Abstract

A method for updating a connection profile in a content delivery service by a dynamic content delivery (DCD) terminal, comprises: receiving, from a server, a connection profile update message including a connection profile; transmitting, to the server, a connection profile update confirmation message in response to the reception; transmitting, to the server, a session deactivation request message based on the connection profile; and transmitting, to another server, a session activation request message base on the connection profile.

Claims

1. A method for updating a connection profile in a content delivery service, comprising:

establishing, by a mobile terminal, a session for content delivery service with a server;

receiving, by the mobile terminal from the server, a connection profile update message for updating a connection profile during the session;

checking, by the mobile terminal, whether at least one of a name of the connection profile and a profile element exists in the received connection profile update message;

if the received connection profile update message includes the name of the connection profile and the profile element, updating, by the mobile terminal the connection profile, transmitting, to the server, a session deactivation request message, and transmitting, to another server, a session activation request message based on the updated connection profile; and

if the received connection profile update message does not include the profile element, deleting the connection profile.

2. The method of claim 1, further comprising:

checking, whether the session stays active to be used by a client application in the mobile terminal,

wherein the transmitting of the session deactivation request message while the session is active is not required.

3. The method of claim 1, wherein the connection profile is a connection profile for a DCD-3 interface, the session deactivation request message is a Client Deactivation Request message,

wherein the method further comprises:

transmitting, to another server, a session activation request message, and

wherein the session activation request message is a Client Activation Request message.

4. The method of claim 1, further comprising:

receiving, from the server, a session deactivation response message; and

receiving, from another server, a session activation response message,

wherein the session deactivation response message is a Client Deactivation Response message, and

wherein the session activation response message is a Client Activation Response message.

5. The method of claim 1, wherein the connection profile comprises an address of another server.

6. The method of claim 1, wherein the connection profile is located under an application profile.

7. The method of claim 1, further comprising:

transmitting, to the server, a connection profile confirmation message in response to receiving the connection profile update message,

wherein the step of performing the update procedure is performed in an interchanged order with a step of transmitting a connection profile confirmation message.

8. The method of claim 1, wherein in the step of performing the update procedure, an element or a parameter of the connection profile is changed based on the at least one value of the connection profile inside the connection profile update message.

9. The method of claim 1, wherein if the connection profile includes no element or no parameter or if the received connection profile update message includes only the name of the connection profile, deleting the connection profile.
