Abstract

The present invention relates to a method and device for setting a selective source IP address. The method for setting a source IP address of a terminal comprises the steps of: receiving an allocation of a plurality of IP addresses from at least one network node; acquiring information on the property of at least one IP address among the plurality of IP addresses; and selecting the source IP address for a flow of the terminal from the plurality of IP addresses on the basis of attribute information of at least one IP address, wherein the attribute information of the IP address can include information on a flow for recommending the use of a corresponding IP address and/or information on a flow for prohibiting the use of the corresponding IP address.

First claim

1 . A method for setting a source internet protocol (IP) address by a user equipment (UE), comprising:
receiving an allocation of a plurality of IP addresses from at least one network node; acquiring attribute information for at least one IP address among the plurality of IP addresses; and selecting a source IP address for a flow of the UE from the plurality of IP addresses on the basis of attribute information for the at least one IP address, wherein the attribute information for the IP address comprises at least one of information on a flow for recommending the use of a corresponding IP address and information on a flow for prohibiting the use of a corresponding IP address.

2 . The method of claim 1 , wherein selecting of the source IP address for the flow of the UE from the plurality of IP addresses on the basis of attribute information for at least one IP address comprises:
determining a user preference for information on the plurality of IP addresses; determining at least one candidate IP address, by the user's preference, among the plurality of IP addresses; and selecting the source IP address for the flow of the UE from the candidate IP address on the basis of the attribute information for the at least one IP address.

3 . The method of claim 1 ,
wherein the attribute information for the IP address further comprises size information of a service coverage area of the network node which allocates the corresponding IP address, and wherein the selecting of the source IP address for the flow of the UE among the plurality of IP addresses on the basis of the attribute information for the at least one IP address comprises:
predicting a use time of an application associated with the flow of the UE,
determining at least one candidate IP address among the plurality of IP addresses on the basis of the predicted use time and the size information of the service coverage area included in the attribute information, and
selecting the source IP address for the flow of the UE from the candidate IP address on the basis of the attribute information for the at least one IP address.

4 . The method of claim 1 ,
wherein the attribute information for the IP address further comprises valid period information indicating a time during which the UE is expected to stay within the service coverage of the network node to which the corresponding IP address is allocated, wherein the valid period information is determined based on the movement speed of the UE, and wherein the selecting of the source IP address for the flow of the UE from the plurality of IPs on the basis of the attribute information for the at least one IP address comprises:
predicting a use time of the application associated with the flow of the UE;
determining at least one candidate IP address among the plurality of IP addresses on the basis of the predicted use time and the validity information included in the attribute information; and
selecting the source IP address for the flow of the UE from the candidate IP address on the basis of the attribute information for the at least one IP address.

5 . The method of claim 1 , wherein acquiring of the attribute information for at least one IP address among the plurality of IP addresses comprises:
requesting the attribute information, by the UE, from the network node which allocates the at least one IP address; and receiving the attribute information for the at least one IP address from the network node.

6 . The method of claim 1 ,
wherein acquiring of the attribute information for at least one IP address among the plurality of IP addresses comprises at least one of receiving the at least one IP address and attribute information for the IP address from a network node for managing the IP address of the UE, and receiving changed attribute information when the attribute information is changed, and wherein the network node for managing the IP address of the UE comprises a node which detects a situation in which the plurality of IP addresses are allocated to the UE.

7 . The method of claim 1 , wherein the information on the flow comprises at least one of a destination domain name, destination port number and a range of destination port numbers, a source port number and a range of source port numbers, a transport layer protocol, continuity of flow, and an IP address reach ability.

8 . A method for allocating an internet protocol (IP) address by a network node, comprising:
generating attribute information for an IP address allocated to a user equipment (UE); and transmitting the attribute information for the IP address to the UE, wherein the attribute information for the IP address comprises at least one of information on a flow for recommending use of a corresponding IP address and information on a flow for prohibiting use of a corresponding IP address.

9 . The method of claim 8 , wherein the attribute information for the IP address further comprises size information of a service coverage area of the network node.

10 . The method of claim 8 , wherein the attribute information for the IP address further comprises valid period information indicating a time during which the UE is expected to stay within the service coverage of the network node, and
the valid period information is determined based on the movement speed of the UE.

11 . A user equipment (UE) apparatus for setting a source internet protocol (IP) address, comprising:
at least one transceiver; and at least one processor operatively coupled to the at least one transceiver, wherein the at least one processor is configured to:
receive an allocation of a plurality of IP addresses from at least one network node,
acquire attribute information for at least one IP address among the plurality of IP addresses, and
select the source IP address for a flow of the UE from the plurality of IP addresses on the basis of the attribute information for the at least one IP address,
wherein the attribute information for the IP address comprises at least one of information on a flow for recommending the use of a corresponding IP address and information on a flow for prohibiting the use of the corresponding IP address.

12 .- 15 . (canceled)

16 . The method of claim 1 , wherein selecting the source IP address for the flow of the UE from the plurality of IP address comprises:
selecting the source IP address by considering at least one of a user preference information and characteristics information of an application.

17 . The UE apparatus of claim 11 , wherein the at least one processor is further configured to:
determine a user preference for information on the plurality of IP addresses, determine at least one candidate IP address, by a user preference, among the plurality of IP addresses, and select the source IP address for the flow of the UE from the candidate IP address on the basis of the attribute information for the at least one IP address.

18 . The UE apparatus of claim 11 ,
wherein the attribute information for the IP address further comprises size information of a service coverage area of the network node which allocates the corresponding IP address, and wherein the at least one processor is further configured to:
predict a use time of an application associated with the flow of the UE,
determine at least one candidate IP address among the plurality of IP addresses on the basis of the predicted use time and the size information of the service coverage area included in the attribute information, and
select the source IP address for the flow of the UE from the candidate IP address on the basis of the attribute information f
