Abstract: A method for deleting GPRS tunnel protocol resources in a mobile communication system is provided to designate a TEID(Tunnel Endpoint Identification) assigned by an SGSN to request a PDP context to be deleted, and to set the designated TEID to a TEID of a GTP(GPRS Tunnel Protocol) header when a response message is transmitted, thereby retransmitting a delete PDP context response message only one time. A system sets a delete request message to be retransmitted 5 times(S101). An SGSN sets a TEID assigned from a GGSN, and transmits a delete PDP context request message to the GGSN(S102). The GGSN deletes a packet data protocol context for the TEID(S103), and transmits a delete PDP context response to the SGSN(S104). When the delete PDP context response is not received in the SGSN(S105), the SGSN decides whether a retransmission count value is smaller than the set frequency of retransmission(S106). If so, the SGSN increases the retransmission count value by 1(S107). If the retransmission count value is bigger than 0(S108), the SGSN retransmits the delete PDP context response message to the GGSN(S109).
