Structure of An APN
A structured APN consists of two parts as shown in the accompanying figure.
- Network Identifier: Defines the external network to which the Gateway GPRS Support Node (GGSN) is connected. Optionally, it may also include the service requested by the user. This part of the APN is mandatory
- Operator Identifier: Defines the specific operator’s packet domain network in which the GGSN is located. This part of the APN is optional. The MCC is the Mobile Country Code and the MNC is the Mobile Network Code which together uniquely identify a mobile network operator.
Examples of APN are:
- Example: internet.t-mobile
- Example: internet.mnc012.mcc345.gprs
- Example: internet (NOTE: This APN example does not contain an operator)
- Example: prepaid internet (NOTE: This APN example does not contain an operator and contains a space)

Famous quotes containing the words structure of and/or structure:
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
