Abstract: A method is provided for radio link failure (RLF) detection, link failure recovery, beam failure recovery (BFR) and radio link monitoring (RLM), and for interactions between modules for RLF, BFR, RLM and, integration and unification of indications. A device may measure a reference signal received over one or more communication paths of a radio link to generate reference signal measurements, and select, from the one or more communications paths, at least one path for link quality assessment of a radio link operation based on the reference signal measurements and a configured criterion. The device may generate a radio link indication based on an assessed link quality metric or a link recovery operation status associated with the selected at least one path, and send the radio link indication from a physical layer of the device to a upper layer of the device.

Abstract: Embodiments disclose a network accessing method for a mobile terminal, and a mobile terminal. In some implementation manners of the present invention, a mobile terminal reads a help request used for accessing a network by another mobile terminal; sends a beacon channel on a beacon channel resource allocated by a base station of the network, and sends a broadcast signal on a broadcast channel resource corresponding to the beacon channel resource, where the broadcast signal includes an access resource; and receives an access request of the another mobile terminal on the access resource, and assists the another mobile terminal in accessing the network.

Abstract: A system, base station and method are disclosed for detecting a radio network problem. For a handover failure occurs on a user equipment (UE), a first base station receives, problem information about the occurred handover failure from the UE, after a radio resource control (RRC) connection is reestablished or established between the UE and a cell controlled by the first base station. The first base station then transmits the received problem information to a second base station controlling a cell where the handover failure occurs. In this way, the network side can automatically identify and detect the handover failure. As such, the network can perform self-adjustment and optimization, therefore improving the network performance and satisfying use requirements of users.

Abstract: A communication method and a device are described to compress and decompress a data packet including an ethernet header to reduce radio transmission resources of an air interface. The communication method includes determining, by a sending device, a to-be-sent data packet. The to-be-sent data packet is a data packet including an ethernet header. The method further includes determining, by the sending device, a field to be compressed in the header of the to-be-sent data packet; and compressing, by the sending device, the header of the to-be-sent data packet according to a preset method. The preset method includes: removing the field to be compressed from the header of the data packet, or replacing the field to be compressed with a corresponding short field; and sending, by the sending device, a data packet obtained after the compressing.
