Abstract: The present invention provides a virtual network function network element management method, apparatus, and system. A VNF resource pool management apparatus receives a VNF network element request message sent by a VNF resource pool user apparatus, where the VNF network element request message includes attribute information and a location policy of a VNF network element that is requested; the VNF resource pool management apparatus determines a first VNF network element that matches the attribute information and the location policy from the VNF resource pool; and the VNF resource pool management apparatus sends a VNF network element response message to the VNF resource pool user apparatus, where the VNF network element response message includes identification information of the first VNF network element. In this way, a risk that a functional group formed by VNF network elements cannot properly work can be avoided.

Abstract: Embodiments of the present invention disclose a method for processing network congestion. A first switch obtains total traffic that is received by a receiving port communicating with a third switch. The total traffic includes traffic that is occupied by a data flow sent by a second switch, and the first switch. When the first switch determines, according to the total traffic, that a sending port of the third switch is congested, the first switch determines a target port. The target port is another port that can receive the data flow and that is selected from receiving ports of the first switch. The first switch sends an adjustment message to the second switch. The adjustment message carries an identifier of the data flow and an identifier of the target port, and the adjustment message is used by the second switch to send the data flow to the target port.

Abstract: Embodiments of the present invention provide a resource configuration method and an apparatus. User equipment (UE) includes a receiving module and a processing module, where the receiving module is configured to receive a broadcast message sent by a control node and including at least one first resource pool, where the control node is a base station serving the UE or a group head UE of a group to which the UE belongs. The processing module is configured to receive a device to device (D2D) service or send a D2D service by using a resource in the at least one first resource pool.

Abstract: This application discloses a network operation, administration, and maintenance (OAM) method, an apparatus, and a system. The method includes: receiving a fault alarm message sent by an MP, where the fault alarm message includes fault information; determining according to the fault alarm message, a first maintenance set to which the MP belongs, where the first maintenance set includes MPs using a first OAM technology; querying an OAM database, to obtain a second maintenance set interacting with the first maintenance set, where the second maintenance set includes MPs using a second OAM technology; and sending a fault notification message to all MPs in the second maintenance set or an MP that is determined according to a policy in the second maintenance set. Therefore, a related fault alarm may be centrally notified on a management plane, and is decoupled from a specific OAM technology, thereby greatly reducing an implementation difficulty.

Abstract: Embodiments of the present disclosure provide a data transmission method, a user equipment, and a base station. The method includes: obtaining a resource element (RE) configuration, where an RE indicated by the RE configuration is a subset of the RE available for sending a channel state information reference signal (CSI-RS) and is the RE onto which a data symbol can be mapped; and receiving, according to the RE configuration, the data symbol that is sent by a base station on the RE indicated by the RE configuration. In some embodiments, a data symbol can be mapped onto the RE that is used for sending the CSI-RS, so that a UE can receive the data symbol on the RE that is used for sending the CSI-RS, thereby improving the utilization efficiency of the RE.
