Abstract: This application provides a method and an apparatus for making an emergency call. The method includes: obtaining location information of UE; determining, based on the local information, whether the UE is located in a home country of an HPLMN of the UE; and when the UE is located in the home country of the HPLMN, if a predetermined condition is satisfied, initiating a VoWiFi emergency call by using an IMS APN of the HPLMN, where the predetermined condition includes: the UE has completed IMS registration, and a PLMN on which the UE camps includes no emergency APN. According to the method and apparatus for making an emergency call provided in this application, a VoWiFi emergency call success rate can be increased to some extent.

Abstract: A software-defined data center, and a deployment method for a service cluster are described therein. An SDN controller manages a cluster by using a shared IP address. The SDN controller obtains an online virtual machine event that is sent by an edge switch accessed by a new online virtual machine; obtains a MAC address of the new online virtual machine, and identifies the new online virtual machine; then identifies whether an IP address of the new online virtual machine is a shared IP address; and if the IP address of the new online virtual machine is the shared IP address, deploys the new online virtual machine to a service cluster corresponding to the shared IP address. The SDN controller automatically completes creation, capacity expansion of the service cluster, so that no manual intervention from a tenant is required, and tenant experience is good.

Abstract: K classifiers and S network service processors are deployed in a network device. A network adapter receiving queue is divided into multiple queue areas. Each classifier may acquire a packet identifier from a queue area that corresponds to the classifier and is in the network adapter receiving queue, that is, the network adapter receiving queue has multiple information reading interfaces such that the K classifiers may concurrently read packet identifiers from corresponding queue areas in the network adapter receiving queue, and the K classifiers may further concurrently determine, based on the packet identifiers acquired by the K classifiers, corresponding flow queue identifiers. Related operations before the K classifiers distribute packet description information to flow queues may all be concurrently executed, and concurrent execution makes processing times of the related operations become partially or completely overlapped.

Abstract: A session information recording method, where the method is executed by a recording server, the recording server is connected to a unified communications system and configured to record a media packet and a signaling packet generated in the unified communications system where the recording server associatively records a received media packet, a received signaling packet, or a combination thereof based on a session. Hence, the method expands application scenarios of associative recording and can resolve a problem in the prior art that a media packet and a signaling packet cannot be associatively recorded in many scenarios.

Abstract: A software-defined data center (SDDC) and a service cluster scheduling and traffic monitoring method therefor. A software defined networking (SDN) controller implements a scheduling and decision function of load balancing. As a load balancer, the SDN controller follows a serving node load balancing principle, and customizes a packet forwarding flow table to instruct an edge switch to direct user traffic to a specified serving node. The SDN controller may monitor load of a serving node in a service cluster, execute a load balancing function of the load balancer according to a load monitoring result, and select a target virtual machine. Using the SDN controller as a load balancer, a dynamic expansion capability of the SDN may be multiplexed at a control layer, and a network resource of the SDN network may be multiplexed at a network forwarding layer. Implementation complexity is low, and investment costs are low.
