3.1 Definitions
initiating subscriber: mobile subscriber who modifies the Follow Me data of the remote party.
initiating number: number (the MSISDN of the initiating subscriber) to which incoming calls, originally destined for the remote party, shall be forwarded. It is subsequently also referred to as MSISDNA.
remote party: is characterised by the remote number which is defined in the numbering plan of a PLMN operator. The Follow Me feature enables the initiating subscriber to modify the Follow Me data of the remote party. In particular cases the remote party is a GSM subscriber of the PLMN and the remote number denotes her basic MSISDN.
Previously registered subscriber: Is the initiating service subscriber who has registered Follow Me with respect to a remote party. Her Registration can be erased by herself or by an FM service supervisor via forced erasure procedure.
FM service supervisor: is an initiating subscriber who is allowed to modify the Follow Me data of a remote party who has been registered to a previously registered subscriber for the Follow Me application. The FM service supervisor shall be authorised by her network operator.
remote number: is a number in E.164 format which identifies a remote party. In general this number is not assigned to a subscriber and can be regarded as a "dummy MSISDN". In particular cases the remote party is a GSM subscriber of the PLMN and the remote number denotes her basic MSISDN. The remote number is entered by the initiating subscriber for registration, interrogation, forced erasure and erasure of the Follow Me feature with respect to the remote party.
Follow Me function node: is a network node in the PLMN operator of the remote party. The FM data of the remote party are stored in this node. This node can be implemented in:
– an HLR;
– any other operator specific network node e.g.:
– a gsmSCF;
– an SCP.
