Abstract: The present invention discloses an apparatus and a method for determining a subband resource and relates to the field of communications network technologies, so as to resolve a problem of how to ensure communication between user equipment and a base station while costs of the UE or complexity of the UE is reduced. In embodiments of the present invention, subband resource information acquired by UE is used to determine a subband resource, so that data and/or control information can be transmitted according to the subband resource. The solutions provided in the embodiments of the present invention are suitable to be used to determine a subband resource.

Abstract: An optical device comprises a transmitter module, a receiver module, and a switch comprising a first port coupled to the transmitter module, a second port coupled to the receiver module, a third port configured to couple to a transmitter fiber, and a fourth port configured to couple to a receiver fiber. A method implemented in a switch, the method comprising operating in a monitor mode that provides for monitoring of a transmitter fiber or a receiver fiber, receiving a command to transition from the monitor mode to a data mode, connecting a transmitter module to the transmitter fiber, and connecting a receiver module to the receiver fiber.

Abstract: The present disclosure provides a message processing method, an in-vehicle terminal, and a base station. The method executed by a first in-vehicle terminal includes: first, generating a safety message, where the safety message includes message content and a message type; then, determining, according to the message content and the message type, a priority value corresponding to the safety message; finally, sending, according to the priority value corresponding to the safety message, the safety message by using a vehicle direct communication physical VDC PHY layer or separately by using a cellular physical cellular PHY layer and a VDC PHY layer, so that a base station and/or a second in-vehicle terminal receive/receives the safety message, and the first in-vehicle terminal can send, under a preset delay requirement, the safety message to another in-vehicle terminal in a distance range that needs to be covered by the safety message.

Abstract: A method and system for recovering from service failure, and the method includes: sending, by a failure detecting node of a cross-domain connection service, a CALL_ID (Call Identifier) that identifies the cross-domain connection service and information on a disabled link in the cross-domain connection service to a first node of the cross-domain connection service, and performing, by the first node of the cross-domain connection service, an end-to-end connection recovery on a corresponding cross-domain connection service according to the CALL_ID and the information on the disabled link. According to the invention the end-to-end connection recovery of the cross-domain connection service can be implemented and the viability of the cross-domain connection service can be improved.
