ETSI ETSI TS 124 525 V13.1.0 (2016-07)83GPP TS 24.525 version 13.1.0 Release 131 Scope The present document provides architecture and functional requirement

41、s for business trunking for the Next Generation Network (NGN). The present document also specifies the protocol requirements for the Next Generation Corporate Networks (NGCNs) to attach to the NGN (in particular the IM CN subsystem) and also any protocol requirements relation to application servers

42、provided in support of business trunking. Business trunking is a set of NGN capabilities that may be applied to communications between NGCNs using the NGN as a transit. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present
