First Claim
Patent Images
1. A radio communication system for providing communication services to a plurality of mobile stations, comprising:
- an interconnect subsystem for providing interconnect services that allow the plurality of mobile stations to communicate by way of a public switched telephone network (PSTN);
a dispatch subsystem for providing dispatch services to the plurality of mobile stations; and
a call processor, operatively coupled to the interconnect subsystem and the dispatch subsystem, for integrating the interconnect services and the dispatch services provided to the plurality of mobile stations, wherein integrating comprises providing at least one response directed to a source mobile radio communication unit in a first service mode that includes an indication that a target mobile radio communication unit is engaged in a call in a second service mode, wherein the first service mode and the second service mode are supported by different subsystems from the group comprising the interconnect subsystem and the dispatch subsystem.

Abstract
A radio communication system (10) that includes a method and call processor (18) for integrating multiple services. The call processor (18) provides a transparent interface between various service subsystems (12-16) to allow inter-service call waiting notification and to improve overall system reliability and performance. A local home location register (HLR) (21) stores mobile subscriber unit status information, permitting the call processor (18) to perform call notification and route calls more efficiently.
