Embodiment Construction

[0022] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0023] see figure 1 As shown, the wireless communication terminal implements a method for triggering a report of a quality measurement event, which includes the following steps:

[0024] (1) The wireless communication terminal initializes the array of the total number of quality measurement CRC data packets; the array of the total number of quality measurement CRC data packets is a two-dimensional array, the first dimension index is the wireless dedicated channel number, and the second dimension index is the number of current error CRC data packets received The modulus value obtained by performing modulus operation on the number relative to the preset number of error CRC data packets;

[0025] (2) The wireless communication terminal receives the measurement and control message from the wireless communication network side, and obtains the pre...

Abstract

The invention relates to a method for triggering reports of quality measurement events by a wireless communication terminal, which comprises the following steps: receiving a measurement and control message of a network side by the wireless terminal to acquire the preset total quantity of CRC, the preset number of bad CRC and pending times after reporting; receiving and checking statistics of real-time CRC and updating the total quantity of the current CRC received and the number of the current bad CRC received; performing modular operation by corresponding the number of the current bad CRC received to the preset number of the bad CRC; taking a modulus value as an index, and setting an element value corresponding to the index in an array of the total quantity of the quality measurement CRCinto the total quantity of the current CRC received; calculating the difference of the total quantity of the current CRC received and the current value of the array element when the elements are accessed again; and comparing the size relation of the differential values and the preset total quantity of the CRC and the pending times after reporting, so that the reports of the quality measurement events are triggered or any reports of the triggered events are not performed. The method for triggering the reports of the quality measurement events in the wireless communication terminal improves theefficiency of quality measurement evaluation, simplifies processes, and has stable and reliable operating performance and wide applicable scope.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to the technical field of wireless communication channel quality measurement and evaluation, and specifically refers to a method for a wireless communication terminal to realize a quality measurement event trigger report. Background technique [0002] The wireless terminal (UE) quality measurement is a measurement for a dedicated channel rather than a measurement for a common channel of a cell. The quality measurement means that the UE measures the BLER (block error rate) value of the downlink dedicated transport channel. The measurement report event is used to indicate that the number of error CRCs within the predefined window in the downlink dedicated transport channel is exceeded. [0003] In the prior art, a conventional statistical method is: the UE obtains the values ​​of Total CRC, Bad CRC and Pending after trigger after receiving the measurement and control mes...
