Abstract: The present invention discloses a method for fast judging and optimizing light emitting quality of a light guide plate based on an image processing technology. According to the method, an illuminance diagram of the light guide plate is regarded as a single-color image, illuminance information is converted into a gray level, gray levels of all pixel points are calculated through a gray level histogram, the light outgoing quality of the light guide plate is analyzed according to a discrete degree of the gray levels, positions of the gray levels discrete in distribution in the gray level histogram on the illuminance diagram are found out through programming, a net point filling rate in a corresponding area is directly optimized and is eliminated, and a uniformity degree evaluation formula with a precision P judgment criterion is given. The present invention effectively improves the optimizing efficiency of the light guide plate, and an optimized result is closer to an actual visual effect.

Abstract: The present invention provides a method for completing smooth cut-over and a device and equipment for performing cut-over operations. The method comprises: when the device for performing cut-over operations maintains a first connection with the first cut-over device via a first interface, establishing a second connection with a second cut-over device via a second interface, and transferring the services carried on the connection resources between the device for performing cut-over operations and the first cut-over device, that is, the first connection resources, to the connection resources between the device for performing cut-over operations and the second cut-over device, that is, the second connection resources. The present invention does not interrupt services during the cut-over procedure, without affecting the normal service usage by the user, thus improving the security and reliability of cut-over.

Abstract: The present invention discloses a method and system for softly unloading a core network element in a multi-homing networking mode, for solving the technical problem of high call loss rate caused by unloading the multi-homing core network element due to reasons like upgrading, failure, or removal. In the present invention, the to-be-unloaded multi-homing core network element is set into an office direction blockage state, and the multi-homing core network element will not be distributed with a new service; and the to-be-unloaded multi-homing core network element is unloaded when the existing services thereon are processed into a predetermined state. The present invention reduces the call loss rate and mitigates the impact on the existing services when the multi-homing core network element needs to be unloaded.
