Definitions

  • the present invention relates to wireless application protocol (WAP) technologies, and more particularly, to a method for providing a response to a request by a wireless client from a server after timeout of the request.
  • WAP wireless application protocol
  • the ability to transmit data to a client from a server without the client actually requesting the data is referred to as "push” technology.
  • the Internet is based upon “pull” technology wherein a client browser must request a web page before it is transmitted to the client.
  • Broadcast media utilizes push technology to transmit information to everyone regardless of whether or not anyone is connected.
  • the present invention overcomes the foregoing and other problems with a method for processing a request from a mobile terminal wherein the request requires a period of time exceeding the request timeout period.
  • the request Upon receipt of the request for a selected action from the mobile terminal at a WAP server, the request is processed for the selected action.
  • an indication is provided to the mobile terminal to notify the mobile ter mal that the request is being processed. The indication is provided during the entire processing period of the requested selected action.
  • the mobile terminal is notified of completion of the processing and provided the request results.
  • FIGURE 1 is a block diagram of a WAP client interconnected with a WAP server via a WAP network;
  • FIGURE 2 is a signaling diagram illustrating the method of the present invention.
  • FIGURE 1 there is illustrated a WAP client 12 interconnected with a WAP server 15 via a WAP network.
  • the WAP client 12 interconnected with a WAP server 15 via a WAP network.
  • the WAP gateway server 25 comprises a protocol gateway which translates requests from a WAP protocol (WSP, WTP, WTLS and WDP) to a WWW protocol (HTTP and TCP/IP). This is accomplished via content encoders and decoders 35 within the WAP gateway server 25.
  • WSP WAP protocol
  • WTP WTP
  • WTLS WTP
  • WDP WWW protocol
  • HTTP and TCP/IP content encoders and decoders 35 within the WAP gateway server 25.
  • FIGURE 2 there is illustrated the manner in which amobile terminal 10 may provide a request to a web server 15 wherein processing of the request requires more than the timeout period associated with a request in a WAP server 15.
  • the mobile terminal 10 transmits a request 45 to a web server 15 via the WAP gateway 25.
  • This request may comprise a request for tickets, stock quotes, account balance, etc.
  • the web server 15 responds by accessing a WAP application 30 associated with the web server 15 which is capable of providing the necessary response to the request 45.
  • the WAP application 30 within the web server 15 writes at 60 a temporary record to a database 35 for containing the request result.
  • the application 30 requests a process 40 to perform the requested action at 65.
  • the application 30 also generates at 65 a WML page indicating that the user should wait while the request is being processed.
  • the WML page generated at 65 is transmitted back to the mobile terminal 10 at 70.
  • Responsive to the loading of the WML page after a predetermined time interval (for example, 5 seconds), a request for the same WML page is generated at 65 and transmitted at 85 back to the WAP application 30 from the mobile terminal 10.
  • the WAP application 30 responds to the request by checking with the database 35 at 100 to determine if the request processing is complete. If the processing is not complete, the WML page is transmitted back to the mobile terminal 10 at 105.
  • the process may repeat at 110 to continue reloading of the WML page from the WAP application 30 to the mobile terminal 10 until the processing of the request is completed.
  • the results 115 of the request are written from the process 40 to the database 35.
  • the WAP application 30 accesses the database 35 at 130 and discovers that the request processing has been completed.
  • the WAP application 30 extracts the results 135 from the database 35 and transmits the results to the mobile terminal 10 at 140.
  • the WML code for the WML page downloaded to the mobile terminal lOisgenerated dynamically using servlet, JSP, ASP, CGI or associated technology.
  • This method will overcome current deficiencies in the WAP standard which may hinder a developer who wishes to perform functions that take longer than the standard request timeout period. Using this method, applications may be developed which require greater than the standard request timeout period necessary to process a request thus providing greater functionality to the user.

Abstract

La présente invention concerne un procédé permettant de traiter une requête issue d'un terminal mobile, ladite requête nécessitant un temps de traitement supérieur à une période de temporisation de requête. Une requête issue d'un terminal mobile, concernant une action choisie, est reçue au niveau d'un serveur WAP, puis est traitée par rapport à l'action choisie. Lors du traitement de ladite requête, une indication informe le terminal mobile que la requête est en train d'être traitée. Lorsque la requête est exécutée, le terminal mobile est informé de l'exécution du traitement de l'action requise.
