Method for selecting traffic channel of mobile telecommunication base station

摘要

A method for selecting traffic channels of a mobile telecommunication base station is disclosed. Normal traffic channel elements and busy traffic channel elements are calculated and compared with each other, and a judgment is made as to whether there is a usable traffic channel element. Busy traffic channel elements of respective shelves are compared with each other to select a shelf having smallest busy traffic channel elements. Busy traffic channel elements of the selected shelf are compared with normal traffic channel elements of the same shelf, to judge as to whether there is a usable traffic channel element. A termination condition is incremented by 1 upon finding a usable traffic channel element, and a judgment is made as to whether the selected shelf index is smaller than a last shelf index. The channel card index is updated, and the self index is incremented by 1 upon finding the selected shelf index to be smaller than a last, and confirming the sequential selected shelf index. A traffic channel element is selected upon finding that the selected traffic channel element is in an idle state, and that the selected shelf corresponds to the shelf including the relevant traffic channel element.
