  • Patent number: 10893450
    Abstract: Disclosed in the present invention is a method for realizing continued transmission of user data during cross-cell handover of a user station. The method comprises: constructing a continuation guide table in an AP of a wireless network cell; when cross-cell handover of a user station occurs, configuring the continuation guide table in the AP; and when handover occurs, forwarding data being transmitted by the user station according to the continuation guide table. Further disclosed in the present invention is an AP of a wireless network cell. The AP is realized by constructing a continuation guide table in an existing AP. According to the present invention, uninterrupted transmission of data streams being transmitted when a user crosses a wireless network cell can be realized, thereby improving the user experience when the user surfs the internet using a wireless network.

  • Patent number: 9467537
    Abstract: A method and apparatus for transmitting and receiving data are disclosed. The method for transmitting data, comprising encapsulating one or multiple media access control protocol data units (MPDU) as a group media access control protocol data unit (G-MPDU) based on a length of the group media access control protocol data unit G-MPDU; fragmenting a current MPDU according to a residual length to obtain a fragmented MPDU when the residual length is insufficient to encapsulate the current MPDU; encapsulating the fragmented MPDU to the G-MPDU; and transmitting the encapsulated G-MPDU. The method ensures a high data transmission rate and does not wasting excess time to execute the fragmentation processing. The method also ensures a high resource utilization rate, utilizing fully the remaining length of the data unit.
