IPTV Service over IP Multimedia Subsystem
Article
Full-text available
IP Multimedia services provide a dynamic combination of voice, video, messaging, data, etc. within the same session. By increasing the number of basic applications and the media that it is possible to combine, it is possible to increase the number of services offered to the end users, and thus to enrich the inter-personal communication experience....

Moving voice traffic from circuit-switched domain to packet-switched domain seems to be the only rational way to improve quality of experience. Voice over Long-Term Evolution (VoLTE) is a technology that enables transmission of voice calls over LTE network by using IP Multimedia Subsystem (IMS). VoLTE is bandwidth efficient and offer better speech...

  • Dec 2009
The challenge of providing seamless services to the end users moving from one network area to another has become a critical issue for the operators to focus on. Intersystem handover can be a solution whilst to maintain the continuation of an on-going session, IP management is a key issue. Henceforth, to resolve the intersystem handover, both applic...
