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.

Systems and methods for network-based identification of priority services

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).

System and method for communicating emergency information in an emergency call

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.

Systems and methods for redirecting an emergency callback to a contact of an emergency caller

In some implementations, an application server may receive, from a calling party user equipment, a call for a called party associated with multiple user equipment. The application server may provide to the multiple user equipment, and based on the call, a request for transcoding information associated with the multiple user equipment. The application server may assign a transcoding resource for handling the call, wherein the transcoding resource is provided in a network. The application server may receive, based on the request, the transcoding information from a particular user equipment of the multiple user equipment. The application server may provide the transcoding information to the transcoding resource, wherein the transcoding information causes the transcoding resource to establish and transcode the call between the calling party user equipment and the particular user equipment.

Systems and methods for reducing transcoding resource allocation during call setup to multiple terminations

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.
