  • Patent number: 9503921
    Abstract: Embodiments of the present invention relate to a method for determining a scrambling code conflict and an apparatus for determining a scrambling code conflict. The method includes: determining a serving cell before a handover of a user equipment fails, and determining a current serving cell of the user equipment; and comparing frequencies and scrambling codes of the current serving cell and a neighboring cell of the serving cell before the handover fails, and determining, according to a result of the comparing, that a scrambling code conflict exists between the current serving cell and the neighboring cell of the serving cell before the handover fails. A probability of a handover failure of a user equipment is reduced, so as to ensure that a service of the user equipment runs normally.

  • Publication number: 20160286414
    Abstract: Embodiments of the present invention provide a method and an apparatus for optimizing a neighbor relation. The method for optimizing a neighbor relation in the present invention includes: determining, by a centralized device, to-be-processed neighboring cells according to a preset rule, generating an optimization suggestion according to the determined to-be-processed neighboring cells, and delivering the optimization suggestion to a radio network controller RNC, so that the RNC optimizes the to-be-processed neighboring cells according to the optimization suggestion. According to the embodiments of the present invention, automatic optimization of the neighbor relation is implemented.

  • Publication number: 20120175661
    Abstract: A semiconductor light emitting package includes a substrate, an encapsulating material, a semiconductor light emitting chip disposed on the substrate, wires; and an integrated glass-fluorescent powder compound light-emitting structure. The encapsulating material and the integrated glass-fluorescent powder compound light-emitting structure are packaged on the semiconductor light emitting chip, the integrated glass-fluorescent powder compound light-emitting structure is coated on the encapsulating material. The semiconductor light-emitting package has a large light-emitting area, high uniformity which can effectively avoid “halo” phenomenon, and long working life. The present invention also relates to a method for manufacturing semiconductor light emitting package, which can be implemented at low temperature and improve the reliability and the stability of the light-emitting property of the compound light-emitting structure.
