Technical Description on Flexible A-bis

Flex Abis Timeslot Allocation:

In traditional mode, there is a one-to-one correspondence between the Um interface resources and the Abis interface transmission resources. Even if the Um interface resources are idle, the fixed Abis interface transmission resources are also occupied. After Flex Abis is enabled in the BSC, the Abis interface transmission resources use the resource pool mode. The associated Abis interface transmission resources are allocated on demand only when the Um interface resources

are occupied. This substitutes the traditional fixed resource allocation mode and improves the utilization of the Abis interface transmission resources. Except that the monitoring timeslot

(TS0), RSL, and OML still use the fixed allocation mode of the Abis interface transmission resources, other Abis interface transmission resources fall into the resource pool, as shown in

Figure.
