New AT order is used for supporting test and activates the collection of PDU information (Packet Data Unit) and parameter information.When following the tracks of, be sent to network and all Packet Data Units (PDU) of receiving from network tracked mobile communication equipment.Handling tracking data preferably carries out in the equipment that separates (NT).The parameter of air interface and in mobile communication equipment internal calculation parameter by from protocol entity (for example, CC calls out control) or control they the soft-component solicited message of task and tracked.All PDU trace informations are based on known standard itself.
The new function of the AT command interpreter 14 of mobile communication equipment is these new functions of decipher, and providing will be as from the response of the internal part of mobile communication equipment and the information of supplying with, and response is returned to outer testing system.Tracking message and the request responding that is intended for use protocol entity sent to network test system via the AT command interpreter.
In addition, support the standard AT command according to prior art, these orders are to need in being connected between tester NT and mobile communication equipment 1.The connection that this order control is discussed, and only influence the connection of being discussed.This order for example comprises:
-ATE, command echo,
-ATV determines response format,
-ATI, the request identifying information,
-ATZ resets to default configuration,
-AT﹠amp; V watches active configuration, and
-AT﹠amp; F recovers factory settings.
Test macro is for example implemented by means of the specialized application that will be connected to normal mobile communication equipment to be tested, and it receives the operation of AT order and carry out desired by means of the DTE-DCE interface.
Next let us checks the structure and the system of specialized application with reference to Fig. 2.In the embodiment of this system, utilize the AT command interpreter 14 of mobile communication equipment 1, make necessary change, so that implement according to operation of the present invention for this interpreter.The critical piece of system is actual network tester NT, and it comprises test control test macro unit 16, and it also receives trace information and the request of carrying out protocol entity.In the scope of this explanation, connect control unit 13 and also belong to same physical equipment with this tester NT, this unit creates calling or grouped data shifts and network tester NT follows the tracks of the functional of it.Depend on the medium that using at network test system NT with transfer of data between the different media module MM (comprising a so-called terminal adapter), wherein for example infrared connection (IrDA) is mentioned in the above.Each connection by means of different medium is described to session separately.Logic connection to the AT command interpreter is created each physical connection 17 and 18 that is used for media module MM.These several (for example, USB connect) in connecting also can be arranged, and network tester can be used as two sessions and handles in the AT command interpreter in this case.A session is to be used to follow the tracks of and control the functional of tester, and another session is to be used to control actual data connect.Therefore tester NT connects by means of for example USB or two bluetooths connect or bluetooth connects and is connected with an IrDA or an IrDA connection is connected with a RS232 and is connected to mobile communication equipment 1, so that create two sessions.
In mobile communication equipment 1, the communication between different units be be intended for use the normal mobile communication equipment that uses in identical mode carry out.Trace information is obtained the additional attribute of wherein comparing with normal version by using product development software.Tracking can be activated and is deactivated in when operation mode.Protocol element 5 and 6 (Fig. 1) and other unit send trace information via interface 3.The tracking that receives from protocol entity, it is different mutually that so-called system information traces is followed the tracks of with packet system information.These are followed the tracks of and directly not to be sent to tester NT because with the timing of their associated be security information, why Here it is is stored in tracking and is used to the reason that cushions and delay time in the system info storage 15 of the soft-component SW that handles the DTE-DCE interface.After suitable time-delay, parts SW sends to tester NT to the tracking of being stored by numeral order.
Tester NT is connected to mobile communication equipment 1 in the mode that depends on physical connection, and by this mode, the media module MM (one or two media module) that is used by tester knows that this connection produces.After this, media module MM sends to the parts SW that handles interface to necessary message, connects 17,18 so that create logic.By these connections, tester NT can send AT order 10 (Fig. 1) to AT command interpreter 14, and for this AT command interpreter, it sends a response 11.Under the normal mode of mobile communication equipment 1, normal AT order be possible (for example, AT*CHSN), and the AT of network tester (NT) order be unallowed (for example, AT*NBALOCK) and produce a mistake.After AT*NTESTSYSTEM=1 was given mobile communication equipment 1, mobile communication equipment was transferred to network tester mode in order, and it no longer accepts normal AT order, and normal AT order only produces a mistake now.Alternatively, the configuration that utilizes normal AT order to make still is effectively, but they can not be changed or be presented now.In the pattern of discussing, only accept special AT order.When test session finishes, provide order AT*NTESTSYSTEM=0, after this mobile communication equipment turns back to normal condition, and normal AT order is possible.
When network tester NT sends order AT*NLOGGING=1 to mobile communication equipment, activation trace.AT command interpreter 14 receives the order of being discussed, confirm it, and with regard to the AT command interpreter, (for example send, via internal interface, such as ISI, intersystem interface) message is to monitor server 19, in the sub-piece of this message, determine which tracking should be sent to the parts SW that handles the DTE-DCE interface.After activation, tracking data is sent to these parts in message, and its content is further sent to network tester NT.Follow the tracks of and also can be deactivated.
, in the AT of mobile communication equipment command interpreter and, if necessary, then also require aspect configuration file, to change according to operation requirement of the present invention changing aspect the functional control.For example, a module handling determined new specific AT order is added to the AT command interpreter.Necessary change is also carried out in the built-in function of interpreter, by this change, for example, if mobile communication equipment 1 is not to be in network tester mode, then stops the tester order.Might to receive trace information and give DTE interface 3 it from tracking unit 19 in order to make, also must change the Control Software core functionality.Therefore the Control Software of mobile communication equipment 1 also needs to be used for the container 15 of system information traces, and in fact it means that of the piece that receives for example is by lists of links or several tabulation.
The response that order provides to AT is divided into three classes.At first, the standard A T response (AT command response) with ASCII form (ascii character) is discussed.The second, the ISI that comprises trace information (agreement PDU tracking) is discussed follows the tracks of the indication response.This trace information is own known and has been used in conjunction with the test according to prior art that this information is determined in addition in the appropriate protocol standard.A part of information of using in internal interface 20 can be removed before giving network tester information, because information may be unnecessary.The 3rd, the message response for the request that is sent to protocol entity is discussed.Yet the unnecessary field of this response was removed before network tester in the last response of transmission.
When activation trace, the AT that is used to the login order that receives from the outside activates several tracking groups and to the request of protocol entity in that mobile communication equipment 1 is inner.Order substitutes with following the tracks of the request of activation and the request of inquiring in inside.Several external commands are arranged in the use, and they make and might optionally collect data and additionally dispose its internal technology standard.
Internal trace Indication message and can before giving network tester them, be provided to suitable prefix from the response message of protocol entity, like this, standard A T response and can easily separate with the response of data collection associated.
On the basis of the above condition that provides, the functional necessary change and the software change of mobile communication equipment are tangible to those skilled in the art.Detailed embodiment can change as required.The present invention only limits to the above example that provides, but it can change within the scope of the appended claims.
