Description
Technical field
The present invention relates to mobile communication system, referring more particularly to a kind of protocol stack simulator for developing mobile communication system man-machine interface (being called for short, MMI) software.
Background technology
In mobile communication system, MMI provides human-computer interaction interface, is responsible for user and lower-layer protocols stack software interactive, accepts user's input, expresses the Output rusults of protocol stack sofeware.
And protocol stack, be also called protocol groups or agreement family, refer to a series of relevant communication protocol, it operates together as a group, communicates in the design standard of physical layer by this protocol stack.
Most protocol stack is made up of physical layer, data link layer (being also called Access Layer), network layer (being also called Non-Access Stratum) and application adaptation layer, it adopts hierarchical architecture design, and every one deck performs a certain particular task and has function isolation to a certain degree.Only have physical layer just to need to understand bottom hardware details in protocol stack, all the other parts all with hardware independent, their by general-purpose interface downwards and physical layer of specific hardware link up, upwards linked up by application adaptation layer and application layer.And every one deck only communicates with adjacent layer, the function needed for it is all provided by adjacent layer, namely without the need to paying close attention to the function of other layers.Comprise the mobile communication terminal software configuration of MMI and protocol stack as shown in Figure 1.
Generalized Communication Interface between MMI and protocol stack is ATTENTION instruction (being called for short, AT instruction).AT instruction can be divided into local service and the large class of Network two by processing region: 1) local service, refers to not need to carry out alternately with network, and be directly responsible for the AT instruction processing and respond by application adaptation layer, most of AT instruction belongs to local service; 2) Network, refers to be initiated or need AT instruction relevant to the mobile communication business of network interaction by network, and these AT instructions need the function service module in application adaptation layer to communicate with Non-Access Stratum.
In the protocol stack design of mobile communication terminal, the message being initiated to be delivered to lower floor is called request (Request) message, and lower floor is called response (Response) message to the message that this request message is replied by upper strata; Meanwhile, the message being initiated to be delivered to upper strata by lower floor is called instruction (Indication) message, if upper strata needs to reply Indication message, then claims to reply message for response (Response) message.
When MMI initiates Network AT instruction, send a request message to Non-Access Stratum by the function service module in application adaptation layer, then after the information interaction completing with network by Non-Access Stratum and lower floor thereof, request message is responded; When network initiates Network, send Indication message by Non-Access Stratum and show network operation to each function service module, if desired Indication message is replied, then by function service module, Indication message is responded.
In protocol stack, application adaptation layer is decoded to the AT instruction that MMI issues, and sends corresponding request message by decoded result and process to function service module, encodes, and this response is sent to MMI module to the response of function service module.When AT instruction is correlated with in process Network, corresponding function service module is needed to carry out according to the interface and flow process and Non-Access Stratum with Non-Access Stratum mutual with the process of finishing service function; Non-Access Stratum is to a certain extent independent of Access Layer agreement, and be responsible for the transmission of information between handle mobile terminal and core net, the content of transmission can be user profile or control information, and the transmission of non-access layer information will based on the Access Layer agreement of bottom; Access Layer agreement refers to the agreement that wireless access network adopts, and for mobile terminal, it mainly refers to Radio interface protocols, and Access Layer provides concrete wireless technology access.Finally communicate in the design standard of physical layer by this protocol stack.
Following a few class business interface is had: a, Call-Control1 interface between Non-Access Stratum and application adaptation layer; B, short message interface; C, the network information arrange and report interface; D, supplementary service control interface; E, data service control interface.All kinds of business defines concrete interface message data structure by its Service Period, and interface message is made up of message header and message body: message header comprises type of message, and each interface message identifies and differentiated service type and Service Period with unique type of message.
Parameter in the message data of Non-Access Stratum can be divided into two classes usually, and a class is only in the content of parameter that function service inside modules uses, and do not affect operation flow and AT response results, these parameters can use the default value pre-set, and are called preset parameter; Another kind of is the parameter that will affect operation flow, AT response results and need to be supplied to network, is called running parameter.The value of running parameter is obtained by two kinds of modes: the instruction of a, network or response message obtain; B, directly obtained by request message content or obtained according to business flow processing by key control parameter wherein.Message constructing is that running parameter is constructed complete message according to interface message structure together with preset parameter.
In the software development process of mobile terminal; in order to improve exploitation and debugging efficiency; other modules relevant to these modules are developed and debugged to the function that simulator usually can be adopted to carry out the certain module of simulating mobile terminal; such as; developed by MMI simulator and debug protocol stack software, or develop and debug MMI software etc. by protocol stack simulator.
The protocol stack simulator structure of prior art as shown in Figure 2, comprising:
1) communication adaptation unit: according to providing corresponding communication adaptation function to the communication mode between MMI software, the AT instruction issued by MMI is sent to AT instruction codec unit, and the response of AT instruction codec unit or the message that reports are sent to MMI.
2) AT instruction codec unit, its function comprises, a, the AT instruction that MMI issues to be decoded, from default ResponseAPDU, corresponding response data is selected according to decoded result and matching principle, and these data are encoded to the results messages needing to return by predetermined describing mode, then pass through communication adaptation unit by transmission of messages to MMI; B, the network event triggered according to control inerface to report unit from network event by pre-defined rule and select corresponding reported data, and be converted to the instruction of specific AT message, then by communication adaptation unit by transmission of messages to MMI.
3) ResponseAPDU is preset: store in advance according to the matching principle of the requirement definition good related service AT order of MMI software and the describing mode returned results and response data script.
4) network event reports unit: store and construct the network event reported data script that may need according to the demand of MMI software.
5) SIM card unit is simulated: the file content in SIM card specification is described, for default ResponseAPDU provides the simulation SIM card file content of needs by the mode of setting.
6) control inerface unit: with the interactive interface of user, the content of display reporting information, provides the network information arrange and control with the operation of network interaction business, to reach the function of testing each network related service of MMI software.Network-related functions is mainly: a, Call-Control1, comprises call state and parameter that display MMI initiates, and provides and hang up or the operating function of call accepted, provides simultaneously and makes a call to test called function at MMI; The relevant information display of b, supplementary service, comprises display call forwarding, call blocking, the state of Call Waiting and line identification and parameter; C, short message, comprise the content of short message that sends MMI and parameter shows, and beam back short message or status report is tested to MMI; The display of d, the network information and setting, comprise the network selection result that display is current, provide the setting to field intensity, network state, access technology, network selection.
From the above mentioned, existing protocol stack simulator in advance according to the matching principle of the requirement definition good related service AT instruction of MMI software and the describing mode that returns results, then must construct the response data script that may need to the AT needed.Because the AT instruction of consensus standard definition has more than 100, in addition the different parameters that each AT instruction itself has is arranged, the diversity making MMI issue AT is unable to estimate, default response data is very limited in contrast, therefore, the protocol stack functional simulation that can provide of existing protocol stack simulator is very limited; And this pattern has only focused on the design of response data, less to the relevance operational processes between each AT or business, protocol stack Environmental Support required when MMI well can not be provided to develop or debug, simultaneously, this preset data that existing protocol stack simulator adopts carrys out the mode of each functional module of emulated protocol suite application adaptation layer, the parameter used due to each functional module is a lot, and the exploitation complexity when constructing presetting database is higher.
