Method of improving the performance between one mobile station and a base station by selective setting of the retransmission time-out values

摘要

The present invention relates to a method of selective setting of retransmission time-out values in a mobile, radio communication system. A mobile station (MS1) communicates with a base station system (BSS). The mobile station (MS1) can be in any cell in a public land mobile network (PLMN). The base station system (BSS) communicates with a serving GPRS support node (SGSN). A parameter T200D is representing retransmission time-out in downlink direction and a parameter T200U is representing retransmission time-out in uplink direction, between the mobile station (MS1) and the serving GPRS support node (SGSN). Both parameters T200D and T200U replace the T200 parameter. If the logical link control (LLC) connection is in asynchronous balanced mode (ABM) then at chosen time intervals the T200D and T200U are measured and if required negotiated.
