In situations where the PCU is co-located to the BSC, the IMMEDIATE ASSIGNMENT for downlink TBFs must be sent via RSL and the BSC also must instruct the BTS to transmit the IMMEDIATE ASSIGNMENT via PCH instead of AGCH. Eventually the BSC must sent a confirmation message (follow-up patch) where the TLLI is used as an identifer. This new method will eventually replace the previous method that uses the MAC block as an identifier. To remain compatible with older versions of osmo-bsc, we will keep the old method until osmo-bts is migrated as well. This patch also requires new features to be added to the PCU socket interface the version number of the protocol is incremented from 0x0a to 0x0b. Version 0x0a will remain compatible and use the old method, while version 0x0b will use the new method introduced with this patch.
