25、 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 substance, i.e. technical enhancements, cor

ETSI ETSI TS 148 006 V13.0.0 (2016-01)63GPP TS 48.006 version 13.0.0 Release 131 Scope The present document is split into four parts, clauses 4 to 6 dealing with the MTP, clau

27、se 6a dealing with M3UA/SCTP, clause 7 dealing with interface functions towards higher layers and clauses 8 to 10 dealing with the SCCP and its use. The MTP provides a mechanism giving reliable transfer of signalling messages. Clauses 4 to 7 of the present document deal with the subset of the MTP th

28、at can be used between an BSS and an MSC, which is compatible with a full MTP. The M3UA/SCTP provides a mechanism giving reliable transfer of signalling messages over an IP network. The SCCP is used to provide a referencing mechanism to identify a particular transaction relating to for instance a pa

29、rticular call. Clauses 8 to 10 identify the SCCP subset that should be used between a BSS and an MSC. The SCCP can also be used to enhance the message routing for (for instance) operations and maintenance information. 2 References The following documents contain provisions which, through reference i

42、ion 13.0.0 Release 133 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: E1: link employs 32 Pulse Code Modulation signals (timeslots) at 64 kbits/s. The 32 timeslots consist of 30 voice (or signalling) channels and 2 c

43、ommon signalling channels. The output bit rate is 2 048 Mbits/s. T1: link employs 24 Pulse Code Modulation signals (timeslots) at 64 kbits/s. (T1 interface can alternatively use signalling at 56 kbits/s). The output bit rate is 1 544 Mbits/s. (A frame consists of 193 bits, (8 x 24) + 1, as one bit i

44、s used for synchronization. The frame repeats 8,000 times per second.). 3.2 Abbreviations For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 apply. 4 Field of application a) The present document is applicable to the signalling between radio subsystems (BSS) and mobil

45、e switching centres (MSCs) in GSM PLMNs. It provides a minimum set of MTP, or in the case of IP-based signalling transport - M3UA and SCTP, requirements that may be implemented at a BSS or MSC, whilst maintaining compatibility with the implementation of a full specification of the MTP (M3UA/SCTP). b

46、) For MTP signalling transport usage, the Technical Specification defines the interface at the 64 kbits/s boundary to the BSS or MSC and applies primarily for digital access arrangements, the use of analogue arrangements isan option for PLMN operator. Also, the Technical Specification defines the in

47、terface at the 56 kbits/s boundary to the BSS or MSC for T1 links. c) The security of signalling links is a PLMN operator concern , however it is recommended that in the case where more than one multiplex system is required and security reasons dictate the use of a multiple link linkset, then each s

48、ignalling link should be assigned in a different multiplex system. It is however noted that this is of little benefit if diversity of routing of the multiplexes is not used. d) Both associated and quasi-associated modes of signalling between the BSS and the MSC are allowed. In case of quasi-associat

49、ed mode the STP functionality is provided outside the BSS. Future evolution or economic reasons applicable to the interface may however make the use of STP working at the BSS attractive, in which case some of the simplifications in this paper will not apply. e) A variety of information types may be supported by the signalling system, e.g. relating to circuit switched call control and packet communi
