TR201515919A2 - A SYSTEM THAT PROVIDES CALL ROUTING PREVENTION - Google Patents

Abstract

The present invention relates to a system (1) that automatically activates call forwarding for call setup requests from caller numbers with predetermined prefixes.

Description

The number calling from the party requesting the call setup in the description, the call The scanned number that the initiator wants to call is sent to the call recipient himself. The party to which the incoming calls are forwarded will be referred to as the forwarding number.

Call setup from caller nuinaras with prefixed prefix automatic call forwarding that is active for system (1), which is the subject of the invention, which prevents it; within a mobile network, from within the mobile operator or from the mobile Call setup for calls that are wanted to be set up from outside the operator the requested caller, which is included in the request of the received call institution, enabling the receipt of at least one that determines whether the call forwarding feature of the number is active or not. switchboard (2), call setup from caller nuinaras with prefixed prefix call routing for calls to be established in line with the demands of at least one database (3), in which the rules for blocking Call forwarding feature in communication with the exchange (2) and the database (3) for active dialed numbers, at least to the incoming and calling number in it. and the call setup request, which includes information about the call number. receiving the message containing the information from the exchange (2), data about the prefix of the calling number in line with the information checks whether the forwarding blocking rule exists in its base (3), Forwarding blocking related to the prefix of the caller number in the database (3) If the rule is included, the call setup request from the said caller number. depending on the information that the call should be set to the forwarding number. the owner's message; related to the prefix of the caller number in the database (3) if there is a forwarding blocking rule, the incoming call from the said caller number Depending on the call setup request, the call's forwarding number is determined. message that has information that the forwarding should be prevented includes at least one call routing control unit (4) that sends it to the exchange (2).

The switchboard (2) in the system (1), which is the subject of the invention, is located within a mobile network. from within the mobile operator or from outside the mobile operator. receives call setup requests for the calls to be set up. Meet The switchboard (2) in the system (1) in question, for example, from the mobile operator. A mobile switching center (MSC_Mobile) that receives call setup requests Switching Center) or call setup from outside the mobile operator is the gateway mobile switching center (GMSCýGateway Mobile Switching Center). To be set up to the dialed number itself in the switchboard (2) If there is a request to divert the requested call to another number, The subject request is recorded with the dialed number and forwarding number information. are held. Call setup from the caller (2) from the caller from the dialed number information in the requests of the dialed number itself. Indicates whether it gives a forwarding request for calls. Wanted If the number does not have any forwarding instructions, the exchange (2) is the caller. the number dialed by the caller number upon the call setup request from the number makes a call between A predetermined number of the dialed number If there is any forwarding instruction to the forwarding number, the exchange (2) call setup with at least the caller number and the dialed number information sends a message containing the request information to the routing control unit (4).

In the preferred embodiment of the invention, the call from the caller from the central (2) upon installation request CAP lDP (CAMEL Application Part IIItial Detection Point_Customized Applications for Mobile Networks Application Part First Determine Point) message and sends the message in question to the forwarding control. sends it to the unit (4).

The database (3) routing control unit (4) in the system (1) which is the subject of the invention. in communication with. The prefix specified in the database (3) It will be set up in line with call setup requests from caller numbers that have Register rules for blocking call forwarding for calls with is kept under. In the database (3), for example, used in Turkey with the prefix of 850, which is owned by the corporate lines independent of the city Rule of preventing forwarding in calls from numbers is under record are held.

Call forwarding control unit (4) in the system (1) which is the subject of the invention; central (2) and the database (3). Call forwarding controller (4) receives the message containing the call setup request information from the exchange (2). Call routing control unit (4) is the caller in the message in question. connects to the database (3) using the number information and the database (3) the call with the prefix of the caller number information in question. whether any rules regarding the blocking of redirects are registered. He questions whether it is. As a result of the query process, in the database (3) If no rule is reached, the call routing control unit (4) Depending on the call setup request from the number, the forwarding of the call send the message that has the information that it should be installed to the switchboard (2). is sending. As a result of the query process, the caller in the database (3) regarding blocking of forwarding depending on the prefix the number has if a rule is reached, the call forwarding control unit (4) Depending on the call setup request, the call's forwarding number is determined. message that has information that forwarding should be prevented sends it to the switchboard (2). In the preferred embodiment of the invention, the call routing control unit (4) accepts the call initiated from the caller number of the exchange (2). to set directly to the dialed number instead of the forwarding number. routing control unit (4), CAP IDP (CAMEL) coming to it from the exchange (2) Application Part Initial Detection Point_Mobi1 Customized For Networks Applications Application Partition Initial Locate) message forwarding number information is determined by the mobile operator beforehand. CAP CONNECT (CAMEL Application) by equating to high number of routings Part C0nnect_M0bil Applications Customized for Networks Application Part connect) message and sends this message to the exchange (2).

The system (l), which is the subject of the invention, located outside the mobile operator and in the database (3) a caller with a prefix whose call forwarding blocking rule is registered a caller who has previously instructed the call forwarding from the number to the exchange (2). Below is an example scenario that assumes a call to a number is initiated. will be mentioned. In the application in question, the call from the first caller After the installation instruction, the exchange (2) in its most basic form, the caller number information, CAP IDP message containing dialed number information and forwarding number information manufactures. Thereupon, the exchange (2) calls the CAP IDP message in question. It transmits it to the control unit (4) on its direction. Call forwarding control unit (4) to the caller number information in the CAP IDP message from the exchange (2). performed in the database (3) by accessing and connecting to the database (3). As a result of the query process, the call related to the caller number prefix reaches the rule of blocking the redirect. Call forwarding control unit (4) followed by the forwarding number in the CAP IDP message the highest forwarding information previously determined by the mobile operator. It creates a CAP CONNECT message by equating to the number of sends the CAP CONNECT message to the exchange (2). at the power plant (2) in the CAP CONNECT message from the call routing control unit (4). from the forwarding number information to the specified forwarding number of the call. prevents redirection.

Around these basic concepts, the subject of the invention is “Call Forwarding Various applications related to "A System That Provides Prevention (1)" development is possible and the invention cannot be limited to the examples described herein. essentially as specified in the claims.
