Yes, you must specify both when defining a package.

Dear all,
As I've been involved in 3GPP working group discussions regarding these 3GPP H.248 extentions, I'd like to provide some additional information/comments.
Although the 3GPP working groups view is that the 3GPP specification that contains the package definations in question is 95% complete. In my opinion these packages are not currently technically stable, during the last meeting the technical details for the encoding of the TFO package were not agreed.
Additionally, there is the open issue within 3GPP as to whether these 3GPP H.248 specifications should be specified for both text and binary encodings, or whether only one encoding type should be chosen.
However from reading clause 13.1 of H.248 (reproduced below) it seems that its a mandatory requirement to specify both a text and binary encoding of additional packages.
13.1 Packages The following considerations SHALL be met to register a package with IANA: 1) A unique string name, unique serial number and version number is registered for each package. The string name is used with text encoding. The serial number shall be used with binary encoding. Serial Numbers 60000-64565 are reserved for private use. Serial number 0 is reserved.
..."
Regards,
Kevin.

Dear all
FWIW, I agree entirely with Michelle's assessment. 3GPP specifications are *definitely* public documents (and we require that any document which is cited as a reference in a 3GPP specification is, in turn, a publicly available document).
On Tom Taylor's point about the stability of the specifications, we agreed at last week's working group meeting that the specifications are now ready for approval (which means that they will be brought under a formal change control system). They will be presented for approval at the meeting of Technical Specification Group Core network next week (14 - 16 March) in Palm
Springs, CA.
I hope this helps.
Best regards

3GPP is a public forum, and I believe their packages would be viewed as public. I'll note that it is desirable that the packages be considered technically stable (though perhaps subject to some editing and minor adjustment) before they are registered.
I've copied various parties for coordination purposes.

Tom,
Quick question. Which range should these packages be registered in? Do I need to ask the applicants if these are public or private?
From the RFC: Public packages MUST be given serial numbers in the range 0x0001 to 0x7fff. Private packages MUST be given serial numbers in the range 0x8000 to 0xffff.
Thanks for any help. If there is someone better to ask, please let me know. Don't want to bug you :)

Hi there
I am the editor for a 3rd Generation Partnership Project (3GPP) protocol specification which defines extensions to the H.248/MeGaCo protocol; I have pasted in a copy of the "Scope" clause of this specification below.
"The present document describes the protocol to be used on the Media Gateway Controller (MGC) - Media Gateway (MGW) interface. The Media Gateway Controllers covered in this specification are the MSC server and the GMSC server. The basis for this protocol is the H.248/MEGACO protocol as specified in ITU-T and IETF. The BICC architecture as described in ITU-T Q.1902 [7]-[11] and 3G TS 23.205 [3] defines the usage of this protocol. This specification describes the changes to H.248/MEGACO which are needed to handle 3GPP specific traffic cases. This is done by using the H.248/MEGCO standard extension mechanism. The present document is valid for a 3rd generation PLMN (UMTS) complying with Release 2000 and later. " We need to define three new packages for this specification, and as the custodians of the package identifiers you are the people I need to contact to ask for the package numbers!
I have pasted in the first part of the definition of each package below.
13.1.1 IuUP package. PackageID: 3giuup (0x####) [Editor's note: PackageID to be allocated by IANA] Version: 1 Extends: None This package identifies that the Iu User Plane is used for the termination. It also contains some parameters for the Iu User Plane functions in the MGW. The Iu User Plane is active in both directions independently of the Stream Mode. 13.1.2 Circuit Switched Data package PackageID: 3gcsd (0x####) [Editor's note: PackageID to be allocated by IANA] Version: 1 Extends: None This package contains the information needed to be able to support GSM and UMTS Circuit Switched Data from the media gateway. 13.1.3 TFO package PackageID: 3gtfoc (0x####) [Editor's note: PackageID to be allocated by IANA] Version: 1 Extends: None This package defines events and properties for Tandem Free Operation (TFO) control. TFO uses inband signalling and procedures for Transcoders to enable compressed speech to be maintained between a tandem pair of transcoders. This package allows an MGW which has inserted a transcoder to support TFO. Can you please let me know how I should go on from here to have the package numbers allocated? If you need any further information, please contact me.
Best regards
Ian Park
