  • Publication number: 20130091289
    Abstract: Methods and apparatus for handling a communication session for an unregistered Internet Protocol Multimedia Subsystem (IMS) device are disclosed. An example method includes, in response to receiving an internet protocol multimedia subsystem session initiation message from a user endpoint, determining whether the user endpoint is registered; and, when the user endpoint is determined to be unregistered: determining whether the internet protocol multimedia subsystem session initiation message is directed to an exception endpoint by performing a lookup on a list; determining whether a profile for the unregistered user endpoint is available; when the profile for the user endpoint determined to be unregistered is unavailable, loading a default profile; and establishing an internet protocol multimedia subsystem session on behalf of the user endpoint determined to be unregistered when the internet protocol multimedia subsystem session initiation message is directed to the exception endpoint.

  • Publication number: 20130044644
    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: 8370502
    Abstract: A method and an apparatus for processing a session request in an Internet Protocol (IP) network are disclosed. For example, the method receives a session request, and queries an tElephone NUmbering Mapping (ENUM) server for a called party of the session request. The method determines if at least one Naming Authority Pointer (NAPTR) resource record associated with the called party is received from the ENUM server, and forwards the session request to a circuit switched network if the at least one NAPTR resource record is not received from the ENUM server. The method determines a Session Description Protocol (SDP) value of the session request if the at least one NAPTR resource record is received from the ENUM server, and processes the session request in accordance with the SDP value if the at least one NAPTR resource record is received from the ENUM server.

  • Publication number: 20120314700
    Abstract: Methods for Enhancing the Scalability of IMS in VoIP Service Deployment lower the number of messages transmitted between functions of an IMS network. The number of messages transmitted between functions of an IMS network are lowered by storing and utilizing predetermined configuration information pertaining to the calling and called parties including the media and codecs the parties support. The predetermined configuration information, which may be based on a prior peering business agreement, supports the implementation of a one round procedure for establishing an IMS communication session.

  • Publication number: 20120287086
    Abstract: The claimed subject matter relates to an architecture that can utilize photo-sensors embedded in a substantially transparent layer of a UI display for tracking objects that approach or hover over the UI display. The photo-sensors can be configured to detect light of certain wavelengths (e.g., visible light, infrared light) that are propagated toward the UI display, while ignoring light emanating from the UI display when displaying content. Accordingly, by examining various characteristics of the incoming light such as intensity, the architecture can identify a location of a shadow incident upon the display caused by an approaching or hovering selector object blocking portions of incoming light. Additionally or alternatively, the architecture can identify a location of higher intensity for light emanating from the selector object.
