Network-instructed handover from WLAN to another radio access network

A wireless Local Access Network WLAN, access node comprising:

• a processor;
• and memory containing instructions executable by the processor whereby the WLAN access node is operative to:
• decide that a handover of a wireless device from a WLAN to another radio access network of a different radio access technology is to be performed;
• and
• transmit a handover instruction to the wireless device that instructs the wireless device to perform a handover from the WLAN to a radio access network of a different radio access technology, wherein the different radio access technology is a 3rd Generation Partnership Project, 3GPP, radio access technology, wherein the handover instruction comprises information that indicates whether the handover is a full handover of all communication sessions or a selective handover of one or more but less than all communication sessions, and wherein the WLAN can perform both full handovers and selective handovers.

A method of operation of a wireless device, comprising:

• communicating with a Wireless Local Access Network, WLAN, access node;
• receiving a handover instruction from the WLAN access node to perform a handover from a WLAN to another radio access network of a different radio access technology, the handover instruction being decided by the WLAN access node;
• and
• performing the handover in response to receiving the handover instruction, wherein the different radio access technology is a 3rd Generation Partnership Project, 3GPP, radio access technology;
• wherein the handover instruction comprises information that indicates whether the handover is a full handover of all communication sessions or a selective handover of one or more but less than all communication sessions, and wherein the wireless device can perform both full handovers and selective handovers.

A wireless device comprising:

• a transceiver;
• a processor;
• and
• memory containing instructions executable by the processor whereby the wireless device is operative to:
• communicate with a Wireless Local Access Network, WLAN, access node of a WLAN via the transceiver;
• receive, via the transceiver, a handover instruction from the WLAN access node to perform a handover from the WLAN to another radio access network of a different radio access technology, the handover instruction being decided by the WLAN access node;
• and
• perform the handover in response to receiving the handover instruction, wherein the different radio access technology is a 3rd Generation Partnership Project, 3GPP, radio access technology, wherein the handover instruction comprises information that indicates whether the handover is a full handover of all communication sessions or a selective handover of one or more but less than all communication sessions, and wherein the wireless device can perform both full handovers and selective handovers.
