This paper describes the design and implementation of MBS (multicast & broadcast service) server for mobile IPTV service in WiMAX networks. Based on interoperability requirements of WiMAX networks, the presented MBS server was implemented for mobile IPTV services and basically provides MBS service announcement and session management functions, dynamic MBS zone management, and MBS data transmission.
The main purpose of this paper is the functional design of BM-SC (Broadcast Multicast Service Centre) to support IPTV. BM-SC is newly defined by 3GPP/LTE to support delivering IMS (IP Multimedia Subsystem) over wireless broadband network. Delivering Mobile IPTV (Internet Protocol Television) over LTE (Long Term Evolution) network is requires more complex and more flexible functional operation. A functional...
As the interests of broadcasting services in mobile networks are increased, the research of convergence services of broadcasting and communication has become popular. To support broadcasting services in cellular network smoothly, WiBro support the multicast and broadcast service (MBS). MBS is transmission method that base stations belong to same MBS zone transmit the data to all users who request...
It's necessary to enhance the capacity of wireless access network to provide mobile IPTV service. In this paper MMR(Mobile Multi-hop Relay) system is introduced to increase the performance of mobile system based on IEEE 802.16m which introduced network coding technology to increase the performance of radio link. Radio link quality and mobile terminal throughput are analysed by simulation when RS(Relay...
Currently, the multimedia stream service provided by broadband wireless networks has emerged as an important technology and attracted much attention in the research of mobile IPTV which provide common content or program to multiple subscribers by using IP multicast service. Multicast and broadcast services (MBS) are described in the mobile WiMAX standard. The Qualnet network simulator is a more prevailing...
