Abstract
Systems and method are provided that allow a mobile device to communicate over multiple access technologies at the same time, including a cellular access technology, such as LTE, and via an untrusted WLAN access. The untrusted access is initiated via internet key exchange. The mobile device uses the same IP address over both access technologies.
Claims21
A gateway comprising:
- interfaces for communicating with mobile devices, including a first mobile device, via a wireless cellular access technology and a wireless non-cellular access technology;
- and
- a processor for executing software modules stored in a memory device;
- the gateway configured to:
- provide, the first mobile device, a single Internet Protocol (IP) address for use to communicate with a server associated with an access point name (APN) simultaneously over the cellular wireless access technology and the non-cellular wireless access technology, wherein the IP address is allocated by the gateway when the mobile device attaches to the gateway to communicate using the wireless cellular access technology and the gateway sends an acknowledgment to an enhanched packet data gateway (ePDG) confirming allocation of the same IP address for the mobile device when the mobile device attaches to the gateway to communicate using the wireless non-cellular access technology,
- receive and send IP flow information for allowing simultaneous access with the wireless cellular access technology and the wireless non-cellular access technology,
- provide to the first mobile device a single traffic flow template (TFT), applicable for the wireless cellular access technology and the wireless non-cellular access technology, to allow the first mobile device to select the wireless cellular access technology for providing a first data flow associated with a first application and to select the wireless non-cellular access technology for providing a second data flow associated with a second application,
- provide simultaneous data flows to the first mobile device via the cellular access technology and the non-cellular access technology, wherein the communication with the first mobile device for attachment to the gateway for the non-cellular access technology is performed via the enhanced packet data gateway (ePDG), and
- send a message to a server in communication with the gateway, indicating that a particular data flow is associated with either the wireless cellular access technology or the wireless non-cellular access technology.

A method comprising:
- communicating with a mobile device, by a gateway, to provide a single Internet Protocol (IP) address for use to communicate with a server associated with an access point name (APN) simultaneously over a wireless cellular access technology and a wireless non-cellular access technology, wherein the IP address is allocated by the gateway when the mobile device attaches to the gateway to communicate using the wireless cellular access technology and the gateway sends an acknowledgment to an enhanced packet data gateway (ePDG) confirming allocation of the same IP address for the mobile device when the mobile device attaches to the gateway to communicate using the wireless non-cellular access technology,
- receiving and sending, by the gateway, IP flow information for allowing simultaneous access with the wireless cellular access technology and the wireless non-cellular access technology,
- providing, by the gateway to the first mobile device, a single traffic flow template (TFT), applicable for the wireless cellular access technology and the wireless non-cellular access technology, to allow the first mobile device to select the wireless cellular access technology for providing a first data flow associated with a first application and to select the wireless non-cellular access technology for providing a second data flow associated with a second application,
- providing, by the gateway, simultaneous flows to the mobile device via the cellular access technology and the non-cellular access technology, and
- sending, by the gateway, a message to a server in communication with the gateway, indicating that a particular data flow is associated with either the wireless cellular access technology or the wireless non-cellular access technology,
- wherein the communication with the mobile device for attachment to the gateway for the non-cellular access technology is performed via the enhanced packet data gateway (ePDG).

A user equipment comprising:
- a processor for executing instructions, stored in a memory device, operable to cause the user equipment to:
- communicate, using a single Internet Protocol (IP) address, with a server associated with an access point name (APN) simultaneously via a cellular access technology and an untrusted non-cellular access technology, wherein the IP address is obtained by the user equipment from the gateway when the mobile device attaches to the gateway to communicate using the wireless cellular access technology and wherein the user equipment requests the same IP address from the gateway when the user equipment attaches to the gateway to communicate using the wireless non-cellular access technology, wherein the gateway is to send an acknowledgement to an enhanced packet data gateway (ePDG) confirming allocation of the same IP address for the mobile device when the user equipment attaches to the gateway to communicate using the wireless non-cellular access technology,
- select, using a single traffic flow template (TFT), applicable for the cellular access technology and the untrusted non-cellular access technology, received from the gateway, the wireless cellular access technology for receiving a first data flow associated with a first application,
- select, using the TFT, the wireless non-cellular access technology for providing a second data flow associated with a second application, and
- receive the first data flow and the second data flow simultaneously via the cellular access technology and the non-cellular access technology,
- wherein the user equipment is configured to attach to the gateway for the non-cellular access technology via the ePDG.
