摘要:
A system that incorporates teachings of the present disclosure may include, for example, an edge device having a controller to receive a Session Initiation Protocol (SIP) message from a user endpoint device (UE) requesting communication services, forward the SIP message to a network element of a Server Office, receive from the network element a first error message indicating communication services at the Server Office are unavailable, replace the first error message with a second error message, the second error message indicating a temporary unavailability of communication services, and transmit the second error message to the UE. Additional embodiments are disclosed.

A system that incorporates teachings of the present disclosure may include, for example, a user endpoint device having a controller to submit a query to a Domain Name System (DNS) for information associated with a Fully Qualified Domain Name (FQDN) assigned to at least one of a Local Access Transport Area (LATA) or rate center of the user endpoint device, and receive from the DNS one or more descriptors of one or more session border controllers, wherein the one or more descriptors are associated with the FQDN of the user endpoint device. Additional embodiments are disclosed.
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 method and system for growing a next generation network (NGN) using a modular design are disclosed. For example, the method defines a growth core module to support a specific number of subscribers, wherein the growth core module is assigned a module identifier (ID). The method upgrades existing network entities that will be impacted by an installation of the growth core module in the existing IMS network, and installs the growth core module in the IMS network.
摘要:
A method and apparatus for providing a repeat calling service feature in a communication network are disclosed. For example, the method captures call session information between a calling endpoint and a called endpoint of a failed call due to an unavailability of required network resource. The method then receives a repeat calling service request from the calling endpoint, and processes the repeat calling service request to reestablish a call between the calling endpoint and the called endpoint.
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:
A system may include, for example, an Interrogating Call Session Control Function (I-CSCF) device having a processor adapted to receive a request from a Serving CSCF (S-CSCF) device communicatively coupled to a first communication device to establish communications with a second communication device responsive to the first communication device initiating a call directed to the second communication device, and to identify a primary S-CSCF device to which the second communication device is registered. The processor can also be adapted to detect a communication fault when attempting to communicate with the primary S-CSCF device, and to identify a secondary S-CSCF device that provides backup communication services to the second communication device responsive to detecting the communication fault. Other embodiments are disclosed.

摘要:
A method and apparatus for managing an overload condition in a network are disclosed. For example, the method monitors the network for a traffic overload condition, and determines whether a more severe traffic overload condition or a less severe traffic overload condition is detected by using a network monitor and controller. The method then selects using a network monitor and controller agent in response to a command from the network monitor and controller, a different bandwidth preservation scheme if the more severe traffic overload condition or the less severe traffic overload condition is detected, wherein the different bandwidth preservation scheme is based on a selection of a codec type and is applied to a portion of the traffic.
摘要:
A system that incorporates teachings of the present disclosure may include, for example, a Telephone Number Mapping system operating in a first IP Multimedia Subsystem (IMS) communication system having a controller adapted to receive first contact information of a communication device registered through a terminating Serving Call Session Control Function (S-CSCF) operating in a second IMS communication system and second contact information of at least one among an Interrogating CSCF (I-CSCF) of the second IMS communication system and the terminating S-CSCF. Additional embodiments are disclosed.
