Embodiment Construction

[0056] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0057] Embodiments of the present invention provide a dual-stack address management method and a first network element, which are used to indicate which IP address is used between network elements for signaling interaction. Wherein, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve problems are similar, the implementation of the device and the method can be r...

Abstract

Provided are a dual stack address management method, device and first network element, for providing an IP address used for exchanging signaling between specified dual stack network elements. The method comprises: determining, by a first network element, that the first network element and a second network element to be communicated with are dual stack network elements, wherein the dual stack network elements are network elements supporting two types of Internet protocol type addresses; assigning, by the first network element, a higher priority to a transmission path corresponding to a first Internet protocol type address in two types of Internet protocol type addresses and adopting the transmission path to send a session management message to the second network element.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dual-stack address management method and a first network element. Background technique [0002] The International Internet Assigned Numbers Agency (IANA) announced that the global Internet Protocol version 4 (English: Internet Protocol version 4, referred to as: IPv4) addresses have been allocated in early 2011, and the global Internet is gradually moving from IPv4 to Internet Protocol version 6 (English: Internet Protocol version 6). , referred to as: IPv6) transition. [0003] Therefore, operators begin to deploy for each network element in the core network, so that the logical interface of each network element in the core network can support the requirements of IPv6 on the basis of supporting IPv4. As a result, a network element supporting two types of Internet protocol addresses (IPv4 address and IPv6 address) appears in the core network, which is referred to as a d...
