Section 3: “Definitions and Acronyms” defines words and acronyms that are used in this Standard. Section 4: “Electronic Surveilla
42、nce Architecture” defines the WLAN-Interworking model, scenarios, and Electronic Surveillance architecture. Section 5: “Stage 1 Description: User Perspective” defines Electronic Surveillance from the law enforcement user point of view. Section 6: “Stage 2 Description: Network Perspective” defines El
43、ectronic Surveillance from the network point of view. Section 7: “Stage 3 Description: Implementation Perspective” provides the implementation perspective of Electronic Surveillance for cdma2000 WLAN-Interworking. Annex A (Informative): “Aspects of the e-interface” provides informative text on aspec
44、ts of the e-interface. Annex B (Informative): “Optional Messages” provides informative text on Stages 1-3 for optional Electronic Surveillance messages.
