Abstract: The embodiment of the present application relates a user plane resource management method, a user plane network element, and a control plane network. The method carried out by a user plane network element includes: receiving a data transmission channel establishment request message sent by a control plane network element, where the data transmission channel establishment request message is used to instruct the user plane network element to establish a data transmission channel; establishing the data transmission channel based on current user plane resource status information, and assigning a channel identifier marking the data transmission channel; and sending, the channel identifier to the control plane network element.

Abstract: Example session management methods and apparatus are described. One example method includes allocating a first IP address and a first user plane network element to a terminal by a session management network element. The first user plane network element allocated to the terminal supports the first IP address.

Abstract: A communication method and a communications apparatus are disclosed. The method is performed by a control plane function entity and includes: obtaining a correspondence between address information of a user plane function entity and a user plane capability supported by the user plane function entity; receiving a request message from an application server, where the request message is used to request to establish a session for a first service and includes service information of the first service, and the service information includes at least one of broadcast area information and service type information; determining address information of a target user plane function entity based on the correspondence and the service information; and establishing a session connection to the target user plane function entity based on the address information.

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: A charging method, including sending, by a control plane gateway, a first charging trigger event to a user plane gateway, where the first charging trigger event triggering the user plane gateway to generate service usage information, generating, by the user plane gateway, the service usage information when the user plane gateway detects that the first charging trigger event occurs, sending, by the user plane gateway, the service usage information to the control plane gateway, generating, by the control plane gateway, a charging request according to the service usage information, and sending, by the control plane gateway, the charging request to a charging system. Offline charging during packet data network gateway (PGW) control and user (CU) separation is implemented.
