Abstract: A communications method and an electronic device. In the communications method, the electronic device registers in 5G standalone (SA), and when a Wi-Fi status of the electronic device changes, if Wi-Fi is available and a Wi-Fi signal strength is good, a 5G SA mode of the electronic device is disabled, so that the electronic device does not register in a 5G mobile communications network. Then, the electronic device may register in a 4G mobile communications network.

Abstract: A data transmission management method is applied to a first electronic device that has a first link with a wireless access point. The method includes: determining, in response to a user operation, a second electronic device that performs data transmission with the first electronic device, where a second link exists between the second electronic device and the wireless access point; establishing a third link configured to perform data transmission with the second electronic device; and when a first preset condition is met, establishing a fourth link connected to the second electronic device and disconnecting the first link; or when a first preset condition is met, establishing a fourth link connected to the second electronic device and maintaining the first link, where a frequency band in which the third link is located is different from a preset frequency band. In embodiments of this application, data transmission efficiency can be improved.

Abstract: This application provides a communications system for improving a telephone call completion rate in an SA network and user equipment. According to solutions of this application, in a scenario in which calling UE resides in an LTE network or a 5G SA network and called UE resides in the 5G SA network, when the calling UE fails to call the called UE through an IMS domain, the calling and called ends cooperatively execute a call saving policy: The calling UE performs a call retry, for example, when a VoNR call or an EPS fallback call fails, falls back to LTE to initiate a VoLTE call retry, or initiates a CSFB call retry on LTE when the VoLTE call fails. The called UE falls back to the LTE network or a CS domain, and cooperates with the calling UE to complete the call. In this way, a probability that the UE successfully initiates a call can be improved, a call requirement of a user can be met, and call experience of the user can be ensured.

Abstract: Example wireless communication methods and apparatus are described. One example method includes a terminal initiates a reestablishment procedure when a handover procedure of the terminal fails. When a base station reselected by the terminal is a base station (that is, a target base station) to which the terminal is handed over in a handover procedure, and because a key of the base station is updated in the handover procedure, the base station includes key derivation information in a reestablishment message to be sent to the terminal. Therefore, the terminal can update a key of the terminal based on the key derivation information, so that the key of the terminal can be consistent with the key of the base station.

Abstract: A wearable detection device includes a main body, a first belt body, and a second belt body. The first belt body and the second belt body are connected to two sides of the main body. The main body includes a power source, a control circuit connected to the power source, and a processor connected to the control circuit. The wearable detection device further includes a flexible circuit board and a plurality of to-be-conducted chips. The flexible circuit board is disposed in the first belt body and is connected to the main body. The plurality of to-be-conducted chips are disposed in the first belt body and are connected to the flexible circuit board. When the first belt body and the second belt body are interconnected, the to-be-conducted chip positioned at a junction point is connected.

Abstract: This disclosure pertains to compositions comprising an anti-FcRn antibody, M281. The compositions include the full, intact antibody and size variants thereof that not include two antibody heavy chains and to antibody light chains. Thus, a M281 pharmaceutical composition can include: an antibody comprising a heavy chain comprising the amino acid sequence of SEQ ID NO:2 and a light chain comprising the amino acid sequence of SEQ ID NO:1, wherein the composition comprises a major protein component having a molecular weight of 140,00-145,000 Da and a minor protein component of molecular weight 118,000-120,000 Da.

Abstract: Stable pharmaceutical compositions containing an anti-FcRn antibody are described and characterized.

Abstract: A connecting mechanism includes a body and a detachable part connected with the body. The body includes a casing and a sliding component. The casing has an insertion hole for insertion of the detachable part. The sliding component is in sliding connection with the casing, and the sliding component has access holes and clamping holes in communication therewith. The detachable part includes insertion pieces. When the sliding component slides from a first position to a second position, the access holes are opposite to the insertion hole, and the insertion pieces extend into the access holes through the insertion hole. When the sliding component slides from the second position to the first position, the insertion pieces enter the clamping holes from the access holes, thereby locking the detachable part. The assembly and disassembly of the detachable part and the body are realized through the operation of the sliding component without tools.
