Claim of US Patent No. 10,560,940

1. A method comprising:assigning one of a plurality of available access channels to a service flow between a communication device and a core network, wherein the plurality of available access channels have at least one of sufficient bandwidth or acceptable latency to accommodate the service flow, and wherein the plurality of available access channels use a plurality of connectivity paths supported by a plurality of access technologies;
modifying, based on monitoring at least one of network conditions or performance of the service flow on the one of the plurality of available access channels, one of the plurality of connectivity paths that supports the one of the plurality of available access channels;
modifying criteria for modifying the one of the plurality of connectivity paths for a predetermined time interval in response to modifying the one of the plurality of connectivity paths; and
modifying the one of the plurality of connectivity paths during the predetermined time interval in response to the modified criteria indicating that a previous modification of the one of the plurality of connectivity paths did not improve a quality-of-experience for the communication device.
