Abstract: A first access network device sends first configuration information to a terminal device, where the first configuration information includes multipath configuration information and a first trigger condition, the multipath configuration information includes configuration information of a plurality of second transmission paths, and each second transmission path includes a transmission link between the terminal device and one second access network device and an interface link between the first access network device and the second access network device. When a radio link between the terminal device and the first access network device meets the first trigger condition, the terminal device activates the multipath configuration information, and transmits a same RRC message to the first access network device by using a first transmission path and at least one second target transmission path. Accordingly, a same RRC message is transmitted by using a plurality of transmission paths, thereby improving RRC message reliability.

Abstract: A resource scheduling method includes: obtaining, by a terminal device, a first resource configuration parameter from an access network device; determining, by the terminal device, whether a first logical channel (LCH) supports the first resource configuration parameter, where the first LCH is an LCH on which there is to-be-sent data; and if the first LCH supports the first resource configuration parameter, determining, by the terminal device, a resource of the first LCH based on the first resource configuration parameter. According to a resource scheduling method provided in this application, after obtaining the first resource configuration parameter, the terminal device determines the resource of the first LCH by determining whether a mapping relationship exists between the first LCH and the first resource configuration parameter, to map the first LCH to the resource that matches the first LCH. This improves resource utilization.

Abstract: Embodiments of the present invention relate to the field of communications technologies, and disclose a method and an apparatus for recovering from a radio downlink failure. The method includes: monitoring a first radio link to determine whether a radio downlink failure occurs on the first radio link, where the first radio link is a currently connected radio link; if it is detected that the radio downlink failure occurs on the first radio link, starting a physical-layer-monitored automatic-recovery process for the first radio link and starting a Radio Link Control RRC connection re-setup process to set up a second radio link; and recovering from the radio downlink failure through either of the physical-layer-monitored automatic-recovery process and the RRC connection re-setup process.

Abstract: Example communication message sending methods and apparatus based on backoff duration are described. One example method includes that a terminal device sends an access request to a cell to which the terminal device belongs. The terminal device monitors a downlink control channel, and receives an access response message based on scheduling information on the downlink control channel. If the access response message carries a backoff access identifier, the terminal device determines a backoff parameter corresponding to the backoff access identifier in the access response message based on a correspondence that is pre-stored and that is between the backoff access identifier and the backoff parameter. The terminal device determines backoff duration based on the backoff parameter and an access resource interval period corresponding to the terminal device, and sends an access request to the cell after the backoff duration.

Abstract: Embodiments of the present invention disclose a photochromic lens module, a camera, and a terminal device. The photochromic lens module includes a lens module and a photochromic thin film. The lens module includes a first surface and a second surface. When the first surface is an incident surface, the second surface is a refractive surface; when the second surface is an incident surface, the first surface is a refractive surface. The photochromic thin film includes a first area and a second area. The photochromic thin film covers the first surface or the second surface. The first area uses a negative photochromic material, and the second area uses a positive photochromic material. By means of the embodiments of the present invention, a lens module can be effectively protected.
