Abstract
A method for receiving Logical Link Control (LLC) packet data of a mobile communications system comprising: detecting missed data using a frame number of received data; checking whether the number of the missed data having detected is less than a reference value; and ignoring the corresponding missed data when it is checked that the number of the missed data is less than the reference value, and transmitting currently-received data in real-time, whereby even if audio or real-time data partially contains an error and is missed in the air, the real-time transmission is ensured so as to allow a user to enjoy voice chatting or real-time videos more conveniently.
Claims19
An apparatus for receiving Logical Link Control packet data of a mobile communications system comprising:
- a Packet Data Protocol unit to set and release a session for a radio packet data communication;
- a controller to perform overall controlling operations of a system;
- a Logical Link Control unit to control a transmission speed of a frame unit packet data under the control of the controller;
- and
- a Frame Check Sequence unit to monitor an error of the frame data under the control of the controller, and to confirm and output an error occurrence.
An apparatus for receiving a Logical Link Control packet data of a mobile communications system comprising:
- a Serving GPRS Support Node to set a session by analyzing a call connection request signal, and to process a Logical Link Control processed packet data;
- a base station to connect to the Serving GPRS Support Node and thus receive packet data transmitted from a terminal in the set session;
- and
- a public network to connect to another communications network under the control of the Serving GPRS Support Node and thus to set a packet data transmission path.
A method for receiving Logical Link Control packet data of a mobile communications system comprising:
- a reception step of, for receiving packet data through a particular session, receiving and assigning frame unit packet data according to their sequence numbers;
- an error determination step of, when the frame unit packet data having received in the step contains an error, determining whether the error has a range less than a permitted range;
- and
- a format step of, when it is determined in the above step the range of the error is within the permitted range, repeatedly receiving and assigning frame unit packet data of the next sequence until every format unit frames are received.
A method for receiving Logical Link Control of a mobile communications system comprising:
- detecting missed data using a frame number of received data;
- checking whether the number of the missed data having detected is less than a reference value;
- and
- ignoring the corresponding missed data when the number of the missed data is less than the reference value, and transmitting currently-received data in real-time.
