Abstract:
1. A method, comprising: generating a token at a first tower in a wireless network; sending the token from the first tower to a network device; receiving, at the first tower from the network device, a list of towers that are nearby the first tower, wherein the list includes towers that are nearby the first tower that are known as valid to the network device and a respective first token associated with each of the towers that are nearby the first tower that are known as valid; receiving, at the first tower, tower lists broadcast from nearby towers, wherein each of the tower lists includes a second token associated with a respective one of the nearby towers; authenticating, at the first tower, each of the tower lists from the nearby towers by comparing the second token with the respective first token; identifying, at the first tower, each of the nearby towers whose second token fails authentication as a rogue tower that has been improperly placed within the wireless network to misroute or record traffic from or to mobile devices roaming within the wireless network; generating, at the first tower, a local tower list based on the list of towers received from the network device, but which excludes the identified nearby towers that failed authentication; and broadcasting the local tower list from the first tower to nearby towers and to nearby mobile devices.
