  • Patent number: 9559895
    Abstract: A network may include a method that includes, for example, receiving a communication request responsive to a telephone number mapping query failure, where the communication request is initiated by an originating communication device requesting a communication session with a terminating communication device, foregoing initiating the communication session as a circuit-switched communication session responsive to determining that the originating communication device and the terminating communication device are enabled to use packet-switched communications, and instructing a second network node to initiate the communication session as a packet-switched communication session between the originating communication device and the terminating communication device responsive to the determination. Other embodiments are disclosed.

  • Patent number: 9521081
    Abstract: Systems and methods to select peered border elements for a communication session based on Quality-of-Service (QoS) are disclosed. An example method includes selecting a peered border element to handle a communication session based on a list of peered border elements (PBEs) and a composite QoS parameter of the communication session, the list of PBEs being prioritized based on respective statuses of PBEs in the list, the first composite QoS parameter being based on weighted QoS parameters of the communication session including a grade of service (GoS) parameter of the communication session and a preferred mode of communication for a VoIP device of a called party in the communication session, the GoS parameter including an attempted performance range and an expected performance range of the communication session; and controlling a second server to generate a QoS authorization token to reserve network resources associated with the selected PBE.

  • Publication number: 20160359643
    Abstract: A method and an apparatus for completing a circuit switched service call in an Internet Protocol network are disclosed. For example, the method receives a session request from a calling party to a called party, wherein the session request includes a service tag. The method determines a value of the service tag in the session request, and queries an tElephone NUmbering Mapping (ENUM) server for one or more Naming Authority Pointer (NAPTR) resource records associated with the called party. The method selects one of the one or more NAPTR resource records in accordance with the service tag, if the one or more NAPTR resource records associated with the called party are returned, and processes the session request using the one of the one or more NAPTR resource records that is selected.

  • Patent number: 9509730
    Abstract: A method, apparatus and computer-readable medium for identifying a subscriber home domain in a communication network are described. A national subscriber profile is partitioned into regions and a NAPTR resource record is modified to identify in which region a particular subscriber is located. In response to a calling party requesting that a connection to a called party be established, a database is queried to provide a modified NAPTR record which identifies the region in which the called party is located. A connection can then be established without polling each region.

  • Patent number: 9420339
    Abstract: A method of determining demand for multimedia content in a multimedia provider network includes receiving a content demand statistics (CDS) request from a client application where the request identifies a subscriber set. Responsive to the CDS request, selected CDS data is retrieved from a CDS subsystem. The CDS data is indicative of demand for multimedia content among subscribers in the subscriber set. The retrieved CDS data is delivered to the client application. The selected data may be selected from past data, present data, and future data. The CDS request indicates a set of buddy subscribers and the messaging server retrieves CDS data associated with the buddy subscribers. A security subsystem may be accessed and to determine, prior to retrieving CDS data for a particular buddy subscriber, whether the particular buddy subscriber has authorized the requesting subscriber.

  • Patent number: 9398163
    Abstract: Internet protocol (IP) based calls from a first terminal in an IP based communications system are routed to a second terminal in another communications system. In response to a call setup request at a common communications core that is common to both the IP based communications system and the other communications system, a query is transmitted to a private telephone number mapping database that contains routing information for terminals in both the IP based communications system and the other communications system requesting routing information for the second terminal. Routing information for the call setup request is received from the private telephone number mapping database for routing the call.
