Systems, devices, and techniques described herein relate to efficient Evolved Packet System (EPS) fallback. A method may include receiving a rejection message that indicates a rejection to set up a call through a 5th Generation (5G) network by a 5G Radio Access Network (RAN). In response to receiving the rejection message, the method may include transmitting a request to establish a dedicated bearer through a 4th Generation (4G) network. A confirmation that the second dedicated bearer has been established through the 4G network may be received within a predetermined time after transmitting the request.

A session initiation protocol register request message for RLOS can be received at a P-CSCF. The session initiation protocol register request message can include an IP multimedia public user identification for a UE. The session initiation protocol register request message can be forwarded to a Serving Call Session Control Function (S-CSCF). A UE identifier in a 200 OK response can be received in response to forwarding the session initiation protocol register request message at the P-CSCF from the S-CSCF. Signaling can be ciphered using a security key for the UE in response to receiving the 200 OK response.

Systems and methods are disclosed for client-based control of revising caller identifications (IDs) for communications between a private network and a public network. An apparatus including a communications provider server and processing circuit that communicates client-specific sets of data over an interface protocol. The telecommunications-providing server revises a caller ID for a call based on the client-specific sets of data, an identifier that corresponds to a requesting endpoint, and a geographic region determined from the call request. Further, the telecommunications-providing server connects the VoIP call by accessing and passing a provisioned number. The provisioned number includes the revised caller ID which is a local number identified by the determined geographic region that the endpoint is located.

A method for implementing a generic routing encapsulation (GRE) tunnel, an access point (AP), and a network system. The method includes establishing a Control And Provisioning of Wireless Access Points (CAPWAP) tunnel with an access controller (AC), receiving addresses of at least two gateways, establishing at least two GRE tunnels coupled to the gateways respectively according to the addresses of the at least two gateways, and selecting one of the at least two GRE tunnels to transmit data.

A method and a device for managing a remote communication service (streaming) between a terminal in a communications network and an object of a local area network. The terminal and the object are capable of communicating via a gateway of the local area network. The method includes the following steps on a service provision device providing the service: establishing a list of associations between an address for accessing the object and at least one feature of the service; obtaining at least one criterion linked to the terminal; selecting at least one association in the list of associations according to said criterion; and sending to the terminal at least one address associated with said at least one selected association.

Systems, devices, and methods for media processing and streaming, including transmitting, by a 5G media streaming uplink (5GMSu) application provider (AP), a request to create a provisioning session for 5GMSu streaming using a 5GMS system; receiving, by the 5GMSu AP, an acknowledgement corresponding to the provisioning session; and performing, by the 5GMSu AP, a 5GMSu egest operation corresponding to the 5GMSu streaming, wherein the 5GMSu AP is included in an external data network (DN) which is external to the 5GMS system.

A network device for a mobile carrier network sends, to a third-party content platform, a client message including a first dedicated subscription parameter extension. The first dedicated subscription parameter extension indicates one or more subscription parameters for a data flow between a user equipment (UE) device that originated the client message and the third-party content platform. The network device receives, from the third-party content platform, a server message including a second dedicated subscription parameter extension. The second dedicated subscription parameter extension confirms the third-party content platform will abide by the one or more subscription parameters. The network device generates, based on the one or more subscription parameters, a policy enforcement rule for the data flow that relies, at least in part, on cooperation of the third-party content platform.

Devices, systems, and methods relate to performing Internet Protocol (IP) Media Subsystem (IMS) bearer activation and radio bearer activation at different times. In some embodiments, a radio bearer is activated after the IMS bearer is activated. The radio bearer that is activated after the IMS bearer is activated may utilize a different Radio Access Technology (RAT) than an initial radio bearer. In certain instances, a device initiates activation of the radio bearer upon receiving confirmation that the IMS bearer is activated, or initiates activation of the radio bearer a predetermined period of time after initiating activation of the IMS bearer. In various embodiments, staggered IMS bearer activation and radio bearer activation can prevent collisions at components of an Evolved Packet Core (EPC).

A gateway device includes a call handling equipment (CHE) listener interface, an Internet Protocol (IP) interface, a provisioning engine, and a message parsing engine. The CPE listener interface forms a communication channel with a CHE and receives call event data from the CHE. The IP interface communicates with a cloud-based processing system. The provisioning engine receives, from the cloud-based processing system via the IP interface, instructions for parsing data from a data output format of the CHE into a consistent data format of the cloud-based processing system. The message parsing engine parses the call event data received from the CHE via the CHE listener interface, and formats the call event data according to the consistent data format. The gateway device transmits the formatted call event data to the cloud-based processing system via the IP interface.
