Description

APPARATUS AND METHOD FOR IDENTIFICATION PE PARTIES APPLICANT FOR MOBILE STATION INACTIVE BACKGROUND OF THE INVENTION 5 Ca mpo Technician This invention relates generally to apparatuses and methods for applicant identification services. More particularly, the invention relates to a method and system that provides identification of requesting parties attempting to reach an inactive mobile station, after the mobile station has been reactivated. 15 Prior Art History Personal communication products, such as mobile phones, have become very important to the public for business and personal reasons. These instruments provide 20 a mechanism for communication with almost immediate results. In particular, cell phone equipment provides a wide variety of features for the convenience of customers. These include three-way calling, voice mail systems, call waiting and identification of applicant among others. Without However, there are occasions when subscribers of the mobile station nffli? ltianM Í * '«M > '"to' a, *.? ¿?., Aá < ...

(MS) are not available such as when the MS is busy on another call, switched off or has the battery exhausted When the MS is in that state, there is no uniform mechanism to inform the subscriber if an attempt to make contact has been made and if so, by whom. When the MS is active, the applicant identification services provide the advantage of identifying the requesting party for the receiving party before a call is accepted. This feature is especially advantageous for mobile station subscribers, as it imparts the ability to reject calls that are undesirable and waste monetary resources (as well as airtime). Similarly, voicemail systems are also very useful. When the subscriber is outside the service area, or turns off the phone, the requesting party can leave a message to the receiving party to call back later. Mobile subscribers are then free to review these messages at some later time. While the applicant identification and voice mail services are useful after a form, they also give rise to several limitations. For example, a subscriber who leaves his / her phone idle (ie switched off) for long periods of time can accumulate a number of messages in the voice mail storage. In order to determine the value of those messages, the subscriber is forced to use airtime in order to review each message one by one. . *. , -fc. i .L m. one. Therefore, potentially useless records may have been recorded and all must be listened to to determine their usefulness to the subscriber. Currently, there is no way to identify the calling party for an inactive mobile station, or the parties they select to leave messages in the voicemail instead of a direct connection to the receiving party. Therefore, what is needed is a system and method that identifies the parties requesting an inactive mobile station. Said system and method must provide a mechanism for retrieving a list of all the parties that establish calls to the idle subscriber telephone during periods of inactivity. In addition, if such parties select to leave voice mail messages, the system and method must provide a mechanism to indicate which of the requesting parties has chosen to leave a message and also compare the specific messages in the voice mail system with the identities of specific requesting party. Such a solution to the limitations of the current applicant and voicemail identification systems provides the advantage to the users of being able to activate a mobile telephone and immediately identify the requesting parties that have tried to reach the subscriber during the inactive period. In addition, any voice mail messages left to the subscriber are immediately identified without using airtime.

BRIEF DESCRIPTION OF THE INVENTION A system that identifies the parties requesting an inactive mobile station includes an initial position register (HLR) which has a memory and database to store the categories, classes, subscriber status (ie, active or inactive) and other data. The conventional database is expanded by the present invention to include a memory or record for storing a list of telephone numbers or other identifying information related to the unsuccessful requesting parties (ie, those requesting parties attempting to reach the MS inactive). The system also includes the inactive MS that has a second memory and, upon activation, is capable of storing the list of unsuccessful requesting party telephone numbers maintained by the HLR. The list of numbers is commonly sent to the MS by means of a mobile switching center (MSC) and the radio base station (BS) on the air interface. The list received by the MS subscriber allows a scrolling for review. This allows the subscriber to decide which subscriber calls to return. The system may also comprise a voice mail system, in which case the subscriber will also be informed of the unsuccessful requesting parties that have selected to leave a message to call back later. The method of identifying parties trying to make contact with an inactive MS comprises the steps of activating the MS, iti-.i; _- .. i A * -a- i-aaé a or Mi $ X. send a registration message to the associated MSC for authentication of the MS by the H LR, send the list stored in the memory of the HLR to the MSC, and in turn, send the list to the MS on the air interface as a separate of the record notification return result message. The method may also include the initial steps of sending a request request message from the requesting party to the HLR which identifies the requesting party by its telephone number, stores the number in the HLR memory and sends a message back to the requesting party. the requesting party to indicate the inactive status of the MS. The method for identifying unsuccessful requesting parties may also include the steps of sending a voice mail message query to the requesting party to determine whether a voice mail message will be recorded, storing any resulting message in the mail system of voice, store an indexed voice mail message indicator for the telephone number (or other information, such as the EIN) that identifies the requesting party and possibly store the requesting party's telephone number in the voice mail system with the message Finally, the method, when combined with the use of a voicemail system, can include interrogation of the voicemail system using the HLR to compare the voicemail messages of the requesting party recorded with the telephone numbers of the unsuccessful requesting parties. So, i * í? ttm A.2 to ***. . ^ a voice mail message indicator may be produced by the HLR, noting that a transfer has been made to the voice mail system or alternatively, the interrogation of the voice mail system by the H LR may be used to compare the messages within the voice mail system with the corresponding telephone numbers within the list of successful requesting parties maintained by the HLR.

DETAILED DESCRIPTION OF CURRENTLY PREFERRED ILLUSTRATIVE MODALITIES The system and method of the present invention can be more easily understood by dividing them each into two parts. The first deals with a requesting party attempting to make contact with an inactive mobile station, and the second involves the process used to retrieve a list identifying such parties when the mobile station is reactivated. Turning now to Figure 1, the system and method of the present invention operating in conjunction with the activities of an unsuccessful requesting party can be observed. The mobile station (MS) 20 typically comprises a cellular exchange which the requesting parties attempt to contact. The MS 20 includes a memory 30 for storing a list of requesting parties that attempt to make contact during periods of inactivity, but are not successful. This failure to make contact occurs when the MS 20 is "inactive", defined for the purpose of this invention as t ati-a-aS A.a.1 any operating state where the MS 20 does not act to provide a complete communication path between the requesting party and the receiving party. Therefore, an inactive mobile station may be one that is off, has a dead battery, or is located outside the service area. The memory 30 may be non-volatile, requiring the operator of the MS 20 to specifically instruct the deletion of the list, or it may be a volatile memory that maintains the contents of the list of unsuccessful requesting parties only while the MS 20 is activated. The MS 20 also provides the ability to erase the list held in the volatile memory by pressing the CLEAR key of the keyboard; the individual records of the list or the complete list can be deleted in this way. The arrow keys on the MS 20 keyboard provide a mechanism to scan the list and review attempts to make contact with the MS 20 during idle periods and, if desired, to dial a number that is on the list. The home location register (HLR) 50 also includes a memory for tracking the attempted calls made to the MS 20. Typically, the HLR memory 60 will include a list of A-numbers; one for each attempt made by a requesting party to contact MS 20 while remaining in an inactive state. The telephone number list or A 70 number that will typically be included as part of the subscriber profile for the MS 20. Each time an attempt is made to take the MS 20 during a call attempt, the HLR 50 will review the status of the MS 20 (for example, a.td active or inactive) and if inactive, the HLR will store the telephone number of the requesting party 80 within the memory 50 reserved for this purpose. When the MS 20 is activated, the list 70 stored in the memory 60 will be sent to the MS 20, and stored in the memory 30. The mobile switching center (MSC) 40 is a telephone exchange that handles the call traffic (for example). example, communication between the public switched telephone network (PSTN) or the public land mobile network (PLM N) and the HLR 50. And it is typically combined with a radio base station (BS) 45. The MSC 40 transfers the data and the voice information to the receiving and requesting parties BS 45 (illustrated as BS 160 in Figure 2), transmits and receives signals on the air interface to the MS 20. The protocols of the current communication network, which include the data signaling messages will require the addition of proprietary parameters having available length and the type of character string to support the transmission of the list 70 from the MSC 40, through the BS 160 to the MS 20. Returning now to the detailed example of Figure 1, the requesting party or subscriber terminal A 80, which can operate through the PSTN or PLMN, attempts to call the MS 20 inactive The MSC 40 associated with the HLR 50 sends a location request message 10 which contains the telephone number identifying the requesting party A (e.g., the number A), and the telephone number identifying the inactive mobile station. (for example, the number B). The HLR 50 informs the MSC 40 of the inactive state of the MS 20 by means of a location result-request-return message 120 and then the number identifying the requesting party 80, for example, the number A, is stored in memory 60 to become part of the list comprising a plurality of unsuccessful requesting party telephone numbers 70. While list 70 may comprise telephone numbers, e.g., A numbers, list 70 may also comprise other types of telephone numbers. Identification information, such as the name of the requesting party or the date and time the call was made. Each attempt to call the inactive MS 20 by the requesting party 80 is registered in this way, while the MS 20 is inactive and a call setup operation can not be completed between the requesting party 80 and the MS 20. In case if the voice mail service is not available, the MSC 40 will inform the requesting party A that the MS 20 is inactive at step 130. However, if the voice mail is available, the system of the present invention includes a voice mail system (VMS) 90 with a memory 100 for storing messages, so that a sequence of messages can pass between the MSC 40 and the VMS 90 as a voice mail sequence of operations 140, as is well known in The technique. This will result in the storage of a voicemail message from the requesting party 80 in the VMS memory 100. In this embodiment of the invention, the VMS message storage memory area 100 is not used to store any information it connects to. the selected numbers specific to the list 70 with the selected or specific voice mail messages recorded by the VMS 90. Thus, only the voice mail messages, which may or may not correspond to the calls stored in the list 70, they are stored in the memory 100. When the inactive MS 20 is activated to produce an activated MS 150, the sequence of steps appearing in Figure 2 are followed by the system 10 of the present invention. The method that provides the identification of parties requesting the inactive MS 20 comprises the steps of activating the inactive MS 20 to produce an activated MS 150, which sends a registration notification message 180 to the MSC 170 via the BS 160 (the which may or may not be an integral part of MSC 170). Commonly the registration notification message 180 will be sent from the MS 150 to the BS 160 and in turn will be sent to the MSC 170 as a registration notification message 190. The message 190 will be authenticated by the HLR 50 at the stage 200, since the HLR 50 is in electronic communication with the MSC 170. At that time, if the authentication in step 200 is successful, the list 70 stored in the call storage memory 60 will be sent from the MSC 170 as part of a registration-notification-return-result message 230, which passes from the MSC 170, through the BS 160, and to the active MS 150. The list 70 is commonly sent as a part of the user profile in the step 210 from the HLR 50 to the MSC 170, although it may also be sent from the HLR 50 to a visitor location register (VLR) 220, for transmission as a part of a first registration-notification-result message 230 for the BS 160 and a segu log message-result-notification 240 for the active MS 150. In any case, the list 70 is then stored in the memory 30 of the active MS 150 in step 250. A VLR 220 will be involved in the scenario only when the MS 20 is registered in a non-home MSC (ie, in a visited MSC) .

A more sophisticated version of the system 10 of the present invention, together with the method that provides the identification of parts requesting an inactive mobile station 20, can be seen in Figure 3. In this embodiment of the invention, voice mail is available and is provided by a VMS 90 with a memory 100 for message storage. The contact process attempted by the requesting party 80 of the inactive MS is the same as that illustrated in Figure 1. However, in this case, the MSC 40 provides a voice mail query 260 to the requesting party 80 to ask If the requesting party 80 chooses to leave a voice mail message in the VMS 90, if so, the voice mail messages of the requesting party are stored in the memory 100, which is adapted to store a selected number of messages from the requesting party. mail. In this mode, a number that identifies the requesting party stored in the £ x á, .. memory 60, such as a number 75 selected, together with a voice mail message indicator 77 (eg, an asterisk character "*"). Typically, the indicator 77 will be indexed for the number identifying the requesting party, for example, the selected number 75. The process of storing the voicemail message by the requesting party 80 is observed in figure 3 in step 270 , where the control is transferred from the MSC 40 to the VMS 90. In addition, a note message VMS 280 can be sent from the MSC 40 to the HLR 50 to pass the telephone number identifying the requesting party A 80 (for example the number A) and the applicant number identifying the inactive MS 20 (e.g., the number B) for the HLR 50 for storage and comparison with a particular message stored in the VMS memory 100 for subsequent calling. Once the message 280 is sent to the HLR 50, a result-return-note-response message 290 is sent from the HLR to the MSC 40, confirming that a voicemail message has been stored in the memory 100. , as well as the message indicator 77 in the memory 60. This particular mode is preferred for use when a manufacturer provides the HLR 50 and the VMS 90 as a single unit. In this case, there is no need to directly link the requesting party voice mail messages recorded in the memory 100 with those selected from the plurality of unsuccessful requesting party telephone numbers stored in the memory 60; the observation message VMS 280 provides a mechanism for comparing the identification numbers in the list 70 with the messages stored in the memory 100. Another implementation of the system 10 can be seen in figure 4, where a VMS 90 is available for use of the requesting party 80, and the identification telephone numbers for unsuccessful requesting parties 80 are stored both in the memory 60 and in the VMS memory 100. In this case, after the voice mail inquiry message 260 is sent to the requesting party 80, and with an affirmative answer, a control transfer from the MSC 40 to the VMS 90 is done in the step 370. The number identifying the requesting party 80, such as the number A, is sent within the message control signaling signal in step 370. The voice mail message and the number A (together with the number B of the MS 20) are stored simultaneously in the memory 100 in the step 300. Thus, at this point, the HLR 50 has a list of unsuccessful requesting party telephone numbers 70 stored in its memory 60 and the VMS 90 has a corresponding set of stored and indexed telephone numbers to correspond directly to the messages of voice mail in its memory 100. Typically, each set of messages will be identified with a time and date stamp in both memories 60 and 100. When the MS 20 is activated to produce an activated MS 150 in step 310, a registration notification message 320 is sent from the MS 150 to the HLR 50. In this case, the HLR interrogates the VMS 90 using the telephone number identifying the MS 150, for example, the number B, to determine which of the recorded requesting party voice mail messages stored in the memory 100 is compared to the selected numbers of the plurality of unsuccessful requesting party telephone numbers stored in the memory 60. Those compared numbers are returned as a list in the message interrogation-return-result 340 so that the HLR list 70 can be updated to include a sub-list of the unsuccessful requesting party telephone numbers 75, eg, A numbers with corresponding voicemail message indicators 77 This update process occurs in step 350, and the active MS 150 will notify its user by announcing or displaying a message waiting for the message. saje who tries to have been made to contact the MS 150 when he remained in an inactive state. In this implementation of the invention, the VMS 90 stores the voicemail messages in the memory 100 together with a label, such as the telephone number of the unsuccessful requesting party or other identification information. For the purposes of this invention, the "number identifying the requesting party" may comprise a telephone number, an A number, the date of the call, the time of the call, the name of the requesting party or other identification information. which may be useful for the subscriber of the MS to make use of the applicant identification service for inactive mobile stations.

As noted above, the most basic implementations of the present invention involve simply saving a list of unsuccessful requesting parties within the HLR memory 60 for downloading to the activated MS 150 sometime after the activation. For circumstances that include those occasions when the mobile station is off, or have an exhausted battery, only feeding the MS 150 will result in the production of a registration notification message 180, 320 to authorize a return-result message that provides a list 70 for the 10 MS 150. In this case, the system 10 identifying the parties calling an inactive MS comprise the HLR having a first memory 60 adapted to store a list 70 containing a plurality of unsuccessful requesting party telephone numbers and the MS 20 including a second memory 30 adapted 15 for storing the list 70. The numbers in the list 70 may comprise numbers A and the location request message 1 10 results from an unsuccessful requesting party call set-up request directed towards the inactive MS 20 indicates to the HLR 50 that stores a phone number that identifies the party 20 applicant in the first memory 60. Once the inactive MS 20 is activated, and a registration notification message 320 is sent from the MS 150 to the domestic MSC or service MSC 170, in electronic communication with the HLR 50 , the HLR 50 is indicated to send the list 70 to the domestic or service MSC 170 I m1m mmmm. . A A t r m r * r. í.

Subsequent storage in the second memory 30 within the MS 150. If a voice mail system is included within the system 10 of the present invention, the VMS 90 will have a third memory 5 100 adapted to store a number of mail messages of voice along with a number of unsuccessful requesting party telephone numbers. Typically, the number of stored voicemail messages will be greater than or equal to the number of unsuccessful requesting party telephone numbers stored in memory 100. The VMS 90 will typically index voice mail messages and unsuccessful request party telephone numbers according to the telephone number identifying the inactive mobile station, for example, the number B. The second memory 30 within the MS 20, 15 150 may include a voicemail message indicator 77 stored for those selected from the plurality of unsuccessful requesting party telephone numbers, comprising a sublist 75. The method of providing an identification of parts that 20 requesting an inactive MS 20 may be as simple as activating the inactive MS 20 to produce an activated MS 150, which sends a registration notification message 180, 190 from the activated MS 150 to a first MSC 170, which authenticates the message of registration notification 180, 190 using an HLR 50 in electronic communication 25 with the MSC 170, wherein the HLR 50 includes a first memory 60 i ffií¡¡¡J ^ ^ ^ - ^ adapted to store a list 70 comprising a plurality of unsuccessful requesting party telephone numbers; sending the list 70 stored in the first memory 60 from the H LR 50 to the VLR 220; send the list 70 from the VLR 220 to an MSC 150 in electronic communication with the MS 150 activated; and sending a registration-notification-return-result message 230, 240 which includes the list 70 for the activated MS 150 from the MSC 150. The method may further comprise the steps of sending a location request message 110 from a second MSC 40 in electronic communication with a requesting party 80 for the HLR 50 which includes a number identifying the requesting party 80 and a number identifying the inactive MS 20. Of course, the first MSC 170 may be the same as the second MSC 40. If the MS 20 is inactive, the number identifying the requesting party is stored in the first memory 60 and a location-request-return-result message 120, which includes the status of the inactive MS 20, is sent from the HLR 50 towards the second MSC 40. If voice mail is available, the method of the present invention may include sending a voice mail inquiry message 260 to the requesting party.; storing a voicemail message from the requesting party 80 in the VMS 90, which includes a second memory 100 adapted to store a first number of voicemail messages; store a number identifying the requesting party 80 in the first memory 60 inside . tLJL r L &? of the HLR 50, together with a voice mail message indicator 77 indexed for the number identifying the requesting party. Although the invention has been described with reference to specific embodiments, this description is not considered in a limiting sense.
