“…It depends on optimizer platforms, whether 5 minutes is the total duration of the video and the mediation platform uses justin-time delivery, or video is longer, but a higher download speed enables to get the whole content at the playbacks beginning. 45 ms Now we need to define the parameters for calculating blocking probability in case of legacy LTE network, using formulas (12), (13), (14) and (15). Based on the assumed network topology: Fig.…”

-In order to effectively deliver traffic from different applications, providing end-to-end Quality of Service (QoS) is critical in Long Term Evolution (LTE) networks. Mobility requires special handling of QoS enforcement rules and methods. The LTE QoS Signaling (LQSIG) protocol presented in this paper will allow ensuring resource reservation before using a data path. Operation of the proposed protocol in different mobility scenarios is also explained. The key features of the protocol include LTE QoS model mapping to QSPEC (QoS Specification) objects used in reservation and interworking with mobility protocols in the LTE protocol stack, especially with Radio Resource Control (RRC). The basics of an analytical model are proposed in order to determine the blocking probability at the bottlenecks of LTE network. A performance analysis of LQSIG describes its properties compared to legacy LTE networks.
