Abstract

A system and method of providing an intelligent automatic roaming analysis (ARA) that enables a roaming mobile subscriber (130) to use abbreviated dialing regardless of the location of the subscriber in a radio telecommunications network (100). The radio telecommunications network includes a home network (106) which comprises a Home Location Register (HLR) (112) and a Service Control Point (SCP) (114). The visited exchanges (122;124;126) of the network are categorized by a type indicator (314) if located outside the home service area (102). Subscription data (300A) and operator service data (300B) are provided as a database in the SCP (114), wherein applicable telephone codes (306;308;310;312) are available for the home network (106) and the visited exchanges (122;124;126). Based on the type of the visited exchange, an abbreviated number is rebuilt into an appropriate called party number (B-number) by utilizing one or more services provided in the SCP.

Description

SYSTEM AND METHOD FOR MARKING ABBREVIATED NUMBERS FOR A TRAVELING SUBSCRIBER PRIORITY ACCORDING TO 35 U.S.C. § 119 (e) & 37 CFR § 1.78 This non-provisional application claims priority based on the following co-pending provisional US patent application filed previously entitled "System and Method of Automatic Roaming Analysis (ARA) for Dialing Abbreviated Numbers in a Wireless Intelligent Network (WIN) ", Series No .: 10 60 / 099,645, submitted on 09/09/98, in the name of Myriam Thibert, Paul Gantous, Charles Gelibet, Giuseppe Conté and Lysanne Gauthier.

BACKGROUND OF THE INVENTION Technical Field of the Invention 15 This invention relates to telecommunication systems and, more particularly, to an automatic tracking analysis system and method (ARA) for dialing abbreviated numbers in a wireless intelligent network (WIN). ) where a mobile subscriber can register abbreviated numbers for calls of origin regardless of the location of the subscriber in the network.

Description of Related Art For current users of telecommunications services (commonly known also as mobile subscribers), short-digit dialing (SDD) or mS UL? tAtl & Speed dialing is a distinct advantage over conventional dialing where all the digits that comprise the full telephone number of a destination party need to be registered. Almost all mobile phones have an abbreviated dialing memory in order to facilitate the dialing of the numbers used more frequently. The conventional method for using abbreviated dialing where the number stored in the memory is read from the memory as such is commonly useful only in a portion of the telecommunications radio network, such as, for example, a portion of the local network associated with the mobile subscriber. Obviously, such a limitation would severely reduce the utility of the SDD feature to a roaming mobile subscriber. Unfortunately, the current commonly available solutions that attempt to solve this limitation in conventional abbreviated dialing are not adequate or satisfactory because they are only extensions of the memory based scheme. For example, assuming that the telephone number in Country X, say, 90 123456 is registered in the abbreviated dialing memory of a mobile telephone. Obviously, it is returned in the same way when it is read from memory to perform abbreviated dialing. If the subscriber is traveling in Country Y and from there wishes to make a call to the same telephone number in Country X, the subscriber can not use the abbreviated dialing facility, since the subscriber now has to register the number that includes the applicable international access codes. Therefore, in this example, the subscriber has to dial the number 099 358 0 123456. Accordingly, for the same telephone number in Country X (local number), the subscriber would have to program a different number 5 of calls originated from each country or region located within each region of network coverage It can be easily appreciated that this scheme requires a large memory for the storage of numerous variations of an individual local number. In addition, the mobile subscriber has to remember the abbreviated memory locations for all variations of the same number, so that only the correct memory location is read, depending on the country or region in which the subscriber is located while making the call. In addition, the problems associated with the methods of Conventional abbreviated dialing are exacerbated in telecommunication networks that cover a larger number of countries, greatly reducing in this way the utility of the feature for international travelers. Accordingly, based on the above description, you must It will be readily appreciated that in order to overcome the shortcomings and disadvantages of the existing solutions, it would be advantageous to have a method and system for providing an intelligent automatic tracking analysis that allows a roaming mobile subscriber to use the abbreviated dialing regardless of the location in the network. from telecommunications. The present invention provides said method and system.

DESCRIPTION OF THE INVENTION In one aspect, the present invention relates to a method for supporting an abbreviated digit dialing service (SDD) for a roaming mobile subscriber in a telecommunications radio system of the type that includes a plurality of exchanges visited. Each visited exchange is provided with an identity indicator (MSCID). For a central office visited outside the local area (called a visited service area) it is also provided with a type designation. A local network is included which comprises at least one visited exchange, an Initial Location Register (HLR), and a Service Control Point (SCP), coupled or not to the HLR. The SCP database includes a set of subscriber data and an operator service data set, and a service execution portion that refers to the abbreviated digit dialing service. The method comprises filling the subscriber data set with at least one International Access Code (IAC), one National Access Code (NAC), one Country Code (CCD) and one Area Code (ACD) for the network local, in addition to MSCID of the plants in it. The method also involves filling the operator's service data set with at least one type of visited exchange serving a visited service area, and an IAC, a NAC, a CCD and an ACD, and an MSCID for the exchange visited the service area visited. When a mobile subscriber dials an abbreviated number from a visited exchange, a determination is made in the SCP whether the mobile subscriber is located or not in a visited exchange. If so, determine the type designation of the visited service area exchange. A call handling instruction can be received at the SCP either from the HLR or from the visited exchange. The call handling instruction preferably includes at least the MSCID of the exchange. The SCP executes a conversion process on the abbreviated number to generate a converted number (TN). Then the SCP determines if the mobile subscriber is roaming. Based on the type designation of the visited exchange, a destination part number (number B) is selectively reconstructed using the TN in the SCP. The originated call is selectively terminated using the number B. In another aspect, the present invention is directed to a telecommunications radio network system comprising a geographical area comprised of a plurality of service areas, each of which is serviced by a mobile communication center (MSC) that has an identification indicator (MSCID). The system includes an SCP to support a set of customer service data associated with a mobile subscriber, an operator service data set for the global definition of the visited MSC and the tracking detecting means to detect whether the mobile subscriber is visiting the service area visited. The customer service data set includes a first plurality of portions of telephone number code associated with an MSC that serves a local service area of the mobile subscriber. The operator service data set includes a second plurality of telephone code portions associated with the MSC serving a visited service area in a type portion for the designation of a type parameter for the visited MSC. In the network system, there are means available for the mobile subscriber to register an abbreviated digit dialing number associated with a calling party's telephone number. Also in the network system is includes an HLR that may be operatively coupled to the SCP. The HLR provides a call handling instruction in response to a service query from the MSC. The SCP executes a service portion in response to the call processing instruction transmitted through the HLR or directly from a when the mobile subscriber is located in the visited service area and registers the abbreviated digit dial number for the destination party. The serving portion returns an indication with respect to the destination part that typically includes a complete B number for the destination part. The subscriber's call is then ends using the number B in the conventional manner. In a further aspect, the present invention is directed to a telecommunications radio network system that allows the tracking of a mobile subscriber in the visited exchange to generate a call by typing an abbreviated number. The system of network is comprised of a local service area, with one or more .., j ^ .l ^ - *? *? »t ^» ^ jfg? v1ifo.- central, which are served by; SCP and possibly an HLR. A visited service area that has one or more exchanges is also included in a network system. All the exchanges have an identity indicator, while those in the service area 5 visited have a type parameter in addition. The network system supports an SDD scheme for the mobile subscriber so that the subscriber can generate calls from the exchanges visited in the local service area or the service area visited using an abbreviated number. The network system includes first means of data set for maintaining the subscriber information information of the mobile subscriber and a first plurality of digit portions. The digit portions are selectively prefixed for a call originated by the mobile subscriber from the local service area by typing a number abbreviated to a destination part. Second means of data sets are also included to maintain a list of the identity indicators, type parameters and a second plurality of digit portions for the exchanges visited in the visited service area. There are detective means in the SCP to detect if the subscriber mobile is located in a visited central office of the service area visited. In response to the sensing means, when a call is placed through the mobile subscriber by typing an abbreviated number in the visited exchange of the visited service area, there are means of Automatic Tracking Analysis (ARA) in the SCP for convert the abbreviated number, where the conversion is based on fc ^ a «^ aB ^ togBts» Mn ^ M ^ g the type of exchange visited and the results in a destination part number. There are also means for transmitting the number of the destination part to the visited exchange such that the call is routed to the destination party.

DETAILED DESCRIPTION OF THE DRAWINGS The innovative teachings of the current patent application will be described with particular reference to the number of illustrative modalities. However, it should be understood that this class of modalities provides only a few examples of the many advantageous uses of the innovative teachings contained herein. In general, the statements made in the specification of the present application do not necessarily limit any of the claimed aspects of the present invention. In addition, some statements may apply for some inventive characteristics but not for others. In the drawings, similar or similar elements are designated with identical reference numbers through the ¿Mfe? ^^^^^^^^^ M ^^^^^^^ different views, and the different illustrated elements are not necessarily drawn to scale. Referring now to the Figure 1, there is illustrated a functional block diagram showing the telecommunications radio network system 100 provided as a Wireless Intelligent Network (WIN). The network system 100 covers a geographic area comprising a plurality of service areas, for example, a local service area 102 and a consolidated visited service area 104, where a mobile subscriber 130, symbolically shown herein as a station mobile, can be located. The local service area 102 is controlled by a local network 106 which comprises one or more mobile switching centers (MSC), each having an identification indicator (MSCID). For example, three MSCIDs labeled with the reference numbers 108A, 108B and 108C respectively are shown herein. The MSCs are operatively associated with an Initial Location Register (HLR) 112 and a Service Control Point (SCP) 114 to form the local network 106 to service the local mobile subscriber service area 102. As is well known in the technique, the HLR 112 and SCP 114 can be co-located as part of a local service node 110, although in some demonstration modalities they can be provided as separate entities. The HLR 112 is provided primarily to maintain the tracking of the mobile subscriber location and the service profile, and to provide the route information to ask the MSCs, either from the area ^^^ Local service fee 102 or from the visited and consolidated service area 104. The SCP 114 is the subsystem which executes several portions of the WIN service based on the information stored here in the service data of the subscriber to provide services from Subscriber The consolidated visited service area 104 may preferably comprise one or more local visited areas, for example, the local visited area 116; one or more national visited areas, the 118 national visited area, and one or more other areas visited international, for example, the international visited area 120. The local visited area 116 is served by a local visited network 122 comprising one or more MSCs, each having an associated MSCID MSCID. For example, two MSCIDs, labeled with the reference numbers 122A and 122B respectively, as show as part of the local visited network 122. In a similar manner, an illustrative national visited network 124, comprising MSCID 124A and MSCID 124B, and an illustrative international visited network 126, comprising MSCID 126A and MSCID 126B, are provided for attend the 118 nationally visited area and the area visited international 120 respectively. A Public Switched Telephone Network (PSTN) 128 may be interconnected between the local network 106 and each of the visited networks, the local visited network 122, the national visited network 124, and the international visited network 126, to provide a route path adequate among MSCs • participants that comprise the WIN 100 system.

"Vffitff ^^ Based on the foregoing, it should be noted that the MSCIDs visited (ie the participating MSCIDs that serve the consolidated tracking area or visited service area 104) are organized into three types in relation to the subscriber's local network mobile: (i) local MSCIDs, (ii) national or regional MSCIDs and (iii) international MSCIDs. In accordance with the teachings of the present invention, the visited MSCIDs are labeled in SCP 114 with a type indicator that is used in the reconstruction of an abbreviated number registered by the roaming mobile subscriber, as will describe in more detail below. Referring now to Figure 2, there is shown a flow chart illustrating an abbreviated digit dialing (SDD) process available to a roaming mobile subscriber in accordance with the teachings of the present invention. The SDD process preferably employs a subscriber service referred to hereinafter as Automatic Tracking Analysis Service (ARA). The FOR service, which presents the teachings of the present invention, is provided as a call origin service (that is, the Activated Service of Origin) to which a cell phone user can subscribe. (subscriber A). Source services are defined as services that have an Origin Service Activator and are invoked when a subscriber is the originator of a call (Subscriber A). The services are activated by the number of the calling party or number A. Preferably, the provision of origin activators is executed by the HLR 122 of the local service node 110. j & »^^ In addition to the PARA service, to which the present invention is particularly directed, the possible originating services may include the following: (i) End User Control (EUC); (ii) Private Numbering Plan (PNP); (iii) Conversion of Massive Number (BNT); (iv) Provision for Outgoing Call (OCA); (v) Outgoing Call Restriction (OCR); and (vi) Closed Group Marking (CGD). Within the context of the present invention, in one sense, all MSCs (or, core) can be considered as "visited centers", including those of the local network 106 that service the local service area 102. And, a local service area of a mobile subscriber, such as the local service area 102 shown in Figure 1, can defined in terms of a service to which the mobile subscriber subscribes, and whether or not it is activated while it is located in the local service area. Accordingly, the local service area 102 of the network 100 may also be viewed as the service area where the ARA service of the present invention is not activated and the consolidated service area 104 visited is the collection of the service areas where the service is active ARA. Specifically, the FOR service provides intelligence in a wireless network such as, for example, the WIN 100 system shown in Figure 1, allowing a subscriber to dial an abbreviated number for a destination party while giving monitoring in the geographical area that is covered by the MSCs a? ft ^ ito ^ i ^^^^ a ... ^^^^ a &&.a participant of the network. The call handling method is designed to produce the same results as if the abbreviated number was dialed from the subscriber's home network. Continuing with the reference in Figure 2, the number abbreviated (AN) recorded by the mobile subscriber (step 202) is first converted in order to obtain a converted number (TN), as shown in step 204. Preferably, the conversion is executed by performing an auxiliary service such as, For example, a Massive Number Conversion (BNT) service or a Private Number (PNP). The PARA service analyzes the location of the calling subscriber in relation to the local network area of the subscriber to determine if the subscriber is roaming, as provided in decision block 206. If the subscriber making the call is not roaming , modification to the existing TN will not occur (step 208). The call is then placed using the TN as the number B (step 210). If tracking is detected in SCP 114, as determined by decision block 206, an additional determination is made (decision block 212) to verify whether is available or not an appropriate FOR service for the mobile subscriber. If so, the TN value will be analyzed and reconstructed for the ARA serving portions (step 214) which will be described in greater detail below with reference to FIGS. 3 and 4. Otherwise, a process may preferably be provided. (step 216). In some implementations, such eaiS ^ **** ^ ^^^? ^^ = ^ átüS ?? .yMBi ^ i ^ aM 5 preset procedures may include providing a pre-recorded announcement or an error indication to the calling subscriber. Alternatively, the predetermined procedure may be as if the call were allowed to travel in accordance with the selection of the operator. In accordance with the teachings of the present invention, the TN value is reconstructed based on the home location of the mobile subscriber. Certain digits, which represent one or more telephone number codes commonly used in the telecommunications industry. telephone service, are concatenated selectively (or, "are prefixed") for the TN value or deleted from it. These codes preferably comprise the following: (i) an International Access Code (IAC), (ii) a Country Code (CCD), (iii) a National or Regional Area Code (NAC), and (iv) a Code of Local Area (ACD). The exact combination of digits that are to be concatenated to the TN value depends on the location of the calling subscriber and the location of the terminating party (ie, destination party). In order to achieve the appropriate combination of additional digits, the information / numbering data related to the Subscriber location A (calling party or originating party) as well as the information / numbering data related to the subscriber's local network (for example, subscription data for the FOR service) are provided on a per-subscriber basis. adequate data. Consequently, preferably a list of values lAC, NAC, CCD and ACD is provided as customer data for the local network (for example, the local network 106 shown in Figure 1) and as operator service data defined globally for each defined MSC that participates in the network and is likely to be visited by the FOR subscriber. In addition, the global data set is preferably indexed with the MSCID type information described hereinabove to determine the appropriate digit information to be added or prefixed to the TN value. Figures 3A and 3B illustrate a currently preferred embodiment of the client and global data sets, 300A and 300B respectively, in tabular form, provided in accordance with the teachings of the present invention in SCP 114. The client data set 300A (also referred to as the end-user subscriber data, which is provided for each subscriber of the PARA service) preferably comprises a portion of name MSC 302, a local MSCID portion 304, a portion IAC 306, a portion NAC 308, a portion CCD 310, and an ACD portion 312. Each record in the MSC name portion 302 comprises an alphanumeric nickname for a corresponding MSCID of the MSCs serving the local network area. In addition, the appropriate values for each of the code portions are registered for the named local MSCs. For convenience, the code portions of the client data set 300A can be referred to hereinafter as local IAC (H-IAC), local NAC (H-NAC), local CCD (H-CCD) and ACD (H-ACD) ) local respectively.

The global data set 300B (also referred to as the operator's service data set) is defined by the operator of the telecommunications radio network as a list of all the MSCIDs visited by each subscriber, and the corresponding code and type portions As can be easily appreciated, the portions of the global data set 300B are very similar to those described above with reference to the client data set 300A, except that the global data set 300B also comprises a portion of type 314 to label the visited MSCIDs of the network. As explained in the above description, the currently preferred mode of the 300B operator service data set includes three types of MSCIDs visited: local, national and international. Consequently, each of the visited MSCIDs provided in the MSCID portion are labeled with a type indicator: LOCAL, NAT or NT as appropriate. Again, for convenience, the code portions of the data set 300B can be referred to hereinafter as the visited IAC (MSC-IAC), visited NAC (MSC-NAC), visited CCD (MSC-CCD) and ACD (MSC) -ACD) visited respectively. In the presently preferred embodiment of the present invention, the telephone code values IAC, NAC, CCD and ACD, described above, preferably comprise up to four digits. However, it can be appreciated that the ACD code may not exist in some cases where certain countries do not require an Area Code.

The service FOR of the present invention provided as a call origination service is invoked to identify the service key (number A) and Subscriber Origin Activator in the service MSC. If the subscriber is roaming in an area served by an MSC that supports ANSI-41 signaling, the PARA service is invoked to identify the Activator of Origin. Preferably, the originating MSC supports a message of Source Access (IS-41 +) or an ANSI-41 Origin Request message between the MSC and the HLR or SCP. In addition, to have a subscription to the ARA service defined in the SCP, the subscriber is preferably required to have the appropriate origin category in the HLR. Initially, the TO service detects if there has been a conversion of the abbreviated number to generate a TN. In addition, the logical service flow of the ARA service preferably detects whether the calling subscriber is roaming outside the subscriber's local service area by verifying whether or not the received MSCID corresponds to the subscriber MSCID provided in the client data set 300A. If it is not the same, then the subscriber making the call is considered itinerant and the TO service preferably proceeds with the comparison of the TN to reconstruct the number B. It should be noted that to the reference of this, that the subscriber categories with origin activators are preferably transferred to the MSC in which the subscriber is roaming, as this will ensure that the HLR / SCP 112/114 (shown in Figure 1) «* ^" "F + V be consulted during the call setup. The HLR 112 of the subscriber is consulted during the establishment of the preferred call so that the source category causes the HLR 112 to consult the SCP 114 for the treatment addresses of the subscriber. appropriate calls. In some cases, the SCP 114 can be directly consulted during the call setup without going through the HLR 112. Referring now to Figure 4, there is illustrated therein a flow chart showing a mode currently Preferred of a call number setting process provided in accordance with the teachings of the present invention as part of the aforementioned ARA service. The process starts by determining the type of the visited MSCID (step 402) from which the mobile subscriber originates a call using the dialing of abbreviated digit. Corresponding to the three types described hereinabove, three separate trajectories, a local MSCID path 404A, a national MSCID path 404B and an international MSCID path 404C, are provided. When determining the type of MSCID, one of these trajectories is taken to the additional analysis. Depending on certain flow control conditions, some of the paths may have common flow segments, as will be described below. After taking the local MSCID path 404A, a determination is made (decision block 405) to verify whether there is the MSC-SCD. Otherwise, the converted number, ie TN is left intact without further processing (step 408) and the call with the TN is terminated as the number B. if the MSC-ACD exists, then an additional determination is made (decision block 406) to verify if the local ACD equals to the MSC-ACD. From If so, the TN is left intact without further processing (step 408). If the type determination in the decision block 402 produces a national MSCID type or if the local ACD is not equal to the MSC-ACD, then the control flow enters a decision block 410 where it is determined whether the TN includes a lAC . If the TN includes a μL, the TN is left intact again without further processing (step 408). Again, the call is terminated using the unmodified TN as the number B. If the decision block 410 determines that the TN does not include the IAC, a next decision block 412 determines whether the TN includes a NAC. If so, it is again verified whether or not the MSC-ACD exists (decision block 413). Otherwise, the TN is left intact again without further processing (step 408). Otherwise, the ACD in the TN is verified if it is equal to the MSC-ACD (decision block 414). If so, the TN is updated keeping only the local number part and discarding the rest of the digits (step 418). The updated TN is then used as the B-number for the call termination. If the decision block 414 determines that the ACD portion of the TN is not equal to MSC-ACD, then the TN value is left intact (step 408) and use it as the number B. If the block of decision 412 determines that the TN does not include the NAC, the TN is updated by prefixing an appropriate local NAC and local ACD (step 416), as provided in the 300A subscriber data set. The default value is then used as the number B for the call termination. It should be appreciated that the local ACD is aggregated only if it exists. Otherwise, the TN is reconstructed without it. If the type determination in decision block 402 produces an international MSCID type, the MSCID path International 404C is taken for further analysis. A decision block 420 first determines whether the TN includes an IAC. If so, a next decision block 430 determines whether the CCD portion of the TN is equal to MSC-CCD. Otherwise, the TN is updated by replacing the lAC of the TN with the MSC-IAC provided in the set data from the operator 300B (step 434). The reconstructed TN is then used for the call termination process. If the CCD portion in the TN is equal to MSC-CCD as determined by the decision block 430, the flow control then enters a decision block 431 where it is determined whether there is the MSC-ACD. Otherwise, the lAC and CCD portions are removed from TN (step 433). The modified TN is used for call termination. If the MSC-ACD exists, a decision block 432 determines whether the ACD portion in the TN is equal to MSC-ACD. If so, the TN is updated keeping only the part of the local number (step 436) and discarding the portions ^^^ ^^^^^ áßmm ^^^^^^^^^^^^^ remain of it. On the other hand, if the TN-ACD is not equal to MSC-ACD, the TN is reconstructed by replacing the lAC and CCD portions with the MSC-NAC (step 428). If the decision block 420 determines that the TN does not include a lAC, a decision block 422 determines whether the TN includes a NAC. If so, the TN is updated by replacing the TN-NAC with MSC-IAC and local CCD, as provided in step 424. Otherwise, the TN is reconstructed by prefixing MSC-AIC, the local CCD and the local ACD ( step 426). Again, it must be that the local ACD is used only if it exists. It should be readily apparent to those with evidence in the art by reference to the present that the currently preferred mode of the call number setting process described hereinabove can also be provided with a variety of error handling processes such as for example , exception handling, service portion error handling, and SCP error handling. The exception handling in the ARA service of the present invention may include conditions such as: blocked subscriber conditions, blocked service condition, and undefined MSCID location condition. Upon the occurrence of those conditions, the ARA service may preferably return an announcement code to the HLR and may stop service processing in the SCP. Service portion error handling in the ARA service occurs when the service portions detect a condition that prevents the service portions from completing their processing. Upon the occurrence of one of these conditions, the ARA service preferably establishes an error code for diagnosis, etc. and stops the processing of the service in the SCP. Errors that occur during the execution of the service and are not detected by a portion of the service are referred to as SCP error handling conditions.

Preferably, those conditions result in appropriate error codes for diagnostics, monitoring, etc. Referring now to Figure 5, there is shown a functional block diagram of a network 500 of the illustrative telecommunications radio network 100 shown in Figure 1. The portion 500 of the network 500 is provided in accordance with the teachings of present invention for supporting abbreviated digit dialing for roaming mobile subscriber 130, illustrated herein as an equivalent functional block of a mobile telephone. The mobile subscriber 130 uses an input device 502, preferably available as part of the mobile telephone, to register an abbreviated digit or abbreviated number when it wishes to originate a call. Also, an activator / deactivator 504 is available to the mobile subscriber 130 to selectively activate or deactivate the ARA service described hereinbefore. Preferably, the activator / deactivator 504 is available only to those mobile subscribers who have a subscription to the End User Control (EUC) service in addition to the ARA service. One illustrative visited exchange in the consolidated visited service area 104, for example, the MSC 126A, serves the visiting mobile subscriber 130. The exchange 126A preferably comprises a data set 512 for storing the subscriber category information transferred thereto. This Subscriber category information ensures that the HLR / SCP is consulted during call establishment. Accordingly, an appropriate interrogation mechanism 514 is provided for it complies with the applicable signaling protocols. The local network 106, comprising HLR 112 and SCP 114, inter alia (shown in Figure 1), is provided with abbreviated digit converter 506 in SCP 114 (e.g., a PNP or BNT mechanism) to convert the abbreviated number registered by mobile subscriber 130 into converted number. A tracking detector 508 is provided in the SCP 114 to detect whether the mobile subscriber 130 is in a visited area. A mechanism 510 is also provided as part of the local network (in SCP 114) to elaborate and update the converted number to generate a suitable B number in accordance therewith. Figures 6A, 6B and 6C illustrate examples of the flow of signal illustrating the signaling required to support abbreviated digit marking in accordance with the teachings of the present invention. Referring in particular to Figure 6A, the AIN is shown as the originator of origin. When the mobile subscriber 130 dials an abbreviated number (signal path 604), the [A #] and [ABBR. NO.] Are transmitted to the MSC 126A together with the * 1r1i¡B-BB _iÉ- ^? same. By means of an Invoke Origin Request (ORIGNOT) message (signal path 606), the visited MSC 126A passes the information [MSCID], [A #] and [ABBR. NO.] To the local HLR 112. The local HLR 112 provides a message to Summon Service Request (SERVREQ) to the SCP with the appropriate parametric information as shown in the signal path 608. It can preferably be provided that an origin conversion service is executed first for the mobile subscriber 130, thereby ensuring that a conversion process of digit abbreviated precedes the service portion PARA. After the SCP executes the appropriate portion of the call number establishment process provided in accordance with the teachings of the present invention, a number B is returned to the HLR by means of the SERVREQ 610 Return Result message path, which is propagated to the visited MSC 126A by means of the Origin Request Return Result message path 612. The call originated by the mobile subscriber 130 is then terminated with the number B of a destination part 602 (path 614 call transmission). Figure 6B illustrates a second example of the signal flow for the SSD process. It should be appreciated that this example is similar to one provided in Figure 6A, and consequently, only the salient features are described here. The OTG is provided as the origin activator in this modality. Upon receiving the Incoming Call 604, the message to Summon the Request of Origin (ORREQ) 702 is a proportion of the MSC 126A to the HLR 112, including the parametric information as described. The parametric information is then passed to SCP 114 by propagating the message to Invoke ORREQ 704 to it. The B # is subsequently returned from the SCP 114 by means of the ORREQ 706 and 708 return result message segments. The call is then terminated with the B # of the destination part 602 as shown by the call transmission path 614. 10 In some cases, the appropriate parametric information can be passed directly from a central office to the SCP. This scenario is illustrated in Figure 6C. It should be readily apparent to one skilled in the art that the signal flow in the present is substantially similar to that described with reference to the Figure 6C. The message to Invoke ORREQ 710 is received directly by SCP 114 from the MSC 126A, together with the parameters as shown. Subsequently, the number B is sent to the central MSC 126A, to effect the call transmission path 614. Based on the foregoing, it should be evident Now for those of skill in the art that the present invention provides an advantageous solution that allows a mobile subscriber to dial abbreviated numbers as it is roaming in plural types of visited exchanges as if the abbreviated number was dialed from the subscriber's local network . 25 Especially provides an attractive service for users end that wish to support international abbreviated digit dialing. By means of the ARA service of the present invention, the end user is able to continue using abbreviated digit dialing regardless of their location. It should be appreciated in addition that the PARA service can be considered as an innovative improvement for Wireless Virtual Private Network (WVPN) solutions currently available. Although the system and method of the present invention have been described with particular reference to certain radio standards In the case of telecommunications (for example, the ANSI-41 standard), it should be recognized by reference herein that the innovative teachings contained herein are not necessarily limited thereto and may be advantageously implemented with any applicable telecommunications radio standard. In addition, it should be considered that the operation and construction of the present invention will be apparent from the foregoing description. While the method and system shown and described have been characterized as preferred, it will be readily apparent that various changes and modifications of the same without departing from the scope of the invention as defined by the claims set forth below. For example, as an optional feature, a subscriber could supply a list of B numbers (non-SDD numbers) that would be labeled using the ARA functionality so that the Subscriber can dial numbers in a tracking area as if the dialing was done from the local network. In this way, it may not be necessary to run an abbreviated digit conversion service before the ARA service. In addition, ARA subscriptions can be defined for groups of subscribers, called Selective User Groups (SUGs). It should be appreciated that although the teachings of the present invention have been exemplified by means of an individual subscriber, they are equally applicable to SUGs, mutatis mutandis. While it is possible that the ARA service can interact with other services using WIN using the same source category, it is contemplated that such interactions will be resolved within the scope of the present invention. In addition, it should be appreciated that the ARA service of the present invention may be extended to include the option where certain telephone codes are not provided or necessary, as is the case with some plants visited. For example, in some countries, there is no ACD code and only one IAC / CCD / NAC combination is prefixed for the local number. Furthermore, based on the above discussion with reference to Figure 4, it should be clear that the call number reconstruction process may include prefixing, annexing, replacing, replacing, transposing, adding, updating, concatenating, inserting, overriding, rejecting or otherwise manipulating or leaving one or more digits of the TN intact. Therefore, the phrase "reconstruction" is considered to include all digit manifestations within the scope of this ¿^^ ¡^^^^^ ¡¡¡¡¡^ ^^^^ M invention. Accordingly, those skilled in the art should understand that all these and other changes, combinations, rearrangements and extensions of the innovative teachings contained herein are expressly considered as part of the scope of the present invention which is limited only by the claims next. ^^^^ «^^^^ g ^ - ^^^ '^ a f ^ te ^ 3 ^^ * ^^ - * • - - > **** »**. - * ft * '
