C.4 Changes to definitions of data types<br />

This subclause lists in alphabetical order those data types whose definitions have been directly or indirectly<br />

changed. For constructed data types, only the components which have been changed are mentioned. The<br />

commentary on the end effect of each change is given in subclauses C.6 (parameters of operations), C.7<br />

(results of operations) or C.8 (errors of operations).<br />

C.4.1 CUG-Feature<br />

The type CUG-Feature was a sequence of four components; these have been deleted and replaced by<br />

three new components. It is used for the components of the type CUG-FeatureList.<br />

C.4.2 CUG-FeatureList<br />

The type CUG-FeatureList is a sequence of components of type CUG-Feature. It is used for a component<br />

of the type CUG-Info.<br />

C.4.3 CUG-Info<br />

The type CUG-Info is a sequence. One component of the sequence has been replaced by a component of<br />

a new type; the other component was a choice between a cug-Feature and a cug-FeatureList, and is now<br />

an optional cug-FeatureList. The type CUG-Info is used for a component of the type SS-Info.<br />

C.4.4 CUG-RejectCause<br />

The range of permitted values of the enumerated type CUG-RejectCause has been extended. The type is<br />

used for the parameter of the error CUG-Reject.<br />

C.4.5 IMSI<br />

The lower limit of the length of an IMSI has been increased from 2 octets to 3 octets. It is not possible to<br />

code a minimum length IMSI (MCC+MNC+MSIN) in 2 octets, so the theoretical lower limit of 2 octets<br />

should never be used by a MAP version 1 entity to send an IMSI; if it is, a MAP version 2 entity will treat it<br />

as a protocol error. Since this change has no practical impact it is not discussed further.<br />

C.4.6 ISDN-AddressString<br />

The upper limit of the length of an ISDN-AddressString has been reduced from 10 octets to 9 octets. The<br />

maximum length of an E.164 number is 15 digits; this can be encoded as a TBCD-string in 8 octets, plus a<br />

further octet to hold the type of number and number plan indicator. The cases where the<br />

ISDN-AddressString type was used in MAP version 1 to carry anything other than an E.164 number are<br />

described in subclause C.6; the other cases are not discussed further.
