Claim of US Patent No. 9,301,295

1. A method of operating a wireless communication network comprising:
in a network control system, receiving a request for at least one of a data or media session with a wireless communication
device, and in response, determining if the wireless communication device is idle and determining if a source base station
that currently serves the wireless communication device is configured to support the at least one of the data or media session;

in the network control system, if the wireless communication device is idle and the source base station is not capable of
supporting the media session, then identifying a target base station that is configured to support the media session and transferring
a first redirect message for delivery to the wireless communication device through the source base station and transferring
a second redirect message for delivery to the target base station, wherein the first redirect message and the second redirect
message have session information for the media session;

in the network control system, if the wireless communication device is not idle and the source base station is not capable
of supporting the data session, then identifying a target base station that is configured to support the data session and
transferring a first redirect message for delivery to the wireless communication device through the source base station and
transferring a second redirect message for delivery to the target base station, wherein the first redirect message and the
second redirect message have session information for the data session;

in the source base station, transferring the first redirect message to the wireless communication device;
in the target base station, receiving an acceptance of the at least one of the data or media session from the wireless communication
device and exchanging data or media for the at least one of the data or media session responsive to the acceptance.
