ETSI ETSI TS 122 094 V14.0.0 (2017-03)53GPP TS 22.094 version 14.0.0 Release 141 Scope The present document specifies the stage 1 description for the Follow Me feature. The Follow Me feature enables a mobile subscriber A to manipulate the Follow Me
22、data of a party B in such a way that - under certain conditions - subsequent calls directed to party B will be forwarded to subscriber A. The feature is described from the service subscribers and users point of view, in particular: - the procedure for normal operation with successful outcome; - the
23、action to be taken in exceptional circumstances; - the interaction with other GSM services and features. This TS does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the appropriate specifications. Any interaction with other services and/or networks not dealt with
24、in this specification are outside the scope of this TS. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc

29、P TS 22.094 version 14.0.0 Release 143 Definitions, symbols and abbreviations 3.1 Definitions initiating subscriber: the mobile subscriber which modifies the Follow Me data of the remote party. remote party: Is characterised by a number in E.164 format defined in the numbering plan of a PLMN operato
30、r. The Follow Me feature enables the initiating subscriber to modify the Follow Me data associated with this number. In general this number is not assigned to a subscriber. In particular cases the remote party is a subscriber of the PLMN and the number denotes her basic MSISDN. FM service supervisor
31、: Is an initiating subscriber who is allowed to modify the Follow Me data of a remote party who has been registered to another initiating subscriber for the Follow Me application. The FM service supervisor shall be authorised by her network operator. 3.2 Abbreviations For the purposes of this TS the
32、 following abbreviations apply, in addition, abbreviations used in this TS are listed in 3GPP TS 21.905 1. FM Follow Me feature 4 Description Follow Me enables an initiating mobile subscriber A to have control over the Follow Me data of a remote party B. Initiating Subscriber A shall be able to mani
33、pulate the Follow Me data of remote party B such that subsequent calls directed to remote party B are forwarded to initiating subscriber A. Initiating subscriber A needs to have FM provisioned by her service provider. In case remote party B is a subscriber she needs to have FM provisioned by her ser
34、vice provider too. The FM service supervisor shall be able to modify the Follow Me data of the remote party who has been registered to another initiating subscriber. It remains in the responsibility of a FM provisioning service provider to confine a.) the range of remote parties for which a FM provi
35、sioned subscriber may become initiating subscriber b.) the range of potential initiating subscribers for a remote party. The mobile subscriber who has been provisioned Follow Me is able to use the following control operations: Registration available to the initiating subscriber Interrogation availab
36、le to the initiating and remote party in case the remote party corresponds to a subscriber Erasure available to the initiating and remote party in case the remote party corresponds to a subscriber (There is no explicit activation or deactivation.) The FM service supervisor is able to use the followi
37、ng control operations: Interrogation Erasure (forced erasure) NOTE 1: The functionality of the Follow Me feature is equivalent to the Call Forwarding Unconditional Supplementary Service (see 3GPP TS 22.082 5), controlled by initiating subscriber A and effecting remote party B. ETSI ETSI TS 122 094 V
38、14.0.0 (2017-03)73GPP TS 22.094 version 14.0.0 Release 14NOTE 2: The Follow Me feature is designed in such a way that the requirements of “functional addressing“, which is needed for GSM-Railway operators, can be met. The concept of “functional addressing“ enables a subscriber to set up a call to a
39、“function“ - e.g. the conductor - on a “train“. The Follow Me feature identifies this “function“ with the remote party B. Consequently a “functional number“ is the equivalent to the number of remote party B (e.g. the MSISDN of a subscriber B). A call to that “functional number“ (the conductor on a p
40、articular train - to stay with the example) will be forwarded to the MS of the person, who is on duty as a conductor at this time for this train. In the context of the Follow Me feature, this person (the train conductor) constitutes the “initiating subscriber“ A, who has registered Follow Me with re
41、spect to the remote party B (the “function“ train conductor). 4.1 Normal Operation Due to reduced security requirements to the Follow Me feature the service shall not be offered in standard operations of public 3GPP networks. In railway operations it must be enabled by definitive action on the part
42、of the operator. Fraud Information Gathering System (FIGS) as specified in 11 can be used to protect in CAMEL based inter-working networks. The Follow Me feature shall be controlled by means of Subscriber Controlled Input using USSD. 5 Applicability to telecommunication services 3GPP TS 22.001 descr
43、ibes the principles of the Telecommunication services provided in a PLMN. It also defines the concepts of Telecommunication services and describes their characterization by appropriate attributes. Bearer services and Teleservices, which are offered by a PLMN in connection with other networks, are de
44、fined in 3GPP TS 22.002, 3GPP TS 22.003 and 3GPP TS 22.101. A list of basic service groups can be found in 3GPP TS 22.004. Follow Me is applicable to the following telecommunication services: Table 1: Applicability of the Follow Me feature to telecommunication services Feature Telephony Emergency Ca

However a dispatcher may be an initiating subscriber or a remote party for the Follow Me f
46、eature. EDITORs Note: The applicability of FM to SMS is for further study. 6 Normal procedures with successful outcome 6.1 Provision Follow Me shall be provided after prior arrangement with the service provider. Follow Me will be provisioned for all Basic Services subscribed to and to which it is ap
47、plicable. NOTES: - A Follow Me provision is required for the initiating subscriber and for the remote party in case the remote party corresponds to a subscriber. - If Follow Me is provisioned for a mobile subscriber she may assume the role of an initiating subscriber and/or the role of a remote part
48、y. ETSI ETSI TS 122 094 V14.0.0 (2017-03)83GPP TS 22.094 version 14.0.0 Release 14- A Follow Me provisioning service provider may confine: a.) the range of remote parties for which a FM provisioned subscriber may become initiating subscriber b.) the range of potential initiating subscribers for a re
49、mote party. c) the range of remote parties for which a FM provisioned subscriber may become FM service supervisor. NOTE: (Health warning on security) The Follow Me feature is designed in such a way as to meet the security requirements of GSM-Railway operators. If the Follow Me feature is to be used by other operators - in particular if the remote party corresponds to a subscriber - operators are strongly advised to care for additional suitable security mechanisms to protect the remote party from potential harm by misuse of FM.
