  • Patent number: 12204896
    Abstract: In a code analysis method, a code analysis system obtains information about a service scenario that represents an objective of code analysis. The code analysis system generates a code analysis algorithm for the service scenario based on the information about the service scenario. When code analysis needs to be performed, the code analysis system obtains information about source code and object code that are specified by a user, and analyzes similarity between the source code and the object code according to the code analysis algorithm to obtain an analysis result. The similarity between the source code and the object code is analyzed according to the code analysis algorithm generated based on the information about the service scenario, to obtain the analysis result that meets a requirement of the service scenario.

  • Patent number: 11877335
    Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.
