Description

  The present invention relates to a wireless communication terminal capable of communicating with a plurality of communication systems.

  There is a mobile terminal that performs different processing depending on the type of data communication when a voice call is received during data communication (see, for example, Patent Document 1). When receiving an incoming voice call during data communication, the mobile terminal transmits an incoming voice call notification response to the base station according to the management table. When the base station receives from the mobile terminal a voice incoming notification response indicating that this incoming call notification is to be sent, the base station sends a predetermined guidance to the transmitting terminal of the voice communication and confirms the voice incoming notification response to the mobile terminal. Send.

JP 2002-64867 A

  Since the mobile terminal described in the prior art performs voice communication and data communication by one communication method, even if it is set not to notify the user of incoming calls during data communication, data communication is not performed. In order to resume, it is necessary to perform a voice call notification response to the base station.

  On the other hand, in a communication terminal using a plurality of communication systems, when a voice incoming notification is received when it is set not to perform incoming notification during data communication, a voice incoming notification response is not sent from the communication terminal. Data communication can be resumed. In general, more power is consumed when data is transmitted from the communication terminal to the base station than when data is received from the base station. Therefore, power consumption can be suppressed by not responding to the base station. However, if an incoming call notification response is not sent from the communication terminal to the base station, the base station continues to transmit the incoming voice call notification, and the communication terminal receives the incoming voice call notification many times for one call. In this case, if the communication terminal counts the number of incoming calls every time it receives a voice call notification, it actually notifies the user that there were multiple incoming calls even though there was only one incoming call. There is a possibility that the number cannot be known and the usability is deteriorated.

  Therefore, an object of the present invention is to improve the usability of a communication terminal using a plurality of communication systems.

  The object is achieved by the invention described in the claims.

  According to the present invention, usability of a communication terminal using a plurality of communication systems can be improved.

  FIG. 1 is a diagram illustrating a wireless communication system. Reference numeral 100 denotes a wireless communication terminal such as a mobile phone or a PDA (Personal Digital Assistance). Reference numeral 101 denotes a base station of a first communication system which is a cellular telephone (PHS) communication system such as CDMA (Code Division Multiple Access). 101a is a service area covered by the base station 101, and 102 is a communication network of the first communication system to which the base station 101 and other base stations are connected. The wireless communication terminal 100 can perform voice call, data communication, and FAX communication with other wireless communication terminals and landline phones within the service area 101a.

  Reference numeral 103 denotes a base station of a second communication system such as a wireless LAN or 1x EV-DO (Evolution Data Only). 103a is a service area covered by the base station 103, and 104 is a communication network of a second communication system connecting the base station 103 and other base stations. The wireless communication terminal 100 can perform high-speed data communication as compared with the first communication system by performing communication using the second communication system.

  In the wireless communication system shown in FIG. 1, the communication network 102 of the first communication system and the communication network 104 of the second communication system are independent of each other. However, the communication network 102 and the communication network are connected via the Internet network or the like. 104 may be connected.

  FIG. 2 is a diagram illustrating a configuration of the wireless communication terminal. The control unit 201 is, for example, a CPU (Central Processing Unit), and performs operation control in each component of the wireless communication terminal described below and processing of input information. For example, data is stored in the storage unit 206, status or data is displayed on the display unit 207, sound is input from the microphone 208, sound is output from the speaker 209, or the external connection unit 211 is connected. Control to send / receive data to / from PC.

  The first communication unit 202 transmits / receives a signal to / from a base station using the first communication system such as the base station 101 via the transmission / reception unit 204 and the antenna 205. The second communication unit 203 transmits / receives a signal to / from a base station using the second communication system such as the base station 103 via the transmission / reception unit 204 and the antenna 205. In this wireless communication terminal, the transmission / reception unit 204 and the antenna 205 are shared and used in the first communication system and the second communication system, but may be provided separately.

  The storage unit 206 stores a program used when the control unit 201 performs control and processing, and data such as user data. The display unit 207 is a display such as a liquid crystal display, for example, and displays a remaining battery level, out-of-service display, mail, and the like. The input unit 210 includes a numeric keypad and cursor keys, and is used when a user inputs data or selects processing. The input unit 210 may be a touch panel system that allows a user to input characters and numbers by touching the display using a pen or a finger.

  FIG. 3 shows the first communication unit 202 and the second communication when the wireless communication terminal 100 performs data communication using the second communication system in the cover area 101a of the base station 101 and the cover area 103a of the base station 103. FIG. 6 is a diagram illustrating an operation of a unit 203.

  As shown in T301 of FIG. 3, when the second communication unit is communicating with the base station 103, the first communication unit 202 is not assigned the resource of the transmission / reception unit 204, so the base station The capturing process 101 is not performed, and a stop state is entered.

  When the predetermined time has elapsed and T302 in FIG. 3 is reached, the control unit 201 stops the communication operation of the second communication unit 203, allocates the resources of the transmission / reception unit 204 to the first communication unit 202, and the first communication unit The operation of 202 is started. The wireless communication terminal 100 starts communication with the base station 101 by the first communication system, and confirms whether or not the base station information is updated or the mobile station is called.

  Next, processing when the wireless communication unit 100 performs reception processing in the first communication unit 202 will be described using FIG. FIG. 4 is a sequence diagram of the first embodiment showing the operation of the wireless terminal device 100 at T303 in FIG.

  When the first communication unit 202 is in an operating state under the control of the control unit 201, a process for capturing the state of the base station that communicates with the first communication system and an incoming call notification indicating that there is a call to the own station It is confirmed whether or not it is transmitted from the station (402).

  If there is no call, an incoming flag indicating that there is no incoming call is set to FALSE (403), the reception process is terminated, and a process for stopping the first communication unit 202 is started (417). When the first communication unit 202 stops, the control unit 201 causes the second communication unit 203 to start operation, and resumes data communication using the second system.

  When there is a call from the base station 101, it is confirmed whether the incoming call is accepted (404). When there is a call from the base station, the user selects in advance using the input unit 210 whether to accept the call and notify the incoming call.

  When the user is communicating with the second communication system and has made a setting for accepting a call to the first communication system, the incoming process of the first communication system is performed (404). The wireless communication terminal 100 starts negotiation with the base station 101 and performs connection processing (409). When receiving information such as the telephone number of the caller transmitted from the base station 101 (410), the wireless communication terminal 100 starts ringing (411). If the user does not respond (412) after the ringing is started, when a disconnection request 413 is transmitted from the base station 101, a call disconnection process with the base station 101 is performed (416). On the other hand, when the user responds, the mobile device 100 enters a call state (414) in the first system, and performs a disconnection process (416) when the call ends.

  After the disconnection process, the first communication unit 202 is stopped (417), and high-speed data communication using the second system is resumed.

  The operation when the user is set not to accept the call of the first system during the communication of the second system will be described with reference to FIGS.

  5 and 6 are diagrams illustrating the relationship between the call from the base station 101 and the wireless communication terminal 100. FIG. 5, the same reference numerals as those in FIGS. 2 and 3 indicate the same functions. 6, the same reference numerals as those in FIGS. 2, 3, and 5 indicate the same functions.

  When there is a call from the base station 101 while the first communication unit 202 is operating (304), the control unit 201 determines an incoming flag that indicates whether there was an incoming call when the first communication unit 202 operated last time. (405). If there was no previous incoming call (the incoming flag is FALSE), the incoming flag secured in the storage unit 206 is set to TRUE (406), and the number of incoming calls secured in the storage unit 206 is added (407). Next, as shown at 501, the fact that there is an incoming call and the number of incoming calls are displayed on the display unit 207 (408).

  When the control unit 201 displays a message indicating that there is a call on the display unit 207, the control unit 201 stops the first communication unit 202 when receiving necessary information without waiting for the user to respond. The process is started (417). Thereafter, the second communication unit 203 resumes data communication using the second communication system.

  When the predetermined time has elapsed, the control unit 201 again interrupts communication using the second communication system and starts the reception operation of the first communication system. Since the base station 101 retransmits the call (304-1) because the mobile station 100 does not respond to the previous call (304), the first communication unit 202 receives the call (304-1).

  In the determination (405), if the incoming flag indicating that there was a previous incoming call is TRUE, the same display as the previous time is displayed on the incoming call display 408 (501). Thus, even if incoming calls are received continuously from the base station 101 during a one-call, display can be performed without changing the number of incoming calls.

  On the other hand, after the call 304 is received as shown in FIG. 6 and the incoming call display 501 is displayed on the display unit 207, the first communication unit 202 is stopped for a predetermined period. Set to FALSE (403). In that case, the same incoming call display 501 as the previous time is displayed on the display unit 207. After that, when a predetermined time has elapsed and the first communication unit 202 operates, it is determined that an incoming call (601) is received (405), and the incoming flag is set to FALSE. Add one incoming call (407). The incoming call display on the display unit 207 is displayed by adding one incoming call to the previously displayed number as shown at 602 (408).

  As described above, when the calls received by the first communication unit 202 are continuous, it is a call from the same caller, and when it is interrupted, it is determined that the call is a new call, thereby accurately determining the number of incoming calls. Can be displayed.

  In an existing communication system such as the CDMA system, caller information such as a telephone number is not included in the call 304, and after performing connection processing between the wireless communication terminal and the base station, the base station transmits the wireless communication terminal. To be sent to. As described above, in the present embodiment, the number of incoming calls is determined using an incoming flag that indicates whether or not the call 304 is continuous without using the information of the caller. For this reason, even when an existing communication system is used for the first communication system, it is not necessary to perform connection processing with the base station of the first communication system, so that data communication using the second communication system is immediately performed. The number of incoming calls in the first communication system can be notified to the user.

  After communication by the second communication system is completed, caller information is collectively received from the base station of the first communication system, and a telephone number or a name corresponding to the telephone number is displayed on the display unit 207. May be. According to this, it is possible to notify the user of the information of the other party who has received an incoming call while reducing the communication interruption time in the second communication system.

  In addition, as described below with reference to FIG. 7, connection processing may be performed with the base station, and it may be determined whether or not to accept an incoming call after receiving caller information. In this embodiment, since connection processing is performed with the base station, it takes more time to resume the second communication than in the embodiment shown in FIG. 4, but more information can be notified to the user. . By enabling the user to select the process shown in FIG. 4 and the process shown in FIG. 7 according to the use situation, the user-friendliness can be improved.

  Hereinafter, the flow of FIG. 7 will be described. 7, the same reference numerals as those in FIGS. 3 and 4 denote the same functions. When a call is received from the base station 103, connection processing is performed (409), and caller information reception processing is performed (410). Whether or not to accept an incoming call is determined (404), and if the user is set not to accept an incoming call, the received caller information and the number of incoming calls are clearly indicated on the display unit 207 (701). The content displayed on the display unit 207 may be the caller's telephone number, the name of the caller linked to the address book stored in the storage unit 206, or a photograph.

  When the reception of necessary information is completed, the first communication unit 202 starts a process of stopping (417), and then resumes high-speed data communication using the second system. The processing when the user is set to accept incoming calls is the same as the processing after ringing described with reference to FIG.

  FIG. 8 shows an embodiment of a display indicating that a call has occurred in the first communication system. Reference numeral 801 denotes a display indicating that high-speed data communication is being performed and contents received by a service using high-speed data communication. Reference numeral 802 indicates in characters that the first system has been called. Reference numeral 802 denotes a call of the first system, which displays caller information from the incoming call information, and further displays the number of incoming calls from the caller. An icon 803 indicates that the first system has been called. Further, an LED or the like provided in the wireless communication terminal 100 may be turned on without displaying on the display unit 207 that there has been a call.

  In the above embodiment, the case where a call in the first communication system is received when communication is performed in the second communication system has been described as an example, but the same applies to the opposite case. However, during communication in the first communication system, the user may be able to select a setting for stopping the second communication unit 203 all the time. For example, when the second communication system mainly performs data-dedicated communication or data communication, for example, wireless LAN or EV-DO (Evolution Data Only), the user omits the incoming call notification, There is a case where it is desired to receive data collectively after the end of communication in one communication system. Therefore, user convenience can be improved by making it possible to select a setting according to the use situation.

  In the above embodiment, when one of a plurality of communication systems is used, whether or not to accept a call to another communication system is set in the wireless communication terminal, but is limited to this. It may be registered in advance whether or not to accept the call to the base station. In this case, if the setting is such that the call is not accepted, the base station notifies the incoming call only once for one call regardless of whether there is a response from the terminal. In addition, when the user registers a time zone in which the call is not accepted, the base station can perform communication efficiently by collectively performing an incoming call notification after the time zone has elapsed.
