NETWORK NODE AND METHOD OF CONFIGURING PDCP FOR WIRELESS COMMUNICATION DEVICE Russian patent published in 2020 - IPC H04W48/18 H04W92/24 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to the wireless communication network. Method is carried out by a network node for configuring a packet data convergence protocol (PDCP) for a wireless communication device in a communication network. Communication network comprises a first-type core network and a second type core network. Network node decides whether a network node is a primary node or a secondary node for a wireless communication device. When the network node is the main node, it configures the PDCP for the wireless communication device based on which of the first and second types of the core network the wireless communication device is connected to. When a network node is a secondary node, it configures the PDCP for the wireless communication device based on any one or more of which: to which of the first and second types of the main node the network node is connected and to which of the first and second types of the core network the wireless communication device is connected. First type and the second type are related to different generations of telecommunication networks.

EFFECT: technical result consists in providing better performance for end user, as well as saving costs for network operator.
