The packet labeling type that step 101, basis receive, is diverted to subscriber signaling message on CPU and by user data message and is diverted to field programmable gate array (Field-ProgrammableGateArray is called for short FPGA);
Fig. 2 is the message format of the method process shown in Fig. 1, particularly, as shown in Figure 2, described subscriber signaling message at least comprises SCTP (StreamControlTransmissionProtocol, be called for short SCTP), GPRS Tunnel Protocol control (GPRSTunnellingProtocolControl, be called for short GTP-C) message, the S1AP field wherein comprised in SCTP is its application protocol, what carry in S1AP is NAS protocol massages, and GTP-C comprises subscriber signaling field.Described user data message at least comprises GPRS Tunnel Protocol user data (GPRSTunnellingProtocolUser is called for short GTP-U) message, and it comprises user data fields.
Wherein GTP-C exchanges as the signaling be responsible in EPC network between core node and the agreement of bearer management, realizes transmission and the QoS interaction mechanism of user's beared information, provides the bearing tunnel between network node to set up, revise and delete.S1-MME interface is the passage that eNodeB and MME is connected, and has been used for the control plane functions such as RAB control.
Described subscriber signaling message is diverted to each multinuclear thread and carries out packet parsing to obtain subscriber association information by step 103, described CPU, and described subscriber association information is sent to described FPGA;
During concrete parsing, the GTP-C in such as S11 interface can get the most information of user, but some information still needs to be obtained by the SCTP in S1-MME interface, as the acquisition of base station in the renewal process of base station number.Collector needs to resolve flow processs such as attachment, attachment removal, S1 release, service request, tracing section updating, GUTI code reassignment, base station switchings, relate to the parsing of NAS signaling in above-mentioned flow process resolving, the monitoring of note, telephony feature also needs to be undertaken by resolving NAS in addition.The deciphering of NAS needs the signaling resolution relating to S6a interface and S1-MME interface, and wherein S6a interface uses Diameter, comprises the authentication informations such as key in signaling.
