Patent number: 5970416
Abstract: The following describes an apparatus for and method of providing and supporting distributed call handling over a plurality of network nodes (401, 403, 405, 407, 409, 411, 413) in a communication system, wherein the network nodes (401, 403, 405, 407, 409, 411, 413) are found in each device with the system, rather than only in the repeaters (101, 103, 105, 107, 109), the site controller (111), or the zone controller (ZC) for the system. The call establishment process is provided as elements (301, 303, 305, 307, 309, 311, 313) of a state machine. Each of the elements (301, 303, 305, 307, 309, 311, 313) is distributed over one or more of the plurality of network nodes (401, 403, 405, 407, 409, 411, 413). If one of the network nodes becomes unavailable, the element(s) supported by the now unavailable network node is reassigned (705, 809), as necessary.
