System and method for seamless mobility in a network environment
In one example, an apparatus is provided that includes a processor configured to receive, in a first wireless network, an identifier of a base station in a second wireless network, and to determine an identity of a first device in the second wireless network. The apparatus is configured to transmit the identifier of the base station to the second wireless network.
1. An access gateway, comprising:
a processor configured to receive, in a wireless local area network, an identifier of a base station in a cellular network, wherein
the access gateway is configured to contact a first device in the cellular network via a tunnel, to receive an identity of a second device in the cellular network, and to establish a tunnel with the second device,
the access gateway is configured to transmit, using a protocol based on S1 Application Protocol (S1-AP) and a tunnel, the identifier of the base station to the cellular network, and to receive, using the tunnel, a first indication whether a handover from the wireless local area network to the cellular network is accepted, the first indication including a RACH preamble, and
the access gateway is configured to transmit a second indication in the wireless local area network that the handover is accepted.
2. The access gateway of claim 1 , wherein the processor is configured to determine an identity of the first device based at least in part on a location of a device in the wireless local area network.
3. The access gateway of claim 1 , wherein the processor is configured to determine an identity of the first device based at least in part on mapping information in a database.
4. The access gateway of claim 1 , wherein the access gateway is configured to transmit to the first device a Quality of Service (QoS) parameter of a session in the wireless local area network.
5. The access gateway of claim 1 , wherein the access gateway is configured to stop a transmission of data in the wireless local area network after transmitting the second indication.
6. The access gateway of claim 1 , wherein the second indication is an 802.11 MAC message.
7. The access gateway of claim 6 , wherein the 802.11 MAC message includes a frame control field in which the type is set to 01, and the subtype is set to 0010.
8. A non-transitory computer readable medium embedded with a computer executable program including instructions that, when executed by a processor, cause the processor to perform a method comprising:
receiving, in a wireless local area network, an identifier of a base station in a cellular network;
contacting a first device in the cellular network via a tunnel;
receiving an identity of a second device in the cellular network;
establishing a tunnel with the second device;
transmitting, using a protocol based on S1 Application Protocol (S1-AP) and a tunnel, the identifier of the base station to the cellular network;
receiving, using the tunnel, a first indication whether a handover from the wireless local area network to the cellular network is accepted, the first indication including a RACH preamble; and
transmitting a second indication in the wireless local area network that the handover is accepted.
9. The non-transitory computer readable medium of claim 8 , the method further comprising:
determining an identity of the first device based at least in part on a location of a device in the wireless local area network.
10. The non-transitory computer readable medium of claim 8 , the method further comprising:
determining an identity of the first device based at least in part on mapping information in a database.
11. The non-transitory computer readable medium of claim 8 , the method further comprising:
transmitting to the first device a Quality of Service (QoS) parameter of a session in the wireless local area network.
12. The non-transitory computer readable medium of claim 8 , the method further comprising:
stopping a transmission of data in the wireless local area network after the transmitting the second indication.
13. The computer readable medium of claim 8 , wherein the second indication is an 802.11 MAC message.
14. The computer readable medium of claim 13 , wherein the 802.11 MAC message includes a frame control field in which the type is set to 01, and the subtype is set to 0010.
15. A method, comprising:
receiving, in a wireless local area network, an identifier of a base station in a cellular network;
contacting a first device in the cellular network via a tunnel;
receiving an identity of a second device in the cellular network;
establishing a tunnel with the second device;
transmitting, using a protocol based on S1 Application Protocol (S1-AP) and a tunnel, the identifier of the base station to the cellular network;
receiving, using the tunnel, a first indication whether a handover from the wireless local area network to the cellular network is accepted, the first indication including a RACH preamble; and
transmitting a second indication in the wireless local area network that the handover is accepted.
16. The method of claim 15 , further comprising:
determining an identity of the first device based at least in part on a location of a device in the wireless local area network.
17. The method of claim 15 , further comprising:
determining an identity of the first device based at least in part on mapping information in a database.
18. The method of claim 15 , further comprising:
transmitting to the first device a Quality of Service (QoS) parameter of a session in the wireless local area network.
19. The method of claim 15 , further comprising:
stopping a transmission of data in the wireless local area network after the transmitting the second indication.
20. The method of claim 15 , wherein the first device is a database server or a mobility management entity.
21. The method of claim 15 , further comprising:
transmitting to the first device using an LTE_WLAN Handover (LWH) interface.
22. The method of claim 15 , wherein the second indication is an 802.11 MAC message including a frame control field in which the type is set to 01, and the subtype is set to 0010.
