Abstract: Provided are a method and an apparatus for extracting QoS parameters in a mobile device. In the method, all packets received from a terminal device are monitored, and SIP packets are filtered. 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, QoS parameters are extracted from the SIP request packet or the SIP response packet. The extracted QoS parameters are incorporated into a wireless link data resource request and transmitted to a wireless network device. When a response to the wireless link data resource request is received, an uplink filter value for a new resource is extracted and added to a packet monitoring list.
