Description

  The present invention relates to a service providing system and a method for providing the same, and the service providing system of the present invention particularly includes a SIP environment that operates based on a Session Initiation Protocol (SIP) and a Web (World The present invention relates to a system that provides services to connected clients by linking applications to each other by fusing different environments such as Wide Web) environments. The service providing method of the present invention relates to a method of providing a service by, for example, linking applications operating in different environments, for example, the achievement status of the purpose of communication by recording a VoIP communication started from a web browser, for example. It is related to the realization of the communication process management type AP that manages the system and supports the execution of the communication and the achievement of the purpose.

  Conventionally, a SIP-based AP (APplication) environment and a Web-based AP environment have not been integrated, and have been realized as separate AP environments. This is because the conventional Web-AP environment is used to construct information-providing AP services provided by corporate information systems and ISPs (Internet Service Providers), while the SIP-AP environment is used to construct telephone services. It depends on what has been done. That is, each environment is used for different purposes.

  Further, when linking and connecting server environments realized by such different communication protocols, a system that mediates a protocol conversion gateway is generally employed. As the protocol conversion gateway, an HTTP-SIP conversion gateway that realizes an interconnection conversion function between HTTP (Hyper Text Transfer Protocol), which is a protocol in the Web environment, and SIP, which is a protocol in the SIP environment, is used.

RFC3261, Internet <URL: http://www.ietf.org/rfc/rfc3261.txt> JSR116, Internet <URL: http://jcp.org/aboutJava/communityprocess/final/jsr116/index.html>

  By the way, the HTTP-SIP conversion gateway makes it possible to realize only a simple function that is incorporated in advance in the HTTP-SIP conversion gateway mechanism and operates according to the protocol conversion rule. However, for example, when a plurality of people manage a plurality of communications under a single purpose, it is known that a single communication system using the HTTP-SIP conversion gateway or a conversion gateway cannot be flexibly implemented.

  As a difficult example of this implementation, a relatively large-scale system proposal corresponds to this. More specifically, a system proposal in which a plurality of salesmen and SEs (Sales Engineers) usually develop a business while communicating with a plurality of customer contacts and persons in charge is considered. In this proposal, multiple people will carry out multiple communications such as business negotiations and technical proposals in order to achieve the objectives such as contract closing and system construction. For this implementation, it is known that a communication system should be constructed for each purpose.

  In addition, it is preferable that the achievement status of the objective is made to correspond to the presence on the database in the SIP environment, and the status change due to the implementation or the status changed is notified. However, when the system is constructed in this way, the system holds the HTTP transaction for a long time. Therefore, it can be seen that the exemplified system is not an appropriate implementation method from the viewpoint of effective use of resources and realization of a user interface as a practical application.

  The present invention has been made in view of the above problems, and an object thereof is to provide a service providing system and a providing method thereof that can realize centralized situation management based on a viewpoint of performing a plurality of communications.

In other words, it can be said that communication ends when it achieves its purpose. From the perspective of achieving the objectives, there are several stages of communication. Each of the stages is called a status as described above.

  The status in communication is roughly classified into completion, waiting for an answer, waiting for a message, and a re-request schedule. The completion status indicates that the goal has been achieved. The answer waiting status means that the requested item is scheduled. The message waiting status indicates that the request item is not transmitted from the message to the respondent. Further, the re-request schedule status indicates that the request item from the requester has not yet been transmitted.

  Actually, the situation where the request is not transmitted is equivalent to the situation where the message waiting status and the scheduled re-request status are trapped. More specifically, there are situations where an e-mail has been sent to a communication partner but this partner has not read, a situation where a message memo has remained, a situation where the message person has forgotten, and the like.

  The communication is repeatedly executed until the status is finally completed. If this status change can be centrally managed and displayed by a certain Uniform Resource Locater (URL), for example, not only the communication party but also the third party can visually grasp the achievement status for the purpose of communication. As a result, communication is reliably performed. This can avoid human errors such as forgetting answers and forgetting requests. In addition, for communication to achieve important objectives, managers and supervisors can manage the progress and status of communications appropriately, and managers and supervisors can appropriately provide instructions and hints as appropriate. Can be given.

  Based on the basic concept as described above, as shown in FIGS. 5 and 6, the operation of accessing the SIP system 12 from the Web system 14 and generating the service proxy UA will be described in order. The web browser 50 of the web client 20 in FIG. 4 issues an execution request for “service generation” to either the web server 34 or the web-AP server 38 at time T10 (Gen._REQ. 140). The user information included in the issued service generation request includes information related to a contract such as the user's name, address, age, and address information, and information used for authentication when using the system. In general, an execution request for “service generation” is performed using a GUI (Graphical User Interface) provided by the Web server 34 displayed on the Web browser 50.

  Next, either one of the Web server 34 and the Web-AP server 42 receives a start signal (for the proxy UA generation access function unit 104 based on the “service generation request (Gen._REQ. 140)” sent from the Web browser 50 ( Launching) 142 is generated. Either the Web server 34 or the Web-AP server 42 supplies the activation signal 142 generated at time T12 to the service proxy UA management unit 98.

  The service proxy UA management unit 98 uses the component API 134 based on the activation signal 142 to activate the proxy UA generation access function unit 104. The proxy UA generation access function unit 104 generates an activation signal 144 that activates the cooperation management unit 96. The activation signal 144 includes request information (Gen._REQ.) For accessing the proxy UA generation function unit 62 of the SIP system 12 from within the Web system 14. The proxy UA generation access function unit 104 outputs the activation signal 144 to the cooperation management unit 96 at time T14.

  The cooperation management unit 96 is activated in response to the activation signal 144. The linkage management unit 96 selects one of SOAP, CORBA, and the like and transmits “access request” information using the selected communication protocol when performing information transmission to the SIP system 12 during this startup. A proxy UA generation access request (Gen._REQ.) 146 is generated. The cooperation management unit 96 communicates by supplying a proxy UA generation access request 146 to the cooperation management unit 58 existing in another domain on the network 16 at time T16. The cooperation management unit 58 receives the proxy UA generation access request 146 supplied from the cooperation management unit 96, and generates an activation signal 148 that activates the proxy UA generation function unit 62. The activation signal 148 includes “proxy UA access request” information. The cooperation manager 58 outputs the activation signal 148 to the proxy UA generation function unit 62 of the service proxy UA manager 54 at time T18.

  The proxy UA generation function unit 62 receives the activation signal 148, generates a proxy UA, further generates an activation signal 150, and outputs it to the proxy UA registration function unit 64 at time T20. The proxy UA registration function unit 64 registers the proxy UA information in the SIP-DB 24 managed by either the SIP-AP server 26 or the SIP server 22 at the time T22 upon activation (Registration 152).

  The SIP-DB 24 searches based on the registered proxy UA information, and outputs a search result (Result) 154 to the proxy UA generation function unit 62 at time T24. The search result is generated SIP-URI (Uniform Resource Identifier) information. The proxy UA generation function unit 62 receives the search result and generates an activation signal 156 including the search result. The activation signal 156 activates the cooperation management unit 58. The service proxy UA management unit 54 outputs the activation signal 156 to the cooperation management unit 58 at time T26.

  The cooperation manager 58 is activated by the activation signal 156. The cooperation management unit 58 selects any one of SOAP, CORBA, and the like and uses the selected communication protocol in replying the search result generation SIP-URI information. Using this communication protocol, the cooperation management unit 58 communicates the result of the “service generation request” with the cooperation management unit 96 as a proxy UA generation response (Gen._RES.) 158. The cooperation management unit 96 receives the result of the “service generation request”. The cooperation management unit 96 outputs a response signal (Response) 160 including this result to the proxy UA generation access function unit 104 at time T30. The proxy UA generation access function unit 104 receives the execution result of the component API 134 of the service proxy UA management unit 98, and sends a response signal 162 as an execution result to either the Web server 34 or the Web-AP server 38 at time T32. Output. The execution result is user information data (generated SIP-URI information) obtained by a search on the SIP-DB 24.

  Either the Web server 34 or the Web-AP server 38 processes the search result of the user information into a format that can be displayed by the Web client. The displayable format includes, for example, a SIP-URI format. Either the Web server 34 or the Web-AP server 38 supplies the data (Service_INF) 164 processed at time T34 to the Web browser 50 that has made the “service generation request”. The web browser 50 displays the result of “service generation request”.

  Next, the operation of presence setting will be described with reference to FIGS. The web browser 50 shown in FIG. 7 issues a “service presence setting” execution request (Set_REQ.) 170 as a presence setting request at time T40. This execution request corresponds to the specification of SIP-URI. The execution request of “service presence setting” includes user information. The user information includes information related to contracts such as the user's name, address, age, and address information, and information to be authenticated when using the system. Also, the service presence setting request information includes contents representing the service status, and the status is designated. This state includes, for example, “waiting for execution”, “processing”, “finished”, etc., and is set as presence. Generally, these information settings in the “service presence setting” are performed using a GUI provided by the Web server 34 displayed on the Web browser 50. The web browser 50 supplies the “service presence setting” 170 to one of the web server 34 and the web-AP server 38.

  One of the Web server 34 and the Web-AP server 38 generates an activation signal 172 based on the supplied execution request for “service presence setting”. The activation signal 172 is supplied to the service proxy UA management unit 54 at time T42. The service proxy UA management unit 54 activates the presence setting access function unit 110 by using the component API 134 built in by the activation signal 172. The presence setting access function unit 110 generates an activation signal 174 including information related to presence setting, and supplies the activation signal 174 to the cooperation management unit 96 at time T44.

  The cooperation manager 96 receives the activation signal 174 and is activated. Here, the cooperation management unit 96 selects one of SOAP, CORBA, and the like when transmitting information to the SIP system 12 in this activation, and uses the selected communication protocol to make a “presence setting request”. “A presence setting access request (Set_REQ.) 176 including information is generated. The cooperation management unit 96 communicates by supplying a presence setting access request 176 at time T46 to the cooperation management unit 58 existing in another domain on the network 16.

  The cooperation management unit 58 receives the presence setting access request 176 supplied from the cooperation management unit 96 and generates an activation signal for activating the presence setting function unit 68. The activation signal includes “presence setting access request” information. The cooperation management unit 58 outputs the activation signal 178 to the presence setting function unit 68 of the service proxy UA management unit 54 at time T48.

  The presence setting function unit 68 is activated in response to the activation signal 178. By this activation, the presence setting function unit 68 accesses the SIP-DB 24 as a proxy UA so as to change the presence information setting in the SIP-DB 24 to the presence information included in the activation signal 178 (Change 180). The SIP-DB 24 is managed by at least one of the SIP-AP server 26 and the SIP server 22.

  After this change, although not shown in FIG. 7, the proxy UA information search function unit 74 is activated and searches the SIP-DB 24. The SIP-DB 24 outputs the presence information search result to the proxy UA information search function unit 74 at time T52 (Response 182). The proxy UA information search function unit 74 supplies the presence result search result supplied to the presence setting function unit 68.

  By the way, the presence setting function unit 68 notifies the SIP softphone 46 of the change of the presence information registered in the SIP-DB 24, for example. This change notification is a search processing sequence performed after time T52, and the search processing sequence is executed by the number of watchers asynchronously (Notify 184a).

  The service proxy UA embedding unit 54 supplies the activation signal 184 including the search result to the linkage management unit 58 at time T54 and activates it. The cooperation management unit 58 communicates with the cooperation management unit 96 at time T56 using any one of SOAP, CORBA, and the like (Response 186). The cooperation management unit 96 supplies a response signal 188 to the presence setting access function unit 110 of the service proxy UA management unit 98 at time T58. The response signal 188 includes a result of “presence setting request”, and when the normal setting is successful, the set presence content is transmitted as a result such as a status of “waiting for execution”. When the setting is unsuccessful, the response signal 188 is transmitted as NG (No Good) as a result.

  The presence setting access function unit 110 in the service proxy UA management unit 98 supplies the execution result of the component API 134 to either the Web server 34 or the Web-AP server 38 at time T60 (Response 190). This execution result indicates user information data obtained by a search in the SIP-DB 24. Either the Web server 32 or the Web-AP server 36 has a format in which the execution result can be displayed. Examples of the format include a SIP-URI format. One of the Web server 34 and the Web-AP server 38 supplies and displays the result of “service presence setting request”, that is, the service presence (Service_Presence) 192, to the Web browser 50 requested at time T62.

  By operating in this way, it is set in the SIP-DB 24 of the SIP system 12 in response to the presence setting request from the Web browser or Web client, and the setting status in the SIP-DB 24 is sent to the client that has requested it as a response signal. Can be provided easily.

  Further, the message transmission operation in the communication system 10 will be briefly described with reference to FIGS. The components used are exactly the same, and the same reference numerals are used for the components.

  The Web browser 50 issues a “message transmission” execution request (Send_REQ.) 200 to either the Web server 34 or the Web-AP server 38 at time T70. The user information and GUI handled here are the same as those described above. Either one of the Web server 34 and the Web-AP server 38 generates an activation signal 202 based on the received “message transmission request” (Send_REQ.) 200, and transmits the activation signal 202 to the message transmission access function unit at time T72. Supply to 112. The activation signal 202 activates the message transmission access function unit 112 using the component API 134.

  The message transmission access function unit 112 activates the cooperation management unit 96 at time T74 (Launching 204). The link embedding unit 96 communicates with the link management unit 58 existing in another domain on the network 16 at time T76 using any one of SOAP, CORBA, and the like. The cooperation manager 58 receives the “message transmission request” (Send_REQ.) 206. The cooperation management unit 58 activates the message transmission function unit 70 at time T78 (Launching 208).

  The message transmission function unit 70 sends a message 210 to the SIP softphone 46, which is a SIP client, at time T80 and displays it on the monitor. The SIP client corresponds to the message recipient. The message transmission function unit 70 receives a message response from the SIP softphone 46 (not shown). The message transmission function unit 70 supplies the activation signal 212 including the response content to the cooperation management unit 50 at time T82 and activates it.

  The link embedding unit 58 communicates with the link management unit 96 at time T84 using any one of SOAP, CORBA, and the like to send a response of the transmission result (Response 214). The cooperation management unit 96 receives the result of the “message transmission request” issued by the Web browser 50. The cooperation management unit 96 transmits the message to the message transmission access function unit 88 of the proxy UA management unit 76 at time T86 (Response 216).

  The message transmission access function unit 112 receives the result of the supplied “message transmission request”, and outputs it to either the Web server 34 or the Web-AP server 38 as the execution result of the component API 134 at time T88 ( Response 218). Either the Web server 34 or the Web-AP server 38 processes the message transmission request result into a format that can be displayed. For example, there is a SIP-URI format. One of the Web server 34 and the Web-AP server 38 supplies a response signal (Response 220) to the Web browser 50 at time T90. The Web browser 50 displays the result of “message transmission request” on the monitor.

  By operating in this way, the proxy UA management units 54 and 98 and the linkage management units 58 and 96 are used to track services on the web and from one system to the other system that composes messages in the communication system 10. Notification can be made, and the notification result can also be supplied to the transmission source. In addition, since HTTP transactions are not suspended for a long time, effective use of resources and realization of a user interface as a practical application can be easily performed.

  Next, operations of call attempt generation, status setting, status change notification, and status retention notification in call attempt management will be described in order.

  Call attempt generation will be described with reference to the operation sequences of FIGS. Communication is started so that the Web browser 50 achieves the purpose. Before this start, the Web browser 50 issues a contact list request (List_REQ. 230) to either the Web server 34 or the Web-AP server 38 at time T100.

  Upon receiving the contact list request, either the Web server 34 or the Web-AP server 38 responds to the request to the Web browser 50 as a candidate to be communicated with a contact list composed of a plurality of call destinations at time T102 as a response to the request. Output (List_Disp. 232). With this supply, the Web browser 50 displays the contact list supplied on the Web page. The contact list includes information such as the name, telephone number and presence of the communication destination.

  The user selects a specific item displayed on the Web browser 50 at time T104 as a contact destination (List_SEL. 234). From this, transmission is performed. Thus, in general, communication is started by sending a new message from a purpose-specific Web page.

  The activation signal 236 including the information of “contact list selection” (List_SEL. 234) supplied by either the Web server 34 or the Web-AP server 38 is generated. The activation signal 236 is output to the call attempt management unit 100 at time T106. The call attempt management unit 100 activates the generation access function unit 118 using the component API 136 corresponding to the activation signal 236.

  The generation access function unit 118 generates an activation signal 238 including information on contact list selection for the cooperation management unit 96. The generation access function unit 118 outputs the activation signal 238 to the cooperation management unit 96 at time T108. The cooperation manager 96 receives the activation signal 238 and activates it.

  Here, the cooperation management unit 96 selects one of SOAP, CORBA, and the like to transmit information to the SIP system 12 during this startup, and uses this selected communication protocol to create a “call attempt generation”. A request (CA_Gen._REQ.) 240 including “request” information is generated. The cooperation manager 96 supplies a request 240 including “call attempt generation request” information to the cooperation manager 58 existing in another domain on the network 16 at time T110 and communicates.

  The cooperation management unit 58 generates an activation signal for the generation function unit 76 of the call attempt management unit 54. The cooperation management unit 58 outputs the activation signal 242 to the generation function unit 76 at time T112. The activation signal 242 activates the generation function unit 76 using the component API 94 corresponding to the call attempt management unit 56. The generation function unit 76 generates a call attempt instance (Instance 244) corresponding to the requirement. The generation function unit 76 stores the instance 244 generated in the SIP-DB 24 at time T114 (registration). The SIP-DB 24 outputs a response signal (Response) 246 to the registration to the generation function unit 76 at time T116.

  The generation function unit 76 receives the response signal 246 from the SIP-DB 24 and knows the completion of the call attempt generation. Upon receipt of this completion, the generation function unit 76 generates an activation signal 248 that activates the cooperation management unit 58. The generation function unit 76 outputs the activation signal 248 to the cooperation management unit 58 at time T118. The cooperation manager 58 is activated in response to the activation signal 248.

  The cooperation management unit 58 uses any one communication protocol such as SOAP and CORBA in order to send a transmission result to the call attempt management unit 100. The cooperation management unit 58 communicates with the cooperation management unit 96 at time T120 using the selected communication protocol, and transmits a response signal 250. Further, the cooperation management unit 96 outputs the result (Response) 252 of the “call attempt generation request” obtained by communication with the cooperation management unit 58 at time T122 to the generation access function unit 118.

  Next, the call attempt management unit 100 returns the result received by the generation access function unit 118 to either the Web server 34 or the Web-AP server 38 at time T124 as the execution result of the component API 94. Either one of the Web server 34 and the Web-AP server 38 processes into a format that can display that the corresponding contact destination is selected. Examples of processing include reverse display.

  Either the Web server 34 or the Web-AP server 38 outputs the result (Result) 256 of “contact list selection” processed at time T126 to the Web browser 50. The web browser 50 displays the supplied result 256.

  Thereafter, a series of operations from time T12 to T32 is continued in the operation sequence shown in FIG. After this, it is operated to establish communication. Either the Web server 34 or the Web-AP server 38 generates an activation signal 258 for the cooperation management unit 96 at time T128. The activation signal 258 includes request information for causing one of the SIP-AP server 26 and the SIP server 22 to “establish a call”. The “call establishment” request information is, for example, a “call establishment” request between the SIP client 46 that is the contact selection destination and the SIP client 48 of the user. The cooperation management unit 96 supplies the “call establishment” request (Contact_REQ.) 260 to the cooperation management unit 58 at time T130 using the selected communication protocol.

  The cooperation manager 58 generates an activation signal 262 including request information for “call establishment” at time T132. The cooperation manager 58 outputs the activation signal 262 to either the SIP-AP server 26 or the SIP server 22 at time T132. Either one of the SIP-AP server 26 and the SIP server 22 receives the activation signal 262 and uses, for example, a 3PCC (3rd Party Call Control) procedure to select a contact at time T134. A call control signal (Call_CON.) 264 is transmitted to the SIP client 46. Similarly, one of the SIP-AP server 26 and the SIP server 22 transmits a call control signal 266 to the user's SIP client 48 in the same manner. As a result, a call is established between the SIP client 46 and the SIP client 48.

  By operating as described above, the communication system 10 automatically generates a call attempt corresponding to a message and a proxy UA that notifies the status change of the message at the same time as making a call, and establishes communication.

  Next, the status setting call attempt generation operation will be described with reference to FIGS. 13 and 14. FIG. First, the SIP client 48 in communication performs a disconnect operation at time T140. As a result, “Call disconnection (Call_CUT 270)” is transmitted to one of the SIP-AP server 26 and the SIP server 22. Either one of the SIP-AP server 26 and the SIP server 22 transmits a disconnection (Call_CUT) 272 to the SIP client 46 that is a communication partner at time T142. Thereby, the SIP clients 46 and 48 end the communication.

  At the same time, one of the SIP-AP server 26 and the SIP server 22 generates an activation signal 274 for activating the cooperation management unit 58 including call termination information. One of the SIP-AP server 26 and the SIP server 22 outputs an activation signal 274 to the cooperation management unit 58 at time T144. The cooperation management unit 58 notifies the cooperation management unit 96 of the end of communication using the communication protocol selected at time T146 (COM._END 276). The linkage management unit 96 notifies the call termination between the SIP client 46 as the contact selection destination and the user's SIP client 48 to either the Web server 34 or the Web-AP server 38 at time T148. (Notify 278).

  Either the Web server 34 or the Web-AP server 38 supplies the “status input screen” data (Disp._DATA) 280 to the Web browser 50 and displays it at time T150. This display prompts the user to input a business situation. The user inputs what kind of situation the target requirement has changed due to the previous communication. The Web browser 50 outputs the input content (Status_IN) 282 to either the Web server 34 or the Web-AP server 38.

  Either the Web server 34 or the Web-AP server 38 generates an activation signal 284 including the transmitted “status content (Status_IN) 282”. Either the Web server 34 or the Web-AP server 38 outputs the activation signal 284 generated at time T154 to the call attempt management unit 100. The call attempt management unit 100 activates the status setting access function unit 124 using the built-in component API 136.

  The status setting access function unit 124 generates an activation signal 286 for the cooperation management unit 96. The status setting access function unit 124 outputs an activation signal 286 including “status contents” at time T156. The cooperation management unit 96 is activated in response to the activation signal 286.

  In order to transmit information (Status_IN) to the call attempt management unit 56, the cooperation management unit 96 selects any communication protocol such as SOAP and CORBA. The cooperation management unit 96 communicates with the cooperation management unit 58 existing in another domain on the network at the time T158 using the selected communication protocol (Status_IN 288).

  The cooperation management unit 58 receives “status contents” issued by the status setting access function unit 124 through communication with the cooperation management unit 96. The cooperation management unit 58 generates an activation signal 290 that activates the status setting function unit 82 in the call attempt management unit 56. The cooperation manager 58 supplies the activation signal 290 to the call attempt manager 56 at time T160.

  The status setting function unit 82 outputs an instruction to change the value of the corresponding SIP-DB 24 with the status value of the call attempt corresponding to the message at time T162 (Change 292). The SIP-DB 24 changes the status value according to the instruction. The SIP-DB 24 outputs a response signal 294 indicating completion of status setting to the status setting function unit 82 at time T164. The status setting function unit 82 receives the completion of the status setting, and generates the activation signal 294 of the cooperation management unit 58. The status setting function unit 82 outputs the activation signal 294 including the completion information described above to the cooperation management unit 58 at time T166.

  The cooperation management unit 58 receives the activation signal 296 and supplies the response signal 298 to the cooperation management unit 96 at time T168. In this supply, the cooperation management unit 58 selects and uses one communication protocol such as SOAP and CORBA to communicate with the cooperation management unit 96 in order to return the setting result to the call attempt embedding unit 100. Yes. Cooperation management unit 96 outputs response signal 300 obtained by communication at time T170 to status setting access function unit 124. The response signal 300 is a “status content” setting result issued by the status setting access function unit 124.

  The status setting access function unit 124 receives the setting result of “status contents” and returns it to one of the Web server 34 and the Web-AP server 38 as the execution result of the component API 136 at time T172 ( Response 302). Either one of the Web server 34 and the Web-AP server 38 processes into a format that can display that the status specified by the user is set. This format is, for example, a format for displaying a setting confirmation message. Either the Web server 34 or the Web-AP server 38 supplies the data (Disp._DATA) 304 processed in time T174 to the Web browser 50 as a result of “status input” at time T152. The web browser 50 displays the result of “status input”.

  Upon completion of the communication, as a continuation from the establishment of the call, a status input screen is displayed on the Web browser 50, and the situation in which the target message has changed due to the communication is input. As a result, the status of the call attempt is changed, and the user can know the change result with the web browser 50.

Next, the status change notification operation will be described with reference to FIGS. 15 and 16. FIG. First, the user related to the request uses the SIP clients 46 and 48 to send a “status change notification request (Change_REQ. 310, 312)” at times T180 and T182 to notify the status change, respectively. And sent to either the SIP-AP server 26 or the SIP server 22. In response to this, either the SIP-AP server 26 or the SIP server 22 sends the SIP clients 46 and 48 to the SIP-DB 24 as the presence notification destination of the proxy UA corresponding to the business at times T184 and T186, respectively. Register (Registration 314, 316). The SIP-DB 24 supplies the registration results (Responses 318 and 320) to either the SIP-AP server 26 or the SIP server 22 at times T188 and T190, respectively. Either of the SIP-AP server 26 and the SIP server 22 sends the registration results 322 and 324 to the SIP clients 46 and 48 as confirmation results of “status change notification request” at times T192 and T194, respectively.

  After such a notification request is made, one of the Web server 34 and the Web-AP server 38 changes the status of the business due to the status setting operation or the like. This change in situation is a change in the status of the call attempt. One of the Web server 34 and the Web-AP server 38 notifies the requesting SIP clients 46 and 48 of the status change using the presence mechanism of the corresponding proxy UA.

  When the status is changed, one of the Web server 34 and the Web-AP server 38 uses the component API 136 in the call attempt embedding unit 100 based on the status changed at time T196 to access the status change notification. An activation signal for activating the unit 126 is generated. One of the Web server 34 and the Web-AP server 38 outputs the generated activation signal 326 at time T196.

  The status change notification access function unit 126 replaces the contents of the status with the presence contents of the proxy UA, and uses the component API 134 in the service proxy UA management unit 98 to generate a start signal for starting the presence setting access function unit 110. Generate. The status change notification access function unit 126 outputs an activation signal 328 at time T198. Thereafter, the operations from time T44 to time T58 shown in FIGS. 7 and 8 are sequentially performed. However, the SIP-DB 24 notifies the change to the SIP clients 46 and 48 at times T51a and T51b, respectively. The change processing is a search processing sequence and is executed by the number of watchers asynchronously (Notify 184a and 184b).

  Thereafter, the operation continues to supply the presence setting access function unit 110 with a response signal 188 corresponding to time T58, which is a result of the presence notification. The presence setting access function unit 110 returns a response signal 330 as the execution result of the component API 134 in the service proxy UA embedding unit 98 to the status change notification access function unit 126 at time T200.

  The status change notification access function unit 126 further returns the execution result (Response 332) in the component API 136 of the call attempt embedding unit 100 to one of the Web server 34 and the Web-AP server 38 at time T202. One of the Web server 34 and the Web-AP server 38 supplies the processed execution result (Status_INF.) 334 to the Web browser 50 at time T204. The web browser 50 displays the execution result 334 supplied on the screen.

  When the status of the call attempt changes as a business situation in this way, one of the Web server 34 and the Web-AP server 38 requests a status change notification using the corresponding proxy UA presence mechanism. The status change is notified to the SIP clients 46 and 48 respectively. The call attempt status change is notified to all SIP clients requesting notification in advance. However, it is not notified to unsolicited SIP clients.

  Next, the operation of status retention notification will be described using FIG. 15 and FIG. As shown in FIG. 15, the same operation is performed from time T180 to T194. As a result of this operation, the SIP clients 46 and 48 become residence notification destinations.

  Here, one of the Web server 34 and the Web-AP server 38 monitors the status change notification access function unit 126 of the call attempt management unit 100. One of the Web server 34 and the Web-AP server 38 makes a request using the presence mechanism of the corresponding proxy UA if the status change notification access function unit 126 does not change even after a predetermined time has elapsed. Informs the SIP clients 46 and 48 of the status change. For example, the predetermined time may be set to 1 hour or the like, and may be assumed by the system for each status.

  When one of the Web server 34 and the Web-AP server 38 finds a requirement that has remained after a predetermined time, the Web server 34 or the Web-AP server 38 is a component in the call attempt management unit 100. The activation signal 340 for the status stay notification access function unit 128 is generated using the API 136. One of the Web server 34 and the Web-AP server 38 outputs the generated activation signal 340 to the status residence notification access function unit 128 at time T210. The status residence notification access function unit 128 is activated upon receiving the activation signal 340.

  The status stay notification access function unit 128 replaces the presence content of the proxy UA corresponding to the staying call attempt with a stay warning message, and generates an activation signal 342 that activates the presence setting access function unit 110. As the warning message, for example, it is preferable to use a sentence string such as “Please give immediate instructions”.

  The status residence notification access function unit 128 supplies the activation signal 342 to the service proxy UA management unit 98 at time T212. The service proxy UA management unit 98 receives the activation signal 342 and activates it using the component API 134. Thereafter, the communication system 10 sequentially operates from time T44 to T58 shown in FIG. 7 and FIG. 8, notifies the requesting SIP clients 46 and 48 of the status retention alarm, and is notified by presence. The operation is continued so that the response signal 188 corresponding to the time T58 as a result is supplied to the presence setting access function unit 110.

  The presence setting access function unit 110 returns a response signal 344 as an execution result of the component API 134 in the service proxy UA embedding unit 98 to the status residence notification access function unit 128 at time T214.

  The status residence notification access function unit 128 further returns the execution result (Response 346) in the component API 136 of the call attempt embedding unit 100 to one of the Web server 34 and the Web-AP server 38 at time T216. One of the Web server 34 and the Web-AP server 38 supplies the processed execution result (Status_INF.) 348 to the Web browser 50 at time T218. The web browser 50 displays the execution result 348 supplied to the screen.

  In this way, if the status does not change even after the predetermined time has elapsed, the Web server 34 and the Web-AP server 38 use the presence mechanism of the corresponding proxy UA to request the SIP clients 46 and 48. In each case, a status retention alarm can be notified.

  By operating as in the present embodiment, the AP constructed on the Web system 14 and the AP constructed on the SIP system 12 can be linked to each other, and construction / execution of an integrated Web / VoIP AP Operation is easily realized, and by using the call attempt embedding units 56 and 100, it is possible to realize centralized situation management from the viewpoint of achieving the objective by executing multiple communications through the communication requirements on the Web. .

  Further, it is possible to track a change in situation or stay for a long time, change the presence on the SIP-DB 24 in the SIP system 12 according to the progress situation, and notify it. As a result, since it is not necessary to hold a HTTP transaction for a long time, it is possible to easily use resources effectively and realize a user interface as a practical application.

  Next, another embodiment (first modification) of the communication system 10 to which the present invention is applied will be described with reference to FIG. The communication system 10 of this embodiment is a case where the SIP system 12 and the Web system are arranged on one computer 350. Here, with respect to the constituent elements, the same reference numerals are given to the portions common to the previous embodiment, and the description thereof is omitted. As shown in FIG. 18, the communication system 10 is connected by process cooperation on the same computer. As is apparent from this connection, the communication system 10 of this embodiment does not go through a network connection. In addition, each of the linkage management units 58 and 96 shown in FIGS. 3 and 4 is not intentionally arranged as a component, but the web accessor component 32 and the SIP accessor component 44 respectively perform linkage management in the same manner. Different systems are connected by the function call function unit 352 to be performed. For example, the function call function unit 352 may include a program using a function call of C language or C ++ language or a method call of Java (trademark) language. The operation procedure is the same as in the previous embodiment.

  Even with this configuration, it is possible to mutually link an AP built on the Web environment and an AP built on the SIP environment as in the previous embodiment. As a result, the construction, execution, and operation of a Web-VoIP integrated AP can be easily realized. Further, in this embodiment, by building a system on a single computer environment, it is possible to realize integration of Web-AP and VoIP-AP in a small computer environment.

  Next, another embodiment (second modification) of the communication system 10 to which the present invention is applied will be described with reference to FIG. 19 and FIG. In the communication system 10 of this embodiment, a SIP system 12 and an FTP (File Transfer Protocol) system 400 are connected by a network 16. Here, the SIP system 12 and the FTP system 400 are arranged on network environments belonging to different network domains. Further, the SIP system 12 and the FTP system 400 are configured to be arranged in a LAN environment in one server computer or in the same domain as in the first embodiment.

  As shown in FIG. 19, the SIP system 12 uses the same configuration as that of the first embodiment, is given the same reference numerals, and a description thereof is omitted. However, in this embodiment, the function of the accessor component in the SIP system 12 is exactly the same as that of the Web accessor component 32. However, since it is not Web-compatible and FTP, the name is FTP accessor component 402.

  The FTP system 400, which is the other system, includes an FTP server 404, an FTP database (FTP-DB) 406, an FTP application server (FTP-AP server) 408, an FTP application interface (FTP-API) 410, an FTP application (FTP- AP) 412, SIP accessor component 414 and FTP client 416. Below, each component is demonstrated easily.

The FTP server 404 is a server that handles and manages FTP. The FTP-DB 406 is a storage that stores information managed by the FTP server 404 and is a database. The information to be stored is file information transferred by FTP. The FTP-AP server 408 is a server that operates an AP that operates a file transfer protocol (FTP) managed by the FTP server 404. FTP-API 410 is an AP interface provided by FTP-AP server 408. The FTP-AP 412 is an FTP-AP that is constructed by the FTP-API 410 and operates on the FTP-AP server 408 . APs include, for example, APs such as peer-to-peer file exchange and file sharing between two parties.

  The SIP accessor component 414 is a general term for a component group (software component) in which the FTP-AP 412 cooperates with the SIP system 12. The SIP accessor component 414 is the same as the SIP accessor component 44 of the Web system 14 described above. That is, it includes a proxy UA management unit 98, a call attempt management unit 100, a cooperation management unit 96, and a component API 102. The function of each component is the same as in the first embodiment described above.

  The FTP client 416 is a client connected to the FTP server 404 and set in an environment in which the function provided by the FTP-AP 412 is used. The FTP client 416 may have a plurality of FTP client terminals 418 and 420. The FTP client terminal 418 generally has a text display screen, issues a file transfer request through this screen, and displays the file transfer result.

  With this configuration, it is possible to construct an application that provides the obtained information to a requested client regardless of different systems. That is, the AP constructed on the FTP system 400 and the AP constructed on the SIP system 12 can be linked with each other, and the construction, execution and operation of an integrated FTP and VoIP AP are easily realized. With this construction, information on each system can be shared and used smoothly. Further, by adding various components on the FTP accessor component 402 and the SIP accessor component 414, it is possible to expand the fusion type of FTP and VoIP. Along with the types of SIP-AP and FTP-AP to be implemented, various types of integrated APs of FTP and VoIP can be realized by increasing the number of components.

  Next, the status change notification operation in the communication system 10 of this embodiment will be described with reference to FIGS. 15 and 21. FIG. The status change notification is processed in the same procedure as the operation at times T180 to T194 shown in FIG. As a result, the SIP clients 46 and 48 become status change notification destinations.

  The FTP client 418 issues a “file transfer request” (Trans._REQ.) 422 at time T220. Here, the file content becomes the new status content of the call attempt. One of the FTP server 404 and the FTP-AP server 408 executes file transfer based on the received “file transfer request” 422. After this execution, one of the FTP server 404 and the FTP-AP server 408 reads the call attempt identifier for changing the status and the new status content from the transferred file content. Either the FTP server 404 or the FTP-AP server 408 generates an activation signal 424 that activates the status change notification access function unit 126. Either the FTP server 404 or the FTP-AP server 408 supplies the activation signal 424 to the call attempt management unit 100 at time T222. The activation signal 424 includes the read call attempt identifier and information on the new status content. The call attempt management unit 100 activates the status change notification access function unit 126 using the component API 136 shown in FIG.

  The status change notification access function unit 126 replaces the status content with the presence content of the proxy UA. The status change notification access function unit 126 generates an activation signal 426 for activating the presence setting access function unit 110 of the service proxy UA management unit 98 including the replaced presence content. The status change notification access function unit 126 supplies the activation signal 426 generated at time T224 to the service proxy UA management unit 98. The service proxy UA management unit 98 receives the activation signal 426 and activates the presence setting access module using the component API 134.

  Thereafter, the same processing as that from time T44 to T58 is performed in the same manner as shown in FIGS. In this embodiment, the processing from time T44 to T58 will become clearer by replacing the Web with FTP. Thereafter, the operation continues from time T226 to T230 based on the result of notification by presence.

  The presence setting access function unit 110 returns the status notification result (Response) to the status change notification access function unit 126 as the execution result of the component API 134 at time T226. The status change notification access function unit 126 returns a status notification result (Response) 430 to either the FTP server 404 or the FTP-AP server 408 as the execution result of the component API 136 at time T228. Either the FTP server 404 or the FTP-AP server 408 processes the status notification result into a format that can be displayed by the FTP client terminal. The displayable format includes, for example, a SIP-URI format. The FTP server 404 and the FTP-AP server 408 supply the data (Status_INF) 432 processed at time T230 to the FTP client terminal 418 that made the “file transfer request”. The FTP client terminal 418 displays the result of “file transfer request”.

  By operating in this way, the file transfer from the FTP client terminal 418 is handled as an identifier of the call attempt that changes the status of the file content and the new status content, and the status of the call attempt changes due to the file update by file transfer. One of the FTP server 404 and the FTP-AP server 408 can notify the requesting SIP clients 46 and 48 of the status change using the presence mechanism of the corresponding proxy UA, and the processing result Is displayed on the FTP client terminal 418, the user can know the result of the status change processing.

  However, it goes without saying that the status change of the call attempt is notified only to all SIP clients that have requested notification in advance.

  In this way, the AP constructed on the FTP system 400 and the AP constructed on the SIP system 12 can be linked to each other, and the construction, execution and operation of an integrated FTP and VoIP AP can be realized easily. become. In this embodiment, by adding various components on the FTP accessor component 402 and the SIP accessor component 414, it is possible to expand the combined type of FTP and VoIP. In addition to the two types of SIP-AP 30 and FTP-AP 412 to be implemented, by increasing the types of these components, various FTP-VoIP integrated APs can be realized. In this embodiment, the procedure of status change notification has been described. However, the present invention is not limited to this example, and it is needless to say that other access functions of the call attempt management unit 100 can be realized.

  Fusion is not limited to VoIP-AP (SIP-AP) and Web-AP or VoIP-AP (SIP-AP) and FTP-AP, but can be applied to fusion between various different protocols. Is possible.

  With the configuration described above, when a request from the web browser 50 connected to the web system 14 is executed as a call attempt, the call attempt management unit 100 for the request is started using the HTTP protocol, and the cooperation management unit 96 The request is converted to a SOAP / CORBA protocol request and sent to the linkage management unit 58. The linkage management unit 58 makes a request for the SIP communication protocol, the call attempt management unit 56 processes the request, and the response of the processing result is called. It is sent to the Web browser 50 requested via the attempt management unit 56, the linkage management unit 58, the linkage management unit 96, and the call attent management unit 100, and is displayed. And the service surrogate UA management unit 54 are operated in order and registered, and the registration results are returned to the Web system 14 in the reverse order. By establishing a call that corresponds to the calling instance between multiple communication protocols, centralized status management can be achieved from the viewpoint of achieving the objective, and there is no need to hold HTTP transactions for a long time. User interface as a practical application can be easily realized.

  The call attempt management unit 56 includes functions for generating, deleting, information editing and information retrieval, and status search, setting, change notification, and status residence notification corresponding to an instance of a call. 100 includes functions for accessing each of the call attempt management units 56, so that the status until the message is completed can be managed from the Web, for example.

  By using either SOAP or CORBA as a protocol that can be handled in common for the SIP and HTTP protocols and the SIP and FTP protocols, information can be communicated even between systems in different system environments.

  The communication system 10 can reduce the system configuration by accommodating the SIP system 12 and the Web system 14 in the same computer. In addition, by providing the functions of the cooperation management units 58 and 96 in a predetermined function call, it is not necessary to mount the cooperation management units 58 and 96 as respective components, which contributes to downsizing of the apparatus. By interposing a network between the SIP system 12 and the Web system 14 or the SIP system 12 and the FTP system 400, each system can be distributed and the communication system 10 can be arranged flexibly. Can do.

  The SIP system 12 and the Web system 14, and the SIP system 12 and the FTP system 400 are respectively configured by computers, and programs for causing the communication system 10 to function are a service proxy UA management unit 54, a call attempt management unit 56, and a cooperation management unit 58. In addition, by functioning as the service proxy UA management unit 98, the call attempt management unit 100, and the linkage management unit 96, the system configuration can be further reduced in size, in response to requests for additions, reductions, version upgrades, etc. However, it can respond flexibly.

  Further, according to the service providing method of the present invention, the activation signals 236 and 238 including the status are sequentially generated according to the call attempt and the status according to the requirement selected from the contact list in the Web system 14, and the linkage management is performed. The processes (third and fourth steps) are executed in sequence, the activation signal 242 is generated in the SIP system 12, information processing is performed corresponding to the function activated by the activation signal 242, and response information 246 for this information processing is displayed. The activation signal 248 is generated, the response information 246 is returned to the Web browser 50 in the Web system 14 through the cooperation management process, and the Web system 14 accesses the proxy user agent of the service proxy UA management unit 54 in the SIP system 12. After registering the information about the business and notifying the Web system 14 of the completion of registration, the SIP system 12 is started by starting the SIP system 12 from the Web system 14. By establishing communication between SIP clients 46 and 48 in this way, it is possible to implement communication process management type APs by executing requests from the Web, and there is no need to hold HTTP transactions for a long time. Resources can be used effectively.

  The service provision method supplies the status change from the SIP system 12 to the Web system 14 upon completion of communication, starts the function to access the call attempt status setting in the Web system 14, and performs SIP through the linkage management process. After the call attempt status setting function in the system 12 is started and this status is changed, the response signal 294 of this change is supplied to the Web system 14 through the linkage management process, and the change response signal 294 is sent to the Web of the Web system 14 By sending it to the browser 50 and displaying it, it is possible to know the status change of the SIP client on the Web.

  In addition, the service providing method activates either the function of notifying the change of the status of the call attempt in the SIP system 12 or the function of accessing the notification of the change of the status of the call attempt in the Web system 14 according to the change of the status. In addition, in response to the activation, the presence setting function in the proxy UA and the access function to the presence setting function are activated, and the status is changed to the SIP clients 46 and 48 requested in advance to connect to the SIP system 12. You can be notified of status changes on the Web screen.

  Further, the service providing method has a function of notifying the stay of the call attempt status in the SIP system and the function of accessing the stay notification of the call attempt status in the second system when the status remains the same even after a predetermined time has elapsed. In response to this activation, the SIP client requested in advance to connect to the SIP system 12 by activating the presence setting function in the proxy UA and the access function to the presence setting function in response to the activation. Notifying 46 and 48 of the status change can prompt prompt action.

  Call Attempt has functions to create, delete, edit and search information for calling instances of clients connected in the SIP system 12, and to perform status search, setting, change notification, and status notification according to status status retention. It is possible to easily realize a user interface as a practical application by operating according to requirements and allowing the Web system 14 to access the functions of the SIP system 12 according to requirements. .

  By using either SOAP or CORBA as a protocol that can be handled in common for the SIP and HTTP protocols and the SIP and FTP protocols, information can be communicated even between systems in different system environments.
