Secure and seamless IMS services
Many service providers have invested in connection management software to provide ease-of-use to wireless internet services. However, looking forward, seamless wireless internet will be considered as a basic functionality and in order to maintain a competitive offering, new services need to be developed and marketed.
Looking forward, it should also be possible to provide the user with a seamless experience of more advanced services which would enable communication through various media, such as voice, text, pictures and video, or a combination of them.
The service should be adapted to each individual's preference for a consistent experience across multiple access technologies, user devices and geographic locations for business or private use. This is one of the fundamental ideas behind the development of the IP Multimedia Subsystem (IMS).
However, the IMS architecture’s vulnerability to Internet-based security breaches and malicious attack creates tough security challenges for any service provider wanting to leverage from the IMS opportunity. Service providers investing IMS infrastructure are faced with numerous security challenges to be addressed, each of which threaten the ability to deliver valuable IMS applications and associated revenue.
Columbitech provides the service provider with an integrated client solution providing the key functionality required to offer a secure seamless IMS enabled service:
Authentication
Integrated EAP-SIM and EAP-AKA for SIM based authentication.
Privacy
IPSec IKEv2 for 3GPP2 compliance.
Mobility
A combination of MIP/MOBIKE to provide mobility and network transparency for a secure connection.
About IMS
The IP Multimedia Subsystem (IMS) standard defines a generic architecture for offering Voice over IP (VoIP) and multimedia services. It is an internationally recognized standard, specified by the Third Generation Partnership Project (3GPP/3GPP2) and embraced by other standards bodies including ETSI/TISPAN. The standard supports multiple access types including GSM, WCDMA, CDMA2000, wireline broadband access and WLAN.
