Abstract:
Methods and apparatus to manage Internet Protocol (IP) Multimedia Subsystem (IMS) network capacity are disclosed. An example method comprises identifying a terminating voice over Internet protocol (VoIP) call server associated with a called device, and returning a call rejection indicator when the terminating VoIP call server is in a first condition, the call rejection indicator returned without a call initiation request message sent to the terminating VoIP call server.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, receiving a request for a voice call at a mobile switching center server, transmitting a mapping query from the mobile switching center server to a database in response to the request for the voice call, route the request from the mobile switching center server to an internet protocol multimedia subsystem for facilitating establishing the voice call when the mapping query is successful in obtaining an internet protocol address for establishing the voice call with a recipient communication device, and routing the request from the mobile switching center server to a second server for facilitating establishing the voice call without routing the request to the internet protocol multimedia subsystem when the mapping query is not successful in obtaining the internet protocol address. Other embodiments are disclosed.
Abstract:
Devices, systems and methods are disclosed for selecting and sending one of a plurality of responses to a call on a communications device. A user may select a default response or a custom response. When the user receives a call to a communications device, a set of responses is displayed on the communications device to facilitate selection by the user. A response includes a message and a call processing command. A message is in the form of an audio clip, text message, webpage, picture, video, etc. A call processing command, such as “accept call”; “reject call with voicemail”; “reject call without voicemail”; “place caller on hold”; “forward call to 555-555-5555”; “I will call you back”; etc. is performed along with the message. This plurality of responses can be organized by the user in groups associated with classes of callers, such as friends, family, co-workers, etc. In this manner, the responses available to the user when a call is received changes depending on the caller.
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. The method queries an tElephone NUmbering Mapping (ENUM) server for a called party of the session request, and determines if at least one Naming Authority Pointer (NAPTR) resource record associated with the called party is received from the ENUM server. The method determines if a Session Initiation Protocol Universal Resource Identifier (SIP URI) is returned, if the at least one NAPTR resource record associated with the called party is received, and processing the session request using the SIP URI, if the SIP URI is returned. The method determines if the processing of the session request using the SIP URI resulted in a successful call completion and processes the session request using a telephone URI, if the processing of the session request using the SIP URI resulted in an unsuccessful call completion.
Abstract:
Methods and apparatus to select a peered voice over Internet protocol (VoIP) border element are disclosed. An example method comprises receiving a session initiation protocol (SIP) message that includes an identifier representative of a location of a voice over Internet protocol (VoIP) access border element, querying a telephone number mapping (ENUM) database to identify two or more peered VoIP border elements, and selecting a one of the two or more peered VoIP border elements based on the identifier.
Abstract:
Methods and apparatus to route a communication session in an Internet Protocol (IP) Multimedia Subsystem (IMS) network are disclosed. An example method comprises determining at a tElephone NUMber mapping (ENUM) query server if a called destination associated with an ENUM query request message is subject to re-direction, and determining at the ENUM server a final destination for the called destination when the destination is subject to redirection, the final destination being different from the called destination.
Abstract:
A method that incorporates teachings of the subject disclosure may include, for example, transmitting a first query to a domain naming server responsive to receiving a session initiation protocol message comprising a fully qualified domain name. The first query can include one of an internet protocol version 4 address query or an internet protocol version 6 address query associated with the fully qualified domain name. The method can include receiving at least one answer from the domain naming server. The at least one answer can include at least one of an internet protocol version 4 address having no errors, a second internet protocol version 6 address having no errors, or both. The method can also include transmitting a message to a communication device. The message can include information associated with the at least one answer.
Abstract:
A session request from a first subscriber is received at a first network component of a packet-based network. The session request comprises a request to establish a communications session between the first subscriber and a second subscriber. In the event the session request originated in a trusted network, the first network component permits access to unique resource identifier (URI) information associated with the second subscriber for use in establishing the communications session via the packet-based network. In the event the session request did not originate in a trusted network and in response to determining a security configuration associated with the second subscriber allows the first subscriber to access the URI information under the circumstances, the first network component permits access to the URI information for use in establishing the communications session via the packet-based network. In response to determining the security configuration prohibits access to the URI information by the first subscriber under the circumstances, the first network component forwards the session request to a second network component so as to establish the communications session via a public switched telephone network.
Abstract:
A method and apparatus for managing ENUM records is disclosed. An apparatus that incorporates teachings of the present disclosure may include, for example, a broker having a detection element that detects a Resource Record (RR) submission made by an IP Multimedia Subsystem (IMS), and a comparison element that retrieves from an object-oriented data storage element a zone associated with the RR, identifies a Domain Name Server (DNS) responsible for processing said zone, compares the zone with a volatile memory of the DNS, and updates the volatile memory according to one or more differences detected. Additional embodiments are disclosed.
Abstract:
A method and an apparatus for providing privacy for a telephone number in a network are disclosed. The method receives a call associated with a disposable telephone number, and determines a call processing feature for the disposable phone number in accordance with a filtering function. The method then processes the call in accordance with the call processing feature for the disposable phone number.
