US Patent 11706607 Location based routing that bypasses circuit-based networks

Methods, devices, and system related to wireless communications are disclosed. In one example aspect, a method for wireless communications includes receiving, by a network node in a communication network, a packet associated with a call that has been initiated for a user device, and determining, by the network node, location information carried in a header of the packet. The method also includes determining, by the network node using a mapping between location information and Major Trading Are (MTA) values, a MTA value corresponding to the location information carried in the header, and routing, by the network node based on the MTA value, the packet using a routing path that bypasses a circuit-switched based network.
