4.1 Concepts

A network request session is a session in the mobile network when the network checks for UEs that have the capability to provide requested information.

An UE request session is a session in the network when the network has found an UE that has the capability to provide the requested information and the request is forwarded to the UE.

A recording session is a session in the UE when it initiates recording of the requested end user service/end user service type and record the requested information.

4.2 Background

The collection of QoE information for a specified end user service/end user service type either from UEs in a specified area or specific UE. The collected information is transported to a collection centre, where it can be analysed and/or KPIs can be calculated.

A collection can be requested by an operator technician via the management system to the traffic network. As the network do not have any knowledge which UEs have the capability to record the requested data, therefore the UEs will report whether they have this capability or not when a session set up. UEs that has this capability that match the request from the management system will be requested to start recording the requested information when the request constraints are met. The UE will make the recorded data available for management system.
