How to integrate IPv6 with Mobile Communication

The continuous and rapid development of the Internet has brought many problems, such as IP address depletion, network security, QoS, and mobile features. The proposal of IPv6 technology can solve the above problems of the Internet. The most prominent advantage of IPv6 is that it greatly expands the address space, restores the end-to-end connection function that was originally lost due to address limitations, and provides basic conditions for Internet popularization and further development. Deploying and implementing IPV6 in the network brings many advantages to the network. After IPv6 is integrated with mobile communication, it can effectively simplify business processes, improve efficiency, and ensure the development of some real-time services.

Address capacity expansion

IPv6 increases the size of an IP address from 32 to 128 bits. It supports more address levels, larger nodes, and simpler automatic configuration of addresses. IPv6 supports Neighbor Discovery, ND) and automatic address configuration. The above two technologies can be assigned to a large number of wireless mobile terminals with fixed global IP addresses, so as to avoid the lack of NAT-PT and restrictions, so that a variety of mobile terminals quickly, convenient access to the mobile communication network, so that "always online" has become possible, this makes it possible to carry out various end-to-end applications and services, such as games, voice, multimedia information, and chat, which do not require server support.
Hierarchical address Structure

IPv6 uses a hierarchical address structure. Its advantages are: first, it reduces the number of Route tables. Second, it is well-defined and easy to use the ND protocol for automatic Address Configuration and mobile monitoring. Third, direct communication can be achieved between mobile nodes, which enables point-to-point voice and interactive and real-time multimedia communication in mobile communications, and Internet-based "push" services all have very important technical support.
Simplified Header Format
The IPv6 Header Format is concise, efficient, and flexible. Some IPv4 header fields are deleted or become optional fields, which reduces the overhead of packet processing and the bandwidth occupied by IPv6 headers. For wireless communications that require bandwidth and wireless resources, this feature makes sense in packet data transmission to reduce network transmission latency and ensure high-speed data rates.
Data Flow Label capability

For the increasing number of multimedia data communication and real-time communication, there are two fields in IPv6's first Technical School: "Traffic type" Traffic Class) and "Flow Label" Flow Label, in order to ensure the different service quality requirements of users in the future, this laid the foundation for the implementation of large bandwidth data communication on mobile devices. The stream tag domain can be effectively applied to the Intserv/RSVP service model, while the traffic type domain can define different types of traffic in Differentiated Services, similar to IPv4 TOS. How to use these domains depends on the current research development and application requirements. However, they all provide the possibility of hierarchical transmission of real-time data.
Authentication and confidentiality
In consideration of Security, two extension headers are added in IPv6: ID Authentication Header AH, Authentication Header) and encapsulation Security net load (ESP, Encapsulating Security Payload) to ensure the security and reliability of the transmitted data. AH and ESP support two conversion modes: tunnel mode and network protocol conversion mode. The IP Security in tunneling mode provides encrypted connections between gateways and forms a virtual private network on the public Internet. The IP Security in the network protocol conversion mode is used for the encrypted connection between the mobile host and the corresponding access network server. The encrypted data link is established on the Internet.
IPv6 progress in 3G
With the proposal of the 3G full IP Solution, IPv6 and mobile communication integration have become common basic protocols. Mobile IPv6 integrates IPv6 with Mobile communication to provide ubiquitous and "always online" connections. The following describes the application and progress of IPv6 in terms of mobile terminals, access networks, and core networks based on the 3GPP specifications.
Terminal

TS 27060: Packet domain; Mobile StationMS) supporting Packet Switched services, version 5. This specification defines the IP-based voice and non-voice data services supported by terminals. It describes the protocols and order specifications that support packet exchange services. For details, see the 3GPP TS 22.060 and 3GPP TS 23.060 specifications. The Specification defines the application of IPv6 technology in terminals.
The allocation standard is defined in the 3GPP TS23.060 standard. The IPv6 address and user plane signaling description are dynamically configured in the 3GPP TS 29.061 standard; for the IPv6 address support, allocation, and connection to other networks of UE, see section 23.221 of 3GPP TS 5th V6.0.0: IP addressing.
Access Network
The 3GPP standards for access networks are mainly 25 series. An important specification is TR 25933 v5.3.0: IP transport in UTRANRelease 5). This specification analyzes the IPv6 technology used as the theoretical basis for Transmission Technology in UTRAN, and defines and describes IP Technology IPv6) the application in UTRAN includes IP Address Transmission and routing on the user plane and control plane, interconnection and interfaces with other networks, and specific technical details of IPv6 in Node B and RNC entities. The MPLS-based transmission solution is also defined in this specification.
It should be noted that this specification is still inconclusive and has been in the upgrade and development stage with the development of technology and business requirements.
Core Network
3GPP TR23.922: Architecture for an All IP network, version 2000. This specification defines the full IP core network using the Packet Exchange Technology and IP technology in 3G systems, as well as the capabilities that can support real-time and non-real-time services, including voice, data, and real-time multimedia, services supported by other network elements). Multiple Access networks include UTRAN and ERAN. packet transmission using the IP protocol and IP Client terminals. In short, version 2000 is version 4, in the PS domain, you can already provide the same services as in the CS domain.
