Abstract: This application provides a cell selection method, a cell reselection method, and a chip, to improve user experience. The cell selection method includes: A terminal device searches for a first candidate cell, and receives a system message of the first candidate cell, where the system message includes parameter information of the first candidate cell and bandwidth information of the first candidate cell, and the bandwidth information is used to indicate a bandwidth of the first candidate cell. The terminal device determines a cell selection reception level value Srxlev and a cell selection quality value Squal of the first candidate cell based on cell measurement values and the parameter information of the first candidate cell, and determines that Srxlev>0 and Squal>0. When the bandwidth of the first candidate cell is greater than a preset threshold, the terminal device camps on the first candidate cell.

Abstract: A caller identification display method includes a terminal device sending a first request to a server of a first application, where the first request is used by the terminal device to subscribe to a first service. After receiving the request sent by the terminal device, the server of the first application sends a first response to the terminal device. The server of the first application sends a first number to the terminal device. The terminal device obtains an association relationship between the first number and the first application. When the terminal device makes a call or receives an incoming call, the terminal device displays a first call interface, where the first call interface includes prompt information, and where the prompt information includes the association relationship between the first number and the first application.

Abstract: The vehicle diagnostic system includes a key management system and a to-be-diagnosed unit. The key management system receives a key authorization request sent by a diagnostic device, generates a temporary key based on the key authorization request, and sends a key authorization response to the diagnostic device. The key authorization response carries the temporary key. The key management system configures the temporary key for the to-be-diagnosed unit, so that the diagnostic device and the to-be-diagnosed unit complete a diagnostic based on the temporary key and obtain a diagnostic result. The temporary key is independent of a long-term key in a vehicle. The temporary key is configured to complete the vehicle diagnostic, so that the diagnostic device can be prevented from accessing the long-term key in the vehicle as much as possible.

Abstract: This application provides a cache decision method and apparatus. The method includes: receiving, by a policy control function PCF, first cache information sent by at least one local analytic function LAF. The first cache information includes a base station identifier, identifiers of first N1 pieces of application information that are accessed for a maximum quantity of times, and content corresponding to the identifiers of the N1 pieces of application information, where N1 is a positive integer. The method further includes determining, by the PCF, local cache content based on the first cache information and a capacity of a local cache. In this way, the cache hit rate can be effectively improved, transmission bandwidth and data transmission overheads can be greatly reduced, and users' experience improved.

Abstract: The present disclosure provides a system for storing encrypted data. The system comprises a server and a plurality of clients. A first client of the plurality of clients is configured to send to the server a first reference value calculated from data to be encrypted and stored. The server is configured to determine a group of second clients from the plurality of clients, the second clients having each sent to the server data with a second reference value equal to the first reference value. The group of second clients is configured to perform a passive key exchange protocol with the first client, and the server is configured to determine, based on a result of the passive key exchange protocol, whether the data is to be stored in full or as deduplicated data.

Abstract: A method and system for compensating for a doubly selective channel, and a related apparatus are applied to the field of communications technologies. In embodiments of the present invention, a receive end obtains, based on a minimum mean square error between a transmit pilot sequence and a receive pilot sequence, an optimal parameter used in a process of channel compensation and signal modulation, that is, a modulation order and a channel compensation parameter such as a channel compensation matrix. Therefore, according to the embodiments of the present invention, an optimization method is used to apply a banded equalization channel compensation method and a partial FFT transform to a communications system, thereby improving system performance.
