A wireless communication network manages a wireless access node. The wireless access node wirelessly exchanges user data with wireless User Equipment (UEs) and exchanges the user data with one or more network elements. The wireless access node generates status indicators that characterize wireless access node operation during the user data exchanges. An Element Management System (EMS) determines EMS load based on EMS operation and transfers load data that indicates the EMS load for delivery to the wireless access node. The wireless access node receives the load data transferred by the EMS. The wireless access node identifies individual priorities for individual ones of the status indicators. The wireless access node determines individual reporting times for the individual ones of the status indicators based on the load data and the individual priorities. The wireless access node transfers the individual ones of the status indicators to the EMS per the individual reporting times.

Wireless access network element status reporting

A wireless access network element wirelessly exchanges user data with wireless User Equipment (UEs) and exchanges the user data with other network elements. The wireless access network element generates status indicators that characterize the wireless access network element during the user data exchanges. The wireless access network element identifies priorities for the status indicators. The wireless access network element receives load data from a network element manager. The wireless access network element processes the load data and the priorities to determine individual reporting times for the status indicators. The wireless access network element transfers the individual status indicators to the network element management system per the individual reporting times.

In a communication system comprising a base station having a set of carrier frequencies, ranging from a lowest to a highest carrier frequency, for serving user equipment devices (UEs), the base station may schedule a first transmission of first bearer traffic to be on a first carrier frequency of the set based at least in part on a correlation between (i) the first bearer traffic being of a first type of bearer traffic and (ii) where the first carrier frequency falls within the range of carrier frequencies. The base station may also schedule a second transmission of second bearer traffic to be on a second, different carrier frequency of the set based at least in part on a correlation between (i) the second bearer traffic being of a second, different type of bearer traffic and (ii) where the second carrier frequency falls within the range of carrier frequencies.

Method and system for selecting a carrier on which to schedule communications of a type of bearer traffic

A wireless User Equipment (UE) attaches to a Fifth Generation New Radio (5GNR) gNodeB in a wireless communication network. The wireless communication network receives a Guaranteed Bit Rate (GBR) request for the UE. In the wireless communication network, a Policy Control Function (PCF) efficiently invokes an Access and Mobility Management Function (AMF) and a Session Management Function (SMF) to effectively serve the GBR request. The AMF signals the UE and the 5GNR gNodeB to initiate the GBR service over the Long Term Evolution eNodeB. The SMF signals a data gateway to initiate the GBR service with the LTE eNodeB. The UE attaches to the LTE eNodeB. The LTE eNodeB and the data gateway deliver the requested GBR service to the UE.

Wireless guaranteed bit rate (GBR) data service

Systems, methods, and computer-readable media, for reducing transitions between active and idle states are provided. In some embodiments, transition data indicating transitions between an active state and an idle state associated with a mobile device is received. Thereafter, an idle state pattern that indicates a pattern of an idle state associated with the mobile device is identified. Based on the idle state pattern, an inactivity timer update corresponding with the idle state pattern is provided to at least one communication tower. The inactivity timer update provides a time duration or time duration adjustment to be applied by the at least one communication tower for use in detecting a transition from an active state to an idle state.

Reducing transitions between idle and active states

A wireless relay attaches to a wireless base station and broadcasts a wireless hop count. Another wireless relay receives the wireless hop count and attaches to the wireless relay. The other wireless relay increments the wireless hop count and broadcasts the incremented wireless hop count. The wireless relays receive attachment requests from User Equipment (UEs) responsive to their wireless hop counts. The wireless relays exchange user data with the UEs after the attachments.

Data communication network to provide hop count data for user equipment selection of a wireless relay

An interference level is determined in an uplink portion of a wireless communication link between a wireless device and an access node. A traffic class of data is identified in a first portion of the uplink portion, and resource blocks in a second portion of the uplink portion are selected based on the determined interference level and the identified traffic class. The wireless device is sent an allocation of the selected resource blocks in the second portion of the uplink portion, and control channel information is received from the wireless device in the uplink portion in the selected resource blocks.

Allocating wireless communication link resources in a control channel

Disclosed is a method and system for selecting a target base station for handover of a wireless communication device, where the selecting is based at least in part on a consideration of the target base station's typical control-plane signaling latency in a core network, and particularly based on a comparison of control-plane signaling duration of multiple candidate target base stations. For instance, where all of the base stations are configured to engage in a particular control-plane signaling transaction from time to time, at issue could be which of the candidate target base stations typically engages in that control-plane signaling transaction the quickest.

Control of handover based on past duration of control-plane signaling

A computer-implemented method, system, and computer-readable storage media for scheduling physical resource blocks are provided. Base stations, of a communication radio access network, may be configured with schedulers that assign one or more physical resource blocks to a communication channel of a wireless device based on distance or power. The physical resource blocks allow the wireless device to communicate with the base station. Some resource blocks may be monitored across multiple sites to determine whether an aggregate power for the resource blocks exceeds a threshold. When the aggregate power threshold is surpassed, the schedulers may limit or prevent use of the identified resource blocks.

Avoiding satellite interference to long term evolution systems

Disclosed are systems and methods for providing system-acquisition parameters on standardized frequencies. One embodiment takes the form of a method for assisting mobile devices with system acquisition. The method includes, in each of two or more wireless coverage areas, broadcasting from a radio access network (RAN) on each of one or more predefined frequencies one or more sets of one or more system-acquisition parameters. The method also includes configuring one or more mobile devices with logic executable for, in response to detecting a triggering event, retrieving at least one of the sets of system-acquisition parameters on at least one of the predefined frequencies, and then using at least one retrieved set of system-acquisition parameters to attempt to acquire system connectivity.

A data communication network to provide hop count data for User Equipment (UE) selection of a wireless relay. The data communication network comprises a macro base station and a plurality of wireless relays that serve UEs. The wireless relays receive a hop count, and in response, increment their individual hop count and wirelessly broadcast individual relay Long Term Evolution (LTE) System Information Blocks (SIBs) indicating their individual hop counts. The wireless relays receive wireless UE attachments responsive to the relay LTE SIB broadcasts of their individual hop counts.

A method and system for controlling handover of a WCD based on the WCD's operating temperature. In an example implementation, a determination is made that the WCD's operating temperature is threshold high, and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as to another carrier frequency or to another base station coverage area. Further, in another example implementation, a determination is made that the WCD's operating temperature is threshold low (e.g., is not threshold high), and that determination is used as a basis to trigger handover of the WCD to another coverage system, such as back to the WCD's initially serving coverage system.

Method and system for use of operating temperature as basis to control handover

An RF fingerprint of the environment of a base station antenna will be regularly monitored, such as by regularly evaluating various RF metrics of uplink reflections of downlink transmission from the antenna. Through regular monitoring of the RF fingerprint, a baseline RF fingerprint could be established. And through continued monitoring of the RF fingerprint, an unexpected change in the RF fingerprint could then be detected, as an indication that the antenna's RF beam direction may have changed. In response to detecting the unexpected change in the antenna's RF fingerprint, the antenna's RF beam direction could then be newly determined, and the antenna's configuration record could be updated to indicate the newly determined RF beam direction.

Method and system for updating configuration record of base station antenna

A method of operating User Equipment (UE) in a data communication network that comprises a macro base station and a plurality of wireless relays that serve the UE to select a communication session type based on a hop count. The method comprises UEs that attach to one of a plurality of wireless relays and determine a hop count for the attached wireless relay. The UEs select a session type based on the hop count and initiate a communication session of the selected session type with the attached wireless relay.

Selecting a communication session type based on a hop count

Disclosed is a method and system to help manage handover of a UE based on data buffering. In accordance with the disclosure, when a base station receives data destined for a UE, the base station may record the received data into a data buffer for temporary storage and retrieve the data at some later time to transmit the data to the UE. The base station may then determine, based at least in part on an amount of elapsed time from recording the data to retrieving the data, whether to invoke handover of the UE from being served by the base station to being served by a different, neighboring base station.
