    摘要: A method and system establish a bi-directional tunnel through direct communication between a tunnel end point (TEP) and a user node without user assistance. The method includes: operating the user node in order to establish the bi-directional tunnel, wherein operating the user node includes: requesting network information necessary for establishing the bi-directional tunnel to the DHCP server; when the user node receives the network information from the DHCP server, establishing a unidirectional tunnel from the user node to the TEP based on the received network information; requesting one of the TEPs to establish the unidirectional tunnel; and when the user node receives a router advertisement (RA) message of a second network with which the user node wishes to communicate from the TEP required to establish the unidirectional tunnel, establishing an address of the user node in the second network.

    摘要: Provided is data transmission method and apparatus. A method for transmitting data from a first device to a second device includes detecting information on a communication environment of the first device; receiving information on a communication environment of the second device from the second device; and adjusting the QoS of the data transmission in an application layer based on at least one of the information on the communication environment of the first device and the information on the communication environment of the second device. Accordingly, when a sender transmits data to a receiver, the QoS of data transmission can be adjusted by considering communication environments of the sender and the receiver, and thus optimized data transmission can be achieved.

    摘要: A method and apparatus for communicating data. The method of receiving data by a first device from a second device includes generating a session initiation protocol (SIP) message including information on a data reception environment of the first device; transmitting the generated message to the second device; and receiving data transmitted by the second device based on the transmitted information. Accordingly, data transmission in consideration of a reception environment of a device for receiving data is possible, so that the quality of a data service is guaranteed.

    摘要: A method of and apparatus for constructing a user profile using a content tag, a method of recommending digital content by using a user profile including a tag included in the digital content and a preference value for the tag. According to the methods and apparatus, a user profile is generated by using a content tag, and thus the taste of the user according to digital content consumption can be expressed in more varied ways. Also, by suggesting a method of generating a tag from web content, construction of a user profile for digital content having no tag is enabled. Furthermore, a tag extracted from digital content used by a user is included in a profile and it can be used for a variety of purposes, such as expansion of a comparison scope, use of preference keywords, providing of content links, and expansion of search scope.
