摘要:
A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium including computer instructions for receiving an emergency request to assist a subscriber, retrieving presence information of each of a plurality of parties that serve as emergency contacts for the subscriber, selecting a communication identifier of at least one of the plurality of parties according to the presence information, and notifying the at least one party of the emergency request. Additional embodiments are disclosed.
摘要:
A method of monitoring network performance is disclosed and includes receiving a session initiation protocol (SIP) response message from one of a plurality of serving-call session control function (S-CSCF) systems at a centralized error monitoring server of an Internet Protocol (IP) Multimedia Subsystem (IMS). The SIP response message includes at least one error code that matches an error monitoring initial filter criterion included in a subscriber profile. The method also includes sending an alert message to a fault management system of the IMS when at least one threshold related to SIP error codes is met or exceeded based on the at least one error code.
摘要:
A communication system includes an application server that includes logic to recognize that preference data in each of a plurality of data record entries of a subscriber record has a common value. Each data record entry includes a Uniform Resource Identifier (URI), and the subscriber record is stored in a telephone number mapping (ENUM) server. The application server also includes logic to issue a command to initiate contact concurrently with devices identified by URIs in the subscriber record via an Internet Protocol Multimedia Subsystem (IMS).

摘要:
A method and an apparatus for providing mobility for a Voice over Internet Protocol Service (VoIP) provided on packet networks are disclosed. For example, the method receives a register request from a user endpoint device and retrieves an Access Point-address parameter from a contact header in the register request. The method then determines a physical location of an access point device in accordance with the Access Point-address parameter and updates location information for the user endpoint device in accordance with the physical location of the access point device.
摘要:
A system for deploying Voice over Internet Protocol (VoIP) services is provided. A system that incorporates teachings of the present disclosure may include, for example, a Call Session Control Function (CSCF) having a controller element to receive a Session Initiation Protocol (SIP)message from an originating communication device requesting communications with a terminating communication device, and establish an Internet Protocol (IP) connection between the originating communication device and an advertisement media system to present at the originating communication device an advertisement message that replaces a ringback tone associated with the terminating communication device. Additional embodiments are disclosed.
摘要:
Network-based methods and systems transfer caller ID information from a telephony network to an IPTV network. Embodiments integrate service provisioning, subscriber account and policy information between telephony services and IP-based television services. Voice call signaling may be intercepted to retrieve caller ID, caller name information, and other call management information, at the call server in the network to deliver an appropriate notification message to the IP-based TV network at its notification server, which in turn sends a message notification to the called party's TV screen. Call log information may also be retrieved and displayed. SIP call forking and IP multimedia subsystem approaches are described.
摘要:
A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to adjust a call processing logic for Session Initiated Protocol to Integrated Services Digital Network User Part (ISUP) calls based at least in part on interworking profiles assigned to ISUP trunk groups supporting the calls. Additional embodiments are disclosed.
摘要:
A mechanism controls global synchronization, or registration floods, that may result when a large number of endpoints in a Voice over Internet Protocol (VoIP) network such as an Internet Protocol Multimedia Subsystem (IMS) come online simultaneously after a catastrophic failure. The mechanism allows the Domain Name System (DNS) infrastructure to efficiently control the overload condition by registering user end points with backup border elements, and by staggering and by randomizing the time-to-live (TTL) parameter in registrations with backup border elements.
摘要:
A method includes receiving a message at a server. The message indicates that a network is unable to fulfill a request for media content for a user device. The method may also include sending, from the server to the user device, an offer to inform the user device when the network is able to fulfill the request.
