Abstract: An Internet Protocol (IP) address allocation method and a device to resolve a technical problem that an IP address conflict occurs when a control plane device and a user plane device allocate an IP address for one user equipment (UE) at the same time. When receiving a session establishment request message, a control plane network device may determine whether a first user plane network device is capable of allocating an IP address for a terminal device. If the first user plane network device is capable of allocating the IP address for the terminal device, the control plane network device may send an address allocation indication to the first user plane network device.

Abstract: Gateway configuration methods and devices that resolve problems of a relatively heavy configuration workload, update inflexibility, and low configuration efficiency that exist when an operation and maintenance (OM) entity is used to uniformly configure gateways in an LTE system. The method includes: configuring, by a control plane gateway, a parameter for a user plane gateway, and sending, by the control plane gateway, a configuration message to the user plane gateway, where the configuration message carries the configuration parameter configured by the control plane gateway for the user plane gateway. The control plane gateway configures the parameter for the user plane gateway, so that the control plane gateway implements configuration of the user plane gateway, and configuration flexibility and configuration efficiency are improved.

Abstract: This application discloses a clock status synchronization method and a communication apparatus. In the method, a first access network device determines a clock status of the first access network device, and sends a clock status message to a first network device or a target terminal. The first network device and/or the target terminal sends a time provision request to a second network device based on the clock status message, to request to obtain an access network device for providing a time provision service for the first network device and/or the target terminal. The second network device determines the access network device for providing the time provision service for the first network device and/or the target terminal, and sends time provision indication information to the determined access network device, to indicate the access network device to provide the time provision service for the first network device and/or the target terminal.
