1. A method of operating a wireless communication network to serve a wireless User Equipment (UE) over a higher-priority Public Land Mobile Network (PLMN) and a lower-priority PLMN, the method comprising:
a wireless access node exchanging wireless communications with the wireless UE over the higher-priority PLMN;
another access node exchanging other communications with the wireless UE over the lower-priority PLMN, wherein the wireless UE switches between the higher-priority PLMN at the wireless access node and the lower-priority PLMN at the other access node;
a network controller detecting excessive PLMN-switching between the higher-priority PLMN and the lower-priority PLMN by wireless UE and responsively signaling the wireless UE to avoid the higher-priority PLMN until the wireless UE returns from idle mode; and
the other access node exchanging additional communications with the wireless UE over the lower-priority PLMN until the wireless UE enters the idle mode.
