ThiS TS covers the security mechanisms and procedures necessary to protect all TCAP user
messages which are sent between different security domains. The complete set of enhancements and extensions to
facilitate security protection for the TCAP protocol is termed TCAPsec and it covers transport security in the TCAP
protocol itself and the security management procedures.
ThiS TS contains the stage 2 specification for security protection of the TCAP protocol. The actual
implementation (stage 3) specification can be found in TS 29.204
