31、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 initiati
32、ng 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 r
33、emote party. Her Registration can be erased by herself or by an FM service supervisor via forced erasure procedure. ETSI ETSI TS 123 094 V15.0.1 (2018-07)63GPP TS 23.094 version 15.0.1 Release 15FM service supervisor: is an initiating subscriber who is allowed to modify the Follow Me data of a remot
34、e 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 subscrib
35、er 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 feat
36、ure 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. 3.2 Ab
37、breviations FFN Follow Me function node FM Follow MeSCP Service Control Part Other abbreviations used in this ETS are listed in 3GPP TR 21.905. 4 Handling of Follow Me 4.1 General Follow Me enables an initiating mobile subscriber A to have control over the Follow Me data of a remote party B. The rem
38、ote party B is characterised by the remote number which is defined in the numbering plan of a PLMN operator. Initiating Subscriber A shall be able to manipulate the Follow Me data of remote party B such that subsequent calls destined for remote party B are forwarded to initiating subscriber A. In th
39、e case of Forced Erasure by an FM service supervisor, the initiating subscriber is allowed to erase the Follow Me data of a remote party who has been registered to a different initiating subscriber for the Follow Me application. Follow Me is a PLMN specific feature and the control operations of FM a
40、re based on USSD. All messages between the MS and the mobile network and internal to the mobile network are USSD messages. The present document deals with the control operations of FM in HLRa and FFN. If the FFN is an HLR, the control of the requests for both FM and CFU services is specified (see su
41、bclause 4.3.2). The functionality of forwarding calls for remote party B to initiating subscriber A (after successful registration of FM) is out of the scope of the present document. This functionality is the same as the functionality of the Call Forwarding Unconditional Supplementary Service applie
42、d to all telecommunication services of remote party B for which CFU is applicable. NOTE 1: the “served mobile subscriber“ in 3GPP TS 22.094 5 corresponds to the “remote party“ in the present document and the “forwarded-to subscriber“ in 3GPP TS 22.094 5 corresponds to the “initiating subscriber“ in
43、the present document. NOTE 2: The forwarding of calls for remote party B to initiating subscriber A can be achieved by invoking the Call Forwarding Unconditional Supplementary Service or by making use of an equivalent operator specific service (e.g. via CAMEL). The functionality of the control of Fo
44、llow Me (registration, erasure, forced erasure and interrogation) is split between the HLR of the initiating subscriber A (HLRa) and the FFN of the remote party B (FFNb). ETSI ETSI TS 123 094 V15.0.1 (2018-07)73GPP TS 23.094 version 15.0.1 Release 154.1.1 Provision FM can be registered / erased / in
45、terrogated by an initiating subscriber A with respect to a remote party B if both parties are provisioned with FM. To enable forced erasure by an FM service supervisor, the FM service shall be provisioned to the FM service supervisor. Additionally, she needs the subscription entitlement to perform t
46、he forced erasure. NOTE: In general remote party B does not correspond to a GSM subscriber. In this case provisioning of FM for remote party B is operator specific. If remote party B is a GSM subscriber and if the forwarding of calls for remote party B to initiating subscriber A is achieved by invok
47、ing the Call Forwarding Unconditional Supplementary Service, provision of CFU for remote party B is required. 4.1.2 Registration The initiating subscriber registers the FM feature with respect to a particular remote party. If an initiating subscriber A successfully registers FM with respect to a rem
48、ote party B then FM becomes registered, active and operative for remote party B. As a result of the registration subsequent calls directed to remote party B are forwarded to initiating subscriber A. NOTE: The remote party cannot register FM with respect to herself. 4.1.3 Erasure If an initiating sub
49、scriber A or the FM service supervisor successfully erases FM with respect to a remote party B then FM becomes not registered and not active for remote party B. For forced erasure by the FM service supervisor the previously registered subscriber shall be informed of the successful forced erasure via a network initiated USSD Notify message with appropriate contents. This message is sent by the FFN. If remote party B is a GSM subscriber and successfully erases FM then FM becomes not registered and not active for remote party B. 4.1.4 Interrogation If
