This standard specifies the inter-circuit domain interface (Iu) between the radio network subsystem (RNS) and the core network (CN) in the 2GHz WCDMA cellular mobile communication system that follows the 3GPP R99 recommendations and the 2GHz TD-SCDMA cellular mobile communication system that adopts the R99 core network. -CS interface), the inter-network subsystem (RNS) and core network (CN) packet domain interface (Iu-CS interface), and the radio network subsystem (RNS) and core (CN) broadcast inter-domain interface (Iu-CS interface) test methods. This standard is applicable to the network access test of the Iu interface part of the 2GHz WCDMA wireless network subsystem. It is also applicable to the test of the Iu interface of the TD-SCDMA/WCDMA single-vendor system. It can also be used for the compatibility test of the Iu interface.
