And step 308, reporting the measurement event to the network equipment.
In the embodiment of the application, the user equipment calculates a difference value obtained by subtracting a first signal quality parameter of the serving cell from a second signal quality parameter of the neighboring cell, and determines whether the difference value is greater than a target offset value, if the difference value is determined to be greater than the target offset value, it is indicated that the signal quality of the neighboring cell is stronger than that of the serving cell, a measurement event that whether the user equipment is switched to the neighboring cell is generated, and the measurement event is reported to the network equipment, so that the network equipment switches the user equipment from the currently accessed serving cell to the neighboring cell with stronger signal quality.
As can be seen from the above, in the embodiment of the present application, when it is determined that the first signal quality parameter belongs to the parameter threshold range, that is, when it is determined that the user equipment is in a strong signal environment, first, the user equipment determines an adjustment coefficient based on the reference signal received power, the power conversion value corresponding to the reference signal received power, and the power adjustment amount; secondly, the user equipment determines a target adjustment value based on the adjustment coefficient, the adjustment coefficient threshold and the coefficient adjustment amount; and finally, generating a measurement event under the condition that the difference value of the second signal quality parameter of the adjacent cell minus the first signal quality parameter of the serving cell is greater than the target offset value, so that the network equipment switches the user equipment from the currently accessed serving cell to the adjacent cell with stronger signal quality. Therefore, the reference offset value of the measurement event is dynamically adjusted based on the signal range of the serving cell, the target offset value is obtained, frequent switching of the user equipment among the cells is avoided, the situation that network drop is caused by untimely switching under the weak network environment is avoided, the user equipment is ensured to relatively stably reside in the serving cell under the condition that the signal fluctuates in the environment of the serving cell with strong signal quality, the communication stability of the user equipment is improved, and the time delay of data transmission of the user equipment is reduced.
In this embodiment, the first signal quality parameter includes a reference signal received power and a signal-to-interference-plus-noise ratio, and the first signal quality parameter does not belong to the parameter threshold range may be understood as the reference signal received power is not greater than the power threshold, and/or the signal-to-interference-plus-noise ratio is not greater than the noise ratio threshold.
In the embodiment of the application, after receiving a configuration parameter of a measurement event and detecting a first signal quality parameter of a serving cell accessed by user equipment, the user equipment determines whether reference signal receiving power included in the first signal quality parameter is greater than a power threshold value and whether a signal-to-interference plus noise ratio included in the first signal quality parameter is greater than a noise ratio threshold value; if the user equipment determines that the reference signal received power is smaller than or equal to a power threshold and/or the signal-to-interference-plus-noise ratio is smaller than or equal to a noise ratio threshold, the user equipment determines that the first signal quality parameter does not belong to the parameter threshold range; that is to say, the signal quality of the serving cell currently accessed by the user equipment is not very strong, the user equipment is currently in a weak signal environment, the reference offset value does not need to be adjusted, and the user equipment can report the measurement event according to the reference offset value configured by the network. Specifically, the ue calculates a difference value obtained by subtracting a first signal quality parameter of the serving cell from a second signal quality parameter of the neighboring cell, and determines whether the difference value is greater than a reference configuration value, if it is determined that the difference value is greater than the reference configuration value, it indicates that the signal quality of the neighboring cell is higher than the signal quality of the serving cell, generates a measurement event indicating whether the ue switches to the neighboring cell, and reports the measurement event to the network device, so that the network device switches the ue from the currently accessed serving cell to the neighboring cell with higher signal quality.
