Problems solved by technology

However, there is a disadvantage of periodic reporting, which is to occupy the signaling bandwidth of the air interface and increase the load of the air interface.
In extreme cases, the UE's periodic measurement report message occupies most of the bandwidth of the air interface, which seriously affects the performance of the system and reduces the system capacity
Therefore, periodic reporting is not a very practical reporting method and should not be used lightly

Embodiment Construction

[0023] The present invention needs to set two timers: an event reporting statistical timer Timer_event and a periodic reporting statistical timer Timer_period.

[0024] The present invention needs to use following parameter:

[0025] Event reporting granularity ΔM. This parameter determines how much the measurement result changes, and an event report is triggered. If the change of the measurement result after one report does not exceed ΔM, a new event report will not be triggered. ΔM can be set in advance according to the required measurement accuracy. If the required accuracy is high, ΔM should be set smaller. On the contrary, ΔM can be set larger.

[0026] Nevent_Thresh is the event reporting threshold for periodic reporting. The condition for converting the event reporting set by the present invention into periodic reporting is that the number of event reports received within the timing period of the timer Timer_event exceeds Nevent_Thresh.

[0027] Start event reporting ...

Abstract

A frequency test and control method relates to the WCDMA system including: after setting up calls of a user device, a radio network controller transmits a measurement control order to the user device and initiates the measurement to determine the report mode of the measurement result based on the change of the test quantity, when the test quantity changes smoothly, it applies the mode of event report and modifies the event trigger threshold based on the test result and report accuracy, when it changes quickly, it turns the event report to a period report to get real time test result of UE accurately and avoid heavy load to the air interface signaling brought with the period report.

Description

technical field [0001] The invention relates to a method for intra-frequency measurement control in a Wideband Code Division Multiple Access (WCDMA) system (hereinafter referred to as WCDMA). Background technique [0002] In a WCDMA system, the intra-frequency measurement of a user equipment (hereinafter referred to as UE) is used in radio resource management algorithms such as soft handover. The measurement quantities of the intra-frequency measurement include: pilot chip power to noise power spectral density ratio (hereinafter referred to as Ec / N0), pilot received code power (hereinafter referred to as RSCP), path loss, and the like. One or more of these measurements can be measured as desired. The reporting methods of measurement results are divided into periodic reporting and event reporting, and event reporting is further divided into 1a, 1b, 1c, 1d, 1e, and 1f events. The reporting of various events is generally related to a specific handover situation, and is trigge...
