GSM 09.02 Version 5.3.0: August 1996
Annex C (informative): Formal protocol incompatibilities between versions 1
and 2 of MAP
C.1 Introduction
Annex C is not normative; it presents for information those parts of the MAP version 2 protocol which are
not backward compatible with (i.e. a true superset of) the MAP version 1 protocol. For each incompatibility
there is a commentary on the impact on the interworking of MAP version 1 and MAP version 2 entities.
SMG have decided that the MAP specification should include the operations and procedures used on the B
interface (MSC/VLR) only for modelling purposes; the B interface cannot be implemented as an open
interface. Hence any incompatibilities which affect operations used only on the B interface have no impact
on the interworking of MAP version 1 and MAP version 2 entities.
C.2 Deletion of operations and errors
This subclause lists the operations and errors which have been completely removed from the MAP
protocol.
C.2.1 Deletion of operation DeregisterMobileSubscriber
Although it is defined in the protocol in the MAP version 1 specification, this operation is not used
(see subclause 1.2 of the latest phase 1 version of TS GSM 09.02).
C.2.2 Deletion of operation RegisterChargingInfo
There is no known implementation of MAP version 1 which supports this operation. The deletion has been
approved by SMG.
C.2.3 Deletion of operation ForwardSS-Notification
There is no known implementation of MAP version 1 which supports this operation. The deletion has been
approved by SMG.
C.2.4 Deletion of operations used only on the B-interface
The following operations (listed in alphabetical order) are not defined in the MAP version 2 protocol,
because they are used only on the B-interface:
AllocateHandoverNumber; AttachIMSI; Authenticate; CompleteCall; DetachIMSI; ForwardNewTMSI;
InvokeSS; Page; ProcessAccessRequest; ProvideIMSI; SearchForMobileSubscriber;
SendHandoverReport; SendInfoForIncomingCall; SendInfoForOutgoingCall; SetCipheringMode;
UpdateLocationArea.
C.2.5 Deletion of error InsufficientBearerCapabilities
This error is defined in the MAP version 1 protocol, but it is not specified for use with any operation.
C.3 Deletion of errors for operations
This subclause lists the cases where an error which is specified for use with an operation in the MAP
version 1 specification is not specified for use with the same operation in the MAP version 2 specification.
C.3.1 Error NegativePW-Check for operation RegisterSS
Password checking is not used for the supplementary services to which registration applies.
