Could VoIP Help the Mobile Networks?

DIAMETER method is an expansion of RADIUS which will be meant to provide an Authentication, Authorization and Accounting (Triple-A) structure for programs such as for instance Network access or IP-mobility.

Triple-A Size is the preferred option around their counterpart RADIUS project and is being generally adopted in with world markets today. Due to potential benefits of length over RADIUS and intensive functions to cater the 3GPP previous produces and new LTE requirements along with other process like IMS, length is advised in the LTE specification as an single solutions.

The 3GPP SAE (Third Era Collaboration Project Program Architecture Evolution) connected requirements are very nearly absolutely described except for a few detailed specifications. Among them is the PDN GW (Packet Data Network Gateway) collection for non-3GPP IP (Internet Protocol) access.

At present, the PDN GW selection purpose interacts ubiquiti the 3GPP Triple-A (Authentication, Authorization and Accounting) machine or the 3GPP Triple-A proxy and employs subscriber data given by the HSS (Home Subscriber Server) to the 3GPP Triple-A server.

All through the original authorization, PDN GW variety data for each of the fell PDNs is delivered to the non-3GPP access system. The PDN GW variety information includes an IP handle of a PDN GW and an APN (Access Point Name).

Cellular communities have adopted many systems during their development including GSM, GPRS/EDGE and WCDMA/HSDPA. More over, long-term evolution (LTE) will make their debut before long on the worldwide complex stage. The inception of LTE/SAE (system structure evolution) system structure can convert the charging structure as follows:

Firstly, the LTE network environment needs that operators use a network entity to discover and obtain support traffic data, and apply charging get a handle on by getting together with the online/offline receiving system.

Secondly, LTE/SAE architecture supports access for LTE and 2.5G/3G systems, and also for non 3GPP accessibility setting radio programs such as for example WLAN and WiMAX. LTE/SAE structure should allow person devices'network handover functions which are reinforced by the receiving system.

The 3GPP SAE adopts package information network gate way (PDN-GW) between the SAE primary network and the PDN, which functions as a data control gateway under different accessibility modes. As a primary system key control node, the PDN-GW is comparable to the GPRS network's GGSN in that it can detect company knowledge moves and implement traffic collection. The process is associated with the online/offline receiving system through the Ro/Rf interface.
