To build a trustworthy telecommunication network, it is believed that trust needs to be evaluated across end-devices, access networks, and core networks. As a result, many trust evaluation models have been proposed for telecommunication networks. However, these trust evaluation models are designed using different approaches, making it difficult for network operators to compare and analysis the performance of these trust evaluation models. To solve this issue, this recommendation provides a comprehensive set of metrics, recommended approaches and procedures for assessing trust evaluation models for telecommunication networks. This recommendation will serve as a guidance for network operators on comparing and selecting suitable trust evaluation models for their networks.
