In the next 10 years, the telecommunications sector will be dominated by the deployment of pervasive networking available in a wide range of heterogeneous scenarios applying 5G (and beyond) technologies. SDN, NFV as well as Network Sliding Technologies used by 5G will provide a ''softwarization'' of the network functional elements, opening the ecosystem of network providers to a vast number of suppliers from traditional manufacturers to start-ups focusing on specialized functions. Due to the need to assert the expected interoperability of the introduction and evolution of this set of Network Functions, a set of validation tools is needed to explore traffic patterns according to different scenarios and thus allow the performance of the software modules to be evaluated. This research work presents the design of software tools that aim to provide a way for generating signaling and user traffic in 5G networks, enabling the definition of novel pure-software testing environments for 5G that includes real signaling and user traffic. The tools have been designed to support a set of testing signaling procedures that cover the basic main functioning of 5G networks and that allow for the transmission of user traffic over the network. The tools have been implemented and licensed as Open Source and have been validated through their deployment in a virtualized 5G environment that includes a 5G core network.

“…For the sake of improving capacity and spectrum utilization, 5G systems further develop MIMO techniques by manufacturing antennas into miniaturized integrated devices with massive units. If traditional testing methods are still adopted to 5G systems, a great number of cables are demanded which greatly increases the error rate, complexity, and cost of test equipment [2]. On the contrary, OTA testing possesses superiorities of repeatability, reliability, and high measurement efficiency [3] making it leading method of 5G and emerging systems.…”

With the fast development of communication techniques, over-the-air testing has developed into the main testing method for current communication systems due to its advantages including no cable connection, high measurement efficiency, and independence from environment. OTA testing has become almost the only solution for 5G system testing especially after the popularity of 5G massive multiple-input-multiple-output. In this paper, we summarize the three main methods of OTA testing including the reverberation chamber-based method, the radiation two-step method, and the multiprobe anechoic chamber- (MPAC-) based method, among which we focus on the MPAC method systematically. In the MPAC method, there are two main channel synthesis techniques that have been heavily studied, namely, prefaded signal synthesis and plane wave synthesis. We summarize the current main research based on these two techniques including probe configurations, probe selection algorithms, and probe design based on the PFS technique and the design of plane wave generators based on PWS technique. The main comparisons are made for the performance of different probe selection algorithms and the performance of different plane wave generators as well as the latest advances.

“…They are exemplary only and the intention is to give an idea about the beam selection and the use of the metrics to highlight the beam selection procedure. Figure 3 and onwards present drops of the GSCM UMi channel model onto the sector (see [1] for the sector presentation). The sector size in these examples is 120° in azimuth and 60° in elevation.…”

“…The same is valid even for the test system development where the complexity and the cost are very essential factors in searching for the industry acceptance. The paper [1] presents some comparison between 4G UE and 5G BS testing aspects. More confined presentation on the 5G BS testing and on the metrics are in [2], [3].…”

“…Regarding the LTE MPAC systems wellknown and established test system validation metrics exist. The proposed setup in [1], [2], [4] is an extension of the LTE MPAC but because of different test system requirements the metrics for the proposed test system aim to different parameters. This paper neither studies the existing LTE MPAC metrics nor analyses the requirements for 5G test systems for UE or BS.…”
