Combined handover of the circuit -switched (CS) and packet-switched (PS) resources.

(57)    Abstract

The problem of synchronization of the handover of the CS and PS resources to the .same target cell during DTM handover is solved without affecting the

performance of the CS handover, The mechanism of synchronizing the handover of the PS

and CS resources is supported by the following functions: (I) resource indications on the CS and PS handover signaling to indicate target cell

network nodes that the CS and PS handover is ongoing at the same lime for the same MS: (2) allocated resources | indications on the CS and PS


signaling lo indicate to the source cell nodes that there are resources available
