Abstract

A communications system infrastructure (100), such as an integrated services radio system, is provided with a hold processor (126). The hold processor is operably coupled to at least one base station controller (114). If a mobile subscriber unit (102) is actively engaged in a first communication service, such as a telephone interconnect call, and desires to use a second communication service, such as making or responding to a dispatch call, the mobile subscriber unit request the first service to be held. The base station controller then switches the first service to the hold server, which in turn generates an identifier for transmittal to the mobile subscriber unit for storage and call retrieval at a later time.

Claims

1. A communications system for providing multiple services and hold capability of at least one service, the communications system having a mobile switching center and a dispatch control processor for communicating with a plurality of mobile subscriber units, the mobile switching center providing telephone interconnect call capability between mobile subscriber units and a public switched telephone network, the dispatch control processor providing dispatch call capability between the mobile subscriber units, the communication system comprising:

a base site controller operably coupled to the mobile switching center

a transceiver site operably coupled to the base site controller and to the dispatch control processor, and having a radio transceiver for transmitting and receiving radio signals to and from the mobile subscriber units;

a hold processor operably coupled to the base site controller and the mobile switching center, for receiving and holding a telephone interconnect call in progress by at least one of the mobile subscriber units.

2. A communications system as defined by claim 1, wherein the hold processor comprises a means for generating and associating an identifier with the telephone interconnect.

3. A communications system as defined by claim 1, wherein the hold processor is operably coupled to a plurality of base site controllers.

4. A communications system as defined by claim 1, further comprising a transcoder disposed between the base site controller and the mobile switching center.

5. A communications system as defined by claim 1, further comprising a database containing information about the mobile stations, the database being coupled to both the dispatch control processor and the mobile switching center.

6. A communications system for providing multiple services and hold capability of at least one service, the communications system having a mobile switching center and a dispatch control processor for communicating with a plurality of mobile subscriber units, the mobile switching center providing telephone interconnect call capability between the mobile subscriber units and a public switched telephone network, the dispatch control processor providing dispatch call capability between the mobile subscriber units, the communication system comprising:

a plurality of base site controllers, each operably coupled to the mobile switching center;

a plurality of transceiver sites, each operably coupled to one of the base site controllers and the dispatch control processor for sending and receiving radio signals to and from the mobile subscriber units; and

a plurality of hold nodes, each hold node operably coupled with one of the base site controllers.

7. A communications system as defined by claim 6, further comprising a transcoder disposed between the base site controller and the mobile switching center.

8. A communications system as defined by claim 6, further comprising a database containing information about the mobile subscriber units, the database being coupled to both the dispatch control processor and the mobile switching center.

9. A communications system as defined by claim 6, wherein the dispatch control processor comprises a dispatch applications processor and a metropolitan packet switch.
