Dual-modem mobile equipment and communication method using the same
A communication method uses a dual-modem Mobile Equipment (ME) that includes a cellular modem communicable with a cellular system and a Wireless Local Area Network (WLAN) modem capable of WLAN communication. The method includes registering a Media Access Control (MAC) address of a Terminal Equipment (TE) connected to the cellular modem over a WLAN. The method also includes receiving data from the TE with the registered MAC address at the WLAN modem through a WLAN interface, and transferring the data to the cellular system through the cellular modem. Thus, even a TE with no cellular modem equipped can perform data communication over the cellular network and the pre-registered TE is allowed to transmit and receive data through an ME with a WLAN modem, facilitating efficient use of the limited resources, and the user is allowed to set priorities of TEs, making it possible to ensure QoS of each TE independently.
1. A communication method using a dual-modem mobile equipment (ME) having a cellular modem communicable with a cellular system and a wireless local area network (WLAN) modem capable of WLAN communication, the communication method comprising:
registering, in a terminal list of the cellular modem, a media access control (MAC) address of a terminal equipment (TE) connected over a WLAN;
receiving first data from the TE with the registered MAC address at the WLAN modem through a WLAN interface;
allocating a dedicated channel for the TE with the registered MAC address based on quality of service (QoS) information of the first data;
allocating a dedicated wireless data link resource for the dedicated channel to an individual application;
generating second data by including an internet protocol (IP) address of the TE using the dedicated channel, in the first data;
adding filtering information of a packet for the second data in a packet filter list; and
transmitting the second data to the cellular system through the dedicated channel in the cellular modem.
2. The communication method of claim 1 , wherein registering the MAC address comprises registering a record including the MAC address and information on an internet protocol (IP) address allocated to the TE.
3. The communication method of claim 1 , wherein the filtering information comprises a source IP address, a destination IP address, a source port number, a destination port number, protocol information, and IP information allocated to the TE.
4. The communication method of claim 1 , wherein service priorities are set in a process of allocating the dedicated channel based on the QoS information of the first data.
