Embodiment 1

[0042] The following combination figure 2 The specific processing procedure of the parameter adjustment method in the embodiment of the present invention is described.

[0043] S101, determine whether the terminal A has entered the connection state (CONNECT), if it has entered the connection state, perform the next step S102;

[0044] Among them, when the terminal needs to perform business, it enters the connection state, interacts with the network and processes data transmission; when the terminal has no business, it enters the idle state (IDLE), and monitors paging and other messages sent by the network;

[0045] S102, after terminal A enters a cell (denoted as cell I), if terminal A switches between two inter-frequency cells (such as cell I and cell II) and meets the first ping-pong handover judgment condition, determine terminal A A ping-pong switch occurs, and the next step S103 is performed;

[0046] In the embodiment of the present invention, the first ping-pong hand...

Embodiment 2

[0063] The main difference between this embodiment and Embodiment 1 is that the terminal B in this embodiment performs ping-pong switching between multiple different-frequency cells, and the following takes three different-frequency cells (cell I, cell II, and cell III) as an example. describe.

[0064] In this embodiment, the above-mentioned first ping-pong handover judgment condition becomes: within the first predetermined time period, the number n of handovers between three inter-frequency cells by terminal B is greater than or equal to the preset threshold, and terminal B is considered to have handovers between three inter-frequency cells. Ping-pong switching;

[0065] Wherein, each time the terminal B performs handover in the three inter-frequency cells, the number n of handover occurrences is increased by 1;

[0066] In this embodiment, the aforementioned second ping-pong handover determination condition becomes: within the second predetermined time period, terminal B s...

Embodiment 3

[0070] In this embodiment, the tracking area code TAC of cell I is different from the TAC of cell II. When terminal C switches from cell I to cell II and finds that the TAC has changed, terminal C initiates a tracking area update TAU request (Tracking AreaUpdate request) to the network to inform the network, such as image 3 As shown in the schematic diagram of the terminal reporting effect, the terminal C reports the measurement report MR until the TAU update is completed.

[0071] The above-mentioned process terminal C needs to perform frequent data interaction with the network.

[0072] At this time, terminal C performs a ping-pong handover between inter-frequency cell I and cell II, and each handover will trigger terminal C to initiate a TAU request. Electricity intensifies.

[0073] In this case, terminal C executes the parameter adjustment method of the embodiment of the present invention, specifically as follows:

[0074] S201, determine that the terminal C is in the...

Abstract

The embodiment of the present invention discloses a parameter adjustment method, device, terminal and storage medium. The method includes: if the terminal switches between multiple cells, determine a cell among the multiple cells as the terminal the primary cell of the primary cell; wherein, at least two of the multiple cells are inter-frequency cells; at least one of the multiple communication parameters of the terminal is adjusted so that the terminal operates on a frequency corresponding to the primary cell The receiving performance value of the point increases; if the preset stop condition is reached, the parameter adjustment is stopped. By using the embodiment of the present invention, frequent cell switching can be prevented by adjusting terminal side parameters.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular to a parameter adjustment method, device, terminal and storage medium. Background technique [0002] Cell handover is an important content of the mobility management of the wireless cellular communication system, and the success rate of handover is an important indicator of the mobility management performance of the wireless cellular communication system. [0003] In the case of coexistence of networks of different standards, the handover between cells is more frequent and complicated, the probability of handover failure increases, and it becomes more difficult to find the cause of handover failure. There is a situation where the user terminal is located in the adjacent area of ​​two adjacent cells, and each cell is configured with the other as its own neighboring cell. Due to a certain degree of signal fluctuation, the user terminal will b...
