1. A method for receiving data in a user equipment (UE) in a mobile content network, the method comprising:
- transmitting a request message, which requests a content, to a first digital unit (DU);
receiving an internet protocol (IP) add message, including information of a second DU which caches the requested content, from the first DU;
updating a stream control transmission protocol (SCTP) connection based on the information of the second DU included in the IP add message; and
receiving data from the second DU using the updated SCTP connection.

Abstract
A method for receiving data in a User Equipment (UE) in a mobile content network is provided. The method includes transmitting a request message, which requests a content, to a first Digital Unit (DU), receiving an Internet Protocol (IP)_ADD message, including information of a second DU which caches the content, from the first DU, updating a Stream Control Transmission Protocol (SCTP) connection according to the information of the second DU included in the IP_ADD message, and receiving data from the second DU using the updated SCTP connection.
