Abstract

Various embodiments of the present disclosure relate to a method and apparatus for connecting to multiple Packet Data Networks (PDNs) in a wireless communication system using a Carrier Aggregation (CA) technique. In the wireless communication system using the CA technique for aggregating multiple carriers into one carrier, the wireless communication system may ensure Quality of Service (QoS) of a subscriber by mapping multiple carriers and multiple PDNs on the basis of a dynamic CA carrier. Various embodiments are possible.

First claim

What is claimed is:

1. A method of an electronic device for connecting to multiple Packet Data Networks (PDNs) in a wireless communication system using a Carrier Aggregation (CA) technique, the method comprising:
transmitting, to a core network, information regarding one or more frequency bands and information regarding a first operation policy of the multiple PDNs that is determined based on a state of the electronic device, wherein the information regarding the first operation policy of the multiple PDNs comprises mapping information between at least one frequency band among the one or more frequency bands and at least one PDN among the multiple PDNs;
receiving, from the core network, information regarding a second operation policy of the multiple PDNs that is determined by the core network based on the first operation policy of the multiple PDNs according to a state of the core network; and
configuring a radio bearer for data communication according to the information regarding the second operation policy of the multiple PDNs.

2. The method of claim 1 , wherein the state of the electronic device comprises at least one of a user configuration, a battery state, or a power consumption.

3. The method of claim 1 , wherein the state of the electronic device comprises at least one of a frequency, a bandwidth, user's service quality, a user's subscription fee, a latency, or a jitter.

4. The method of claim 1 , wherein the second operation policy of the multiple PDNs is updated on a real-time basis according to a network environment.

5. The method of claim 1 , wherein a path of the radio bearer is created among the electronic device, an evolved Node B (eNB), a Serving-GateWay (S-GW), and a PDN-GateWay (P-GW).

6. The method of claim 1 , wherein the wireless communication system is a Long Term Evolution (LTE) system.

7. A method of a core network for connecting to multiple Packet Data Networks (PDNs) in a wireless communication system using a Carrier Aggregation (CA) technique, the method comprising:
receiving, from an electronic device, information regarding one or more frequency bands and information regarding a first operation policy of the multiple PDNs that is determined based on a state of the electronic device, wherein the information regarding the first operation policy of the multiple PDNs comprises mapping information between at least one frequency band among the frequency bands and at least one PDN among the multiple PDNs;
determining whether to accept the first operation policy of the multiple PDNs based on a state of the core network;
according to a result of the determination, transmitting, to the electronic device, information regarding a second operation policy of the multiple PDNs that is determined based on the first operation policy of the multiple PDNs according to the state of the core network; and
configuring a radio bearer for data communication according to the second operation policy of the multiple PDNs.

8. The method of claim 7 , wherein the state of the electronic device comprises at least one of a user configuration, a battery state, or a power consumption.

9. The method of claim 7 , wherein the state of the core network comprises at least one of a frequency, a bandwidth, user's service quality, a user's subscription fee, a latency, or a jitter.

10. The method of claim 7 , further comprising updating the second operation policy of the multiple PDNs on a real-time basis according to a network environment.

11. The method of claim 7 , wherein a path of the radio bearer is created among the electronic device, an evolved Node B (eNB), a Serving-GateWay (S-GW), and a PDN GateWay (P-GW).

12. The method of claim 7 , wherein the wireless communication system is a Long Term Evolution (LTE) system.

13. An electronic device for connecting to multiple Packet Data Networks (PDNs) in a wireless communication system using a Carrier Aggregation (CA) technique, the electronic device comprising:
a transmitter configured to transmit, to a core network, information regarding one or more frequency bands and information regarding a first operation policy of the multiple PDNs that is determined based on a state of the electronic device, wherein the information regarding the first operation policy of the multiple PDNs comprises mapping information between at least one frequency band among the frequency bands and at least one PDN among the multiple PDNs;
a receiver configured to receive, from the core network, information regarding a second operation policy of the multiple PDNs that is determined based on the first operation policy of the multiple PDNs according to the state of the core network; and
a processor configured to configure a radio bearer for data communication according to the information regarding the second operation policy of the multiple PDNs.

14. The electronic device of claim 13 , wherein the state of the electronic device comprises at least one of a user configuration, a battery state, or a power consumption.

15. The electronic device of claim 13 , wherein the state of the core network comprises at least one of a frequency, a bandwidth, user's service quality, a user's subscription fee, a latency, or a jitter.

16. The electronic device of claim 13 , wherein a path of the radio bearer is created among the electronic device, an evolved Node B (eNB), a Serving-GateWay (S-GW), and a PDN GW (P-GW).

17. The electronic device of claim 13 , wherein the wireless communication system is a Long Term Evolution (LTE) system.
