Analysis of Mobile IPv6 data transmission and the main problems - mobile, IPv6, data transmission -


Article by hi joiney


Many parts of the world of mobile data services revenue in total revenue share of mobile services has more than 30%, mobile networks and the Internet is the depth of integration of 3G services in the development of very prominent feature. Many current main international operators of value added services, the mobile download business is very important. For example, KDDI in Japan through such business has been on a good income. Mobile E-mail, mobile blog, mobile podcasts (video sharing), mobile IM and other services are also very popular.

Hutchison Whampoa launched its HSDPA network in the X-Series, in the form of monthly billing system for customers, including VoIP, mobile IM, mobile search, mobile auction the latest Internet applications, has introduced Some new applications, such as Mobile TV Business, video sharing services, etc..

Representation of mobile Web2.0 Mobile Internet applications for mobile Communicate And the integration of the Internet, but mobile Internet is not equal to "mobile network + internet" because the characteristics of its own mobile network will form the traditional use of the Internet has brought great changes. For example, mobility of mobile terminal location can be directly generating a location-based applications. Meanwhile, the small size of mobile terminals, low processing power and wireless channel restrictions, making Internet content and application forms must be able to adapt to the requirements of mobile networks. In recent years, with the capacity of 3G networks and Web2.0 to enhance the development of mobile Web2.0 development gathered pace. Mobile Web2.0 greatly enhanced the interaction between value-added services, and more thoroughly reflect the participation of all, the core purpose to build the Internet.

IPv6 standards mature and as the trial run, in the 3G license issuance, the use of mobile IP technology to provide anytime, anywhere mobile data communications services, has become an urgent task operators. Implementation of Mobile IP based

And compared to existing mobile communication systems, 3G network in the core network using IP packet switching and a comprehensive control technology, has a higher spectrum efficiency, communications, more capacity, better communication quality, higher data rates and global roaming, and can provide many new services, including Electronic Pay, location query, securities banking, electronic news and other interactive services, video news TV News, video conferencing, video telephony, and wireless video services, and the simultaneous transmission of multimedia services.

Mobile IP does not refer to the IP mobile communication system technology, but to the mobile host can move the state, in different locations access to the Internet, including access through the mobile communication network, including through the fixed network or local area network access.

Mobile IP security key technology is how effectively will be sent to the user's data transmitted from the ownership of the IP network to the user the current access network. Its characteristics is that when the host access point from a new IP network access after that it will be registered to the home network. After completion of the registration operation, if the data needs to be sent to the user, the home network technology through the tunnel the data forwarded to the user's current access network.

Mobile IPv6 data transfer Mobile IPv6 node via the Internet Control Message Protocol (ICMP) router search information to determine their position. IPv6 router searches for two messages: Router Broadcasting And the router requests. Broadcasting from the home router Proxy And routers connected them periodically broadcasting link, router request is by those who do not have enough patience to wait for the next broadcast packet sent to the router the mobile node sent.

Mobile node sends data packets using a special mechanism is directly routed to the destination. However, when there is the entrance of the filter, the mobile node can send packets through the home agent tunnel, the tunnel's source address for the mobile node's care-of address.
