In order to solve the problem that a variety of automated equipment to coordinate the operation of instability, monitoring is not timely, combined with “four lines a library” within the resources to design a system to coordinate the operation of the system. The system as the professional and technical supporting platform for intelligent operation and maintenance of “four lines a library”, will fully...
Based on the ideas of Priority-based polling transmission with high-efficiency, and self-adaptation to loading, this paper presents a new analysis model of MAC Scheme of wireless communication network, which has made possible the server capable of differentiating the stations of different priority levels under mixed services policy and which has improved the flexibility and adaptability of the system...
To solve the problem of user valuation in telecommunication networks, a networked approach has been proposed for discovering high-value users. A network is constructed from the phone call records data. Each node in the network presents a user, which attribute is communication costs, and each link stands for the call relationship, which attribute is the cumulative number of calls placed between the...
Orthogonal Frequency Division Multiplexing (OFDM) technology is applied into the 3GPP Long Term Evolution (LTE) systems. Based on the characteristics of frequency assignment and transmission scheme, the interference and compatibility related to co-existence of LTE is highlighted in this paper. The radio frequency (RF) system scenarios and the LTE-specific co-existence studies methodology are presented...
Both uplink and downlink capacity of cellular time duplex division-code division multiple access (TDD-CDMA) systems deploying multi-frequency are analyzed theoretically. The impact of multi-user detection, inter-frequency interference and different traffic types on multi-frequency TDD-CDMA system capacity are discussed. Simulation is done to evaluate the theoretical analysis and a good concordance...
