Roaming across heterogeneous wireless networks such as wireless wide area network (WWAN) and wireless local area network (WLAN) poses considerable challenges, as it is usually difficult to maintain the existing connections and guarantee the necessary end-to-end quality-of-service (QoS). This paper proposes a novel end-to-end QoS guaranteed seamless handover scheme, which can maintain the connections...
As the existence of diverse network technologies, QoS signaling is needed to guarantee the end-to-end QoS for users in complex network environment. Compared with the previous QoS signaling with resource reservation, NSIS (next steps in signaling) proposed by IETF is better in flexibility and scalability. This paper proposes a new mobility-aware scheme for QoS NSLP (NSIS signaling layer protocol) in...
Call admission control is an essential approach for traffic control and QoS provisioning. Compared with the single network, it is quite complicate for multi-service heterogeneous wireless networks. In this paper, a hierarchical joint call admission control HJCAC is proposed. The framework of the scheme, new introduced messages format and service access procedure is also designed in this paper. Simulation...
