Technical Project Manager/SPOC, vGi – virtual Gi

Description:

The role was to be the SPOC (single point of contact) for one of three divisions.

The main purpose of the project was to extend the private address space for mobile data users. Due to the operator’s strategy of assigning private IP addresses to the users’ devices and the fact that the operator did not only have mobile data users, but was providing access via WLAN as well, the IP address space was getting close to its limits.
The resolution for this problem was seen in re-using the addresses (10.x.x.x) several times over by creating several virtual address spaces for internal-only re-use (e.g. 11.x.x.x, 12.x.x.x, 13.x.x.x).  

The project itself was run by the core network division, but other divisions – who were system owners of many systems along the traffic path – needed to be involved.

Responsibilities:

  • Ensure that all systems along the communication and signalling paths were capable of dealing with re-use of the IP addresses.
  • Coordinate the design, development (internal and external), test, and implementation activities and ensure that they took place according to requirements, timelines and budget as provided.
  • Coordinate issue resolution across all systems involved, including issues across systems from different vendors and systems owned by multiple divisions.

Duration:

  • 13 months

Network/Service Enhancement, Policy Implementation

Description:

The purpose of the project was to enable a new pricing concept that allowed to sell and enforce different maximum download speeds for different mobile subscriptions.

All systems along the call path had to be made compatible with this approach configuration changes had to be made and activated during low-traffic time windows.

This was a follow-up project to Project Manager/Coach AAA/PCRF (User Authentication and Policy Control) which built the technical capability to provide this functionality.

Responsibilities:

  • Identified the services that needed to be migrated
  • Prioritized the services for which the migration needed to be carried out based on technical and commercial criteria
  • Developed a migration concept and aligned it with all stakeholders from the various entities (incl. marketing/product management, design, testing, operations and service management)
  • Developed a migration plan that took in consideration the priority of the service as well as resource availability for implementation and live verification testing during as few nightshifts as possible at an acceptable risk level (incl. time for roll-backs in case of any major issues)
  • Carried out the migration for all services successfully with only one minor issue which did not require a roll-back and could be fixed during live operation the same day

Duration:

  • 9 months

Project Manager/Coach AAA/PCRF (User Authentication and Policy Control)

Description:

The main objectives of this project were focused on two areas:

  1. Upgrade of the AAA system to enhance capacity as well as to improve redundancy by changing the failover mechanism to a second, geographically separate site
  2. Implement a new PCF (Policy Control Function) in order to provide the product management teams with required functionality to limit throughput rates for various tariffs dynamically

Responsibilities:

  • Coached current project managers in order to improve their skillsets in a number of areas (e.g. risk, dependency and vendor management, communication across multiple project teams, testing and quality management approaches) 
  • Drove the approach to split the project in two pieces (AAA Upgrade and PCRF Implementation) in order to decrease complexity and reduce risk as well as to release pressure on the day-to-day operation
  • Updated plans and re-negotiate delivery schedules with the major stakeholders
  • Implemented contingency measures to ensure project progress 
  • Negotiated milestone dates and scope with dependent system delivery and product/service projects

Duration:

  • 10 months
