Communication in a cellular network taking into account backhaul loading

摘要

The invention deals with a method of communication in cellular networks comprising mobile user equipments (1, 2, 3, 4), base stations (5, 6, 7, 8) and core networks (9, 10), backhauls (1, 12, 13, 14, 15) between base stations (5, 6, 7, 8) and core networks (9, 10), including, if a request from or to a mobile user equipment (4) cannot be satisfied by a base station (6) of a first network through own backhaul according to traffic load thereon, the step of trying to satisfy said request through backhaul of another neighbor base station (8) of a second network different from first network, said another neighbor base station (8) being selected according at least to availability and to offered quality of service thereof.

1. A method of communication in a cellular communication network that includes a first cellular network and a second cellular network, comprising:
receiving, at a main base station of the first cellular network, a request from or to a mobile user equipment of the first cellular network; determining, by the main base station, if the request can be satisfied through the main base station's own backhaul based on traffic load by comparing an effective traffic load to a predetermined maximum traffic load threshold; and if the request cannot be satisfied through the main base station's own backhaul: attempting, by the main base station or a core network of the first cellular network, to select a neighbor base station of at least a second cellular network that is different from the first cellular network, based on at least one of an availability of a backhaul of the neighbor base station, and an offered quality of service of the backhaul of the neighbor base station; and if the attempt is successful, communicating between the main base station and the core network of the first cellular network via a backhaul of the neighbor base station to satisfy the request.
