TUP
MTP user parts ISUP (ISDN User Part) • It provides control-functions and signaling, needed in an ISDN, to deal with ISDN subscriber calls and related functions. TUP (Telephony User Part) • It provides all necessary functions and signaling for dealing with a telephony user. • TUP is being replaced by ISUP in telecommunication networks. DUP (Digital User Part) • This UP is used for purposes such as file transfer and related signaling.
SCCP • The MTP was designed for the real-time applications of telephony. • The connectionless nature of the MTP provides a low-overhead facility suiting the requirements of telephony. • Regarding GSM, other applications such as network management need services such as expanded addressing capability and reliable message transfer. • The SCCP was developed to meet these requirements. • The SCCP also sends its messages through the MTP. • The SCCP provides functions for completely new services, for example, non-circuit-related signaling. • Some functions, not directly related to users, but necessary for network control, are used. • The main reason is that they are necessary for serving applications in higher layers and for maintenance purposes.
SCCP • These functions use SCCP services: Transaction Capabilities (TC) – First introduced in 1984, TC provides the mechanisms for transaction-oriented applications and functions. Operation and Maintenance Application Part (OMAP) – Specifies network management functions and messages related to operation and maintenance.
