The invention provides a method and device for controlling traffic signals of intersections. The method for controlling traffic signals of intersections comprises the following steps: (1) detecting whether the road between an upstream intersection and a downstream intersection is congested or not by a congestion detector, wherein the congestion detector is arranged between the upstream intersection and the downstream intersection; and (2) if the road is congested, prolonging the time of the green light of the downstream intersection or shortening the time of the green light of the upstream intersection. When the road is congested, by prolonging the time of the green light of the downstream intersection, vehicles on the congested road can pass through the downstream intersection and run away from the congested road because of longer green light time, so that the congested road can be unblocked quickly; or by shortening the time of the green light of the upstream intersection, the number of the vehicles running on the congested road is reduced, so that the congested road can also be unblocked quickly, thereby realizing the purpose of reducing the occurrence of the phenomenon that the traffic capacity of the road network in a large range is lowered because a single intersection is congested.

The present invention sets forth a methodology for providing improved downlink backhaul services from a radio network controller (RNC) to a plurality of base stations via a backhaul network that provides Ethernet services. The Ethernet services are provided by a group of provider edge (PE) switches and regular label switch routers (referred to as P switches). Base stations within the network are assigned into clusters, each of the clusters having a cluster ID. The RNC transmits packets to a given switch or switches out on the network based on a cluster ID included within the transmitted packet. The communications traffic is then multicast from at least one last hop switch in the network to candidate base stations on the basis of the cluster ID and an active set within the cluster. Advantageously, the clusters act as subgroups for more easily directing the transmission of the backhaul multicast traffic. Significant advantages are realized through use of the present invention, including the ability to allow faster and smoother handoffs, as well as backhaul bandwidth savings since intelligence regarding cell switching is extended out at a point farther along the network than was previously enabled.
