ETSI ETSI TS 143 005 V13.0.0 (2016-01)63GPP TS 43.005 version 13.0.0 Release 131 Scope The present document contains technical performance objectives that should be met
25、for the fixed infrastructure of GSM PLMNs. Concerning transmission delay for the PLMN in clause 4, the requirements should also be met by GSM Mobile Stations (MS)s. These performance design objectives are applicable to all implementations at all points in the growth cycle up to the maximum size. The
26、se reference loads and performance objectives may be used by manufacturers in designing GSM PLMNs and by Administrations or Recognised Private Operating Agencies (RPOA)s in evaluating a specific design or for comparing different designs for potential use in the Administrations or RPOAs intended impl

Interfaces, interface characteristics, connections through an MSC and ancillary functions of the MSC are defined in 3GPP TS 11.30 16. The functions support
35、ed by HLRs and VLRs are given in 3GPP TS 11.31 17 and 11.32 18. Each MSC will be responsible for synchronisation, if required, with the fixed network to which it is connected. The requirements of ITU-T Recommendation Q.541 should be observed. Timing and synchronisation of the radio subsystem is spec
36、ified in the 3GPP TS 45.010 4. 3 Performance design objectives 3.1 General Part of the text is taken from ITU-T Recommendation Q.543 and part from CEPT Recommendation T/S 64-30. 3.2 MSCs 3.2.1 Reference loads The reference loads are traffic load conditions under which the performance design objectiv
37、es stated below are to be met. The following reference loads are defined. a) Reference load for incoming inter-exchange circuits; b) Reference load for circuit switched MS calls. Reference load A is intended to represent the normal upper mean level of activity which Administrations or RPOAs would wi
38、sh to provide for MSs, BS-MSC circuits and inter-exchange circuits. Reference load B is intended to represent an increased level beyond normal planned activity levels. 3.2.1.1 Reference load on incoming interexchange circuits a) Reference load A - 0,7 Erlang average occupancy on all incoming circuit
39、s with 35 call attempts/hour/incoming circuit. This figure assumes 45 % ineffective call attempts. b) Reference load B - 0,85 Erlang average occupancy on all incoming circuits with 42 call attempts/hour/incoming circuit. 3.2.1.2 Reference load for MS calls MS calls comprise MS originating and MS ter
40、minating traffic. Terminating call attempts from PSTN/ISDN to the MS are measured at the PSTN/ISDN interface of the PLMN. Terminating call attempts as part of the intra-PLMN MS-to-MS call attempts are measured at the GMSC functionality in the VMSC. ETSI ETSI TS 143 005 V13.0.0 (2016-01)83GPP TS 43.0

42、e chosen to cover field observations in various continents, countries and regions. With an increase of traffic per subscriber, the overall mean holding time tends to increase. The set Z is chosen as an extreme value, expressing the expectation that such a large value should only be observed in assoc
43、iation with a substantially increased overall mean holding time. b) Reference load B Reference load B is defined as a traffic increase over reference load A of: + 20% in Erlangs and. + 20% in BHCA. 3.2.1.3 Impact of supplementary services If the reference model MSC assumes that significant use is ma
44、de of supplementary services, the performance of the MSC can be strongly affected, especially in designs where processor capacity can become a limiting item. The performance delays recommended can be significantly lengthened at a given call load under such circumstances. The Administration or Operat
45、ing Agency defining the reference model should estimate the fractions of calls which use various supplementary services so that an average processor impact relative to a basic telephone call can be calculated. 3.2.2 Inadequately handled call attempts 3.2.2.1 Definition Inadequately handled call atte
46、mpts are attempts which are blocked (as defined in ITU-T E.600 series of Recommendations) or are excessively delayed within the exchange. “Excessive delays“ are those that are greater than three times the “0,95 probability of not exceeding“ values recommended in the tables. For originating and trans
47、it calls, this inadequately handled call attempt parameter applies only when there is at least one appropriate outlet available. 3.2.2.2 Probability of inadequately handled call attempts occurring The values in table 2 are recommended.

49、“ is understood as the expected value in the probabilistic sense. 2) The terms “received from“ and “passed to“ the signalling system are meant to be that instant at which the information is exchanged between the signalling data link (layer 1) and the signalling link functions (layer 2) in ITU-T Signalling System No. 7. For Dm channel signalling it is designated as that instant when the information is exchanged between the data link layer (layer 2) and the network layer (layer 3) by means of primitives. Conseq
