Despite this growth, Telenor Pakistan network congestion issues are known to Telenor customers. They include different issues like, voice distortion, anonymous voices with connected call etc.
These issues were because of :
Introducing the USC
To enhance network competitiveness, Telenor Pakistan decided to introduce a new type of HLR to upgrade its existing HLR network. To this end, Telenor Pakistan selected Huawei’ s unified subscriber center (USC), which is a new-generation HLR developed by Huawei. With the following technological advantages, the USC can fully solve the problems that Telenor Pakistan’ s existing HLR network has encountered:
Capacity for tens of millions of subscribers: The USC enables the centralized storage of subscriber data across the entire network; simplifies the existing HLR network; and enables unified management of subscriber numbers, without the need for number segments. Existing network capacity and subscriber growth forecasts indicate that the introduced HLR needs a minimum 40 million-subscriber capacity. The Huawei USC possesses this capacity.
Distributed deployment: The logically unified HLRs support geographically distributed deployment. After subscriber data is centrally stored, HLR network reliability becomes a critical element that the traditional disaster recovery mode cannot satisfy. The USC, however, allows the HLRs to be distributed in different geographical regions; these share traffic loads and ensure HRL network reliability.
Lower signaling load: The USC supports access for long-haul roaming subscribers. Subscriber data can be internally queried in the home through the IP network, thus using far less signaling resources.
Smooth network evolution: To meet network evolution needs, the USC is built on a converged architecture. It allows smooth evolution to subscriber data center convergence, and can integrate the entire network’ s subscriber data. This lays a solid foundation for FMC network.
Mr. Rizwan, the General Manager of Telenor Pakistan, has repeatedly praised Huawei’ s engineers for their proficiency, extensive knowledge, and highly accurate response to customer-based network needs.
In Islamabad, Lahore, and Karachi, Telenor Pakistan has deployed the Huawei USC with the effect that all call signaling can be done using local access. This optimization reduces Telenor Pakistan’ s long-haul transmission signaling needs by 60%, and greatly enhances its network operation revenue. Looking to the future, the subscriber base will continue growing rapidly and the USC is certain to deliver tremendous value for Telenor Pakistan.
