The present invention takes multithreaded architecture to realize cooperation relation between each module of this signalling tester, Figure 3 shows that the relation between each thread in the modular architecture of the present invention, main thread comprises the data acquisition thread, just analyzes thread, and data deposit thread and result show thread.Having taked this multithreaded architecture is the performance bottleneck problem that system may occur when reducing the message real-time statistic analysis to greatest extent.The data acquisition thread is responsible for receiving data from hardware, for packet loss not when the two-forty, this thread is set to the thread of a high priority, the effect of this thread is to receive signalling message data from hardware, the message data that receives is stored in the big buffering area of message with certain form, the organizational form of message data is seen Fig. 4 in the big buffering area of message, the bit that this field of numeral among Fig. 4 is shared, wherein message length field represents that the SD-PDU data division adds the length of first cell head, and unit is a byte; Channel number refers to message is from which passage; Time tag represents to receive the time of message, is accurate to millisecond; The SD-PDU data division is represented the physical signaling message data received, storage be byte number.

Just analyze the responsible original signaling message that receives is decoded of thread and also decoded result is left in the first decoded result buffering area, just analyze the on-the-spot part that needs real-time decoding of extracting of thread, be shown to the user.Be illustrated in figure 5 as decoded data format just, just solve message numbering, offset address, time tag, VPI, VCI, AAL type, CID, L3 protocol class, L3 type of message, L4 protocol class, L4 type of message, feature field in the original signaling message, deposit decoded result buffering area just in, the byte number that this field of numeral among the figure is shared, the wherein regulation of feature field and Layer3, transport network layer L3, Layer4, the regulation of wireless network layer L4 is as follows:

The AAL type---the indication ATM cell is at the signaling bear adapting layer types of transport network layer;

L3 protocol class/L3 type of message---indication information element carries out dismounting through transport network layer by which kind of protocol format, for the Iu-CS protocol model, may be Service Specific Connection Oriented Protocol SSCOP (Service Specific Connection Oriented Protocol), service specific coordination function-SSCF (Service specific co-ordination function), message transfer part (broadband)-MTP3b (Message transfer part (broadband)), SCCP-SCCP (Signalling Connection Control Part), what correspondingly, the L3 message type field promptly showed is SCCP user's a certain concrete message; Also may be access link control applying portion SSCOP-SSCF-MTP3b-ALCAP (Access Link Control Application Part), then the L3 message type field shows be exactly type of message in last agreement; If signaling is through the AAL2 carrying, and pass through the user plane of this layer, the L3 protocol class then may be RRC or other Iu interface functions, and the L3 type of message promptly refers to the core message of finishing corresponding function; For the Iub protocol model, may be SSCOP (or-SSCF), correspondingly, what the L3 message type field promptly showed is the type of the protocol Data Unit in SSCOP (or SCCF) agreement; Also may be SSCOP-SSCF-ALCAP, what then the L3 message type field promptly showed be the type or the type of message of the protocol Data Unit in the superiors' agreement; For user plane, with Iub roughly the same; For the Iur protocol model, protocol class is SSCOP-SSCF-MTP3b-SCCP and SSCOP-SSCF-MTP3b-ALCAP, and situation and Iub are roughly the same; If signaling is earlier according to IP SCTP IP-SCTP (Stream Control Transmission Protocol), SS7 MTP3-User Adaptation Layer-M3UA (SS7 MTP3-User Adaptation Layer), SCCP that then walks respectively and STC-ALCAP, then separately expression of L3 type of message; Iur at the signaling tendency of transmission network user plane and Iu roughly the same.Protocol class/type of message when L4 protocol class/L4 type of message---indication information element encapsulates through wireless network layer.For the Iu-CS protocol model, then be wireless access network application protocol RANAP or Iu user plane Frame Protocol Iu UP, the L4 type of message promptly refers to the core message of finishing corresponding function; For the Iub protocol model, then be Node B application protocol NBAP or Iub user plane Frame Protocol IubUP, the L4 type of message promptly refers to the core message of finishing corresponding function; For the Iur protocol model, protocol class then is Radio Network Subsystem Application Part RNSAP (Radio Network SubsystemApplication Part), or Iur UP (Iur user plane Frame Protocol), the L4 type of message promptly is a core message of finishing this layer corresponding function;

Feature field---according to the decoding actual conditions, to the extraction of the field that the user was concerned about in some core messages, as address (or number) information, operating instruction (upgrading) etc., as then not filling a vacancy as route application, authentication, position.

Corresponding detailed decoding output format, as shown in Figure 6, total principle is hierarchical decoding, refinement gradually, asks and abandon little, dislocation demonstration greatly.

Hierarchical decoding: according to the order and the level of data encapsulation, successively decode, and represent hierarchical relationship with all kinds of titles respectively by the level of ATM Adaptation Layer, transport network layer, wireless network layer.

Refinement successively: in each layer, divide, each byte and even bit that some is special are made an explanation according to different protocol class and field.

Ask abandon greatly little: can't handle or data that intractability is excessive for running in the decode procedure, can put earlier on one side, and untreated data are shown handle (as " can't recognition data " among Fig. 6).

Dislocation shows: allow the sense that relatively has levels of detailed decoding and displaying, be convenient to the user and find the data of being concerned about fast.

The interface display thread is responsible for notifying main program to show the content of decoding just, and the interface display thread at first judges currently have that do not have can content displayed, if having, just to the message of main program transmission interface display.

Deposit thread in backstage is responsible for that the origination message storage in the big buffering area is used to reduce memory consumption on disk message on the backstage, also can do off-line analysis according to these data in the future.Because disk operating is with respect to internal memory operation, more time-consuming, overall performance for software, can take background thread, finish the deposit of signalling message data on the backstage, because Signaling Analyzer will guarantee continuous on-the-spot test, the signalling message data that is collected may be very many, if all be placed in the internal memory, the performance of system there is certain influence.

Owing to take multithreading, just certainly exist the problem of thread synchronization, the problem that thread synchronization will solve is exactly when each thread is scheduled and when hangs up.A) when the data acquisition thread is write message data in the big buffering area of storing message data, just analyze thread and also carrying out the first decoding of message data, at this moment, the message that is being written into may be also imperfect, should not participate in decoding, the message of decoding must be a complete message, when the big buffering area of message does not also have the full message of decoding, just should activate decoding thread just; When not having a full message in the big buffering area of message, the thread of just decoding should be hung up.

B) decoded thread originally when decoded result is put into just the decoded result buffering area, the interface display thread is also in the demonstration of carrying out decoded result, and at this moment incomplete result is not revealed.

C) deposit thread in backstage should guarantee that every message of storing all is complete message when message data is stored into disk, does not have the thread of deposit not covered by new information simultaneously, and for good extensibility, source codec and interface display are separately.Existing Signaling Analyzer, source codec and last the demonstration are closely-coupled, in decode procedure, directly decoded results is outputed to display interface, that is to say if revise software interface, must in the dynamic link library of decoder module, revise, this close coupling is unfavorable for the maintenance and the upgrading of software, in design of the present invention, take the distinct mode of source codec and procedure for displaying, and, divide and the minimizing complexity for the ease of function, each functional module mainly adopts the form of dynamic link library, and the function of each dynamic link library is separate, has reduced dependence each other.

The Signaling Analyzer of the present invention design according to the interface characteristic of TD-SCDMA system, is resolved three protocol stacks of the interface, and extracting has related parameter, is convenient to the mobile radio communication attendant and solves practical problem in network operation, the optimization work.And, taked a kind of multithreaded architecture to coordinate cooperation relation between each module of this Signaling Analyzer, the frame mode of each intermodule loose coupling is with good expansibility this Signaling Analyzer.
