  • MULTI-LINK GROUP ADDRESSED TRAFFIC TRANSMISSION METHOD AND APPARATUS
    Publication number: 20230071851
    Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.

  • SIM CARD SWITCHING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
    Publication number: 20220337992
    Abstract: An objective of this application is to provide a SIM card switching method and apparatus, and an electronic device, so that the electronic device can quickly and accurately perform SIM card switching. The electronic device comprehensively determines, based on a use status of a radio frequency and a network connection status, whether a SIM card needs to be switched. When the radio frequency is used by a specific service, a network connection is temporarily abnormal. However, this temporarily abnormal network connection does not affect operation experience of a user. In this case, if the SIM card is switched, traffic of the SIM card is wasted, and time consumption during SIM card switching also increases a user operation delay. Consequently, determining whether to switch the SIM card only based on the network connection causes incorrect SIM card switching. In this application, incorrect SIM card switching can be avoided.
