1. A resource reservation method of a terminal, the method comprising:
- transmitting, from a terminal having negotiated communication condition with a counterpart terminal, an activate packet data protocol (PDP) context request message for reserving first resources according to the communication condition to a serving GPRS support node (SGSN);
receiving, from the SGSN, an activate PDP context reject message including information on a QoS level determined by the SGSN corresponding to the activate PDP context request message, when the first resources requested by the terminal cannot be allocated in a network;
determining whether to request second resources based on the QoS level indicating resource amount that can be allocated to the terminal in the network; and
requesting the second resources, when the terminal determines to request the second resources.

Abstract
The present invention relates to a resource reservation method and system for reserving resources in a mobile multimedia system, and the method of the present invention comprises: a resource request step in which a terminal, which has negotiated communication conditions with another terminal, transmits a PDP context activation request message for reserving resources according to the communication conditions to a serving GPRS support node (SGSN); and a response step in which the SGSN transmits a response message including information on a determined QoS level to the terminal.

3. A terminal for reserving resources in a mobile multimedia system, the terminal comprising:
-
a transceiver configured to transmit and receive a signal; and a controller configured to control; transmitting, to a serving GPRS support node (SGSN), an activate packet data protocol (PDP) context request message for reserving first resources according to a communication condition of the terminal, receiving, from the SGSN, an activate PDP context reject message including information on a QoS level determined by the SGSN corresponding to the activate PDP context request message, when the first resources requested by the terminal cannot be allocated in a network, determining whether to request second resources based on the QoS level indicating resource amount that can be allocated to the terminal in the network, and requesting the second resources, when the terminal determines to request the second resources. - View Dependent Claims (4)

5. A resource reservation method of a serving GPRS support node (SGSN), the method comprising:
-
receiving, from a terminal having negotiated communication condition with a counterpart terminal, an activate packet data protocol (PDP) context request message for reserving first resources according to the communication condition; and transmitting, to the terminal, an activate PDP context reject message including information on a QoS level determined by the SGSN corresponding to the activate PDP context request message, when the first resources requested by the terminal cannot be allocated in a network, wherein it is determined by the terminal whether to request second resources based on the QoS level indicating resource amount that can be allocated to the terminal in the network, and wherein the second resources are requested when the terminal determines to request the second resources. - View Dependent Claims (6, 7, 8)
