Abstract
Provided is an apparatus and method for transmitting user data by using a logical tunnel in an evolved UMTS network system. The method includes the steps of: a) assigning a tunnel Identifier (ID); b) creating a tunnel management table according to the tunnel ID; c) receiving downlink user data; d) creating a down-link protocol message corresponding to the down-link user data based on the tunnel ID; and e) transmitting the down-link protocol message.
Claims22
A method for transmitting user data in a mobile communication system, comprising the steps of:
- a) assigning a tunnel identifier (ID);
- b) creating a tunnel management table according to the tunnel ID;
- c) receiving downlink user data;
- d) creating a down-link protocol message corresponding to the down-link user data based on the tunnel ID;
- and
- e) transmitting the down-link protocol message.
A method for transmitting user data in a mobile communication system, comprising the steps of:
- a) assigning a tunnel ID;
- b) creating a tunnel management table according to the tunnel ID;
- c) receiving up-link user data from a base station;
- d) creating an up-link protocol message corresponding to the up-link user data based on the tunnel ID;
- and
- e) transmitting the up-link protocol message.
An apparatus for transmitting and receiving user data to and from a base station in a mobile communication system, wherein the apparatus includes a mobility management entity (MME) for managing and controlling mobility of a user equipment and a user plane entity (UPE) for transmitting user data, the apparatus comprising:
- a tunneling managing means for assigning a tunnel identifier (ID) corresponding to transmitted or received user data;
- and
- a base station interfacing means for transmitting and receiving a protocol message to and from the base station through a tunnel identified by the tunnel ID, wherein the tunneling managing means and the base station interfacing means are disposed in the user plane entity.
