Various embodiments disclosed herein provide for a caller identification (ID) method and system that can provide caller ID information to display on devices other than the wireless equipment device that is receiving the phone call. This can include televisions and other streaming devices associated with the user receiving the phone call. The mobile wireless network associated with the user's wireless user equipment can determine whether the user has an additional device on which caller ID is to be displayed, and then identify a media server associated with the additional device. Once identified, the mobile wireless network can provide the media server with the caller ID information so that it can be displayed on the television or other streaming device.

Caller identification for a destination wireless user equipment

Various embodiments describe methods, systems, and devices for establishing a packet cable multi-media (PCMM) session. Exemplary implementations may receiving, a call initiation request message; determine whether a negative PCMM response associated with the call initiation request message is received; determine whether to ignore the negative PCMM response based on a call preferences parameter associated with the first UE in response to determining that the negative PCMM response is received; and establish a call associated with the call initiation request message in response to determining to ignore the negative PCMM response based on the call preferences parameter associated with the first UE.

Continued PCMM session establishment

A SMS message is conditionally additionally directed toward an STB, located at the customer premises, to which the target phone number of the SMS message corresponds, and is displayed on a device, e.g., a TV, coupled to the STB, in addition to being directed to the phone corresponding to the target phone number. A new STB SMS server: i) determines whether an incoming SIP message including a SMS message is to be sent toward a STB for SMS display on a display device coupled to the STB, or is to be dropped, e.g., based on a SMS_DISPLAY_STB flag value in a subscriber profile corresponding to the target phone number, ii) determines, for a SIP message including a SMS message, a particular video endpoint, and iii) sends a SIP message including a SMS message to a determined video endpoint for SMS message delivery to a STB interfacing with the video endpoint.

Methods and apparatus for communicating and displaying short message service (SMS) messages

Disclosed herein are apparatus and methods for reducing latency in core network processing in the telecommunications networks. A method includes receiving, by a network function (NF) at registration time with a network function repository function (NRF), resource metrics and a network address for each NF registered with the NRF, invoking, by the NF, one or more network addresses to request updated resource metrics from an associated NF, starting, by the NF, a response timer for each invoked network address, stopping, by the NF, the response timer for each invoked network address upon receipt of an updated resource metrics from the associated NF, determining, by the NF, a round-trip time for each associated NF having a start time and a stop time, and determining, by the NF, a ranking for each NF based on at least one of the round-trip time and the updated resource metrics.

Apparatus and method for network function signaling latency reduction

Various embodiments include network computing devices and methods for computing resource management. Various embodiments include network computing devices and methods for managing IP Multimedia Subsystem (IMS) registration of a user equipment (UE). A processor of a network computing device may send to a home subscriber server (HSS) a user authorization request in response to receiving a registration request from the UE. The processor may receive from the HSS a user authorization answer comprising subscriber location information associated with the UE. The processor may send a registration request to register the UE with a serving CSCF (S-CSCF) based on the subscriber location information and S-CSCF location information.

Managing IP multimedia subsystem (IMS) registration

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.

Apparatus and methods for device location determination

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.

Enhanced domain name system (DNS) server

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.

Apparatus and method for P-CSCF failure detection and processing

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 sendsa 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.

Enhanced domain name system response caching

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.

Systems and methods for updating a resource address

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.

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.
