name: HO
full_form: Handover
context: In LTE, Mobility Robustness Optimization (MRO) aims at detecting and enabling correction of following problems, which will deteriorate user experience and waste network resources: - Connection failure due to intra-LTE or inter-RAT mobility; - Unnecessary HO to another RAT (too early IRAT HO with no radio link failure); - Inter-RAT ping-pong. For connection failure due to intra-LTE or inter-RAT mobility, three kinds of failures were identified: too late HO, too early HO and HO to a wrong cell. The detection of the events is enabled by the RLF Indication and HO Report procedures. By analysing the report from UE and network side information, HO related parameters could be adjusted to resolve the detected problems. For unnecessary HO to another RAT, the RAN node in the other RAT, may instruct the UE to continue to evaluate the received measurement reports with the coverage/quality condition received during the inter-RAT HO preparation phase and decide if an inter-RAT unnecessary HO report
description: Handover (HO) is a procedure in LTE networks that involves the transfer of a user's connection from one cell to another, either within the same Radio Access Technology (RAT) or between different RATs. The HO procedure is crucial for maintaining seamless connectivity and preventing connection failures due to mobility.
explanation: The abbreviation 'HO' is classified as a Procedure because it describes an action taken by the network to transfer a user's connection between cells. This action is essential for maintaining connectivity and preventing failures, which are characteristics of procedures in telecommunications.
