Abstract

Problems caused by interaction between paging optimization and synchronizing closed subscriber group (CSG) information are mitigated by setting a network indication indicating, for example, that a subscriber is no longer a member of a CSG, but the network has not yet received confirmation that an access terminal associated with the subscriber has been informed of this. A timer-based scheme may be employed for removing a CSG identifier (ID) from the subscriber information for a subscriber once it is determined that the subscriber is no longer a member of the CSG. In addition, a temporary member of a CSG may determine whether it is still a member of a CSG upon expiration of a CSG timer. Also, the frequency with which an access terminal registers may be changed based on various criteria. Furthermore, an allowed CSG list may be selectively included in a page message depending on the destination of the page message.

Claims

1. A method of communication, comprising:

receiving a message at a first node to setup communication between the first node and a second node, wherein the first node comprises a mobility management entity, wherein the message indicates a type of the second node, and the type comprises an eNodeB, a home eNodeB, or a home eNodeB gateway; and

determining, based on the indicated type, whether to include an allowed closed subscriber group list in a page message destined for the second node, wherein the determination comprises not including the allowed closed subscriber group list in the page message if the second node is a home eNodeB.

2. The method of claim 1, wherein the determination comprises including the allowed closed subscriber group list in the page message if the second node is a home eNodeB gateway.

3. The method of claim 1, wherein the message comprises an S1 protocol setup message that includes an indication of the type.

4. The method of claim 1, wherein the message comprises configuration update information.

5. The method of claim 1, further comprising:

receiving a page request message;

determining that the page message is to be sent to the second node based on the page request message; and

sending the page message to the second node.

6. An apparatus for communication, comprising:

a communication controller configured to receive a message at a first node to setup communication between the first node and a second node, wherein the first node comprises a mobility management entity, wherein the message indicates a type of the second node, and the type comprises an eNodeB, a home eNodeB, or a home eNodeB gateway; and

a paging controller configured to determine, based on the indicated type, whether to include an allowed closed subscriber group list in a page message destined for the second node, wherein the determination comprises not including the allowed closed subscriber group list in the page message if the second node is a home eNodeB.

7. The apparatus of claim 6, wherein the determination comprises including the allowed closed subscriber group list in the page message if the second node is a home eNodeB gateway.

8. An apparatus for communication, comprising:

means for receiving a message at a first node to setup communication between the first node and a second node, wherein the first node comprises a mobility management entity, wherein the message indicates a type of the second node, and the type comprises an eNodeB, a home eNodeB, or a home eNodeB gateway; and

means for determining, based on the indicated type, whether to include an allowed closed subscriber group list in a page message destined for the second node, wherein the determination comprises not including the allowed closed subscriber group list in the page message if the second node is a home eNodeB.

9. The apparatus of claim 8, wherein the determination comprises including the allowed closed subscriber group list in the page message if the second node is a home eNodeB gateway.

10. A computer-program product, comprising:

a non-transitory computer-readable medium comprising code for causing a computer to;

receive a message at a first node to setup communication between the first node and a second node, wherein the first node comprises a mobility management entity, wherein the message indicates a type of the second node, and the type comprises an eNodeB, a home eNodeB, or a home eNodeB gateway; and

determine, based on the indicated type, whether to include an allowed closed subscriber group list in a page message destined for the second node, wherein the determination comprises not including the allowed closed subscriber group list in the page message if the second node is a home eNodeB.

11. The computer-program product of claim 10, wherein the determination comprises including the allowed closed subscriber group list in the page message if the second node is a home eNodeB gateway.
