Description |
This parameter specifies the length of timer T3150. For details, see GSM Rec. 08.58 and 04.08. When the BTS sends physical information to the MS, the BTS starts the timer T3105.If the timer T3105 expires before BTS receives the SAMB frame from MS, BTS resends physical information to MS and restarts the timer T3105. The maximum times for resending physical information is Ny1. |

The physical information is sent over the FACCH. Four TDMA frames are sent each time at the interval of 18 ms. If the value of T3105 is smaller than or equal to 18 ms, the BTS needs to retransmit the physical information to the MS when the timer T3105 expires for the first time.If the transmission of the physical information over the FACCH is not complete, the expiration is invalid because the time is shorter than an FACCH period.Considering the previous factors, 20 ms is the reasonable minimum value for this parameter. At present, the default value of this parameter is 70 ms. |
