21、.0 (2018-07)53GPP TS 22.042 version 15.0.0 Release 151 Scope The present document describes the feature Network Identity and Timezone (NITZ). This feature provides the means for serving PLMNs to transfer current identity, time, Daylight Saving Time and the local timezone to Mobile Stations (MS)s, an
22、d for the MSs to store and use this information. This enhances roaming by permitting accurate indication of PLMN identities that are either newer than the Mobile Equipment (ME) or have changed their name since the ME was sold. Additionally time, Daylight Saving Time and timezone information can be u
23、tilised by MEs as desired. 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.) or non-specific. For a spe
24、cific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present
25、 document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TS 24.008: “Mobile radio interface layer 3 specification; Core Network Protocols - Stage 3“. 3 3GPP TS 23.038: “Alphabets and Languages“. 3 Definitions and abbreviations In addition to the following definitions, abbreviations
26、used in the present document are listed in 3GPP TR 21.905 1. NITZ The feature Network Identity and Timezone as described in the present document. UCS2 Universal Character Set 2 UT Universal Time LTZ Local Time Zone, the offset from UT applying in that locality, including any adjustments for summer t
27、ime, etc. DST Daylight Saving Time. Adjustment for summer time. 4 Description The feature Network Identities and Timezone shall make it possible for a serving PLMN to transfer its current identity, universal time, DST and LTZ to MSs, and for the MS to store and use this information. Each one of thes
28、e elements is optional. The feature significantly enhances roaming as itenables the accurate indication of network identities that are either newer than the ME or have changed their name since the ME was manufactured or sold. Additionally time and timezone information can be utilised by MEs as desir
29、ed. When using the default character set (see 3GPP TS 23.038 3), the serving PLMN shall make both a “short“ and a “long“ name available to the MS. As an alternative or, in addition, to the default character set, the serving PLMN can make a name available in UCS2. The MS shall be free to choose one o
30、f these names depending upon its own characteristics and/or limitations, such as those of its display. NOTE: Guidance is sought, particularly from non-European operators, as to whether long and short name is required in UCS2 format. ETSI ETSI TS 122 042 V15.0.0 (2018-07)63GPP TS 22.042 version 15.0.
31、0 Release 15The Network Operator may change the network identity at any time. However the change of network identity need not force immediate transfer of information to the MS. As a network option, it shall be possible to send universal time (UT) by the network. Time information shall include: Year,
32、 Month, Day, Hour, Minute, Second, Timezone and DST. The expected accuracy of the time information is in the order of minutes. NOTE: Universal time indicates the time at which this information element (see 3GPP TS 24.008 2) may have been sent by the network. Thus it can be assumed that the accuracy
33、of the time information when it arrives at the MS is usually within a couple minutes. The serving PLMN shall make Local Time Zone (LTZ) available to the MS as an offset from Universal Time in units of 15 minutes. When the LTZ is compensated for DST (summertime), the serving PLMN shall provide a DST
34、parameter to indicate this. The adjustment for DST can be +1h or +2h. For PLMNs which cover more than one timezone, it is assumed that the Network Operator will arrange for boundaries between subsets of the PLMN service area to be approximately aligned with timezone boundaries. When an MS changes Lo
35、cal Time Zone the PLMN is not required to immediately transfer new time zone information. Similarly the PLMN will transfer the LTZ changes arising from summer/winter adjustments when convenient to the network operator. The MS will implement the new time zone information at an appropriate time follow
36、ing receipt. The information passed to MSs supporting the NITZ feature is controlled by the serving PLMN Operator through administrative interaction. The interface necessary to support this administrative interaction is outside the scope of the present document. 5 Applicability Network Identity and
37、Timezone is both an optional network feature and an optional MS feature. The NITZ feature is not intended to replace the existing method of PLMN Indication, nor is it intended to discharge the administration and maintenance of the associated MoU Permanent Document, SE13. 6 Normal procedure 6.1 Trans
38、fer of NITZ information Network name, time, DST and timezone information can be transferred from the serving PLMN to the MS: 1) Upon registering on the network. 2) When the MS geographically relocates to a different Local Time Zone. 3) When the network changes its Local Time Zone, e.g. between summe
39、r and winter time. 4) When the network changes its identity. 5) At any time during a signalling connection with mobile station. Transfer of relevant information shall not unduly consume scarce network resources. 6.2 Use of NITZ information Relevant information shall be presented to the MS user at th
40、e earliest opportunity. It is expected that the MS will display the most up to date information transferred to it. Switching off the MS should not cause the updated name of the network(s) to be deleted. Removal of the SIM/USIM should not cause the updated name of the network(s) to be deleted. ETSI E

Usage of time information in MS is a ME manufacturer issue. For example, time information can be utilised to time stamp transaction
