[0001]
　The disclosure herein relates to wireless communication systems, methods and apparatus for messaging by particular wireless terminal.
Background technique
[0002]
　Since the high-performance wireless terminals such as smart phones and tablet computers have spread, and also spread more broadband wireless communication services, such as Long term Evolution (LTE) and public wireless local area network (WLAN), instant in the wireless terminal messaging (IM) services have become so is widely used (for example, see Patent documents 1 and 2). IM provides a text-based communication real-time to a plurality of users utilizing the same IM application. A plurality of wireless terminals plurality of users use performs the same IM application. IM is, mobile messaging (mobile messaging), text chat (text chat), it may also be referred to as a text-based messaging (text-based messaging), or interactive messaging (interactive messaging).
[0003]
　In this specification, regardless of whether or not specific to IM, the application that provides text or text-based messaging between the plurality of online users utilizing the same application is defined as IM application. Representative examples of IM applications, LINE, WhatsApp, Text Me!, Viber, Kakao Talk, Skype, a Google Hangouts, iMessage, Twitter, and Facebook and the like. It should be noted that the names of these IM applications is a trademark or registered trademark of operators each of the IM service.
[0004]
　IM is provided via the IM server system managed by the operator of the IM service. That is, the wireless terminal of the first user using the IM application sends a second user message addressed to the IM server system. Then, IM server system transmits the second user a message addressed to the wireless terminal of the second user using the same IM application.
[0005]
　In addition, some IM services, provides a different special account with normal user account to be paid out to the normal user (typically referred to as account). Special account has the authority to simultaneously delivered a message to a large number of account addressed as compared to the normal account. For example, the special account, use government offices, companies, commercial facilities, publishers, and is issued such as broadcasting stations, public services, goods, commercial services, magazines, in order to widely transmitted to a large number of user information about TV programs It is.
[0006]
　Sending a message to the sender a special account (called a special message), for example, it can be carried out in a Web-based operations. Specifically, the user of the special account, access to the IM server system (Web server) using a Web browser, to send a special message from Web-based management screen.
[0007]
　Moreover, it is also provided a mechanism for transmitting a special message from a wireless terminal normally account is set. Specifically, the user of a special account, normally account that is used to transmit a special message, and registers the IM server system. As an example, IM server system may provide a bot account for posting the special message for each special account. In this case, the user of a special account registers the bot account for special messages posted to the account list usually accounts (commonly called friends or buddies), the normally bot account account list (friends or buddies) to request the bot account to register an account. bot account, upon registering a normal account, to request the input of the password. This password is issued to the user of a special account by the operator of the IM service, for example, can be obtained from the special account Web-based management screen. When the normal registration accounts to bot account account list (friends Friends or buddies) is successful, the user of a special account, may transmit a message from a normal account registered to the bot account addressed. IM server system, a message that has been received by the bot account from the normal accounts that are registered, to send as a special message to the recipients of the special account.

Summary of the Invention
Problems that the Invention is to Solve
[0009]
　The present inventors have studied the system for disasters such as major earthquakes is available the communication of IM applications even when that occurred. When disaster such as earthquake occurs, there is a risk of equipment stops or IM server system itself stops, such as cellular networks and a public WLAN, thereby wireless terminal is inaccessible afraid IM server system. Accordingly, the present inventors have found that a plurality of radio terminals by using such WLAN communication function or Bluetooth (registered trademark) communication function with the wireless terminal (smart phone, etc.) to form a self-supporting manner wireless multi-hop network, the and consider making the communication of IM applications on a wireless multi-hop network.
[0010]
　Here, the wireless multi-hop network, mobile ad-hoc network (MANET) or disruption tolerant network (DTN), or a combination thereof. Disruption tolerant network may also be referred to as a delay tolerant network or disconnect tolerant network. In this specification, referred to as DTN are collectively Disruption / delay / disconnect tolerant network. MANET is generally assumes that the communication path between the source node and the destination node exists. Specific examples of the MANET is, ZigBee, ZigBee PRO, ZigBee IP, and ad-hoc mode of WLAN (IEEE 802.11), and the like. In contrast, DTN is based on the assumption that temporary or intermittent communication interruption occurs. In other words, DTN, at the time when at least some, it is assumed that stable communication path between the source node and the destination node does not exist. To address the temporary or intermittent communication interruption, the DTN node performs a store-and-forward operation. Therefore, DTN can also be referred to as a store-and-forward type of wireless multi-hop network.
[0011]
　IM applications of the wireless terminal, for example, receives a message via the wireless multi-hop networks, against the account list (friends Friends or buddies) that is stored the source account ID of the message to the radio terminal, transmission source message display for the user if the account ID is included in the account list, a message must be included may be hidden. Normal message transmission account not through the IM server system, it can be realized by this mechanism.
[0012]
　However, it is not easy to send a special message to the sender a special account without using the IM server system from the wireless terminal. Because the special account is not directly associated with the wireless terminal IM application, the transmission of the special message is to require access to an IM server system. That is, as described above, the transmission of special messages, access the IM server system (Web server), it can be carried out from the Web-based interface. The transmission of the special message can be done by sending a message to the bot account provided by the IM server system. However, it is not special account is merely usually account for is set to installed IM applications to the wireless terminal. Therefore, at the time of the wireless multi-hop operation in the event of a disaster, it is not possible to send a special message to the sender a special account from the wireless terminal. For example, government officials, might want to provide information to the widely citizens using a special account of the Government. However, government officials, to be able to access to the IM server system of the IM service operator, it is not possible to use the special account.
[0013]
　Incidentally, the above-mentioned problems can also occur in other communication services is not limited to messaging service (IM service) (e.g., online services such as various social networking service (SNS)). Other different communication services and IM services (e.g., SNS) also in generally accounts and special accounts may be distinguished. Usually account is a normal user account to be paid out to the normal user. On the other hand, special account refers to the account that has been given different rights from the usual account by the operator of communication services. For example, special accounts, corporation or individual to provide a highly specially certified public information by the operator of communication services (for example, government agencies, government agencies, companies, broadcasting stations) may be an account of. Also, special account, may have the right to publish information widely to the public than normal accounts, typically may have the right to communicate with a large number of accounts in comparison to the account, the normal account it may be authorized to provide wide information to a large number of accounts than, or have the authority can collect information from a large number of accounts than normal account.
[0014]
　Also in different other communication services to the IM service, it may be necessary to access to the communication service server in order to take advantage of the special account. In this case, for example if Kere Nare can access the communication service server in the event of a disaster, it is not possible to use the special account. For example, government officials, might want to provide information to the widely citizens using a special account of the Government. However, government officials, to be able to access the communication service server, it is not possible to use the special account.
[0015]
　Therefore, one of the objective to be achieved is the embodiment disclosed herein, the communication service server (e.g., IM server or SNS server) at the time of abnormality can not access, installed communication service applications to a wireless terminal (e.g., IM application or SNS application) is to provide a wireless terminal, method, and program that helps to perform the communication by special account with. Other objects or problems and novel features will become apparent from the description, or the accompanying drawings of this specification.

Specific examples of a device that receives an input operation by the user's hand, including a keyboard, a keypad, a touch panel, a touch pad, and a mouse.
[0036]
　Then hereinafter, detailed description will be given of the operation of the wireless terminal 10 and IM client. As already mentioned, the wireless terminal 10 operates as an IM client by executing an IM application 122. In other words, the radio terminal 10, via the IM server system 50 of the messaging service operator sends a message whose transmission source is normal account user receives a message that the normal accounts addressed. Normal account user through the operation of the input device 113 by the user, is set to the IM application.
[0037]
　Wireless terminal 10 and IM client may further send a special message to the sender a special account via the IM server system 50. As already mentioned, the special account, has the authority to simultaneously delivered a message to a large number of account addressed as compared to the normal account. For example, the special account, use government offices, companies, commercial facilities, publishers, and is issued such as broadcasting stations, public services, goods, commercial services, magazines, in order to widely transmitted to a large number of user information about TV programs It is.
[0038]
　A specific example of a transmission of messages to sender special account (called a special message) will be described with reference to FIG. In step S11, the user is normally accounts that are used for transmission of the special message, and registers the IM server system 50. As an example, IM server system 50 may provide a bot account for posting the special message for each special account. In this case, the user registers the bot account for special messages posted to the account list usually accounts (commonly referred to as friends or buddies), registers the ordinary account to bot account account list (friends or buddies) to request the bot account to. bot account, upon registering a normal account, to request the input of the password. This password is issued to the user of a special account by the operator of the IM service, for example, can be obtained from the special account Web-based management screen. When bot ordinary account registration account to the account list (friends Friends or buddies) to be successful, the user will be able to send a special message from the radio terminal 10.
[0039]
　In step S12, the user, by operating the wireless terminal 10 sends a message to the bot account destined usually account registered. IM server system 50, a message received by the bot account normal account registered, and transmits a special message to the recipients of the special account.
[0040]
　Alternatively, the transmission of messages to sender special account (called a special message), for example, may be carried out in a Web-based operations. Specifically, the user accesses the IM server system (Web server) using a Web browser application of the wireless terminal 10 may transmit a special message from the Web-based interface.
[0041]
　Further, the wireless terminal 10 and IM client, even abnormality can not access the IM server system 50, using IM application 122, can send and receive user (the wireless terminal 10) the message using the same IM application 122 It is configured. Specifically, the radio terminal 10 receives a message over the wireless multi-hop network 60 as shown in FIG. IM application 122 of the wireless terminal 10 receives a received message from the lower layer (the radio transceiver 108 and baseband processor 102), account list the sender account ID of the message stored in the wireless terminal 10 (friends Friends or buddies) and against, Xinyuan account ID to display a message for the user if included in the account list, it included a non-display a message if not. Accounts list is included in the account data 124, stored in the memory 106.
[0042]
　Furthermore, the wireless terminal 10 and IM client, abnormal inaccessible to the IM server system 50, by executing a predetermined activation procedure in the wireless terminal 10 without going through the IM server system 50, a radio special account It is configured to be activated in the terminal 10. Here, the activation of special account involves to send special messages to the sender a special account from the radio terminal 10 without via the IM server system 50.
[0043]
　Figure 5 is a flowchart illustrating an example of the activation procedure of the special account. In step S21, the wireless terminal 10 as the IM client, in response to the activation procedure is performed correctly, activating in the wireless terminal 10 special account. Correctness of activation procedure may be verified along the way shown in FIG. In step S31 in FIG. 6, the radio terminal 10 as IM clients, whether activation procedure performed by the user is correct, using activated verification data 123 stored in the memory 106 of the wireless terminal 10 verification to. Activating the verification data 123 includes information necessary to verify the activation procedure. For example, activation verification data 123 includes position information indicating where to run the activation procedure usually account ID activation is permitted, and threshold data used for numerical determination for activation. If it is confirmed the correctness of the activation procedure (YES in step S32), the radio terminal 10 as the IM client activates special account (step S33). On the other hand, if it can not verify the correctness of the activation procedure (NO in step S32), the radio terminal 10 as IM client rejects the activation of special account (step S34).
[0044]
　To return the description will be continued Figure 5. In step S22, the wireless terminal 10 as the IM client, a special message to the sender a special account, and transmits the radio terminal 10 without via the IM server system 50. Wireless terminal 10 may send a special message to the wireless multi-hop network 60 as shown in FIG. The special message is received by the other radio terminals 10 participating in the wireless multi-hop network 60. The other wireless terminals 10 are running the same IM application 122, and the other when the account list of the wireless terminal 10 (friends Friends or buddies) contains the special account, the received special message the other wireless terminals It is displayed for 10 users.
[0045]
　As understood from the above description, the wireless terminal 10 according to this embodiment, even abnormal can not access the IM server system 50 can activate a special account in the wireless terminal 10. In other words, the radio terminal 10, even though you do not have access to IM server system 50 of the IM service operator, it is possible to use a special account. Thus, for example, the wireless terminal 10, even abnormal can not access the IM server system 50 may send a special message to the sender of the special account. Further, for example, when the wireless multi-hop operation disaster, it is possible to send a special message to the sender a special account from the radio terminal 10.
[0046]
　Then the following describes several embodiments of the activation procedure of the special account. These examples may be used alone, it may be used in combination.
[0047]
　In one example, the wireless terminal 10 in the activation procedure, it may be determined whether the correct password by the user (passcode) is entered. However, only with the password authentication, there may be a risk of spoofing by password of leakage. In addition, there may be a risk that can not be activated a special account to forget the password. In addition, it may be necessary protection system that prevents activation of the special account to be a special situation, such as a disaster. Furthermore, it may be preferable to be prevented that the same special account is activated redundantly in the wireless terminal 10 differ. To address at least one of these additional challenges, in combination with or instead of password authentication password authentication, it may be the use one or more other approaches described below.
[0048]
　In one example, the wireless terminal 10 in the activation procedure, may determine whether the wireless terminal 10 is located at a predetermined location or area. For example, the wireless terminal 10 uses the position information acquired by the GPS receiver 109 may determine whether the wireless terminal 10 is located at a predetermined location or area. Further, the wireless terminal 10 uses the geographical indication in the normal account is included in the messages received from another account, determining whether the radio terminal 10 is located in the location or area previously determined it may be. For example, the wireless terminal 10, on the condition that the radio terminal 10 is located in a specific city or in a particular municipality specified location (such as location of the office), to activate the special account assigned to the specific city it may be. For example in combination with password authentication by using the position authentication of the wireless terminal 10, it can contribute to prevent spoofing by a password leakage. Further, by using the position authentication of the wireless terminal 10 in place of password authentication, it is possible to avoid the situation that can not activate the special account for forgotten passwords.
[0049]
　In one example, the wireless terminal 10 in the activation procedure may be utilized behavior of other wireless terminals 10. Specifically, the radio terminal 10, in the activation procedure, also determine whether it has received a message which includes a predetermined display to be set to the abnormality from the other radio terminals 10 around good. To avoid an erroneous determination, the wireless terminal 10 receives the number or the reception rate of messages includes a predetermined display may determine whether more than a predetermined threshold value. Predetermined display, for example, may indicate that a disaster such as an earthquake has occurred (disaster flag). The predetermined display may indicate that IM application 122 is the operation mode for message exchange without using the IM server system 50 (ad hoc mode). Thus, when not abnormal, it is possible to prevent the special account is accidentally or intentionally activated.
[0050]
　In one example, the wireless terminal 10 in the activation procedure, it may be determined whether it has received a predetermined alarm message. Predetermined alarm message, for example, may be a display relating to 3rd Generation Partnership Project Public Warning System defined in (3GPP) (PWS). PWS is used in Japan Earthquake and Tsunami Warning System (ETWS), used in the North America Commercial Mobile Alert System (CMAS), used in Korea Korean Public Alert System (KPAS), and the EU-ALERT to be used in European countries including. Thus, when not abnormal, it is possible to prevent the special account is accidentally or intentionally activated.
[0051]
　In one example, the wireless terminal 10 in the activation procedure, a special message to the sender a special account may determine that it is not received at the wireless terminal 10. This can prevent the same special account is activated redundantly in the wireless terminal 10 differ.
[0052]
　Then, in the following description of some embodiments of a procedure for deactivating the special account after the special account is activated. Deactivation of the special account includes sending a special message not via the IM server system 50 is inhibited. Specific examples of the deactivation procedure shown below, may be used alone, it may be used in combination.
[0053]
　In one example, the wireless terminal 10, in response to the wireless terminal 10 is out of the predetermined location or area, or deactivates the special account in the radio terminal 10.
[0054]
　In one example, the wireless terminal 10, in response to the radio terminal 10 (radio transceiver 107 or 108) is disconnected from the communication network may deactivate the special account. In other words, the radio terminal 10, in response to the radio terminal 10 is disconnected from the wireless multi-hop network 60, it may be inactivated special account in the radio terminal 10.
[0055]
　In one example, the wireless terminal 10, in response to receiving an instruction from the IM server system 50 may deactivate the special account in the radio terminal 10.
[0056]
　In one example, the wireless terminal 10, a denial message indicating that not approve the special account in response to receiving from the other radio terminals 10 around, may be inactivated special account in the radio terminal 10. This allows suppressing the unintended use of special account (e.g., abuse by spoofing).
[0057]
　Note that in some implementations, the activation verification data 123 for verifying the activation procedure or it may be defined (created) by the wireless terminal 10 itself to perform the activation procedure. Alternatively, transmission in some implementations, any of the wireless terminal 10 defines an activation procedure or activation verification data 123 (created), this in addition to the radio terminal 10 to execute the activation procedure it may be.
[0058]

　In the present embodiment, the procedure for defining in any of the wireless terminal activation procedure for activating special account described in the first embodiment. 7 and 8 show an example of the configuration of a system including a radio terminal 70 according to the present embodiment. As shown in FIGS. 7 and 8, exemplary configuration of a system according to this embodiment may be similar to Figures 1 and 2 above.
[0059]
　Wireless terminal 70 according to this embodiment, defines the activation procedure for activating special account, create an activation verification data 123 based on the defined activation procedure, the activation verification data 123 It is configured to transmit to the radio terminal 10 described in the first embodiment. As already explained, activates the verification data 123 is used in authentication procedures for activating the special account in the wireless terminal 10.

In step S42, the activation verification data 123 created, and transmits the special account to the radio terminal 10 activation is permitted.
[0061]
　In some implementations, the wireless terminal 70 may transmit an activation verification data 123 via the IM server system 50 to the radio terminal 10. Further, in some implementations, the wireless terminal 70 may transmit an activation verification data 123 via the wireless multi-hop network 60 to the radio terminal 10. Further, in some implementations, the wireless terminal 70, direct communication without through other devices or terminals (peer-to-peer (P2P) communication) by, for example, Wi-Fi direct, Infrared Data Association (IrDA) , or Bluetooth (registered trademark), by may send an activation verification data 123 to the radio terminal 10. Activating the verification data 123, appropriately coded (e.g., two-dimensional bar code) or may be filed.
[0062]
　Definition and transmission of activation verification data 123 activation procedure by the wireless terminal 70 may be performed at any timing. Thus, for example, without activation procedures have been defined before the abnormality occurs not access the IM server system 50 can allow the use of special account not through the IM server system 50. That is, in some implementations, the definition and transmission of activation verification data 123 activation procedure by the wireless terminal 70 may be executed in response to an abnormality inaccessible occurs in IM server system 50.

Accordingly, even if the wireless terminal 70 is utilized in an unintended third party, the third party by the special account can be prevented from being activated.
[0065]
　As an example, the predetermined authentication procedure may include receiving a message that includes a predetermined display to be set to the abnormality from the surrounding other radio terminals. To avoid an erroneous determination, the wireless terminal 70 receives the number or the reception rate of messages includes a predetermined display may determine whether more than a predetermined threshold value. Predetermined display, for example, may indicate that a disaster such as an earthquake has occurred (disaster flag). The predetermined display may indicate that IM application 122 is the operation mode for message exchange without using the IM server system 50 (ad hoc mode). Thus, when not abnormal, it is possible to prevent the activation procedure of the special account is accidentally or deliberately defined.
[0066]
　As another example, the wireless terminal 70, by being authorized from a plurality of wireless terminals may obtain authorization to define the activation procedure of the special account. Specifically, the radio terminal 70, in response to receiving an acknowledgment message from a plurality of wireless terminals may obtain authorization to define the activation procedure. Accordingly, even if the wireless terminal 70 is utilized in an unintended third party, the third party by the special account can be prevented from being activated. Also, when not abnormal, it is possible to prevent the activation procedure of the special account is accidentally or deliberately defined.
[0067]
　In some implementations, the wireless terminal 70 to define the activation procedure of the special account may suppress the special account is activated in the wireless terminal 70 itself. Accordingly, even if the wireless terminal 70 is utilized in an unintended third party, the third party by the special account can be prevented from being activated.
