Abstract: The application provides a method for providing an internet protocol (IP) address to a terminal device by a network node. The network node receives, from the terminal device, a request for acquiring an IP address in a packet data network (PDN) connection. The request includes a requested IP address version. The network node allocates an IP address for the terminal device in response to the request, and sends the address allocated by the network node and a PDN address capability to the terminal device. The PDN address capability is determined by the network node according to the request, and the PDN address capability indicates that only an assigned version of the allocated IP address is allowed by the network node in the PDN connection.

Abstract: A method for acquiring information includes: receiving an Internet Protocol (IP) address acquisition request or Packet Data Network (PDN) address allocation information sent by User Equipment (UE); determining a PDN address capability according to the IP address acquisition request or the PDN address allocation information; and sending the determined PDN address capability to the UE. An UE and network equipment are also provided. The PDN address capability is determined by the network and is sent to the UE, so as to indicate to the UE the IP address information that may be acquired in a current PDN connection, such that when the network cannot provide an IP address for the UE any more, the UE is prevented from acquiring other IP addresses in other manners, avoiding service abnormality.

Abstract: Embodiments of the present application provide a method for a handover without a default bearer. A first network device sends a relocation request to a second network device. The second network device establishes a connection to a third network device indicated by the relocation request, and sends a response to the first network device and indicates that data is to be sent by using a signaling plane. Then the first network device instructs a source network device to forward the data to a target network device according to a forwarding mode indicated by a handover command. Alternatively, after the second network device establishes the connection to the third network device indicated by the relocation request, the third network device caches data, and after a handover of user equipment is completed, the third network device sends the cached data to the second network device.

Abstract: Embodiments of the present invention provide a data transmission method, device, and system. A terminal device determines whether a data volume of uplink data to be sent is less than a preset data volume threshold. If the data volume of the uplink data to be sent is less than the preset data volume threshold, the terminal device establishes an RRC connection to a base station and sends an RRC connection completion message that carries the uplink data to the base station, so that the base station sends the uplink data to an MME by using a signaling message between the base station and the MME. The MME further sends the uplink data to a corresponding application server by using a signaling message between the MME and a P-CSCF.

Abstract: One example method includes receiving, by a first mobility management network element, a first cell identifier and a network identifier from a first network element, where the network identifier includes an identifier of a first private network and an identifier of a second private network. The first mobility management network element can then obtain information about a second network element based on the first cell identifier and the network identifier, where the first network element serves a terminal device in the first private network, and where the second network element serves the terminal device in the second private network. The first mobility management network element can then send the first cell identifier and the network identifier to the second network element indicated by the information about the second network element, where the first cell identifier and the network identifier are used to obtain downlink routing information.

Abstract: An intent maintenance method and an apparatus provides a status awareness module that obtains a first duration corresponding to an intent. The status awareness module receives from a policy management module first information indicating that a first executable command corresponding to the intent starts to be executed. The status awareness module determines second duration when execution duration of the first executable command reaches the first duration and an object of the intent is not achieved, the second duration being greater than the first duration, and sends second information to the policy management module.

Abstract: Traffic data is divided into data streams corresponding to workloads, and the data streams are multiplexed onto slice segments based on a multiplexing requirement or rule. Each slice segment is a physical or virtual processing element in a wireless network supporting network slicing. In one example, the data streams are multiplexed onto the slice segments such that data streams having different utility definitions are assigned to different slice segments. In another example, the data streams are multiplexed onto the slice segments such that workloads in the same cluster partitioned in a T-dimensional vector space are assigned to different slice segments.
