Embodiment Construction

[0034] 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.

[0035] 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 embodiments of the present invention aim at handover failures occurring in LTE (Long Term Evolution, Long Term Evolution) networks, and determine the real cause of the failure according to the event and measurement information reported by the UE, and then automatically adj...

Abstract

A handoff optimization method, an equipment and a system are disclosed in the present invention, wherein the method includes: acquiring an event, a working frequency point and a physical layer cell identifier of a cell related to the event and a measurement value recorded during a handoff process of a user equipment (UE); according to the event, the working frequency point and the physical layer cell identifier of the cell related to the event and the measurement value, determining a handoff failure caused by an inappropriate setting of handoff parameters and the handoff parameters needing to be adjusted; and transmitting adjustment information of the handoff parameters to the handoff related cell. With the present invention, the setting of handoff parameters can be optimized, and the probability of handoff failure occurrence can be reduced.

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 re-establishment process is proposed to remedy handover failure and reduce the probability of dropped calls. When the UE (User Equipment, user equipment) cannot access the target cell and the handover fails, if the UE detects 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. [0004] When p...
