Page 5ETS 300 529: March 1995 (GSM 03.11 version 4.8.1)ForewordThis European Telecommunication Standard (ETS) has been produced by the Special Mobile Group(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).This ETS defines the technical realization of supplementary services for the European digital cellulartelecommunications system (Phase 2).This ETS corresponds to GSM Technical Specification (GSM-TS) GSM 03.11 version 4.8.1.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 ETSI/PNE rules.Reference is made within this ETS to GSM-TSs (NOTE).Reference is also made within this ETS to GSM xx.xx series. The specifications in the series can beidentified, with their full title, within the normative reference Clause of this ETS by the first two digits oftheir GSM reference number e.g. GSM 09.xx series, refers to GSM 09.01, GSM 09.02, etc.NOTE:TC-SMG has produced documents which give the technical specifications for theimplementation of the European digital cellular telecommunications system. Historically,these documents have been identified as GSM Technical Specifications (GSM-TSs).These TSs may have subsequently become I-ETSs (Phase 1), or ETSs (Phase 2),whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are, for editorialreasons, still referred to in current GSM ETSs.SIST ETS 300 529 E1:2003

Page 7ETS 300 529: March 1995 (GSM 03.11 version 4.8.1)1General1.1ScopeThis technical specification describes the general aspects on how supplementary services in the GSMsystem are realized from a technical point of view.Description of technical realization for specific supplementary services can be found in GSM 03.8x and03.9x-series technical specifications.All supplementary services may require signalling on the radio path. Signalling procedures and messagesused are defined in the GSM 04.8x and 04.9x-series of technical specifications.For some supplementary services information needs to be transferred between the home location register(HLR), the visitor location register (VLR) and the mobile services switching centre (MSC). Signallingprocedures for such information transfer are defined in technical specification GSM 09.02.Definitions and descriptions of supplementary services are given in the GSM 02.8x and 02.9x-series oftechnical specifications.Definitions are given in technical specification GSM 02.04.NOTE 1:The technical specifications on the technical realization of supplementary services donot distinguish between subscriber, user and customer, since all three do not fully coverthe textual needs. Generally the term "subscriber" is used, even if this person is nothaving the subscription.NOTE 2:The terms "he", "his" and "him" are used as abbreviation of "he/she", "his/her" and"him/her" respectively.1.2Normative referencesThis ETS incorporates by dated and undated reference, provisions from other publications.

Page 9ETS 300 529: March 1995 (GSM 03.11 version 4.8.1)2Activation, deactivation, registration, erasure, interrogation and invocation2.1GeneralActivation, deactivation, registration, erasure, interrogation and invocation are defined independently from aparticular supplementary service. Whether they are applicable to a particular supplementary service or notis defined in the corresponding TS GSM 03.8x and 03.9x-series.The invocation of a supplementary service is executed as described in the corresponding stage 2description and always includes a MSC and a location register.When a MSC receives a request for either activation/deactivation or registration/erasure or aninterrogation, it invokes one of the following procedures.The MSC then can: -contact only the current VLR (e.g. interrogation of a call forwarding conditional supplementaryservice); -contact only the HLR (e.g. interrogation of the supplementary service call forwarding unconditional); -contact the HLR, after which the HLR updates the VLR (e.g. registration of a forwarding number fora conditional call forwarding supplementary service).Which of the above listed procedures is applied for a call independent supplementary service operation isdescribed in the corresponding TS GSM 03.8x and 03.9x-series.Successful activation, deactivation, registration and erasure change the service state at the HLR. Thesetransitions (if applicable to a particular service) are defined in the GSM 03.8x and 03.9x-series. Note thatthe HLR may also change the service state due to "HLR Induction" (see section 2.1.1).In connection with supplementary service operations the served subscriber or remote subscribers may getnotifications from the network.2.1.1Definition of "state vectors"In order to provide a tool to define service states the concept of a "state vector" is introduced. The statevector is used to represent the state of the service in terms of four variables:1)Provisioning State,possible values are "Provisioned" or "Not Provisioned";2)Registration State,possible values are "Registered", "Erased", or "Not Applicable";3)Activation State,possible values are "Not Active", "Active and Operative" or "Active and Quiescent";4)HLR Induction State,possible values are "Induced" or "Not Induced".The state vector represents the state of the service by using all four variables together. The state vector isrepresented using the notation:(Provisioning State, Registration State, Activation State, HLR Induction State)e.g.: (Provisioned, Registered, Not Active, Not Induced).SIST ETS 300 529 E1:2003



Page 10ETS 300 529: March 1995 (GSM 03.11 version 4.8.1)Note that the state vector is a logical (not a physical) representation of the service state. Note also thatthough some parts of the state vector are similar to elements of SS-Status the mapping between the statevector and SS-Status is not one to one. The use of state vectors is not intended to specify any particularimplementation internally in a node. There is a relationship specified between the state vector and parts ofthe transfer syntax. This relationship is not a direct one-to-one mapping.The following text specifies the semantics of each variable in the state vector.The three variables "Provisioning State", "Registration State" and "Activation State" are used to representthe state of the service according to the normal behaviour based on service provider and user actions.The "HLR Induction State" records whether or not the HLR has temporarily induced the service (e.g. if theVLR does not support CUG, the HLR may induce an outgoing barring service). The Provisioning State,Registration State and Activation State are not affected by HLR induction of a service.Provisioning State -has value "provisioned", if the subscriber has a subscription to the service; -has value "Not Provisioned" otherwise.Registration State -has value "Not Applicable", if registration is not applicable to the service; -has value "Registered", if registration is applicable, and there is registration data available; -has value "Erased" otherwise.Activation State -has value "Active and Operative", if the service is in a state where it can be invoked (and this is notdue to HLR induction); -has value "Active and Quiescent", if the service is in a state where it cannot be invoked, but where itwill automatically move to the "Active and Operative" state when conflicting conditions are removed; -has value "Not Active" otherwise.HLR Induction State -has the value "Induced" if the HLR has induced the service (e.g. if the VLR does not support CUG,the HLR may induce an outgoing barring service); -has the value "Not Induced" otherwise.For further information about how HLR induction applies to particular services refer to the GSM03.8x and 03.9x-series.2.1.2Handling of service states at the HLRValid states (represented by state vectors) are defined on a service-by-service basis in the GSM 03.8xand 03.9x-series. For each service the set of valid states represents the logical states that can exist in theHLR. The HLR contains the master copy of service state information.2.1.2.1Encoding of SS-StatusTo send service state information to the VLR or the MS, the HLR often uses the SS-Status parameter.This parameter contains four bits (referred to here as the "P bit", "R bit", "A bit" and "Q bit"). In a phase 2context the HLR shall encode the SS-Status using the mapping defined in this section from the servicestates to SS-Status.SIST ETS 300 529 E1:2003



Page 11ETS 300 529: March 1995 (GSM 03.11 version 4.8.1)If the HLR Induction State is "Not Induced" then: -If the Provisioning State is "Provisioned", then the P bit shall be 1, otherwise the P bit shall be 0. -If the Registration State is "Registered", the R bit shall be 1. If the Registration State is "NotRegistered" the R bit shall be 0. If the Registration State is "Not Applicable" the R bit shall be either0 or 1. -If the Activation State is "Active and Operative" the A bit shall be 1 and the Q bit shall be 0. If theActivation State is "Active and Quiescent" the A bit shall be 1 and the Q bit shall be 1. If theActivation State is "Not Active" the A bit shall be 0 and the Q bit shall be either 0 or 1.If the HLR Induction State is "Induced" then the P bit shall be 1, the R bit shall be 0 or 1, the A bit shall be1 and the Q bit shall be 0.HLR Induction State"Not Induced"P bitR bitA bitQ bitProvisioning State"Provisioned"1"Not Provisioned"0Registration State"Registered"1"Not Registered"0"Not Applicable"0/1Activation State"Active and Operative"10"Active and Quiescent"11"Not Active"00/1P bitR bitA bitQ bitHLR Induction State"Induced"10/110Table 2.1: Encoding of the P, R, A and Q bits in the SS-Status parameter2.1.2.2Invocation of services at the HLRIf the service can be invoked at the HLR (e.g. to bar an incoming call) then invocation is possible only if theActivation State is "Active and Operative". Note that the concept of HLR induction does not apply toservices invoked at the HLR as the HLR can invoke the effect of these services without needing to inducethem first.2.1.3Handling of SS-Status at the VLRThe VLR shall store sufficient information to support VLR based invocation, interrogation and notificationsfrom the VLR to the MS.The VLR shall not check the internal consistency of SS-S
