Abstract
Distributed node systems and methods provide emergency call services to users indoors. A distributed node can be located in a building and configured to receive call requests from users in the building. The distributed node can transmit call requests to a central node that relays the call requests to a wireless network. The distributed node can also transmit node identifying information with the call request, which may be relayed to the wireless network. The wireless network can determine that a call request is a request for an emergency call and obtain location information and emergency services provider routing information based on a node identifier. The wireless network can transmit the location information to the emergency services provider using the emergency services provider routing information and set up the requested call.
