LTE Network OperationsOSS Tools Landscape / General

Regardless of managed network technology (2G, 2,5G, 3G, 4G / LTE, IP),the OSS architecture i.e. the NOC landscape stays unchanged

and is capable in the given setup to manage also the LTE operations.

The TMF/eTOM based OpsMod @ NwOps applies for LTE operations.

In case of a proprietary Element Management System (EMS) northbound IF (NBI), a specialarrangement w/ Customer Service Provider (CSP) and OEM supplier are required to open the

protocol for 3rd party so to enable NSN and/or NSN-partner to access nw element data.

• The CSP ―A‖ was established in 1988 and become known as ―Mobile Satellite Corporation‖ to be renamed after merger

between ―Alfa Corporation‖ and ―ABC Communications‖. The recent rebranding made this venture known to broader publicity under the name of ―SkySierra‖, a company that provided comprehensive set of mobile satellite communications

services.

• In CY2011, the CSP ―A‖ signed a 15-year services delivery agreement with ―MoveOn‖ for LTE/4G technology.

• The CSP ―A‖ planed to provide network capacity on a wholesale basis to wireline and wireless communication service

providers nationwide, as well as to various cable operators, web players, and content providers.

• NSN was short listed, and eventually got contracted on Build-Operate-Manage (BOM) basis, comprising following services

scope: nw planning (NPO), nw implementation (NI, 40.000 eNodeB sites), and nw operations (NwOps).

• The business objective was to access 92% of the population in the geography by CY2015.

• The Total Contract Value over 8 years is app. 7 BN EUR.

• E// submitted a hostile bit w/ equivalent scope of services, and the CSP ―A‖ has executed the contract exit option, following

stepped out of this long term contract with NSN.

Q&A 47

Backup 48





Q1: Will the presented slide deck be distributed / made available for broader community?

A1: Yes, the slide deck is available in intranet as of now, and will be distributed after delivery of the

2nd enabling session.

Q2: With regards to the HC benchmark value for “routers/IP/switches” (page 18, FM section),

the FM benchmark value of 750 nodes per NOC/GNOC person seems to be much too high.

A2: Proportionally the total qty was low, thus the importance was not that high weighted. So far there

is not much practical experience available in this regards at NwOps. Following, an iterative verification was

made with other SBU, and the value was corrected down to 200 (as delivered during 2nd enabling session).

LTE Network OperationsQ&As 1 / 4





Q3: One question regarding HC dimension. For example, FM 1 person, this slide said that LTE

FM, If there are 2G/3G and LTE in the customer network condition, is it possible to consolidate the FM

person?

A3: Regarding the HC for FM for different technologies---if both 2G/3G and LTE are there-----then

surely we need to consolidate the persons, depending on case to case. Its not like, we will keep different

persons for 2G3G and LTE. And we will consolidate the persons for mixed technologies, but the level of

consolidation will depend on case to case. In particular you would be analyzing the workload of the respective

HC for FM 2G. Than you would be willing to x-check if the Fault Management OSS tool environment (whatever it is for 2G and will be for 3G) will be unified system - one OSS tool/monitor for 2G and for 3G, so the FM

HC would be viewing one monitor (at best) and would be serving one system terminal (at best). One person

can view two terminals, and serve two systems, but …it is not the best option for the efficiency reasons.

In addition, you would be looking for engineer who will be capable of accepting additional training to become

multi technology capable. And finally, you would be looking for someone who is good and experienced and

performing well w/i existing organization to develop her/him for the new technology.






Q4: One question with regards to the AM - Alarm Monitoring for Radio (eNodeBs) (page #18).

Provided benchmark value – “No of Nodes – 1000 / Assumption 600 alarms/nodes/month” implies thatthere will be approximately 20 alarms per day created by one eNodeB. This is quite high no of alarms

for a single LTE network element in Radio domain.

A4: The anticipation is made in this way due to expectation that the completely new technology will at

least during initial period have increased total qty of alarms, and some of these alarms will be more time

consuming to be clarified. The statement is based on NSN experience from previous technological changes

such as 2G/3G.






Q5: Contrary to the present 2G/3G MS Ops Model, the RAN SLM tasks and responsibilities will

converge with CM role. Please, confirm. The reason for asking is because there seems not to be any

resource mapping for above job function in Level-5 of the MS Ops Model. The SLM means in this

context Second Level Maintenance i.e. Tier2 or Back Office support for Fault Management and

Configuration Management.

SLM support function falls under the same umbrella of NOC (Network Operations Center). Ie NOC –

Fault Management consists of FLM (ie First Level Maintenance which is primarily outsourced to

subcons) and SLM.

A5: The question + clarification above indicates the phased out NwOps approach that is not aligned

with the given MS OpsMod. The official MS OpsMod terminology is not using front/back office, 1st level / 2nd

level maint, etc.

It would be advisable to trigger MS OpsMod enabling for the members of the local team including technical

management level and sales, by participating in the OpsMod training sessions (see link below, free of chargeinteractive on-line solution), and on top to trigger the "MS OpsMod Assessment" exercise and based on

findings to define action items for alignment on given MS OpsMod landscape.

LTE Network OperationsLTE SAE (3GPP) / NE Basic FunctionalityThe LTE network elements are as follows:

• The Mobility Management Entity (MME) is the control plane (C-plane) functional element in

EPC. The MME manages and stores the UE context, generates temporary identities and

allocates them to UEs, authenticates the user, manages mobility and bearers, and is the

termination point for Non-Access Stratum (NAS) signaling.

• The Serving Gateway (S-GW) is the user plane (U-plane) gateway to the E-UTRAN. The S-GW serves as an anchor point bothfor inter eNodeB handover and for intra 3GPP mobility, i.e.

handover to and from 2G or 3G.

• The Packet Data Network Gateway (P-GW) is the U-plane gateway to the PDN, e.g. the

Internet or the operator’s IP Multimedia Subsystem (IMS). The P-GW is responsible for policy

enforcement, charging support, and user’s IP address allocation. It also serves as a mobility

anchor point for non-3GPP access.

• Most often, the S-GW and P-GW functions are combined in one network element, System Architecture Evolution Gateway oftencalled SAE Gateway (SAE-GW).

• The E-UTRAN contains only the base station, eNodeB, which provides the air interface to the UE.
