this paper outlines the infrastructure required for a penetration testing suite centered around the cellular call control protocol called Diameter. A brief description of Diameter is given along with the basic equipment and design requirements to conduct the testing. Diameter, Wireless Security, Penetration Testing, SIP, SS7

In the present Mobile Telecommunications scenario, the transmission of SS7 signalling on traditional TDM circuits is evolving to a SS7 over IP network (SoIP) solution, due to the continuous efficiency research in optimizing transmission and to the continuous goal of cost reduction. Some operators are using SoIP network in a national environment, while international SoIP networks are going to be...

Signalling protocols are responsible for fundamental tasks such as initiating and terminating communication identifying the state of in telecommunication core networks. System No. 7 (SS7), Diameter, GPRS Tunneling Protocol (GTP) main used 2G to 4G, while 5G uses standard Internet its signalling. Despite their distinct features, especially security guarantees, they most vulnerable attacks roamin...

This paper focuses on deployment of voice over the Internet for the customers of a global services provider which needed to extend cost-effectively the portfolio of enhanced voice services including unified messaging, post paid and prepaid calling card services along with related validation, billing and payment systems. Key-words: VoIP, Internet, SS7, Compression, QoS

SS7 is a signaling system for the public switched telephone network (PSTN) [1,2,3]. SS7 network transports call setup, teardown messages, database queries, trunk status, instructions for remote phone switches and so on, in fact it acts as a glue for the circuit switched networks. Before the deregulation act it was envisioned as a closed community network. After the deregulation, landscape has c...

The global Signalling System No. 7 (SS7) network protocol standard has been developed and regulated based only on trusted partner networks. SS7 by design neither secures the communication channel nor verifies entire peers. used in telecommunications deficiencies that include verification of actual subscribers, precise location, subscriber’s belonging to a network, absence illegitimate message f...

We propose and estimate a novel transport layer mobility management scheme: Seamless IP diversity based Generalized Mobility Architecture (SIGMA). SIGMA provides seamless handover for mobile hosts and is based on Stream Control Transmission Protocol (SCTP), which is a new dependable transport protocol to transport SS7 signaling messages over IP network. We also show that our handover scheme can...
