Abstract
A method and apparatus for controlling calls in in a distributed processing communications switching system. A call is assigned to any one of a plurality of call control processors. The assigned processor thereafter directs the establishment of communications connections for that call. In the exemplary embodiment, the control of a cellular mobile communications switching system, a high speed data ring is used to communicate among a switching network, the call control processors, and call assignment processors of the system. Advantageously, each of the call control processors can be fully utilized since each may be flexibly assigned to any set of communications ports or terminals. New calls to a terminal which is already on an existing call are assigned to the call control processor assigned to control the existing call. Advantageously, call data for all calls to that terminal are therefore under the control of a single processor.
