6 Subscriber Location and State retrieval
23.2783GPPCustomised Applications for Mobile network Enhanced Logic (CAMEL) Phase 4IM CN InterworkingRelease 17Stage 2TS
Support of the procedures described in this clause in CAMEL Phase 4 is a network operator option.
6.1 Architecture
The architecture for the subscriber location and state retrieval described in the clause 11 in 3GPP TS 23.078 Rel‑99 [4] for the HLR and the gsmSCF applies for the HSS and the gsmSCF.
6.2 Procedures for CAMEL
6.2.1 Any Time Interrogation
The description of the procedure in 3GPP TS 23.078 Rel‑99 [4] applies for the Any Time Interrogation in the HSS.
6.3 Description of information flows
This clause contains the detailed description of the information flows used by CAMEL for the retrieval of information about the location and state of a subscriber.
Each Information Element (IE) is marked as Mandatory (M), Conditional (C), Specific conditions (S), mutually Exclusive (E) or not applicable (-).
An ‘M’ IE shall always be included. A ‘C’ IE shall be included if the sending entity has the necessary information to populate the IE. The conditions for the inclusion of an ‘S’ IE are shown in the ‘Description’ column of the definition table. When a set of ‘E’ IEs is shown in the definition of an Information Flow or compound IE, only one of those IEs may be included. A ‘‑’ IE shall always be omitted. This categorization is a functional classification, i.e. it defines the requirements for the stage 2 information. It is not a stage 3 classification to be used for the ASN.1 syntax of the protocol.
The following principles apply for the handling of the IEs by the receiving entity:
– The gsmSCF may silently discard any IE which it does not functionally support.
– The GMLC shall return an error if it does not functionally support an IE which it receives.
Details of errors and exceptions to these rules are specified in 3GPP TS 29.002 [9].
6.3.1 gsmSCF to HSS information flows
6.3.1.1 Any Time Interrogation Request
6.3.1.1.1 Description
This IF is used to request information (any one or more of subscriber state, subscriber location, IMEI & software version, MS classmark information for the CS domain and GPRS MS classmark information) from the HSS at any time. The IF from the gsmSCF to the HLR is specified in 3GPP TS 23.078 Rel‑99 [4]. The IF is also applied to the interface between the gsmSCF to the HSS.
6.3.2 HSS to gsmSCF information flows
6.3.2.1 Any Time Interrogation ack
6.3.2.1.1 Description
This IF is used by the HSS to provide the requested subscriber location and/or subscriber state information to the gsmSCF. The IF from the HLR to the gsmSCF is specified in 3GPP TS 23.078 Rel‑99 [4]. The IF is also applied to the interface between the gsmSCF to the HSS.
