name: QoE
full_form: Quality of Experience
context: The following requirements apply for supporting enhancement of service function chaining for 5G networks: - The network operator shall be able to define and modify service function chaining policies for steering traffic on per application per UE basis through required service function chaining with ordered service functions to improve the userâs QoE. - Service functions chaining policies shall be able to distinguish between upstream and downstream traffic. - The coexistence of traffic with and without service function chaining shall be supported. - Service function chaining shall provide suitable means for authorized third parties to request a chain of service functions provided by the network operator based on operatorâs service function chaining policies. - In case of roaming, the HPLMN shall be able to apply traffic steering policies and service function chaining polices for home routed traffic. - In case of roaming with local breakout, the HPLMN shall be able to provide the traffic steering policies and service function chaining policies to the VPLMN providing local breakout with support of service function chaining. - Service function chaining shall support deployments where the Hosted Services are provided by the operator and deployments where the Hosted Services are provided by a third party.
description: Quality of Experience (QoE) refers to the overall performance and satisfaction level of a user's experience with a service or application, taking into account various factors such as latency, throughput, packet loss, and jitter. In the context of 3GPP TS 22.261, QoE is an essential metric for evaluating the effectiveness of service function chaining in improving the user's experience.
explanation: QoE is classified as a Measurement because it quantitatively assesses the user's satisfaction with a service or application, which is a critical aspect of service function chaining. The paragraph highlights the importance of QoE in evaluating the performance of service function chaining policies and their impact on the user's experience.
