Access Point Name
Access Point Name or APN is the name of an access point for GPRS.
An access point is:
- An IP network to which a mobile can be connected
- A set of settings which are used for that connection
- A particular option in a set of settings in a mobile phone
This access point is then used in a 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.
The APN DNS record is in the form of apn.mnc(Network Code).mcc(Country Code).gprs. The numbering is defined by ITU-T E.212.
