Embodiment Construction

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0056] Based on the prior art, the encoding and decoding process cannot adapt to conditions such as different applications, different interfaces, different Diameter messages, different manufacturer definitions, different versions, etc., resulting in inflexible message definitions and easy conflicts. The present invention provides a free Adapt to the encoding / decoding method and device. The core idea is to define the corresponding runtime ...

Abstract

The invention discloses a self-adaptive coding / decoding method and a self-adaptive coding / decoding device. The coding method comprises the following steps: receiving relevant application information to be coded, reading a message structure of the relevant application information and obtaining relevant information of AVP; searching a regenerated run-time encoding table according to the relevant information of the AVP and obtaining AVP configuration information corresponding to the relevant information of the AVP; carrying out legality validation on the relevant information of the AVP according to the AVP configuration information; and organizing and generating a Diameter message code stream according to the relevant application information and the relevant information of the AVP when the relevant information of the AVP is legal. By adopting the method, the separation is realized through coding and decoding configuration data and specific application interfaces, the protocol expansibility is increased, and meanwhile, the run-time encoding table can be dynamically obtained and adjusted so as to satisfy the demands of different operators, different application interfaces and the like.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for adaptive encoding / decoding. Background technique [0002] The Diameter protocol has developed into the next-generation AAA (Authentication, Authorization, Accounting, identity verification, authorization, and statistics) protocol standard based on the Radius protocol, and is being used more and more widely. [0003] The Diameter protocol suite includes the basic Diameter protocol and some extended application protocols, such as NAS (Network Access Server) protocol, EAP (Extensible Authentication Protocol, extensible authentication) protocol, MIP (Mobile IP, mobile IP) protocol, CMS ( CryptographicMessage Syntax) protocol, SIP (session initiation protocol, session initiation protocol) application protocol, etc. In addition, each manufacturer is allowed to extend the protocol AVP as needed. [0004] Due to the existence of various extended applicatio...
