Problems solved by technology
[0003] However, in the process of implementing the embodiments of the present invention, the inventors found that when both the serving cell and the target cell need to adjust the handover boundary, the handover boundary of the serving cell and the target cell will all change, and this change of the handover boundary will inevitably will affect both
For example figure 1 As shown, if the two cells of serving cell A and target cell B shrink the handover boundary at the same time, this will cause figure 1 The handover zone on the right becomes narrower or even has no handover zone, which will cause problems such as ping-pong handover and handover failure; figure 1 As shown on the left, the switching band is too large, resulting in problems such as overlapping coverage

Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0047] In the first aspect, an embodiment of the present invention provides a handover parameter optimization method, such as figure 2 shown, including:
[0048] S101. In the current optimization period, obtain an updated handover parameter adjustment list, and the elements in the list are used to represent the difference between the handover parameters suggested to be adjusted by the current cell and the current handover parameters relative to its neighborin...

The embodiment of the invention relates to a switching parameter optimization method and device, electronic equipment and a computer readable storage medium. According to the method, firstly the element in the updated switching parameter adjustment list for representing the switching relationship between a cell and a neighboring cell is obtained; and if it is judged that the element does not meetthe constraint condition of reserving the switching band size between the two cells, the element is adjusted until the element meets the constraint condition. Therefore, the change of the switching band between each cell and its neighboring cell in case of switching boundary adjustment can be limited by constraining the corresponding switching element between each cell and the neighboring cell toensure that the change of the switching band is more appropriate, the situation that the switching band is excessively large or narrow or even no switching band due to the blind change of the switching boundary between the two cells can be avoided, and the adjustment effect of parameter optimization can be better guaranteed.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for optimizing handover parameters. Background technique [0002] In the handover process of the existing network, due to the unreasonable setting of the handover boundary, it will cause premature handover, too late handover, handover to the wrong cell, and ping-pong handover. Therefore, the mobile robustness optimization is defined in the 3GPP protocol ( The concept of MRO) stipulates the definition of premature handover, too late handover, and handover to the wrong cell from the protocol. Manufacturers can analyze the direction of parameter adjustment according to the problems in the existing network, and reduce the problem by speeding up or slowing down the handover happened. [0003] However, in the process of implementing the embodiments of the present invention, the inventors found that when both the serving cell and t...
