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. ZNCC

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.

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).
![Page 15: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/15.jpg)
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.

SIGTRAN(M3UA) 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.
![Page 44: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/44.jpg)
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
![Page 45: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/45.jpg)
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 MGWa. 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 Sub-Analysis & Final Result
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
![Page 186: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/186.jpg)
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
![Page 187: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/187.jpg)
SPR - HLRENQ
During every MTC, an HLRENQ must be performed to find out the MSC where the subscriber is located at the moment.
![Page 188: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/188.jpg)
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).
![Page 189: NSN Core Complete Integration](https://reader035.vdocuments.us/reader035/viewer/2022081420/55cf985c550346d0339735c0/html5/thumbnails/189.jpg)
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 area.
The MCC and MNC parts of IMSI are used to derive the correct PLMN.
Usually the first two digits of the Mobile Subscriber Identification Number (MSIN) are used to indicate the HLR within the subscriber's PLMN.
