摘要： LTE-WLAN aggregation (LWA) at the radio access network level promises significant gain in system capacity and user quality of experience (QoE). In order to support QoS over LWA, there is a need to develop mechanisms to ensure that the access category (AC) classification chosen by a wireless device (AP in the case of downlink, and UE in case of uplink) is consistent with the QoS requirements of the EPS bearer/DRB and/or subscriber profile to which the traffic belongs. The cellular LTE network can provision QoS for both downlink and uplink data flows that are transferred using LWA access.

摘要： LWA (LTE/WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant user perceived throughput (UPT) improvement. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can dispatch the PDU either delivered over LTE link or WLAN link. The UPT improvement depends on how the eNB dispatches the PDU over LTE link or WLAN link. In one novel aspect, the eNB can acquire channel information, load information, and throughput estimation regarding with WLAN link and LTE link. As a result, the eNB can optimize UPT and LWA PDU dispatching algorithm.

摘要： Methods for LTE-WLAN interworking control and management are proposed. In one novel aspect, a mobile termination (MT) can use an AT command to report radio access network (RAN) assistance parameters of the current serving cell. A terminal equipment (TE) can use the AT command to query the specific RAN assistance parameters and the threshold value provided by the network for making LTE-WLAN interworking decisions. If reporting is enabled by TE, then an unsolicited result code (URC) is sent from MT to TE whenever changes in the current RAN assistance parameters occur.

摘要： LWA (LTE-WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant capacity and quality of experience (QoE) improvements. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can schedule the PDU either translated over LTE link or WLAN link. The eNB can acquire packet delay information regarding the WLAN link or obtain PDCP layer performance feedback from the UE. As a result, the eNB can adjust PDCP parameter setting and LWA scheduling accordingly.

摘要： Apparatus and methods are provided for LWA PDU routing. In one novel aspect, LTE PDU packets are routed through a WLAN AP to a UE by encapsulation of the data packets. An adaption layer encapsulate the whole packet as an Ethernet frame by appending the Ethernet MAC header to the payload. In other embodiments, the adaption layer encapsulates LTE PDU as GRE packet, configures VLAN for WLAN AP. In another novel aspect, the LTE PDU is identified by at least one of methods comprising the EtherType value, the source address, the GRE header, and the GTP header. In another embodiment, the default path is always used for LWA routing. In yet another novel aspect, the LTE PDU is forwarded by the MAC address, by the GRE tunnel configuration, or by the GTP tunnel configuration.
