Referring now to Fig. 5 illustrating the operation of the HLR configuration component 50 of Fig. 4. Fig. 5 illustrates the operational steps performed by component 50 of Fig. 4 in order to appropriately configure the Home Location Register (HLR) 27 of Fig. 2.
  • HLR Home Location Register
  • the necessary configuration process is performed in order to provide to subscribers the option of utilizing voice services integrated into a convention data session.
  • Configuring the HLR configuration involves the activation of a specifically developed program product.
  • the program product accepts subscriber-specific input from an external source and applies updates the associated subscribers' records within the HLR.
  • the configuration procedure is typically performed offline and involves manual input by the administrator of the system.
  • the identification of a subscriber such as the cellular phone number thereof is obtained.
  • the HLR database is opened and at step 156 the subscriber's record, indexed by the subscriber's identification, is obtained from the HLR database.
  • a subscriber's HLR record is structured such that specific control fields defining specific subscriber options are given different values.
  • the values are indicative of the provision of specific network operator supplied services to the subscriber.
  • One of the control fields is operative in providing the subscriber with the call waiting service.
  • the field is set to a specific value the calls made during a period in which the subscriber's device is busy with an another call are diverted to a call-waiting switch to be handled thereby appropriately. Such handling could involve indication to the called party that a call is waiting, or providing the caller with the option of recording a voice message.
  • This call divert field is utilized at step 158.
  • the program will effect the insertion of an additional control value to the field, which will be operative in providing the subscriber with the option of using voice services within a data session.
  • the record will be written back to the database.
  • Fig. 6 that illustrates the operation of the Subscriber Parameters Handling Component 52 of Fig. 4.
  • Network access service providers typically assign a unique number for each subscriber.
  • the mobile subscriber is identified in different manner.
  • the subscriber is typically identified by the Mobile Subscriber ISDN (MSISDN) number.
  • MSISDN Mobile Subscriber ISDN
  • MSISDN is used for call related requests and it is visible to both the caller and the subscriber as the dialed number.
  • requests from the network will be based on MSISDN.
  • the subscriber can be also identified by other identification means, such as the International Mobile Subscriber Identity (IMSI) number, which is typically used in the Global Standard for Mobile cornmunication (GSM) cellular systems.
  • IMSI International Mobile Subscriber Identity
  • GSM Global Standard for Mobile cornmunication
  • the IMSI is held in the subscriber identity module (SIM) of the mobile station, typically on a "SIM card” that is inserted inside all GSM wireless devices in order to identify the subscriber to the GSM network.
  • SIM subscriber identity module
  • the ISMI is not visible or accessible to the subscriber.
  • Each data session is assigned a unique ID by the network access service provider.
  • the DVS server 38 retrieves the unique session ID by utilizing the subscriber's identification number such as a MSISDN number as a key (step 60).
  • the DVS 38 by using the standard Remote Authentication Dial-In User Service (RADIUS) protocol interfaces to a RADIUS server in order to obtain the subscriber's parameter values.
  • RADIUS is an authentication and accounting system used by many service providers. When a subscriber dials in to a service provider the user typically enters the username and the password thereof. The information is passed to a RADIUS server, which checks that the information is correct, and then authorizes access to the system. The information is also stored on the RADIUS server for the duration of a session.
  • the DVS retrieves the stored values from the RADIUS server by indexing the current session identification value into the RADIUS database.
  • the parameters thus obtained include the subscriber's IP address, the subscriber's user-name, and the password thereof.
  • the information is stored in the database of the DVS server 38 (at step 64) to be used after the completion of the voice service for the resumption of the suspended data session.
  • the DVS could retrieve and store the subscriber information form the network access service provider independently of the RADIUS server or the DVS could assign a specific session identification to be connected to the unique session identification allocated by the network access service provider.
  • Fig. 7 is the method for intercepting voice service-related requests transmitted by a service provider.
  • the method is utilizing a TCP/IP socket or an endpoint in a connection to be functionally receptive to a request from the service provider over a TCP/IP connection (step 70).
  • the socket is created and used by utilizing a known set of programming requests or socket APIs. In other embodiments of the present invention other connection methods could be used .For example, the UNIX C sockets could be utilized.
  • the method performs a check regarding the interception of a request from the voice service provider. If no request was intercepted then the method's control effects a return to step 70 in order to wait for further incoming requests.
  • the intercepted request is validated.
  • the validation process checks the subscriber's identification and the introduced password in order to determine whether the request's origin is known to the system. If the request is valid at step 78 the request is formatted to a structure suitable for insertion to a memory device. Additional information such as the service type and control data is attached to the formatted record.
  • the request is inserted into a dynamic memory device, such as a buffer, ready for processing by the request handler component.
  • Figure 8 shows the operation of the request handling component 56 of Fig. 4.
  • the request handler component retrieves an intercepted, validated, and formatted request from the dynamic memory device, such as a buffer.
  • the request handler transmits a command to the gateway servlet associated with the WAP gateway to suspend the currently managed data session.
  • the WAP gateway server suspends the session and notifies the handler of the event by transmitting a confirmation message to the DVS 38.
  • the suspension of the data session does not terminate the session allowing a voice session to be initiated and conducted at the same time as the session data is pending.
  • the handler instructs the network access service provider switch 26 to sub-address the call to the voice server 36.
  • the switch sub-addresses the call to the voice server 36 and sends confirmation to the handler.
  • voice server 36 opens a voice channel and a virtual data channel to the subscriber 10,12,14.
  • Opening of the voice channel while the data channel is suspended enables the gateway server 30 to later resume the data channel automatically and without need for the subscriber to initiate a new request for a data channel.
  • the requested voice service is performed by the voice server subsequent to the appropriate command sent by the handler to the voice server 36.
  • Fig. 9 illustrates the operation of the data session resumption component 58 of Fig. 4. Subsequent to the completion of the voice service the previously suspended data session is restarted by the Data Session Resumption component 58 of Fig. 4.
  • the previously saved session and subscriber parameter values are read from the storage. The component sub-addresses the call to the RAS at step 94.
  • the stored subscriber identification is retrieved from the RADIUS server and at step 98 a command is sent to the gateway servlet associated with the gateway server to resume the data session. The gateway server resumes the session and provides the subscriber with the option of continuing the previously suspended Web navigation.
