<strong>GSM</strong> <strong>09.02</strong> <strong>Version</strong> <strong>5.3.0</strong>: August 1996<br />

16.2.3.6 SDL Diagrams<br />

The SDL diagrams on the following pages describe the user process in MSC-B for the procedures<br />

described in this subclause.<br />

The services used are defined in subclause 6.4.<br />

NOTE 1: The message primitives HO_CA_MESSAGE in the SDL-diagrams are used to show the<br />

internal co-ordination between the MAP application and the Handover Control<br />

Application. For a detailed description of the co-ordination between the applications for<br />

the handover procedure, see TS <strong>GSM</strong> 03.09.<br />

NOTE 2: The order in the SDL diagrams to allocate first the handover number and then the radio<br />

resources is not binding.
