Abstract: The end-to-end experience of a wireless customer depends on at least data throughput, data loss, and latency, as well as other characteristics. The user’s quality of experience (QoE) can be determined based on applications and measurements taken at the application layer of the user’s user equipment (UE) and information at the session level at the UE initiated and configured by an operator at the start of the session. The QoE is an application layer measurement configured by the operator and reported inside the application layer. When a UE is performing an inter-system handover, the QoE measurement configuration of the current session cannot be transferred from the source network to the target network.

Abstract: This disclosure describes methods and systems for configuring, performing, reporting, and analyzing user quality of experience measurements of virtual network slices in a wireless communication network platform. The measurements are performed by the user devices and thus more accurately reflect a true user experience with respect to network latency, throughput, and/or data loss. The measurements are triggered via a messaging procedure involving the core network and the access network of the wireless communication network platform. The measurement results are reported by the user device to the network side for optimizing network resource allocation and configuration of the virtual network slices to improve user experience.

Abstract: Methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to related to reselecting a network in a network sharing split architecture. In one exemplary aspect, a method for wireless communication includes a central node associated with a previous network receiving a rerouting message from a distributed node indicating that a network for the terminal is reselected from the previous network to a new network. The method also includes the central node associated with a previous network transmitting an allocation message to a central node associated with the new network.
