Abstract

Aspects of the subject disclosure may include, for example, a device, comprising: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising: detecting that a 911 call had been made on a carrier network by the device, the device having associated therewith a telephone number; responsive to the detecting that the 911 call had been made, sending a token to the carrier network, the token causing the carrier network to disable call blocking to the telephone number. Other embodiments are disclosed.

Claims (31)

1 . A device, comprising:

a processing system including a processor; and

a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:

detecting that a 911 call had been made on a carrier network by the device, the device having associated therewith a telephone number; and

responsive to the detecting that the 911 call had been made, generating, by the device, a token and sending the token to the carrier network, the token causing the carrier network to temporarily disable all types of call blocking, wherein the all types of call blocking includes both private-network call blocking and network-level call blocking, wherein the private-network call blocking includes a Local Call Blocking Instance (LCBI) comprising a database of call blocking rules defined by a private network operator, wherein the LCBI is synchronized with one or more carrier network call blocking databases, and wherein a period of time for disabling call blocking is determined based on a user profile associated with the device and the rules stored in the LCBI database.

2 . The device of claim 1 , wherein the device comprises a smartphone, a cellphone, a tablet computer, a laptop computer, or any combination thereof.

3 . The device of claim 1 , wherein the device communicates with the carrier network using licensed radio spectrum.

4 . The device of claim 3 , wherein the licensed radio spectrum comprises a 4th generation (4G) radio spectrum, a 5th generation (5G) radio spectrum, a subsequent generation radio spectrum, or any combination thereof.

5 . The device of claim 1 , wherein the detecting comprises detecting that a user of the device had dialed 911.

6 . The device of claim 1 , wherein the 911 call is made to a public safety answering point (PSAP).

7 . The device of claim 6 , wherein the disabling of the call blocking to the telephone number allows a return call from the PSAP to be connected back to the device.

8 . The device of claim 1 , wherein the token causes the carrier network to disable the call blocking to the telephone number for a temporary time period, after which the call blocking is no longer disabled.

9 . A non-transitory machine-readable medium comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:

receiving a 911 call from a mobile communication device via a carrier network;

detecting, based upon the 911 call that is received, a telephone number of the mobile communication device; and

sending, to the carrier network, a token that is associated with the telephone number of the mobile communication device, the token causing the carrier network to disable call blocking for the telephone number of the mobile communication device, the token causing the carrier network to temporarily disable all types of call blocking, wherein the all types of call blocking includes both private-network call blocking and network-level call blocking, wherein the private-network call blocking includes a Local Call Blocking Instance (LCBI) comprising a database of call blocking rules defined by a private network operator, wherein the LCBI is synchronized with one or more carrier network call blocking databases, and wherein a period of time for disabling call blocking is determined based on a user profile associated with the mobile communication device and the rules stored in the LCBI database.

10 . The non-transitory machine-readable medium of claim 9 , wherein the processing system is part of a public safety answering point (PSAP).

11 . The non-transitory machine-readable medium of claim 10 , wherein the disabling of the call blocking to the telephone number allows a return call from the PSAP to be connected back to the mobile communication device.

12 . The non-transitory machine-readable medium of claim 11 , wherein the token causes the carrier network to disable the call blocking to the telephone number for a temporary time period, after which the call blocking is no longer disabled.

13 . The non-transitory machine-readable medium of claim 9 , wherein the token is cryptographically tied to the telephone number of the mobile communication device.

14 . The non-transitory machine-readable medium of claim 9 , wherein the carrier network uses licensed radio spectrum.

15 . The non-transitory machine-readable medium of claim 14 , wherein the licensed radio spectrum comprises a 4th generation (4G) radio spectrum, a 5th generation (5G) radio spectrum, a subsequent generation radio spectrum, or any combination thereof.

16 . The non-transitory machine-readable medium of claim 9 , wherein the mobile communication device comprises a smartphone, a cellphone, a tablet computer, a laptop computer, or any combination thereof.

17 . A method, comprising:

detecting, by a processing system of a private core network including a processor, dialing of a 911 call from a mobile communication device in communication with the private core network, the mobile communication device being in communication with the private core network via citizen band radio spectrum (CBRS), the private core network comprising a database of incoming call blocking rules;

facilitating, by the processing system, communication connection of the mobile communication device to an emergency response center via the private core network; and

updating, by the processing system, the database to comprise a rule that disables all types of call blocking, wherein the all types of call blocking includes both private-network call blocking and network-level call blocking, by the private core network of a return call from the emergency response center to the mobile communication device, wherein the private-network call blocking includes a Local Call Blocking Instance (LCBI) comprising a database of call blocking rules defined by a private network operator, wherein the LCBI is synchronized with one or more carrier network call blocking databases, and wherein a period of time for disabling call blocking is determined based on a user profile associated with the device and the rules stored in the LCBI database.

18 . The method of claim 17 , wherein:

the rule disables call blocking by the private core network of a return call from the emergency response center to the mobile communication device for a temporary time period, after which the call blocking by the private core network of a return call from the emergency response center to the mobile communication device is no longer disabled.

19 . The method of claim 17 , wherein the emergency response center comprises a public safety answering point (PSAP).

20 . The method of claim 17 , wherein the return call from the emergency response center is made in response to the 911 call from the mobile communication device having been dropped.
