Abstract: Embodiments of the present invention relate to the communications field, and disclose a data transmission method and device to resolve a problem that a success rate of receiving data by an MTC terminal is relatively low after an SC-PTM technology is introduced. A specific solution is as follows: A base station device sends first control information to a terminal device, where the first control information is used to control repeated transmission of multicast service data; and the base station device sends the multicast service data to the terminal device according to the first control information. The present invention is used in a data transmission process.

Abstract: A method for updating a SELinux security policy and a terminal. The method includes receiving, by the terminal, a security policy file sent by a server. The method further includes, performing, by the terminal in a power-on status, storing the security policy file in preset storage space by using a first service or process, modifying, by the terminal, a value of a preset attribute value from a first value to a second value by using the first service or process, reading, when it is detected that the value of the preset attribute value is changed from the first value to the second value, the security policy file from the preset storage space by using a second service or process and writing the security policy file into a memory, and loading, by the terminal, the security policy file in the memory by using the second service or process.

Abstract: A control information communication method, a base station, and user equipment are provided. A determination is made whether downlink control information (DCI) is used for multicast transmission or for paging. When the DCI is determined to be used for multicast transmission, the DCI is scrambled by using a single cell radio network temporary identifier (SC-RNTI). The DCI includes indication information and scheduling information, the indication information indicating whether a multicast control channel is updated. When the DCI is determined to be used for paging, the DCI is scrambled by using a paging radio network temporary identifier (P-RNTI). The scrambled DCI can be sent to user equipment by using a first downlink control information format.

Abstract: A coding method and apparatus are provided. The method includes: coding an information bit by using a preset generator matrix of a systematic (U|U+V)-code to obtain a codeword of a systematic code. The preset generator matrix of the systematic (U|U+V)-code includes a first identity sub-matrix of a U code and a second identity sub-matrix of a V code. A plurality of elements in a same column as the first identity sub-matrix are all 0. A plurality of elements in a same column as the second identity sub-matrix are all 0.

Abstract: The present disclosure relates to an interface generation method. In one example method, an interface generation apparatus obtains a service requirement of a user. The interface generation apparatus determines, based on the service requirement of the user, interface elements for implementing the service requirement and an association relationship between the interface elements for implementing the service requirement. The interface generation apparatus generates a user interface based on the interface elements for implementing the service requirement and the association relationship between the interface elements for implementing the service requirement.

Abstract: Embodiments of this application disclose a method for authenticating an access network device. The method includes a terminal device sends an authentication request to the access network device. The terminal device receives, in a first transmission time unit, a first authentication request response in response to the authentication request. The terminal device obtains first time window information in the first authentication request response. The first time window information indicates a time range in which the terminal device receives the first authentication request response and a first time window indicated by the first time window information comprises at least one transmission time unit. The terminal device determines that the access network device is a legal access network device when the terminal device determines that the first transmission time unit falls within the first time window.
