  • Redirecting handovers in LTE networks
    Patent number: 9363714
    Abstract: An architecture that can redirect communications upon detection of a handover failure in a Long Term Evolution (LTE) network is described. The architecture can obtain information indicative of a handover failure that is available in a first portion of the LTE network (e.g., a serving gateway) that has no control over the communication path. The architecture can utilize the information to instruct a second portion of the LTE network (e.g., a mobility management entity), one that can control the communication path but conventionally has no access to the handover information, to reroute the communication path to avoid unresponsive or failing network entities.
    Type: Grant
    Filed: March 16, 2015
    Date of Patent: June 7, 2016
