This publication presents an entire and accomplished evaluate of 3G UMTS charging servicesEvolving from offline billing of conventional telecommunications, charging for IP providers in cellular networks is difficult; charging convergence is likely one of the significant tendencies within the telecom undefined. complex cellular telecommunications contains information functions with real-time regulate and administration, and calls for a convergent and versatile on-line charging process. Such convergence is vital to mitigate fraud and credits dangers so as to supply extra custom-made details to clients approximately fees and credits restrict controls.Charging for cellular All-IP Telecommunications offers finished and useful insurance of on-line and offline charging in keeping with cellular operator studies, and the most recent efforts undertaken through the UMTS specifications.Key features:Presents an entire review of the telecommunications charging process, together with the evolution from 2G to 3G and all-IP community charging frameworksDiscusses all administration facets regarding charging and billing strategies, with a spotlight at the significant tendencies and advancements in the telecoms industryProvides an outline of the telecom networks similar to PSTN, GSM, UMTS and IMSCovers the recommendations of the telecom charging on cellular prone and the hot applied sciences for enforcing on-line charging method, corresponding to GTP’ and Diameter protocolContains insurance on community nodes and information flows with regards to charging of cellular functions, equivalent to IMS name and content material downloadingExplains the IP-based on-line charging process, protocol info and up to date tendencies in charging for cellular telecom industryThis booklet is a useful source for graduate scholars, telecoms and IP engineers, community provider prone and approach architects. info technologists and networking apparatus brands also will locate this booklet insightful.

If the MS is not assigned a static IP address, then the GGSN is responsible for allocating a dynamic IP address to the MS. Step 2. The GGSN uses the APN to ﬁnd an external network that provides the requested service. In addition, the GGSN may restrict the negotiated QoS proﬁle given its capabilities and the current load. The GGSN generates a GPRS Charging Identiﬁer (GCID) and creates a PDP context associated with the MS. This PDP context records the requested APN, negotiated QoS proﬁle, the GCID and so on.

In mobile data networks, the data bandwidth is limited and the wireless handsets are constrained by small displays, powerless CPUs, limited memory, and awkward interfaces. As a solution to these issues, WAP presents and delivers wireless data services to mobile phones and other wireless terminals [Wap]. In particular, WAP facilitates the implementation of contents and applications on various types of wireless terminals. 8. 8(a)) receives content that is encoded in the compact binary format of Wireless Markup Language (WML).
