Wild Card APN

The APN (Access Point Name) field in the HLR (Home Location Register) may contain a wild card APN if the HPLMN (Home Public Land Mobile Network) operator allows the subscriber to access any network of a given PDP (Packet Data Protocol) Type. If an SGSN (serving GPRS Support Node) has received such a wild card APN, it may either choose the APN Network Identifier received from the Mobile Station or a default APN Network Identifier for addressing the GGSN (Gateway GPRS Support Node) when activating a PDP context.
