• the message frame that is not interested can be parsed, for example, if A mobile terminal device parses the message frame identifier bit, and finds that the frame is not interested in itself, and can directly discard the remaining part of the message frame and no longer parse, which is beneficial for power saving; and the message frame also provides service related information for the receiver.
• the receiver determines whether it is necessary to connect to the sender to conduct business based on the service related information.
• the message frame is a broadcast message frame, a multicast message frame or a unicast message frame.
• the message frame can be sent out in different manners such as broadcast, multicast, unicast, etc.
• the destination address in the broadcast message frame is the broadcast message address; if the message frame is a group Broadcast message frame, then the destination address in the multicast message frame is the multicast message address.
• the multicast message address can be a special identifier of a group.
• the special identifier can be 48 bits or other bits.
• the message frame is a unicast message frame
• the destination address in the unicast message frame is a unicast message address, specifically, the unicast message address is the MAC address of a certain terminal device.
• the message frame is a control frame, a management frame or a common action frame.
• the message frame may be sent in the form of a control frame, a management frame or a common action frame.
• the message frame may also be sent in other forms.
• the service related information domain is composed of a service type information domain and a service detailed information domain, for example, the type information domain identifies the type of the service, for example: game, chat or other services.
• Type the receiver determines which specific service in the service type category according to the service detailed information field, for example, the detailed information may be a CS game in the game, or may include other information of the CS game, such as game level information, service type information
• the domain and the service detail domain may be subdomains of the service information domain; for the public action frame, the service type information domain, the service detail information domain, and the action frame information domain, where the service type information domain and the service detailed information domain are
• the management frame has the same function as the control frame, and is not described here.
• the receiver determines that the frame is a NAN discovery message frame according to the action frame information field.
