Concentrating on the longer term community structure and its major ideas, Converging NGN Wireline and cellular 3G Networks with IMS offers a accomplished view of the equipment, features, community parts, and the interfaces between them that allow the construction of a provider agnostic and entry agnostic consultation keep an eye on layer in accordance with the IMS criteria.

After an creation to IMS rules with industry tendencies, technological thoughts, migration concerns, and international criteria, the publication describes converged consultation regulate and multimedia dealing with with identity administration, carrier profiles, and occasion and purposes triggering in addition to admission approaches for various sorts of entry networks. next chapters take on the all-important points of IP charging mechanisms, service-based caliber of carrier, defense, border regulate, and legacy prone, allowing a radical appreciation of the whole community requisites. anyplace attainable, the writer issues out the convergence of criteria and information various requisites and terminology for TISPAN and 3GPP.

Delivering deep perception into the position of IMS in fastened line and cellular networks, this booklet explains the recent applied sciences from thoughts to specific thoughts to provide a transparent knowing of the way the subsequent iteration of converged verbal exchange should be completed with controlled caliber, protection, and chargeability.

Example text

Traditional Fixed-line services are associated only with a particular circuit line. 2G Mobile phones also have services associated directly with the SIM card, not the user, and therefore offer no service mobility across devices. , personal address book). Many services might be very useful when they become available in a variety of places and terminals. For example, a Pre-pay service can apply to 2G Mobile, IMS Mobile, laptop VoIP, and even residential lines, with a single credit account. Service interfaces and presentations can vary according to the terminal capabilities.

The user’s application data can be stored on the Home AS, and is reached via service interaction between the two ASs. This is typical of Distributed Messaging service and Internet-style mash-up services. A local AS is invoked but it connects to another AS in the Home Network. This option allows for regional variations while charging is still performed by the Home Network. In this scenario, there must be a close relationship between the operators and a standard interface between the applications, such as found in SMS messaging services.

The equivalent concept in wireline (Fixed line) is the Virtual Home Environment (VHE). 9 IMS inter-network connectivity. applications are made available, regardless of what network is carrying the signals. Implementing this requires standard interfaces that allow signaling to cross over business boundaries toward the Home Network, much like the 3G Mobile network. Hence, only one converged standard (IMS) has gone forward. 9 shows Caller A in a Visited Network IMS 1. By agreement, Caller A is recognized as a subscriber of IMS 2, therefore, the signaling is forwarded to the Home Network for authentication.
