摘要： This application provides a method for controlling a client to go online, a network device, and a client, and relates to the communications field. This application provides a method for supporting a network side in controlling a client to retransmit an online request packet. A network device determines a sending interval of an online request packet for a client, and transmits the sending interval to the client by using an advertisement packet, so that the client retransmits the online request packet based on the interval specified by the network side. In this technical solution, the network side changes from passively responding to an online request sending behavior of the client to actively controlling the online request sending behavior of the client. Therefore, intervention of the network side in a retransmission mechanism is significantly enhanced. This helps avoid problems such as an avalanche effect, and helps improve efficiency and robustness of an entire system.

摘要： Embodiments of this application provide a wireless communications method and apparatus, and relate to the communications field, to reduce power consumption of monitoring a PDCCH by a terminal device in a carrier aggregation scenario. The method performed by a network device is: sending indication information on a first serving cell before on-duration period of a first DRX cycle, wherein the indication information comprises a bitmap including bits wherein each bit indicates not to monitor a PDCCH corresponding to at least one second serving cell or to monitor a PDCCH corresponding to at least one second serving cell; and performing third processing in the on duration period of the first DRX cycle if the indication information indicates not to monitor a PDCCH, wherein the third processing comprises at least one of the following:not sending a PDCCH on at least one second serving cell or not sending a PDCCH for the at least one second serving cell; or performing fourth processing in the on duration period of the first DRX cycle if the indication information indicates to monitor a PDCCH, wherein the fourth processing comprises at least one of the following: sending a PDCCH on the at least one second serving cell or sending a PDCCH for the at least one second serving cell. The embodiments of this application are applied to a process in which a terminal device monitors a PDCCH or does not monitor a PDCCH in a DRX cycle.

摘要： This application discloses a communications method and apparatus, to resolve a problem of a loss of terminal data related to a service requirement of one card of a dual-card terminal with only one transmit chain when the other card of the terminal is in connected state. The method includes: When a first card is in connected state and a second card is in non-connected state, a communications apparatus determines that the second card needs to enter a connected state from a non-connected state. The communications apparatus sends first information to a first device through the first card, to indicate the first device or a second device to stop sending, to the terminal, a paging message for paging the first card, or indicate a condition in which the first device or a second device is allowed to send, to the terminal, a paging message for paging the first card.

摘要： This application relates to a communications method and apparatus, and a device. A second terminal device receives a first message when the second terminal device camps on a second network device. The first message is used to indicate the second terminal device to camp on a first network device, and the first network device and the second network device correspond to different PLMNs. The second terminal device camps on the first network device. In embodiments of this application, two terminal devices camping on network devices corresponding to different PLMNs may camp on a same network device. Therefore, if the two terminal devices need to communicate through a sidelink, a mechanism such as a HARQ mechanism can be normally implemented. This improves reliability of information transmission between terminal devices.

摘要： A communications method and apparatus are provided, so that a dual-card terminal device simultaneously performs a service by using two telephone cards. The method is applicable to the communications apparatus. The communications apparatus supports a SIM card 1 and a SIM card 2. The communications apparatus includes a first communications module SIM 1 and a second communications module SIM 2. The SIM 1 corresponds to the SIM card 1, and the SIM 2 corresponds to the SIM card 2. The method includes: when the SIM 1 is in a connected state, receiving a first paging notification message from a first mobility management entity through the SIM 1, where the first paging notification message includes an identifier of the SIM 2; and sending a service request of the SIM card 2 and the identifier of the SIM card 2 to the first mobility management entity, where home PLMNs of the SIM card 1 and the SIM card 2 are the same.
