Introduction In the present document is described additions, deletions, and changes made to ITU-T Recommendation H.324 10 with annex C for the purpose of

23、using that recommendation as a basis for the technical specification for circuit switched multimedia service in 3GPP networks. The present document does not address call setup procedures, but references to the specifications which cover call setup are found in 3GPP TS 26.110 11. ETSI ETSI TS 126 111

24、 V15.0.0 (2018-07)53GPP TS 26.111 version 15.0.0 Release 151 Scope In ITU-T Recommendation H.324 10 with annex C describes a generic multimedia codec for use in error-prone, wireless networks. The scope of the present document are the changes, deletions, and additions to those texts necessary to ful

25、ly specify a multimedia codec for use in 3GPP networks. Note that this implicitly excludes the network interface and call setup procedures. Also excluded are any general introductions to the system components. 2 References The following documents contain provisions which, through reference in this t

26、ext, 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 specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.

38、. 5 Document structure The structure of H.324 10 is followed in the present document. Where there are no differences in a specific section, that section is skipped. Where differences are minor, only the differences are described. Where major differences exist, the section is rewritten in the present

39、 document. It is important to note that for wireless terminals, Annex C of H.324 10 supersedes respective portions of the main body of H.324 10 For the present document, these modifications are treated as if they are part of the main body of H.324 10 Therefore, a reader must keep in mind both the ma

40、in body and Annex C of H.324 10 when reading the present document. 6 Functional requirements 6.1 Required elements 3G-324M implementations are not required to have each functional element except a wireless interface, H.223 1 with Annex A and B multiplex, and H.245 6 version 3 or later versions for s
