QoS Requested
Quality of service enables you to specify connection conditions. For a GPRS connection, a
quality of service profile consists of 5 parameters:
Precedence
When operating conditions are lower than normal, the network tries to maintain service for all
profiles. Priority specifies the importance of one profile compared to the others. This means that
if the network is overloaded, the profile with the highest priority will be maintained before the
others.
Delay
Specifies the maximum time allowed for data transmissions over the GPRS network. Values may
range from 1 (shortest time) to 4 (any time).
Reliability
Reliability specifies the properties (in terms of transmission errors) required for the application to
operate properly. The values range from 1 to 5:
• Choice 1 ("Deferred" traffic: applications sensitive to transmission errors and not
capable of handling lost data).
• Choice 2 ("Deferred" traffic: applications sensitive to transmission errors and capable of
handling occasional lost data).
• Choice 3 ("Deferred" traffic: applications sensitive to transmission errors and capable of
handling lost data).
• Choice 4 ("Real time" traffic: applications sensitive to transmission errors and capable
of handling those errors).
• Choice 5 ("Real time" traffic: applications not sensitive to transmission errors and
capable of handling those errors).
Peak throughput
Specifies the maximum data transmission rate for the network. There is no guarantee that this
limit will be reached.
Mean throughput
Specifies the average data transmission rate for the network.
