ABSTRACT:
A mobile services switching center (MSC) for a digital cellular communication network is disclosed. The MSC comprises functionality for performing switching functions necessary to cover mobile stations (MSs) receiving services from the MSC and for monitoring the mobility of the MSs covered by the MSC. The MSC schedules unstructured supplementary service data dialogues to at least one virtual transaction channel between the MSC and a MS. Since several unstructured supplementary service data dialogues may be processed in parallel, unstructured supplementary service data requests will no longer be rejected during another unstructured supplementary service data dialogue, thus providing a very efficient approach with respect to throughput and reject ratio for unstructured supplementary service data dialogues.
