Abstract: Disclosed are a music playing method and device. A user device is used to control another user device, to realize a music on hold (playing music in a call-hold duration) function, which reduces interaction with a SIP server, thereby reducing load of the SIP server. Softswitch (i.e., switching SDP) is established between a second user device in need of the music on hold function and a media resource server by a first user device, to realize a P2P media link between the second user device and the media resource server, which saves broadband resources of the SIP server. Also, in a situation where the media resource server needs to be deployed in another network segment (i.e., the media resource server and the second user device are in two network segments), the P2P media link can avoid configuring an access permission to a router, thus being convenient for network environment deployment.

Abstract: Method and apparatus for identifying a dual-mode wireless device, IOS device, and medium. The method includes: receiving a Bluetooth Low Energy (BLE) advertising packet from a slave device; extracting a Media Access Control (MAC) address carried in the BLE advertising packet from the slave device and that is of a master device that has established a classic Bluetooth connection with the slave device; and if the MAC address is a MAC address of a current master device, establishing a BLE connection with the slave device; or if the MAC address is not a MAC address of a current master device, ignoring the BLE advertising packet from the slave device. The method has advantages of a high identification speed and high identification accuracy. The method does not require an additional application for Apple's MFi certification, which saves certification costs, shortens the time on product development, and simplifies the production process.

Abstract: An account registration method in a Digital Enhanced Cordless Telecommunications (DECT) network cluster system includes: establishing communication with a DECT host through a DECT network cluster constructed in advance; receiving first account information allocated by the DECT host; initiating registration to a server according to the first account information, and obtaining a first registration result; sending the first registration result to the DECT host; if the first registration result is that the registration is successful, entering a first mode; if the first registration result is that the registration is not responded to, obtaining a second registration result fed back by the DECT host; if the second registration result is that the registration is successful, entering a second mode, where in the second mode, the DECT device sends SIP signaling to the DECT host so that the DECT host forwards the SIP signaling.

Abstract: The present application discloses a DECT base station, mobile terminal and system for transmitting data frame. The DECT base station comprises the first codec module and the first RF module. The first codec module is configured to store the acquired encoded data frame in the encoding buffer area of the first codec module; wherein, between the length of the encoded data frame and the length of a B-field data in the TDMA frame, there is a multiple relationship. The first RF module is configured to send, when receiving the first trigger signal, the encoded data frame in the encoding buffer area to mobile terminal. The present application can transmit data frame under the action of the trigger signal, to ensure the completeness and effectiveness of the data frame, thereby increasing the number of broadband voice communication channels.

The multimode base station in dual mode is equivalent to a base station and a DECT manager.

Abstract: The present disclosure provides a communication method, apparatus, and system for a digital enhanced cordless telecommunications (DECT) base station. The method includes: determining, based on a communication connection request sent by a handset, whether a base station satisfies a wideband (WB) voice communication requirement of the handset, and returning communication acknowledgment information; and enabling the base station to perform WB voice communication with the handset if the communication acknowledgment information is a positive acknowledgment, or enabling the base station to perform narrowband (NB) voice communication with the handset if the communication acknowledgment information is a negative acknowledgment. The present disclosure can implement WB voice communication between a DECT base station and more than six handsets.

Abstract: A debugging method for a Universal Serial Bus (USB) device includes: receiving input information of a terminal through a Human Interface Device (HID) device; when report ID of the input information is a serial port ID, transmitting the input information to a buffer of a virtual serial port Teletype (TTY) device; and extracting the input information of the terminal from the buffer of the virtual serial port TTY device, executing a shell command on the input information, and returning execution result to the terminal through an original path. The method uses a USB interface to implement a HID device, thereby realizing drive-free execution. In addition, use of the endpoint of the HID device can save endpoints needed for additional debugging and driving.
