Abstract

Disclosed are a method of controlling packet service setup and a mobile communication system. The method includes the steps of: transmitting a packet service request message containing a requested QoS to a packet service node by a mobile communication terminal; transmitting to the mobile communication terminal a packet service request response message including an assigned QoS determined in consideration of the requested QoS and network resources contained in the message received by the packet service node; comparing one or more parameter values among parameters contained in the assigned QoS contained in the packet service request response message from a mobile communication network with corresponding one or more parameter values among parameters contained in the QoS requested by the mobile communication terminal; and transmitting a packet service cancel request message if a difference between the parameter values is greater than or equal to a preset value.

Claims

1. A method of controlling packet service setup by quality of service (QoS) in a mobile communication terminal, comprising:

transmitting to a Serving GPRS Support Node (SGSN) a packet data protocol context activation request message that is required for packet exchange path setup;

receiving a packet data protocol context activation accept message from the SGSN;

comparing a transmission speed, which is contained in an assigned QoS parameter of information contained in the packet data protocol context activation accept message, with a preset transmission speed; and

transmitting a packet data protocol context activation cancel message to the SGSN to cancel the packet exchange path setup by a user'"'"'s command, if the transmission speed contained in the assigned QoS parameter is lower than the preset transmission speed.

2. The method of claim 1, wherein the transmission speed is a downlink transmission speed.

3. A method of controlling packet service setup by quality of service (QoS) in a mobile communication terminal, comprising:

transmitting to a Serving GPRS Support Node (SGSN) a packet data protocol context activation request message that is required for packet exchange path setup;

receiving a packet data protocol context activation accept message from the SGSN;

displaying a transmission speed that is contained in an assigned QoS parameter of information contained in the packet data protocol context activation accept message; and

transmitting a packet data protocol context activation cancel message to the SGSN to cancel the packet exchange path setup by a user'"'"'s command.

4. The method of claim 3, wherein the transmission speed is a downlink transmission speed.

5. A mobile communication system comprising:

a packet service node; and

at least one mobile communication terminal;

wherein the packet service node receives a packet service request message from the mobile communication terminal, determines a quality of service (QoS) to be assigned taking account of available network resources and a requested QoS contained in the packet service request message, and transmits to the mobile communication terminal a packet service request response message containing the assigned QOS; and

wherein the mobile communication terminal transmits a packet service request message to the packet service node, receives the packet service request response message from the packet service node, compares a transmission speed parameter of QoS parameters contained in the packet service request response message with a preset transmission speed, and transmits a packet service cancel request message to the packet service node to cancel the packet exchange path setup by a user'"'"'s command, if the transmission speed contained in the packet service request response message is lower than the preset transmission speed.

6. The mobile communication system of claim 5, wherein the packet service node is a Serving GPRS Support Node (SGSN).

7. The mobile communication system of claim 6, wherein the packet service request message is a packet data protocol context activation request message.

8. The mobile communication system of claim 7, wherein the packet service request response message is a packet data protocol context activation accept message.

9. The mobile communication system of claim 8, wherein the packet service cancel request message is a packet data protocol context activation cancel message.
