Signalling Link
Two Signalling nodes represented by their point
codes can be connected using Signalling Link.
In European Standard links between nodes are full-
duplex 64kbps within an E1 facility.
Signalling Link can be TDM or IP based.

Signalling Link Set
In SS7 one or more signaling links can be
connected to the same two endpoints that
together form a signaling link set
Signaling links are added to link sets to
increase the signaling capacity of the link set.

Signalling Route Set
Signalling Route - Chain of signalling link sets and signalling transfer points which can be used as a path by the signalling point when routing a message towards a specific signalling point
Signalling Route Set - Combination of all permitted signalling routes that may be used to pass signalling messages from a signalling point to a specific destination
Each Signalling Route Set are associated with a Signalling Route Set Parameter set that defines its own signalling function.
In general, the predefined parameters are the most suitable ones to be used.

GT Analysis
GT Analysis - Analysis in which the numbering plan, nature of address, and translation type determine an analysis tree from which the analysis result is derived, based on the digit sequence included in the address or translation type
GT Translation - Analysis of the global title in order to find out the signalling connection control part (SCCP) routing address

SCCP
The SCCP layer can use a Signalling Point Code
(SPC) as the destination SCCP address even when
the functional application and the MAP layer uses a
GT
That there must be a route set on the MTP level to
all Signalling Points (SP) known by the SCCP.
Applications that use SCCP services are defined as
subsystems which are identified by a Subsystem
Number (SSN).
SCCP
The subsystems can be SCCP management
(SCMG), MSC MAP, VLR MAP, HLR MAP,
INAP, OMAP, and possibly some network-
specific subsystems, like Base Station
System Application Part (BSSAP).

Trunk Group (CGR)
Circuits - Transmission channels permitting
bidirectional transmission of signals between
two points, to support a single
communication.
Circuit Group - Group of circuits that have the
same purpose and are traffic-engineered as a
unit.
Trunk Group (CGR)
External circuit groups are created to connect
circuits between two exchanges.
These circuits are used for carrying speech
or data between these network elements.
The circuit group identifies the direction and
register signalling.

Tree Analysis
Digit analysis - It is the Analysis done in CM for Identifying dialed digits and routing it to respective Destinations.
Analysis tree - A chain of records in an analysis file, used for analysing different types of digits.
1. Circuit group (TOCs and PBX calls)
2. General Parameter file PRFILE (in MOCs)
3. End-of-Selection analysis (forwarding and roaming calls)
4. MSISDN digit analysis (some roaming calls)

SIGTRAN
Configuration of SIGTRAN consists of an
SCTP part and an M3UA part.
SIGTRAN
(SCTP)
SCTP is a reliable transport protocol
operating on top of a potentially unreliable
connectionless packet service such as IP.
It offers acknowledged error-free non-
duplicated transfer of messages

The M3UA in SIGTRAN (SS7 MTP3-User
Adaptation Layer) provides the applications
with the same services as the MTP3
It routes the MTP layer 3 messages from the
applications to the correct SCTP
associations.
The M3UA Signalling channel acts as a link
to the logical SCTP association set which
leads to the next network element

H.248
H.248 or MEGACO is the interface between
MSS and MGW to control user - plane
resources.
This interface is implemented by establishing
control connection between signalling unit
(CCSU / SIGU) in MSS to signalling unit
(ISU) in MGW.
In MSS, this is implemented by creating
MGW and in MGW it is implemented by
creating virtual MGW.
User plane resources for MSC server can be
created only after H.248 interface is created
between MSS and virtual MGW.
H.248
To configure H.248 control interface for MSC Server
1. Add new MGW - Select the signalling unit at MSS side, which communicates with the MGW.
2. Configure MGW
a. Add MGW to MSS's MGW database.
b. Select the signalling unit in MSS side, which communicates with
the MGW.
c. Configure H.248 –specific data.
d. Configure E.164 address of the MGW.
e. Configure each virtual MGW 's domain name and IP address.
f. Configure peer MSS's IP addresses and domain names of each
virtual MGW.
3. Register MGW
a. Check that registration is enabled from the MGW at MSS side.
b. Activate registration process in the MGW.

Digit Analysis - Preanalysis
Preanalysis –
To examine the numbers being dialled in order to establish the type of call being made.
To identify a service, service group or emergency call.
To send dialled digits modification instructions on how to remove or add dialled digits.
Digit Analysis - Preanalysis
To analyse the nature of the dialled digits and change it to the “characteristics of number”.
Identify local calls (add local area code).
Recognise a certain dialling pattern (prefix) from the MS in order to proceed routing based on calling line identity (CLI).
Recognise prefixes for CLI presentation (whether the CLI is presented to Subscriber B or not)

Routing attribute analysis –
Tree to be used for different calls depending
on the attributes associated with them.
Intermediate announcement to calling (or
redirecting) subscriber with a Chargeable /
free announcement indication.
Routing Attribute Sub-Analysis & Final
Result
Routing attribute analyses are made before the CM
digit analysis at points where the called or redirected
number is brought to the digit analysis
They are not made for roaming or handover
numbers and after number modification has been
done.
The default result is that the analysis does not
change the digit analysis tree and There is no
announcement for the subscriber

SPRs
SPR - SPR instructs the exchange to retain
the call in the MSC because some other
actions need to be done to the call before it
can be routed out
SPRs
The SPRs used are:
· HLRENQ SPR
· GSMEND SPR
· SPR with inter-MSC handover
· Number modification SPR
· Announcement SPR
· SPR with data call; the call must pass through the modem pool before being routed out of the exchange
· SPR with an IN call
SPR - HLRENQ
During every MTC, an HLRENQ must be
performed to find out the MSC where the
subscriber is located at the moment.
SPR - HLRENQ
Signalling messages from the MSC to the
HLR can be routed using the two main
principles:
· routing on label
· routing on Global Title (SCCP routing).
SPR - HLRENQ
HLRENQ routed on label
The definition for the SPR HLRENQ must
contain the signalling point code from the
HLR
HLRENQ routed on Global Title
It is the most flexible and elegant way of
routing HLRENQs to the HLRs. Only one
SPR for HLRENQ,

SPR - GSMEND
GSMEND SPR – Mobile Terminating Call
For a mobile-terminated call, the MSC
receives its own MSRN back from the Trunk /
HLR after HLRENQ which is then further
analyzed in respective tree and the call is
routed and terminated using GSMEND.

IMSI Analysis
IMSI Analysis –
It is defined in all VMSCs in the visited PLMN
