1. A user equipment (UE) for handover processes between communication networks, the UE comprising:
one or more processors; and
one or more non-transitory computer-readable media storing instructions that when executed by the one or more processors, cause the UE to:
receive, by the UE, first diagnostic information;
defining a first ping-pong timer value for a first communication network based on the first diagnostic information;
determine to perform a first handover from the first communication network to a second communication network in response to:
a first reference signals received power (RSRP) value being at least less than a first threshold;
a first received signal strength indicator (RSSI) value information being at least greater than a second threshold; and
the first ping-pong timer value having expired;
receive, by the UE, second diagnostic information;
defining a second ping-pong timer value for the second communication network based on the second diagnostic information;
determining to perform a second handover from the second communication network to the first communication network in response to:
a second RSRP being at least greater than a third threshold, the third threshold different than the first threshold;
a second RSSI being at least less than a fourth threshold;
a second RSRP being at least greater than the first threshold; and
the second ping-pong timer value having expired.
