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.
Claims20
A computer readable storage device comprising executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:
- receiving, from a gateway device, handoff data representing a handoff event that changes a communication path for a user equipment device to another communication path;
- determining a handoff issue associated with the handoff event for the user equipment based on the handoff data;
- generating a notification in response to the determining the handoff issue;
- and
- transmitting the notification to a mobility management entity device, wherein the notification causes the mobility management entity device to select a different communication path for the user equipment and wherein the different communication path differs from the other communication path.
A computer readable storage device comprising executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:
- receiving handoff data representing a handoff operation that reroutes a communication path for a user equipment to another communication path that differs from the communication path;
- identifying, based on the handoff data, a handoff issue associated with the handoff operation;
- in response to the identifying the handoff issue, generating a notification comprising an instruction for a mobility management entity device of a long term evolution network to select an alternative communication path for the user equipment, wherein the alternative communication path differs from the other communication path;
- and
- providing the notification to the mobility management entity device.
A computer readable storage device comprising executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:
- receiving, from a gateway device of a long term evolution communication network, handoff data representing a handoff transaction that switches a first communication path for a mobile device to a second communication path that differs from the first communication path;
- determining a handoff issue associated with the handoff transaction based on the handoff data;
- and
- determining an alternative communication path for the mobile device in response to the identifying the handoff issue, wherein the alternative communication path differs from the second communication path.
