A first network device determines a first pointer value associated with a first management instance that includes at least one of network access or mobility management functions for user equipment (UE) interaction with a wireless network. The first network device installs, at a second network device, the first management instance, along with the first pointer value. The first network device changes the first pointer value in response to a first event associated with the wireless network or one or more other networks.
