Method and apparatus for setting up/releasing radio resource control connection between evolved node b and user equipment in communication system

A method for managing a connection at a user equipment (UE) in a communication system, the method comprising:

• identifying a type of traffic;
• transmitting, to a base station (BS), a connection request message for a connection between the BS and the UE, wherein the connection request message comprises information indicating the identified type of the traffic;
• and
• receiving, from the BS, a release request message for the connection when an inactivity timer, which is set corresponding to the identified type, is expired,
• wherein the type indicates first traffic triggered based on a user input or second traffic that occurs periodically.

A method for managing a connection at a base station (BS) in a communication system, the method comprising:

• receiving, from a user equipment (UE), a connection request message for a connection between the BS and the UE;
• obtaining information indicating a type of traffic in the UE;
• setting a value of an inactivity timer corresponding to the obtained type;
• and
• transmitting, to the UE, a release request message for the connection when the inactivity timer is expired,
• wherein the type indicates first traffic triggered based on a user input or second traffic that occurs periodically.

A user equipment (UE) for managing a connection in a communication system, the UE comprising:

• a controller configured to identify a type of traffic, set a value of an inactivity timer corresponding to the identified type, and start the inactivity timer;
• and
• a transceiver configured to transmit, to a radio network controller (RNC), a release request message for a connection between a base station (BS) and the UE when the inactivity timer is expired,
• wherein the type indicates first traffic triggered based on a user input or second traffic that occurs periodically.

A user equipment (UE) for managing a connection in a communication system, the UE comprising:

• a controller configured to identify a type of traffic;
• and
• a transceiver configured to transmit, to a base station (BS), a connection request message for a connection between the BS and the UE, wherein the connection request message comprises information indicating the identified type of the traffic, and receive, from the BS, a release request message for the connection when an inactivity timer, which is set corresponding to the identified type, is expired,
• wherein the type indicates a first traffic triggered based on a user input or a second traffic that occurs periodically.

A base station (BS) for managing a connection in a communication system, the BS comprising:

• a transceiver configured to receive, from a user equipment (UE), a connection request message for a connection between the BS and the UE;
• and
• a controller configured to obtain, information indicating a type of traffic in the UE, set a value of an inactivity timer corresponding to the obtained type, and control the transceiver to transmit, to the UE, a release request message for the connection when the inactivity timer is expired,
• wherein the type indicates one of a first traffic triggered based on a user input and a second traffic that occurs periodically.
