Redirecting handovers in LTE networks
First Claim
Patent Images
1. A system, comprising:
- a processor; and
a memory, that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;
receiving, from a serving gateway device of a long term evolution network, handover data representing a set of handover procedures that switch a first communication path for a user equipment to a second communication path;
identifying a handover condition associated with a handover procedure of the set of handover procedures based on the handover data;
creating a notification in response to the identifying the handover condition; and
instructing a mobility management entity device of the long term evolution network to select an alternative communication path for the user equipment in response to the notification, wherein the alternative communication path differs from the second communication path.

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.

11. A method, comprising:
-
receiving, by a serving gateway device comprising a processor, handover data representing a set of handover operations that reroute a first communication path for a user equipment to a second communication path; identifying, by the serving gateway device, a handover issue associated with a handover operation of the set of handover operations based on the handover data; and instructing, by the serving gateway device, a mobility management entity device of a long term evolution network to select an alternative communication path for the user equipment in response to the identifying the handover issue, wherein the alternative communication path differs from the second communication path. - View Dependent Claims (12, 13, 14, 15)

16. A computer readable storage device comprising executable instructions that, in response to execution, cause a mobility management entity device comprising a processor to perform operations, comprising:
-
receiving, from a serving gateway device of a long term evolution communication network, handover data representing a set of handover transactions that switch a first communication path for a mobile device to a second communication path; identifying a handover issue associated with a handover transaction of the set of handover transactions based on the handover data; and determining an alternative communication path for the mobile device in response to the identifying the handover issue, wherein the alternative communication path differs from the second communication path. - View Dependent Claims (17, 18, 19, 20)
