Dynamic Algorithms for WLAN-Cellular Performance Estimation, Access Selection, and Traffic Offload

A method comprising:

• obtaining an association status of a user equipment (UE) in a wireless network for each radio access link, wherein the UE is capable of connecting to both a first radio access link and a second radio access link;
• determining a quality of service (QoS) requirement for a traffic flow of the UE;
• and
• estimating and comparing throughputs of the first radio access link and the second radio access link based on the association status and the QoS requirement;
• and
• determining traffic offloading and traffic steering between the first and the second radio access link based on the obtained estimation and throughput comparison.

A user equipment (UE) comprising:

• a first transceiver that transmits and receives radio signals via a first radio access link;
• a second transceiver that transmits and receives radio signals via a second radio access link;
• a connection status module that determines corresponding connection status for each radio access link;
• and
• a radio access link throughput module that determines corresponding radio access throughput for at least one of the first and the second radio access link based on the corresponding connection status, wherein the radio access throughput is measured if the UE is connected with corresponding radio access link, otherwise, the radio access throughput is estimated.
