摘要： A method of operating a communication system, comprising the steps of: receiving a first OSI layer two packet from a first network interface; determining transmission type of the first OSI layer two packet; determining whether to send a second OSI layer two packet according to the transmission type, origin and destination of the first OSI layer two packet; determining destination address and transmission type of the second OSI layer two packet when determined to send the second OSI layer two packet; and sending the second OSI layer two packet through a second network interface when determined to send the second OSI layer two packet; wherein when the first OSI layer two packet is encapsulated in at least one layer three packet, the second OSI layer two packet is not encapsulated in any OSI layer three packet; and wherein when the first OSI layer two packet is not encapsulated in any Open Systems Interconnection (OSI) layer three packet, the second OSI layer two packet is encapsulated in at least one OSI layer three packet.

摘要： Methods and apparatus for processing data packets originated from a mobile computing device to destinations at a wireless network node. The wireless network node receives an access request from the mobile computing device for the data packet transmission to the destinations and determines an identifier of the mobile computing device. The wireless network node then determines whether the identifier is in a wireless network node database. When the identifier is not in the wireless network node database, the wireless network node suspends to process data packets received from the mobile computing device and communicates with a server to determine whether status of the mobile computing device in a server database is the first state.

摘要： The present invention discloses a method and system for processing a first layer two packet converting a first layer two packet to a first unicast layer two packet at a wireless access point. The wireless access point receives first one or more layer three packets and extracts a first layer two packet from the first one or more layer three packets. If the first layer 2 packet is a multicast packet and it satisfies the predefined rule, the first layer two packet is converted to a layer two unicast packet with a first destination address and send to a Local Area Network (LAN) network interface. If the first layer two packet does not satisfy the predefined rule, it is broadcast to one or more LAN network interface. When the first layer two packet is not a multicast packet, it is sent to its corresponding destination address through one or more LAN network.
