Summary

► Migration phase and Detail Content:ü Phase I (2006) : 404K aged LE Migration to NGN (AXE & NEC aged LE , including 3 Tandem)ü Phase II (2007-2008) : 12 tandem, 65% loaded LE migration to NGNü Phase III (2009-2010) : remaining PSTN LE Migration to NGN

► SoftSwitch Deploymentü Phase I : 2 softswitch control areas (Islamabad and Lahore) are suggestedü Phase II : Suggest to deploy at least one pair of Softswitch in every telecom region (Based on 2008

NGN subscriber forecast)• Karachi need 3 pair of SoftSwitch and Lahore need 2 pair of SoftSwitch

ü Phase III : SoftSwitch in one telecom region should be separated based on NGN subs. For underpopulated area, suggest to deploy a pair of SoftSwitch to control several districts NGN subs.

► Exchange Migration Solutionü Tandem : replace with MGWü Local Exchange :

• Mainly, Migrate with MGW+MSAN• For LE whose capacity is less than 20K, migrate with MSAN

ü Remote Module : migrate with MSAN

All PSTN local network exchanges will migrate to NGN in the end of 2010

The ways Migrating Local Network To NGN

PTCL Local Network Deployment Suggestion

NGN Network Capacity and Bandwidth




Local Network Structure- No Tendam

Local switches directly connected each other, LE connection is very complex, and take too much transmission resourceLong distance traffic directly go to DTE, usually one MSU has 2 routes to DTE .this is most form of local networking

Local Network Structure- With Tandem

All Local switches are connected to two tandems (dual home) Long distance traffic go to DTE directly

Only 3 cities have tandems networking.

Rawalpindi & Islambad Local Network Status

Status Description:► There are total 9 LEs and 3 Tandems

► Mesh networking between LEs

► Mesh Networking between LE and Tandem

► All 12 exchanges have direct connection to DTE Rawalpindi

► Almost all exchanges except CITY-II, IBA I-10, IBA-2B, CANTT-II have direct connection to HCTERawalpindi

► IBA-2B have connection to NGN

► CANTT-III, IBA-1A have connection to WLL MSC

Analysis:

► Advantage : mesh networking between LE is ready for NGN evolvement

► Disadvantage: Too many connection make network structure complex

Ways to Optimize PSTN Local Network

LE complete replacement by NGN:

All PSTN subscriber replaced by NGN network.

Advantage: for aged device or Full loaded LE, it is a good choice, NGN network is low cost, fast networking, easy to develop NGN new services.

Shift LE Traffic to NGN( Stable migration solution):

In every district, all LE traffic shifts to TG( including intra-office traffic: call handling, charging and so on), TG acts as POI. In several future years LE will be migrated to NGN before their aging

Advantage: Fast and stable migrating PSTN to NGN, easy to develop NGN services for overall network, protect investment, centralizing charging and maintenance.

Usually there are 2 main ways For Local network migration to NGN

► In the future, when migrate LE, SoftSwitch can be used to control AG

► All traffic of LE can be shifted to TG controlled by SoftSwitch.

Advantage : Tandem In Megapolis Migrating to NGN

► Clear Network Structure : – Link between LE and DTE/HCTE can be removed because TG high

capacity performance► Less migrating risk:

– Compared number of LE, there are only 15 Tandem, less investment and risk to migrate to NGN

► Evolution to NGN smoothly :– When tandem NGN operation reach stable, SoftSwitch can used to

control AG migrating from PSTN LE. No need to adjust network structure again and no extra investment.

► Support NGN service deployment quickly– After tandem migrate to NGN, it is easy to deploy new NGN service




PSTN LE Migrating to NGN

► MGW setting: According to IP cloud and LE’s capacity, Following 2 migrating solution is recommended:– å : Softswitch + MSAN

– ç : Softswitch + MGW + MSAN

► For IP cloud covering area, Softswitch + MSAN mode is a good choice, otherwise, Softswitch + MGW + MSAN mode is proper to avoid no IP access problem.

► For PSTN LE whose capacity is less than 20K, Softswitch + MSAN solution is good, Otherwise recommend Softswitch + MGW + MSAN solution

Advantage : PSTN LE Migrating to NGN

► Flexibility : – Based on current IP bearer network availability, apply different PSTN LE

migrating solution► Less office:

– For PSTN LE whose capacity is less than 20K, use MSAN to replace and can reduce exchange office, reduce OPEX.

– Because MSAN can be maintained from remote► MGW can act as POI :

– For telecom district with few interconnecting requirement, MGW can act as POI

► Support Broadband access– MSAN can reconfigured to support narrowband and broadband access

simultaneously







Phase I : LE(NEC/AXE) Migration to NGN

Phase II : Tandem Migration to NGN

Full loaded LE Migration to NGN

Phase III: All LE PSTN/IN Migration to NGN





PSTN LE Planning Principle

General PSTN Local network migrating Priority:First, Tandem migrate to NGN

Second, LE migrate to NGN

PSTN LE Migration Benchmark:The aged switches should put into migration planning, and replaced year by year.

The switches which have function or performance problems should be replaced first.

The switches which MSU CP is loaded over 65% should be replaced soon. CP’s load over 65% means this area traffic is high

Advantage from PSTN LE MigrationHigh Service Capability : New service based on NGN technology can be deployed quickly

Cost Saving : Outdated exchange is heavy burden of operators in maintenance, while centralized O&M of U-SYS can reduce this cost greatly.

► PSTN exchange Migration in other places is the same with migrating solution in Lahore and Islamabad.

► At least one MGW in each regions of Islamabad area

►► PSTN exchange Migration in other places is the same with PSTN exchange Migration in other places is the same with migrating solution in Lahore and Islamabad. migrating solution in Lahore and Islamabad.

►► At least one MGW in each regions of Islamabad areaAt least one MGW in each regions of Islamabad area

SoftSwitch control Area Partition:► Area 1 (Islamabad) : CTR, FTR, MTR , GTR, NTR-I, NTR-II, RTR, ITR► Area 2 (Lahore) : LTR

SoftSwitch Deployment (Dual-homing):► Area 1 : one Softswitch in Islamabad, another in Multan► Area 2 : two Softswitch deploy in different office

Access device Deployment:► Tandem : migrate with MGW + MSAN► Large capacity(>20K) LE : migrate with MGW + MSAN► Small capacity(<20k) LE : migrate with MSAN

Transmission Resource:► IP transmission must be ready between MGW and SoftSwitch.► If IP ready, recommend to connect MSAN with IP link, reduce requirement for

MGW/E1► If IP not ready, connect MSAN with MGW via E1















Phase II: Full Loaded LE Migration

► In total 95 (not including 22 DTE) Siemens LEs, 42% exchanges load is over 60%.

► For full loaded PSTN LE, expansion is becoming more and more difficult because vendors are stopping PSTN exchange production.

In Phase II, Gradually migrate full loaded PSTN exchanges




Phase II: Softswitch Setting Suggestion

Local networking takes dual-homing solutioneach pair of softswitch planning 0.5M subscribersBased on forecasted subscriber scale, every Telecom Region at least having one pair of softswitch is reasonable.

Softswitch Setting Suggestion for PTCL

Softswitch Data Migration from Phase I

In phase I, there one pair of softswitch covers 8 TR(TelecomRegion). In phase II one pair of softswitch be proposed to set in every TR, so softswitch data of phase I should be migrated to softswitch of every TR.It is very easy for TG/MSAN to be reconfigured to registered in its own TR softswitch.
