A method of handling an ongoing call performed by a UE in a wireless network is provided. The method includes initiating a voice over long term evolution call in a 4G network, detecting that a 5G network entity has configured an inter radio access technology measurement indicating a change from the 4G network to a 5G network based on identification of the 5G network, determining whether at least one of the UE or the 5G network does not support a voice over new radio (VoNR) call with a 5G cell, in response to determining that the at least one of the UE or the 5G network does not support the VoNR call, delaying sending a measurement report until the VOLTE call is completed, and in response to determining that both the UE and the 5G network support the VoNR call, sending the measurement report immediately for the 5G cell.

Method and user equipment for preventing call drop in a wireless network

Various embodiments herein disclose a method camping a User Equipment (UE) on a cell, the method comprising: creating a combined Most Recently Used (MRU) list by merging a list 4G MRU frequencies with a Public Land Mobile Network (PLMN) having a 5GC and a list of 5G MRU frequencies, determining whether one of a 4G cell with 5G core (5GC) and a 5G cell is available for camping by performing a MRU scan on the combined MRU list; performing one of: camping on one of the 4G cell with 5G core and the 5G cell in response to determining that one of the 5G cell and the 4G cell with 5G core is available and performing a 4G MRU frequency scan on a list of 4G without 5GC MRU frequencies in response to determining that one of the 4G cell with 5G core and the 5G cell is not available.
