Method for monitoring and identifying radio coverage gaps of a public land mobile network (PLMN) comprising usage of stand alone signaling transfer points (SASTP) producing list of cells, the method comprising the capturing of an update location (UL) message in the case of logging in a mobile communication device into the network and a cancel location (CL) message in the case of leaving the network, whereas the update location (UL) message and the cancel location (CL) message comprise an information identifying the mobile communication device, particularly the international mobile subscriber indentity number (IMSI), comprising generation of provide subscriber info message, whereas the provide subscriber info response (PSI_Resp) message from last visited VLR comprise a cell identification (CeIl_ID) identifying the cell of the public land mobile network (PLMN) which was last used and/or in which the mobile communication device has left the network and further comprising the generation of a report message including the cell identification (CeII_ID).

Method according to one of the preceding claims, characterised in that the identifying information about the mobile communication device, particularly the international mobile subscriber indentity number (IMSI), is extracted and stored, particularly temporary stored.
Method according to one of the preceding claims, characterised in that the update location (UL) message is captured by and/or received from a visitor location register (VLR).
Method according to one of the preceding claims, characterised in that the update location (UL) message is forwarded to a home location register (HLR).
Method according to one of the preceding claims, characterised in that the cancel location (CL) message is captured by and/or received from a home location register (HLR).
Method according to one of the preceding claims, characterised in that a message including a mobile subscriber ISDN number (MSISDN) is generated by and/or received from a home location register (HLR), particularly after forwarding the update location (UL) message to the home location register (HLR).
Method according to one of the preceding claims, characterised in that the identifying information about the mobile communication device, particularly the international mobile subscriber indentity number (IMSI), and a mobile subscriber ISDN number (MSISDN) of the mobile communication device is stored in a database, particularly temporary stored.
Method according to one of the preceding claims, characterised in that the cancel location (CL) message is forwarded to a visitor location register (VLR).
Method according to one of the preceding claims, characterised in that the visitor location register (VLR) generates a provide subscriber info response message including the cell identification (Cell_ID).
