Abstract
One or more nodes in a network provide access control for an in-bound handover of an access terminal to a closed subscriber group. For example, at least one of a source access point, a network node, or a target access point may determine whether handover is allowed based on whether a closed subscriber group identifier of the target access point is listed in closed subscriber group subscription information for the access terminal.
Claims38
A method of communication, comprising:
- establishing a connection for an access terminal at a first access point;
- receiving closed subscriber group subscription information for the access terminal at the first access point via a handover restriction list information element, wherein the closed subscriber group subscription information identifies at least one closed subscriber group at which the access terminal is allowed access;
- and
- determining, at the first access point, whether an identifier for a second access point is included in the received closed subscriber group information, wherein the determination at the first access point is triggered by a measurement report from the access terminal.
1 more element
An apparatus for communication, comprising:
- a communication controller configured to establish a connection for an access terminal at a first access point, and further configured to receive closed subscriber group subscription information for the access terminal at the first access point via a handover restriction list information element, wherein the closed subscriber group subscription information identifies at least one closed subscriber group at which the access terminal is allowed access;
- and
- a handover controller configured to determine, at the first access point, whether an identifier for a second access point is included in the received closed subscriber group information, wherein the determination at the first access point is triggered by a measurement report from the access terminal.
An apparatus for communication, comprising:
- means for establishing a connection for an access terminal at a first access point;
- means for receiving closed subscriber group subscription information for the access terminal at the first access point via a handover restriction list information element, wherein the closed subscriber group subscription information identifies at least one closed subscriber group at which the access terminal is allowed access;
- and
- means for determining, at the first access point, whether an identifier for a second access point is included in the received closed subscriber group information, wherein the determination at the first access point is triggered by a measurement report from the access terminal.
1 more element
A computer-program product, comprising:
- a non-transitory computer-readable medium comprising code for causing a computer to:
- establish a connection for an access terminal at a first access point;
- receive closed subscriber group subscription information for the access terminal at the first access point via a handover restriction list information element, wherein the closed subscriber group subscription information identifies at least one closed subscriber group at which the access terminal is allowed access;
- and
- determine, at the first access point, whether an identifier for a second access point is included in the received closed subscriber group information, wherein the determination at the first access point is triggered by a measurement report from the access terminal.
2 more elements
A method of communication, comprising:
- receiving a handover request message at a target access point from a source access point, wherein the handover request message comprises closed subscriber group subscription information in a handover restriction list information element for an access terminal, wherein the closed subscriber group subscription information received from the source access point comprises an identifier for at least one closed subscriber group at which the access terminal is allowed access;
- determining whether to allow the access terminal to be handed-over to the target access point in response to the handover request message, wherein the determination is based on the closed subscriber group subscription information;
- and
- sending, from the target access point, a path switch request message to a network node when the access terminal is to be handed-over to the target access point.
1 more element
An apparatus for communication, comprising:
- a communication controller configured to receive a handover request message at a target access point from a source access point, wherein the handover request message comprises closed subscriber group subscription information in a handover restriction list information element for an access terminal, wherein the closed subscriber group subscription information received from the source access point comprises an identifier for at least one closed subscriber group at which the access terminal is allowed access;
- a handover controller configured to determine whether to allow the access terminal to be handed-over to the target access point in response to the handover request message, wherein the determination is based on the closed subscriber group subscription information;
- and
- a transmitter to send, from the target access point, a path switch request message to a network node when the access terminal is to be handed-over to the target access point.
1 more element
An apparatus for communication, comprising:
- means for receiving a handover request message at a target access point from a source access point, wherein the handover request message comprises closed subscriber group subscription information in a handover restriction list information element for an access terminal, wherein the closed subscriber group subscription information received from the source access point comprises an identifier for at least one closed subscriber group at which the access terminal is allowed access;
- means for determining whether to allow the access terminal to be handed-over to the target access point in response to the handover request message, wherein the determination is based on the closed subscriber group subscription information;
- and
- means for sending, from the target access point, a path switch request message to a network node when the access terminal is to be handed-over to the target access point.
1 more element
A computer-program product, comprising:
- a non-transitory computer-readable medium comprising code for causing a computer to:
- receive a handover request message at a target access point from a source access point, wherein the handover request message comprises closed subscriber group subscription information in a handover restriction list information element for an access terminal, wherein the closed subscriber group subscription information received from the source access point comprises an identifier for at least one closed subscriber group at which the access terminal is allowed access;
- determine whether to allow the access terminal to be handed-over to the target access point in response to the handover request message, wherein the determination is based on the closed subscriber group subscription information;
- and
- send, from the target access point, a path switch request message to a network node when the access terminal is to be handed-over to the target access point.
