Description

TECHNICAL FIELD [0001] The present invention relates to a ring tone mode switching service and a method for implementing a ring tone mode switching service and a service that automatically switch a ring tone mode of a mobile phone to a vibration mode using a communication protocol and an IEEE802.11 standard protocol. it's service through IEEE802.11 standard protocol frame and its application software}

The present invention relates to a method of defining a communication protocol between an access point and a station by using the IEEE802.11 standard in a space provided with a wireless local area network equipment so that a mobile phone ring tone can be automatically changed, and a service providing method through the communication protocol.

IEEE 802.11 is a technology used in computer wireless networks for wireless local area networks (WLANs), often referred to as WLANs and Wi-Fi, and is the 11th working group of IEEE's LAN / MAN Standards Committee (IEEE 802) The standard technology developed in IEEE 802.11 is a technology designed to overcome the disadvantages of Ethernet, which is currently the main wired LAN type, and it is widely used to minimize unnecessary wiring work and maintenance costs at the end of Ethernet network. Typically, you install a single hotspot in an unclosed (for example, one office), connect an external WAN, backbone switch, and each office hotspot to an Ethernet network. This makes it unnecessary to install and maintain the cable in the office.

According to the IEEE802.11 protocol standard, a wireless communication terminal is collectively referred to as a station, and the wireless local area network space is divided into an independent BSS (Basic Service Sets), which is a communication method between stations, and an Infrastructure BSS (Basic Service Sets), which is a communication method between a station and an access point. The present invention defines a communication protocol between an access point and a station in an infrastructure BSS scheme.

The wireless LAN communication frame format defined in the IEEE802.11 standard is as follows.

It is recognized as Data Frame, Control Frame, and Management Frame according to the field value of Type and Subtype in Frame control field.

Data Frame is a data communication frame for OSI Model Layer 3 protocol defined by ANSI in international standard organization as a frame to communicate or receive service through communication network such as the Internet. An example of the communication frame configuration in data communication is as follows.

The control frame performs the RTS / CTS clearing phase by Layer 2 communication for data communication. This is a procedure for occupying the RF between the access point and the station in the environment using radio frequency as a communication medium. If the RTS (Request to Send) frame is transmitted to reserve the access time, the access point responds with a CTS (Clear to Send) frame to notify that the station transmitting the RTS can transmit data, The data transmission is stopped at the access point responding with CTSFrame as much as the defined time (NAV, Network Allocation Vector). This is referred to as virtual career sensing, and the related time is included. Does not respond.

The management frame includes a beacon frame, a probe request frame, and a probe response frame. A beacon frame indicates that an access point exists in the BSS by transmitting the access point to the BSS in a period of 100 ms. The management point includes information about the wireless network such as a timestamp and an SSID . Since one beacon is generated for each SSID and contains information about BSS and buffered frames, all stations should be able to receive it and the communication bandwidth is transmitted at basic rate. Probe Request Frame is a frame to scan for any access points in the vicinity, and no Ack Frame is generated. The Probe Response Frame is a frame corresponding to the probe request, and includes the capability information of the corresponding BSSID, the country, and the data rate to be supported.

In addition, many frames before Layer 3 data communication are created. The Authentication Frame is a frame for access to the access point by the station, and the De-Authentication Frame is used as a Notification form as a frame for connection termination. The Association Request Frame is created in the Station, and the Association Response Frame has acceptance or rejection information as a response frame to the Association Request at the Access Point. The Frame having the acceptance information includes a Resource for the Station, a Capability , And Association ID (AID). After this frame, the corresponding station transmits a frame to the DS. That is, Layer 3 data communication is executed.

This patent relates to a communication protocol for informing that a ring tone is automatically switched from a voice mode to a vibration mode in a cell phone located in the BSS at an access point using a management frame executed prior to Layer 3 data communication between an access point and a station.

According to an aspect of the present invention, a method for communicating between an access point and a station using a Layer 3 communication protocol requires a wireless security technology for hacking, virus, and Dos attacks, And so a large amount of resources are required. However, the Layer 2 level communication frame is suitable for the purpose of the present patent using communication between the access point and the station since it does not require much consideration of authentication and wireless security.

IEEE802.11 Frame distinguishes Frame through the Type field value and Subtype field value of frame as follows.

If the 2-bit Type field value is "00", it is a Management Frame. If it is "01", it is a Control Frame. If it is "10", it is a Data Frame.

The Control Frame related to this patent has Beacon Frame, Probe Request Frame and Probe Response Frame, and the Subtype field values are "1000", "0100", and "0101" respectively. That is, if the Type field value is "01" and the Subtype field value is "1000", it is recognized as a Beacon Frame. In a Beacon Frame broadcast in an arbitrary space in the BSS at an access point in a period of 100 ms, a Control Frame Subtype field is defined as a value "1101" which is not specified in the IEEE802.11 standard, and the subtype name is defined as "Beacon with vibration mode notice " When a mobile phone equipped with the program installs a program for automatic mode conversion and detects a beacon frame broadcast from the access point, it broadcasts in the BSS to the probe request frame for searching for the access point. At this time, the subtype field value "0100"Quot; 0110 " which is not specified in the IEEE802.11 standard. The " Control Frame Subtype field value " As defined and, Subtype name the "Probe request with vibration message requirement" is defined as, Access point are Probe Request in response to the Frame and sends a Probe Response Frame, The Subtype field value "0101" mobile phone vibration mode and including a value The Control Frame Subtype field value which means to include the message information is defined as a value "0111" not specified in the IEEE802.11 standard, and the Subtype name is defined as "Probe response with vibration notice message "

In this patent, the beacon frame has the value of the subtype field defined as " 0111 " as defined above, and the variable field size as defined in the IEEE802.11 standard is switched to the ring tone vibration mode of the mobile phone set at the access point in the SS ID field The alias inserts the message information and transmits it to the station.

According to the IEEE 802.11 standard, the SS-ID field is as follows. When the Element ID value is "0", 34 bytes are recognized as the SS-ID value.

This table defines Element ID & quot ; 17 & quot ; as & quot ; Vibration mode notification &quot;, and Length of indicated element (in octets) is defined as & quot ; 17-31 & quot; &Quot; 2-257 ". According to this definition, the notification message of ring tone vibration mode set at the access point can have a length from 0 bytes to 255 bytes.

As described above, the present invention is a new service provided between an access point and a station by additionally defining a communication frame in conformity with the IEEE802.11 standard defined by the international standard for wireless local area network. 11 standard protocol, it is possible to provide the communication service as it is and at the same time, by designing the additional communication protocol, it is possible to provide the automatic vibration mode switching service to the stations in the BSS. Can be applied to many public places that need to change from sound mode to vibration mode. The access point can be implemented by updating the firmware and downloading the application (APP) to the station (mobile phone) free of charge.
