Description

Cell selection method, system and related device Technical Field The present application relates to the field of communications technologies, and in particular, to a cell selection method, system, and related devices. Background Nowadays, in places with dense crowds such as gymnasiums, concerts and stations, the number of terminals is too large, so that communication resources in a cell are tense, and the communication quality of terminal users is further affected. One current strategy is to reduce the number of terminals in a single cell by reducing the transmit power of some of the base stations and thus the coverage of the base stations. However, this reduces the link quality of the base station itself, further compromising the communication experience of the terminal hosting the base station. Meanwhile, terminals which are urgent to change base stations usually only use signal strength as a basis for selecting the base stations, blind residence of cells with strongest nearby signals is performed, and finally the resided cells are often not cells with optimal communication experience, so that the overall communication quality of users is reduced. Disclosure of Invention The application provides a cell selection method, a system and a device, which select a cell which is finally resided through the type of the execution service of a terminal and the capability information of the cell, and consider factors are more various and comprehensive, so that the cell with better service experience can be resided, and smoother communication experience is obtained. The problem of how to select a cell with better communication quality by the terminal is solved. In a first aspect, the application provides a cell selection method applied to a terminal, wherein the method comprises the steps of residing in a first cell and executing a first service, and the type of the first service is a first type. If the first service is detected to be blocked, searching a first cell list, wherein the first cell list comprises one or more cells, and the one or more cells in the first cell list comprise a second cell. Capability information of one or more cells in a first cell list is acquired. The second cell is camped on based on the first type and capability information of one or more cells in the first cell list. In this way, the terminal selects the cell to be resided together through the type of the executed service and the capability information of the cell, the consideration factors are more comprehensive and various, and the selected cell is more suitable for the application scene of the terminal. Under the conditions of serious network congestion and interference, the terminal can efficiently determine the cell more suitable for executing the first service, and realize higher throughput rate and better service experience. In one possible implementation, after camping on the second cell based on the first type and the capability information of one or more cells in the first cell list, the method further comprises continuing to perform the first service at the second cell. In this way, the terminal can continue to execute the first service in the second cell with better communication quality, and service experience of the first service is improved. In one possible implementation, the signal strength of one or more cells in the first cell list is greater than the first signal strength. In this way, the terminal can select the resident cell from the cells with the signal strength larger than the first signal strength, and the probability of better communication quality of the selected cell can be improved. In one possible implementation manner, the method further comprises executing a second service in a second cell, wherein the type of the second service is a second type which is different from the first type, searching a second cell list if the second service is detected to be blocked, wherein the second cell list comprises one or more cells, one or more cells in the second cell list comprise a third cell which is different from the second cell, acquiring capability information of one or more cells in the second cell list, and camping on the third cell based on the second type and the capability information of one or more cells in the second cell list. Therefore, after the terminal switches the resident cell, the type of the execution service and whether the network performance index of the service meets the corresponding conditions can be detected in real time, the throughput rate of the terminal for executing the service is improved, and the user experience is improved. In one possible implementation, the capability information is used to indicate the load level and/or the interference level of the cell. In this way, the signal strength of the cell is high, which cannot fully represent the communication quality of the cell, and part of the signal strength is lower, but the cell with lower load degree and/or interference degree
