Embodiment Construction

[0026] The following descriptions are preferred embodiments for implementing the present invention, and some embodiments are illustrated by the accompanying drawings.

[0027] Figure 1A is a system diagram of a wireless network 100 with LWA according to an embodiment of the present invention. The wireless network 100 includes a serving gateway S-GW 101 connected to the operator, which can filter and transmit (filter-and-forward) or transmit data packets to the LTE base station; a packet data network gateway PDN-GW 102 connected to the Internet, which can perform Control plane establishment (such as QoS mapping) and user plane packet routing (routing); base station eNB 103 can provide LTE cellular wireless access through E-URTRAN; access point AP 104 can provide Wi-Fi wireless access through WLAN; and user equipment UE 105 .

[0028]Both LTE and WLAN standards have developed mechanisms to provide QoS. In LTE, it is basically the responsibility of the network to ensure QoS, ...

Abstract

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 LE network can provision QoS for both downlink and uplink data flows that are transferred using LWA access.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application No. 62 / 162,277, filed May 15, 2015, entitled "QoS Provisioning for LTE-WLAN Aggregation," and which application for reference. technical field [0003] The present invention relates to wireless communication, and in particular to Quality of Service (QoS) provisioning for Long Term Evolution (LTE)-Wireless Local Area Network (WLAN) aggregation. Background technique [0004] Mobile data applications have grown exponentially in recent years. Due to its simplified network architecture, the LTE system can provide high peak data rates, low latency, increased system capacity, and lower operating costs. In the LTE system, the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) includes multiple base stations, such as evolved Node-B (evolved Node-B, eNB), which communicate with multiple mobile stations, ...
