3… no longer have the right to update the specification ! CHANGE REQUESTOnce a 3GPP specification has come under change control, the Working Group and/or the specification official rapporteur …… no longer have the right to update the specification !
4CHANGE REQUESTBut it is still possible to develop the standard further, to add the missing parts, and to correct errors and/or omissions as the overall system becomes better defined.If the responsible Working Group wishes to make a change to the specification …… the working group must raise a Change Request.
5CHANGE REQUEST The CR consists of a cover page … … and an extract from the specification under consideration showing, using revision marks, all additions and deletions.Several iterations of a CR may be required until the WG is happy with it ...And the WG finally “agrees” upon the CR.
7CHANGE REQUEST There are 22 “comments” on the front page ! For HELP on using this form look at the pop-up text over the [H1] symbols. Comprehensive instructions on how to use this form can be found at [H1] For help on how to fill out a field, place the mouse pointer over the special symbol closest to the field in question.Here are some examples :Document numbers are allocated by the Working Group Secretary.Use the format of document number specified by the 3GPP Working Procedures, e.g. SSpec Number : enter the specification number in this box, e.gDo not prefix the number with anything . i.e. do not use "TS", "GSM" or "3GPP" etc.
8CHANGE REQUEST CR Num : enter the CR number here. This number is allocated by the 3GPP Support Team (MCC); it consists of four digits, padded with leading zeros if necessary, e.grev : enter the revision number of the CR here, e.g. 1.If it is the first version of the CR, use a "-".Current version x.y.z : enter the version of the specification here. This number is the version of the specification to which the CR was written and (normally) to which it will be applied if it is approved, e.gMake sure that the latest version of the specification (of the relevant release) is used when creating the CR.If unsure what the latest version is, go to and look it up !
9CHANGE REQUEST UICC apps : SIM / USIM / ISIM applications [H1] Proposed change affects : Mark one or more of the boxes with an X) :UICC apps : SIM / USIM / ISIM applications [H1]ME [H2]Radio Access NetworkCore Network [H1]SIM / USIM / ISIM applications [H2]Title : enter a concise description of the subject matter of the CR. It should be no longer than one line, but if this is not possible, do not enter hard new-line characters. Do not use redundant information such as "Change Request number xxx to 3GPP TS xx.xxx (Release x)".Source to WG : One or more organizations (ALL must be 3GPP Individual Members) which drafted the CR and are presenting it to the Working Group, e.g. NOKIA Corporation, Telefon AB LM Ericsson, Research in Motion UK Limited.
10CHANGE REQUESTSource to TSG : for CRs agreed at Working Group level, the identity of the WG. Use the format "xn" where x = "C" for TSG CT, "R" for TSG RAN, "S" for TSG SA, "G" for TSG GERAN; n = digit identifying the Working Group; for CRs drafted during the TSG meeting itself, use "P (Plenary)". Examples : "C4", "R5", "S4“, “GP".Work item code : enter the acronym for the work item which is applicable to the change request.This field is mandatory (for Release 4 and later). A list of work item acronyms can be found in the 3GPP work plan. See and, specifically for the WI code list,Examples : “GPRS“, “MIMO“, “TEI8“.
11CHANGE REQUESTDate : Enter the date on which the CR was last revised. Format to be interpretable by English version of MS Windows ® applications, e.g. 19/08/2009.Category : Enter a single letter corresponding to the most appropriate category listed , e.g. “F”. For more detailed help on interpreting these categories, see Technical Report "TSG working methods".Use one of the following categories: F (correction) A (corresponds to a correction in an earlier release – ie a “mirror” CR) B (addition of new functionality) C (modification of existing functionality) D (pure editorial, having no technical impact)Release : Use one of the following releases: R99 (Release 1999) Rel-4 (Release 4) Rel-5 (Release 5) Rel-6 (Release 6) Rel-7 (Release 7) Rel-8 (Release 8) Rel-9 (Release 9) Rel-10 (Release 10)All earlier Releases are closed; no maintenance is carried out on those Releases’ specs.
12CHANGE REQUESTReason for change : enter text which explains why the change is necessary.Summary of change : enter text which describes the most important components of the change, i.e. How the change is made.Consequences if not approved : enter here the consequences if this CR were to be rejected. It is mandatory to complete this section only if the CR is of category "F" (i.e. correction), though it is useful for other categories.Clauses affected : enter the number of each clause which contains changes. Be as specific as possible (i. e. list each sub-clause, not just the umbrella clause), e.g , new Annex “X”.
13CHANGE REQUEST Other core specifications Test specifications Other specs affected : Other core specifications Test specifications O&M SpecificationsTick "yes" box if any other specifications are affected by this change. Else tick "no". You MUST fill in one or the other. List here the specifications which are affected or the CRs which are linked.Other comments : Enter any other information which may be needed by the group being requested to approve the CR. This could include special conditions for its approval which are not listed anywhere else above.
14CHANGE REQUEST CR 4 rev 1 to 23.456 CR 4 rev 2 to 23.456 For example, a CR to TS may be revised twice during the course of discussions in the WG before it is agreed; the wording “Revision of Tdoc S2-09xxxx” should appear under the (new) Tdoc number of the revised CR.CR 4 rev 1 toCR 4 rev 2 toCR 4 to
15CHANGE REQUEST CR 4 rev 2 to 23.456 CR 5 rev 1 to 23.456 Prior to each TSG plenary, all CRs against a given specification, or a given work item, are gathered together by the Secretary of the WG responsible for the spec. In case, the Secretary cleans the front page, e.g. accepts all revision marks, and checks that the fields are correctly filled in.A single Tdoc is created, with a cover page introducing each individual CR (it is suggested to group no more than ~20 CRs per Tdoc).CR 4 rev 2 toCR 5 rev 1 toCR 6 to
