Problems solved by technology
When switching between cells, the terminal uses frame stealing to send switching commands. If the terminal ping-pong switches between two cells, the ping-pong switching will generate continuous frame stealing, resulting in extremely unclear voice quality, and ping-pong switching will increase the system load. cause switching failure

Embodiment Construction
[0053] In the embodiment of the present invention, the base station acquires the number of times the terminal switches between the first cell and the second cell, and if the number of handovers is greater than the threshold of the first number of handovers, it determines that the terminal switches between the first cell and the second cell according to the number of handovers The handover frequency, so as to determine whether a ping-pong handover occurs between the first cell and the second cell according to the handover frequency. The switching frequency is the ratio of the number of times the terminal switches between the first cell and the second cell to the duration of the switching times. When the switching frequency is greater than a specific value, it is determined that a ping-pong handover occurs between the first cell and the second cell. When the number of handovers is greater than the first handover number threshold, it is further determined based on the handover fre...

The embodiment of the invention relates to the field of mobile communication, in particular to a ping-pong switching detection method and device and a switching parameter configuration method and device so as to reduce frequent occurrences of ping-pong switching. If the switching frequency of a terminal switching between a first cell and a second cell is larger than a first switching frequency threshold value, the switching frequency of the terminal switching between the first cell and the second cell is determined according to the switching frequency; when the switching frequency is larger than the first switching frequency threshold value, whether ping-pong switching occurs is further determined according to the switching frequency; accordingly, misjudgment caused by relying on the switching frequency purely is avoided, and the accuracy of judging ping-pong switching is improved. By means of the method, when it is determined that ping-pong switching occurs between the first cell and the second cell, only switching parameters from the first cell to the second cell in the first cell are maintained, so switching between the cells is achieved more accurately.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a ping-pong handover detection method and equipment, and a handover parameter configuration method and equipment. Background technique [0002] In the mobile communication system, there are a group of radio cells adjacent to each other around the user terminal. At the same time, a terminal can only communicate wirelessly with one of the cells. When the UE moves between two cells, in order to ensure the communication To ensure continuity and quality of service, the system transfers the communication link between the UE and the original cell to a new cell. Such a process is called "handover". [0003] In a mobile communication system, if there is little difference in signal strength between two cells in the coverage area of the terminal, the terminal will switch back and forth between the two cells, and this process is a ping-pong handover. When the terminal switches between ...
