DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a mobile communication terminal according to the present invention will be described in detail below with reference to the accompanying drawings.
[0023]
FIG. 1 is a diagram showing an example of the configuration of a mobile communication terminal according to the present invention.
[0024]
In FIG. 1, the mobile communication terminal 1 includes a control unit 11, a wireless telephone communication unit 12, a short-range wireless communication unit 13, a communication start request generation unit 14, an application activation unit 15, and a memory 16.
[0025]
The control unit 11 controls each unit to control and control various communication functions and data processing functions of the mobile communication terminal 1. The wireless telephone communication unit 12 performs input / output transmission processing of information by wireless communication via a wireless base station, and realizes voice calls and mail transmission / reception via a general communication network such as a telephone network or the Internet. The distance wireless communication unit 13 performs input / output transmission processing of information by short-range wireless communication based on the control signal of the control unit 11, and realizes direct communication between terminals not via a general communication network.
[0026]
Prior to executing the short-range wireless communication, the communication start request generation unit 14 generates a communication start request for requesting the counterpart terminal to start communication using the short-range wireless communication unit 13.
[0027]
The memory 16 stores various applications implemented by the mobile communication terminal 1, and the application activation unit 15 activates various applications stored in the memory 16 based on a control signal from the control unit 11.
[0028]
In this embodiment, a case where a Bluetooth transmission / reception device is used for the short-range wireless communication unit 13 will be described as an example.
[0029]
Here, Bluetooth is a short-range wireless voice / data communication standard of point-to-point or point-to-multi-point using weak radio waves (2.4 GHz band frequency), Spread spectrum communication is performed to avoid interference between multiple devices. There are three classes of the maximum communication distance depending on the transmission output, but it is about 10 m to 100 m. Bluetooth has been developed based on a small wireless transceiver, which is assigned a 48-bit unique address that conforms to the IEEE 802 standard. Binary FM modulation is used for communication to realize time-division full-duplex communication.
[0030]
In order to perform such short-range wireless communication using Bluetooth, first, it is necessary to activate the Bluetooth communication functions of the terminals that are to communicate, and to establish a session by recognizing each other.
[0031]
FIG. 2 is a flowchart for explaining processing for establishing communication by the Bluetooth communication function between the terminals shown in FIG.
[0032]
A terminal requesting Bluetooth communication (hereinafter referred to as an initiator terminal) activates the Bluetooth communication function by activating the short-range wireless communication unit 13 based on a user operation (step 101) and desires communication. A communication start request by Bluetooth communication is transmitted to the counterpart terminal (hereinafter referred to as an acceptor terminal) by the wireless telephone communication unit 12 via a general communication network (step 102). Note that the timing of starting the short-range wireless communication unit 13 of the initiator terminal is not limited to this, and may be after the communication start request is transmitted.
[0033]
When the acceptor terminal receives the communication start request from the initiator terminal in the wireless telephone communication unit 12, the acceptor terminal determines whether or not to agree with the communication start request (step 103), and when agreeing (YES in step 103). Then, the short-range wireless communication unit 13 is activated to activate the Bluetooth function (step 104). The consent determination process for determining whether or not to agree with the communication start request will be described in detail later.
[0034]
Subsequently, the acceptor terminal transmits a Bluetooth connection request to the initiator terminal via the short-range wireless communication unit 13 (step 105), and when the initiator terminal responds to the Bluetooth connection request (step 106), between the two terminals Then, a Bluetooth connection session is established (step 107). The initiator terminal may issue the Bluetooth connection request.
[0035]
As described above, after the Bluetooth connection session is established between the two terminals, the initiator terminal and the acceptor terminal each start a predetermined communication application (108), thereby the communication application using the Bluetooth communication function between the two terminals. Can be used (step 109).
[0036]
The consent determination process (step 103) for the communication start request in the acceptor terminal is automatically performed on the terminal side based on the state of the acceptor terminal itself or information on the initiator terminal sent together with the communication start request, or user operation Based on. Here, the information related to the initiator terminal includes the telephone number and mail address of the initiator terminal, identification information of the Bluetooth communication function provided in the initiator terminal, and the like.
[0037]
When determining whether or not to respond to the communication start request based on the user operation, the acceptor terminal first displays information on the initiator terminal received together with the communication start request on the display unit (not shown) to the user. Present. Based on the presented identification information and the current usage status of the acceptor terminal, etc., the user inputs whether or not to agree to this communication start request from a key input unit (not shown) of the acceptor terminal, thereby accepting the acceptor. The terminal determines whether to activate the Bluetooth communication function.
[0038]
Next, the case where it is determined whether or not the terminal side automatically responds to the communication start request will be described.
[0039]
FIG. 3 is a diagram showing another example of the configuration of the mobile communication terminal according to the present invention, in which the same parts as those in FIG. 1 are denoted by the same reference numerals.
[0040]
In FIG. 3, the mobile communication terminal 1 further includes a Bluetooth connection condition setting unit 17 in which a criterion for determining whether or not to respond to a communication start request from the initiator terminal is set.
[0041]
The Bluetooth connection condition setting unit 17 is set with conditions for determining whether to respond to a communication start request. This condition is, for example,
(1) Identification information of initiator terminal (2) Acceptance status of acceptor terminal (3) Time (4) Set according to items such as communication application to be used, and the Bluetooth connection condition setting unit 17 sets each of these items. Whether or not to respond to the communication start request is defined correspondingly or corresponding to a combination of a plurality of items.
[0042]
When the acceptor terminal receives the communication start request, the acceptor terminal analyzes the received communication start request and the state of itself and refers to the Bluetooth connection condition setting unit 17 to determine whether to respond to the communication start request.
[0043]
Whether the terminal performs the above-described consent determination process based on a user operation or automatically based on a predetermined condition is, for example, for a terminal that has never established a connection in the past Based on the user operation, it is preferable to switch according to conditions such as automatically establishing a connection to a terminal that has established a connection once.
[0044]
【The invention's effect】
As described above, according to the present invention, the initiator terminal transmits a communication start request to the acceptor terminal that desires communication via the first communication means such as the telephone network or the Internet . since establishing a connection session using the second communication means between the two terminals in response to a communication start request from a terminal, there is an effect that obtain easily rows activation of the communication application using the second communication means.
