Abstract: A method for determining an optical signal power change, wherein the method includes: A first optical signal that includes a plurality of wavelength signals is obtained, where the plurality of wavelength signals are distributed in a plurality of bands. Then, an optical power of each band and a center wavelength signal of each band are detected, and a preset single-wavelength transmit power and a preset coefficient are obtained. Next, an equivalent quantity N of equivalent wavelength signals is determined, and an equivalent wavelength signal corresponding to the first optical signal is determined. Further, a target power that is used to compensate for a first power change value of the first optical signal in transmission over an optical fiber is determined based on the preset coefficient, the equivalent wavelength signal, the equivalent quantity, and the preset single-wavelength transmit power.

Abstract: An information processing method and apparatus are disclosed in a multicarrier communications system. In the multicarrier communications system, a terminal is configured with a PCC and at least one SCC. A first base station in which the PCC is located transmits downlink data to the terminal by using a PDSCH on the PCC; and the first base station demodulates a PUCCH on the PCC by using a first format and a second format, to obtain feedback information sent by the terminal, where the first format is a PUCCH format used for a single serving cell, and the second format is a PUCCH format used for a plurality of serving cells. Therefore, a problem that downlink retransmission is continually performed because feedback information cannot be demodulated due to inconsistent PUCCH formats is resolved.

Abstract: A method, an apparatus, and a system for enhancing a concurrent processing capability of a wireless local area network (WLAN) are disclosed. The method includes receiving a first association request including an identifier of a first station (STA) that is from the first STA; performing association with the first STA; sending a first association query request including the identifier of the first STA to a WLAN controller; after the first STA is associated, receiving an association query response from the WLAN controller; and performing disassociation from the first STA when the association query response is used to instruct an access point (AP) not to associate with the first STA. When a large quantity of association events need to be concurrently processed, a STA is associated with at first, improving user experience.

Abstract: Embodiments relate to a network selection method and an apparatus. The method comprises: after receiving an access request message from a UE, a first core network device may send, to the UE, information about a dedicated second core network device corresponding to the UE, thereby ensuring that the UE can be attached to the dedicated second core network device according to the information about the dedicated second core network device, increasing selection accuracy when a core network device is selected for the user terminal, and avoiding occurrence of an access failure of the user terminal to the greatest extent.

Abstract: In a data transmission method, a second network device connected to a terminal device sends a first packet to a first network device, where the first packet includes a MAC address of the terminal device and a first management VLAN identifier. The first management VLAN identifier indicates a management VLAN configured for a first port on the second network device. The first port is configured to connect the second network device and the terminal device. After receiving the first packet, the first network device establishes a first association relationship between the MAC address, the first management VLAN identifier, and a first logical port based on information in the first packet, where the first logical port is located on the first network device and corresponds to the first port.
