A communication method comprises that if a policy control device does not support setup of an Internet Protocol (IP) multimedia subsystem (IMS) default bearer during setup of an IMS default bearer for a terminal, the control plane gateway sends second indication information to a user plane gateway, where the second indication information indicates the control plane gateway bypasses the policy control device. When the user plane gateway receives an IMS session request from the terminal and determines that the control plane gateway bypasses the policy control device, the user plane gateway sends first indication information to the control plane gateway, and the first indication information indicates the control plane gateway to send, to the policy control device, a first request to request to establish a mapping relationship between the terminal and the control plane gateway such that an IMS session can be set up between terminals.

Communication method and apparatus

A virtual network function (VNF) deployment method and apparatus is provided. The method comprises: obtaining a virtual network function descriptor (VNFD), where the VNFD includes input parameter information, input adaptation information, and VNF descriptor information; the input parameter information includes N pieces of management unit information, each piece of management unit information is used to describe an attribute of a management unit; the input adaptation information is used to indicate a mapping relationship between the management unit and a logical management unit; mapping management units corresponding to the N management unit identifiers to the N logical management units based on the input adaptation information; and creating the VNF on the N logical management units based on the VNF descriptor information. The embodiments of this application are applicable to VNF deployment process.

Virtual network function VNF deployment method and apparatus

A method, a related apparatus, and a system for recovering a called service of a terminal are provided. The method includes: when a called request of a user terminal is received, querying an initial proxy-call session control function (P-CSCF) entity with which the user terminal currently registers; if it is detected that the initial P-CSCF is faulty, selecting an available P-CSCF and sending, to the available P-CSCF, a notification message that carries a redundancy identifier, where the redundancy identifier is used to instruct the available P-CSCF to trigger the user terminal to re-register with the P-CSCF; and when a registration complete message sent by the P-CSCF with which the user terminal re-registers is received, delivering the called request to the re-registered P-CSCF to bear a called service of the user terminal.

Embodiments of the present invention disclose a voice service handover method and a device, and relate to the communications field, so as to resolve a problem that reliability of a voice service of UE is reduced due to an exception that occurs on a network side of an LTE network. A specific solution is as follows: An MME determines that an exception occurs on a network side of an LTE network, where a voice bearer of target UE is established on the network side of the LTE network; and the MME sends, to an eNodeB, an SRVCC handover request message that carries an identifier of the target UE, so that the eNodeB hands over a voice service of the target UE from the LTE network to a CS network. The present invention is applied in a voice service handover process.

This application provides a troubleshooting method and apparatus. The troubleshooting method includes obtaining key performance indicator (KPI) information of each service processor in a monitored network element; determining a faulty object according to the KPI information; determining a troubleshooting policy according to the faulty object; and sending the troubleshooting policy to a management unit in a network function virtualization (NFV) system, so that the management unit uses the troubleshooting policy to perform troubleshooting. Using the method or apparatus in this application, a problem of relatively low precision in fault locating according to a heartbeat message of a network element can be resolved.

Troubleshooting method and apparatus using key performance indicator information

A traffic control method and apparatus is presented, where the method includes determining, by a back-end network element according to a type of a received service message, a priority of the service message and a resource that needs to be consumed for processing the service message; obtaining, according to the priority of the service message and usage of the resource, a quantity or an adjustment quantity of service messages of a different type to be received in a current period; and sending the quantity or the adjustment quantity of the service messages of the different type to be received in the current period to a front-end network element.
