The invention provides a mobility management method among wireless access networks, a core network device and a base station. When inter-RAT movement of a terminal in an inactive state occurs, the user context information of the terminal when the terminal is in the inactive state in the NR system is still kept, and the user context information is deleted until certain conditions are met. The inter-RAT mobility management of a terminal in an inactive state can be realized, and inter-RAT mobility problem is solved, and the terminal can work normally.

The embodiment of the invention discloses a mobile management method and device, which relate to the technical field of mobile communication and are invented for solving the problem that the mobile management of a mobile management system framework based on user identity in the prior art can not be carried out when user positions are changed.

This invention is benefit to independent running or cruise with each other for different communication systems.

The invention discloses an ad-hoc network mobile access switching method based on blockchain security attributes, and the method comprises the steps: carrying out the corresponding updating of an unmanned plane cluster network through a period of a route learning package under the condition of link switching when the position change of an unmanned plane node causes the network topology change; forthe condition that the ground terminal moves, ensuring the communication stability by dynamically binding the unmanned aerial vehicle node with the ground terminal. Through adoption of the method, mobility management of the unmanned aerial vehicle cluster network is realized, so that seamless communication between the ground terminal and the unmanned aerial vehicle cluster network is ensured.

The invention relates to an implementation method and system for building direct tunnels as well as network elements. In the scene that a terminal moves, the method comprises the steps that a target radio network controller (RNC) sends a downlink tunnel address allocated to the terminal by the target RNC to a new gateway general packet radio service (GPRS) support node (GGSN) via a new serving GPRS support node (SGSN); and the new GGSN allocates the uplink tunnel address to the terminal and sends the uplink tunnel address to the target RNC via the new SGSN, wherein the two steps are in no particular order. By adopting the implementation method and the system as well as the network elements, the problem of alternative route is solved on the basis of implementing the direct tunnel.

The invention discloses a data stream transmission method, a data stream transmission device and a data stream transmission system. The data stream transmission method includes the steps: firstly, identifying a multi-homing host in a network, determining data stream requesting redirection and transmitting a updated address of the multi-homing host used by the data stream; secondly, sending updated address information to a correspondent node corresponding to the data stream, wherein the updated address information carries a corresponding relation of a stream identifier of the data stream to the updated address; and thirdly, transmitting the data stream by the aid of the updated address and the correspondent node after successful response returned by the correspondent node to address updating is received. By the aid of the method, mobile management facing the data stream in the identification network can be realized.
