Checking access to closed subscriber group cells in a mobile network

A mobile station comprising:

• memory to store machine readable instructions;
• and a processor to execute the machine readable instructions to:
• store a second equivalent public land mobile network (EPLMN) list and a second RPLMN identifier before obtaining a first EPLMN list and a first registered public land mobile network (RPLMN) identifier via a subsequent packet switched domain registration procedure;
• perform a first access check based on the first EPLMN list and the first RPLMN identifier to determine whether the mobile station is allowed to access a closed subscriber group (CSG) cell;
• perform a second access check based on a second EPLMN list and a second RPLMN identifier to determine whether the mobile station is allowed to access the CSG cell, wherein the second EPLMN list and the second RPLMN identifier respectively comprise an EPLMN list and an RPLMN identifier obtained via a most recent circuit switched domain registration procedure, and the second access check comprises comparing a PLMN identifier associated with the CSG cell with the second EPLMN list and the second RPLMN identifier;
• and
• condition reporting of the CSG cell based on the first access check and the second access check.
