Designator Foreword This Global System for Mobile communications Technical Specification (GTS) was produced by the Special Mobile Group (SMG) Techni
23、cal Committee of the European Telecommunications Standards Institute (ETSI). This GTS defines the stage 1 description for the first phase of the CAMEL feature (Customised Applications for Mobile network Enhanced Logic) which provides the mechanisms to support seMces consistently independently of the
24、 serving network within the digital cellular telecommunications system. The contents of this GTS are subject to continuing work within SMG and may change following formal SMG approval. Should SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of releas
25、e date and an increase in version number as follows: Version 5.x.y where: 5 indicates Release 1996 of GSM Phase 2+ x the second digit is incremented for all changes of substance, .e. technical enhancements, corrections, updates, etc. the third digit is incremented when editorial only changes have be
26、en incorporated in the specification. y Introduction The present document includes references to features which are not pari 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
27、the particular feature. The following table lists all features that were introduced after Release 96. STD.ETS1 GSM 02.78-ENGL 1999 - 3400855 0390442 832 m Page 7 GSM 02.78 version 5.6.0 Release 1996: March 1999 I Scope This standard specifies the stage 1 description for the first and the second phas
28、e of the CAMEL feature (Customised Applications for Mobile network Enhanced Logic) which provides the mechanisms to support services consistently independently of the serving network. The CAMEL features shall facilitate service control of operator specific services external from the serving PLMN. Th
29、e CAMEL feature is a network feature and not a supplementary service. It is a tool to help the network operator to provide the subscribers with the operator specific services even when roaming outside the HPLMN. CAMEL is developed in phases. The following phases exist: - - CAMEL phase 1. This is the
30、 default phase in this specification. CAMEL phase 2. It is characterised where necessary with the formal designation - $(CAMEU$) and sometimes with an indication of CAMEL phase 2. - $(CAMEU$) The CAMEL feature is applicable: - - The mechanism described addresses especially the need for information e
31、xchange among the VPLMN, HPLMN and the CAMEL Service Environment (CSE) for support of such operator specific services. Any user procedures for operator specific services are outside the scope of this standard. This specification describes the interactions between the functions of the VPLMN, HPLMN, I
32、PLMN and the CSE. to mobile originated and mobile terminated call related activities; and, as a CAMEL phase 2 function, to supplementary service invocations - $(CAMEU$) The second phase of CAMEL enhance the capabilities of phase 1 and are included in this standard. Following new topics are added: -
33、- - - - New trigger detection points were defined. It is possible to interact with a user using announcements, voice prompting and information collection via in band interaction or USSD interaction. It is possible to control the call duration and to transfer e-values from a serving node to the mobil
34、e station. The CSE can be informed about the invocation of GSM Supplementary services (ECT, CD, MPTY). For easy post processing, charging information from a serving node can be integrated in normal call records. Detailed information can be found in the respective sections. 2 Normative references Thi

I51 3 Definitions and abbreviations Operator Specific Service (OS): Any service offered on a PLMN that is not standardised by the GSM specifications. Interrogating PLMN (IPLMN): This is the PLMN that performs the interrogation o
40、f the HPLMN for information on the treatment of a terminating call. CAMEL Service Environment (CSE): A CSE is a logical entity which processes activities related to Operator Specific Services (OSS). Service event: A specific event of a GSM process that may be used as part of an operator specific ser
41、vice. Service procedure: A part of the CAMEL feature to be used to detect a specific CAMEL service event. CAMEL Subscription Information (CSI): The CSI identifies that CAMEL support is required for the subscriber and the identities of the CSEs to be used for that support. The CSI also contains infor
42、mation related to the OSS of the subscriber, e.g. Service Key. Location Information: The location information shall be an identification of the location of the served subscriber. The following location information should be sent to the CSE (if available): - Geographical information (longitude and 1a
43、titude)when Cell ID or Location Area Code is known) this may be calculated as the nominal central point of the cell or of the location area; alternative mechanisms for determining latitude and longitude may also be supported. The resolution and accuracy of the indicated location information may also
44、 be provided. Cell ID indicates the global identity of the current or last cell which the subscriber is using or has used. The VPLMN shall update the stored Cell ID at establishment of every radio connection and whenever the subscriber is handed over between cells. - - - VLR number is the number of
45、the serving VLR stored in the HPLMN. Location status indicates whether or not the location information has been confirmed by radio contact. If the location information has not been confirmed by radio contact a time stamp is sent indicating the time elapsed since the last radio contact with the subsc
46、riber. Location number is the number received on the incoming circuit (for an incoming call) or to be sent on the outgoing circuit (for an outgoing call). - Service Key: An identifier of the OSS which shall be transparent to the IPLMNNPLMN. Subscriber Status: An indication of the status of a subscri
47、ber, determined by the state of the subscribers MS. The subscriber status can take one of three values: - - CAMEL-busy: the MS is engaged in a mobile-originated or mobile-terminated circuit-switched call. Network determined not reachable: the network can determine from its internal data that the MS
48、is not reachable. This includes detached and purged mobile stations. - Assumed idle: any MS that is not CAMEL-busy or network determined not reachable.

At a service event, the IPLMN or VPLMN may suspend the process and make contact with a CSE to ask for instructions or to send a notification. At this time the IPLMN or VPLMN shall send to the CSE the information listed in this specificatio
