Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] figure 1 It is a structural schematic diagram of a communication system applicable to a method for parsing XML data of SIP signaling according to an embodiment of the present invention.

[0027] like figure 1 As shown, the system includes: a plurality of SIP devices, these SIP devices support the SIP protocol, and establish, modify and terminate two-party or multi-party multimedia sessions on the IP network. By cooperating with RTP / RTCP, SDP, RTSP and other protocols and DNS, the SIP protocol supports two-party or multi-party multimedia sessions for services such as voice, video, data, E-mail, IM, chat, and games. The aforementioned network elements may be mobile terminals or access devices...

Abstract

The invention discloses a method and a device for resolving the extensible markup language (XML) data of session initiation protocol (SIP) signaling. The method comprises the following steps of: receiving the SIP signaling with the XML data by using SIP equipment; determining an XML Schema type corresponding to the XML data; and resolving the XML data according to a data structure of the XML Schema type. By the technical scheme provided by the invention, the problem in the prior art that the SIP equipment is required to perform much repeated resolution and debugging work when processing a great number of XML character streams is solved, the SIP-XML coding and decoding efficiency is further improved, the requirements of coding and decoding on embedded system software and hardware resources are reduced, and the chaotic situation of the conventional SIP-XML development is normalized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for analyzing XML data of SIP signaling. Background technique [0002] SIP (Session Initiation Protocol) protocol is a protocol on multi-party multimedia communication formulated by IETF, which is used to establish, modify and terminate two-party or multi-party multimedia sessions on the IP network. By cooperating with RTP / RTCP, SDP, RTSP and other protocols and DNS, the SIP protocol supports two-party or multi-party multimedia sessions for services such as voice, video, data, E-mail, IM, chat, and games. With the development of technology and the gradual unification among manufacturers, the SIP protocol has become one of the most important communication protocols in the next generation network (NGN). [0003] XML (Extensible Markup Language) is a data storage language defined by W3C, which uses a series of simple tags to describe data. Applying XML langu...
