“…i . i k Pilot has defined several test cases with the purpose of verifying any-to-any basic service functionality for successful and unsuccessful calls across the NGN configuration, using both G.711 and G.729 codecs [2]. The following topics can be considered in test cases: Table 1, you can see the signaling flow of a successfully connection between a SIP-based terminal and a terminal that has been connected to an Access Gateway (AG).…”

In this paper we have introduced a testbed for interoperability basic call tests in Next Generation Networks (NGN). This testbed can be used for two different solutions, one solution is used for evaluation of call servers interoperability and the other for evaluation of interoperability between the call server of a vendor and NGN equipments of the other vendors. Finally, we found out that most problems are related to implementation of NGN protocols. Inaccuracy in Megaco/H.248 and SIGTRAN implementation caused are those of importance.

“…As internetworking of different devices is an outstanding issue in every service delivery system [11], the set design environment is proposed to be capable of supporting the compatibility of different devices together. Accordingly, all solutions and systems have been tested in both single-vendor and multi-vendor architectures.…”

In this paper the test methodology has been expanded for evaluation of DSL broadband services. This is a new strategy for testing and considering different aspects of test. This strategy can precisely test various features of DSL broadband equipment and services which can be delivered by them in terms of different aspects of testing such as functionality, performance, conformance, etc. It was practically executed over a designed testbed in Iran Telecommunications Research Center (ITRC) where a lab named NGN Pilot exists. The introduced strategy has a hierarchical structure from the topmost level of testing including different categories to the bottommost level including detailed test topics and test cases. This paper elaborates how the strategy was designed and how it can be applied to a desired environment to compare different DSL scenarios with each other. The strategy can then be used by a service provider to help deciding which solutions can achieve the best outcome.

“…So, it is difficult to share information between systems. Facing the "silo problem" [2,3] network management systems, telecom operators have to take the way of "swivel chair" [4] to manage the telecommunication networks. The way of "swivel chair" is not only costly and inefficient, but also difficult to make full use of OSS operation data.…”

In order to build the information model of the new generation of Operation Support System (OSS), we firstly point out that OSS is currently entering the era of big data management, and the Telco Operators are now facing big challenges. We then summarize the difficulties to build the OSS unified information model. After that, the paper surveys the existing information models, and modelling methodologies for OSS, and analyzes their applicability, advantages, as well as disadvantages. Finally, the idea of building the OSS unified information model is put forward. Moreover, the modelling idea has been applied in practice.
