Description

  The present invention is employed in, for example, a communication test apparatus that tests a communication device in accordance with various communication methods, and is a test target with a plurality of applications including scenarios and communication conditions according to communication methods, services, and test items, for example. The present invention relates to a session connection device and a session connection method for managing and maintaining a session with a resource including a communication device such as a mobile phone.

  2. Description of the Related Art Conventionally, a communication system includes a communication control device that processes a communication procedure corresponding to a lower layer of a network system, and an arithmetic processing device that has an upper layer processing function. In the arithmetic processing unit, there is a lower layer access program for notifying lower layers of requests of upper layers, and provides exclusive control and upper and lower interfaces.

  FIG. 14 is a block diagram showing a system configuration of a communication access method in a communication system disclosed in the following patent document as an example of converting different interfaces in this type of communication system.

  In the communication access method shown in FIG. 14, a request is made to the upper layer interface unit 52 that receives a request from an application program (communication program) 51 that is an upper layer (application layer) and to the communication control program 53 that is a lower layer (physical layer). The virtual communication resource management unit 55 interposed between the lower layer interface unit 54 and the lower layer interface unit 54 refers to the network database 56 and searches for communication control information according to the virtual communication resource from the application program 51 of the upper layer. The data is transferred to the physical layer communication control program 53 via the interface unit 54. As a result, general-purpose access to application software that is an upper layer is enabled only by changing the definition of the network database without being aware of the lower layer protocol and access interface.

Thus, in the conventional communication access method disclosed in Patent Document 1, when different interfaces are converted, the virtual communication resource management unit 55 serving as a manager is interposed between the upper layer interface unit 52 and the lower layer interface unit 54. Then, data was exchanged via the virtual communication resource management unit 55. Also, the virtual communication resource management unit 55 grasps all of the resource management.

It is a schematic block diagram in case the session connection apparatus is comprised by two or more.

  The session connection apparatus of the present example has a property of resident as software that manages a session between at least one application and at least one resource as a daemon process, and is adopted in, for example, a wireless communication tester (signaling tester). The The session connection apparatus of this example has an independent session for each application by using the session connection means (process) activated by the session connection control means as an intermediary.

  Here, the session referred to in this example includes communication performed along with scenario execution in the wireless communication tester and communication performed for preparation for scenario execution.

  As shown in FIG. 1, a session connection device 1 includes a resource 2 as an input / output means, an application 3 as an input / output control means, an information storage means (resource list) 4, a session connection means 5 as a process, and session connection control. Means 6 and display means 7 are provided for general configuration.

  Resource 2 is a hardware resource for actually performing signaling. For example, input / output of a signal of a predetermined communication method with a communication device under test including a wireless communication device such as a mobile phone is based on a predetermined scenario. Is going. The resource 2 is communicatively connected to the application 3 through the session connection means 5 that is activated under the control of the session connection control means 6 when a connection request from the application 3 is made.

  When the application 3 communicates with the communication device under test, a communication condition for setting the resource 2 such as a scenario, frequency, and level for controlling the resource 2 in a procedure according to the communication method, service, or combination thereof (Parameters) are stored, and communication with the resource 2 is performed according to these scenarios and communication conditions. When the application 3 communicates with the resource 2, the application 3 inquires the session connection control means 6 about the available resource 2. The application 3 extracts and selects the resource 2 to be used from the available resources 2 and requests it from the session connection control means 6. Further, the application 3 requests the session connection control means 6 to start a session with the resource 2 acquired by the session connection control means 6.

  Note that the description related to the acquisition timing of the resource 2 in this description does not specify the timing. In the following description, the acquisition of the resource 2 is performed after the application 3 requests the session connection control means 6 to start the session. It is written as it is. The acquisition timing of the resource 2 is determined by extracting and selecting the resource 2 to be used from the resources 2 that can be used by the application 3 and requesting it from the session connection control means 6. What is necessary is just to acquire until it requests | requires to the connection control means 6, and the session connection means 5 is started.

  The information storage means 4 stores, as various information related to the resource 2, for example, information such as resources that can be used and resources that are currently being used by the application 3 in a database. The information storage unit 4 also stores information related to a session at the time of session connection between the resource 2 and the application 3.

  In response to a connection request from the application 3 to the session connection control unit 6, the session connection unit 5 connects the requested application 3 and the predetermined resource 2 to perform communication, and the session connection control unit 6 Activated by. The session connection unit 5 establishes a new session between the resource 2 acquired by the session connection control unit 6 and the application 3 and performs session connection.

  The session connection control unit 6 analyzes information detected by hardware based on information from a device driver (not shown), and recognizes an available resource 2 based on the analysis result. Information about the resource 2 recognized at this time is stored in the information storage means 4. Further, the session connection control means 6 replies to the application 3 with the resources 2 that can be used in response to the inquiry from the application 3. Further, the session connection control means 6 acquires the resource 2 requested from the application 3, and mediates the session between the application 3 and the acquired resource 2 in response to the request for starting a session with the acquired resource 2. The session connection means 5 is activated. In addition, the session connection control means 6 recognizes all the process IDs of the session connection means 5 started by itself and stores them in the information storage means 4, and periodically checks the existence. When the process of the terminated session connection means 5 is found, the resource 2 acquired by storing and acquiring the record relating to the operating status of the session is updated in the information storage means 4.

  As shown in FIGS. 7 to 9, the display unit 7 performs various displays related to session connection between the resource 2 and the application 3 performed via the session connection unit 5. Specifically, when in the session connection state, as shown in FIG. 7, in the “Slots” tab, the slot (resource) being used (acquired) is displayed as “Busy”, and is free or unused. The slot (resource) is displayed as “Idle”. Also, the status of the session that is the user of the slot (resource) selected in the unit group list view is displayed in “Session”.

  As will be described in the resource detail display function described later, FIG. 7 shows that the application named “IDEAS” running on the apparatus main body uses all resources except slots C, D and RF2, and other applications are at least The situation using slot D is shown.

  The display of the list in the session connection state by the display means 7 is based on “Resources” shown in FIG. 8 and “Applications” shown in FIG. 9 in addition to the “Slots” shown in FIG. There is also a mode to display as. The display form in the list view changes depending on the tab, but in any display form, the session information related to the row selected in the list view is displayed in the “Session” below, and the displayed session is This is a target of forced disconnection by pressing the “Kill” button 8 as a forced release means.

  Next, an operation (reservation operation) related to the reservation of hardware resources of the session connection apparatus 1 having the above configuration will be described with reference to FIG.

  This reservation operation is an operation related to hardware resource reservation, and is triggered by receipt of the following command on the resource protocol. The following commands are merely examples, and any commands that give equivalent instructions may be used, and the commands are not limited.

  QUERY (status check): A command for inquiring the currently occupied resource occupancy status (including availability or not, the same applies hereinafter). As a response to this command, an occupation status including information indicating whether the implemented resource in the main machine is usable or not is returned.

  RESERVE (reservation instruction): A command for instructing acquisition (hereinafter also referred to as “occupation”) reservation of a specified resource. As a response to this command, the success or failure of resource acquisition (occupation) is returned.

  As shown in FIG. 2, in the reservation operation, the connection from the application 3 to the session connection control means 6 is made to the port number 8002 (the port number according to this description is an example and is not limited; the same applies hereinafter). Try. At this time, if there is a client (application 3) that is already connected, the connection is not reached. The session connection control means 6 accepts a connection from the application 3 if there is no connection being connected. Connection from the application 3 is only during transmission and reception of commands and responses unless there is a special reason. Therefore, the period during which the connection between the application 3 and the session connection control means 6 cannot be made is short and does not hinder the operation of the apparatus. Then, a “QUERY” command is sent from the application 3 to the session connection control means 6. As a response, the current connection status of the resource 2 is returned from the session connection control means 6 to the application 3. By examining this response, the application 3 determines whether or not the scenario can be executed by the application 3 on the designated actual machine.

  Next, a “RESERVE” command is sent from the application 3 to the session connection control means 6. This command includes the designation of resources to be secured. As this response, the resource occupancy status after securing is returned from the session connection control means 6 to the application 3. With this response, the application 3 knows the success or failure of resource acquisition. Thus, the reservation operation is completed, and the application 3 disconnects the connection to the port number 8002.

  In the example of FIG. 2, an example of connection from the external terminal device to the present device (main machine) is shown, but the reservation operation is also performed in the connection sequence from the application 3 installed on the main machine. Is called.

  The session connection apparatus 1 that performs the reservation operation as described above includes a session mediation function, a protocol conversion function, a resource management function, a resource detail display function, a resource forced release function, a session monitoring function, and an object download function as various functions. I have. Each function will be described below.

Session Mediation Function This session mediation function is an operation accompanying session connection for scenario execution by the application 3. The operation of the session mediation function will be described below with reference to FIG. In this session mediation function, first, when the session connection control unit 6 is activated, the session control connection unit 6 analyzes hardware detection information from a device driver (not shown) ((1) analysis), and based on the analysis result. To recognize resource 2 implemented. Then, the information of the recognized resource 2 is registered in the information storage unit 4 ((2) registration). In this state, an inquiry waiting state from the application 3 is entered.

  When the application 3 is activated and the application 3 makes an inquiry to the session connection control means 6 about what resources 2 are present ((3) inquiry request), the session connection control means 6 can be used for this inquiry. Resource 2 is read out from the information storage means 4 and answered to the application 3 ((4) inquiry response).

  Next, when there is a response from the session connection control means 6, the application 3 requests the resource acquisition from the session connection control means 6 in order to extract, select and acquire the resource 2 used by the application 3 ((5) request). . When the session connection control unit 6 receives a request for resource acquisition from the application 3, the session connection control unit 6 writes information indicating an unusable state or the like in the information storage unit 4 for the resource 2 scheduled to be used by the application 3 ((6) write).

  Subsequently, the application 3 requests the session connection control means 6 to start a session with the resource 2 ((7) session start). Upon receiving a session start request from the application 3, the session connection control means 6 acquires the resource 2 used by the application 3 ((8) acquisition), and mediates the session between the application 3 and the acquired resource 2 The session connection means 5 to be activated is activated ((9) activation). When the session connection means 5 is activated and the session connection control means 6 and the session connection means 5 are connected ((10) connection), the session by the session connection control means 6 and the application 3 has a different port number (for example, 8001). No.) and the like are taken over by the session connection means 5. As a result, the session connection unit 5 and the acquired resource 2 are connected ((11) connection), and communication is possible between the session connection unit 5 and the application 3 ((12) communication). As a result, a session is performed between the application 3 and the acquired resource 2 through the session connection unit 5 that takes over the session from the session connection control unit 6.

  Further, when the session is disconnected, when the communication between the application 3 and the session connection unit 5 ends ((13) ends), the session connection unit 5 disconnects the connection with the resource 2 ((14 ) Cutting). Then, a release request is sent from the application 3 to the session connection control means 6 ((15) release request). When the session connection control means 6 receives the release request from the application 3, the information indicating that the resource 2 used by the application 3 is vacant (available and not occupied) is stored in the information storage means 4. Write ((16) Open registration). As a result, the session between the application 3 and the resource 2 mediated by the session connection unit 5 is released.

  FIG. 4 shows an example of the operation sequence of the session mediation function described above. As shown in FIG. 4, regarding the session mediation function, the session connection control means 6 receives a “START” command and activates the session connection means 5 after accepting a session connection. The activated session connection means 5 performs an initialization process on the acquired resource 2 and takes over the session of the application 3 and the session connection control means 6 with the same port number (8001 in the example of FIG. 4). Specifically, when a session uses a socket (API group that controls TCP / IP), it is possible to take over the session by passing the handle value of the socket. The primitive that is a command for causing the resource 2 to execute the operation of the actual scenario thereafter is directly transmitted and received between the application 3 and the session connection means 5. In FIG. 4, it is expressed as one command and one response, but in reality, many primitives are sent and received in the section indicated as “connection state” during session establishment and communication. No session connection control means 6 intervenes in the traffic. In addition, the session is disconnected by the relationship between the application 3 and the session connection means 5. Basically, the session is disconnected from the application 3, and the session connection means 5 that detects the disconnection terminates itself through post-processing.

  As described above, in the session mediation function, when a connection request from the application 3 is received for the resource 2 managed by the session connection control means 6, a session connection having a function necessary for connection with the requested resource 2 is established. The means 5 is activated, and a session between the application 3 and the resource 2 is established through the activated session connection means 5. The application 3 first establishes a session with the session connection control means 6, but when the necessary information exchange is completed, the application 3 can directly communicate with only the resource 2.

Protocol conversion function With this protocol conversion function, all interfaces on the application 3 side can be unified into sockets (API group controlling TCP / IP). Further, the interface on the resource 2 side may be anything. The session connection unit 5 absorbs the difference in protocol between the application 3 side and the resource 2 side. In this example, there is a session connection means 5 corresponding to the resource 2, and the session connection control means 6 activates an appropriate session connection means 5 according to the requested resource 2.

  Hereinafter, an example of the protocol conversion function will be described with reference to FIGS. As shown in FIG. 5, for example, when the target resource is a resource unit on Compact PCI Bus, network communication is performed between the application 3 and the session connection unit 5 using TCP / IP. On the other hand, between the session connection means 5 and the resource 2 is shared memory communication using the physical memory in the resource 2 via the Compact PCI Bus. A ring buffer that uses a memory space in a ring shape is used for the physical memory. The data transmission from the application 3 to the resource 2 is first sent from the application 3 to the session connection means 5 in the Ethernet (registered trademark) frame format (header, Data body, Trailer). The session connection means 5 takes out only the Data body from the frame sent from the application 3 and sequentially writes it in a predetermined write position in the ring buffer in the resource 2. In data transmission from the resource 2 to the application 3, the session connection means 5 sequentially reads out data bodies in units of packets from a predetermined reading position for the data written in the ring buffer in the resource 2. The session connection means 5 sends it to the application 3 in a format according to the Ethernet (registered trademark) protocol.

  As shown in FIG. 6, when the target resource is a virtual resource unit, the session connection unit 5 also functions as a virtual resource, and TCP / IP is used between the application 3 and the session connection unit 5. Network communication. Similarly, the session connection means 5 that also serves as a virtual resource communicates with the virtual resource over the network using TCP / IP.

  Accordingly, the session connection control unit 6 activates the session connection unit 5 corresponding to the target resource, and relays between the application 3 and the virtual resource. In other words, in the protocol conversion function, the session connection means 5 basically does not know the communication contents, and only relays necessary data by converting the protocol.

  As described above, the session connection unit 5 that performs the protocol conversion between the application 3 and the resource 2 allows the session connection unit 5 to replace the resource. Further, it is possible to create a pseudo environment for testing the application 3 by making it appear that the resource 2 exists in a pseudo manner when viewed from the application 3.

Resource management function When the power is turned on, this resource management function collects information on resources 2 that can be managed by the session connection control means 6, and registers the state of the resources 2 in the information storage means 4 as a database based on the collected information. To do.

  When the application 3 requests the use of the resource 2, the number of resources is managed, the resource 2 requested by the application 3 is allocated, and the allocation state is reflected in the database of the information storage unit 4. Further, even when the application 3 releases the resource 2, the allocation state of the resource 2 for the application 3 is reflected in the database of the information storage unit 4.

Resource detail display function In this resource detail display function, as shown in FIGS. 7 to 9, the contents of the database of the information storage means 4 reflecting the state of the resource 2 managed by the session connection control means 6 are displayed. The information is displayed on the display screen of the means 7. In the example of FIG. 7, “Slots” is used as an axis, in the example of FIG. 8, “Resources” is used as an axis, and in the example of FIG. 9, “Applications” is used as an axis, and the status at the time of session connection is displayed as detailed resource information. . To explain further by taking FIG. 7 as an example, when the “Slots” tab is selected, Type (type: communication method, etc.) and Status (state) are displayed for each slot. In the example of FIG. 7, the type of Slot A is W-CDMA, the status is Busy, the type of Slot B is TDMA, the status is Busy, the type of Slot C is None (no slot (resource) is mounted), and the Status is Idle. It indicates that the type of SlotD is cdma2000 and the status is Busy. Also, below the display screen, information of Application, Host, PID, RFs, Slots, and TE is displayed as Session. In the example of FIG. 7, Application: IDEAS, Host: localhost, PID: 2044, RFs: RF1 check box, Slots: A, B check box, TE: Handset, ISDN check box is checked Is displayed. This display shows that an application 3 named “IDEAS” that is running on the main machine uses all resources 2 except slots C, D, and RF2, and other applications use at least slot D. Is shown. In this display screen, a “Kill” button 8 for forcibly releasing resources is displayed.

Resource forced release function With this resource forced release function, when the “Kill” button 8 is pressed in the session display shown in FIGS. 7 to 9, the resource 2 reserved by the application 3 is forced through the session connection control means 6. Open. More specifically, as shown in FIG. 10, when a disconnect operation is performed by pressing the “Kill” button 8, the session connection control means 6 is in operation, triggered by a human intervention operation instructing the forced disconnection of the session. Issue an end instruction to the session connection means 5. When the session connection unit 5 receives an end instruction from the session connection control unit 6, the session connection unit 5 disconnects the session with the resource 2 and performs end processing, and disconnects the port number 8001 of the application 3. The application 3 knows the forced disconnection of the session by detecting the disconnection of “Port # 8001 disconnection”. Thereby, the scenario thread or the like is terminated. When the session connection control unit 6 detects the end of the process of the session connection unit 5 by periodic monitoring, the session connection control unit 6 updates the session operation status and the resource occupation status, and stores the update information in the information storage unit 4 to release the resource 2. To do.

Session monitoring function In this session monitoring function, the session connection means 5 monitors the session held by the session mediation function, and releases the resource 2 when the session expires. More specifically, as shown in FIG. 11, when the session connection unit 5 receives “disconnect port # 8001” from the application 3 as the end of the scenario thread, the session connection unit 5 detects the disconnection and ends the process. The connection between the session connection unit 5 and the resource 2 is released when the process of the session connection unit 5 is terminated by detecting disconnection of the session connection unit 5. When the session connection control means 6 detects the end of the process of the session connection means 5 by periodic monitoring, the session connection control means 6 updates the session operating status and stores the update information in the information storage means 4 to release the resource 2.

Object download function In this object download function, when the session connection device 1 of this example is controlled from the outside by an external terminal device, for example, not only commands but also objects such as control programs and FPGA data are assigned to the resource 2 It can be sent to. In this case, the session connection means 5 has a download procedure.

  By the way, in the above-described form, the case where there is one session connection means 5 that takes over the session between the application 3 and the resource 2 has been described as an example. It is also possible to adopt a configuration in which a plurality are activated in response.

  FIG. 12 is a schematic configuration diagram when two session connection means 5 are activated in one apparatus. In the example of FIG. 12, two resources 2 (2A, 2B) used in the application 3 are connected to the session connection control unit 6 in response to a connection request from the application 3 to the session connection control unit 6 by the session mediation function described above. Earned by. Then, the session between the application 3 and the resource 2A is taken over by the session connection unit 5 (5A), and the session between the application 3 and the resource 2B is taken over by the session connection unit 5 (5B).

  As described above, according to the configuration of FIG. 12, a session is performed with respect to one application 3 with two resources 2A and 2B via two independent session connection means 5A and 5B.

  In the example of FIG. 12, the session connection means 5A, 5B is configured to take over the session for each resource 2A, 2B. However, the portion indicated by the alternate long and short dash line in FIG. A configuration in which a session between the two resources 2A and 2B is mediated by one session connection means 5 may be employed. In this case, the communication from the application 3 to the resources 2 </ b> A and 2 </ b> B is determined with respect to which resource 2 by the command from the application 3. According to these configurations, it is possible to create an environment that includes a plurality of base stations in a pseudo manner by a single device.

  Moreover, as a structure which starts the some session connection means 5, it can also comprise as FIG. In the example of FIG. 13, the session connection device 1 is composed of two devices. Here, one device on which the application 3 is installed is a higher-level device 1A, and the other device is a lower-level device 1B. Note that one of the upper apparatus 1A and the lower apparatus 1B can be configured by an external terminal device such as a personal computer. With the session mediation function described above, on the host device 1A side, in response to a connection request from the application 3 to the session connection control means 6A, the resource 2A used in the application 3 is acquired by the session connection control means 6A. Then, the session between the application 3 and the resource 2A is taken over by the session connection means 5A. In the example of FIG. 13, when a connection request is made from the application 3 to the session connection control means 6A in the upper apparatus 1A, the application 3 also uses the resource 2B of the lower apparatus 1B. An inquiry is made from the control means 6A to the session connection control means 6B of the subordinate apparatus 1B. The resource 2B is acquired by this inquiry, and a response is returned from the session connection control means 6B of the lower apparatus 1B to the session connection control means 6A of the upper apparatus 1A. Thereby, the session between the application 3 and the resource 2B of the lower level apparatus 1B is taken over by the session connection means 5B of the lower level apparatus 1B. Then, the application 3 on the higher-level device 1A side performs a session between the two resources 2A and 2B divided into the higher-level device 1A and the lower-level device 1B through the session connection means 5A.

  The acquired resources 2A and 2B are resources registered in the respective information storage means 4A and 4B included in the higher-level device 1A and the lower-level device 1B. The registration of the resources 2A and 2B may be managed collectively in the information storage unit 4A of the higher-level device 1A.

  According to this configuration, for the management of different types of measuring instruments, for example, a system combining a wireless communication tester (signaling tester) that implements the present invention with a spectrum analyzer or a signal generator can be constructed. For example, simpler and finer control than GPIB is possible. It becomes possible. In addition, the file transfer has an effect that, for example, a measurement result, an object can be downloaded, and the like.

  Note that the configuration and method of this example are effective even when there are a plurality of applications 3 or a plurality of session connection means 5 and session connection control means 6 in one or a plurality of apparatuses. . In that case, each application 3 has an independent session.

  The session connection apparatus of the present example described above can be specifically used for session connection between software installed in a test apparatus of a wireless communication device such as a mobile phone. More specifically, the test apparatus in which the session connection apparatus 1 of this example is mounted functions as a pseudo base station. Then, for each type of communication device under test, the communication method used by the communication device under test (for example, W-CDMA, cdma2000, GSM, etc.) and the application and device under test are actually used according to various test item scenarios. Pseudo communication with communication equipment. As a result, various tests of the application under test and the application in the apparatus can be performed.

  And according to the session connection apparatus and the session connection method of this example, each application 3 has an independent session by the session connection means 5 that performs the session between the application 3 and the resource 2. Communication can be performed without affecting the application.

  If the session mediation function is used, even if the number of sessions increases, the load on the session connection control means 6 is only a fixed amount, and the influence on the system is small.

  By the way, in the above-described embodiment, the case where the session connection apparatus and the session connection method of this example are adopted for the session connection between the software implemented in the test apparatus of the wireless communication device is described as an example, but the present invention is not limited to this. Of course, other forms, examples, operation techniques, and the like made by those skilled in the art based on the form of the present example are all included in the scope of the present invention.
