The present document specifies the proc

24、edures used at the radio interface core network protocols within the 3rdgeneration mobile telecommunications system and the digital cellular telecommunications system. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Sho

25、uld 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 where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greate

26、r indicates TSG approved document under change 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. Introduction The presen

27、t 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 contain a marker (see table below) relevant to the particular feature. ETSI ETSI TS 123 108 V15.0.0 (2018-06)6

28、3GPP TS 23.108 version 15.0.0 Release 151 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), Mobility Management (MM), and Session Management (SM). When the notations for “further study“ or “FS“ or “FFS“

29、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 channels of the radio interface. The control channels are described in 3GPP TS 44.003 16. The structured fun

30、ctions 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 procedures currently described in the present document are for the call control of circuit-switched connections

31、, 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 supplementary services. 3GPP TS 24.011 22 contains functional procedures for support of point-to-point sho

32、rt 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 (RLC/MAC) of packet data physical channels. 3GPP TS 44.018 80 contains the procedures for the RR protocol.

33、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 functions and protocols described in this Technical Specification. The terms “data link layer“ and “layer

34、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 TS 44.003 16. They use the functions and services provided by layer 2 defined in 3GPP TS 44.005 18 and 3GP

35、P 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 is used to describe the layer 3 procedures. The basic building blocks are “elementary procedures“ provided

36、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 specific sequences of elementary procedures. The term “structured procedure“ is used for these sequences. 1.4 Test

37、 procedures Test procedures of the GSM radio interface signalling are described in 3GPP TS 51.010 39 and 3GPP TS 51.02x series. 1.5 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 inf

41、; 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 of VBS (Voice Broadcast Service) calls or VGCS (Voice Group Call Service) calls. Two service access points

42、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 including user-user information; ii) SAPI 3: supports the transfer of user short messages. Layer 3 selects th

43、e 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 for each individual message. 1.6 Overview of control procedures 1.6.1 List of procedures The following pro

44、cedures are specified in the Technical Specification: a) Clause 4 specifies elementary procedures for Mobility Management: - mobility management common procedures (subclause 4.3); - TMSI reallocation procedure (subclause 4.3.1); - authentication procedure (subclause 4.3.2); - identification procedur
