Claim of US Patent No. 10,485,033

1. A method of data transmission by a terminal, the method comprising:generating first internet protocol (IP) data for a first packet data network (PDN) connection installed with a small data packet filter;
determining whether the first IP data satisfies a preset criterion of the small data packet filter, by determining whether a size of the first IP data is less than or equal to a predetermined size and the first IP data matches identification information of a preset service;
transmitting, in case that the first IP data satisfies the preset criterion of the small data packet filter, the first IP data through a connection management layer to a base station by using a control message;
determining, in case that the first IP does not satisfy the preset criterion of the small data packet filter, whether the first IP data matches at least one other packet filter of a precedence lower than the small data packet filter;
transmitting the first IP data by using a radio bearer, in case that the first IP data matches the at least one other packet filter;
dropping the first IP data in case that the first IP data does not match the at least one other packet filter;
generating a second IP data for a second PDN connection without the small data packet filter; and
transmitting the second IP data to the base station by using a radio bearer.
