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

A device obtains configuration parameters for multiple network elements of a network and receives first scores that assess a level of efficiency and a level of isolation for each of the multiple network elements. The device identifies a network element of the multiple network elements for modifying the identified network element's configuration based on the obtained configuration parameters and the received first scores.

A device may receive, from a user device, a request to establish a voice call. The device may determine that one of a plurality of endpoints is to be involved in the voice call with the user device. The device may transmit send-only invites to the plurality of endpoints. The device may receive, from a first endpoint of the plurality of endpoints, a receive-only response. The device may transmit a send-receive invite to the first endpoint, wherein the send-receive invite identifies a selected communication protocol as a communication protocol for the voice call. The device may transmit a send-receive acceptance to the user device. The send-receive acceptance may identify the communication protocol for the voice call, and upon the user device receiving the send-receive acceptance, the voice call can be established between the user device and the first endpoint.

Systems and methods provide on-demand network slicing to support testing of customer use cases A test network management system receives customer parameters for a use case in a production network. The customer parameters include an identifier for a user equipment (UE) device to be tested with the use case. The test network management system provides, to the UE device, configuration information to associate the UE device with a test mode network segment of the production network. A network device in the production network may receive a registration request, from the UE device, that includes the configuration information. Based on the configuration information, the network device blocks the UE device from accessing the production network. Instead, the test network management system initiates provisioning of the test mode network segment for the UE device; and the network device redirects the registration request to the test mode network segment.

Systems and methods of using network slicing for test platform

A device receives personality profiles sent from multiple network elements of a network and obtains configuration parameters for each of the multiple network elements from the personality profiles. The device receives first scores generated for the multiple network elements, where each of the first scores relates to assessing a usefulness status of a respective one of the multiple network elements. The device identifies a network element of the multiple network elements for modifying the identified network element's configuration based on the obtained configuration parameters and the received first scores.

A network node receives a registration message, where the registration message is associated with registering a user equipment (UE) with a call signaling network for sending or receiving calls. The network node receives a notification message from a call session control node in the call signaling network, where the notification message indicates whether the UE is currently provisioned to engage in calls via a Voice over Long Term Evolution (VoLTE) network. The network node causes calls to or from the UE to be routed via the VoLTE network if the notification message indicates that the UE is currently provisioned to engage in calls via the VoLTE network, and causes calls to or from the UE to be routed via a legacy network, that is different than the VoLTE network, if the notification message indicates that the UE is currently not provisioned to engage in calls via the VoLTE network.
