[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a system configuration diagram of an embodiment of a wireless communication system according to the present invention. In FIG. 1, a mobile terminal 101 is a terminal that always listens for an incoming call, such as a mobile phone, and includes a wireless device 100 that can switch between an ad hoc mode and a public mode, a speaker and a vibration function 111, and generates an incoming call. Sometimes, the user can be notified, and the mobile terminal itself has a voice call function. Further, the host terminals 102 and 103 are a notebook personal computer, a PDA (portable information device), or the like, include the wireless device 100, and have a voice-only function or a telephone call function such as a videophone. The wireless communication system according to the present embodiment assumes a case where the same user owns and operates the portable terminal 101 and one or more host terminals 102 and 103 arbitrarily.
[0020]
The portable terminal 101 and the host terminals 102 and 103 implement a wireless LAN according to the recommendation 802.11b defined by the IEEE as the wireless device 100. This wireless LAN uses a frequency of the 2.4 GHz band, the modulation method is a direct spread (DS) method, and the transmission speed is 11 Mbps or 5.5 Mbps. Then, in the public mode 108, the wireless LAN device can talk with the host terminal 106 of the other party connected to the Internet 105 via the wireless base station 104. When the wireless device is in the ad hoc mode 109, communication can be performed between the portable terminal 101 and the host terminals 102 and 103. When the wireless device is a wireless LAN, the public mode is generally called an infrastructure mode, and the wireless base station 104 is called a wireless LAN access point.
[0021]
In order to establish a call between the calling side and the called side, a SIP (Session Initiation Protocol) recommended by the Internet Engineering Task Force (IETF), which is an Internet standardization organization, and an RTP for transferring voice and image data. (Real-time Transport Protocol) and H.264 recommended by ITU-T (International Telecommunication Union Telecommunication Standardization Sector). For example, a protocol such as H.323 is used. In addition, usually, for establishing a voice call, a dedicated call control server 107 is installed to ensure mobility of a mobile terminal and a host terminal across a network site, and to identify a partner such as a telephone number. Perform association with the user terminal.
[0022]
The outline of this wireless communication system will be described. While waiting for an incoming call from the host terminal 106 of the other party, the host terminals 102 and 103 turn off the power of the wireless device and wait for the incoming call only at the portable terminal 101. Then, when an incoming call occurs in the portable terminal 101, the operation mode of the wireless device is switched from the public mode 108 to the ad hoc mode 109, and a ring tone is sounded to inform the user. At this time, the user who has noticed the occurrence of the ringing tone responds to the incoming call (off-hook) by pressing the call button of the host terminal 102 or 103 that the user actually wants to use for the call. Of course, when a call is to be made with the mobile terminal 101, the call button of the mobile terminal 101 may be pressed.
[0023]
In the host terminal 102 or 103 on which the call button is pressed, the wireless device power control unit 110 turns on the power of the wireless device and sets the wireless device in the ad hoc mode 109, and then requests the mobile terminal 101 for the network setting information 112. The portable terminal 101 reads out the codec capability of the host terminal 102 or 103 that has requested the network setting information 112 from the profile storage unit 113 and compares it with the codec capability of the partner host terminal 106 included in the incoming call signal to enable a call. In this case, the network setting information 112 is transmitted to the host terminal 102 or 103 for which the call button has been pressed. The host terminal 102 or 103 that has received the network setting information 112 sets the public mode 108 using the network setting information 112, transmits an incoming call response to the partner host terminal 106, and starts talking.
[0024]
Next, the configuration of the mobile terminal 101 will be described. FIG. 4 is a functional block diagram of the mobile terminal 101 according to an embodiment. In the figure, a wireless control unit 401 switches to a public mode or an ad hoc mode in accordance with an instruction from a wireless mode switching unit 402, and transmits data received from a radio wave to a network setting information request receiving unit 403 and a call application 404. Alternatively, data input from the network setting information transmitting unit 405 or the call application 404 is converted into a predetermined transmission signal form and transmitted by radio waves.
[0025]
The network setting information request receiving unit 403 detects the reception of the network setting information request and supplies it to the call determining unit 406. The call determination unit 406 compares the codec capability included in the incoming signal notified from the call application 404 with the codec capability stored in the profile storage unit 407, and compares the determination result with the network setting information transmission unit 405 and the call Notify the application 404.
[0026]
The network setting information transmitting unit 405 reads the currently set network setting information from the network setting information storage unit 408 and supplies it to the wireless control unit 401 when the determination result from the call determining unit 406 is successful (call is possible). In the case of rejection (call cannot be made), rejection of the network setting information is supplied to the wireless control means 401. The wireless mode switching unit 402 reads the network setting information from the network setting information storage unit 408 according to the instruction of the call application 404, and sets the network setting information in the wireless control unit 401.
[0027]
The call application 404 receives an off-hook or on-hook operation or a determination result from the call determination unit 406, starts a call with the partner host terminal 106, or instructs the wireless mode switching unit 402 to switch. The profile storage unit 407 stores the codec capability of the host terminal. The network setting information storage unit 408 stores one or more network setting information to which the mobile terminal 101 can be connected.
[0028]
FIG. 6 shows an example of the configuration of the network setting information stored in the network setting information storage means 408. Network setting information is classified into wireless base station information 601 and call control server information 602. The wireless base station information 601 includes an ESSID (Extended Service Set-IDentifier) 604 for grouping the wireless base stations, and a WEP key (Wired Effective Privacy Key) 605 for authentication. The wireless base station information 601 is the setting of the wireless LAN set in the mobile terminal when an incoming call occurs in the mobile terminal. The call control server information 602 includes a server IP address 606, a user ID 607 used for authentication, and a password 608.
[0029]
Next, the configuration of the host terminals 102 and 103 will be described. FIG. 5 shows a functional block diagram of an embodiment of the host terminal. In the figure, a wireless control unit 501 switches to a public mode or an ad hoc mode in accordance with an instruction from a wireless mode switching unit 502, and supplies data received from a radio wave to a network setting information receiving unit 503 and a call application 504, The data supplied from the network setting information request unit 505 or the call application 504 is converted into a transmission signal form and transmitted by radio waves.
[0030]
The wireless device power control unit 506 turns on or off the power of the wireless device according to an instruction from the call application 504. The wireless mode switching unit 502 instructs the wireless control unit 501 to switch to one of the public mode and the ad hoc mode according to an instruction from the network setting information receiving unit 503 or the communication application 504.
[0031]
The network setting information request unit 505 outputs a request for network setting information addressed to the mobile terminal to the wireless control unit 501 in accordance with an instruction from the call application 504. The network setting information receiving unit 503 supplies the network setting information input from the wireless control unit 501 to the wireless mode switching unit 502, and notifies the call application 504 of the reception result of the network setting information. The call application 504 establishes a call with the partner host terminal based on an off-hook or on-hook operation or a result of reception from the network setting information receiving unit 503, or instructs the wireless mode switching unit 502 to switch.
[0032]
Next, a table configuration stored in the profile storage unit 113 in FIG. 1 will be described. FIG. 7 shows an example of a table configuration of the profile storage means of the portable terminal. As shown in the figure, the table has a configuration in which a terminal ID 701 for identifying a host terminal or a portable terminal and a codec capability 702 indicating the capability of a codec of each terminal are stored in association with each other. In this embodiment, the terminal ID 701 is an arbitrary character string (MT, NOTEPC, PDA, etc.) for distinguishing each host terminal. The codec capability 702 includes “medium quality voice”, “videophone”, “high quality voice”, and the like.
[0033]
Next, the operation of the wireless communication system according to the present embodiment including the above devices and functional blocks will be described in detail with reference to the flowcharts of FIGS. Here, FIG. 2 is a flowchart illustrating the operation of the mobile terminal 101, and FIG. 3 is a flowchart illustrating the operation of the host terminals 102 and 103.
[0034]
First, assuming that the mobile terminal 101 detects the occurrence of an incoming call from the partner host terminal 106 (step 200 in FIG. 2), the wireless mode is switched to the ad hoc mode (step 201 in FIG. 2), and the timer is started (FIG. 2). In step 202 of FIG. 2, a melody is sounded to notify the user of the occurrence of an incoming call (step 203 in FIG. 2).
[0035]
Accordingly, when the user presses the call button of the host terminal 102 or 103 to perform an incoming call response (step 300 in FIG. 3), the wireless device power control unit 506 issues an instruction from the call application 504, and After the power is turned on (step 301 in FIG. 3) and the wireless mode switching unit 502 sets the operation mode of the wireless control unit 501 to the ad hoc mode (step 302 in FIG. 3), the mobile terminal 101 requests the network setting information. Is transmitted (step 303 in FIG. 3), and a timer is started (step 304 in FIG. 3). The request for network setting information includes a terminal ID for identifying a terminal that has transmitted the request for network setting information.
[0036]
When the mobile terminal 101 receives the request for network setting information transmitted from the host terminal 102 or 103 by the network setting information request receiving unit 403 (step 204 in FIG. 2), the call determining unit 406 causes the profile storage unit 407 (FIG. The codec capability is called from the table of 1) 113) using the terminal ID included in the request for the network setting information as a key, and the codec capability of the partner host terminal 106 included in the incoming signal notified from the call application 404 is compared. Then, it is determined whether communication is possible (step 205 in FIG. 2).
[0037]
For example, referring to the table of the profile storage unit 113 (407 in FIG. 4) shown in FIG. 7, if it is assumed that the terminal ID 701 of the host terminal 102 that has pressed the call button is “NOTEPC”, the codec capability 702 is If it is “videophone” (shown by 703 in FIG. 7) and the codec capability of the partner host terminal 106 included in the incoming signal is “videophone”, the two codecs match and the call is possible. , And notifies the network setting information transmitting unit 405 of the determination result as success.
[0038]
Thus, the network setting information transmitting unit 405 reads the currently set network setting information from the network setting information storage unit 408 and wirelessly transmits the network setting information via the wireless control unit 401 as indicated by 112 in FIG. 1 (FIG. 2). Step 206). Subsequently, the portable terminal 101 switches to the public mode by the wireless mode switching unit 402 (step 207 in FIG. 2), and stops the incoming melody (step 208 in FIG. 2).
[0039]
Here, the network setting information 112 transmitted by the mobile terminal 101 to the host terminal 102 that has requested the network setting information in step 206 in FIG. 2 includes the current network setting information stored in the network setting information storage unit 408 shown in FIG. Wireless base station information 601 and a call control server 602 are included.
[0040]
When the host terminal 102 detects network setting information from the received signal supplied via the wireless control unit 501 by the network setting information receiving unit 503 (YES in step 305 in FIG. 3), the wireless mode switching unit 502 performs wireless control. An instruction is given to switch the means 501 to the public mode (step 306 in FIG. 3). Subsequently, the host terminal 102 transmits an incoming call response (reconnection request) to the call control server 107 shown in FIG. 1 to start a call with the partner host terminal 106 (step 307 in FIG. 3).
[0041]
On the other hand, if it is determined in step 205 in FIG. 2 that the host terminal that has pressed the talk button is the host terminal 103 and its terminal ID 701 is “MT”, its codec capability 702 is “medium quality voice”. On the other hand, if the codec capability of the partner host terminal 106 included in the incoming signal is "videophone", the two codec capabilities do not match, so the call determination means 406 determines that the telephone cannot be communicated, and The determination result is notified to the network setting information transmitting unit 405 and the call application 404.
[0042]
Based on the notification of the rejection determination result, the network setting information transmitting unit 405 of the portable terminal 101 causes the wireless control unit 401 to wirelessly transmit the rejection of the network setting information to the host terminal 103 that has requested the network setting information (FIG. 2). Step 209). Subsequently, the portable terminal 101 switches to the public mode by the wireless mode switching means 402 (step 210 in FIG. 2), and stops the incoming melody (step 208 in FIG. 2).
[0043]
On the other hand, when the network setting information receiving unit 503 detects rejection of the network setting information from the received signal supplied via the wireless control unit 501 (YES in step 308 in FIG. 3), the host terminal 103 transmits the call application 504 to the host terminal 103. The power of the wireless device is turned off by controlling the wireless device power control unit 506 via the wireless device (step 309 in FIG. 3).
[0044]
In addition, when the host terminal 102 or 103 rejects the network setting information and the network setting information and does not receive both, and a timeout occurs (steps 305, 308, and 310 in FIG. 3), the power of the wireless device is also turned off ( Step 309 in FIG. 3).
[0045]
Further, when the operation of the incoming call response (off-hook) is performed not by the host terminal 102 or 103 but by the mobile phone 101, the setting information acquisition request is not received and the off-hook is detected (step 204 in FIG. 2). 211) At this time, the wireless control unit 501 switches from the ad hoc mode to the public mode based on the instruction of the off-hook call application 404 (step 212 in FIG. 2), and transmits an incoming response to the call control server 107 in FIG. 1 (step 212). In step 213 in FIG. 2, a call with the partner host terminal 106 is started.
[0046]
In the case where a timeout has occurred without performing either a request for network setting information from the host terminals 102 and 103 or an operation of an incoming call response (off-hook) on the mobile terminal 101 (steps 204, 211, 214 in FIG. 2), In accordance with the instruction from the call application 504, the wireless control unit 501 switches from the ad hoc mode to the public mode (step 215 in FIG. 2). In addition, the partner host terminal 106 continues to sound a ringing sound, which is generally called ringing, from when the mobile terminal 101 and the host terminals 102 and 103 are called until a call is established.
[0047]
As described above, according to the present embodiment, incoming call waiting for portable terminal 101 and host terminals 102 and 103 is performed by one portable terminal 101, so that host terminals 102 and 103 that do not perform incoming call waiting are used. Power saving can be realized. In addition, by executing the standby for incoming calls to the host terminal 103 having different codec capabilities with one portable terminal 101, power saving of the terminal 102 that does not perform standby for incoming calls can be realized.
[0048]
Further, in this embodiment, the host terminals 102 and 103 acquire network setting information from the mobile terminal 101, so that the host terminal 102 or 103 that makes a call does not newly detect a network. Power saving can be realized by suppressing unnecessary radio wave transmission.
[0049]
Further, in this embodiment, even if there is an incoming call to the host terminals 102 and 103 that do not have a vibration mode or the like as an incoming call notifying method to the user, it is possible to use the incoming call notifying method implemented in the mobile phone. it can.
[0050]
Note that the present invention is not limited to the above embodiment. For example, in FIG. 1, two host terminals 102 and 103 are used, but any number of host terminals may be used as long as the number is one or more. In FIG. 1, only the power of the wireless device is turned on / off, but the power of the entire terminal may be turned on / off. Further, the storage table of the profile storage unit 113 (407) in FIG. 7 describes one codec capability for one terminal ID, but describes many codec capabilities for one terminal ID. Is also good.
