1. One kind through the access of controlling new calling be maintained in require in the cellular communications network level other voice quality method, said method comprises the following steps:

  • A Serving cell or the uplink voice quality measurements and the downlink voice quality measurements of at least one peripheral cell through measuring in the said cellular communications network to confirm the speech quality measurement result for said Serving cell;

    AndSpeech quality measurement result according to said Serving cell and at least one peripheral cell uses cell-level method, sub cell level method or synthesis to determine whether to allow new the calling to insert then, requires other voice quality of level in the said Serving cell thereby be maintained in,Wherein use said cell-level method determine whether to allow new call out to insert comprise;

    the said speech quality measurement result who surpasses a minimum threshold or said at least one peripheral cell except the said speech quality measurement result of said Serving cell surpasses the situation of a minimum threshold;

    Just allow the new step that inserts of calling outWherein using said sub cell level method to determine whether to allow new calling to insert comprises;

    except the speech quality measurement result in the subregion of said at least one peripheral cell surpasses a minimum threshold, perhaps the speech quality measurement result in the subregion of said Serving cell surpasses the situation of a minimum threshold;

    Just allow new the calling to insert, andWherein use said synthesis determine whether to allow new call out to insert comprise;

    a minimum threshold and the speech quality measurement result in the subregion of said at least one peripheral cell surpass a minimum threshold, or the speech quality measurement result of said Serving cell surpasses a minimum threshold and the speech quality measurement result in the subregion of said Serving cell surpasses the situation of a minimum threshold, just allows new the calling to insert except the speech quality measurement result of said at least one peripheral cell surpasses.
