Adopting IMS in WiFi Technology
Source: Institut Telecom
IP Multimedia Subsystem which is standardized by 3GPP is an important step to improve the delivery of innovating IPTelephony and Multimedia services to the customers in 3G and B3G networks. However, IMS is almost access independent and multiple access technologies such as UMTS, WiFi, WiMax, xDSL and Cable Technology can benefit from IMS services. In 3GPP Releases 6, architecture for access to 3G services (including IMS services) from WLAN technologies has been standardised and the work is being completed in next releases. The goal of this architecture is to allow the 3G customers to be roamed in WLAN and access to their services in 3G domain.
