Telecom technology terminology: Wireless Value-Added Technology SIP

Today, wireless service providers have been seeking cheaper voice services to maintain their market share. Obviously, the secret to surpassing competitors is to launch some attractive services with additional charges. However, existing technologies such as SMS need the same cost model as voice. Therefore, wireless service providers focus on the commercial technology of Session Initiation Protocol (SIP. SIP is an application standard in the 3G era, but in today's commercial applications, it can also bring unprecedented killer applications to wireless service providers.

What is SIP

SIP is a text-based protocol similar to HTTP. What makes sense is that SIP can reduce the development time of applications, especially advanced applications. Moreover, because of the similarities between HTTP and SIP, many people are preparing to use SIP to generate applications, including Web designers. This is the first time that wireless service providers have the opportunity to allow a large number of talented Web designers to design valuable Internet applications for their users, and for the first time that Web designers can truly understand and operate wireless communication protocols. This is easy to use and can create immediate increases in revenue. These reasons are enough for operators to pay high attention to SIP now. Moreover, because ipprotocol-based SIP uses an IP network, fixed network operators will gradually realize the far-reaching significance of the SIP Technology for them.

Implementation of SIP

Although the profound meaning behind the SIP-based application is still difficult to understand, it is certain that it can completely change the mobile communication mode, it facilitates access to the next generation of services. Now, SIP has been selected as the multimedia R5 standard in 3G mobile communication by the 3GPP standard organization, and the R5 standard will become more and more important as the 3G deployment begins. SIP is a 5th-layer text-based protocol, which is at the same level as HTTP, FTP, and SMTP. Therefore, SIP can be integrated into any HTTP webpage, which helps speed up the implementation of SIP.
