Working with Access Point Names (APNs)
APN is the access point name that is configured in the GGSN configurations. The GGSN’s APN support
offers the following benefits:
• Extensive parameter configuration flexibility for the APN.
• Extensive QoS support.
• Virtual APNs to allow differentiated services within a single APN. The APN that is supplied by the
mobile station is evaluated by the GGSN in conjunction with multiple configurable parameters.
Then the GGSN selects an APN configuration based on the supplied APN and those configurable
parameters.
• Traffic policing that governs the subscriber traffic flow if it violates or exceeds configured peak or
committed data rates. The traffic policing attributes represent a QoS data rate limit configuration for
both uplink and downlink directions.
Up to 1024 APNs can be configured in the GGSN. An APN may be configured for any type of PDP
context, i.e., PPP, IPv4, IPv6 or both IPv4 and IPv6.
Many parameters can be configured independently for each APN on the device. They are categorized as
given below:
• Accounting—Various parameters regarding accounting possibilities, such as, charging
characteristics, accounting mode (RADIUS server-based accounting, GTPP-based accounting, and
so on.)
• Authentication—Various parameters regarding authentication, such as, protocols used, like,
Challenge Handshake Authentication Protocol (CHAP), Password Authentication Protocol (PAP),
or none, default username/password, server group to use, and limit for number of PDP contexts.
• Enhanced Charging—Name of rulebase to use, which holds the enhanced charging configuration
(for example, eG-CDR variations, charging rules, prepaid/postpaid options, etc.).
