missing mobilityControlInfo IE from rrcConnectionReconfiguration at Handover #649

Closed catalin-nechifor closed 5 months ago

catalin-nechifor commented 5 months ago

Issue Description

I am running a test with 2 cells configured on the srs GNB and 1 UE. The GNB is configured to trigger handover from cell1 to cell2. When the measurement reports indicate that cell2 becomes more powerful than cell1, the GNB triggers rrcConnectionReconfiguration, as expected.

The issue is that this reconfiguration does not contain mobilityControlInfo IE which tells the UE where to handover to.

Expected Behavior

I expected that mobilityControlInfo IE is sent by the GNB when instructing the UE to perform handover missing IE

Hi @catalin-nechifor, please note that the srsRAN_Project is a 5G RAN solution, while the mobilityControlInfo IE is a LTE parameter, that is not present in 5G anymore. The information you are looking for is probably available in the radioBearerConfig or measConfig.

Thank you for the clarification Fabian!
