METHODS AND SYSTEM FOR RESOURCE ALLOCATION IN AN INTEGRATED 3G-WLAN MOBILE WIRELESS MULTIMEDIA NETWORK

摘要

The present invention relates to methods and system for efficient resource allocation in wireless local area network (WLAN) and an integrated 3G-WLAN wireless network. The system consists of a two hop wireless network where some WLAN mobile devices communicate with WLAN access point over the air-interface and the WLAN AP in turn communicates with the 3G base station over the air-interface. The system embodies various adaptive scheduling methods that are executed at the access points of WLAN and 3G networks. Some of these methods control the polling sequence for different multimedia flows at the access point of a wireless local area network. Some of these methods also control the manner in which time slots are allocated to multimedia flows in a 3G network. Some of these flows are for mobile devices connected to 3G network while some other flows are aggregate flows for devices connected to a mobile wireless local area network. These satisfy QoS requirements of diverse type of applications, provide different fairness criterion to allocate time to different mobile devices in 3G-WLAN network and allow a network operator to offer different types of service level agreements.
