SCCP ANSI/ITU/TTC/CHINESE R13
ANSI 1996 / ITU 07/96 / ETSI 2001 / TTC 1997 /
CHINA 94, CAA 901 437
The Signaling Connection Control Part (SCCP) provides additional functions
to the Network Layer (NL) to cater for both connectionless as well as connection-oriented
network services to transfer circuit related and non-circuit related
signaling information between exchanges and specialized centers in telecommunication
networks (e.g. for management and maintenance purposes) via a
Signaling System No. 7 Network.
Standards
SCCP is developed according to the following
standards:
» ANSI rec. T.112 (1996), T1.116.2 (1996)
» China rec. P.R.C. 1994:10
» ETSI rec. ETSI 300 009-1 V1.4.3 (2001 - 02)
» ITU-T rec. Q.711 – Q.714 (07/96), Q752 (06/97)
» TTC rec. JT-Q.711, Q.712, Q.714 (04/97),
JT-Q.713 (04/2000)
Features
» Support for up to 253 users (SSN)
• Up to 1,048,576 simultaneous connections
per SCCP instance
» Multiple node support, up to 24 local nodes
» Multiple Country Network support, up to 24
separate signaling networks
» Support for Global Title type as 1, 2, 3 and 4 for
ITU-T and TTC, and 0001 and 0010 for ANSI
» Handling of protocol classes 0, 1, and 2
» Functions for segmenting/reassembling of long
messages
» Support for user data in the connect and disconnect
primitives
» Possibility to reconfigure SCCP during runtime
without loosing connections to applications or
running connections
» Possibility to add and change routing cases in
runtime
» Alarms generated by resource utilization thresholds
via management interface
» SLS load sharing controllable by SCCP user
» Broadcasting of SCCP management changes (to
other network nodes)
» Support for SSC messages and Importance
Parameter (ITU and TTC)
» Support for LUDT reception (ITU and TTC)
» Includes connection-oriented messages for TTC
(extension of standard)
» Signaling Relay Node functionality (SRP)
• Policy and accounting
• International SRP, relaying between different
signaling standards
» Handling of broadcasting of SCCP management
changes via management interface to support
geographical redundancy
» Load sharing between 16 possible routes
resulting from a GT translation
» Request of SCCP event statistics via management
interface for a specific SSN where applicable
Interface
The upper interface primitives establish communication
with the SCCP module. The thread-safe API
offers one function for each primitive for the upper
interface. The interface supports C/C++ or Java
code.
» N_CONNECT_req/resp/ind/conf
» N_DATA_req/ind
» N_DISC_req/ind
» N_NOTICE_ind
» N_STATE_ind
» N_UNITDATA_req/ind
Prerequisites
M3 (MTP-L3 & M3UA) , ITU 07/96,
ANSI 1996 & 2001, TTC 1992, China 1991,
ETSI 1997, IETF RFC 4666 (CAA 901 1817)
Software
» The thread-safe C/C++ API offers call-back functions
for supported SCCP primitives.
» The Java J2SE API provide a class library based
on an easy-to-use Event interface (subsclasses
of the java.util.EventObject class). It includes
classes for decoding & encoding of SCCP primitives.
