Abstract
Calls from a phone identified as being a source of harassing or other undesirable phone calls are blocked at a mobile positioning center (MPC). Upon request by the PSAP, a call record detail can be obtained from the MPC revealing a simulated “callback phone number”. The MPC then intercepts all future incoming calls from that simulated callback phone number and routes them to a recording that advises the harasser that the phone has been identified as a harasser and is now blocked. The recording can also advise the caller how to restore service. In a preferred embodiment, the MPC sets a timer to automatically restore service after a designated length of time.
Description
- This application claims priority from U.S. Provisional Appl. No. 60/684,554, filed May 26, 2005, entitled “E911 Call Blocking For Non-Initialized Wireless Telephones”, by Richard Dickinson, the entirety of which is expressly incorporated herein by reference.
- 1. Field of the Invention
- This invention relates generally to wireless services. More particularly, it relates to E911 wireless services.
- 2. Background of the Related Art
- The FCC has mandated that all wireless telephones must be able to dial 9-1-1, even if other service is denied. This includes uninitialized phones (i.e., cellular phones that have not yet been activated by the wireless carrier). Uninitialized phones have no assigned phone number and are virtually untraceable. Because of this, they have become a popular way for mischief-makers to place hundreds or thousands of harassment calls to Public Safety Answering Points (PSAPs), thereby compromising the ability of the PSAPs to respond to real emergencies.
-
FIG. 3 shows conventional elements relating to routing of an E911 call from a cell phone. - In particular, as shown in
FIG. 3 , a conventional wireless carrier's mobile switching center (MSC) 502 contacts a Mobile Positioning Center (MPC) 504 to ascertain proper routing of an E911 call. The MPC 504 responds with routing information and the MSC 502 then routes the call to thecorrect PSAP 208. The MPC 504 stores the caller's call-back number and location in a dynamic database and relays that information to the PSAP 208 at the appropriate time. - Currently, uninitialized phones are identified only with a nonfunctional, simulated “callback” number that consists of a portion of the phone's electronic serial number (ESN). The FCC has authorized wireless carriers to terminate service to these phones if the PSAP identifies the phone as a harrasser. Some MSCs are capable of blocking single ESNs, while others are less flexible and must block all uninitialized phones. The effort to block these calls at the MSC 502 is time consuming and troublesome.
- Thus, disadvantages of the current solutions include: (1) It requires time consuming manual intervention to block identified calls; (2) Once a call is blocked, it remains blocked until a technician manually restores service; and (3) Some wireless switches cannot block individual telephones.
- Moreover, once blocked, the subsequent legitimate user of the phone is not advised that the phone has been blocked.
- There is a need for improved technology for blocking E911 calls from a non-initialized wireless telephone deemed to have previously been used to make a harassing or illegitimate call to 9-1-1.
- In accordance with the principles of the present invention, a method of blocking an undesirable call from being routed to an intended recipient comprises associating a simulated callback phone number with the undesirable call. A mobile positioning center (MPC) is queried for routing instructions for the undesirable call. The simulated callback phone number is compared with a known list of callback phone numbers to be blocked. If a match is made by the comparing, routing of the undesirable call to the intended recipient is blocked at the mobile positioning center (MPC).
- Apparatus for blocking an undesirable wireless call from being routed according to yet another aspect of the invention comprises a blocked phone number list maintained by a mobile positioning center (MPC). A module compares a callback number associated with a received query for routing instructions to entries in the blocked phone number list. If a match is made between the callback number and an entry in the blocked phone number list, routing to an intended destination is refused.
-
FIG. 1 shows exemplary network elements relevant to call blocking for E911 harassment calls, in accordance with the principles of the present invention. -
FIG. 2 shows exemplary messaging to accomplish call blocking for E911 harassment calls, in the exemplary system shown inFIG. 1 . -
FIG. 3 shows conventional elements relating to routing of an E911 call from a cell phone. - In accordance with the principles of the present invention, calls from a phone identified as being a source of harassing or other undesirable phone calls are blocked at a mobile positioning center (MPC), rather than at the MSC as in conventional systems. Upon request by the PSAP (e.g., a PSAP designated as servicing the location from which the harassing call originates or is registered in), a call record detail can be obtained from the MPC revealing a simulated “callback phone number” of the mobile phone identified to have made a harassing call. The MPC then intercepts all future incoming calls from that phone corresponding to the simulated callback phone number, and routes this and any future calls therefrom to a recording that advises the harasser that the phone has been identified as a source of harassing phone calls and is now blocked. The recording can also advise the caller how to restore service. In a preferred embodiment, the MPC sets a timer to automatically restore service after a designated length of time.
-
FIG. 1 shows exemplary network elements relevant to call blocking for E911 harassment calls, in accordance with the principles of the present invention. The disclosed wireless infrastructure is implemented to support subsequent 9-1-1 calls. - In particular, as shown in
FIG. 1 , amobile phone 173 communicates with a givencell site 174. Thecell site 174 communicates with a mobile switching center (MSC) 202 in a wireless carrier's network. The mobile switching center (MSC) 202 is the wireless equivalent to a landline end office. - Importantly, according to the invention, the MSC 202 includes a simulated callback
phone number module 202 a. The simulated callbackphone number module 202 a provides a simulated callback number for a given wireless phone calling 911. In the disclosed embodiments, the simulated callback number comprises “911” plus the last 7 digits of the ESN (totaling 10 digits). This format is typical per current industry standards, but can be modified in any manner that uniquely identifies the telephone. - An appropriate
mobile positioning center 204 also communicates with the ALIdatabase 210 and the coordinate routing database (CRDB) 212. The mobile positioning center (MPC) 204 is the call routing “mastermind” that maintains a database of cellular towers and which PSAPs should receive calls from which cellular tower. The MSC 202 relies upon the MPC 204 to determine which selective router should receive the E911 call. The MPC 204 also communicates with the PSAP 208 to inform thePSAP 208 of the caller's phone number and address. -
FIG. 2 shows exemplary messaging to accomplish call blocking for E911 harassment calls, in the exemplary system shown inFIG. 1 . In particular, as shown inFIG. 2 , an initial harassing call is placed from the uninitializedmobile phone 173 through a givencell site 174. The wireless harassment call is eventually designated as a harassing call, and handled appropriately. - As shown in
step 101 ofFIG. 2 , the receiving cell site routes the 911 call to the MSC 202. The MSC 202 receives the call. - In response to receipt of the E911 wireless call, the simulated callback
phone number module 202 a is activated, and in response appends a 10-digit simulated callback phone number to the E911 call (“911” plus the last 7 digits of the ESN of the unitialized phone.) - The MSC 202 then queries the
MPC 204 for call routing instructions for the E911 call, which at that point includes the 10-digit simulated callback phone number. Preferably, the query from the MSC 202 includes not only the simulated callback number (911+last 7 digits of the ESN), but also the cellular tower from where the call originated. - Thus, the MSC 202 queries the
MPC 204 for call routing instructions, and provides to theMPC 204 the simulated callback number acrossdedicated data circuits 102. Preferably, the query from the MSC 202 includes not only the simulated callback number (911+last 7 digits of the ESN), but also the cellular tower from where the call originated. The MPC queries the HarrasserNumber Data Base 216 to see if the simulated callback number is listed. In the absence of a match in theHarrasser Number Database 216, theMPC 204 queries a coordinate routing database (CRDB) 212, which determines that calls originiating from which cell towers should be routed to which PSAPs. - As shown in
step 102, upon determining the appropriate PSAP to receive the call, theMPC 204 responds with appropriate call routing instructions. These instructions consist of a pseudo automatic number identifier (pANI) that relates to a specific trunk group 103 (e.g., CAMA or SS7 voice trunk) between theMSC 202 and theselective router 206. This pANI is, e.g., a 10-digit number compatible with the existingselective router 206 that serves thatPSAP 208. The ESRK is preferably unique to thatPSAP 208. - In
step 103, theMSC 202 directs the 911 call to the designatedselective router 206 via the identifiedtrunk group 103. The E911 call is routed to the appropriate public safety answering point (PSAP) via theselective router 206, which has been provisioned to relate the specified pANI to aspecific trunk group 104 that connects theselective router 206 to the intendedPSAP 208. - In
step 104, upon receipt of the emergency call with the specified pANI, theselective router 206 delivers the call using existing E911 infrastructure to thePSAP 208. Theselective router 206, previously provisioned as is otherwise conventional to recognize the pANI in the ANI field of the CAMA or SS7 voice call, routes the call to the appropriate PSAP. - In
step 105, per current existing technology, thePSAP 208 receives the voice call and using the pANI, queries theASI database 210 for the location and call-back information. TheALI database 210 steers the pANI to theappropriate MPC 204, which responds to the ALI query with the simulated “callback” number of the originating phone. - Thus, the E911 call continues on to an ANI/
ALI controller 275 or similar device within thePSAP 208, which communicates with an automatic location identifier (ALI)database 210, and ultimately on to a PSAP workstation manned by appropriate emergency personnel. TheALI database 210 is provisioned with the pANI so that queries using that pANI are routed to the MPC that initially issued the pANI. The ANI/ALI controller 275 queries theALI 210 for ALI data related to the pANI. TheALI 210 routes the query to theMPC 204 via existingdata circuits 105. TheMPC 204 responds with the simulated callback number of the uninitialized phone. - TCP/
IP data circuits 105 must be ordered and installed between theMPC 204 and thevarious ALI databases 210. - Web based
Graphical User Interface 107 with appropriate access restrictions must be installed at theHarrassment Number Database 216. This interface is used for the PSAPs to identify harassing telephones according to their simulated callback number. Alternatively, this communications can be verbal, via fax, or other device between authorized personnel at the PSAP and personnel managing theHarrasser Number Database 216. - In
step 106, the harasser harasses. For example, the harasser might merely breath heavily into the phone, whisper juvenile obscenities, whatever, and typically refuse to hang up. - In
step 107, the PSAP dispatcher terminates the call, and in accordance with the principles of the present invention, notifies theMPC 204 of the simulated “callback” number associated with a harassing or prank 911 phone call. - In
step 108, personnel at theMPC 204 list the reported simulated “callback” number in a suitable database of calls to be blocked from PSAPs in the future. The database may be a separate, special database, or may be integrated within a larger database. This database is represented by theharasser number database 216 shown inFIGS. 1 and 2 . - In a preferred embodiment, personnel at the
MPC 204 also assign a “timeout” period after which the simulated callback number that was listed in the harassing database is purged from the harassing database. At this point, thephone 173 would be free to call again, even as a harasser. However, given that a predefined period of time has elapsed since the last harassing call has been given from thatphone 173, it is unlikely that the original harasser would harass again from thephone 173. - The timeout period may alternatively be automatically set without the need for operator intervention. Secure IP interfaces may be made available to PSAP personnel who invoke the timeout period directly.
- As an alternative, rather than being purged, the callback number may be maintained in the blocked number database but de-activated or enabled in some way that maintains a record of the previous harassing 911 phone call made using that callback number. This allows normal operation of the wireless phone, but also a record of the undesirable harassing call made from that
phone 173. - In
step 109, the harasser might again dial 911. Again theMSC 202 activates the simulated callbackphone number module 202 a and appends a 10-digit simulated callback phone number to the 911 call. Again theMSC 202 routes the call to theMPC 204 per otherwise conventional processes. - However, this time, as shown in
step 110, theMPC 204 compares the simulated callback phone number associated with the latest E911 call to entries in theharasser number database 216. In the given scenario, this time theMPC 204 recognizes the simulated “callback” number in the special harassing 911 dialer'sdatabase 216. As a result, theMPC 204, this time, responds with routing instructions to a 10-digit PSTN number of a pre-recordedannouncement message element 279 instead of routing information to the otherwise designatedPSAP 208. - The pre-recorded message played by the
recording element 279 can, of course, be programmed to say anything. As an example, the pre-recorded message might state something like: “911 calls from this phone have been blocked because this phone has been identified by law enforcement authorities as a source of telephone harassment. To restore 911 service, please contact XYZ Wireless. Goodbye.” - In
step 111, after a given “timeout” period of time later (e.g., several hours, one or more days, etc. later), the relevant entry of the simulated callback number corresponding to the harassing 911 dialer'sphone 173 is automatically purged from theharasser number database 216, and normal 911 service is thus restored. Of course, a record of the phone having been listed in theharasser number database 216 along with pertinent information such as when the harassing call was made, the location of the phone when the harassing call was made, etc., may be recorded for later review by appropriate personnel. - Note that the inventive blocking technology will work to block calls from any wireless phone presumably desired not to be routed to a PSAP. The example of an uninitialized phone is used because uninitialized phones are the most commonly used type phones for harassment, and also are the most difficult to trace.
- The present invention provides technology that results in the reduction of the waste of 911 emergency service resources caused by prank or harassing 911 calls made from uninitialized wireless devices. In extreme emergencies where time saves lives, the present invention might also be credited with the capability of saving lives that might otherwise be lost due to the delay or even failure of a legitimate 911 caller from a wireless device to reach 911 responders caused while the
relevant PSAP 208 is tied up dealing with a prankster or harasser. - The principles of the present invention can also be implemented to route specific legitimate callers to specific 911 resources. For example, a person with a heart condition may purchase a special wireless phone solely for the purpose of dialing 911 in the event of a heart attack. At the prior request of the caller, their phone number may be maintained in a special database similar to the harassing 911 caller's
database 216. Then, in accordance with the principles of the present invention, any/all 911 calls made from that particular phone with a phone number previously entered into the special database can be routed directly to a medical responder or other designated phone (e.g., their surgeon, etc.) - While the invention has been described with reference to the exemplary embodiments thereof, those skilled in the art will be able to make various modifications to the described embodiments of the invention without departing from the true spirit and scope of the invention.
