1. A method of managing mobility in an Internet Protocol (IP) based network by a mobile station, the method comprising:
- detecting, by the mobile station, a request for allocation of an IP address from an application included in the mobile station;
determining, by the mobile station, a type of the IP address to be allocated to the application based on the request; and
allocating, by the mobile station, the IP address of the determined type to the application,wherein the type of the IP address is determined based on a network to which the IP address to be allocated to the application is anchored,wherein the IP address of the determined type includes one of a first-type IP address anchored to a core network, a second-type IP address anchored to an access network, and a third-type IP address which is not anchored to any network, andwherein the second-type IP address is allocated to the application in response that an anchor distance is shorter than a threshold value, and the second-type IP address is maintained in another access network in response that the mobile station is handed over from the access network to the another access network.

8. A mobile station for managing mobility in an Internet Protocol (IP) based network, the mobile station comprising:
-
an IP stack configured to; detect a request for allocation of an IP address from an application included in the mobile station, determine a type of the IP address to be allocated to the application based on the request, and allocate the IP address of the determined type to the application; and a mobile Application Programming Interface (API) arranged between the IP stack and the application, wherein the type of the IP address is determined based on a network to which the IP address to be allocated to the application is anchored, wherein the IP address of the determined type includes one of a first-type IP address anchored to a core network, a second-type IP address anchored to an access network, and a third-type IP address which is not anchored to any network, and wherein the second-type IP address is allocated to the application in response that an anchor distance is shorter than a threshold value, and the second-type IP address is maintained in another access network in response that the mobile station is handed over from the access network to the another access network. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable recording medium for implementing a program of instructions which, when executed by at least one processor of a mobile station, cause the at least one processor to perform operations, comprising:
-
detecting, by the mobile station, a request for allocation of an IP address from an application included in the mobile station; determining, by the mobile station, a type of the IP address to be allocated to the application based on the request; and allocating, by the mobile station, the IP address of the determined type to the application, wherein the type of the IP address is determined based on a network to which the IP address to be allocated to the application is anchored, wherein the IP address of the determined type includes one of a first-type IP address anchored to a core network, a second-type IP address anchored to an access network, and a third-type IP address which is not anchored to any network, and wherein the second-type IP address is allocated to the application in response that an anchor distance is shorter than a threshold value, and the second-type IP address is maintained in another access network in response that the mobile station is handed over from the access network to the another access network. - View Dependent Claims (16, 17, 18, 19, 20, 21)
