117231 Arrangement for implementing a blocking service - Arangemang för att verkligas ett fördindringsservice

The present invention relates to communication. More particularly, the present invention relates to the prevention of the receipt of unidentified calls / calls on a mobile network.

Mobile network refers to a telecommunications network to which terminals can connect via a wireless connection. Typically, however, a mobile network refers to a public land mobile network (PLMN), in which signaling between network elements 10 uses the Mobile Application Protocol (MAP). PLMN networks, e.g. GSM, CDMA, WCDMA, GPRS, EDGE, UMTS networks and similar 2nd and 3rd generation cellular networks are in themselves quite detailed standardized and defined, and are therefore structurally and functionally prior to the skilled artisan. it will be appreciated that PLMNs are not specifically addressed herein unless there is a specific need for understanding the present invention.

There is a prior art known "terminal handset" procedure (= customer rejects the call directly by pressing the end call key) or a simple "" missed call "procedure. These principles have so far been the user's only ability not to receive unidentified invitations / calls. In particular, the development of mobile communication is characterized by the fact that first, various communication-serving φ solutions are implemented as terminal features and can then eventually become user-friendly mobile verco features of the terminal *****, ···, such as the VLR register ( VLR, * ·.:. Visitor Location Register) and / or HLR (Home Location Register) · 1 ·, 25 features or services.

♦ · ** 1 "Red handset" or "" not answering "menu are both incomplete and not aa1 ·. ·· 1, implement call barring on the mobile network. To date, device vendors have not implemented a · a 1 · mobile network solution to implement ACR (Anonymous Call Rejection), or * a · · I β: 30 unrecognized call / call barring service. There are many reasons for this, but one of the most important reasons may be that the message required by the ACR service * is not taken into account in the MAP (Mobile Application Protocol) signaling (MAP) ..1 · 1 used in the mobile network. It is also noteworthy that implementing an ACR service or executing solution 117231 2 alone as an operator solution can be so costly for the operator and time-consuming that the investment is no longer profitable. Unlike the standardization of MAP signaling, the terminal standardization included the principle from the beginning. However, the problem is that the terminal does not respond when an unidentified call arrives, and in addition, it is impossible to distinguish between unencrypted or unencrypted numbers encoded by the calling client interface, since this cannot be detected in signaling.

Additional legislation for implementing unidentified call / call barring is also exerted by 10 legislation EC Directives, including: - Act on Privacy and Telecommunication Protection (22.4.1999), §§ 14 ... 17; - Regulation on privacy and telecommunications security (11.6.1999), § 3; 15 - Directive 2002/58 / EC of the European Parliament and of the Council concerning the processing of personal data and the protection of privacy in the electronic communications sector (Directive on privacy in electronic communications), Article 8.

It is a general object of the present invention to provide a mobile network client in an operator-maintained 20 mobile network with a new and inventive arrangement for implementing a blocking service that can prevent blocking of an unrecognized paging instruction. called customer interface. By using such a blocking service, the customer now has a * * »• * ·. * * *. the ability to place their customer interface in a state where the customer interface will not be ·· ·.:. invitations where the caller's identity is secret.

According to a preferred embodiment of the invention, a preferred disadvantage is. makes it possible for the mobile network to be able to state that the • · * ·. ···. the client interface includes an active blocking service, especially so that the HLR register could. \ express to the MSC or MSC / VLR (Mobile Switching Center) of the mobile network, * * · 30 that the called client interface is associated with and is an active blocking service.

• · • · ··

In order to implement the "blocked mobile network blocking service" according to the present invention for mobile network client interfaces, the mobile network 117231 3 recognizes that the called client interface includes blocking services, and that signaling (CAP, Camel Application Part - GSM 09.78) to the mobile network exchange for the existence of a message blocking service, particularly advantageous, blocking loop 5 is an ACR service, which is an intelligent network or IN service based on the logic of an IN network.

In one embodiment of the invention, the existence of the blocking service associated with the client interface is registered in the client interface client $ - / service information in the HLR register. Information on the existence of a blocking, preferably ACR, service can be signaled to signal calls / calls to the VLR register as well.

It is advantageous for the present invention that the MSC or MSC / VLR center of the mobile network recognize the blocking or ACR service associated with the client interface by the HLR register providing it with a CAP signaling message, e.g., Camel, T-CSI, , or end-call trigger information, from the ACR service for that client interface. This avoids the lack of a MAP message suitable for implementing the blocking, or ACR, service.

As a result of triggering the blocking or ACR service existence information 20, the control of the incoming call is transferred to the intelligent network (IN) logic, which processes the incoming call a ·,, ·, case by case. Then the IN logic can e.g.

• «t ♦ ♦. - reject the invitation, »· · e» ·. ···. - informs the caller that "the number you are calling does not accept invitations / calls where ·· * is blocked", e «« **. ···. 25 - inform the caller that '' the called subscriber is not answering ', • ψ transfer the invitation / call to the answering machine, - continue to connect.

i. · * ·. The owner / holder of the client interface can also, through their own settings, influence the IN logic and thus the subsequent processing of the incoming invitation.

e · · - · 30 · + * • * 7 The blocking or ACR service according to the present invention is based on the idea., 1; * implements the ACR service based on fixed telecommunications network standards and on the capability of the intelligent network or *:: IN system. intervene in the control of an invitation to a client interface. Preferably, the ACR service according to the invention is integrated in the operator's own telecommunication network and / or its other services in a cost-effective manner by the operator's own methods. In this way, the blocking or ACR service can be implemented from other parties, i.e. for example, independent of equipment vendors and standardization. When the operator performs the blocking, preferably the ACR service 5 itself, with its own methods and systems, the ACR service can be made available to the mobile network client interface regardless of the equipment vendor and signaling standardization schedules.

With the intelligent network solution of the blocking service according to the invention, it is possible to filter out the unidentified calls and perform the actions requested by the client interface, such as transfer to the voicemail, communication or some other action.

Regulatory requirements based on legislation and / or directives may always require new functionalities, which may be expensive for the operator and 15 for the telecommunications network user. The public authority may also charge a free telecommunications service, so the investment should be kept to a minimum. In any case, the arrangement of the present invention can completely avoid external cost pressures.

•. The invention will now be described, by way of example, by means of a preferred embodiment of the implementation of the ACR service in a mobile network, with reference to the accompanying drawings, in which: · · ·, ··· \ FIG. 1 illustrates schematically the general principle of an ACR- * service according to an embodiment of the present invention.

* ::: 25 ♦ ♦

Referring to Figure 1, which illustrates by way of example the basic principle of operation of the ACR service according to the invention. The example layout shown in Figure 1 includes "* lu - calling customer interface A, which is a fixed telecommunication network 1 customer interface, * e * · [- calling or local exchange 11, * ♦ * ·" · 30 - calling customer interface B, which is mobile - i.e., a PLMN network 2 client interface, which is connected to a * * ***** wireless interface to a cellular network base station system 21 to which a subscriber line B is located within the coverage area of the * 1 * belonging base station, * · 117231 5 - to form a service area includes at least one but usually a plurality of base station subsystems S 21, at least one MSC or MSC / VLR exchange 22, optionally an independent VLR register 23, and HLR register 24, and a GMSC gateway exchange through which mobile network 2 communicates with other telecommunications networks, 5 and - at least an IN network 3 which, in the example embodiment, is directly connected to or communicating with the MSC / VLR exchange 22 of the mobile network 2, which the area has a base station subsystem 21 connected to a B called over a wireless subscriber, which in the exemplary discussion is called subscriber A of the fixed network 1 in addition to the MSC / VLR-10 and / or alternatively the IN network can also connect to the MSC in the mobile network (not shown in Figure 1).

According to the basic idea of the present invention, the MSC, MSC / VLR or GMSC switching center 22 of the mobile network 2 recognizes that the called interface B is associated with an ACR service. Hereby, the ACR service tracked in the smart network, or IN network 3, associated with said switching center 15 provides information by CAP signaling to said switching center of the mobile network. Thus, according to the present invention, it is essential that the ACR service is an intelligent network or [N service] based on the logic of an IN network.

In order to identify the existence of an ACR service according to the present invention and to consider its effect in the connection set-up step, the existence of an ACR service associated with a called client interface •> · B is registered in that application. • · ». •« I '/ service information in HLR register 24, preferably HLR register related memory! * * 25. Information about the existence of the ACR service may also be signaled in the VLR * e · m 25 register of the mobile network 2. 23. Thus, information about the existence of the ACR service associated with the called client interface * * is active at the connection establishment step when the location of the called client interface. in the service area 2 of the mobile network (s).

* ·· »• · * Information about the secret number is transmitted in the ISUP signaling IAM (Initial Address • aa: ··· 30 message), more specifically in the APRI * a · · * indicator of the ISUP signaling“ Calling party number ”parameter (APRI, Address Presentation Restricted Indicator). The APRI indicator can get values: ♦ • t * * * "* I i." Presentation allowed ", 117231 6 ii." Presentation restricted ", iii." Address not available ", and iv." Presentation restricted by network ".

5 When the APRI indicator receives a value of i. Or iii., The call of the calling client interface A can be redirected to the called client interface B, whereby the APRI number i. Of the calling client interface A may be displayed on the display of the called client interface B and iii. The subscription number of the calling client interface A does not appear on the display of the called client interface B.

10

When the access number of the calling client interface A is secret, or when Call-specific number display blocking is used, i.e.. when the APRI indicator receives a value ii. or iv., the calling of the calling client interface A is routed to the exchange 22 of the mobile network 2 to which the called client interface B is connected. In this exchange 22, the IN * control provided by the ACR service of the ACR service associated with the called client interface B 15 recognizes the situation and performs the actions defined by the predefined settings of the called client interface B.

When the called client interface B is running the ACR service, the actions that the ACR service ... 20 can take may be, for example:! * 5 • a) call rejection, • · ab) callback and signaling as specified in the standard, which may be sent back, which may be, for example, the reason code “ISUP # 24” leading to a call in the call center • * "The number you called accept calls with number display blocked ", * 25 c) the call is routed / the call is routed directly to the answering machine, or • · d) something else.

In accordance with a preferred embodiment of the present invention, the mobile network 2 *** exchange 22 (MSC / VLR) identifies the ACR service that the HLR 24 provides information on the ··· · 30 ACR intelligent network service associated with client interface B, by CAP signaling. (Camel, T-CSI, '· * · * Trigger an End Call). Thanks to the invention, the ACR service can thus be implemented, get through without the MAP signaling deficient in implementing the ACR service, and / or avoid modifying the MAP protocol for the ACR service to support the ACR service.

The incoming call control is transferred after triggering the ACR service existence information and 5 as a result of the IN network 3 intelligent network logic, which is now responsible for further processing the call on a case-by-case basis. The result of further processing may be, for example, rejecting the invitation / call. However, further processing may depend on the choices made by the customer, and generally because the ACR service is a network service to be traced to the mobile network switching center, the entire ACR service on / offF state can be set / updated from the terminal to the on / off state e.g.

10 with * 89 # and more. # 89 #. The status of the ACR service can also be updated by contacting the operator.

The invention has been described above only for the purpose of understanding its basic idea by means of a preferred embodiment of the invention. Of course, this is not intended to limit the invention in any way, but within the scope of the appended claims, many alternative and modified solutions are possible, as well as many different / varied single elements of equivalent service functionality essential to an inventive concept.

Further, it can be noted / ·· that the connection set-up signaling can also be traced to utilize a special control database separate from the IN • network, whereby the connection set up control uses this separate control .. .. 25 control database.
