    Abstract: The present invention relates to a method and a system for providing a sponsored service on an IMS-based mobile communication network, and comprises the steps of: a sponsored service client transmitting to a sponsored service server a sponsored service start request message; the sponsored service server determining the validity of the sponsored service after receiving the start request message; transmitting to the sponsored service client a sponsored service start acceptance message when the sponsored service server determines the sponsored service as valid; generating a sponsored service between the sponsored service client and an Internet service provider server; the sponsored service server generating charged fee information and transmitting the charged fee information to an authentication/authorization/accounting (AAA) server, when the sponsored service client requests termination of the sponsored service; and terminating the sponsored service session. According to the present invention, the sponsored service, in which a third paπy Internet service provider can pay the cost using the mobile communication network instead of a wireless user equipment subscriber, can be provided, and the quality of the service can be dynamically controlled from the point the Internet service is provided.

    Abstract: A method of transferring and receiving data by a mobility management entity (MME) in a mobile communication system according to an embodiment of the present invention includes receiving, from equipment, a message that includes the address of an XML configuration access protocol (XCAP) and is used to access an Internet packet data network (PDN); checking any one of subscription information on the equipment and a network carrier policy, on the basis of the received message; and delivering a create session request message to a gateway on the basis of the received message if the equipment is accessible to the PDN as the result of the check, wherein the create session request message includes an indicator that accesses the XCAP server. according to an embodiment, roaming equipment may transfer and receive an XCAP related message. Moreover, as the roaming equipment receives the XCAP related message, the present invention has an effect of being able to prevent undesired traffic due to another data packet from occurring.

    Abstract: A method for encoding streaming data according to one embodiment of the present invention comprises: a step of dividing a forward error correction (FEC) source block into one or more FEC sub-blocks; a first encoding step of FEC encoding said one or more FEC sub-blocks; a second encoding step of encoding said FEC source block; and a step of generating third encoded data including first encoded data encoded in the first encoding step and second encoded data encoded in the second encoding step. According to one embodiment of the present invention, a streaming service can be smoothly provided to multiple users in various environments or in a communication environment that varies according to movement or changes in a communication state. Further, a plurality of pieces of parity information can be transmitted to provide a streaming service which is capable of high reliability data recovery.
