Abstract
A cellular communication system uses a policy control rule function (PCRF) to allow or deny a particular user or user group access to a given access point name (APN). An allowed APN may support static IP address assignment for that user/user group. By restricting requested APNs via a test in the PCRF, frequent changes to the user's home service server (HSS)/home location registry (HLR) supporting static IP address can be avoided while ensuring that designated users will have access to an APN that supports the needed IP address pool.
