Description

  The present invention relates to a mobile communication terminal apparatus, and more particularly to a mobile communication terminal apparatus of a mobile communication system in which a plurality of mobile communication terminal apparatuses communicate via a base station.

  In recent years, with the widespread use of mobile phones and PHS, ringtones suddenly generated at places where people gather such as trains and movie theaters have become a problem. Conventionally, as a method of not ringing a ring tone according to the situation where the user is present, switching to the manner mode by the user manually is generally used.

  However, this method relies solely on user manners (morals, morals), and there are still many people who are not conscious of the inconvenience of others. In addition, even if there is no malicious intention, it may be forgotten to switch to the manner mode, so that the manner problem is more difficult to solve.

In this regard, conventionally, an automatic manner mode switching system (Patent Document 1) that detects that a mobile terminal is moving at high speed by a train or the like and automatically switches to the manner mode, or detecting background noise in the surroundings. A short-distance range in which a communication function of a mobile phone terminal approaching the facility is mounted on the terminal by a ringtone control method (Patent Document 2) for changing the volume and quality of the ringtone or a small power signal transmitted from a specific facility Techniques such as a portable communication suppression system (Patent Document 3) that suppresses via a wireless communication unit are known.

In the figure, 10 is a base station BS1, Z1 is a radio zone managed by the base station 10, 30 is a mobile communication terminal (hereinafter also referred to as a mobile station) MS1 to MS4, and A1 is a short-range radio wave from the mobile station MS1. This is an area (short range). In the example of FIG. 1, the mobile stations MS1, MS2, and MS4 are located in the radio zone Z1 that the base station BS1 has jurisdiction over, and the mobile station MS3 is located outside the radio zone Z1. In addition, the mobile stations MS2 and MS3 are located within the short-range coverage area A1 of the mobile station MS1. In the following description, it is assumed that each mobile terminal is arranged as shown.

  Note that the concept of the short-range area in the present embodiment includes a short-range area with a radius of 10 m or less to a middle-range area with a radius of 50 m or less. The short-range specification is suitable for applications where people are concentrated in a relatively small area such as a train or a restaurant. On the other hand, the specifications for the middle range are suitable for applications that cover a relatively wide area such as a library, a theater, and a museum.

  FIG. 2 is a block diagram of a mobile communication terminal apparatus according to the embodiment, and shows an application example to a mobile communication terminal apparatus (also referred to as a portable terminal) based on the CDMA system of the present invention. In the figure, 31 is an antenna for connecting to the base station 10, 32 is a transmission / reception demultiplexing switch, 33 is a radio receiver using CDMA, 34 is a despread demodulator for received data RD, and 36 is spread modulation for transmission data TD. , 37 is a CDMA wireless transmission unit, 38 is a frequency synthesizer, 41 is a synchronization control unit that controls the exchange of call control signals and voice and text data with the base station 10, and 42 is a voice transmission / reception unit. A codec (CODEC) that performs signal code conversion, 43 is a baseband processing unit that processes an audio band signal, 44 is a speaker (SPK), and 45 is a microphone (MIC).

Reference numeral 51 denotes a CPU that performs main control and call processing of the portable terminal, 52 denotes a memory (MEM) including a RAM, a ROM, an EEPROM, and the like that store programs executed by the CPU 51, operation data, and the like. A console (CSL) provided on the front side, 54 is a display unit (DSP) using liquid crystal, 55 is a keyboard (KBD) having dial keys, manner keys, and other various function keys, and 56 is a common bus for the CPU 51. .

  Furthermore, in addition to the configuration as a mobile station connected to the mobile communication system, the mobile terminal 30 includes a short-range wireless unit 60 for performing wireless communication directly between mobile terminals in a short-range area according to the present invention. I have. 61 is an antenna for short-range wireless communication, 62 is a transmission / reception demultiplexing switch such as a circulator, 63 is a wireless receiver capable of amplifying a received RF signal and detecting received electrolytic strength (RSSI), and 64 is a reception data RD. A demodulating unit, 65 is a modulation unit for transmission data TD, 66 is a wireless transmission unit, and 67 is a communication control unit that controls communication between a plurality of terminals.

  The short-range wireless unit 60 as an example can be realized as a medium-range communication unit using a known Bluetooth technology or a short-range communication unit using an RF (Radio Frequency) ID tag technology. Short-range communication is performed using radio signals of the same frequency for both uplink and downlink. The communication control unit 67 employs, for example, a well-known CSMA / CD (Carrier Sense Multiple Access with Collision Detection) method in order to smoothly (without collision) direct communication between an unspecified number of portable terminals. According to this method, the transmission side terminal starts transmission of a burst frame after confirming the absence of a reception carrier. Also, during frame transmission, the radio reception unit 63 receives and demodulates the received radio waves, and compares the transmission and reception contents momentarily to detect the presence or absence of a collision, or observe the received RSSI during data transmission A method of detecting a collision by exceeding a predetermined threshold can be adopted. If a collision is detected during frame transmission, the transmission is immediately stopped and a burst frame is transmitted again after a random time delay. On the other hand, the receiving side terminal captures only frames that have been successfully received, and discards frames that have received errors.

  In the nonvolatile storage area of the memory 52, a storage area for incoming mode information is provided. As an incoming mode of the mobile terminal, there are a manner mode in which an incoming call is notified by vibration and a normal mode in which a sound (buzzer, melody, etc.) is notified. The incoming call mode is set to the default normal mode when the terminal is shipped. After that, when the user presses the manner key (not shown), the mode is switched to the manner mode, and when the user presses the manner key again, the mode is changed to the normal mode. . The mobile terminal that has received an inquiry about the incoming mode reads out the incoming mode in the memory 52 and responds to the inquiry source, so that the aggregate value can reflect the manner level (good sense) of each user in the short-distance range.

  When an incoming call is received, the user is basically notified of the incoming call in accordance with the incoming call mode of the memory 53, but in actuality, the current incoming call mode is determined according to the communication environment using the short-range wireless unit 60, and the incoming call is received. Notify incoming calls according to mode. However, the contents of the memory 52 are not rewritten in the current incoming mode.

  FIG. 3 is a sequence diagram of the incoming call processing according to the embodiment, and shows an application example to the mobile communication system of FIG. When the mobile station MS1 is powered on, the CPU 51 connects to the nearest (best communication quality) base station (perch channel) BS1, receives the designation of its own standby channel from the base station BS1, and enters a standby state. The same applies to the other mobile stations MS2 and MS4. Note that the mobile station MS3 in this example is connected to another base station (not shown). In this state, when there is an incoming call from the base station BS1 to the mobile station MS1, the mobile station MS1 that has received the call starts an incoming call mode inquiry process using the short-range wireless unit 60 in step S51.

In the short-range wireless unit 60 that has received this, the communication control unit 67 confirms in step S61 that there is no carrier (that is, the RSSI is equal to or lower than a predetermined value), and then simultaneously transmits an inquiry frame for the incoming mode ( Broadcast), and in step S62, a timer for a predetermined time (within 1 second) is started.

 This inquiry frame includes the terminal number of the MS 1 that is the transmission source, information indicating an incoming mode inquiry, and the like. The terminal number (mobile device number) is preferably a unique number for each terminal as determined according to the manufacturer, production lot, and the like. Therefore, even if terminals of various manufacturers are mixed within a short range, the difference between the terminals can be easily identified. The subscriber number (telephone number) is not used here because it is not desired to be known to unspecified persons.

  The mobile station MS2 in the near field A1 forms the response frame by receiving the inquiry frame normally, and confirms that there is no reception carrier after waiting for a random time in step S71. Return 2 This response frame includes the terminal number of the mobile station MS2 that is the transmission source, the reception mode of the local station read from the memory 52, the terminal number of the mobile station MS1 that is the inquiry source of the reception mode, and the like. Similarly, the mobile station MS3 in the short-range area A1 also responds with its own incoming mode after a random time delay in step S72. On the other hand, since the inquiry frame does not reach the mobile station MS4 outside the short range, no response frame is transmitted.

  Thus, if the timer eventually times out, the received contents are totaled in step S63. The total number of incoming responses is calculated in consideration of the inquiry source terminal number and the response source terminal number. An incoming response frame with a different inquiry source terminal number is discarded. If the response terminal number is duplicated, one is discarded. In step S64, a reception mode determination process described later is executed to determine the current incoming mode, and the process returns to this process. In step S66, the CPU 51 determines whether or not the current incoming mode is the manner mode. If the mode is the manner mode, the user is called in the manner mode in step S67. On the other hand, if it is not the manner mode, the normal mode is called in step S68.

  4 and 5 are flowcharts (1) and (2) of the incoming mode determination processing according to the embodiment, and FIG. 4 (A) shows the incoming mode of the own station according to the number of incoming responses from each terminal within a short range. Shows when to do. In step S11, it is determined whether or not the number of incoming responses exceeds a predetermined threshold value α (for example, 5 to 10). If so, the current incoming mode is determined to be the manner mode in step S12. If not, the current incoming mode is determined to be the normal mode in step S13.

  According to the present embodiment, for example, in a train or a bus, the manner mode is determined when there are many passengers, and the normal mode is determined when there are few passengers.

  FIG. 4B shows a case where the incoming mode of the own station is determined in accordance with the incoming mode in which each terminal within a short range is set. In step S21, the manner ratio is obtained by (number of manners) / (number of incoming responses). In step S22, it is determined whether or not the manner ratio exceeds a predetermined threshold β (for example, 0.5), and if it exceeds, the current incoming mode is determined to be the manner mode in step S23. If not, in step S24, the current incoming mode is determined to be the normal mode.

  According to the present embodiment, for example, since the manner ratio is low in a lobby of a movie theater, the normal mode is determined. However, since the manner ratio is high in a spectator seat during a movie, the manner mode is determined.

FIG. 5A shows a case where the present incoming mode is determined to be the manner mode due to the high manner ratio even if the number of incoming responses is small. In step S31, it is determined whether or not the number of incoming responses exceeds a predetermined threshold value α. If it exceeds, the current incoming mode is determined to be the manner mode in step S35. If it is determined in step S31 that the number of incoming responses does not exceed the predetermined threshold value α, the manner ratio is obtained from (number of manners) / (number of incoming responses) in step S32. In step S33, it is determined whether or not the manner ratio exceeds a predetermined threshold value γ (for example, 0.5). If it exceeds, the current incoming mode is determined to be the manner mode in step S35. If not, the current incoming mode is determined to be the normal mode in step S34.

  In the present embodiment, for example, even if there are sparse people appreciating artwork on the floor of an art museum, since most of these people are set to the manner mode, the manner ratio becomes high, and thus the manner mode is set. To be determined.

  FIG. 5B shows a case where the current incoming mode is determined as the normal mode based on the fact that the manner ratio is small even if the number of incoming responses is large. In step S41, it is determined whether or not the number of incoming responses exceeds a predetermined threshold value α. If not, in step S43, the current incoming mode is determined as the normal mode. On the other hand, if the number of incoming responses exceeds the predetermined threshold value α in step S41, the manner ratio is obtained by (number of manners) / (number of incoming responses) in step S43. In step S44, it is determined whether the manner ratio is below a predetermined threshold δ (for example, 0.3). If it is below, the current incoming mode is determined to be the normal mode in step S43. On the other hand, if not lower, the current incoming mode is determined to be the manner mode in step S45.

  According to the present embodiment, for example, even in a crowd of people in the city, since most of these people are set to the normal mode, the manner ratio is reduced, so that the normal mode is determined.

  In the above embodiment, the mobile station MS1 transmits the inquiry frame for the incoming mode in the near field A1, but the present invention is not limited to this. Even when a predetermined (known) frame common to the system is transmitted within the short-range area A1, each of the surrounding mobile stations MS2 and MS3 can return a predetermined response frame by receiving the known frame. The manner mode can be determined based on information obtained by counting the number of incoming responses.

  Moreover, although the case where the manner mode and the normal mode exist has been described in the above embodiment, the present invention is not limited to this. For example, a mode corresponding to the manner mode may be handled as the manner mode, and other modes may be handled as the normal mode. Therefore, the present invention can be applied to portable terminals of various manufacturers.

  Moreover, although several embodiment suitable for the said invention was described, it cannot be overemphasized that the structure of each part, control, a process, and these combination can be variously changed within the range which does not deviate from this invention. .
