Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0030] In the process of realizing the present invention, the inventors found that the handover failure is usually caused by the loss or error of related signaling between the UE and the network side, and the cause of the loss or error of the related signaling is mostly due to inappropriate parameter settings , or the planning of the network (including sites or antennas) is unreasonable, or the rapid movement of users, etc. For this reason, the embodiment of the present invention aims at the handover failure phenomenon that occurs in the LTE (Long Term Evolution, Long Term Evolution) network, and determines the real cause of the failure according to the events and measurement information reported by the UE, and t...

Abstract

The invention discloses a switching optimization method, equipment and a system. The method comprise: obtaining an event recorded by user equipment (UE) in the switching process, a working frequency point of a cell relevant to the event, physical layer identification and a measured value; according to the event, the working frequency point of the cell relevant to the event, the physical layer identification and the measured value, determining switch failure caused by improper switching parameter setting and the switching parameter required to be adjusted; and sending the switching parameter required to be adjusted to the cell relevant to switching. The invention can optimize the setting of the switching parameter and reduces the probability of switching failure.

Description

technical field [0001] The present invention relates to communication technology, in particular to a switching optimization method, equipment and system. Background technique [0002] In mobile networks, handover failure is an obvious problem. Because handover failure usually causes call drop and seriously deteriorates user experience, an important goal of network optimization is to reduce the probability of handover failure. [0003] In the current 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) Rel-8 protocol, an RRC connection reestablishment process is proposed to remedy handover failure and reduce the probability of call drop. When the UE (User Equipment, user equipment) cannot access the target cell and the handover fails, if the UE detects that there is a problem with the radio link and cannot recover within the set time, the UE will perform RRC (Radio Resource Control, Radio Resource Control) connection re-establishment process.
