This invention relates to a method for distributing services in a hierarchical network including: distributing low speed service to a macro-area in large cover sphere and small volume by the kind of the area and the kind of the service applied by the user so as to eliminate the interference to the users in the micro-areas by the low speed service, distributing the high speed data service to the micro-areas in small cover conditions and better channel conditions to provide high quality data transmission for the high speed data service.

The invention discloses a method, a piece of equipment and a system for selecting a service cell and belongs to the field of communication. The method comprises the following steps: strong-interference terminals of one or more corresponding micro base stations among terminals served by a macro base station are determined, wherein the one or more micro base stations are arranged in a macro cell served by the macro base station; and uplink communication of the determined strong-interference terminals is switched to micro cells served by the corresponding micro base stations so as to take the micro cells served by the corresponding micro base stations as uplink service cells of the strong-interference terminals. The strong-interference terminals of the corresponding micro base stations are determined among the terminals served by the macro base station, and the micro cells served by the micro base stations are taken as the uplink service cells of the terminals, which can reduce the transmission power and power consumption of the terminals; and meanwhile, the interference to the micro base station is reduced, and the service performance of the micro base station is improved. In addition, after the terminals are switched to the micro cells, the macro cell can allocate more time-frequency resources to other terminals in the service range, thus improving the service performance of the macro cell.

The invention relates to a car networking data transmission route selection optimized method based on electronic eyes. The car networking data transmission route selection optimized method comprises the following steps: (1) the electronic eyes collect traffic video images in real time; (2) a video processing module extracts traffic parameters according to the traffic video images; (3) a cloud computing platform affirms traffic flow state information according to the traffic parameters by combining the national road service level table; (4) a roadside unit broadcasts the traffic flow state information to car nodes, after each car node receives the traffic flow state information, the car nodes are adjusted in a self-adaptation mode and send the broadcast cycle of beacon news; (5) a car source node confirms crossroads where a data transmission route connected between the car source node and a car destination node may pass through according to an electronic map; and (6) the car source node selects the optimized route to send data according to the traffic flow information among the crossroads where the data transmission route may pass through. Compared with the prior art, the car networking data transmission route selection optimized method based on the electronic eyes has the advantages of being reliable in communication, high in promptness of data transmission, and the like.

The invention discloses an admission control method. The method comprises the following steps: receiving a request message for requesting admission of a service in the current admission control period; judging the type of service for admission which is requested by the request message; admitting non-real-time service of the request in case the type of the requested service for admission is of non-real-time service; determining admission priority of the requested real-time service in case the type of the requested service for admission is of real-time service; judging whether real-time serviceresources are available for the request based on the determined admission priority; and admitting the requested real-time service when a judgment result is that the real-time service resources are available for the request. Correspondingly, the invention further discloses an admission controller, a method for allocating resources for a real-time service and a device thereof, as well as a method for determining priority of resource allocation and a device thereof. The proposal can help meet various new requirements brought forward by next generation wireless communication system for admission control.
