13、.0.0: May 1996 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS provides a mechanism giving reliable transfer of sig
14、nalling messages within the digital cellular telecommunications system (Phase 2/Phase 2+). This GTS is a TC-SMG approved GSM technical specification version 5, which contains GSM Phase 2+ enhancements/features. GTS are produced by TC-SMG to enable the GSM Phase 2 + specifications to become publicly
15、available, prior to submission for the formal ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2 + specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile c
16、ommunications. The contents of this GTS are subject to continuing work within TC-SMG and may change following formal TC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as foll
17、ows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the specification; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. NOTE: TC-SMG has produced documents which give
18、the technical specifications for the implementation of the digital cellular telecommunications system. Historically, these documents have been identified as GSM Technical Specifications (GSM-TSs). These TSs may have subsequently become I-ETSs (Phase l), or ETSs/ETSI Technical Reports (ETRs) (Phase 2
19、). TC-SMG has also produced ETSI GSM TSs which give the technical specifications for the implementation of Phase 2+ enhancements of the digital cellular telecommunications system. These version 5.x.x GSM Technical Specifications may be referred to as GTSs. ETSI GSM*04.63 96 m 3400855 Olt09814 705 m

29、k. Support of the PDSS2 protocol is optional in the mobile station and in the network. If a mobile station supports the PDSSI protocol, it must support it on both the main and the slow associated data link. 5 Main concepts This Technical Specification specifies the protocols for connection managemen
30、t of packet data on signalling channels which is applied on the air interface: the - - PDSS1 (Packet Data on Signalling channels Service 1) protocol, and the PDSS2 (Packet Data on Signalling channels Service 2) protocol. Both are protocols of the Connection Management (CM) sublayer (see TS GSM 04.07
31、). PDSS1 and PDSS2 transactions can be active in parallel to other CM transactions. A PDSSI transaction may be initiated by the mobile station or the network. A PDSS2 transaction shall only be initiated by the mobile station. This Technical Specification describes the PDSSl and PDSS2 protocols with
32、regard to two peer entities, one in a mobile station, the other one in the network. The call control entities are described as communicating finite state machines which exchange messages across the radio interface and communicate internally with other protocol (sub)layers.(see note In the model, for
33、 PDSS1, for each Transaction Identifier (TI) value there are two protocol entities in the mobile station and two protocol entities in the network: one which may originate a transaction and one which may use the transaction originated bt its peer entity; the protocol entity receiving messages with a
34、given TI and TI flag value x may send messages with equal TI value and with TI flag value (1-x) mod 2. The originator uses TI flag value O. A protocol entity is idle (also called: in the idle phase) until it has received a message from its peer entity or lower or higher layers have passed an abstrac
35、t service primitive to it. NOTE: Text not yet approved for this version In particular, the - PDSS1 protocol uses the MM and RR sublayer specified in TS GSM 04.08, and the - PDSS2 protocol uses the RR sublayer specified in TS GSM 04.08. This description in only normative as far as the consequential e
36、xternally observable behaviour is concerned. Certain sequences of actions of the two peer entities compose “elementary procedures“ which are used as a basis for the description in this Technical Specification. These elementary procedures are defined in section 6 and 7. NOTE: Whereas PDSS1 provides c
37、onnections between mobile station and MSC, PDSS2 provides connections between the mobile station and the PDSS2 support node, see TS GSM 03.63. The mobile station receives on lower sublayers information from the network whether the mobile station is allowed to establish a PDSS1 and/or PDSS2 connectio
38、n. The network is informed by the mobile station in the classmark whether the mobile station supports PDSS1 and/or PDSS2. ETSI GSM*Oi.b3 9b = 3400855 0109817 414 Page 9 GSM 04.63 Version 5.0.0: May 1996 The PDSS1 and PDSS2 protocols may use the main signalling link or the slow associated signalling
39、link for communication, always on the SAP with SAPI=O and in acknowledged mode (for the definition of these terms, see TS GSM 04.06). It is informed by the network whether it is allowed to establish a PDSS1 and/or PDSS2 connection by sending the SETUP and/or the IMMEDIATE SETUP message on the main s
40、ignalling link andlor slow associated signalling link. If the mobile station supports PDSSl and/or PDSS2, it shall be able to receive messages of the supported protocol(s) on both data links. Once a protocol entity in the mobile station has received a message, the mobile station shall send any furth
41、er message pertaining to the same transaction on the data link on which it had received the last message. 6 Elementary procedures for PDSS1 6.1 Overview The elementary procedures for PDSSI may be grouped into the following classes: - PDSS1 establishment procedures - PDSS1 termination procedures - PD
42、SS1 information phase procedures. 6.2 Procedures for establishment of a PDSS1 connection The PDSSl protocol entity in the mobile station or network in the idle phase shall on request of higher layers to establish a connection, analyse the request: the request contains all information necessary for t
43、he SETUP message and an indication whether the main or slow associated data link is to be used. The PDSS1 protocol entity shall then verify whether 1) use of the indicated link for PDSSl is possible and allowed and ask the MM sublayer whether 2) establishment of a PDSS1 connection is possible and al
44、lowed. - If one of these conditions is not fulfilled, the request is rejected. - If the MM connection establishment is possible and allowed and the use of the indicated link is possible and allowed, the PDSS1 protocol entity asks the MM sublayer to establish an MM connection. The request contains a
45、SETUP message to be transferred to the peer entity. The request from higher layers may already contain data to be transferred which does not exceed a maximum allowed length. In this case the data is included in the SETUP message. - If the MM connection establishment fails or is rejected, the PDSS1 p
46、rotocol entity aborts the establishment and gives an appropriate information to higher layers; it then returns to the idle phase. An idle PDSS1 protocol entity shall on receipt of a SETUP message inform higher layers. If the SETUP message contained a data part, it passes the data part to higher laye
47、rs and then continues as follows: - If higher layers accept the establishment, the PDSS1 protocol entity shall send a SETUP ACKNOWLEDGE message to its peer entity and enter the PDSSI information transfer phase. The acceptance from higher layers may already contain data to be transferred which does n
48、ot exceed a maximum allowed length. In this case the data is included in the SETUP ACKNOWLEDGE message. - If higher layers reject the establishment, the PDSS1 protocol entity shall send a RELEASE COMPLETE message with appropriate cause to its peer entity. When a PDSS1 has transferred a SETUP message
49、 to its peer entity and receives as an answer a SETUP ACKNOWLEDGE message, it informs higher layers and enters the PDSS1 information transfer phase.

If during the establishment of a PDSS1 connection a lower layer failure occurs, the PDSS1 protocol entity shall abort the establishment and inform hi
