In plain words

TR 21.905 defines QoS as Quality of Service. In TS 22.278, the requirement says "The Evolved Packet System shall have the ability to provide a quality of service equal to or better than the QoS requirements specified for GSM and UMTS.". TS 22.101 has a Quality of Service clause, and TS 24.008 uses an information element to specify QoS parameters for a PDP context.

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
