18、cket Switched Public Data NetworlIntegrated Services Digital Network (PSPDN/ISDN) for the support of packet services in GSM PLMNs. In the GSM PLMN context the packet services are associated with bearer services and are described in GSM 02.02. The generally defined GSM PLMN user-network access as def

19、ined in the respective GSM specifications (see references) forms the basis for defining the particularities for the provision of packet services to the GSM PLMN subscribers. Network internal interfaces for the support of packet services in the pan-European ISDN are defined in ETSI standards, which a

20、re also taken as a basis. User-network access and network internal interfaces are defined to provide the packet services. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. 0 References are either specific (id

These terms refer to information requirements necessary to support int

37、erworking functions, some of these terms will be identifiable with their use in other specifications. For the purposes of the present document, the following definitions apply: bearer capability information: Specific information defining the lower layer characteristics required within the network. l

38、ower layer capability information: Information defining the lower layer characteristics of the terminal. higher layer capability information: Information defining the higher layer characteristics of a teleservice active on the terminal. protocol identifier: Information defining the specific protocol

39、s 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: Detection of the situation, where a call, which has left the originating network, re-appears at the

40、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 characteristics of the connection identified by the following setting of the respective parameters of the BC-IE: -

41、- 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 PH inserts - irrespective of being accessed by a home or a foreign roaming subscriber - into the “ca

42、lling 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 B“: A packet connection shall be used for accessing the packet service (according to ETS 300 099), with the significant Characteristics of the connection identified

43、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 number is a special E.164 number of the HPLMN which indicates to the HPLMN that, in case of an access to

44、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 when the subscriber is in the HPLMN or in the VPLMN. packet mode services via PSTN (X.32): A circuit

45、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 Capability Information Element in access from a PLMN: - - information transfer capability = 3,l kHz exPLMN;

46、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 when leaving his home PLMN (HPLMN) and logged-in there. basic MSisdn: The MSisdn stored in VLR for a vi

47、siting mobile subscriber. PSPDN port: Unit providing incoming/outgoing demand access to a PSPDN (X.32).
