A method and apparatus for automatically generating/changing Wireless Local Area Network (WLAN) access information are provided. The apparatus includes an access information management database for storing pre-registered WLAN access information of a plurality of WLAN Access Points (APs). The apparatus also includes an access information collector for collecting information for WLAN APs being accessible at a current position of the apparatus, and an access information analyzer for analyzing the collected information, and creating a list of the accessible WLAN APs. The apparatus further includes a comparator for comparing the list with the WLAN access information to determine if the WLAN APs match. The apparatus additionally includes an access information automatic changer for automatically changing current WLAN access information according to matched APs. The apparatus includes an access information generator for automatically generating new WLAN access information when no WLAN access information is matched with the APs.

Mobile terminal apparatus for automatically generating/changing wireless local area network (WLAN) access information and method for controlling 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.

Dual-modem mobile equipment and communication method using the same

An apparatus and a method for transmitting/receiving data in a dual mode terminal having a host modem and a slave modem are provided. In the method, when an external apparatus generates data, the host modem receives the generated data. The host modem determines a destination of the received data. The host modem forwards the received data to the determined destination.

Apparatus and method for transmitting/receiving data in dual mode terminal

A method and apparatus transmits and receives a service in a wireless communication system by acquiring Quality of Service (QoS) information. A packet is received through a direct communication with a terminal equipment providing a service. When the received packet includes a new destination Internet Protocol (IP) address different from a previously received packet, one or more service quality identifiers corresponding to the received packet are identified. The identified service quality identifiers are transmitted to the terminal equipment, and a service quality identifier corresponding to a service category selected by a user from the identified service categories is received from the terminal equipment. QoS information corresponding to the received service quality identifier is determined and used to generate a radio link between the mobile equipment and a mobile communication network. And the service is received through the radio link.

Method and apparatus for transmitting and receiving service in a wireless communication system

An apparatus and a method for transmitting/receiving a packet in a dual modem mobile communication terminal support data communication using both a host modem and a slave modem by additionally driving the slave modem when packet traffic is heavy. In the method for transmitting/receiving, at a host modem, a packet in a mobile communication terminal that includes the host modem and a slave modem, when a packet is received under a state where only the host modem is driven, it is determined whether a buffer count of the host modem is greater than a reference value. When the buffer count of the host modem is greater than the reference value, the slave modem is additionally driven and the received packet is provided to the slave modem.

Apparatus and method for transmitting/receiving packet in dual modem mobile communication terminal

Provided is a method for setting up a route path between source and destination nodes in a mobile ad hoc network. The source node transmits a RREQ message to the destination node, which transmits a RREP message to the source node. A first intermediate node having failed to transmit the original RREP stores the original RREP, and generates and transmits a PRREQ message, to neighbor intermediate nodes. If an ID of the PRREQ and an original IP address included in the received PRREQ are identical to those of the RREQ received from the source node, a second intermediate node receiving the PRREQ generates and transmits a PRREP message corresponding to the PRREQ to the first intermediate node. If a partial route path is set up between the first and second intermediate nodes, the first intermediate node transmits the original RREP to the source node, which completes setup of the route path.
