Abstract

A method, computer readable medium and serving node includes an interface configured to exchange data with a user equipment and with a gateway node of a network; and a processor. The processor is configured to implement a classifier function for intercepting a request from the user equipment, and for analyzing whether the request complies with pre-established categorization rules, a request analyzer function for analyzing the request when the request complies with the pre-established categorization rules and for selecting one mode of plural available modes, and an application function for requesting a quality of service, QoS, bearer to be established between the serving node and the user equipment when the selected mode includes a QoS requirement.

Claims

1. A serving node in a telecommunication network, the serving node comprising:

an interface configured to exchange data with a user equipment and with a gateway node of the network; and

a processor connected to the interface and configured to implement;

a classifier function for intercepting a request from the user equipment, wherein the request is related to a desired content, and for analyzing whether the request complies with pre-established categorization rules,

a request analyzer function for analyzing the request when the request complies with the pre-established categorization rules and for selecting one mode of a plurality of available modes, wherein each mode is related to performance indicators associated with the desired content, and wherein the plurality of available modes includes at least a mode characterized by a first cache to provide the desired content being inside the serving node, and

an application function for requesting a quality of service (QoS) bearer to be established between the serving node and the user equipment when the selected mode includes a QoS requirement; and

wherein the interface is configured to send the QoS bearer request to the gateway node.

2. The serving node of claim 1, wherein the request analyzer function analyzes whether the request includes a content request and the application function sends a trigger to the gateway node for initiating the QoS bearer.

3. The serving node of claim 1, wherein the processor is further configured to select the mode for the desired content based on one or more of a latency, round trip time, or traffic load parameters in the network.

4. The serving node of claim 1, further comprising:

the first cache connected to the processor and configured to store the desired content.

5. The serving node of claim 4, wherein the plurality of available modes includes four predefined modes, and the mode characterized by the first cache to provide the desired content being inside the serving node is a third mode and wherein the four predefined modes further include:

a first mode characterized by the QoS bearer being initiated by the network and a second cache to provide the desired content being outside the serving node,

a second mode characterized by the second cache to provide the desired content being outside the serving node, and

a fourth mode characterized by the first cache to provide the desired content being inside the serving node and the QoS bearer being initiated by the serving node.

6. The serving node of claim 1, wherein the processor is configured to implement a configuration function, and wherein the configuration function controls the pre-established categorization rules.

7. The serving node of claim 1, wherein the serving node is a radio network controller or an eNodeB.

8. A telecommunication network comprising:

a serving node;

a gateway node connected by a first bearer to the serving node; and

a policy node connected to the gateway node and configured to provide policy rules for multimedia content being provided in the network; and

wherein the serving node comprises;

an interface configured to exchange data with a user equipment and with the gateway node, and

a processor connected to the interface and configured to implement;

a classifier function for intercepting a request from the user equipment, wherein the request is related to a desired content, and for analyzing whether the request complies with pre-established categorization rules,

a request analyzer function for analyzing the request when the request complies with the pre-established categorization rules and for selecting one mode of a plurality of available modes, wherein each mode is related to performance indicators associated with the desired content and wherein the plurality of available modes includes at least a mode characterized by a first cache to provide the desired content being inside the serving node, and

an application function for requesting a quality of service (QoS) bearer to be established between the serving node and the user equipment when the selected mode includes a QoS requirement, and

wherein the interface is configured to send the QoS bearer request to the gateway node.

9. The network of claim 8, wherein the request analyzer function analyzes whether the request includes a content request and the application function sends a trigger to the gateway node for initiating the QoS bearer.

10. The network of claim 8, wherein the processor is further configured to select the mode for the desired content based on one or more of a latency, round trip time, or traffic load parameters in the network.

11. The network of claim 8, further comprising:

the first cache connected to the processor and configured to store the desired content.

12. The network of claim 11, wherein the plurality of available modes includes four predefined modes, and the mode characterized by the first cache to provide the desired content being inside the serving node is a third mode and wherein the four predefined modes further include:

a first mode characterized by the QoS bearer being initiated by the network and a second cache to provide the desired content being outside the serving node,

a second mode characterized by the second cache to provide the desired content being outside the serving node, and

a fourth mode characterized by the first cache to provide the desired content being inside the serving node and the QoS bearer being initiated by the serving node.

13. The network of claim 11, wherein the processor is further configured to supply the desired content from the first cache directly to the user equipment.

14. The network of claim 8, wherein the processor is configured to implement a configuration function, and wherein the configuration function controls the pre-established categorization rules.

15. A method for providing content with various quality of service (QoS) directly from a serving node in a telecommunication network, the method comprising:

intercepting at the serving node a request from a user equipment, wherein the request is related to a desired content;

analyzing the request to determine whether the request complies with pre-established categorization rules;

selecting one mode of a plurality of available modes based on information found in the request, wherein each mode is related to performance indicators associated with the desired content, and wherein the plurality of available modes includes at least a mode characterized by a first cache to provide the desired content being inside the serving node;

requesting a QoS bearer to be established between the serving node and the user equipment when the selected mode includes a QoS requirement;

establishing the QoS bearer between the serving node and the user equipment; and

providing the desired content to the user equipment from the first cache of the serving node.

16. The method of claim 15, further comprising:

implementing a request analyzer function in the serving node to analyze whether the request includes a content request; and
