Research On Application And Algorithm Of The Mobile State Of LTE-A

With the continuous development of the communication, mobile network has evolved from2G,3G and it has become focus on LIE and LTE-A network which is so called the4G network. Though the constant development and improvement of the network, the requirement of the network users is increasing at the same time. In this thesis, the author’s main purpose is to improve the quality of service of the LTE-A network, so as to achieve optimal performance of the network. LTE-A aimed to provide high throughput of the data traffic and high quality of service. However, there are still many shortcomings which need to be improved. And this thesis the author mainly focused on the research of the mobility state, and the handover process of the Heterogeneous network (HetNet). Firstly, the author made a deep research on the existing mobile location position technology, secondly the author did some research on of the mobility state of the network of LTE and LTE-A, and the method and process of the Mobility State Estimate. Thirdly, the author studied the concept and process of Device-to-Device (D2D).In this thesis, the author put emphasis on the handover between the cellular network and D2D, i.e., handover from the cellular network to the D2D and the handover from D2D to the cellular network.it is mainly about the improvement and the promotion of the process and theory, so that improve the performance of the network on the condition of the complex network structure. The main aim is to improve the performance of the network on the condition of the complex network structure by inproving the handover process.
