Abstract
Provided are a method and device that identify characteristics of data to be sent by a user equipment and send small-sized data via a control message. The data transmission method for the user equipment may include: generating IP data; determining whether the IP data corresponds to small data that has a size less than or equal to a preset reference size or matches identification information of a preset service; and transmitting the IP data through a connection management (CM) layer to the network by use of a control message.
Claims16
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.
A terminal supporting data transmission, comprising:
- a transceiver configured to transmit and receive signals to and from a base station;
- and
- a controller configured to:
- generate first internet protocol (IP) data for a first packet data network (PDN) connection installed with a small data packet filter,
- determine 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,
- control the transceiver to transmit, 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 the base station by using a control message,
- determine, 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,
- transmit the first IP data by using a radio bearer, in case that the first IP data matches the at least one other packet filter,
- drop the first IP data in case that the first IP data does not match the at least one other packet filter,
- generate a second IP data for a second PDN connection without the small data packet filter, and
- control the transceiver to transmit the second IP data to the base station by using a radio bearer.
