We Claim:
1. A method [600] for performing handover in a wireless communication
network, the method [600] comprising:
5 receiving, by a transceiver unit [306], a handover request associated with a
User Equipment (UE) [303] from a source base station [304s];
identifying, by an identification unit [302], one or more interfaces for
performing a handover of the UE [303] from the source base station [304s] to a
target base station [304t] based on the handover request;
10 detecting [604], by a handover manager unit [307], a failure in performing
the handover of the UE [303] to the target base station [304t] via each of the one or
more interfaces;
blacklisting [606], by the handover manager unit [307], the target base
station [304t] for a pre-defined time period upon detecting the failure in performing
15 the handover of the UE [303] to the target base station [304t]; and
stopping [608], by the handover manager unit [307], the handover of the UE
[303] and one or more UEs to the target base station [304t] during the pre-defined
time period.
20 2. The method [600] as claimed in claim 1, wherein the source base station
[304s] is a source next-generation Node Base station (source gNB) from which the
handover of the UE [303] is to be performed, and wherein the target base station
[304t] is a target next-generation Node Base station (target gNB) to which the
handover of the UE [303] is to be performed.
25
3. The method [600] as claimed in claim 1, wherein the one or more interfaces
comprise a first interface and a second interface, wherein the first interface is an Xn
interface, and wherein the second interface is one of an Ng interface or an N2
interface.

4. The method [600] as claimed in claim 1, wherein the step of detecting the
failure in performing the handover of the UE [303] to the target base station [304t]
via each of the one or more interfaces is preceded by:
performing, by the handover manager unit [307], the handover of the UE
