ASSUMPTIONS FOR DEFINITION OF REGISTRATION The registration of a mobile station occurs when the HLR sets its location

33、 pointer for the mobile station to point to the VLR. The mobile station is considered to be registered in the VLR as long as this pointer is directed from the HLR to the VLR. Registration of the mobile station in the VLR ceases when the HLR resets its location pointer for the mobile station or direc

34、ts the pointer elsewhere. VLR registration of a mobile station ceases when a RegistrationCancellation is received for the mobile station or after a CSSInactive INVOKE with a DeregistrationType parameter is sent to the HLR. ASSUMPTIONS FOR REGISTRATION STATES * A mobile station which is registered in

35、 a VLR remains registered until one of the following events occurs: 1) the HLR sends a RegistrationCancellation INVOKE to the VLR. 2) the VLR sends a CSSInactive INVOKE with a DeregistrationType parameter to the HLR. 3) the HLR receives a RoutingRequest RETURN ERROR indicating 43 44 UnrecognizedMI”

The action of registration means that the HLR se

38、ts its location pointer for the mobile station to be directed to the VLR. The VLR has control over its internal memory resources. The VLR can autonomously remove a service profile without informing the HLR if and only if the VLR treats an incoming call in a manner that is not dependent upon the serv

39、ice profile. If the mobile station requests service, the Visited System must obtain the service profile if it is not stored in the VLR. ASSUMPTIONS FOR HLR MAINTENANCE OF PROFILE RECORDS IN THE VLR Introduction Once the HLR has delivered a profile to a VLR for a registered roamer, the HLR is require

40、d to update the profile as necessary for the duration of registration. The HLR shall send the entire service profile in response to a RegistrationNotification or a QualificationRequest INVOKE if the received QualificationInformationCode parameter has the value “Profile only” or “Validation and Profi

43、 Problem a b C d e The parameters to be returned in the RegistrationNotification and QualificationRequest RETURN RESULTS for Validation Only and Profile Only QualificationInformationCode parameter values were not defined. For all QualificationInformationCode parameter values, AuthorizationDenied is

44、returned without other optional parameters for an unauthorized CSS. Validation Only requires the return of AuthonzationPeriod parameter for an authorized CSS. Profile Only requires the return of OriginationIndicator, TerminationRestrictionCode and CallingFeaturesIndicator parameters. The Digits (des

45、tination) parameter must be included if so indicated by the Originationindicator. The Digits (carrier) parameter may optionally be included for any CSS. Validation and Profile uses elements of b and c, as required. In response to a request for qualification information, the HLR may respond with more

46、 qualification information than requested by the QualificationInformationCode parameter received from the VLR. 3 Decision Points EIA TSB41 94 m 3234b00 0557038 959 TINEIA TSB 41 2. Validation and Profile Expiration Problem a b Validation and Profile expiration periods were not explicitly defined. Th

47、e expiration of validation is controlled by the interval specified in the AuthorizationPeriod parameter. Per Call AuthorizationPenod indicates that there is no validation period, i.e., the VLR must retrieve validation information from the HLR after MS system access but before providing service. Afte

48、r expiration of the Authorization Period, the serving VLR must retrieve validation information from the HLR before providing service (except for call delivery which has an implicit single call authorization). The serving VLR shall reieve validation information from the HLR with a RegistrationNotific

49、ation or QualificationRequest. The HLR shall provide the CSS authorization changes with a QualificationDirective. A profile remains valid in the VLR until changed with a ServiceProfileDirective or QualificationDirective, or until revoked with a RegistrationCancellation or a CSSInactive with a DeregistrationType parameter. The VLR may discard the profile or validation information at any time. However, registration remains in effect. c d e 3. Repetitive Registration Prevention Problem a No mechanism is defined to prevent r
