Together with dynamic expansion of mobile networks, the services offered to subscribers also evolve. Initially mobile networks were primarily focused on a single service – voice call, that mainly contributed to the operator’s revenue. Later, more services were introduced. It enabled creation of sophisticated offer, attractive for a wider subscriber base. As a consequence, number of subscribers rapidly increased. Enriched service offering created alternative sources of revenue. A very good example is SMS service, especially popular among the younger users. Another milestone in mobile network evolution was the introduction of mobile access to the Internet based on packet data services. Actually, packet services are the main drivers behind the recent mobile networks evolution based on UMTS, HSPA or LTE technologies. On the other hand, opening to the Internet has also negative effects. Nowadays, mobile subscribers have access to multitude of services offered by Internet providers. For these providers, often called “Over The Top”, the main source of revenue are advertisements. In order to attract as many users as possible, they develop very sophisticated services like voice communicators, chat applications etc. Moreover, these applications are offered free-of-charge. As a consequence, mobile subscribers are reluctant to pay for services, that constitute a large percentage of operator’s revenue share. Therefore, revenues of mobile telecom providers have been falling over the last years. In order to counteract this trend, completely new, innovative approach to service creation must be introduced. This is a subject of this course. Currently, mobile operators have the possibility to create almost unlimited service offerings, that meet individual subscriber needs. It is possible thanks to Policy and Charging Control (PCC) functionality. This architecture discussed during the lecture enables a precise control of packet traffic and accurate charging of individual services accessed by the users. The training presents historical background and subsequent evolution of the PCC system. Functionality of PCC components is discussed. New features available in each PCC release are presented. Required modification in the infrastructure and resulting benefits for the operator are investigated. Examples of service offerings available due to implementation of the PCC system are presented. For better understanding of the PCC functions, basic traffic cases are analysed.
The course is intended for participants with no experience in PCC architecture. It is dedicated to technical as well as non-technical staff. The content should help the representatives of marketing and VAS departments to understand the multitude of new service offerings and charging models available thanks to the PCC system. It should be also interesting for the engineers working with the core network and charging, but not familiar with this new system.
Basic telecommunication knowledge and eagerness to become familiar with the newest solution that will become crucial in future network evolution, service implementation and revenue assurance.
