Abstract: In the various embodiments, systems and methods are disclosed for providing unique service and location codes from a user of a mobile device to a Public Safety Answering Point (PSAP) operator at the beginning of an emergency call. In some embodiments, the unique location codes can be utilized in routing the of the emergency call to the appropriate PSAP. In the embodiments, the unique codes can be received as part of an SIP INVITE message including a modified P-Access-Network-Info (PANI) header forwarded from a Proxy-Call Session Control Function (P-CSCF) to an Emergency Call Session Control Function (E-CSCF).

Abstract: A device may determine that a failure occurred in an emergency call between a public-safety answering point (PSAP) and a first user device associated with an emergency caller, and may identify, based on determining the failure, one of a first option, a second option, or a third option for redirecting an emergency callback to a contact of the emergency caller. The device may cause, when the first option is identified, the emergency callback to be redirected to a second user device associated with the contact of the emergency caller, and may cause, when the first option is identified, a bearer path to be established between the PSAP and the second user device for the emergency callback.

Abstract: A network device may receive, from a user device, a call associated with a telephone number, where the call is intended for a priority service associated with the telephone number. The network device may identify the call as a priority call based on the telephone number associated with the call, and may determine that a network overload condition exists. The network device may associate a priority tag with the call based on identifying the call as a priority call. The network device may cause the call to be provided preferential treatment, while the call is transmitted for the priority service during the network overload condition, based on the priority tag.

Abstract: A method may include determining that a digit pattern has been input on a user device to initiate a call; transmitting the digit pattern to a device that stores a list of digit patterns to which calls are not to be completed; receiving, from the device, data that indicates whether the digit pattern is on the list of digit patterns; prohibiting the call from being initiated with a network when the data indicates that the digit pattern is on the list of digit patterns; and initiating the call with the network when the data indicates that the digit pattern is not on the list of digit patterns.
