A wireless relay network to serves User Equipment (UEs). Wireless relays wirelessly attach to wireless base stations and exchange relay core signaling with relay cores. The wireless relays establish relay bearers from the wireless relays to UE cores over the wireless base stations and the relay cores. The wireless relays wirelessly attach the UEs and exchange UE core signaling with the UE cores over the relay bearers. The wireless relays establish UE bearers from the UEs to the UE cores over the relay bearers. The wireless relays exchange UE data between the UEs and the UE cores over the UE bearers.
