Shifting video code rate regulation method based on experience qualitative forecast

The invention relates to a shifting video code rate regulation method based on experience qualitative forecast. According to the invention, a sending end divides an encoding video speed rate into four grades, when a mobile terminal user requires a video business, the scale of the initial code rate of a video is middle, and thus, a QoE prediction model is periodically utilized to calculate a user taste value; the predicted QoE value and the presupposed QoE threshold value are compared, if the user experience quality is lower than the threshold value, and the corresponding adjustment is performed according to the network congestion indication and encoding video speed rate fedback by a receiving end in two periods; and the code rate grade of the next period is output until the request is finished, wherein the QoE prediction model is positioned on a video server side, and the decision tree structure is improved through training a plurality of gradients. The shifting video code rate regulation method provided by the invention can be used for solving a problem that in the current code rate regulation method, the video quality subjective feeling of users can not be considered, a network resource is fully utilized, meanwhile, the generation of network congestion is avoided or slacked, and the taste quality of the users is effectively improved.

The invention discloses a multi-functional toll collection lane controlling and managing system of toll roads. An industrial personal computer, a car controlled machine, an IC (integrated circuit) card reader, a toll special keyboard and a display screen at an entrance lane direction are arranged in a toll booth; an entrance lane IC card automatic card sender and an entrance lane full-automatic toll data wireless emitter/receiver are arranged at the right side of the toll booth; the industrial personal computer, the car controlled machine, the IC card reader, the toll special keyboard and the display screen at an exit lane direction are arranged in the toll booth; and an exit lane full-automatic toll data wireless emitter/receiver is arranged at the left side of the toll booth. The system of the invention can organically combine three functions of manual toll lane, ETC (electronic toll collection) lane and automatic card sending and reading lane, so that various of vehicles can pass through the entrance and exit lanes of the toll station in a short time; and the system can disperse the vehicles on the square to a maximum extent without building new lanes. The system is safe and quick. In addition, the system can accelerate vehicle traffic capacity and reduce labor intensity of the toll staff.

Method for processing discontinuous reception period in machine-type communication and network-side equipment

The invention provides a method for processing a discontinuous reception period in machine-type communication and network-side equipment in order to solve the problem that network congestion is easily caused by the improvement of the discontinuous reception period at present. The method for processing the discontinuous reception period in the machine-type communication comprises the following steps that the network load condition of the machine-type communication is acquired by the network-side equipment; the discontinuous reception period of a terminal is adjusted by the network-side equipment according to the network load condition of the machine-type communication; a paging message is sent to the terminal by the network-side equipment through a base station, and the adjusted discontinuous reception period is carried in the paging message so that data is reported by the terminal according to the adjusted discontinuous reception period. As the discontinuous reception period of the terminal is adjusted according to the network load condition, the data can be reported by the terminal according to the adjusted discontinuous reception period. The phenomenon that multiple terminals report data at the same time is avoided, thus solving the network congestion problem.
