    Abstract: In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

  • Patent number: 8582566
    Abstract: Disclosed is a method and system for mutually exchanging capability information of UEs for communication between a Circuit-Switched (CS) and IMS services (CSI) UE, which can use a CS call for voice communication while using an IMS session for PS service, and an IMS UE which uses an IMS session for both voice communication and PS service. A MGCF performs interworking of capability information between a CS message and an IMS message so that the IMS UE can process UE capability information through an IMS session request/response. When a call request message containing no capability information is created from a UE not supporting capability exchange, a CSI AS transfers the call request message to a peer UE after inserting estimable capability information of the UE into the call request message, and stores capability information of the counterpart UE for the UE.

  • Patent number: 8582559
    Abstract: A mechanism for managing and enhancing communication streams in a VOIP service using SIP is discussed. SIP is used to manage and enhance a communication stream at a centralized switching element in the VoIP environment rather than at the communication stream endpoints. The communication stream set up by SIP is directed through a central switching element under administrative control rather than traveling directly between the stream endpoints. As a result, the media stream may be conditioned with treatments and may be provided with enhanced services at the central switching element without the specific treatments and services being supported at both stream endpoints. The use of the centralized switching element allows full administrative control of the VoIP environment.

  • Publication number: 20130294444
    Abstract: Method and apparatus for voice traffic management in a data network includes establishing a default maximum bandwidth setting at a LAN egress port when voice-type traffic is not present in a LAN portion of the data network, detecting voice-type traffic, reducing the bandwidth setting at the LAN egress port to effect a change in a rate of non voice type traffic and monitoring non voice type traffic and voice quality statistics to determine if the rate of non voice type traffic entering the data network has changed. Once the desired change has occurred, performing a linear increase of the bandwidth setting at the LAN egress port to a first value while monitoring voice quality statistics, determining if voice quality has degraded during increase of the bandwidth setting and repeating the last two steps if voice quality has not degraded.

  • Patent number: 8570764
    Abstract: The embodiments of the present invention disclose a backplane and backplane system. The backplane includes at least two service slots with the same function and an exchange slot. Among the pins of different service slots with the same function respectively connected to the exchange slot, at least two pins are arranged to resemble a stepped form. When arranged in this manner, the distribution and orientation of the connection lines connecting the pins of the service slots with the same function to the exchange slot may be adjusted, and wiring density within a single wiring layer may be increased, which therefore enables the connection lines between the service slots and the exchange slot to be staggered from each other in less wiring layers or even one wiring layer, and as a result, decreases the number of the wiring layers to be used, and reduces the costs of the backplane.

  • Patent number: 8570906
    Abstract: A method and apparatus for enabling a network provider to instantly assign a virtual number to a subscriber to use until their primary number is successfully ported to the VoIP network is disclosed. For example, a virtual number can be a phone number for callers outside a subscriber's local calling area to call the subscriber for the price of a local call if the subscriber chooses a virtual phone number in their local calling area. After the porting of the primary number is successful, the user can be reached by either having callers directly dial the primary number or the previously assigned virtual number. The subscriber can continue to use both phone numbers or choose to disconnect the virtual number and only use the successfully ported primary number.
