Abstract: Systems and methods are described for avoiding packet loss during a handover. A handover request may be received at a control element of a first communication network. It may be determined that the handover request comprises a first type of handover request. A gateway node of the first communication network may be instructed to buffer packets for the wireless device based on the determination that the handover request comprises a first type of handover request. And the gateway node may be instructed to stop buffering the packets for the wireless device based on an execution of the requested handover.

Abstract: In systems and methods of detecting a wireless device utilizing unauthorized tethering, it is determined that a number of wireless devices in active communication with the access node meets a connections criteria, and that an access node loading meets a loading criteria. Packets received at the access node from the wireless devices are inspected to identify at least one short-lived data flow and a source wireless device of the at least one short-lived data flow. It is determined for the source wireless device a number of short-lived data flows during an observation time period, and the source wireless device is identified as performing unauthorized tethering when the number of short-lived data flows during the first time period meets a data flow threshold.

Abstract: A first throughput is determined of a first data flow at a gateway from a first access node and a second throughput is determined of second data flow at an inspection node from the gateway. A third throughput is determined comprising one or more third data flows from the gateway to a second access node based on a difference between the first throughput and the second throughput. At least one of the third data flows of the third throughput is identified, and when the third throughput meets a throughput threshold the identified third data flow is adjusted.

Abstract: An access node load distribution of a first radio access technology at a first time is received from a plurality of access nodes, the first time comprising a first deployment time of a second radio access technology to at least one of the plurality of access nodes. A baseline access node load distribution of the first radio access technology at a time before deployment of the second radio access technology to any of the plurality of access nodes is determined. A cross-correlation is calculated of the access node load distribution and the baseline access node load distribution. When a difference between the cross-correlation and the baseline access node load distribution is greater than or equal to a difference threshold, an access node load distribution of the second radio access technology is determined based on a combination of the access node load distribution of the first and second radio access technologies.

Abstract: When a first loading of a first access node is determined to meet a loading criteria, a handover criteria is decreased for a second access node comprising a coverage area at least a portion of which is within a coverage area of the first access node. A handover is performed of at least one of a plurality of wireless devices from the first access node to the second access node when a signal level of the second access node received at the at least one of the plurality of wireless devices meets the decreased handover criteria. Changes are determined in the first loading and in a throughput provided to the at least one of the wireless devices, and the handover criteria for the second access node is adjusted based on the changes in the first loading and the throughput provided to the at least one wireless device.

Abstract: An application requirement of an application running on a wireless device in communication with a first access node, a traffic class indicator associated with the wireless device, and a wireless communication link load between the wireless device and the first access node are determined. A probability of performing a first handover of the wireless device to a second access node and a second handover of the wireless device from the second access node to the first access node within a predetermined period of time is also determined. Based on the application requirement, the traffic class indicator, the wireless communication link load, and the determined probability, a context maintenance time is calculated, and a timer is started using the context maintenance time when the first handover is performed, and communication session information related to the communication between the wireless device and the first access node is maintained until the timer expires.

Abstract: At least one retransmission request is received from each of a plurality of wireless devices receiving a multicast broadcast, and a number of retransmission requests received from each of the plurality of wireless devices is determined. A first group of wireless devices is selected from among the plurality of wireless devices, and a delay time is determined for each wireless device in the first group based on the respective number of retransmission requests from each wireless device. When a data packet is not received at the one or more wireless devices of the first group, a timer is started at each of the wireless devices of the first group using the respective delay times. When the shortest delay time expires, another retransmission request is received from the wireless device comprising the shortest delay time of the one or more wireless devices.
