MAC PROCESSING METHOD USING STATISTICS CHARACTERISTICS OF VOICE TRAFFIC |
摘要 |
PURPOSE: A MAC(Medium Access Control) processing method using statistics characteristics of a voice traffic is provided to effectively detect an activation state of a voice session and enhance efficiency of a system resource. CONSTITUTION: After a deletion/insertion procedure of a record by lists is completed by a voice state monitoring unit(401), a polling controller updates a lapse time field value of the first record of an inactive list of the voice state monitoring unit to a value obtained by adding a frame duration time(402). The lapse time field value is compared with a state transition probability value(403). If the lapse time field value is greater than the state transition probability value, the record is inserted in a unicast polling list and a corresponding record is deleted from the inactive list(404). If the lapse time field value is smaller than the state transition probability value, it is checked whether there is a next record(405). Starting from the first of the unicast polling list, a lapse count field value of a record is increased by 1(406), and the value is modular-calculated with a packet cycle, and then, a result value is compared with 0(407). If the result value is not 0, it is checked whether a next record exists in the unicast polling list(409).
