IPv6 terminal address generation and parsing method in communication network

Abstract

This invention relates to communication network terminal IPv6 address generation and analysis method, which comprises the following steps: the distributing IPv6 address network point sending IPv6 address front information; using terminal receives message to determining the said user terminal identity label to set into IPv6 address back sixty four bits. The analysis method comprises the steps of network point receives user terminal message to get message IPv6 address and extracting back sixty four as only one label number.

Description

technical field [0001] The present invention relates to a method for generating and analyzing an IPv6 address of a terminal in a communication network, in particular to a method for generating an IPv6 address in which an identification number of a terminal is configured in the last 64 bits of the IPv6 address, and an IPv6 address based on the generating method parsing method. Background technique [0002] In a mobile communication network, when a user terminal (UE) wants to access an IP network, a node on the network side needs to assign an IP address to the UE, and the UE can access the IP network only after obtaining the IP address. In the currently used mobile communication network, GGSN (Gateway GPRS Supporting Node, Gateway GPRS Supporting Node) is responsible for assigning IP addresses to UEs. For IPv4 networks, when UEs want to access IP networks, they initiate requests to GGSN. The returned confirmation message carries the IPv4 address allocated for the UE. In orde...

Problems solved by technology

[0008] 2. There are many failure points for UE to obtain IPv6 address prefix or IPv4 address

[0011] 5. The IP packets of the UE accessing the IP network must pass through the WAP gateway, which limits the networking of services

With more and more services that are no longer based on the WAP protocol and have no relationship with the WAP gateway, this limitation becomes more and more unreasonable

This limitation also makes WAP gateway become the bottleneck of network service expansion

[0012] 6. Regarding the generation method of the IPv6 address in the prior art, the last 64 bits of the IPv6 address are not fully utilized, resulting in a huge waste of resources of the IPv6 address itself

[0013] 7. In the prior art, GGSN needs to assign different IPv6 address prefixes to different mobile terminals, and each mobile terminal will consume 2 64 address space, the waste of address resources is very serious

Although the IPv6 address space is huge, it is still difficult for mobile communication operators to obtain a large IPv6 address space from the address allocation agency. It is already quite difficult to meet the current mobile terminal address requirements. With the development and commercialization of new technologies, insufficient addresses will still become an important problem that plagues mobile communication operators
