Claim of US Patent No. 10,172,139

1. A first mesh application system located within a first, local, mesh node comprising:a. a database storing: (1) routing information to route data packets of user equipment (UE) between the first, local, mesh node and a second, remote, mesh node via an IP tunnel, (2) IP addresses associated with both local UEs associated with the first, local, mesh node and remote UEs associated with the second, remote, mesh node, the second, remote, mesh node associated with a second mesh application system; (3) UE service parameters, and (4) a sub-band allocation database storing physical frequency sub-bands used by both local UEs associated with the first local, mesh node and remote UEs associated with the second, remote, mesh node; and
b. a processor executing computer readable program code stored in computer memory to implement an application to: (1) exchange data packets and control messages within the IP tunnel with the second, remote, mesh application system associated with the remote, second, mesh node, (2) periodically exchange resource allocation update control messages between the first and second mesh application systems within the IP tunnel to coordinate resource assignment to radio access UEs and backhaul UEs between the first and second mesh nodes, and (3) give periodical decisions on assignment of frequency sub-bands to radio access UEs of the first, local, mesh node not reserved/used for backhaul UEs and not assigned to radio access UEs of the second mesh node, and (4) give periodical decisions on assignment of frequency sub-bands to backhaul UEs based on combination/summary of messages received from the second, remote mesh node by avoiding in-use backhaul frequency sub-bands.
