摘要:
Described herein are systems, devices, and methods that improve network communication on a high-latency network by using a low-latency network to manage return-link bandwidth. Embodiments of the systems described herein include a user terminal that is communicatively coupled to a high-latency network and a low-latency network. The user terminal is configured to communicate with a gateway routing device over the low-latency network. The user terminal requests return-link bandwidth and the gateway routing device provides a transmission schedule to the user terminal over the low-latency network. The user terminal can be configured to transmit a message over the high-latency network using the scheduled return-link bandwidth.

The following description describes a solution for increasing downstream throughput of TCP data packet involving a flow control mechanism in access networks. The solution is based on the use of the RBSes knowledge from the radio network to ensure optimal TCP throughput performance by influencing TCP flow control mechanism. By adding a prescheduling functionality in the RBS the solution will create fair and optimized mobile network performance for TCP flows.

LWA (LTE/WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant user perceived throughput (UPT) improvement. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can dispatch the PDU either delivered over LTE link or WLAN link. The UPT improvement depends on how the eNB dispatches the PDU over LTE link or WLAN link. In one novel aspect, the eNB can acquire channel information, load information, and throughput estimation regarding with WLAN link and LTE link. As a result, the eNB can optimize UPT and LWA PDU dispatching algorithm.

The present disclosure generally relates to the field of resource reservation. More specifically, the present disclosure relates to a technique of reserving communication resources in a wireless communication network. A method embodiment comprises: receiving (S402), by a node of the plurality of nodes, a resource reservation message including first reservation information indicating one or more communication resources for at least one link of the wireless communication network; modifying (S404), by the node, the received resource reservation message by including second reservation information indicating one or more communication resources for a link of the node in the received resource reservation message; and transmitting (S406), by the node, the modified resource reservation message to one or more neighbor nodes of the node.

A technique may include determining a congestion level for a cell, receiving, from a user device, data associated with a user device flow from the user device, determining one or more flow events for the user device flow, sending, from the base station, information, including the congestion level and the one or more flow events, to a quality of experience manager to allow the quality of experience manager to determine one or more updated quality of service profiles for the user device, receiving, by the base station from the quality of experience manager, an updated quality of service profile for the user device flow, sending, by the base station to the user device based upon the updated quality of service profile for the user device flow, instructions to the user device to cause the user device to adjust an uplink data rate of the user device flow.

The invention relates to network nodes and methods therein for network congestion mitigation. A method in a first network node comprises entering a congestion mitigation mode, CMM; receiving a service request originating from a wireless device; and, in response to said service request, when the service request fulfills a criterion: redirecting the wireless device to a predefined e MBMS session, thereby enabling an informative alternative to rejection of the service request.
