22、uly 1997 Foreword This ETSI Technical Report (ETR) has been produced by the Terrestrial Trunked Radio (TETRA) Project of the European Telecommunications Standards Institute (ETSI). ETRs are informative documents resulting from ETSI studies which are not appropriate for European Telecommunication Sta
23、ndard (ETS) or Interim European Telecommunication Standard (I-ETS) status. An ETR may be used to publish material which is either of an informative nature, relating to the use or the application of ETSs or I-ETSs, or which is immature and not yet suitable for formal adoption as an ETS or an I-ETS. P
24、revious page is blank - STDmETSI ETR 272-ENGL 1797 3400855 0217158 b33 = Page 9 ETR 292: July 1997 1 Scope This ETSI Technical Report (ETR) provides an overview of the network management requirements in a Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D) mobile radio system. The primary motiva
25、tion of this ETR is to provide a starting point to facilitate central network management of TETRA systems from different manufacturers. After an overview of network management in TETRA, this ETR outlines the approach to the work, followed by the specification of the management services and informati
26、on flows. Finally a standardization strategy for network management for TETRA is given. The guiding principle in the examination of central Telecommunications Management Network (TMN) management services has been that the Central Network Management (CNM) facility will generally fulfil a monitoring r
27、ole rather than a controlling role, although performing some limited controlling functions such as temporarily disabling and enabling individual subscribers. With this constraint, an examination of the necessary central network management functions indicates that only a subset need to be standardize
28、d in order to support a high degree of inter-operability between different manufacturers TMN management services. It appears that the following network management functionalities require access from the CNM facility (or, in the case of items d) and (g), require standardization in support of that acc
29、ess): a) management of subscribers (for temporary actions only); b) subscriber activity log and subscriber diagnostics: c) access to system performance measurement data: d) access to network management facilities; e) fault and maintenance data; f) testing and recovery of network support links, in pa
30、rticular the Local to Central Network Management link (LNM-CNM link); g) accounting management. It is clear that remote access to the LNM facilities from the centre will need to be supported by appropriate authentication and authorization procedures optionally including encryption over the LNM-CNM l
31、ink. In this ETR all of the local and central telecommunications management functions are examined and those that require to be standardized to allow remote CNM operation, as defined above, are identified. The local/central/local network management information flows required to support the CNM funct
32、ions are studied and recommendations are made for defining TMN standard protocols and procedures. 2 References This ETR incorporates by dated and undated reference, provisions from other publications.

35、I ti ons For the purposes of this ETR, the following definitions apply: Base Station (6s): A physical grouping of equipment which provides the fixed portion of the air interface. One base station transmits and receives radio signals to and from a single location area (a single region of geographical
36、 coverage). A BS contains at least one Base Radio Stack (BRS). cell: The smallest geographical area where TETRA services may be obtained, using a certain set of radio frequencies. Cipher Key (CK): A value that is used to determine the transformation of plain text to cipher text in a cryptographic al
37、gorithm. cipher text: The data produced through the use of encipherment. The semantic content of the resulting data is not available (IS0 7498-2). decipherment: The reversal of a corresponding reversible encipherment (IS0 7498-2). enciphermenencryption: The cryptographic transformation of data to pr
38、oduce cipher text. (IS0 7498-2). entity: A point at which a packet is manipulated (ag. sourced, sunk, routed or switched). gateway: A device which will enable the interconnecting of two networks which inherently use different and incompatible protocols. historical data: Record of a past event or ser
39、ies of events. Historical data from triggered events may start at some point in the past up to the present. home location register: A database in the Mobile Station (MS) home system which keeps track of the position of the MS. The home location register is used to indicate where the MS should be pag
40、ed. key: A sequence of symbols that controls the operations of encipherment and decipherment. key management: The generation, selection, storage, distribution, deletion, archiving and application of keys in accordance with a security policy. network: A collection of subscriber terminals interconnect
41、ed through telecommunications devices. plain text: The unencrypted source data. The semantic content is available. real tirne: Refers to the generation of network management information in a timeframe comparative to the real life process that it is controlling or monitoring. signalling: The exchange
42、 of Information specifically concerned with the establishment and control of connections, and with management, in a telecommunication network. site: Physical location within the network. subscriber activity log: A system record which contains information on attacwdetach ITSI; enable/dicable terminal
43、; registrations; location updates vs. time; call re-establishment; authentications; call start time, call end time, and called party; type of call; Supplementary Services invoked; whether uplink BER or MER are below an operator pre-determined threshold; plus any other relevant activity record. subsc
44、riber data: A system record which contains information on the individual subscriber ITSI, GTSls, Supplementary Services allowed, privileges allowed and other system accesses allowed. subscriber management: The system functionality for dealing with subscribers to the system. Page 11 ETR 292: July 199
45、7 subscriber terminal: An equipment which an internal user can use to communicate with another user. Mobile Stations (MS) and Cine Stations (LS) are the only types of subscriber terminal. Supplementary Service: A Supplementary Service modifies or supplements a bearer service or a teleservice. A Supp
46、lementary Service cannot be offered to a customer as a stand alone service. It should be offered in combination with a bearer service or a teleservice. Switching and Management Infrastructure (SwMI): All of the TETRA equipment for a Voice plus Data (V+D) network except for subscriber terminals. The
47、SwMI enables subscriber terminals to communicate with each other via the SwMI. transaction (packet transaction): All the processes and procedures associated with the transmission of one packet of information between peer network layer protocol entities on opposite sides of the air interface. transac
48、tion (voice transaction): Part of a voice call comprising the transmissions of each talking party. The total of all transactions make up the call. transferred account procedure: Name given to the central accounting procedure defined in the GSM standards. The transferred account procedure is used to
49、allocate costs to roamed mobiles. 3.2 Abbrevi atlons For the purposes of this ETR, the following abbreviations apply: ACL ACSE ASN BER 6 IC BOC i3 RS BS CK CMIP CMIS CMOT CNM cs CUG DES DGNA E FD GDMO GOS GSM GTSI HLR 15 ISDN IS1 ITS1 ITU LA LNM LS MER M FA MI6 MS NMC NMS os I Access Control List Associated Control Service Element Abstract Syntax Notation Bit Error Rate Barring Incoming Calls Barring Outgoing Calls Base Radio Stack Base Station Cipher Key Common Management Information Protocol Common Management Information Service CMIP Over TCPAP Central Network Manag
