Abstract: The present application provides a method and an apparatus for avoiding interruptions in an on-going service. A LAN bridge intercepts a trusted port connected to a first routing bridge; determines whether the first routing bridge is forwarding or has a permission to forward data flow from a C-VLAN according to a result of the interception; and if the first routing bridge is not forwarding or no longer has the permission to forward the data flow from the C-VLAN, broadcasts the data flow from the C-VLAN to a second routing bridge so that the second routing bridge forwards the data flow from the C-VLAN. With the method provided in the embodiments of the present application, a forwarding path can be rapidly switched when a designated routing bridge is faulty and cannot carry out a traffic forwarding function or an appointed forwarder of a customer VLAN is changed.

Abstract: A data channel and an audio channel may be established between a wearable device and a terminal. When being in the earphone mode, the wearable device notifies the terminal of a current status, and receives and plays the voice message that is obtained by converting the text message and that is sent by the terminal, thereby overcoming an insufficient screen display capability of the wearable device, and enabling a user to conveniently check content of the text message in time.

Abstract: Embodiments of the present disclosure provide, for example, a Bluetooth connection method, the example method including sending, by a first terminal, a Bluetooth low energy BLE advertising message, where the BLE advertising message includes device information. A second terminal receives the BLE advertising message, and then obtains the device information. The second terminal then matches the device information with prestored device information and, if the device information successfully matches the prestored device information, initiates a classic Bluetooth connection request to the first terminal, where the first terminal then establishes a classic Bluetooth connection to the second terminal. Power consumption of BLE is low.
