DETAILED DESCRIPTION To address the above-discussed deficiencies of the prior art, it is a primary objective of the present invention to provide, for use in a wireless network base station, the base station capable of communicating in at least one overhead channel and a plurality of traffic channels with a plurality of mobile stations by means of a plurality of channel elements, an apparatus for recovering from an overhead channel failure comprising: 1) a failure detection circuit capable of detecting a failed overhead channel and generating a failure notification; and 2) a channel allocator capable of receiving the failure notification and, in response thereto, a) identifying a failed one of the plurality of channel elements responsible for the failed overhead channel and a first signal processing device associated with the failed overhead channel element; and b) selecting an available traffic channel element to replace the failed channel element, wherein the available traffic channel element is located on a second signal processing device that is processing a least number of overhead channels thereon.
According to one embodiment of the present invention, the second signal processing device and the first signal processing device comprise distinct digital signal processors.
According to another.
embodiment of the present invention, the second signal processing device and the first signal processing device comprise distinct digital signal processors disposed on separate channel card circuits.
According to still another embodiment of the present invention, the least number of overhead channels is zero.
According to yet another embodiment of the present invention, the available traffic channel element is an idle traffic channel element.
According to a further embodiment of the present invention, the second signal processing device and the first signal processing device are disposed on separate channel cards.
According to a still further embodiment of the present invention, the apparatus further comprises a database associated with the channel allocator, wherein the database stores physical device location parameters associated with the plurality of channel elements
