Abstract

A method, apparatus and system are provided for acquiring an access point name for an application employing a local Internet protocol breakout service. In one embodiment, the apparatus includes a user management subsystem (820) configured to initiate an Internet protocol application. The apparatus also includes a local breakout service monitoring subsystem (810) configured to monitor availability of a local Internet protocol local breakout service and to obtain an access point name from the local Internet protocol local breakout service when the local Internet protocol local breakout service is available. The apparatus also includes an access point name selection control subsystem (830) configured to bind the access point name to the Internet protocol application.

9. The apparatus as recited in claim 1 wherein said access point name selection control subsystem is configured to obtain an access point name from a gateway capable of providing access from a cellular communication system to an external packet switch network when said local Internet protocol local breakout service is not available.

10. The apparatus as recited in claim 1 wherein said initiation of an Internet protocol application is in response to a network-originated or an apparatus-originated session.

11. An apparatus, comprising:

means for initiating an Internet protocol application;

means for monitoring availability of a local Internet protocol local breakout service;

means for obtaining an access point name from said local Internet protocol local breakout service when said local Internet protocol local breakout service is available; and

means for binding said access point name to said Internet protocol application.

12. The apparatus as recited in claim 11, further comprising:

means for detecting a loss of availability of said local Internet protocol local breakout service;

means for placing on hold and storing said access point name for said Internet protocol application for said local Internet protocol local breakout service;

means for using said access point name for said Internet protocol application from a gateway;

means for detecting restored availability of said local Internet protocol local breakout service;

means for regaining an Internet protocol address from said local Internet protocol local breakout service;

means for setting as a default access point name said access point name obtained from said local Internet protocol local breakout service.

13. A computer program product comprising program code stored in a computer readable medium configured to initiate an Internet protocol application, monitor availability of a local Internet protocol local breakout service, obtain an access point name from said local Internet protocol local breakout service when said local Internet protocol local breakout service is available, and bind said access point name to said Internet protocol application.

14. The computer program product as recited in claim 13 wherein said program code stored in said computer readable medium is configured to detect a loss of availability of said local Internet protocol local breakout service, place on hold and store said access point name for said Internet protocol application for said local Internet protocol local breakout service, use said access point name for said Internet protocol application from a gateway, detect restored availability of said local Internet protocol local breakout service, regain an Internet protocol address from said local Internet protocol local breakout service, and set as a default access point name said access point name obtained from said local Internet protocol local breakout service.
