  11. 11. APN <ul><li>Access Point Name (APN) is a part of GPRS subscription data which is stored in Home Location Register (HLR) and which is transferred to the SGSN upon the activation of a GMM-Context. </li></ul><ul><li>APN has to be defined in GGSN too. </li></ul><ul><li>APN is split into two parts : </li></ul><ul><ul><li>Network Identifier : </li></ul></ul><ul><ul><ul><li>Mandatory </li></ul></ul></ul><ul><ul><ul><li>Example : www.xlgprs.net </li></ul></ul></ul><ul><ul><li>Operator Identifier : </li></ul></ul><ul><ul><ul><li>Optional, except for inter-PLMN roaming </li></ul></ul></ul><ul><ul><ul><li>Example : mnc011.mcc510.gprs </li></ul></ul></ul><ul><ul><li>Max APN Length : 100 octets. </li></ul></ul><ul><ul><li>Max Network Identifier Length : 63 octets </li></ul></ul><ul><ul><li>Max Operator Identifier : 100 – Network Identifier Length </li></ul></ul><ul><li>There are wildcard APN (*) on HLR.
