  • Apparatus and method for reducing LTE-to-1XRTT border cell cross-paging in circuit switched fall back call delivery
    Patent number: 8165608
    Abstract: A technique is provided to leverage the border cell paging capability to eliminate paging waste during LTE-to-1xRTT cross-RAT paging for CSFB call delivery. A method comprises receiving a call for the user equipment at the first switching element, sending a page request to the user equipment by the first switching element via the LTE elements, sending a page invoke message by the first switching element to a plurality of switching elements on a border between the first area and the second area, the page invoke message having an indicator field indicating a status of listen only, receiving a page response from the user equipment at the second switching element, recognizing the page response by the second switching element based on the page invoke message, and, completing the call to the user equipment.

  • Forced bearer routing for packet-mode interception
    Patent number: 7436835
    Abstract: A method of intercepting call content in a packet-based Internet Protocol (IP) network. The method includes targeting bearer packets containing the call content via a Softswitch controlling the redirection of the targeted bearer packets through a specified Intercept Router using alias IP addresses for the targeted bearer packets.
