NOTE 1: The message primitive names used in the SDL diagrams and message flows in the present document do not represent the actual messages specified in the GSM or 3GPP stage 3 technical specifications. The primitive names are only intended to be indicative of their use in the present document.

SDL Annotation.

The following conventions and abbreviations have been used in the SDLs. Text included in ‘[]’ is used to indicate either, the BSSMAP message (as defined in 3GPP TS 49.008 [7]) included in the message, or the transport of a Handover Number.

When traversing the following SDLs it may be possible that resources appear to be released repeatedly, however these operations are only executed once on their first occurrence. Furthermore it maybe that certain messages cannot, in practice, be received in particular states, after specific events have taken place. In general both of the above cases are obvious. This approach has been adopted (in line with other GSM Technical Specifications) in order to reduce the complexity of the SDLs and improve clarity, without reducing the quality of the functional description.

The following abbreviations have been used in the SDLs:

A-HO-REQUEST A-HANDOVER-REQUEST

A-HO-REQUEST-ACK A-HANDOVER-REQUEST-ACK.

A-HO-COMPLETE A-HANDOVER-COMPLETE

A-HO-DETECT A-HANDOVER-DETECT

A-HO-PERFORMED A-HANDOVER-PERFORMED

A-ASG-REQUEST A-ASSIGNMENT-REQUEST

A-ASG-COMPLETE A-ASSIGNMENT-COMPLETE

A-ASG-FAILURE A-ASSIGNMENT-FAILURE

MAP-PAS req MAP-PROCESS-ACCESS-SIGNALLING req.

MAP-FAS req MAP-FORWARD-ACCESS-SIGNALLING req.

IU-RLC-REQUEST IU-RELOCATION-REQUEST

IU-RLC-REQUEST-ACK IU-RELOCATION-REQUEST-ACK

IU-RLC-COMPLETE IU-RELOCATION-COMPLETE

IU-RLC-DETECT IU-RELOCATION-DETECT

IU-IREL-REQUEST IU-IU-RELEASE-REQUEST

IU-RREL-REQUEST IU-RAB-RELEASE-REQUEST

IU-RASG-REQUEST IU-RAB-ASSIGNMENT-REQUEST

IU-RASG-RESPONSE IU-RAB-ASSIGNMENT-RESPONSE

NOTE 2: The SDL diagrams have been checked for consistency with the allocation of the A interface circuits by the BSC. The conclusion was that SDLs are expressed in general terms, and offer a sufficient latitude of interpretation to be consistent with the allocation of A interface circuits by the BSC.
