Abstract

Local breakout mechanisms can be performed by a femto access point (FAP) to facilitate efficient utilization of backhaul and/or macro networks. In particular, a slave Gateway GPRS Support Node (GGSN) can be integrated within the FAP to directly route the incoming traffic from a user equipment (UE) at the FAP. In one example, Internet bound traffic can be directly routed to the Internet, without employing macro network resources. Further, the system can avoid hairpinning by routing traffic between the UE and a home Local Area Network (LAN) by a anchoring a call or a session in the slave GGSN and facilitate integration of UEs with home applications by employing a UE Digital Home Agent. In addition, the FAP can perform UE-to-UE CS media breakout to facilitate communication between UEs attached to the FAP, without routing the traffic through the core macro network.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

determining routing data, which represents a first routing path for routing of data associated with a first device through a first network device in communication with the system, based on policy data and device data stored in a data store, wherein the policy data represents policies for the system and the device data represents information for the first device and a second device in communication with the system;

performing a local breakout for the data associated with the first device based on the policy data and the device data stored in the data store; and

in response to receiving instruction data associated with an instruction to override the local breakout, disabling a breakout functionality associated with the system, and updating the policy data and the routing data to represent a second routing path for the routing of the data through a second network device in communication with the system.

2. The system of claim 1, wherein the determining the routing data comprises analyzing at least a portion of the data.

3. The system of claim 1, wherein the determining the routing data comprises analyzing user data indicative of user preferences for a user identity associated with the first device.

4. The system of claim 1, wherein the receiving the instruction data comprises receiving timing data associated with the disabling of the breakout functionality.

5. The system of claim 1, wherein the disabling the breakout functionality comprises disabling the breakout functionality for a defined period of time.

6. The system of claim 1, wherein the updating the routing data comprises modifying a portion of the data based on the policy data and the device data.

7. The system of claim 1, wherein the updating the routing data comprises updating the routing data based on network congestion data associated with a second network device.

8. The system of claim 1, wherein the operations further comprise:

receiving, from the data store, the policy data via the first network device or a third network device.

9. The system of claim 1, wherein the operations further comprise:

based on the second routing path, routing the data to a second network device.

10. A method, comprising:

determining, by a system comprising a processor, routing data, which represents a first path for routing a data packet associated with a first user device via a first network device in communication with the system, based on policy data that represents policies for a local breakout associated with the system, and device data that represents information for the first user device and a second user device in communication with the system;

performing, by the system, the local breakout for the data packet based on the policy data and the device data; and

in response to receiving command data associated with a command to override the local breakout, disabling, by the system, a local breakout functionality associated with the system, and updating the policy data and the routing data to represent a second path for the routing of the data packet via a second network device in communication with the system.

11. The method of claim 10, wherein the determining the routing data comprises analyzing a header associated with the data packet.

12. The method of claim 10, wherein the determining the routing data comprises analyzing data packet information associated with the data packet.

13. The method of claim 10, wherein the disabling the local breakout functionality comprises disabling the local breakout functionality for a defined time interval.

16. The method of claim 10, further comprising:

based on the second path, routing, by the system, the data packet to a third network device.

17. A non-transitory machine-readable storage medium comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

determining routing data, which represents a first route for routing of data traffic associated with a first user equipment through a first network device, based on policy data and device data, wherein the policy data and the device data are stored in a data store, and wherein the policy data represents local breakout policies for a local breakout and the device data represents information for the first equipment and a second user equipment;
