Disclosed are an access method and device in a heterogeneous network for solving the problem that, in network selection of a heterogeneous wireless network, a user can only enjoy at any one time the service of one network and cannot simultaneously enjoy the services of different networks, the method comprising: dividing access points capable of providing a service for a user equipment (UE) into at least one competition group; and determining the access overhead of the competition group, and selecting for the UE, according to the determined access overhead of the competition group, a target competition group from the competition groups for accessing. A network multi-path routing and traffic distribution model is established, such that the UE can select different access methods, thus providing a new traffic operation mode for network development.

Access method and device in heterogeneous network

A method and a device for maintaining a Long Term Evolution (LTE) base station are provided by the embodiments of the present invention. Depending on the LTE access network system and air interface characteristics, by making a few processing flow changes in such mode or method, a wireless communication link is established between a network maintenance device and a base station to implement the base station maintenance and data communication. Application of the technical solutions provided by the embodiments of the present invention can implement the base station maintenance and data communication by the wireless mode, reduce the cost of the network maintenance and prevent the destruction and influence of human factors on the operation and maintenance of the base station.

Method and device for maintaining long term evolution base station

A system and a method for controlling traffic, the method comprising: when a sensing terminal sends a wireless signal, the intensity of the wireless signal sent by the sensing terminal is determined by wireless sensor nodes () located on both sides of a road, and the determined intensity is passed to an information processing module (); the information processing module (); the information processing module () controls the state of a traffic light according to the change in the intensity determined by the wireless sensor nodes (). By means of the present application, the state of pedestrians crossing the road can be automatically determined, and the traffic light can be automatically adjusted, so as to ensure the safety of pedestrians effectively.

System and method for traffic control

The invention discloses a method for transmitting data between a radio equipment (RE) and a radio equipment control (REC) of a radio base station via Ethernet. The method comprises in adaptive physical layer, adapting data frames complying with a remote radio protocol to Ethernet data frames that are suitable for transmission over Ethernet physical layer, and transmitting the adapted Ethernet data frames over the Ethernet physical layer.
