Parameter Name |
Release Delay of Non-extended Uplink TBF(ms) |
|---|---|
Description |
This parameter specifies the release delay of the non-extended uplink TBF. Upon receiving the last uplink RLC data block (CountValue=0), the network sends the MS a Packet Uplink Ack/Nack message with FAI=1 to notify the MS of releasing this uplink TBF. To establish the downlink TBF on the unreleased uplink TBF, the network will notify the MS of releasing this uplink TBF for a period of delay after this parameter is set. After the downlink TBF establishes successfully or after the delay time exceeds the setting time of non-extended uplink TBF, this uplink TBF will automatically release. The value 0 specifies that the release delay of the non-extended uplink TBF is disabled. |

If this parameter is set to a higher value, this can increase the probability of establishing the downlink TBF on the PACCH, thus greatly reducing the downlink TBF establishment time; however, if the MS needs to send new uplink data, because the BSC6000 does not support the uplink establishment function on the uplink at present, the reserved uplink TBF must be released and a new TBF must be established to transmit the new data. Therefore, the overall transmission performance decreases. If this parameter is set to a lower value, this can decrease the probability of establishing the downlink TBF on the PACCH. The downlink TBF must establish on the CCCH, thus increasing the establishment time. |
