Contact Us for a detailed course description.
This course provides a clear and logically organized tour of the 3GPP UMTS 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.
Who would benefit
Those requiring a comprehensive understanding of UMTS core network architecture, interfaces, protocols and operation, including the Release 4 circuit switched core network, the packet switched core network, associated functions such as security, charging, signalling protocols and location based services.
Familiarity with the architecture and general operation of a UMTS network is beneficial. Some knowledge of IP and the OSI seven-layer model will also be advantageous.
Topic areas include
- UMTS core network architectures
- Asynchronous Transfer Mode (ATM)
- Iu protocol
- Circuit-switched core network procedures
- Packet-switched core network functionality
- Mobility management
- Interworking with 2G, 4G and WLAN
- Multimedia Messaging Service (MMS)
- IN and CAMEL
- Location Services (LCS)
- Security functions
- Evolution to the Evolved Packet Core (EPC)
