We have IPv6 running on a number of Mobil...Hi, all<br /><br />We have IPv6 running on a number of Mobile operators in the world today, both in operations and in test. All of the operational networks use Ericsson SGSN/GGSN and supports IPv4 PDP and IPv6 PDP. These PDP's can terminate in APN's that supports both IPv4 and IPv6. Later this year there will be support for a dual stack PDP, which also impliese that terminals supporting this will only use one RAB (Radio Access Bearer), therefore saving valueable radio resources.<br />If You live e.g. in Sweden, or Slovenia some operators have native support in the Mobile network.<br />The biggest issue with full native IPv6 support, is the application still only running on IPv4 servers. Therefore the operator need an translation Gateway (e.g. ALG64/NAT64/DNS64) to secure that all services (Either in IPv4 or IPv6 domain) are reachable.<br />Beside the pure Gi/SGi interface issues, the operator also need to support settings in HSS/HLR (2 bits for Pure IPv4, Pure IPv6 or dual stack) to control the end user capabilities. This also implies that You need to have support in the HLR/HSS front-end call CCS (Customer Care System).<br />Beside this normally all operators wants to be able to bill the traffic, which means that the Billing system must support both Dual stack and IPv6 CDR's. Some operators have a good Billing system, and some have home-made systems (Leading to redesign or rewrite the software - Reluctance to do it because of "small investment").<br />To this You also have operators running DPI solutions to control the traffic, and those have normally some issues with IPv6 due to the bit-width that's coming and also the extension headers that makes IPv6 a little more difficult to handle.<br /><br />IPv6 are not hard to do, it takes a very short time to implement. But the prepartion needs to take time, so the operators doesn't end up in an architectural mess later (As in IPv4 case).<br /><br />Best regardsUnknownhttps://www.blogger.com/profile/17650235842254008033noreply@blogger.com
