The present document specifies the Radio Link Protocol (RLP) for circ

27、uit switched data transmission within the 3GPP system. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying ch

28、ange of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of subs

29、tance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 124 022 V15.0.0 (2018-07)63GPP TS 24.022 version 15.0.0 Release 151 Scope The present document specifies the Radio Link Pro

30、tocol (RLP) for circuit switched data transmission within a PLMN. RLP covers the Layer 2 functionality of the ISO OSI Reference Model (ISO/IEC 7498 22). It is based on ideas contained in ISO/IEC 3309 21, ISO/IEC 4335 20 and ISO/IEC 7809 26 (HDLC of ISO) as well as ITU-T Recommendation X.25 30 and Q.

31、92x (LAP-B and LAP-D of ITU, respectively.) RLP has been tailored to the special needs of digital radio transmission. RLP provides to its users the OSI Data Link Service (ISO/IEC 8886 24). RLP is intended for use with non-transparent data-transfer. Protocol conversion may be provided for a variety o

32、f protocol configurations. Those foreseen immediately are: - character-mode protocols using start-stop transmission (IA5); - X.25 LAP-B. For reasons of better presentation, material about protocol conversion has been placed within those Specifications concerned with the relevant Terminal Adapters, i

33、.e. 3GPP TS 27.002 10 for the asynchronous case and 3GPP TS 27.003 11 for the synchronous case. Care must be taken that that material also applies to Interworking Functions; see 3GPP TS 29.007 13. The present document is valid for a PLMN in A/Gb mode as well as in Iu mode. If text applies only for o

34、ne of these systems it is explicitly mentioned by using the terms “A/Gb mode“ and “Iu mode“. Please note, that the Gb interface does not play any role in the scope of the present document although the term “A/Gb mode“ is used. 2 References The following documents contain provisions which, through re

35、ference 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 specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest v

36、ersion applies.
