What IP address is used in 3G data service

A large number of IP addresses are required when addressing mobile data services. The current public IPv4 address has become a scarce resource, so mobile data operators are faced with the problem of choosing the address between IPV6 and private IPv4 addresses. At present, the industry generally believe that the 3G should be used IPV6 address. In addition, the choice of IPV6 is also relatively small with its memory and processing overhead and is ideal for mobile terminal devices.

Although there have been some positive signals for using IPV6, the fact that IPV6 is in the mobile data field is not ideal. Many mobile data carriers, especially those originating from traditional telecoms operators, find IPv6 more difficult to deploy, leading to higher infrastructure costs. In addition, with the current IPV4-based Internet interoperability, not only is faced with the use of private IPv4 address all the problems faced, but also more complex and difficult to control.

Whether in the mobile data field or in the traditional Internet domain, IPV6 is currently facing a dilemma, in part because of the IPV6 technology itself, such as network products, operating systems, applications and standardization support, The main reason is that the advantages of IPV6 in the following areas are still not fully reflected:

Quality of service (QoS) guarantee. IPV6 does have a certain improvement in performance, but this is not the same thing as the so-called QoS guarantee currently studied. Currently, the main solution for Ipqos is DiffServ, InterServ, and Multiprotocol tag switching (MPLS), which apply to both IPV4 and IPV6. In other words, IPV6 will use the same technology as IPV4 to solve the QoS problem, not because of the use of IPV6, the quality of service will be guaranteed.

Security assurances. Both IPV4 and IPV6 use the Ipsee protocol to provide security assurances, except that the IPV4 requirements for ipsee are optional and IPv6 is mandatory for ipsee. However, the mandatory requirements of IPV6 for Ipsee are only implemented, not necessarily used in application, because one is not necessary, and the other is to use will have a significant impact on performance. So from this point of view the security of the two is almost equivalent, there is no possibility that IPV6 will be safer than IPv4.

Better mobility support. It should not be denied that IPV6 support for mobility (mobile IP) is better than IPv4, but it should be noted that only if the MOBILEIP business has real market application value, it is possible to explore what kind of support would be better? Mobileip from the birth has still not been widely used, the root cause is the lack of "killerapplication (Killer Application)", which means that there is no such as e-mail, www, as a great impetus to the development of the Internet applications, must or preferably use MOBILEIP to support. There may be such applications in the future (such as the popularization of 3G), but there is no, at least not obvious or no large-scale popularization.
