The Service trigger algorithm is the core of the entire IMS system platform, which can affect the work efficiency and service quality of the entire system. In the early days, the service trigger algorithm officially defined by 3GPP can no longer meet the overall requirements of current big data and big user information services. In order to meet the Service needs of the multimedia network platform and the huge user group in the future, this paper conducts an in-depth study on the official Service trigger algorithm, and proposes an IMS packet Service trigger algorithm based on the double filter criteria. This algorithm achieves the goal of quickly processing multiple services by combining the packet Service trigger mechanism with the iFC+sFC dual service filter criteria. The simulation results show that the new service triggering algorithm can effectively reduce the overall session setup delay, improve the system throughput, and greatly improve the IMS system service triggering efficiency.

Reconfigurable Intelligent Surface (RIS) stands out for its unique low-cost and low-energy characteristics, which is expected to break through the uncontrollability of wireless channels and build an intelligent programmable wireless environment. In this paper, we consider a RIS-aided downlink communication system including one access point serving a user terminal and derive closed-form expressions of ergodic achievable rate and outage probability. Then, we analyze the ergodic achievable rate in terms of high signal-to-noise ratio slope and power offset. A phase shift optimization scheme is also proposed to improve the ergodic achievable rate. Finally, simulation results are conducted to validate the accuracy of the analytical results. According to the simulation results, the proposed phase shift optimization scheme can improve the system performance, compared to the random phase shift scheme.

As a fundamental countermeasure for network management and security, traffic classification has attracted public attention for a long time. All the time, the presence of zero-day traffic, network traffic of unknown applications in a classification system, leads to a significant reduction in the practicability and effectiveness of conventional traffic classification methods. This paper innovatively proposes a traffic classification scheme named DACS, which achieves accurate zero-day traffic detection, application traffic classification and high-performance incremental model updating, fitting for open-world and online traffic classification with plenty of zero-day traffic. DACS uses training samples to cross-simulate zero-day flows and combines the idea of distributed training. With a two-layer structure and a special voting mechanism, DACS is able to perform comprehensive traffic classification tasks in hybrid unknown traffic. In addition, DACS provides great convenience for updating the system knowledge and supports efficient incremental updates. The evaluations with real-world traffic verify the core advantages of the proposed scheme. DACS maintains over 95% classification accuracy on a public dataset (NUDT_MobileTraffic), which is better than the compared methods, and it only needs 1/K retraining computational cost to achieve model updates for new applications, where K is the number of sub-classifiers.

In this paper, results for non-stationary channel statistics based on the wideband high-speed train (HST) channel measurement in the rich-scattering viaduct scenario are presented. Due to the fast movement of the train, both the fading characteristics and the Doppler-delay statistics change rapidly with time. The measurement campaign is implemented on the Guangzhou-Shenzhen passenger-dedicated railway at a central frequency of 2.4 GHz. The parameters of multi-path components (MPCs) are estimated by the Subspace-Alternating Generalized Expectation-maximization (SAGE) algorithm. The large-scale fading properties and the small-scale Doppler-delay statistics, including path loss, shadow fading, Rician K factor, number of MPCs, root-mean-square (RMS) delay spread, RMS angular spread, power-delay profile (PDP), and Doppler-power spectrum are analyzed. The non-stationary statistical models of the above parameters are given based on the measured results. The correlation property is characterized by the correlation matrix distance (CMD). It is shown that the HST channel in the rich-scattering viaduct scenario has strong non-stationarity characteristics. This work provides references for the design of HST communication systems and promotes technical developments.

High-speed train (HST) communications are challenging due to fast time-varying channels and Doppler effects. Recently, reconfigurable intelligent surface (RIS) has been envisioned to be one of the most promising technologies for tackling the difficult problems of HST communications. In this paper, we first propose a transmission model of the HST communication system using RIS on the train side. Then, different strategies for mitigating delay spread (DS) are compared from the perspectives of the phase shift set design and deployment of the RIS. In addition, we derive the spectral efficiency (SE) expression of the proposed system. Numerical evaluations validate the analytical results and reveal that the RIS on the train side not only increases SE but also reduces DS.

This paper investigates integrated sensing and communication for an ambient backscatter communication (AmBC) system. The backscatter devices (BDs) modulate information over ambient orthogonal frequency division multiplexing (OFDM) signals, and the receiver (RX) realizes joint localization and information detection of the BDs. The system model is first established and the link-layer protocol is designed. Then the discrete Fourier transform (DFT) based and compressed sensing (CS) based methods are proposed to estimate the locations of BDs. The attenuation coefficients of the paths backscattered by BDs are estimated through least square (LS) method, and finally the information transmitted by the BDs is decoded. Simulation results have verified the performance of the algorithms, and it is shown that the larger bandwidth and antenna aperture are beneficial to improving the localization accuracy.

Directed Graybox Fuzzing is an enhanced fuzzing technique that is widely used in security testing of network communication protocols, desktop software, file systems, etc. It guides the execution flow of the program to the code area of the target site by constructing specific input data, and realizes the test of the specific code area. It is usually used in scenarios such as patch testing, crash reproduction, and static analysis report verification. However, we found that coverage-guided tracing used by the existing Directed Graybox Fuzzing not only has high performance overhead but also has little value, because most test cases cannot discover new execution paths, and are even less likely to reach the target area. It doesn't make much sense to trace the coverage of these test cases. To address this challenge, we propose a new coverage-guided tracing mechanism and implement it prototype, WindArms. It will only trace the coverage of those which can discover new execution paths or reach the target area to reduce the performance overhead of those meaningless coverage-guided tracing. Our evaluation show WindArms not only significantly improves the performance of Directed Graybox Fuzzing, but also can discover security vulnerabilities in real-world software.

In this paper, we propose the Smart Software-Defined Wide Area Network (SD-WAN) Architecture, which combined the traditional SD-WAN and Segment Routing over IPv6 (SRv6) to realize an end-to-end SRv6 tunnel connection. Compared to traditional SD-WAN, the Smart SD-WAN can integrate with the underlay network to realize the collaboration of underlay and overlay. In this way, many services such as the ability of underlay network slicing when subscribers have bought the underlay network slicing service can be used. Furthermore, the Smart SD-WAN can provide differentiated, guaranteed Service Level Agreement (SLA) service and integrate virtual network elements in the cloud to provide service function chain (SFC).

With the development of unmanned aerial vehicle (UAV), the air-ground collaborative communication network which composed of UAV and ground base stations has also been developed and innovated. It can improve the performance of a delay tolerant network (DTN) consisted by a single network node. In this paper, we conduct a comprehensive evaluation and analysis of the performance of DTN air-ground cooperative networking through various features, such as UAV's the movement mode, movement speed, node cache, message survival time, network node density, routing protocol and others. The results show that the addition of UAV relay nodes can effectively improve the information transmission efficiency of DTN. In the scenario of large-scale node air-ground cooperative networking, air-ground cooperative networking is suitable for time-sensitive services and can improve the message delivery rate by 75% in a low message survival time.
