  • Patent number: 11665212
    Abstract: Systems, devices, and techniques described herein relate to timer-initiated fallback. In an example method, a message associated with Quality of Service (QoS) sensitive services is received from a core network. In response to receiving the message, a timer is initiated. If the timer expires without having received a confirmation that a dedicated tunnel associated with the QoS-sensitive services has been established in the first core network, then a fallback process can be initiated.

  • Patent number: 11659469
    Abstract: A communication session for a UE can be restored in the event of serving call session control function (S-CSCF) node unavailability and/or application server (AS) unavailability by storing, prior to IMS unavailability, attribute-value pairs (AVPs) at a home subscriber server (HSS). These AVPs can be used independently by individual IMS nodes to restore a communication session for a UE due to an unavailable IMS node. When a first S-CSCF node becomes unavailable, a proxy CSCF (P-CSCF) node can send a SIP request originating from the UE to a second S-CSCF node. The second S-CSCF node can then send a request to the HSS for an identifier of an AS associated with the UE. Upon receipt of the AS identifier (e.g., an active AS name AVP) from the HSS, the second S-CSCF node can send the SIP request to the AS in order to restore the communication session for the UE.

  • Publication number: 20230060074
    Abstract: Systems, devices, and techniques described herein relate to intelligently allocating network resources to Quality of Service (QoS)-sensitive data traffic. An example method includes identifying a request to deliver QoS-sensitive services to a User Equipment (UE) over at least one delivery network. The at least one delivery network may include at least one reserved resource and at least one pooled resource. The QoS-sensitive services are determined to be delivered over the at least one pooled resource. In addition, delivery of the QoS-sensitive services is caused over the at least one pooled resource.

  • Patent number: 11343288
    Abstract: Telecommunications network components configured to manage call control of a communication session of user equipment are described herein. An anchoring network device may proxy signaling traffic for the communication session. The anchoring network device may determine a routing identifier based at least in part on which access network, or which type of access network, is carrying the communication session, and may transmit state information of the communication session to a call-control server in association with the routing identifier. The call-control server may provide control information of the communication session to the anchoring network device in response to the state information. The anchoring network device may modify the communication session, e.g., by adding or dropping one or more parties, in response to the control information. The routing identifier may be determined based at least in part on capabilities of a communication session indicated in a session-initiation message.

  • Patent number: 11196731
    Abstract: In some examples, an authentication node of a telecommunications network can receive an authentication request from a terminal, and an authentication-control message. The authentication node can skip an authentication operation with respect to the authentication request in response to the authentication-control message. In some examples, a relay node of the telecommunications network can detect an overload or service-interruption condition and determine, in response, the authentication-control message. The relay node can send the authentication-control message to the authentication node. In some examples, an authentication node can detect that its load level satisfies a predetermined criterion and, in response, skip an authentication operation and send a first message. Another authentication node can receive an indication of the first message and, in response, perform a second authentication operation.

  • Patent number: 11146595
    Abstract: A service-based architecture (SBA) IP Multimedia Network Subsystem (IMS) network exposes Network Functions (NFs) to nodes within a 5G core network (CN), nodes within the SBA IMS network, and/or nodes within another network. In contrast to the SBA IMS network, legacy IMS networks are non-SBA IMS stateful networks that may utilize the Session Initiation Protocol (SIP). Utilizing the SBA IMS network, a node in the 5G core network can communicate directly with any node in the SBA IMS network. The SBA IMS network is stateless and open as opposed to stateful and closed as in SIP based legacy IMS networks. In some configurations, the SBA IMS network utilizes a HyperText Transfer Protocol (HTTP). For instance, instead of using the application layer SIP protocol, techniques can include using HTTP. The SBA IMS may also connect to legacy SIP IMS networks.

  • Patent number: 10965719
    Abstract: In some implementations, a telecommunications network can include a core network device. The core network device can receive from a session-originating device an initiation request of a communication session, the initiation request including information of a destination and information of media capabilities. The core network device can determine network-location information of the destination, retrieve from a capability registry modification information corresponding to the network-location information, and modify the information of the media capabilities based at least in part on the modification information. The core network device can transmit the initiation request including the modified information of the media capabilities to another core network device corresponding to the network-location information.

  • Patent number: 10880674
    Abstract: Systems and methods provided herein are directed to a mechanism for determining current or currently known location of a user equipment (UE). Upon receiving a request regarding location information of the UE, a gateway mobile location center (GMLC) may send a SIP OPTIONS to an interrogating call session control function (I-CSCF). In response to receiving the SIP OPTIONS, the I-CSCF may perform a location information request (LIR) and a location information answer (LIA) with the HSS to locate a serving call session control function (S-CSCF) where the UE is registered. The S-CSCF may route the SIP OPTIONS to an application server (AS) to request the registered location information of the UE, and in response, the AS may send a 200 OK, as an acknowledgment, to the S-CSCF, that includes location information of the UE provided during registration of the UE.
