This Standard was deve
41、loped by ANSI-Accredited Telecommunications Industry Association, Engineering Committee TR-45. This Standard defines the interfaces between a service provider (SP) and a Law Enforcement Agency (LEA) to assist the LEA in conducting lawfully authorized electronic surveillance (LAES) for Push-to-Talk o
42、ver Cellular (PoC) services in a cdma20001network. There are four annexes in this Standard. Annex A and Annex B are both informative and are not considered part of this Standard. Annex C and Annex D are both normative and are considered part of this Standard. Requirements Language The following lang
43、uage is used to signify the requirements in this Standard: “Shall” and “shall not” identify requirements to be followed strictly to conform to this Standard and from which no deviation is permitted. “Should” and “should not” indicate that one of several possibilities is recommended as particularly s
44、uitable, without mentioning or excluding others, that a certain course of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course of action is discouraged but not prohibited. “May” and “need not” indicate a course of action permissible within
45、the limits of the document. “Can” and “cannot” are used for statements of possibility and capability, whether material, physical or causal. 1cdma2000 is a registered trademark of the Telecommunications Industry Association (TIA-USA).

47、etwork. LAES capabilities enable a PoC Service Provider (SP) to deliver the intercepted communication content (e.g., voice) and communication-identifying information to an authorized Law Enforcement Agency (LEA). In this Standard, “intercept subject”, “surveillance subject” or “subject” is a subscri
48、ber to a PoC service whose communications have been lawfully authorized to be intercepted and delivered to an LEA. For the purposes of this Standard, “communications” is communication-identifying information (CII) or communication content (CC), or both CII and CC. 1.1 Purpose The purpose of this Sta
49、ndard is to facilitate the SPs assistance to law enforcement. This Standard defines a method to support LAES in a cdma2000 network providing a PoC service. 1.2 Scope The scope of this document is to define electronic surveillance capabilities required to support LAES and the interfaces between the SP and an LEA to assist the LEA in conducting LAES in a cdma2000 network providing a PoC service. The PoC service supported in this specification is based on non-IMS PoC. In this document, the PoC Service Provider and the cdma2000 Network Provider are the same. Separation of the PoC Servi
