![]() Provided modern probing solutions and investigated all the complaints of The Anritsu solution relating to signalling issues. Managed change requests and incident/event tickets in the BMC remedy system from different departments. ![]() Worked in the transport and IP support department served as an implementer and operation engineer of the MME, S-PGW, SGSN(USN), GGSN(UGW), DNS, CG and all nodes in the chain in a group of three engineers. ![]() During this project, also to deeply discuss the designs to improve the sub-optimal solutions and successfully achieve agreements on the final solution which is much more efficient, reliable and realistic. Introducing the Alternative Roaming Partner (ARP) service while adding the Gx interface to all the MVNO and private APNs, thus offering the option to choose the ARP provider when roaming in Europe. Upgrading software, installing new patches and rebuilding the core nodes to be VOLTE enabled (MME, P-GW and S-GW) also adding related interfaces like Rx to offer the VOLTE services on top of the current LTE network. Provide the risk assessment advices to the project managers and suggest test cases to the test manager as well as new solutions for the scenarios which fail or may introduce high risks. Ěcting as an active member of the FOM (Future of Mobile) project. Introducing LTE service for prepaid subscribers including the evaluation of the current capacity of the S/PGW and implement new APNs in three different nodes with proper redundancy, as well, risk assessment of the migration to the new online charging platform. Providing the internal decision tree in the PGW to be used in the rainy day cases when the Gx is down. Introducing the Sy interface over diameter and connecting it to two separated online charging systems, state-full mechanism (to let redundant PCRF have the session information and continue serving established sessions uninterrupted. Integrating the PCRFs in the new environment, also expanding the back ends to support internal SPR to be provisioned directly and phasing out external SPR. ĝeveloping and implementing an appropriate decision tree in the current working logic tree without interfering with other services and mostly optimised in order to avoid extra CPU cycles. The proprietary algorithms enable self-configuration of newly deployed sites or technological features to minimize human intervention and reduce operational costs. Working within the E2E Data department accountable for developing and maintaining the PCRF and PCEF logic tree. This future-proof optimization solution enables a 60%* OPEX reduction through the automation of frequent and time-consuming tasks such as detecting overshooting cells, PSC/PCI clashes and incorrect settings of neighbour lists. The solution proposes LTE IMSI Enrichment and individual IMSI geolocation for advanced troubleshooting. ![]() This information can be used to improve network planning by recommending additional small cells, proposing mobility scenarios monitoring, etc.Īstellia’s Nova solution analyzes 100% of real subscriber traffic and offers native end-to-end troubleshooting from radio to core network by exploiting RRC call traces and probe data. Its Advanced Predictive Algorithms distinguish indoor/outdoor, static/mobility calls (high speed train, motorways) and coverage & traffic hotspots. This geolocated information can be injected in operators’ big data lake to enrich customer experience analysis and can be leveraged by marketing for geo-fencing, geo-marketing etc. Radio engineers can obtain multi-point geolocated positioning every second for every subscriber and better understand issues they experienced. The customer-centric solution embeds best-in-class massive geolocation, reducing the need for drive tests by 90%*. RENNES, France - Astellia, leading provider of network and subscriber intelligence for mobile operators, announced today that its award-winning Nova RAN is now available as a fully virtualized RAN optimization solution, supporting multi-technology and multi-vendor networks.
