By knowing the importance of the CORE Network, the main objective of an audit service at this level is reviewing the design and planning of the network analyzing the signaling and switching infrastructure, the network architecture, the profile and the traffic matrix, routing tables and, signaling links. Throughout the analysis process of the audit of the CORE network, our consultants study the performance of the infrastructure of the signaling and switching network, including in the case of GSM the following:

• VMSC Layer (legacy / soft switch)
• GMSCn/ TMSC layer
• Signaling & traffic Trunks GOS
• HLR
• GPRS

The parameters that are included, but are not limited to, are the following:

• MSC GoS    Inter/Intra MSC HO success
• Processor load   Technical completion rate
• Actual usage of node   BHCA traffic and traffic profile
• MSC availability    Interconnect Blocking rate
