1. A method of enabling multi-connectivity in a wireless network for improving quality of service for a user equipment (UE), the method comprising:
predicting, by a network device, at least one of a radio link failure (RLF), a call drop, or a jitter based on a plurality of key performance indicators (KPIs) associated with the UE and the wireless network;
determining, by the network device, whether the UE is in one of a dual connectivity (DC) mode and a carrier aggregation (CA) mode;
performing, by the network device, one of:
adding a new secondary gNodeB (gNB) in response to determining that the UE is not in both the DC mode and the CA mode and converting a new gNB to a master gNB,
converting an existing secondary gNB to a master gNB with one of an existing master cell group (MCG) gNB and another gNB as a secondary gNB, in response to determining that the UE is in the DC mode, and
converting an existing secondary cell to a primary cell in response to determining that UE is in the CA mode; and
enabling, by the network device, the multi-connectivity in the wireless network to avoid at least one of the RLF, the call drop, or the jitter in one of the CA mode and the DC mode.
