20、GSM 02.33 version 8.0.1 Release 1999 6 ETSI TS 101 507 V8.0.1 (2001-06) 1 Scope The present document provides the stage 1 description for a lawful interception function to be implemented in a given GSM PLMN in order for a network operator to be able to fulfil national lawful requirements. It shall b

21、e noted that national variation may exist but it is not the intention for the present document to encompass all of them. The purpose of the present document is to cover the options which may be selectable according to national regulations or as required by the GSM PLMN operator in co-operation with

22、their suppliers. In the preparation of the present document general reference was made to the European Union Council Resolution, January 1995: “International Requirements for the Lawful Interception of Telecommunications“. 2 Re fe re nces The following documents contain provisions which, through ref

23、erence in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version

24、applies.

Pl 31 3 3.1 Definitions and abbreviations Defi nit ions For the purposes of the present document, the following terms and definit

26、ions apply: Target: is the subject of an interception. Different identities might be used (i.e. Mobile Station International ISDN number (MSISDN), optionally International Mobile Subscriber Identity (IMSI) or International Mobile Equipment Identity (IMEI) Interception Area: is a subset of the Public

27、 Lands Mobile Network (PLMN) service area comprised of a set of cells which define a geographical zone Intercept product: data sent or received by the target, such as speech, fax or data generated by the users of the telecommunication services Intercept related information: collection of information

28、 associated to telecommunication services involving the target Law enforcement agency: body authorized by law to carry out telecommunication interceptions Location Dependent Interception: is interception within a PLMN service area that is restricted to one or several Interception Areas (IA) Warrant

29、reference number: is a reference number that links a specific intercept activity to an agencys lawful Interception request ETSI GSM 02.33 version 8.0.1 Release 1999 7 ETSI TS 101 507 V8.0.1 (2001-06) 3.2 Ab brevi at ions In addition to those below abbreviations used in the present document are liste

30、d in GSM O 1.04. IA Interception Area LEA Law Enforcement Agency 4 4.1 Description General principle GSM Public Lands Mobile Network (PLMN) shall provide access to the intercept product and the intercept related information of the mobile target on behalf of Law Enforcement Agencies (LEAS). A mobile

31、target in a given PLMN can be a subscriber of that PLMN, or a subscriber of another PLMN. The intercept product and the related information can only be delivered for activities on that given PLMN. An unambiguous correlation shall be established between the intercept related information and the inter

32、cept product. The intercept related information and the intercept product shall be delivered in as near real time as possible. Location Dependent Interception allows a PLMN to service multiple interception jurisdictions within its service area. Multiple law agencies with their own interception areas

33、 can be served by the PLMN. All the information or rules given for interception within a PLMN apply to interception within an IA when Location Dependent Interception is invoked. A target may be marked in one or more different IAS within the same PLMN. Interception is not required nor prohibited by t

34、his standard when Location Dependent Interception is active and the location of the target subscriber is not known or available. Additional GPRS interception requirements are contained in annex A. 4.2 Applicability to telecommunications services 4.2.1 Tele and bearer services (TS/BS) All teleservice

35、s and bearer services are subject to interception of the target. Interception is applicable to Short Message Service (SMS) point-to-point, but not SMS Cell Broadcast (SMSCB). Impact of application to the Voice Group Call Service (VGCS) and the Voice Broadcast Service (VBS) is for fkther study (FFS).

36、 4.2.2 Supplementary services (SS) 4.2.2.1 General It shall be possible to report any activities regarding supplementary services to the LEA. It may be a national or operatorhupplier option to implement this function. 4.2.2.2 Impact The application of the following supplementary services has no impa

37、ct on the interception function: Calling Line Identity PresentationKalling Line Identity Restriction (CLIPKLIR), Connected Line Identity PresentationKonnected Line Identity Restriction (COLPKOLR), Call Barring (CB) services, Advice of Charge (AOC) services, Closed User Group (CUG), Completion of Cal

38、ls to Busy Subscriber (CCBS). ETSI GSM 02.33 version 8.0.1 Release 1999 8 ETSI TS 101 507 V8.0.1 (2001-06) 4.2.2.3 Intercept of forwarding calls - option Activation by the target of any Call Forwarding (CF) service, Call Deflection (CD), or Explicit Call Transfer (ECT) shall result in the capability

39、 to intercept the forwarded, diverted or transferred product. It may be a national or operatorhpplier option which of these are implemented. 4.2.2.4 Intercept of calls placed on HOLD (call waiting and multi party services) - option In some countries it is a national requirement that when the target

40、puts other parties on HOLD (call waiting (CW) and multi party services (MPTY) the other parties product will be interrupted. When the other parties rejoin the call, the intercept product shall be reconnected. 4.2.2.5 Network operator specific services Impact on a network operators specific services

41、is not covered in the present document. 4.2.3 Other activities Location information in the format of cell global identity (CGI) should be available with call related activities. Conversion to other formats of location information (e.g. latitude/longitude) is not covered by the present document. It i

42、s a matter of national or operatorhupplier option whether location information shall be provided in connection with non call related activities, e.g. location update. 5 Normal Operation 5.1 Intercept administration A secure means of administrating the service by the PLMN operator and/or intercept re

43、questing entity is necessary. This mechanism shall provide means to activate, deactivate, show, or list targets in the GSM PLMN as quick as technically possible. The function shall be policed by appropriate authentication and audit procedures. The admmistration function shall allow specific IAS to b

44、e associated with target subscribers when Location Dependent Interception is being used. 5.1.1 Activation As a result of the activation it shall be possible to request for the specified target either the intercept product, the intercept related information or both, and the LEA destination addresses

45、for the delivery of the intercept product and intercept related information if required. These shall be selectable on a PLMN basis according to national options. 5.1.2 Deactivation As a result of deactivation it shall be possible to stop all interception activities for the specified target. 5.1.3 Se

46、curity The intercept function shall only be accessible by authorised personnel. No indication shall be given to any PLMN staff except authorised personnel that the intercept function has been activated on a target.

47、Password rules Password rules are specially defined for local and remote administrative and maintenance access. More specifically: - - - the minimum length of a password shall be eight characters; the password shall be valid for a limited number of days (e.g. 30 days); the system shall support passw

48、ord history, i.e. the last e.g. 20 passwords are not allowed. 5.1.3.2 Log files An audit log of the use of the intercept function (successful or failed) shall be maintained, accessible only to authorised users. It shall be configurable to maintain a log file for all Lawful Interception commands or i

49、ntercept relevant events on all network elements. The following events shall be logged with both time and date stamp and if available User-ID, Target- ID etc.: - - - - interception system failures; - maintenance work. activation, deactivation and interrogation of lawful interception; attempt of unauthorised access of lawful interception; communication failures at network element interfaces; The log file shall be password protected. The log file shall be maintainable separately from other non intercept operations (read, delete, download). The log file shall be cyclic deleted
