Abstract
There is disclosed a notification method in a communication system of notifying specific multifunctionality information between terminal stations. An expansion code is generated from both a user input code and a function identification code corresponding to a specific function. A transmission frame including the expansion code is also generated and transmitted to at least one of the terminal stations.
Claims17
A communication device, comprising:
- a transmitter configured to transmit a first management frame including a Service Set Identifier (SSID) field, the first management frame received by another communication device,
- wherein the SSID field identifies a service set and a value of the SSID field includes a function identification code indicating a wireless communication function outside the IEEE 802.11 specification, and
- wherein the wireless communication function can be used for communication between the communication device and the another communication device when the function identification code is identified by the another communication device;
- and further comprising:
- a receiver configured to receive a second management frame sent in response to the first management frame;
- and
- circuitry configured to determine whether the wireless communication function can be used based on the second management frame.

A communication device, comprising:
- a receiver configured to receive a first management frame including a Service Set Identifier (SSID) field, the first management frame transmitted by another communication device,
- wherein the SSID field identifies a service set and a value of the SSID field includes a function identification code indicating a wireless communication function outside the IEEE 802.11 specification, and
- wherein the wireless communication function can be used for communication between the communication device and the another communication device when the function identification code is identified by the communication device and further comprising:
- a transmitter configured to transmit a second management frame in response to the first management frame, the second management frame generated based on a content of the first management frame,
- wherein the another communication device determines, based on the second management frame, whether the wireless communication function can be used.

A communication method, comprising:
- transmitting, by a transmitter of a communication device, a first management frame including a Service Set Identifier (SSID) field, the first management frame received by another communication device,
- wherein the SSID field identifies a service set and a value of the SSID field includes a function identification code indicating a wireless communication function outside the IEEE 802.11 specification, and
- wherein the wireless communication function can be used for communication between the communication device and the another communication device when the function identification code is identified by the another communication device:
- and further comprising:
- receiving, by a receiver, a second management frame sent in response to the first management frame;
- and
- determining, by circuitry, whether the wireless communication function can be used based on the second management frame.
