A generic access network infrastructure controller entity (400) including
a controller communicably coupled to a signal transceiver. The controller
is configured to send a handover failure message to a dual-mode wireless
communication subscriber terminal in response to a handover request
received at the transceiver wherein the handover failure message
indicates that handover from the unlicensed mobile access network to the
radio access network is currently not possible. The entity may also send
a time value to the dual-mode wireless communication subscriber terminal
in response to the handover request, wherein the time value indicate when
the dual-mode wireless communication subscriber terminal may re-send the
handover request.
