Embodiment Construction

[0020] Considering that current IMS network elements generally support IPv4 and IPv6 dual stacks, in actual networking, the difference in IP version type is mainly caused by the different IP versions of the access network. Therefore, under this condition, there is no need to consider signaling plane intercommunication, but it is necessary to reduce the conversion points of user plane intercommunication as much as possible.

[0021] figure 2 It is a logical structural diagram of a system that adopts a translation application server TrAS as a translation control unit and implements IP address translation by controlling the IMS-ALG according to an embodiment of the present invention. Such as figure 2 As shown, the above system includes a calling side and a called side. In the present invention, the IMS core network element supports IPv4 and IPv6 dual stacks, and the terminal uses different IP address versions for the calling side and the called side due to different access ne...

Abstract

This invention discloses a method for mutual communicating between the terminal user surfaces of Ipv4 and Ipv6 of IMS including: 1, a calling terminal starts up a session request to a called terminal based SIP, 2, a service call session control function unit of the called terminal receives said session request and transfers it a transformation control unit, 3, the transformation control unit controls the transformation to finish the conversion of the address edition of the calling terminal and the called terminal IP. In this invention, an applied server logic entity is taken as a conversion unit and a signed data trigger mode is applied to enable the flows of IP edition conversion and that of code ¿Cdecode transformation completely the same.

Description

technical field [0001] The present invention relates to an intercommunication method between different protocols of the network, in particular to a method for realizing the intercommunication between IPv4 and IPv6 of an IP Multimedia Subsystem (IMS) terminal user plane by inserting a conversion point of the user plane. Background technique [0002] The IMS network is an all-IP service network architecture defined by 3GPP and based on the Session Initiation Protocol (SIP). Deploying IMS on an IP network must consider the allocation of IP addresses for terminals and network devices in the IMS network. There are currently two types of IP addresses, namely IPv4 addresses and IPv6 addresses. [0003] According to the agreement of the 3GPP R5 standard, the IMS network side adopts the IPv6 version. In the long run, it is a trend that IPv6 gradually replaces IPv4. However, in a certain period of time, IPv4 and IPv6 will still coexist. In the R6 protocol, the IMS network supports...
