16 16 TS V ( ) Foreword This Technical Specification (TS) has been produced by the 3 rd Generation Partnership Project (). The present document specifies the stage 2 description for the third phase (see TS [2]) of the Customized Applications for Mobile network Enhanced Logic (CAMEL) feature within the system. The contents of present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will then 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 greater 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.

17 17 TS V ( ) 1 Scope The present document specifies the stage 2 description for the third phase (see TS [2]) of the Customized Applications for Mobile network Enhanced Logic (CAMEL) feature which provides the mechanisms to support services of operators which are not covered by standardized GSM services even when roaming outside the HPLMN. The 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. In the present document, the GSM Service Control Function (gsmscf) is treated as being part of the HPLMN. The regulatory environment in some countries may require the possibility that the gsmscf and the HPLMN are controlled by different operators, and the gsmscf and the HPLMN are therefore distinct entities. In the third phase the CAMEL feature supports: - mobile originated and forwarded calls; - mobile terminating calls; - any time interrogation; - active location information retrieval; - suppression of announcements; - announcements, in band user interaction; - charging features; - supplementary service invocation notifications; - USSD interaction with the gsmscf; - rth American carrier selection; - Mobility Management event notifications; - change of Calling Line Identification Presentation Indicator for an MO call to restricted; - SoLSA; - Subscribed dialled services; - Serving network dialled services; - MO SMS; - GPRS data transmission; - Mobility management; - tification to CSE of change of subscriber data; - Any Time Modification; - Any Time Interrogation of subscription Information; - T-BCSM in the VMSC and terminating AoC; - Interworking with Location Services; - Multiple Subscriber Profile; - Active Location Retrieval; - Call Gapping.

18 18 TS V ( ) te that CAMEL is not applicable to Emergency Setup (TS 12), i.e., in case an Emergency call has been requested the gsmssf shall not be invoked. The mechanism described in the present document addresses especially the need for information exchange between the VPLMN or IPLMN and the HPLMN for support of operator specific services. Any user procedures for the control of operator specific services are outside the scope of the present document. Subscribers who have subscribed to operator specific services and therefore need the functional support of the CAMEL feature shall be marked in the HPLMN and VPLMN. In case a subscriber is marked to need CAMEL support, the appropriate procedures which provide the necessary information to the VPLMN or the HPLMN are invoked. It is possible for the HPLMN to instruct the VPLMN or IPLMN to interact with a gsmscf which is controlled by the HPLMN. The specification of operator specific services is outside the scope of the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

As such, it identifies a set of basic call activities in a GMSC or MSC/VLR and shows how these activities are joined together to process a basic call Call Control Function (CCF): CCF is the Call Control Function in the network that provides call/service processing and control (see ITU-T Recommendation Q.1224) Detection Points (DP): points in processing at which notifications (to the service logic) can occur and transfer of control (to the gsmscf) is possible are called Detection Points (DPs) Dialled Service CAMEL Subscription Information (D-CSI): D-CSI identifies the subscriber as having originating CAMEL dialled services Forwarding MSC: MSC which is either an MSC invoking a GSM standardized call forwarding or call deflection service; or an MSC invoking a Camel based call forwarding service Gateway MLC (GMLC): functional entity that allows external LCS Clients to request real-time information about a Mobile Station. The information that can be requested from the GMLC is: - location of Mobile Station. See TS [17] and TS [18] for information on the GMLC. Geodetic Information: information defining the location of a mobile station, coded according to ITU-T Recommendation Q.763. The derivation of this information from other information defining the location of a mobile station is a network operator option. If an entity derives the geodetic information it shall also provide the equivalent geographical information Geographical Information: information defining the location of a mobile station, coded according to TS GPRS CAMEL Subscription Information (GPRS-CSI): GPRS-CSI identifies the subscriber as having GPRS CAMEL services.

21 21 TS V ( ) GPRS Dialogue: dialogue between the gprsssf and the gsmscf. A single gprsdialogue may consist of one or more TCAP dialogues. Only one TCAP dialogue shall exists at one point in time for one gprsdialogue GPRS Service Switching Function (gprsssf): functional entity that interfaces the SGSN to the gsmscf. The concept of the gprsssf is derived from the IN SSF, but uses different triggering mechanisms because of the nature of the mobile network GPRS Session: GPRS session starts when the GPRS subscriber attaches to the GPRS data network. It ends when the GPRS subscriber detaches from the GPRS data network GSM Service Control Function (gsmscf): functional entity that contains the CAMEL service logic to implement OSS. It interfaces with the gsmssf, the gsmsrf, the GMLC and the HLR GSM Service Switching Function (gsmssf): functional entity that interfaces the MSC/GMSC to the gsmscf. The concept of the gsmssf is derived from the IN SSF, but uses different triggering mechanisms because of the nature of the mobile network GSM Specialised Resource Function (gsmsrf): functional entity which provides various specialized resources. It interfaces with the gsmscf and with the MSC. This entity is defined in ITU-T Recommendation Q.1224 [30] with variations defined in the specification Location Information: indicates the location of the Mobile Station. The provision of location information is independent of the MS status. As part of the location information, an indication of the age of this information may be delivered Mobile Station State: similar to Subscriber State, but associated only with a Mobile Station, not with a subscriber Mobility Management event CAMEL Subscription Information (M-CSI): M-CSI identifies the subscriber as having Mobility Management event notification CAMEL services NA (rth American): prefix attached to certain information items used by rth American PLMNs in connection with routing a call to a preferred or dialled long distance carrier Network CAMEL Service Information (N-CSI): N-CSI identifies services offered on a per-network basis by the serving PLMN operator for all subscribers Originating Basic Call State Model (O-BCSM): originating half of the BCSM. The O-BCSM corresponds to that portion of the BCSM associated with the originating party Originating CAMEL Subscription Information (O-CSI): O-CSI identifies the subscriber as having originating CAMEL services Point In Association (PIA): PIAs identify MSC/VLR/ SGSN activities associated with one or more basic association/connection states of interest to OSS service logic instances Point In Call (PIC): PICs identify MSC/VLR (GMSC) activities associated with one or more basic call/connection states of interest to OSS service logic instances Service Key: Service Key identifies to the gsmscf the service logic. The Service Key is administered by the HPLMN, and is passed transparently by the VPLMN/IPLMN to the gsmscf. The Service Key is a part of the T/O/VT/D/GPRS/SMS/M-CSI Serving MLC: functional entity that performs location information retrieval Short Message Service CAMEL Subscription Information (SMS-CSI): SMS-CSI identifies the subscriber as having MO SMS CAMEL services Short Message Service Centre (SMSC): also abbreviation SC is used for SMSC Subscriber State: see TS [2]. Supplementary Service tification CAMEL Subscription Information (SS-CSI): SS-CSI identifies the subscriber as having supplementary service invocation notification CAMEL services Terminating Basic Call State Model (T-BCSM): terminating half of the BCSM. The T-BCSM corresponds to that portion of the BCSM associated with the terminating party
