Provided is an apparatus for searching accessible wireless networks in a software-defined radio (SDR) terminal, a method thereof, and a computer-readable recording medium for storing a program executing the method. The apparatus includes: a hardware platform; a network search executable code storing means for storing a network search executable code having at least one of mode search executable codes; a search shape information storing unit for storing search shape information necessary for network search; a network search control means for arranging each of the mode search executable codes from the network search executable code storing means at the hardware platform by using the search shape information from the search shape information storing means and searching a network according to a search mode by executing the arranged mode search executable codes; and a network search result storing means for storing network search results from the network search control means.

Provided are an apparatus for a dynamic header compression and a method thereof. The method for a dynamic header compression includes: receiving a received packet having a header from an upper layer; comparing header information of the received packet with header information of a previous packet; when a suppression part of the received packet is the same as a suppression part of the previous packet, compressing the received packet based on a predetermined header suppression rule; and when the suppression part of the received packet is not the same as the suppression part of the previous packet, transmitting the received packet without compression.

Apparatus for dynamic header compression and method thereof

In a portable Internet system, packets are classified into a first packet classified as a transport connection identifier (CID) and a second packet that is not classified as a transport CID by using an established packet classification rule. An application program of the second packet is searched from a plurality of application programs by using the header information of the second packet in the portable Internet system. QoS parameter information for the searched application program is obtained from a plurality of QoS parameter informations corresponding to the plurality of application programs.

Apparatus and method for classifying quality-of-service of packet in portable internet system

A terminal including a packet detecting unit, a user input/output unit, a CID managing unit, and a data storing unit is disclosed. The packet detecting unit determines whether a packet can be classified by a pre-established packet classification rule or a packet cannot be classified by the rules. For packets that cannot be classified, the user input/output unit receives QoS information from a user. The CID managing unit generates a new packet classification rule for the unclassified packet, checks a CID in a data storing unit, the CID having the same QoS class as that of the QoS parameter input through the user input/output unit, and determines whether to generate a new CID or to add the new packet classification rule to the pre-established CID. The data storing unit storing unit Stores the new packet classification rule generated by the CID managing unit and information on the CID.
