Introduction of wimax and Triple-A Diameter
Although 3G technologies produce significantly higher bit prices than 2G technologies, there is nonetheless a fantastic opportunity for wireless companies to pay attention to the need for “wireless broadband”. There’s an chance from a growing number of consumers and business experts who are demanding the same experience and programs that they love on a set wire point relationship over wireless – – anyplace, any content, stationary or mobile.
The solution is wimax, (3GPP Long Term Evolution), the next-generation system beyond 3G. In addition to permitting set to cell migrations of Web applications including Voice over IP (VoIP), video streaming, songs downloading, mobile TV and several others, LTE sites will also provide the ability to support in demand for connectivity from the new generation of consumer devices designed to these new mobile programs.
SIZE protocol is an extension of RADIUS which is meant to supply an Authentication, Authorization and Accounting (Triple – A) framework for programs such as Network access or IP – mobility.
Now unified Triple – A solution Design in LTE Triple – A Diameter is the preferred solution over its equal RADIUS protocol and it is being widely adopted in with globe markets.
Because of possible benefits of diameter over RADIUS and substantial features to accommodate the 3GPP old releases and fresh LTE specifications in addition to other program like IMS, diameter is recommended in the wimax standards as an unified solutions.
Triple-A for 3GPP System Accessibility
The 3GPP Triple-A server is found within the 3GPP HPLMN (Residence Public Land Mobile Systems). It works the Triple – A functions and might also behave as an Triple – A proxy server. For WLAN 3GPP IP Entry it gives authority, policy administration and routing information to the PDG, WAG and WLAN AN. For charging, the 3GPP Triple-A Server:
Triple-A for Non-3GPP Method Entry
The 3GPP SAE (Third Generation Collaboration Project System Structures Evolution) related specifications are nearly entirely defined except for some detailed specifications. Among them is the PDN GW (Packet Data System Gateway) selection for non-3GPP IP (Internet Protocol) entry.
At present, the PDN GW selection function interacts with the 3GPP Triple-A (Authentication, Authorization and Sales) server or the 3GPP Triple-A proxy and utilizes subscriber information provided by the HSS (Home Client Server) for the 3GPP Triple-A machine.
Throughout the first authority, PDN GW selection information for each of the subscribed PDNs is returned to the non-3GPP access system. The PDN GW choice information contains an IP address of the PDN GW and an APN (Access Point Name).
Moreover, long-term evolution (4g) will make its advent before long on the world-wide technical position. LTE/SAE design should permit user terminals’ network handover procedures which are backed by the billing method.
