METHOD AND DEVICE FOR TREATING CALLS IN DURING AN INTERNET SESSION OF A USER OF A MOBILE RADIO DEVICE VIA A CELLULAR MOBILE NETWORK

As is known to the person skilled in the art, there are class A and class B mobile radio terminals (cell phones) in 2G network radio networks. If, during an Internet session of a user of a mobile radio terminal via a cellular mobile radio network (2G mobile radio network, 3G mobile radio network, etc.), a call from a third party arrives for this mobile radio terminal in the mobile radio network, the mobile terminal can classify the Internet service in parallel with Class A mobile radio terminals Process voice connection call, i.e. continue the internet session and answer the voice connection call in parallel (i.e. make a voice connection with the calling subscriber), while for class

B mobile terminals during an open PDP context (i.e. during an internet session) a voice connection cannot be set up in parallel to the packet switching, so that incoming voice connections and calls are forwarded to the voice connection calls if call forwarding unconditional = CFU for this mobile terminal ) has been activated or, if unconditional call forwarding has not been activated, the incoming voice call is connected to the mobile radio terminal and the internet session is either interrupted or ended. Even if the internet session is only interrupted and, for example, the user has almost filled out an extensive form during an internet session and a voice connection call arrives, the internet session will be interrupted, however, if, for example, he drives through a tunnel in a train or car or if he enters a tunnel There is a radio hole etc. during the voice connection, not only the voice connection but also the internet session is frequently interrupted.

The object of the present invention is for mobile radio terminals which do not have a parallel

Internet session and a voice connection can allow to allow that during an Internet session for the mobile terminal in the mobile network incoming voice connection calls are handled more efficiently. The object is achieved in each case by the subject matter of the independent claims.

According to the invention, when voice connection calls arriving during an internet session for a user of a mobile radio terminal are not forwarded to the mobile radio terminal, but to the mobile radio terminal under

Maintaining the internet session (without interruption of the internet session) options for handling the incoming call are offered and the incoming call is handled according to the selection from the options, is the treatment of those arriving during an internet session

Voice connection calls are possible much more efficiently than was previously possible with such mobile terminals.

The invention can be implemented in particular in IN / Camel mobile radio networks via a control device (SCP) or in mobile radio networks with an API interface to third-party applications (third-party applications).

Further features and advantages of the invention result from the claims and the following description of an exemplary embodiment with reference to the drawing. It shows

Figure 1 schematically shows a possible implementation of the

Invention.

FIG. 1 shows a mobile radio terminal 21 of the mobile radio terminal class “B ^w (with the Mobile terminal number 0171 5040302 (reference number 22)) of the mobile terminal user 23. The mobile terminal 21 requests in step 1 (Activate PDP context = request to activate PDP context) via a (packet-switched) air interface 24 to a mobile radio network at a switching device 25 to activate a PDP Context to start an internet session. The exchange SGSN 25 requests in step 2 (InitialDGprs) for the mobile radio terminal 21 with the mobile radio terminal number 22 from a GPRS service facility 26, an SCP 27 and GPRS context data, which the GPRS facility 26 in step 3 (ConGprs) and the SGSN 25 sends back which data for establishing a PDP tunnel in step 4 (Activate PDP Context Response = response to activate PDP context) is transmitted to the mobile station 21. The mobile station 21 can thus conduct an internet session via the air interface 24 of the mobile radio network 25, 26 USW.

If, during the internet session of the mobile terminal 21, a call 5 (0: IAM (CDPA = 01715040302)) from a subscriber 26a of a mobile network or fixed network for the mobile terminal 21 arrives at a switching center MSC 27 of the mobile network during the internet session via the air interface of the cellular mobile radio network, requests this in step 6 (SRI (01715040302)) at a home location register HLR of the mobile radio terminal 21 for data necessary to establish a call to the mobile radio terminal (current VLR of the mobile radio terminal or IN data, as well as subscription data for GPRS and / or Camel or other services), which reports the home location register 28 in step 7 (SRI_RES (T_CSI)) to the switching center 27. The switching center transmits data relating to the desired voice connection call setup in step 8 (InitialDP (TDP12, MSISDN)) to a service control device SCP 27, whose camel service logic 29 in step 9 (request IP-Add =?) the current for an internet session used by the Cellular terminal 21 is queried by a GPRS service logic 26, which returns this IP address in step 10 (answer IP addr. = Xxx) if this cellular terminal is currently carrying out an Internet session via this IP address (or if no Internet session is being carried out, a new one is performed) Assigns IP address). The camel service logic 29 transfers to the GPRS service logic 26 in step 11 (push page = page transmitted using the push method) a page 30 transmitted in a push service to the mobile radio terminal 21, which is to be displayed there as a file, which in step 12 ( suspend call establishment / play announcement = interrupt connection establishment / import announcement and push the sevice page = transmit service side) transmits the GPRS service logic to the mobile radio terminal (via an air interface 24 of the mobile radio network) for display there. On the part of the mobile radio terminal 21, the treatment options are presented as a window in the display of the mobile radio terminal or, for example, acoustically or in another way to the mobile radio terminal user 23 for selection, for example the possibility of interrupting / postponing the

Internet session (close session / interrupt session), the possibility of rejecting the incoming

Voice connection call (reject call), the possibility of forwarding the incoming voice call to a number (e.g. answering machine) and possibly others

Possibilities. An entry of the mobile terminal user 23 into the mobile terminal 21 regarding its selection from the options 31-33 (31: close session = end Internet session, 32: reject call = reject voice call, 33: forward call to ... = voice call to a predetermined number .. . forward) is passed on in step 13 (return service page, close session = end of session, end session) to the GPRS service logic 26 in SCP 27, which informs the selection in step 14 (establish call = connection establishment) of the Camel service logic , for example the selection that the Internet session should be interrupted or ended and the voice connection from the caller 26 to the user 23 to be switched through. The camel service logic then gives the instruction for further call establishment (continue = continue connection establishment) to the switching center MSC 27 in step 15, which continues to establish the call in step 16 (Continue / Disconnect announcement / Establish the call = continue handling / announcement / Establish connection) and any queue display interrupts.

Alternatively, the method can also be carried out via an API interface from the mobile radio network to third party applications. In this case, when a subscriber 23 opens an internet session with his mobile radio terminal 21, a message is transmitted to an application server (application server) and the IP address of the internet session of the mobile radio terminal is stored there. An unconditional call forwarding of the subscriber is then activated, for example by the application server sending a message to a home location register. Every incoming voice connection call for a mobile radio terminal is (for

Mobile devices for which this service is activated) if the mobile device is in an Internet session forwarded to a service number. The service number is analyzed during forwarding and the application server is informed via the API interface that a voice call arrives during an internet session. The application server sends a file which enables a selection of possible options on the mobile radio terminal side (popup window etc.) to the mobile radio terminal and initiates it in accordance with that transmitted by the mobile radio terminal

Response of the subscriber a treatment of the incoming voice connection call by instructing the cellular network via the API interface whether it is the

Forward a voice connection call, for example, connect to the user of the terminal or reject the call.
