4.1 GTP T#e&

GTP tunnels are used between two nodes communicatin over a GTP based interface- to separate traffic into differentcommunication flows.

GTP tunnel is identified in each node with a T2&8- an &P address and a 8P port number. The receivin end side of a

GTP tunnel locally assins the T2&8 value the transmittin side has to use. The T2&8 values are echaned betweentunnel endpoints usin GTP=1 or ",=MM2 messaes.

The criteria definin when the same or different GTP tunnels shall be used between the two nodes differs between thecontrol and the user plane- and also between interfaces.

7or the control plane- for each end=point of a GTP=1 tunnel;

= The T2&8=1 shall be uniAue per P8'=1onnection on GTP based "*b- ": and "C interfaces. The same tunnel

shall be shared for the control messaes related to all bearers associated to the P8'=1onnection. T2&8=1 onthe "*bI":I"C interface shall be released after all its associated 2P" bearers are deleted.

= There shall be only one pair of T2&8=1s per 2 on each of the "3- ",+ and the ",@ interfaces. The same tunnelshall be shared for the control messaes related to the same 2 operation. T2&8=1 on the "3I",+I",@interface shall be released after its associated 2 contet is removed or the 2 is detached.

= There shall be only one pair of T2&8=1 per 2 over the ",, and the "9 interfaces. The same tunnel shall be

shared for the control messaes related to the same 2 operation. T2&8=1 on the ",,I"9 interface shall bereleased after all its associated 2P" bearers are deleted.
