Parameter Name |
Maximum Value of N3101 |
|---|---|
Description |
This parameter specifies the maximum value of N3101. In uplink dynamic assignment mode, the multiple MSs can share one uplink channel if the downlink data blocks carry the USF value. After the network starts to assign a USF value to the uplink TBF (uplink TBF is established), the N3101 is initiated. The network reserves the RLC uplink blocks mapping to each USF for the uplink data sent from the MS. If the network receives valid uplink data blocks from the MS, the network resets the N3101; otherwise, the N3101 increases by one. When this counter overflows, the current uplink TBF abnormally releases. |

If this parameter is set to a lower value, the tolerance of the network to uplink errors decreases and the probability of the frequent TBF release increases. If this parameter is set to a higher value, the abnormal TBF may occur (such as the MS has not received the message of current cell in the network caused by the MS activities, the network still assigns the uplink resources to the MS), the network cannot release this TBF, thus wasting the network resources. Based on the actual condition of existing network (for example, the N3101 overflow caused by the bad Um interface quality, the unstable transmission link quality, and the MS activities), you should properly adjust this parameter to ensure the uplink TBF does not abnormally release due to the frequent overflow of the N3101. |
