Method of controlling packet service setup and mobile communication system
View Patent ↗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.
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.
