Abstract
Systems and/or methods may be used to handle failure of a HeNB/HNB, a SeGW, or an edge component. For example, actions may be performed by the edge component when a HeNB, a CGW, or a SeGW fails. The actions that may be performed when a SeGW may fail may include tearing down an IPSec tunnel to a HeNB connected to the edge component, using S1-AP signaling, a signaling interface (e.g., a connection management interface (CMI), an X2 interface, and/or a Sxx interface to inform the HeNB of the failure, and/or the like. The actions that may be performed when a HeNB may fail may include using S1-AP signaling and/or a signaling interface (e.g., a CMI) to inform a mobility management entity (MME) of the failure, and/or the like.
Claims32
A method for handling a failure of a secure gateway (SeGW), the method comprising:
- establishing, with an edge component, a first connection to a first SeGW in a core network and a second connection to a home eNode-B (HeNB) in a local home network, the HeNB being connected to one or more components in the core network via the first SeGW and the edge component;
- determining, at the edge component, whether the first SeGW has failed;
- establishing, at the edge component, a third connection to a second SeGW in response to determining that the first SeGW has failed;
- and
- informing the HeNB that the first SeGW has failed to enable the HeNB to reconnect to the one or more components in the core network via the second SeGW and the edge component.
A method for handling a failure of a home node-B (HNB), the method comprising:
- establishing, with an edge component, a first connection to a secure gateway (SeGW) in a core network and a second connection to the HNB in a local home network, the HNB being connected to a mobility management entity (MME) in the core network via the SeGW and the edge component;
- determining, at the edge component, that the HNB has failed;
- and
- informing the MME in the core network via the edge component and the SeGW that the HNB has failed to enable the MME to remove information associated with the HNB that has failed.
An edge component for handling a failure of at least one of a secure gateway (SeGW) or a home node-B (HNB), the edge component comprising a processor configured to:
- establish, with the edge component, a first connection to the SeGW in a core network and a second connection to the HNB in a local home network, the HNB being connected to at least a mobility management entity (MME) in the core network via the SeGW and the edge component;
- determine whether at least one of the SeGW or HNB has failed;
- in response to determining that the SeGW has failed:
- establish, at the edge component, a third connection to another SeGW;
- inform the HNB that the SeGW has failed to enable the HNB to reconnect to the MME in the core network via the another SeGW and the edge component;
- and
- in response to determining that the HNB has failed:
- inform the MME in the core network via the edge component and the SeGW that the HNB has failed to enable the MME to remove information associated with the HNB that has failed.
