to the control unit 1-10, indicating whether or not the number exceeds the limit.

The second timer 1-12 counts an elapsed time since the connection key (ON key) 1-2 for starting a call is pressed, and the elapsed time is a predetermined expiration time (time-out time). ) A signal indicating whether or not T2 is exceeded is output to the control unit 1-10.

The first and second timers 1-1 are used.
1, 1-12 each comprise a selection setting means for selecting and setting any one of two or more different timeout times according to a predetermined algorithm, and according to the predetermined algorithm, random selection, selection according to a communication partner, or communication. A configuration in which a predetermined timeout time is set by selection or the like for each (call) can be adopted.

The outgoing number memory 1-3 stores the outgoing number to the other party that is currently input to make a call.
The transmission history memory 1-4 stores the currently input transmission number 1
The identification information (for example, telephone number) of the other party that was input immediately before is stored. The incoming call history memory 1-5 stores identification information (for example, a telephone number) of the mobile station that is the caller of the incoming connection performed immediately before the current outgoing call operation. The outgoing / incoming call history memory 1-6 stores history information indicating whether the immediately preceding call was an outgoing call from the own device or an incoming call from the other device.

The selector section 1-8 selects a number stored in the transmission history memory 1-4 based on the information in the transmission / reception history memory 1-6 when the last connection is a transmission connection. If the previous connection is an incoming connection, the number stored in the incoming call history memory 1-5 is selected and output to the comparator section 1-9. History information storage for storing identification information (for example, telephone number) of the immediately preceding connection partner by the transmission history memory 1-4, the reception history memory 1-5, the transmission / reception history memory 1-6, and the selector unit 1-8. Means (storage means) are configured.

The outgoing call mode setting section 1-7 negotiates the next outgoing call control mode with the communication terminal device of the other party when a call connection is established (during communication). Here, as the transmission control mode, “mode 0” (transmission control is disabled) for immediately permitting transmission and “mode 1” (transmission restriction control) for permitting transmission after the expiration time of the second timer 1-12. And two modes of “valid”) are set by negotiation so that the own apparatus and the other apparatus have an exclusive relationship (for example, if the own apparatus is “mode 0”, the other apparatus is “mode 1”). The setting mode is output to the control unit 1-10.

The comparator section 1-9 includes a selector section 1-
The telephone number selected in Step 8 is compared with the current input number stored in the calling number memory 1-3, and a signal indicating whether or not the numbers match is output to the control unit 1-10.

The control unit 1-10 includes a transmission mode setting unit 1-
7 and the first timer after the disconnection key (OFF key) is operated, when the communication for the predetermined disconnection processing with the network side is completed, or when the control unit determines that the call can be made. Immediately from the signal indicating the elapsed time by 1-11, the signal indicating the elapsed time after the operation of the connection key (ON key) by the second timer 1-12, and the comparison result of the calling number by the comparator 1-9. Allow outgoing calls or secondary
Until the timer 1-12 reaches the expiration time T2, the transmission is restricted, and during that time, control is performed to determine whether to wait for an incoming call from the partner device.

FIG. 2 shows a flow of the transmission control using the timer according to the present invention. If the radio link between one mobile station and the base station is disconnected due to the temporary deterioration of the radio link between the two mobile stations during a call, the mobile station is disconnected. The users try to re-call each other. However, in the call connection control at the time of the previous call, when the mobile stations are connected to each other, the transmission control mode of "mode 0" or "mode 1" becomes an exclusive relationship by negotiation between the mobile stations. It is set as follows.

When one of the mobile stations detects the disconnection of the call (step 2-1), the first timer starts counting (step 2-2). When the user of this mobile station tries to connect again, he or she inputs the telephone number of the mobile station of the other party to which the call has been made so far, and uses the connection key (O) to perform a calling process.
When the N key is operated, a connection key (ON key) operation signal is input (step 2-3). When the connection key (ON key) operation signal is input, the first timer reaches the count T1 and expires. It is determined whether or not it has been performed (step 2-4).

If the first timer has expired, it is determined that sufficient time has elapsed since the end of the previous call, the call is accepted, and the call connection process is immediately performed (step 2-11). ). However, if the first timer has not expired, the connection key (ON
Key) operation is determined to have been performed, and the process proceeds to the following determination processing.

In the next determination processing, it is determined whether or not the currently input calling number matches the number of the other party with whom the communication was made immediately before (step 2-5). In this determination, it is checked whether the previous connection was an outgoing connection or an incoming connection based on the contents of the outgoing / incoming history memory, and if the connection was an outgoing connection, the previous connection stored in the outgoing history memory is determined. A comparison is made between the outgoing number, the number of the previous caller stored in the incoming call history memory if the connection was an incoming call, and the currently input outgoing number.

If the currently entered calling number does not match the number of the communication partner with whom it was communicating immediately before, it means that the call is being made to another person different from the previous connection partner. Perform transmission processing (step 2-1)
1). If the currently input calling number matches the number of the communication partner that was communicating immediately before, the process proceeds to the next determination process.

In the next determination processing, it is determined whether the mode information set in the transmission mode setting unit by the negotiation at the time of the previous connection establishment is "mode 0" or "mode 1" (step 2). 6). If "mode 0" has been set, outgoing connection processing is immediately performed (step 2-11). At this time, “mode 1” is set in the communication terminal apparatus on the other side.

In the communication terminal device set to "mode 1", the second timer starts counting almost simultaneously with the operation of the connection key (ON key) (step 2-7), and reaches the count value T2 and expires. During this period, it is determined only whether there is an incoming call (steps 2-8 and 2-9), and if there is an incoming call, an incoming call operation is accepted, and it is possible to shift to a talking state (step 2-10).

Since the communication terminal device of the communication partner immediately before the communication terminal device set to "mode 1" is set to "mode 0", if reconnection is attempted, the outgoing connection process is immediately performed. This should be done, and a smooth connection will be made without calling collision with the communication terminal device set to “mode 1”. And "mode 1"
The communication terminal device set to the state in which transmission is possible after the expiration time T2 of the second timer elapses (step 2-).
11).

As described above, the communication terminal device set to "mode 0" performs the outgoing connection process immediately after the connection key (ON key) is pressed, but the communication terminal device set to "mode 1". Means that even if the connection key (ON key) is pressed,
For a call to the previous connection destination, the call is permitted after the second timer times out, so that an invalid call is prevented and a smooth call connection is performed.

FIG. 3 shows a flow of transmission control performed between two mobile stations. In the figure, it is assumed that the first mobile station M1 has been set to "mode 0" and the second mobile station M2 has been set to "mode 1" by negotiation at the time of the previous connection establishment. Here, it is assumed that the connection between the two mobile stations M1 and M2 is disconnected and a disconnection key (OFF key) operation signal is input (step 3-1).

Before the expiration time T1 of the first timer elapses, the mobile station M1 receives the telephone number of the mobile station M2 that was the immediately preceding connection partner, and receives the connection key (ON key) operation signal. (Step 3-2) Similarly, before the expiration time T1 of the first timer elapses, the mobile station M2 receives the connection key (ON key) operation signal by inputting the number of the mobile station M1 that was the immediately preceding connection partner. Is entered (Step 3
-3).

In this case, since the mobile station M1 is set to "mode 0", the mobile station M1 immediately performs the calling connection process (step 3-4). On the other hand, since “mode 1” is set, the mobile station M2 is in a call waiting state until the second timer reaches the expiration time T2 (step 3-5,
Step 3-6). The outgoing connection from the mobile station M1 is smoothly connected to the mobile station M2 because the mobile station M2 is waiting for an incoming call, and shifts to a call state (step 3-).
7).

If no transmission is made from the mobile station M1 to the mobile station M2, the mobile station M2 determines the expiration of the second timer (step 3-6), and the expiration time T2 of the second timer. Later, transmission to the mobile station M1 is permitted (step 3-8), and the mobile station M2 shifts to a call state by outgoing connection to the mobile station M1 (step 3-9).
