METHOD AND DEVICE FOR ROUTE PROCESSING AND TERMINAL DEVICE Russian patent published in 2019 - IPC H04W36/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. User device determines, based on information on connection parameters corresponding to at least one existing PDN network connection for packet data transmission, whether the target PDN network connection satisfies the target connection condition exists in the set of at least one existing PDN network connection. If the target network connection PDN satisfying the specified target connection condition exists, the user device transmits the service data packet using the target network connection PDN. If the target network connection PDN satisfying the specified target connection condition does not exist, the user device initiates the PDN target network connection setup for transmitting the service data packet using the established PDN target connection.

EFFECT: providing a PDN connection, which satisfies target connection capabilities for optimizing a service transmission path and high quality of service transmissions.
