Inactive Period of Extended Uplink TBF(ms)

Inactive Period of Extended Uplink TBF(ms)

This parameter specifies the inactive period of the extended uplink TBF.

Upon receiving the last uplink RLC data blocks (CountValue=0) from the MS that supports the extended uplink TBF function, the network does not release this uplink TBF immediately but set it to the inactive mode. To transmit the uplink RLC data blocks during inactive period, the MS can use this TBF that automatically becomes active instead of establishing a new uplink TBF. When the inactive period expires, if no uplink RLC data block needs to be transmitted, the network sends the MS a Packet Uplink Ac message with FAI=1 to notify the MS of releasing the uplink TBF. In addition, when an uplink TBF is inactive, a downlink TBF can still establish on this uplink TBF.

The extended uplink TBF function can greatly improve the network KPIs, especially for the discontinuous uplink transmission (such as interactive transmission and Ping) services.

The value 0 specifies that the extended uplink TBF function is disabled (Also deactivate this function on the BSC side).

If this parameter is set to a higher value, the release delay of the uplink TBF increases, thus wasting the uplink resources.

If this parameter is set to a lower value, the uplink TBF frequently releases and establishes, thus increasing the delay for the delay tests of the Attach and Ping services. The most optimized value should be a little greater than the interval between two discontinuous uplink transmissions.

This function requires the support of the MS. Therefore, there are certain limitations for this function usage. Such as the existing network has a high requirement on the Ping services.
