Questions tagged [access-point]

Access Point is a configurable network identifier used by a mobile device when connecting to a GSM carrier.

Access Point identifies an IP Packet Data Network (PDN), that a mobile data user wants to communicate with. In addition to identifying a PDN, an access-point may also be used to define the type of service, (e.g. connection to wireless application protocol (WAP) server, multimedia messaging service (MMS)), that is provided by the PDN. APN is used in 3GPP data access networks, e.g. general packet radio service (GPRS), evolved packet core (EPC).

enter image description here

A structured Access-Point 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.
