Service continuity during outbound handover from a home network base station with local internet protocol access

1. A method for managing access with a mobility management entity, comprising:

generating a local network access disable notification message element to provide available options to a mobile system for establishing packet data network connectivity upon an access loss to a home network base station, where the home network base station provides access for the mobile system to a local area home network using a local access protocol and provides access to a core network; and

sending the local network access disable notification message element to the mobile system upon an imminent local network access loss event.

2. The method of claim 1 , wherein the local network access disable notification message element has a cause field describing the imminent local network access loss event.

3. The method of claim 1 , wherein the local network access disable notification message element has an access point name field indicating a packet data network.

4. The method of claim 1 , wherein the local network access disable notification message element has a traffic flow template indicating a data traffic type for a data packet bearer to be routed through a packet data network.

5. The method of claim 1 , further comprising:

associating based on traffic statistics for at least one available home network alternative an access point name field indicating a packet data network and a traffic flow template indicating a data traffic type.

6. The method of claim 1 , further comprising:

sending the local network access disable notification message element to the mobile system after the local network access loss.

7. The method of claim 1 , further comprising:

receiving a closed subscriber group membership request message element from a mobile system; and

extending to the mobile system a subscription period for a closed subscriber group of the home network in response to the closed subscriber group membership request message element.

8. The method of claim 1 , further comprising:

receiving a closed subscriber group membership request message element from a mobile system; and

directing the home network to handover the mobile system to a home network designate indicated in the closed subscriber group membership request message element.

9. A mobile system for accessing to a home network, comprising:

a transceiver that receives from a mobile management entity a local network access disable notification message element providing available options for establishing packet data network connectivity upon an access loss to a home network base station, where the home network base station provides access for the mobile system to a local area home network using a local access protocol and provides access to a core network;

a processor that executes a connectivity action based upon the local network access disable notification message element.

10. The mobile system of claim 9 , wherein the local network access disable notification message element has at least one of a cause field describing a cause of the access loss.

11. The mobile system of claim 9 , wherein the processor selects a data traffic type as indicated by a traffic flow template field to execute connectivity for service continuity.

12. The mobile system of claim 9 , wherein the processor selects a packet data network through an access point name field to execute connectivity for service continuity.

13. The mobile system of claim 9 , wherein the processor executes connectivity for a plurality of data traffic types to be routed on a plurality of packet data bearers through a plurality of packet data networks based on the local network access disable notification message element.

14. The mobile system of claim 9 , wherein the processor generates a closed subscriber group membership request message element to request further connectivity action.

15. The mobile system of claim 14 , wherein the closed subscriber group membership request message element has an expiry time received from a user indicating an extension to a subscription period.

16. The mobile system of claim 14 , wherein the closed subscriber group membership request message element has a closed subscriber group identifier indicating a home network designate.

17. The mobile system of claim 14 , wherein the closed subscriber group membership request message element is appended to a message sent to a mobility management entity.

18. A home network base station that connects to a mobile system, comprising:

a network interface that receives from a mobile management entity an access redirection event instruction generated in response to a closed subscriber group membership request message element from the mobile system;

a processor that decodes the access redirection event instruction to determine a connectivity action and executes the connectivity action.

19. The home network base station of claim 18 , wherein the access redirection event instruction has an expiry time and the connectivity action is to extend the subscription period.

20. The home network base station of claim 18 , wherein the access redirection event instruction has a closed subscriber group restriction information and the connectivity action is to initiate handover to a home network indicated by the closed subscriber group restriction information.
