GSM 09.02 - Version 5.3.0 - Digital cellular telecommunications - ETSI

C.7.4 GetPassword
Page 745
GSM 09.02 Version 5.3.0: August 1996
The result of the operation GetPassword is of type Password. In MAP version 1 this was a choice
between a printable string of length 4 to 8 octets or a numeric string of length 4 octets. It is now a numeric
string of length 4 octets. The printable string option was never used in MAP version 1, as indicated by a
comment in the ASN.1 in the latest phase 1 version of TS GSM 09.02.
C.7.5 InterrogateSS
The result of the InterrogateSS operation is a CHOICE; one of the components of the CHOICE is a list of
basic services to which the supplementary service applies, which is used for the Call Barring
supplementary service. In MAP version 1 this list can in principle have up to 70 members, the number of
individual basic services. However Call Barring can apply to only 13 basic service groups. In MAP version 2
the length of the list of basic service codes which can be returned in the result of the InterrogateSS
operation is reduced to 13 to reflect this.
C.7.6 RegisterSS
The result of the operation RegisterSS is of type SS-Info. Two data types used for components of SS-Info
have suffered incompatible changes: CUG-Info and SS-SubscriptionOption.
The RegisterSS operation does not apply to the CUG supplementary service, so the cug-Info component
of SS-Info should never be present in the result of the operation RegisterSS.
The RegisterSS operation does not apply to the CLIP, CLIR or COLP supplementary services, for which
the type SS-SubscriptionOption is used, so the ss-SubscriptionOption component of SS-Info should never
be present in the result of the operation RegisterSS.
C.7.7 SendParameters
The result of the operation SendParameters is of type SentParameterList, which is a sequence of
components of type SentParameter. The maximum number of components in the sequence has been
reduced from 10 to 6. MAP version 1 could in principle send 10 sets of CUG-Information, but the
supplementary service Closed User Group is not defined for GSM Phase 1, and the MAP version 1
signalling protocol will not support Closed User Group as defined for GSM Phase 2, so a MAP version 1
entity should never request parameters for CUG. The maximum number of sent parameters therefore
consists of an IMSI and 5 AuthenticationSets - a total of 6.
The type SentParameter is a choice of which one component is of type 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.7.8 SendRoutingInfoForSM
The result of the operation SendRoutingInfoForSM is a sequence of which one component was a choice
between location information (optionally with an associated LMSI) and forwarding data; the choice of
forwarding data has been removed. Call Forwarding does not apply to the short message service.
