  • Patent number: 9801108
    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.

  • Patent number: 9686231
    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.
