Patent ID: 8605612

Claim:
A method for extracting Quality of Service (QoS) parameters in a mobile device, the method comprising: monitoring all packets received from a terminal device to filter Session Initiation Protocol (SIP) packets; when a real-time service application is executed on the terminal device, and an SIP request packet or an SIP response packet is filtered and input, extracting QoS parameters from the SIP request packet or the SIP response packet; incorporating the extracted QoS parameters into a wireless link data resource request and transmitting the wireless link data resource request to a wireless network device; when a response to the wireless link data resource request is received, extracting an uplink filter value for a new resource from the response and adding the uplink filter value to a packet monitoring list; and discriminating data of the real-time service application from all data received from the terminal device using the uplink filter value and transmitting the discriminated data using the new resource.
