RCATSONE Voice Quality - Service Value Package

Validating the end users experience of voice quality services

The Voice Quality Service Value Package (SVP) is an automated, distributed solution to proactively test voice quality over a variety of call scenarios across various locations within an operator’s network. For each test, the VQ SVP validates end-to-end voice calls over the air interface and through the operator’s network. It then assesses the speech quality of the voice call using industry-standard ITU algorithms that specifically address impairments commonly found in wireless and packet-based networks. The Voice Quality SVP compares the received audio with the sent audio, producing a Mean Opinion Score (MOS) that predicts overall subjective listening quality without requiring actual human testing. Real-time results reporting provide operators with full visibility into their network’s current performance, enabling them to respond rapidly to issues. Using this information, operators can enhance performance for greater profitability.

The Voice Quality SVP enables operators to test a variety of local and long distance scenarios, including mobile-to-mobile, mobile-to-wireline and wireline-to-mobile and compare the quality associated with specific access technologies (i.e., GSM vs. UMTS) or core networks (circuit-switched vs. packet-based.) Specific to mobile phones and networks, these test profiles are fully parameterized and extensible, which lets operators develop their own profiles to address complex or operator-specific test requirements. In addition to the fully automated test mode, the solution also provides operators with an interactive mode for validating network modifications prior to deployment or for troubleshooting network or service issues.

Key Features
