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 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.

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.

7. A method for transmitting data in a first Digital Unit (DU) in a mobile content network, the method comprising:
-
receiving a request message, which requests a content, from a User Equipment (UE); determining whether the first DU currently caches the content which the UE requests; routing the request message to a second DU, as a DU which is expected to cache the content which the UE requests, if the first DU does not cache the content which the UE requests; and transmitting an Internet Protocol (IP)_ADD message, including information of the second DU, to the UE. - View Dependent Claims (8, 9, 10, 11, 12, 13)
