  • Patent number: 11368424
    Abstract: Systems, methods, and devices for resolving a network address include a Domain Name System (DNS) server configured to receive a request for a resource from a client device, determine a source IP address of the client device based on the information included in the received request, and determine whether the source IP address is included in a source client list. The server may identify a view associated with the source client list, and associate the client with the identified view, in response to determining that the source IP address is included in the source client list. The server may associate the client with a default view in response to determining that the source IP address is not included in the source client list.

  • Patent number: 11252200
    Abstract: Described herein are apparatus and methods for detecting and handling Proxy-Call Session Control Function (P-CSCF) failures. A method may include sending, by a serving-CSCF (S-CSCF), a message to the P-CSCF to check operability. The S-CSCF may mark in a list that the P-CSCF is unavailable if a negative response or no response is received from the P-CSCF and may set a timer to recheck availability of the unavailable P-CSCF. A message is sent by the S-CSCF to a device management system to force a user device to stop using the unavailable P-CSCF and register with a different P-CSCF. The S-CSCF may recheck availability of the unavailable P-CSCF upon expiration of the timer and may remove the unavailable P-CSCF from the list when a positive response is received from the unavailable P-CSCF.

  • Publication number: 20210368292
    Abstract: Apparatus and methods for provision of location-based services to wireless device users. In one embodiment, the apparatus and methods support location-based services requiring indoors or underground positioning (or other applications which cannot be served by GPS/A-GPS or GLONASS), such as via Wi-Fi Location devices with fine timing measurement (FTM) capability. A cable, terrestrial or satellite network operator can obtain location data on e.g., an LTE-enabled UE with SIM capability located within a served premises or venue, via an HTTP/S GET protocol, and forward the location data. In one variant, a managed 3GPP IP Multimedia System (IMS) infrastructure is used in conjunction with UE-specific identifiers under control of a controller entity (e.g., ePDG) in communication with the IMS infrastructure and one or more FTM-enabled Wi-Fi APs within the premises or venue for supporting VoWi-Fi 911 or 411 packet calls made via the IMS.

  • Patent number: 11122138
    Abstract: Methods and systems for enhanced domain name system (DNS) response caching are described. An enhanced DNS response caching method includes receiving a connection request for a fully qualified domain name (FQDN). A DNS client checks a local cache for a cached resolved domain name corresponding to the FQDN and sends 3300 a query to obtain or refresh the cached resolved domain name if a Time to Live parameter is expired or about to expire. In response to receiving a negative response or no response for the query, the DNS client determines whether an enhanced DNS response caching parameter is enabled. If the enhanced DNS response caching parameter is enabled, the DNS client sends an expired cached resolved domain name to process the connection request.

  • Patent number: 11050707
    Abstract: Various embodiments include computing devices and methods for updating a resource address. A processor of a computing device may receive a request for a resource address from a second computing device. The processor may send to the second computing device the resource address and a time-to-live for the resource address. The processor may determine that the resource address has changed within the time-to-live. The processor may send the changed resource address to the second computing device.

  • Patent number: 10972426
    Abstract: Systems, methods, and devices for resolving a network address include a Domain Name System (DNS) server configured to receive a request for a resource from a client device, determine a source IP address of the client device, and determine whether the source IP address is included in a source client list. In response to determining that the source IP address is not included in the source client list, the DNS server may determine whether a default view datastore includes a record for requested resource. If the default view datastore does not include a record for requested resource, the DNS server may determine whether the requested resource is included in the view datastore. If the requested resource is included in the view datastore, the DNS server may generate and send to the client device a response message that includes a SIPNOTDEFINED indication.

  • Patent number: 10798134
    Abstract: Systems, methods, and devices of the various embodiments disclosed herein may enable automatic retry of Internet Protocol (IP) Multimedia Subsystem (IMS) Based Session Initiation Protocol (SIP) Call Setup. Various embodiments may enable a server in an IMS based telecommunication network, such as a proxy-call session control function (P-CSCF) server, interrogating/serving-call session control function (I/S-CSCF) server, telephony application server (TAS), etc., to reattempt SIP call setup. In various embodiments, in response to receiving a SIP error response including a retry-after header, the server may wait a period of time before sending a new SIP invite message.
