OPPORTUNISTIC RADIO ACCESS TECHNOLOGY SELECTION AND AGGREGATION

摘要

Systems, methods, and instrumentalities are provided for managing multiple radio access technology (RAT) interfaces to enable opportunistic RAT selection and aggregation for sending data traffic over the multiple RAT interfaces. A system for selecting a RAT may include an Internet Protocol (IP) layer and RAT protocol stacks residing below the IP layer. An opportunistic multiple media access control aggregation (OMMA) layer may reside between the IP layer and the RAT protocol stacks. The OMMA layer may include an OMMA scheduler that may distribute incoming IP data packets among the RAT protocol stacks. An OMMA controller may communicate a control parameter to the OMMA scheduler for selecting a RAT protocol stack for distributing an incoming IP data packet. A wireless transmit/receive unit RAT capability database may store RAT capability information. A policy database may store a policy for distributing the IP data packets among the RAT protocol stacks.
