The Universal Mobile Telecommunications System (UMTS) is a globally significant third-generation (3G) mobile cellular radio system. It provides a natural progression path for all GSM/GPRS networks and is therefore rapidly becoming the most widely adopted 3G technology globally. The use of UMTS and HSPA enables mobile-network operators to offer advanced multimedia-based services through the capability to support higher bit rates and, importantly, a much more flexible radio interface compared with 2G technologies.
These new service capabilities make additional market sectors accessible for new and existing network operators alike. UMTS also brings improved quality, more capacity and more efficient network operation, in terms of both the radio interface and the core network. The courses in this category cover all aspects of UMTS and HSPA operation from the radio air interface through to the core network including planning and optimization. There are courses that would suit engineers who need to add to their existing knowledge on the subject and those who are completely new to this technology.
This course provides a clear and logically organized tour of the current independent 3GPP Release 4 circuit switched- and packet switched core network domains. The course describes the operation of the main core network protocols and outlines the evolutionary path towards an all IP based network. The functions of the various interfaces are explained including those towards the Evolved Packet Core (EPC). References are made to the latest releases of 3GPP specifications throughout the course.
This is followed by an introduction to the all IP core network evolution path based on the IP Multimedia Subsystem (IMS) and an explanation of the Evolved Packet Core (EPC) and underlying protocols for core network interfaces.
