Abstract: Uplink congestion control based on session initiation protocol (SIP) messaging includes receiving SIP messages from user equipment devices (UEs) via established wireless uplink connections; and monitoring a rate of the SIP messages received from the UEs. Uplink congestion control further includes identifying whether the rate of received SIP messages exceeds a first threshold during a first period of time; and sending SIP response messages to the UEs to reduce congestion on the wireless uplink connections upon identifying that the rate of received SIP messages exceeded the first threshold over the first period of time, where the sent SIP response messages instruct the UEs to resend the SIP messages after predetermined time delays.

Abstract: A method for paging priority and wireless access which includes receiving, at a base station and from a core network, a paging message associated with a priority connection from a first user equipment device (UE) having an elevated priority status, to a second UE having a non-elevated priority status. The method further includes determining, at the base station, that non-elevated priority wireless access channels are congested, detecting, at the base station, a priority indicator within the received paging message in response to determining that the non-elevated priority wireless access channels are congested. The method further includes caching, at the base station, an identifier of the second UE in response to detecting the priority indicator in the received paging message, and establishing a wireless connection between the first UE and the second UE upon verifying that the identifier of the second UE has been cached.

Abstract: A system described herein may provide a technique for providing high priority access to one or more particular priority cells implemented by a base station of a radio access network (“RAN”) associated with a wireless telecommunications network. A first group of User Equipment (“UEs”) may be High Priority Access (“HPA”) UEs, and a second group of UEs may be non-HPA UEs. In response to triggering events, system broadcast messages and/or Radio Resource Control (“RRC”) release messages may be used to cause HPA UEs to connect to the priority cells, and may cause non-HPA UEs to connect to other (e.g., non-priority) cells implemented by the base station.

Abstract: A system described herein may provide for the prioritization of Session Initiation Protocol (“SIP”) messages, transmitted by a User Equipment (“UE”), based on a priority class indicator (“PCI”) included in a registration message (e.g., a SIP REGISTER message) from the UE. The PCI may be included in a contact header, a SIP contact Uniform Resource Identifier (“URI”), and/or some other portion of the registration message. A Universal Integrated Circuit Card (“UICC”) may store information indicating the priority class (e.g., in an Access Control Class (“ACC”) Elementary File (“EF”)). One or more network components, such as a Call Session Control Function (“CSCF”) may prioritize SIP messages from the UE based on the priority class indicator included in the registration message by the UE.

Abstract: A method, a device, and a non-transitory storage medium are described in which a Wi-Fi admission control and prioritization service is provided. The Wi-Fi admission control and prioritization service may be included in a Wi-Fi access device. The Wi-Fi admission control and prioritization service may include the Wi-Fi access device reserving Wi-Fi data connections for priority users. An end device may transmit priority information to the Wi-Fi access device during a Wi-Fi connection establishment procedure. The Wi-Fi access device may use one of the reserved data connections to establish a Wi-Fi connection with the end device. The priority information may include a non-Wi-Fi access control class value that indicates the end device is of a high priority. The Wi-Fi access device may provide quality of service and prioritization, which is in correspondence to the priority information, to traffic of the end device that traverses the Wi-Fi access device.

Abstract: Systems and methods implement prioritized IP Multimedia System (IMS) registration procedures for Emergency and Priority Service users. A network device in an IMS network, receives, from a user equipment device, a Session Initiation Protocol (SIP) Register message that includes a priority indication. The network device detects the priority indication in the SIP Register message and provides, based on the priority indication, priority registration for the user equipment device when the network device is in an overloaded condition.
