  • towards elastic application oriented Bearer Management for enhancing qoe in lte networks
    Wireless Communications and Networking Conference, 2016
    Co-Authors: Tarik Taleb, Konstantinos Samdanis, Adlen Ksentini
    Abstract:

    This paper introduces the concept of elastic Bearer in Evolved Packet System (EPS), which allows, on one hand, the users to enhance on-demand the performance of certain applications and on the other hand, it permits the network to efficiently manage the resource allocation considering the application type. In particular, the paper introduces a set of mechanisms to trigger and support Bearer elasticity in EPS based on Quality of Experience (QoE) perceived by users or based on feedback from Radio Access Network (RAN). Bearer elasticity can be attained through potential Packet Data Network/Serving Gateway (PDN/S-GW) relocation to eventually improve QoE within and beyond the mobile network operator premises. The paper also introduces a set of methods to identify and cope with a “storm” of requests for particular applications at densely populated areas.

  • Virtual Bearer Management for efficient MTC radio and backhaul sharing in LTE networks
    IEEE International Symposium on Personal Indoor and Mobile Radio Communications PIMRC, 2013
    Co-Authors: Konstantinos Samdanis, Mohammad Istiak Hossain, Andreas Kunz, Tarik Taleb
    Abstract:

    Abstract—The increasing adoption of Machine Type Com- munication (MTC) applications using the Long Term Evolution (LTE) brings new challenges for the traditional Bearer allocation and network Management. MTC devices are high in number, each requiring an individual Bearer for a short data transmission; an inefficient process considering the signaling and Management effort to the duration of the actual Bearer use. This paper introduces the notion of a virtual Bearer that can be shared among a number of MTC devices with similar Quality of Service (QoS) characteristics. The virtual Bearer support at the MTC device side is based on the paradigm of Network Function Virtualization (NFV) and can migrate from one MTC device to another eliminating the need for individual device Bearer establishment for both the radio and backhaul. The use of virtual Bearers is enhanced by considering additionally MTC device-to- device (D2D) connectivity allowing devices without direct access to the network to use the virtual Bearer via other devices, which act as gateways. Gateway devices may also be re-located dynamically based on NFV principles. In this way, a finer control is achieved on prioritizing certain services and providing load balancing. Our simulation results demonstrate the benefits of our proposed scheme compared to conventional approaches wherein MTC devices use individual Bearers to send data in response to a trigger or according to a predetermined schedule

  • A moving cell Bearer Management architecture for LTE-Advanced system
    2015 17th International Conference on Advanced Communication Technology (ICACT), 2015
    Co-Authors: Yousun Hwang, Jaewook Shin
    Abstract:

    Mobile data traffic has been predicted to grow exponentially in the next several years due to recent increased penetration of mobile devices running a vast array of mobile applications. Moving cell is a concept to further evolve fixed small cell technology for the next generation wireless system which is solved the rapid increase of traffic. It provides a continuous connection to the mobile network and moves around its connection network along to the user. A moving cell in Long Term Evolution-Advanced (LTE-A) cellular network confers a flexibility to the system and allows for a more enhanced mobility Management, and supports heterogeneous radio access technologies simultaneously. It can establish the new Bearer type for heterogeneous radio access technologies and improve the quality of service for user and to provide high data rate, low delay, and low power consumption for user mobile equipment. In this paper, we propose a moving cell Bearer control mechanism and the architecture of moving cell supported by a LTE-A system for 5 Generation. The cellular network needs to establish a new type of the Evolved Packet System (EPS) Bearer for WiFi radio Bearer of the moving cell. We describe the entities of this architecture, the protocol stack and describe how user Bearers setup.

  • Application of SDL in radio Bearer Management
    Journal of Chongqing University of Posts and Telecommunications, 2005
    Co-Authors: Li Xiao-wen
    Abstract:

    In the 3rd generation mobile telecommunication protocols, owing to radio bears concept used, this not only makes 3G system more satisfy the requirement of traditional voice and future fast speed data service, but also makes it possible to provide various and colorful multi-media service. This paper uses the radio bear Management of TD-SCDMA UE side as an example to introduce the basic procedures of radio bear Managements and provide the approach to realize them with general development of C language under SDL development environment according to requirement of protocols.
