114.2.3 General Data Service KPIs
The following KPIs are computed for all or many of the data services supported (as indicated in the above diagrams):
114.2.3.1. Service Non-Accessibility (%)
Denotes the probability that a subscriber cannot access the service successfully due to a failure that has occurred either during PDP context activation or during service access. This means that the data transfer cannot be started.

Note:This KPI is defined differently for streaming. See section "Streaming KPIs". |
114.2.3.2. Setup Time (s)
Denotes the period of time it takes to access a service successfully, from the moment the dial-up connection is established until the first data packet is received.
114.2.3.3. IP Service Access Failure Ratio (%)
Denotes the probability that, after successfully activating a PDP context, a subscriber cannot access the service, so that the data transfer cannot be started.
114.2.3.4. IP Service Setup Time (s)
Denotes the time period needed to establish a TCP/IP connection to the FTP server, from sending the initial query to a server until the first data packet is received.
114.2.3.5. Mean Data Rate (kbit/s)
Denotes the average data rate measured throughout the entire connect time (application throughput).
114.2.3.6. Data Transfer Cut-off Ratio (%)
Denotes the probability that a data transfer cannot be completed when it has been started successfully.
114.2.3.7. Data Transfer Time (s)
Denotes the time needed to successfully complete a data transfer.
