23、nt 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 change of release date and an increase in version number as follows: Version x.y.z

Introduction The present document includes references to features which are not part of the Phase 2+ Release 96 of the GSM Technical specifications. All subclauses which were changed as a result of these features con

26、tain a marker (see table below) relevant to the particular feature. ETSI ETSI TS 123 108 V14.0.0 (2017-04)63GPP TS 23.108 version 14.0.0 Release 141 Scope The present document specifies the procedures used at the radio interface (Reference Point Um, see 3GPP TS 24.002 15) for Call Control (CC), Mobi

27、lity Management (MM), and Session Management (SM). When the notations for “further study“ or “FS“ or “FFS“ are present in the present document they mean that the indicated text is not a normative portion of this standard. These procedures are defined in terms of messages exchanged over the control c

28、hannels of the radio interface. The control channels are described in 3GPP TS 44.003 16. The structured functions and procedures of this protocol and the relationship with other layers and entities are described in general terms in 3GPP TS 24.007 20. 1.1 Scope of the Technical Specification The proc

29、edures currently described in the present document are for the call control of circuit-switched connections, session management for GPRS services, mobility management and radio resource management for circuit-switched and GPRS services. 3GPP TS 24.010 21 contains functional procedures for support of

30、 supplementary services. 3GPP TS 24.011 22 contains functional procedures for support of point-to-point short message services. 3GPP TS 24.012 23 contains functional description of short message - cell broadcast. 3GPP TS 44.060 76 contains procedures for radio link control and medium access control

31、(RLC/MAC) of packet data physical channels. 3GPP TS 44.018 80 contains the procedures for the RR protocol. 3GPP TS 24.008 81 contains the procedures for the CN protocols. 3GPP TS 44.071 23a contains functional descriptions and procedures for support of location services. NOTE: “layer 3“ includes the

32、 functions and protocols described in this Technical Specification. The terms “data link layer“ and “layer 2“ are used interchangeably to refer to the layer immediately below layer 3. 1.2 Application to the interface structures The layer 3 procedures apply to the interface structures defined in 3GPP

33、 TS 44.003 16. They use the functions and services provided by layer 2 defined in 3GPP TS 44.005 18 and 3GPP TS 44.006 19. 3GPP TS 24.007 20 gives the general description of layer 3 including procedures, messages format and error handling. 1.3 Structure of layer 3 procedures A building block method

34、is used to describe the layer 3 procedures. The basic building blocks are “elementary procedures“ provided by the protocol control entities of the three sublayers, i.e. radio resource management, mobility management and connection management sublayer. Complete layer 3 transactions consist of specifi

35、c sequences of elementary procedures. The term “structured procedure“ is used for these sequences. 1.4 Test procedures Test procedures of the GSM radio interface signalling are described in 3GPP TS 51.010 39 and 3GPP TS 51.02x series. ETSI ETSI TS 123 108 V14.0.0 (2017-04)73GPP TS 23.108 version 14.

36、0.0 Release 141.5 Use of logical channels The logical control channels are defined in 3GPP TS 45.002 32. In the following those control channels are considered which carry signalling information or specific types of user packet information: i) Broadcast Control CHannel (BCCH): downlink only, used to

37、 broadcast Cell specific information; ii) Synchronization CHannel (SCH): downlink only, used to broadcast synchronization and BSS identification information; iii) Paging CHannel (PCH): downlink only, used to send page requests to Mobile Stations (MSs); iv) Random Access CHannel (RACH): uplink only,

38、used to request a Dedicated Control CHannel; v) Access Grant CHannel (AGCH): downlink only, used to allocate a Dedicated Control CHannel; vi) Standalone Dedicated Control CHannel (SDCCH): bi-directional; vii) Fast Associated Control CHannel (FACCH): bi-directional, associated with a Traffic CHannel;

39、 viii)Slow Associated Control CHannel (SACCH): bi-directional, associated with a SDCCH or a Traffic CHannel; ix) Cell Broadcast CHannel (CBCH): downlink only used for general (not point to point) short message information. x) Notification CHannel (NCH): downlink only, used to notify mobile stations

40、of VBS (Voice Broadcast Service) calls or VGCS (Voice Group Call Service) calls. Two service access points are defined on signalling layer 2 which are discriminated by their Service Access Point Identifiers (SAPI) (see 3GPP TS 44.006 19): i) SAPI 0: supports the transfer of signalling information in

41、cluding user-user information; ii) SAPI 3: supports the transfer of user short messages. Layer 3 selects the service access point, the logical control channel and the mode of operation of layer 2 (acknowledged, unacknowledged or random access, see 3GPP TS 44.005 18 and 3GPP TS 44.006 19) as required

42、 for each individual message. 1.6 Overview of control procedures 1.6.1 List of procedures The following procedures are specified in the Technical Specification: a) Clause 4 specifies elementary procedures for Mobility Management: - mobility management common procedures (subclause 4.3); - TMSI reallo
