==Access point==
{{main|Access Point Name}}

An access point is:
* An IP network to which a mobile set can be connected
* A set of settings that are used for that connection
* A particular option in a set of settings in a mobile phone

When a GPRS mobile phone sets up a PDP context, the access point
is selected.  At this point an [[Access Point Name]] (APN) is
determined

:Example: aricenttechnologies.mnc012.mcc345.gprs
:Example: geocell
:Example: internet
:Example: hcl.cisco.ggsn

This access point is then used in a [[Domain Name System|DNS]] query to a private DNS
network.  This process (called APN resolution) finally gives the IP
address of the GGSN which should serve the access point.  At this
point a PDP context can be activated.
