This ETS identifies t
12、he Interworking Functions (IWFs) and requirements for the interworking between a GSM Public Land Mobile Network (PLMN) and a Packet Switched Public Data NetworWlntegrated Services Digital Network (PSPDNASDN) for the support of packet services in GSM PLMNs within the digital cellular telecommunicatio
13、ns system (Phase 2/Phase 2+). This ETS is a GSM technical specification version 5, which incorporates GSM Phase 2+ enhancementdfeatures to the version 4 GSM technical specification. The ETS from which this Phase 2+ ETS has evolved, is Phase 2 GSM ETC 300 603 + Amendment 1 (GSM 09.06 version 4.5.0).
14、The specification from which this ETS has been derived was originally based on CEPT documentation, hence the presentation of this ETS may not be entirely in accordance with the ETSVPNE Rules. The contents of this ETS are subject to continuing work within TC-SMG and may change following formal TC-SMG
15、 approval. Should TC-SMG modify the contents of this ETS it will then be resubmitted for OAP by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in th
16、e specification: x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. Transposition dates Date of adoption: Date of latest announcement of this ETS (doa): 4 April 1997 31 August 1997 Date of latest publication of new National Standa

18、cation Standard (ETS) identifies the Interworking Functions (IWFs) and requirements for the interworking between a GSM PLMN and a Packet Switched Public Data NetworWlntegrated Services Digital Network (PSPDNASDN) for the support of packet services in GSM PLMNs. In the GSM PLMN context the packet ser
19、vices are associated with bearer services and are described in GSM 02.02. The generally defined GSM PLMN user-network access as defined in the respective GSM specifications (see references) forms the basis for defining the particularities for the provision of packet services to the GSM PLMN subscrib
20、ers. Network internal interfaces for the support of packet services in the pan-European ISDN are defined in ETSI standards, which are also taken as a basis. User-network access and network internal interfaces are defined to provide the packet services. 2 Norm at i ve re fe re nces This ETS incorpora

37、e of the following terms within this ETS. These terms refer to information requirements necessary to support interworking functions, some of these terms will be identifiable with their use in other specificat ions. For the purposes of this ETS, the following definitions apply: bearer capability info
38、rmation: Specific information defining the lower layer characteristics required within the network. lower layer capability information: Information defining the lower layer characteristics of the terminal. higher layer capability information: Information defining the higher layer characteristics of
39、a teleservice active on the terminal. protocol identifier: Information defining the specific protocols utilised for the support of data transfer by a terminal. service profile: Set of values of the network default and user selectable attributes selected for a particular DTE identity. loop detection:
40、 Detection of the situation, where a call, which has left the originating network, re-appears at the originating network. GSM packet mode services “Use of X.31 case A“: A circuit connection shall be used for accessing the packet service (according to ETS 300 099), with the significant characteristic
41、s of the connection identified by the following setting of the respective parameters of the BC-IE: - - information transfer capability = unrestricted digital information; transfer mode = circuit mode. The issue of “loop detection“ is of no concern in the case of X.31 Case A (ETS 300 099) because the
42、 PH inserts - irrespective of being accessed by a home or a foreign roaming subscriber - into the “calling address“ of an outgoing X.25 “call request“ packet the address of the B-channel port. GSM packet mode services “Use of X.31 case BI: A packet connection shall be used for accessing the packet s
43、ervice (according to ETS 300 099), with the significant characteristics of the connection identified by the following setting of the respective parameters of the BC-IE: - - information transfer capability = unrestricted digital information; transfer mode = packet mode. service number: A service numb
44、er is a special E.164 number of the HPLMN which indicates to the HPLMN that, in case of an access to a PH X.31 case B, case A/B conversion is necessary. It is translated in the HPLMN into the actual E.164 number of the PH. The service number is used by the subscriber for the access of the PH case B
45、when the subscriber is in the HPLMN or in the VPLMN. packet mode services via PSTN (X.32): A circuit connection shall be used for accessing the packet service with the significant characteristics of the connection identified by the following setting of the respective parameters of the Bearer Capabil
46、ity Information Element in access from a PLMN: - - information transfer capability = 3,l kHz exPLMN; transfer mode = circuit mode. home PLMN: That GSM PLMN where the mobile subscriber has his subscription for mobile services. visited PLMN: That GSM PLMN on which the mobile subscriber is roamed to wh
47、en leaving his home PLMN (HPLMN) and logged-in there. basic MSisdn: The MSisdn stored in VLR for a visiting mobile subscriber PSPDN port: Unit providing incoming/outgoing demand access to a PSPDN (X.32).
