A method for avoiding cell pingpong reselection is disclosed in the present invention, which comprises: cells which are able to be candidate serving cells are selected, according to an S criteria, from current serving cells and adjacent non-serving cells; an optimal cell is determined, according to an R criteria, from the candidate serving cells; if the optimal cell is not the current serving cell, it is determined that whether the signal intensity and the signal quality of the optimal cell are greater than or equal to reselection thresholds, wherein the reselection thresholds are greater than the minimum serving thresholds of the serving cell; and in the condition that the signal intensity and the signal quality of the optimal cell are greater than or equal to reselection thresholds, the cell reselection is initiated. The embodiments of the present invention also provide a corresponding terminal. Since the reselection thresholds of the cell reselection are increased in the solution of the present invention, the cells with good signal intensity and bad signal quality or the cells with bad signal intensity and good signal quality will not be within the candidate range of the reselection cells, and thus the cell pingpong reselection is avoided to occur frequently effectively.

The invention relates to a method for inserting advertisements in a live video of a digital television. An operation server obtains a plurality of composing elements in any frame of an image of the live video, sets a plurality of advertisement labels for the any frame of the image, associates the advertisement labels with advertisement files, and simultaneously monitors frequencies of occurrence of the advertisement labels. By reasonably setting an advertisement playing threshold A, while a user watches the video, the advertisements having relatively large association with the video are guaranteed to be played; furthermore, the problem of the frequent advertisements due to a fact that the frequencies of occurrence of the advertisement labels are relatively large is avoided and the aversion of the user to the advertisements because the advertisements occur frequently is reduced; and meanwhile, according to the frequencies of occurrence of the advertisements, flexible adjustment is performed on the A, thereby preventing the same advertisement from occurring for many times; and the different advertisement labels are individually recorded, and are played once when a certain threshold is reached, and an advertisement playing sequence can be scattered, so the problems that many advertisements need to be played at a same time slot and are arranged difficultly are solved.

Characteristic lines A to D of lateral acceleration G-required torque T in determination of required torque T are used as switched according to increase / decrease of the absolute value of the lateral acceleration, and the direction thereof. The lines A, C used in increase of the absolute value of the lateral acceleration G are so set that the absolute value of required torque T becomes larger at the same lateral acceleration G (G≠0) than that with the lines B, D used in decrease of the absolute value of the lateral acceleration G. The difference between line A and line B (the difference between line C and line D as well) at the same lateral acceleration G is so set that the difference near the lateral acceleration of 0 is smaller than that in the other regions. Particularly, it is preferable to set the required torque T to 0 at the lateral acceleration G of 0.

The invention discloses a wired communication method supporting multiple users. All users in each group of subnets are grouped. After grouping, all users in each group obtain a frequency band including the frequency points used by the group, priority, and maximum The channel competition configuration of contention window, maximum backoff window, and upper and lower limits of the time slots that can be accessed; the central node determines the channel competition configuration of the group according to the number of users in different groups and the success rate of transmission under the group, and uses the The success rate of PRS contention in a group determines the channel contention configuration of the group. The invention overcomes the situation that the speed of the existing power carrier equipment drops significantly when a large number of users exist, and designs a user access mechanism that can support a large number of users to access the power carrier device at the same time.
