Abstract: Methods and systems are described for detecting and reporting a vulnerability fix in a code repository. A commit obtained from the code repository is preprocessed to generate file-level token sequences each representing a file-level code change for respective files. Respective file-level code change embedding vectors are generated by inputting each file-level token sequence into a transformer model, each file-level code change embedding vector being a vector representation of the file-level code change for the respective file. The file-level code change embedding vectors are combined into a commit-level code change embedding vector that represents all code changes contained in the commit. A predicted commit-level vulnerability fix score is generated by inputting the commit-level code change embedding vector into a classifier. A vulnerability fix report is outputted, containing an identification of the commit and the predicted commit-level vulnerability fix score.

Abstract: Embodiments of this application provide a network slice selection method. The method includes: A first network device obtains user characteristic information of a current user of a first terminal, where the user characteristic information includes one or more pieces of single network slice selection assistance information S-NSSAI corresponding to the current user. The first network device determines, based on the user characteristic information, allowed NSSAI corresponding to the first terminal, where the allowed NSSAI includes the one or more pieces of S-NSSAI; or when the first network device does not support serving a network slice indicated in the one or more pieces of S-NSSAI, the first network device determines, based on the one or more pieces of S-NSSAI, a second network device that supports serving the network slice indicated in the one or more pieces of S-NSSAI.

Abstract: The present application discloses an access method, apparatus, device, and system, and belongs to the field of communications technologies. The method includes: receiving, by a selection function entity SFE, an access request of user equipment UE sent by a radio access network node RAN node; determining a usage type of the UE based on the access request of the UE; and selecting, for the UE based on the usage type of the UE, a node that is in a dedicated core network and that can serve the UE, where the node that is in the dedicated core network and that can serve the UE corresponds to the usage type of the UE. Therefore, a node accessed by the UE is the node in the dedicated core network corresponding to the UE, and this ensures that the node can complete security verification of the UE.

Abstract: The present invention discloses a congestion control method and apparatus. A priority of a DCN type supported by a core network is defined. When a DCN node is congested, congestion control may be first performed on a DCN type having a low priority. Therefore, access by UE of the DCN type having a low priority is prevented, and normal access by UE of a DCN type having a high priority can be ensured. In addition, it can be avoided that the DCN node monitors a load status of each supported DCN type, thereby reducing policy complexity of the DCN node. Furthermore, it is avoided that the DCN node is not congested but a particular type of DCN is congested, thereby improving resource usage.
