Parameter Name |
Maximum Value of N3103 |
|---|---|
Description |
This parameter specifies the maximum value of the N3103. Upon receiving the last RLC data block when the uplink transmission is complete, the network sends the MS a Packet Uplink Ack/Nack message with FAI=1 and initiates the N3103. If the network does not receive a packet control acknowledgment message within scheduled time, the N3103 increases by one and the network resends the Packet Uplink Ack/Nack message. When this counter overflows, the network initiates the T3169. When this timer expires, the current TBF abnormally releases. |

Configuration Policy |
If this parameter is set to a lower value, the abnormal uplink TBF release increases caused by the overflow of the N3103. If this parameter is set to a higher value, the release time of the uplink TBF delays due to no response of the MS caused by the bad Um interface quality, thus occupying the link resources of system. 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. |
