    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: Embodiments of this application disclose a charging management method, a user plane function entity, and a control plane function entity. The method includes: receiving, by a UP, a first usage reporting rule (URR) and a second URR sent by a CP, where the first URR is correlated with the second URR; when usage information on the UP reaches a threshold of the first URR, obtaining, by the UP, usage information corresponding to the first URR and usage information corresponding to a third URR correlated with the first URR; and sending, by the UP to the CP, the usage information corresponding to the first URR and the usage information corresponding to the third URR, so that the CP generates a charging data record based on the usage information corresponding to the first URR and the usage information corresponding to the third URR.

    Abstract: Embodiments of the invention relate to communications field, in particular, to a downlink data notification message sending method, and apparatus. The method is: receiving, a delay instruction sent by a mobility management network element, which is used to instruct a control plane network element to delay sending a DDN message; receiving, an event report message sent by a user plane network element, where the event report message includes a reported event, and the reported event is used to notify the control plane network element that a downlink data packet sent to UE matches no bearer; determining, that the UE is registered in the mobility management network element; and if the control plane network element has not received, within a first time period, routing information of a base station, sending, the DDN message to the mobility management network element when the first time period expires.

    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: A local area network communication method, a device, and a system, to implement private communication across session management network elements for a local area network service. The method includes: determining, based on indication information of a local area network, first path information associated with a first address, where the first path information indicates routing data whose destination address is the first address to a first user plane network element, and where the first user plane network element provides access to the local area network for a terminal corresponding to the first address; and sending a first message to a second session management network element, for configuring a first routing rule on the second user plane network element, where the first routing rule includes the indication information of the local area network, the first address, and the first path information.
