Abstract

Embodiments of methods and systems for mobility in enterprise networks are presented. The methods and systems described herein provide a mobile wireless device with access to both an enterprise network and an external network by establishing a proxy connection between a gateway component of the enterprise network and a gateway component of the external network. Such embodiments may maintain the security of the enterprise network. Additionally, such embodiments may not require modification of the User Equipment (UE) or of components of the external network. Indeed, the methods and systems may operate transparently to both the UE and to components of the external network.

Claims (39)

1. A method for providing a wireless device with simultaneous access to an enterprise network and an external network, comprising:

establishing a proxy connection between a gateway device in the enterprise network and a gateway device in the external network as though the gateway device in the enterprise network is a component of the external network, transparent to the gateway device in the external network that the gateway device in the enterprise network is not an element of the external network;

receiving a communication request from the wireless device at the gateway device in the enterprise network;

determining whether the communication request requires a connection to the enterprise network or to the external network; and

facilitating communications between the wireless device and the external network through the proxy connection in response to a determination that the communication request requires a connection to the external network, the proxy connection transparent to the wireless device and the external network.

2. The method of claim 1 , wherein the wireless device is configured to operate according to a mobile data communications standard.

3. The method of claim 2 , wherein the mobile data communications standard is the Long Term Evolution (LTE) communications standard.

4. The method of claim 2 , wherein the wireless device is also configured to operate according to WiFi standards.

5. The method of claim 1 , wherein the gateway in the enterprise network is a Packet Data Network (PDN) Gateway (P-GW) device.

6. The method of claim 1 , wherein the gateway in the external network is a Packet Data Network (PDN) Gateway (P-GW) device.

7. The method of claim 6 , wherein the gateway in the enterprise network presents itself to the P-GW device in the external network as at least one of a Mobility Management Entity (MME) device or a Servicing Gateway (S-GW) device of the external network.

8. The method of claim 6 , wherein the gateway in the enterprise network connects to the P-GW device in the external network via a standard connection on at least one of interfaces S5 or S8.

9. The method of claim 1 , wherein the gateway in the external network is a Servicing Gateway (S-GW) device.

10. The method of claim 9 , wherein the gateway in the enterprise network presents itself to the S-GW device in the external network as a Home eNodeB Gateway (HeNB-GW) device of the external network.

11. The method of claim 9 , wherein the gateway in the enterprise network connects to the S-GW device in the external network via a connection on a standard S1-U interface.

12. The method of claim 1 , wherein the gateway in the external network is a Mobility Management Entity (MME) device.

13. The method of claim 12 , wherein the gateway in the enterprise network presents itself to the MME device in the external network as a Home eNodeB Gateway (HeNB-GW) device of the external network.

14. The method of claim 12 , wherein the gateway in the enterprise network connects to the S-GW device in the external network via a connection on a standard S1-MME interface.

15. The method of claim 1 , further comprising obtaining User Equipment (UE) configuration information for enabling the wireless device to communicate with the external network from a Home Subscriber Server (HSS) of the external network through a second proxy connection established between an HSS of the enterprise network and the HSS of the external network.

16. The method of claim 15 , wherein establishing the second proxy connection further comprises the HSS of the enterprise network connecting to the HSS of the external network on interface S6a.

17. The method of claim 1 , further comprising providing Quality of Service (QoS) services for connections between the wireless device and the external network via the proxy connection.

18. The method of claim 1 , further comprising terminating the proxy connection in response to a determination that the wireless device has terminated a connection with the enterprise network.

19. A tangible computer-readable storage medium having program instructions stored thereon that, upon execution by a processor, cause the processor to perform operations for providing a wireless device with simultaneous access to an enterprise network and an external network, comprising:

establishing a proxy connection between a gateway device in the enterprise network and a gateway device in the external network as though the gateway device in the enterprise network is a component of the external network, transparent to the gateway device in the external network that the gateway device in the enterprise network is not an element of the external network;

receiving a communication request from the wireless device at the gateway device in the enterprise network;

determining whether the communication request requires a connection to the enterprise network or to the external network; and

facilitating communications between the wireless device and the external network through the proxy connection in response to a determination that the communication request requires a connection to the external network, the proxy connection transparent to the wireless device and the external network.

20. A system for providing a wireless device with simultaneous access to an enterprise network and an external network, comprising:

a gateway device in the enterprise network configured to:

establish a proxy connection between the gateway device in the enterprise network and a gateway device in the external network as though the gateway device in the enterprise network is a component of the external network, transparent to the gateway device in the external network that the gateway device in the enterprise network is not an element of the external network;

receive a communication request from the wireless device at the gateway device in the enterprise network;

determine whether the communication request requires a connection to the enterprise network or to the external network; and

facilitate communications between the wireless device and the external network through the proxy connection in response to a determination that the communication request requires a connection to the external network, the proxy connection transparent to the wireless device and the external network.

21. A system, comprising:

a first interface for establishing a proxy connection with a gateway device in an external network, transparent to the gateway device that the first interface is not a component of the external network;

a second interface configured to receive a communication request from a wireless device in an enterprise network; and

a processor coupled to the first interface and to the second interface, the processor configured to:

determine whether the communication request requires a connection to the enterprise network or to the external network; and

facilitate communications between the wireless device and the external network through the proxy connection in response to a determination that the communication request requires a connection to the external network, the proxy connection transparent to the wireless device and the external network.
