LTE Techniques in 4G Wireless System Using Protocol Stack
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
LTE, an acronym for Long-Term Evolution. 4G LTE is a standard for wireless broadband technology designed to support roaming Internet access via cell phones and handheld devices. Due to the requirements on high data rate and low latency for broadband wireless communication systems, LTE air-interface protocol stacks to be designed and implemented with high data processing efficiency. LTE user equipment (UE), this paper analyzes the main challenges in the link-layer protocol stack design and application, including the data handling efficiency, synchronic, flexibility and portability. Authentication service is one of the most essential services in LTE networks. A memory access optimization and lightweighted thread model are proposed to improve the data processing efficiency. QoS Proposal to overcome such as channel capacity, latency, delay, Jitter, Packet loss, large RTTs. Voice over LTE is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. VoIP support the necessary protocols and features required for VoIP streaming including the implementation of Real Time Protocol (RTP) and an IP stack. In this paper, we survey and compare LTE security for Mobile Access Border security (RAN-to-EPC/S1), Internet Border security (EPC-to-Internet/SGi) and Partner Border security (EPC-to-EPC / S8).
