System (GSM, Global System of Mobile communication) and time-division code division synchronize multiple access
(TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) is
System.
Refering to Fig. 4, between mobile device 20 and application apparatus 10 hardware use USB (universal serial bus) (USB,
Universal Serial BUS) interface,
TFT matching feature realizes in data flow control module 210, and data flow control module 210 is responsible for number
Interface communication between applying according to path and protocol stack and agreement, it is achieved TFT to the coupling of business datum and
Corresponding EBI value is searched, and implements function as follows: data flow control module 210 receives USB interface and sends out
The uplink business data message sent, finds the external bus interface of correspondence by the coupling of TFT module 2101
(EBI, External Bus Interface), sends uplink business data message to RAB pipe
Reason (RABM, Radio Acess Bearer Mangement) module 220；RABM module 220 receives
Business datum message after the match is successful through TFT module 2101 in data flow control module 210,
And Data Radio Bearer (DRB, the Data of its correspondence is found according to the EBI value of business datum message distribution
Radio Bearer)。
For with the TFT module 2101 processing procedure to business data flow, one PF list of network configuration,
Each PF reference record is s_PF_param structure.Simultaneously defined in the TFT module of mobile device
TFT parameter list a_TFT_list, a_TFT_list are by s_PF_param and a dataflowId parameter
The array of composition.
It is as follows that this invention citing in LTE mobile device realizes flow process:
First step: from the business data flow of application apparatus 10, by USB interface, be sent to data
Flow control module 210, the stream identification of in the future self-application equipment 10 in data flow control module 210

Meet the dataflowId being assigned in p_servicePacketData by the dataflowId in a_TFT_list.
Further, at data stream header and the a_TFT_list of servicePacketData business datum
During s_PF_param in array compares, the most omparison purpose address and subnet mask, then
Relatively protocol number (IPv4)/next stem (IPv6), if not this content in packet header, is then packet
Type-iii form, according to the more remaining TOS of type of data packet III (IPv4)/type of service (IPv6)
With mask and stream label (IPv6)；If there is protocol number (IPv4)/next stem (IPv6), then reference source
The content of range of port number, without this content, is then type of data packet II form, packet class
Type II form, continues to compare IPSec SPI and TOS (IPv4)/type of service (IPv6) and mask；If
The content of source port number scope, then can only be type of data packet I, continue omparison purpose range of port number and
TOS (IPv4)/type of service (IPv6) and mask.Compare successively in confirmation p_servicePacketData
