This article highlights QoS frameworks and features of OFDMA-based 4G technologies - IEEE802.16e, IEEE 802.16m, and LTE - to support various applications' QoS requirements to be future-proof to deliver the incumbent as well as emerging mobile Internet applications.Abstract:
A quality of service framework is a fundamental component of a 4G broadband wireless network for satisfactory service delivery of evolving Internet applications to end users, and managing the network resources. Today's popular mobile Internet applications, such as voice, gaming, streaming, and social networking services, have diverse traffic characteristics and, consequently, different QoS requirements. A rather flexible QoS framework is highly desirable to be future-proof to deliver the incumbent as well as emerging mobile Internet applications. This article highlights QoS frameworks and features of OFDMA-based 4G technologies - IEEE 802.16e, IEEE 802.16m, and LTE - to support various applications' QoS requirements. A few advanced QoS features such as new scheduling service (i.e., aGP), quick access, delayed bandwidth request, and priority controlled access in IEEE 802.16m are explained in detail. A brief comparison of the QoS framework of the aforementioned technologies is also provided.read more

Call admission control based on adaptive bandwidth allocation for wireless networks
TL;DR: In this article, the authors proposed an efficient call admission control algorithm that relies on adaptive multi-level bandwidth-allocation scheme for non-real-time calls, which allows reduction of the call dropping probability, along with an increase in the bandwidth utilization.

Policy and charging control architecture
TL;DR: In this article, the authors propose an approach for generating policy and charging rules to control IP flows across a packet switched network, which consists of a first interface for coupling to an application function and a second interface to coupling to a policy and enforcement function implemented at a node through which said IP flows pass.
