The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG mod the contents of the pre
29、sent document, it will be re-released by the TSG with an identiSling change 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 ch
30、ange control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. I n t rod uct ion The 07.10 multiplexer protocol operates between
31、 an MS and a TE and allows a number of simultaneous sessions over a normal serial asynchronous interface. Each session consists of a stream of bytes transferring various kinds of data; for instance, voice, fax, data, SMS, CBS, phonebook maintenance, battery status, GPRS, USSD etc. This permits, for
32、example, SMS and CBS to be transferred to a TE when a data connection is in progress. Many other combinations are possible including digital voice. It is, for instance, possible to transfer digital voice in combination with SMS. The multiplexer allows a complete system to be partitioned in a flexibl
33、e way between a MS and TE. The design of the multiplexer is flexible and independent of MS/TE platforms, and allows existing applications to work without any modifications. The multiplexer is designed, with special care for battery-powered devices, to include very important functionality such as pow
34、er saving control and priorities. It is also specially designed to require minimum processing power and memory consumption. The multiplexer is defined as a single mode with different options based on the IS0 HDLC standard (ISO/IEC 13239: 1997) although the basic option is not in accordance with HDLC
35、. In the basic option, the multiplexer does not make use of any transparency mechanism or error recovery method. The advanced option uses the IS0 HDLC standard transparency mechanism and gives the multiplexer an easy re- synchronisation method and the ability to operate over links which already use
36、DCl/DC3 (XON/XOFF) flow control. The advanced option also may include error-recovery for links subject to errors. In its basic option, the multiplexer is intended for use in situations where the link between MS and TE is of a very good quality and where the HDLC transparency mechanism (byte stuffing
37、) can not be implemented in the MS. If an MS supports the HDLC transparency mechanism, it shall be used by the multiplexer. The IS0 HDLC transparency mechanism must be used if loss of synchronisation may occur caused by, for example, data over-runs or under-runs. The error-recovery option should be
38、used in situations where the link is subject to errors. The multiplexer is based on a control channel. On this channel, management information is exchanged, such as parameter negotiation, power saving control information, testing, flow control, close down etc. The multiplexer is optional, but when s
39、upported, it is activated with the 07.07 AT+CMUX command. ETSI 3GPP TS 07.10 version 7.2.0 Release 1998 7 ETSI TS 101 369 V7.2.0 (2002-03) 1 Scope The scope of the present document is to define a multiplexing protocol between a mobile station and a terminal. The multiplexing protocol can be used to
40、send any data, for instance voice, SMS, USSD, fax etc. The present document describes the protocol, but not the commands or data transported with it. 2 Refe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document. Refere
41、nces 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. In the case of a reference to a 3GPP document (including a GSM do

45、tem The multiplexer provides mechanisms for conveying streams of data between TE and MS over a single start-stop framed, serial link. Figure 1 shows the arrangement of the various protocol levels and functions. The multiplexer layer provides multiplexing of data arranged in octet streams with no oth
46、er framing; if the structure of the data has to be conveyed, a convergence layer may be necessary. The present document defines some convergence layers, others may be added later.

48、 in the MS. For example, a PC application supporting SMS functions could be connected to the SMS handler in the MS via a multiplexer channel. The present document uses start-stop transmission with eight-bit characters. Communication between the two multiplexing entities takes place using frames cons

Each DLC may have individual flow control procedures for buffer management purposes and the aggregate link also has overall flow control mechanisms. DLCs have two modes of operation; Error-Recovery Mode (ERM) and non-error-recovery mode (non-ERM), the choice of mode is made when a DLC is established. DLCs using error recovery mode may exist on the same link as DLCs using non-error recovery mode. If the error-recovery mode (ERM
