A telecommunication network limits bandwidth usage for devices associated with lower service priority levels, thus conserving physical resources for use by devices with higher service priority levels. Low priority devices can include mobile virtual network operator (MVNO) devices, roaming devices, Internet of Things (IoT) devices, and/or the like. The telecommunication network enforces the limited bandwidth usage if a low priority device is capable of using channel subdivisions (e.g., bandwidth parts (BWPs)), and this device capability is communicated during a UE capability exchange that occurs during a registration process. Core network functions provide a policy that specifies a limited channel bandwidth for a capable low-priority device to a network node of the telecommunication network to which the wireless device is communicably coupled. The network node configures the wireless device to use the limited channel bandwidth according to the policy.

Configuring limited channel bandwidth usage for low-priority network devices

Systems, methods, and process nodes for managing bandwidth in a telecommunications network include or implement operations of receiving a connection request from a wireless communication device capable of communication in a first band having a first frequency and in a second band having a second frequency; receiving a capability report from the wireless communication device; and in response to a determination that the capability report meets a criteria, assigning the wireless communication device to communicate in the second band.

System and method for bandwidth management based on UE capability

In User Equipment (UE) at various geographic locations, circuitry exchanges TCP packets with radios, and the radios wirelessly exchange the TCP packets with wireless communication nodes. The circuitry determines TCP retransmission rates for the radios at the geographic locations. The circuitry estimates TCP retransmission rates for the radios at a new geographic location based on the TCP retransmission rates for the radios at the past geographic locations. The circuitry selects one of the radios based on the estimated TCP retransmission rates at the new geographic location. At the new geographic location, the circuitry exchanges new TCP packets with the selected one of the radios, and the selected one of the radios wirelessly exchanges the new TCP packets with one of the wireless communication nodes.

Transmission control protocol (TCP) control over radio communications

A mobile User Equipment (UE) uses Transmission Control Protocol (TCP) to deliver mobile data services over different radios. The mobile UE qualifies the individual radios that have adequate signal strength at a geographic location. The mobile UE estimates TCP retransmission rates at the location for the qualified radios. The mobile UE identifies individual qualified radios that have adequate TCP retransmission rate estimates. The mobile UE selects one of the identified radios that has the lowest power usage. The mobile UE exchanges TCP packets over the selected radio which includes participating in TCP retransmissions at the location. The selected radio wirelessly exchanges the TCP packets with a wireless access node. The mobile UE stores resulting TCP retransmission data for the selected radio in association with the location for future TCP retransmission rate estimates.

A method and system for blindly triggering handover based on past failures to trigger handover of beamforming-served devices. A computing system identifies a geolocation area where wireless communication devices (WCDs) that are served with beamforming by a first access node tend to experience radio link failure after having reported to the first access node being within threshold weak coverage of the first access node and threshold strong coverage of a second access node. And, based on the identifying, the computing system then blindly triggers handover of a given WCD from the first access node to the second access node in response to determining that the given WCD is served with beamforming by the first access node while positioned in the identified geolocation area.

Blind handover with adaptive learning based on past failures to trigger handover of beamforming-served devices

Systems, methods, and processing nodes for limiting connection requests from wireless devices instruct certain wireless devices to stop sending connection requests or to turn off a radio of the wireless devices, based on a determination that the wireless device is not authorized to access the wireless network. Thus, resource consumption associated with signaling overhead is minimized.

Limiting connection requests from wireless devices

A wireless user device exchanges data with wireless networks over wireless channels and measures communication metrics for the wireless channels. The wireless user device transfers the communication metrics to other wireless user devices and receives other communication metrics from the other wireless user devices. The wireless user device processes the communication metrics to select an optimal set of communication channels. The wireless user device disables the unselected ones of the wireless channels. The wireless user device exchanges wireless data with the wireless networks over the optimal set of wireless communication channels.

Wireless user device communications over optimal wireless communication channels

A method and system to help control transmission over an air interface from a base station to a served WCD. When the base station has a threshold small quantity of data to transmit over the air to a WCD, the base station will schedule the transmission to occur in a downlink PRB of a special subframe, rather than in a PRB of a regular downlink subframe. As the downlink PRB of the special subframe likely has fewer useable resource elements than the PRB of the regular downlink subframe, this process could help to minimize waste of air interface resources resulting from not making use of resource elements in an allocated PRB.
