In plain words

TS 33.224 specifies a generic push layer (GPL) using the GBA Push Function specified in TS 33.223. Its scope includes "a message format, cipher suites and processing model.", and assumes keys and other SA parameters are preinstalled in Push-NAF and UE as a NAF SA. The overview says it is reasonable to expect some Push-NAF-based services to benefit from sending multiple messages under one security association, using a per-device session concept.

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.
