Abstract

The invention discloses a method, user terminal and system for reselecting a carrier, wherein the user terminal extracts the high priority carrier signal quality threshold and offset from the broadcast message after receiving the broadcast message sent by the network side offset; the user terminal randomly generates a random number R; the user terminal uses the offset amount offset, the random number R, and the high-priority carrier signal quality threshold to obtain the carrier reselection threshold; the user terminal compares the current high-priority carrier signal quality with the carrier reselection The threshold is compared, and the carrier is reselected according to the comparison result. In this embodiment, the user terminal adjusts the carrier reselection threshold by controlling the offset value offset, so that the user terminal is randomly assigned to multiple carriers in the idle state, realizing load balancing of multiple carriers and avoiding multi-carrier The problem of unbalanced load among carriers in the region.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for reselecting a carrier, a user terminal and a system. Background technique [0002] The current multi-carrier idle reselection mechanism in Long Term Evolution (LTE) is to select the resident carrier according to the carrier priority and signal quality, as long as the signal quality of the high-priority carrier is higher than the threshold value, regardless of the low-priority carrier Whether the signal quality is good or bad, the user terminal reselects to a high-priority carrier when it is idle. refer to figure 1 , the user terminals in cell 1 and cell 2 need to reselect to camp on carrier f1 or carrier f2 when they are idle. The priority of carrier f1 is higher than that of carrier f2. When the signal quality on the high priority carrier is greater than Threshold Thresh x,High (Such as figure 1 When the dotted boxes in cell 1 and cell 2 are shown), t...
