MXPA99005649A - Selective carrier denial for mobile subscribers - Google Patents

Abstract

Selective carrier denial in a cellular system restricts some or all carrier-handled calls from a given cellular subscriber while simultaneously allowing other cellular calls. A restriction flag or indicator in a Visitor Location Register (VLR) of the cellular system is set by a Home Location Register (HLR) which contains a list of those carriers denied to subscribers. When the restriction flag is set, the HLR is interrogated to determine if the call is restricted. Alternatively, the restriction flag may reside within the subscriber's mobile phone. Further, the VLR or mobile phone may, respectively, contain a list of denied carriers and internally determine if carrier denial applies without resort to the HLR.

Description

SELECTIVE DENIAL OF THE CARRIER - FOR MOBILE SUBSCRIBERS FIELD OF THE INVENTION The present invention relates, in general, to a telecommunications system and to the method that incorporates the selective negation of the carrier, specifically, to a telecommunications system and the method for the selective negation of the carrier in an environment wireless, and more specifically, to a system and method for selective negation of the carrier in a cellular, mobile environment.

BACKGROUND AND OBJECTIVES OF THE PRESENT INVENTION The evolution of wireless communication during the last century has been remarkable, since Guglielmo Marconi's demonstration in 1897 of the radio's ability to provide continuous contact with ships that sailed the English channel. Since the discovery of Marconi, new methods of wired and wireless communication, services and standards have been adopted by people all over the world. This evolution has been accelerating, particularly during the last 10 years, in which the mobile radio communications industry has grown by orders of magnitude, thanks to numerous technological advances that have made the portable radio equipment smaller, more economical and more reliable. The exponential growth of mobile telephony will continue in the coming decades as well, as this wireless network interacts with and eventually exceeds existing wired networks. The United States wire network currently has a constant access feature called Selective Carrier Denial (SCD), a feature that provides the ability for a telephone service provider to request a carrier, such as AT & T, block the access of the subscriber to interurban calls on this carrier, but without limiting these subscribers to make non-interurban, local calls or calls using other carriers. In particular, the SCD allows the wireline provider to selectively inhibit certain calls handled by the carrier from those subscribers who have been designated as subscribers without charge, but allow them to make local and emergency calls without restriction. The Federal Communications Commission (FCC) recently indicated that for security reasons wireless providers in the United States would soon be required to incorporate equal access capability into their wireless systems. Currently, the SCD feature is not available in cellular systems in the United States, such as PCS 1900. It is, therefore, an objective of the present invention to implement the Selective Negation feature of the cell carrier. wired systems in wireless telephony systems, particularly those United States in accordance with the mandate of the FCC. Another objective of the present invention is to incorporate Selective Negation of the Carrier in cellular systems, limiting to subscribers access to specific carriers, groups of carriers or all carriers.

COMPENDIUM OF THE INVENTION A telecommunications system and method for the selective negation of the carrier provides an operator of a Public Land Mobile Network (PLMN) the ability to * limit or inhibit certain calls handled in carrier of a given cellular subscriber, while same time allows other cellular calls. In one embodiment of the present invention, a restriction flag is included in a Visitor Location Register (VLR) for each cellular user. When the user attempts to make a carrier-to-carrier call and the restriction flag is set, the Residence Location Register (HLR) for the PLMN determines whether the restriction applies and whether the call on the selected carrier should be denied. In another embodiment of the present invention, the selective negation of the carrier is applied to the systems and methods of intelligent networks. In yet another embodiment of the present invention, the selective denial of the carrier is applied within a subscriber mobile telephone without directly involving the HLR. A more complete appreciation of the present invention and the scope thereof may be obtained from the accompanying drawings which are briefly summarized below, the following detailed description of the presently preferred embodiments of the invention and the appended claims.

DETAILED DESCRIPTION OF THE PRESENT INVENTION The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention will be shown. This invention, however, can be incorporated in very different ways and should not be considered as limited to the modalities set forth herein; instead, these embodiments are provided so that this description is thorough and complete, and will fully carry the scope of the invention to those skilled in the art. With reference to FIGURE 1 of the drawings, this illustrates a Public Land Mobile Networ (PLMN, Public Land Mobile Network), such as the cellular network 10, which in turn consists of a plurality of areas 12, each one with a Mobile Switching Center (MSC, Mobile Switching Center) 14 and a Visitor Location Register (VLR, Visitor Location Register) 16 integrated into it. The areas of the MSC / VLR 12, in turn, include a plurality of location areas (LA) 18, which is defined as that part of a determined area of MSC / VLR 12 in which a mobile station (MS) 20 can move freely without having to send updated location information to the area of the MSC / VLR 12 which controls this LA 18. Each location area 12 is divided into different cells 22. The mobile station 20 is the physical equipment, for example, a car phone or other portable telephone, used by mobile subscribers to communicate with the cellular network 10. A base station (BS) 24 is the physical equipment, illustrated for simplicity as a radio tower, that provides radio coverage to the geographic area of the cell 22 in which it transmits the radio traffic to and from the MS 20. With another reference to the FIGURE 1, the service area of the PLMN or cellular network 10 includes a residence location register (HLR) 26, which is a database that maintains all subscriber information, for example, user profiles, Current location and routing, International Mobile Subscriber Identity numbers (IMSI, International Mobile Subscriber Identity), and other administrative information. The HLR 26 may be co-located with a given MSC 14, an integral part of the MSC 14, or the multiple service MSCs 14, the latter of which are illustrated in FIGURE 1. The IMSI is a unique identification number of 15. digits assigned to each mobile station 20, and includes a Mobile Country Code (MCC, 3-digit Mobile Code), a Mobile Network Code (MNC, Mobile Network Code) of two (or three) digits and a Mobile Subscriber Identification Number (MSIN, Mobile Subscriber Identification Number), the last two being a National Mobile Subscriber Identity number (NMSI, National Mobile Subscriber Identity). The VLR 16 is a database containing information about all the mobile stations 20 currently located within the MSC / VLR area 12. If a mobile station 20 goes to a new MSC / VLR area 12, the VLR 16 connected to this MSC 14 will request data about this mobile station 20 from the HLR database 26 (reporting at the same time to HLR 26) about the current location of the mobile station 20. Accordingly, if the user of the mobile station 20 then wants to make a call, the local VLR 16 will have the requisite identification information without having to re-interrogate the HLR 26. In the above-mentioned manner, the VLR and HLR databases 16 and 26, respectively, contain various subscriber information associated with a given mobile station 20. In a first embodiment of the present invention, additional information for each subscriber, specifically, carrier restriction information is stored in these databases. In an alternative embodiment of the present invention, which is described and explained below, the carrier restriction information is sent to the subscriber's radiotelephone, for example, mobile station 20, where it is stored. Now with reference to FIGURE 2, a portion of the total network 10 of FIGURE 1 and a series of numbers representing a corresponding number of steps are shown, as will be described below. The mobile station 20, when energized, initiates a registration message for the appropriate MSC / VLR (shown as an integrated device 17 in FIGURE 2) in the area of the MSC / VLR 12 and records the requisite information therein (step 1 as illustrated). The MSC / VLR 17 then sends signals to the HLR 26 requesting the subscriber data associated with the specific recording device 20 (step 2). The HLR database 26, according to the first embodiment, includes a plurality of data records 26A of carrier restriction information in each subscriber, and sends to the VLR 16 in device 17 (step 3) an instruction for establish a restriction flag register 16A in the VLR 16 database if the specific subscriber has any of the restrictions applicable to the carrier. For example, if the subscriber has not paid his telephone bill for a given carrier (and is considered a subscriber without charge by this carrier) the restriction flag 16A associated with this subscriber is established and the MSC / VLR 17 receives an affirmative indication from the HLR 26 that applies a restriction. The subscriber data, together with the set restriction flag 16A for this subscriber, are then stored within the VLR 16 for later use. After the MS 20 has registered in the service area of the local MSC / VRL 12, that is, information in the MSC 20 is stored in the VLR database 16, the mobile station 20 can then attempt to initiate a call. Now with reference to FIGURE 3, a network portion is shown as in FIGURE 2, but with a communications link 28 to other systems, for example, other areas of the MSC / VLR 12 within the PLMN or other PLMN, a Public Swítched Telephone Network (PSTN), an Integrated Services Digital Network (ISDN), or other wired or wireless systems. After the MSC 20 initiates the call (step 1, as illustrated) and establishes a link --- with the MSC / VLR (also shown as an integrated device 17 in FIGURE 3), the MSC / VLR 17 determines whether whether a long distance, long distance or carrier access call is requested (step 2).

If the call is local or if the restriction flag 16A for this subscriber is not established, then the call goes to the appropriate destination either within PLMN 10 or through link 28 (step 6, as illustrated in FIGURE 3) . However, if the call is a carrier or intercity call, that is, the restrictions could be applied to this specific call or call type, and the restriction flag 16A is established, then more information is needed to assess whether this is Private call by this specific subscriber is allowed. The MSC / VLR 17 sends signals to the HLR 26 (step 3), sending the relevant carrier identification information, for example, for AT &; T the number 288 represents its carrier code, to the HLR 26. A carrier restriction function, also stored within the HLR 26, compares the identification information of the carrier sent by the MSC / VLR 17 with a list of restricted carriers for this subscriber (step 4) stored in the data record 26A for this subscriber. If the chosen cell carrier can be used, that is, the identification of the carrier does not match any of the carriers or restricted carrier types, stored, then the HLR 26 sends signals to the MSC / VLR 17 (step 5), which then complete the call, for example, through link 28 (step 6). However, if a match is found and the chosen cellular carrier is a restricted one, then the HLR 26 sends signals (step 5) to the MSC / VLR 17 accordingly, which then rejects the call and sends the reason for this back to the mobile station 20 (step 7) showing the subscriber an invalid carrier selection message. It should be understood that HRL 26 will also disable or reject a definition of a call forwarding number that uses a restricted carrier. With another reference to FIGURE 1, a Service Order Gateway (SOG, Service Order Gateway) 32 is shown connecting the HLR 26 to a Customer Administration System (CAS, Client Management System) 34 through which an administrator network can modify the database of HLR 26, based on the subscriber, to manifest the changes in the status of the subscribers. For example, if a given subscriber becomes a subscriber at no charge to one or more carriers, then the network administrator enters a list of these carriers not allowed through CAS 34 and SOG 32 and stores it within the subscriber data records 26A of the HLR database 26. It should be understood that the restriction flag 16A in the first embodiment of the present invention is preferably a generic flag, i.e. flag 16A in the MSC / VLR 17 only indicates that a generic carrier restriction has been placed on this subscriber, not a specific restriction. The specific restriction information, as described, is stored within the respective data record 26A of HLR 26 for this subscriber. However, it should be turned on that a multiplicity of small restriction flags 16A may be available to each subscriber, which indicates a corresponding multiplicity of specific restrictions. For example, flag 16A? in the VLR 16 can it indicate an AT & T constraint, the 16A2 flag, a SPRINT constraint, etc., or the 16A flag? it may indicate the tolerance or restriction of the types of carrier access calls, which are described in more detail below. It should also be understood that in a second embodiment of the present invention the HLR 26 may send a list of carrier restrictions about a specific subscriber for storage within the appropriate VLR 16. For example, a multi-bit or multi-word flag or data record representing particular carrier restrictions or carrier restriction types can be lowered to VLR 16, which can then perform the appropriate comparison, that is, the function of carrier restriction mentioned above, at this point without involving the HLR 26. Otherwise, where the number of carriers is excessive, it is possible to download a partial list, preferably the candidates to which it is most likely to have access. In any case, full, partial or particular updates for the VLR 16 are necessary on a regular basis to maintain accurate information of the subscriber's restriction. It should further be understood that the above embodiments of the present invention can be adapted for related uses, for example, to provide selective negation capability of the carrier to an intelligent network (IN) such as a toll-free telephone service, that is, a service through which a company has a universal number to which all incoming calls for this company will be charged. When this number is dialed, regardless of the location of the caller in the country, the call is automatically routed to the nearest or most appropriate office of the company, for example, a central office open at any time or a regional office open in days and business hours. Selective denial of the carrier may be employed in the ways described in the present application to limit access to a caller to the universal number, thereby avoiding a charge for this number by an ineligible marker. FIGURE 4 shows a third embodiment of the present invention aimed at incorporating the SCD capacity in an IN cell, as already described. In particular, after the MSC / VLR 17 identifies the call as an IN call, the call is then routed to the nearest Service Switching Point (SSP) 36, which has the Service Switching Functions (SSF, Service Switching Functions) conventional in it, as it can be to establish drive tables. The SSP 36 communicates with a Service Control Point (SCP) 38 that contains the control functions of the service therein, which include the routing and determination functions necessary for the SCD, such as those incorporated in the data registers 26A of HLR 26 in the first embodiment. For example, after the MSC / VLR 17 routes a subscriber call to the SSP 36, the identification of the carrier is then sent to the SCP 38, which analyzes the carrier identification and determines if there is any restriction. If there is not any, the call continues. If restrictions apply, a message is sent back to the MSC / VLR 17 that the call has been denied. FIGURE 5 shows a fourth embodiment of the present invention aimed at incorporating carrier restriction capability in a database 20A within the mobile station 20. The database 20A, which may reside, for example, in a Subscriber Identity Module (SIM) Card (Subscriber Identity Module) conventional, can include in it a carrier restriction flag, which, if established, indicates that more specific carrier restriction information is required, as describes Otherwise, a multiplicity of flags representing a corresponding multiplicity of carrier restrictions or a carrier restriction list, as in the second embodiment, may be downloaded, from the HLR database 26 through the respective MSC 14. , to the mobile station 20 for storage within the database 20A. In this way, the carrier restriction function can be performed within the mobile station 20 itself without using any of the air resources of the PLMN 10. For example, if the database 20A indicates that a restriction of carrier and the subscriber marks an initial "w10", that is, an attempt to place an interurban call, then the attempt is terminated at the mobile station 20 without involving the network.It should be understood that the method and system of the present invention also it is useful where different protocols come into contact, for example, PCS 1900 and GSM In this scenario, the MSC / VLR 17 in one system, for example, the PSC 1900 in the United States, makes contact with the HLR 26 in another, for example, the GSM of Europe and, through the use of the IMSI identification numbers, selective carrier denial information is exchanged.The modalities described above can be said to provide selective denial capability of the carrier. the carrier to a telecommunications system, selectively denying access to the carrier case by case according to the restriction flag records 26A, 16A or 20A stored in the HLR 26, the VLR 16 or the M 20, respectively. Another variant of this theme is to restrict access to the call at a broader level, for example, all interurban calls or specific types of carrier access calls, referred to herein as restricted carrier denial, as described below. . Referring again to FIGURE 1 of the drawings, a mobile subscriber in the PLMN 10 system, such as PCS 1900, can subscribe to a Presubscribed inter-Local Access Transport Carrier Area (PIC) (Presumed Carrier of the Carrier Area). Inter-Local Access Transportation) in this system. This carrier information is then placed by the network administrator within the appropriate register 26A of the HLR 26, also known as the profile data of the subscriber. The mobile subscriber, represented by the mobile station 20 in the figures, has the option of 1 / invalidate your own PIC, that is, the assigned carrier, according to the call by dialing a Carrier Access Code (CAC, Carrier Access Code) before number B. In addition, cell phone rental companies may require the user to use only the designated carrier (PIC) on their phones, and prohibit the user from making CAC calls. It should be understood that the MSC 14 / VLR 16 serving this mobile subscriber has the ability to use a predetermined carrier in the event that a specific PIC or CAC is not defined by this MSC 14 / VLR 16 and replacement with the default carrier. In this way, the subscriber of the mobile station 20 can make InterLATA, intraLATA and other interurban calls without restrictions. In the same way, a Gateway MSC (GMSC) 40, which service calls to mobile subscribers, as shown in FIGURE 6, can also use a predetermined carrier where specific PIC or CAC is not provided. In this way, a call originating from the mobile subscriber (or call sending) and terminating in the one requiring a carrier connection will be routed to the relevant carrier according to the CAC, PIC or indicated default carrier and in this order. When the mobile subscriber passes between the cells 22, the location or service areas 18 or 12, respectively, or otherwise within the PLM area 10, location updates are performed periodically, updating the HLR 26, depending on the location of the subscriber . Updates are also made when the MS 20 is powered up, as described. For example, the response of HLR 26, step 3 as illustrated and described in relation to FIGURE 2, sends a conventional lnsert_Subscriber_Data instruction which, according to this embodiment of the present invention, includes a representation of the carrier capacity currently available. for this mobile subscriber, for example, only P1C calls. It should be understood that the PiC information may be entered into the HliR 26 through the CAC 34 and SOG 32, as illustrated and described in relation to FIGURE 1, updating the HLR 26 database accordingly. It should also be understood that the GMSC 40, which coordinates a call to the mobile subscriber, i.e. the mobile station 20, will interrogate the HLR 26, and the relevant data records 26A therein as the subscriber's current location within the PLMN 10, the roving number of the MS 20 and the applicable P1C or other carrier code applicable to this subscriber receiving the call, all this information is sent to the GMSC 40. In more detail and with reference to FIGURE 6, the GMSC 40 receives an incoming call (step i, as illustrated) to the aforementioned mobile subscriber and requests (step 2) routing information regarding this subscriber from the HLR 26, which sends (step 3) the location information and carrier described above to the GMSC 40, which makes the necessary connections and sends this information to the relevant MSC 14 and VLR 16 for this location (step 4) if no relevant restrictions apply for this subscriber. In the manner described above, broad restrictions may be placed on a mobile subscriber or user such as specific types of calls, for example, all restricted carrier calls, while the selective carrier denial modalities described above are directed primarily at restrict communications through specific carriers. Although the selectively restrictive modalities described above provide a more flexible carrier denial solution, an advantage of this embodiment of the present invention, the fifth one, is that it is easier to carry out. For example, by using categories of broad restrictions there is no need to handle hundreds, thousands or even tens of thousands of different carriers, and the consequential memory consumption and complex management requirements associated therewith. In addition, new communication protocols are not necessary and it is possible to use existing protocols, such as the Mobile -z signaling.

Application Part (MAP, Mobile Application Part), for example, the aforementioned MAP insert_Subscriber_Data instruction, by means of which HLR 26 sends subscriber data including the carrier restriction code. Accordingly, it should be understood that the data records 26A, the information of the restriction flag 16A and restrictive information in the database 2ÜA may, instead of constituting each a new small record, each constituting a portion of ios subscriber profile data stored in HLR 26 or downloaded from ei m. V- or --- - --- to l with the description established in relation to the previous modalities. According to this fifth embodiment of the present invention, a code, flag or restriction indicator of the carrier is added to the data protocol of the subscriber profile, indicating this indicator the specific type of carrier restriction applicable to this subscriber, as describes, the indicator is stored, along with the other data of the subscriber profile, in the HLR 26 and passed to the VLR 16 in the aforementioned insert_Subscriber_Data message. With reference to the termination scenario of the subscriber's call in FIGURE 6, the indicator and other information are sent from the GMSC 40, which he obtained from the HLR 26 in LS. one sign! Send_Routing_lnformation_Acknowledgment, to the relevant VLR 16 in the current subscriber location. The operation of this carrier denial mode of the present invention in the context of the call origin is as follows. When the MS 20 originates a call that requires a carrier, the MSC 14 / VRL 16 will verify the indicator, for example, flag 16A, for a restriction, if there are no indicated restrictions the default handling is applied and the call continues in a way conventional. If the I6A flag indicates that carrier calls are not allowed, then the call "i 'r-»' í- * - i'r * - ---- n'-3 or < --- »s 1 -i \ r e_ í --- i \ tsa ar.tt to py-om in '-i -. -nn - go / - "make" the subscriber or user. If the indicator flag 16A indicates that carrier calls are allowed only in Pi, then no other carriers can be used. Therefore, if a called Foot is made, the call proceeds in the conventional manner as described, but, if a CAC call or other interurban call is attempted, then the call is terminated and the appropriate announcement is made. In the same way, in the context of the termination of the call, when the GMSC 40 receives an incoming call, which must be sent to the relevant MSC 14 via a carrier to an MS 20, the carrier restrictions may be applied. The GMSC 40 first interrogates the HLR 26, that is, sends a Send Routing Information request as follows: shows in FIGURE 6, which responds with the profile data that includes the indicator for this subscriber. i no restrictions apply, the call continues in a convenient manner. If calls are not allowed through the carrier, the call is terminated. If the call is made over the allowed carrier, then the call is continued, or it is also terminated. For example, if the "residence" of the mobile subscriber is in Los Angeles and the subscriber is currently in New York, then a call to the subscriber proceeds from the GMSC 40 in Los Angeles to the relevant MSC 14 / VLR 16 in New York. through one? tO Hr. r-3 or s --íc? r »? ? - 1 a rr H ist "or t- - *? Oi? R1 - aopf" ii "i •? O r \ o In this case it will be a default Foot or Carrier in this order. number of carrier restrictions, different, is preferred in small number, the number of these restrictions can be of any size, however, it is preferred that the number be small enough to be compatible with storage within the existing protocol mechanisms , as it can be the AP signaling It should also be understood that the indicator described above can be resident within the 2QA database of the MS 20. In this way, the calls that originate from MS 20 can be explored before entering the network 10. In other words, if there are no restrictions indicated within the 20A database, the default handling is applied and the call proceeds through IO network. If all carrier calls are restricted, the call is terminated with the appropriate advertisement to the user, such as on a screen. Finally, if only Pie calls are allowed, only Foot calls enter into network 10. CAC calls or other interurban calls are terminated at the source in the manner described above. In addition, it should be understood that the indicator described above in the 2QA database of MS 20 may refer to the HLR.

The specific carrier in question is restricted, that is, by reference to the 26A database, or it may refer to the i 6A database within the respective VLR i6 to make this determination without going any further and involving the HLR 26 and other resources of the system. The foregoing description is of the preferred embodiments for carrying out the invention, and the scope of the invention should not necessarily be limited by this description. The scope of the present invention is instead defined by the following claims.
