Problems solved by technology

However, the blind search will interrupt the ongoing service of the UE. If the interruption is too long, the user experience will be degraded. Therefore, the Long Term Evolution (LTE) system defines the maximum threshold of the interruption delay (Tsearch), that is, the UE must be in the Complete the blind search process of the target cell and its corresponding beam within Tsearch, otherwise trigger the process of handover failure
[0004] The current NR system adopts a unified Tsearch for some services, which may cause service interruption

Embodiment Construction

[0039] In the NR system, when the UE performs handover, when the target cell and its corresponding beam are the cells and beams that the UE has synchronized before, the UE can directly initiate access according to its synchronization information. When the target cell and its corresponding beam are cells and beams that have not been synchronized or measured by the UE before, the UE needs to perform a blind search for the target cell and its corresponding beam. However, the blind search will interrupt the ongoing service of the UE. If the interruption is too long, the user experience will be degraded. Therefore, the LTE system defines Tsearch, which is 80cm by default, that is, the UE must complete the blind search of the target cell and its corresponding beam within Tsearch. Search process, otherwise trigger the process of handover failure.

[0040] The current NR system adopts a unified Tsearch configuration, which cannot meet the flexibility requirements of NR service delay, ...

Abstract

The invention discloses methods for configuring and acquiring an interrupt time delay, a base station, user equipment and a readable medium. The method for configuring the interrupt time delay comprises the steps of determining a maximum threshold of the interrupt time delay according to a current service type of the UE; and sending the maximum threshold of the interrupt time delay to the UE through an RRC message. By applying the scheme, maximum thresholds of different interrupt time delays can be configured according to service types, so that the problem of service interruption caused by unified Tsearch configuration is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method for configuring and acquiring an interruption delay, a base station, a user equipment, and a readable medium. Background technique [0002] In the 5G new radio (New Radio, NR) system, when the user equipment (User Equipment, UE) performs handover (handover), it needs to be accurate to the beam (beam) level, that is, it needs to perform the measurement of the beam of the target cell in the original cell, and report For the measurement report of the target cell beam, the base station selects the target cell and its corresponding beam according to the reported measurement report, and notifies the UE to perform handover. [0003] When the UE performs handover, when the target cell and its corresponding beam are the cells and beams that the UE has synchronized before, the UE can directly initiate access according to its synchronization information. ...
