GSM 09.02 Version 5.3.0: August 1996
The Call Transfer, User to User Signalling, Conference Calling and Mobile Access Hunting supplementary
services are not specified for GSM Phase 1 or GSM Phase 2, so data for these services should not be
transferred in a dialogue involving a MAP version 1 entity. These cases will therefore not be discussed
further.
The type SS-SubscriptionOption is used for a component of SS-Data and for the parameter of the error
SS-SubscriptionViolation.
C.4.16 SubscriberData
The type SubscriberData is a sequence of which one component is of type SS-InfoList. Components of
SubscriberData are used as a component of the parameter of the operation InsertSubscriberData; the
type is also used for a component of the type SentParameter.
C.5 Changes to parameters of errors
This subclause lists in alphabetical order the errors whose parameters have changed.
C.5.1 CUG-Reject
The error CUG-Reject has an optional parameter of type CUG-RejectCause. The error CUG-Reject is
used for the operation SendRoutingInfo.
C.5.2 SS-SubscriptionViolation
The error SS-SubscriptionViolation has an optional parameter of type SS-SubscriptionOption. The error
SS-SubscriptionViolation is used for the operations ActivateSS, DeactivateSS, EraseSS and RegisterSS.
C.6 Changes to parameters of operations
This subclause lists in alphabetical order the operations whose parameters have changed, and gives a
commentary on the effect of the changes on each operation.
C.6.1 InsertSubscriberData
The parameter of the operation InsertSubscriberData is a sequence of which one component is a
sequence of components of SubscriberData. The components of SubscriberData which are affected by the
changes listed in subclause C.4 are cug-Info and ss-SubscriptionOption.
The CUG supplementary service is not supported by MAP version 1; CUG-Info should therefore not be
used as a component of SubscriberData in a dialogue involving a MAP version 1 entity.
The replacement of the perCallBasis (type BOOLEAN) subscription option by the cliRestrictionOption (type
ENUMERATED) for the CLIR supplementary service means that full support for the CLIR supplementary
service is not possible if either entity involved can support only MAP version 1.
C.6.2 RegisterSS
The forwardedToNumber component of the parameter of the operation RegisterSS had a maximum length
of 10 octets in MAP version 1, as it was of the type ISDN-AddressString. In MAP version 2 the maximum
length is 20 octets, as the type is AddressString. The maximum length (9 octets) of the
ISDN-AddressString type in MAP version 2 may not be adequate to hold the forwardedToNumber, which is
not necessarily an E.164 number; the user may enter the number using the digits for international access
rather than the "+" key.
