Abstract

A method includes receiving, from a radio access network (RAN) node within a wireless network, connection event information for one or more user devices and associated channel condition information; and determining a connection behavior status of a user device based on at least a portion of the connection event information and associated channel condition information and a connection behavior status model, wherein the connection behavior status model provides a mapping or association between connection event information and associated channel condition information for one or more user devices and a connection behavior status.

First claim

What is claimed is:

1. A method comprising:
receiving, from a radio access network (RAN) node within a wireless network, connection event information for a user device and associated channel condition information;
identifying a connection behavior status model that maps the connection event information and associated channel condition information to a connection behavior status;
determining, using the connection behavior status model, a connection behavior status for the user device based on the connection event information and associated channel condition information, the device connection behavior indicating a low-performing connection behavior status for the user device; and
sending a message to cause another network node, within the wireless network, to perform, based on the connection behavior status of the user device, a network corrective action with respect to the user device to improve a connection behavior of the user device, the network corrective action including updating a profile and/or registry to mark the user device as low performing.

2. The method of claim 1 , and further comprising:
sending a message to a network node indicating the connection behavior status of the user device.

3. The method of claim 1 , wherein the user device is part of a subset of user devices that have one or more common features or aspects that cause the user devices of the subset of user devices to exhibit a same or similar connection behavior, at least part of the time;
wherein the receiving comprises receiving, from a radio access network (RAN) node within a wireless network, connection event information for a plurality of user devices of the subset of user devices and associated channel condition information;
wherein the connection behavior status model comprises a connection behavior status model that provides a mapping or association between connection event information for at least one or more user devices of the subset of user devices and associated channel condition information and a connection behavior status.

4. The method of claim 3 , wherein one or more common features or aspects of the subset of user devices comprise one or more of:
a same user device brand or manufacturer;
a same user device model;
user devices that include a same semiconductor chip or chipset;
user devices that include a same version of a protocol entity;
user devices that include a same hardware module;
user devices that include a same software module;
user devices that include a same antenna system or antenna configuration.

5. The method of claim 1 , wherein the connection event information comprises at least one of:
a connection event, including one or more of:
a successful connection attempt to a cell by the user device;
the user device performing a random access procedure with a cell;
the user device successfully starting transmission to a cell for control signals or data; and
a cell providing the user device with configuration information to allow the user device to configure itself for communication with the cell; and

a loss of connection event, including one or more of:
an unsuccessful connection attempt to a cell by the user device;
the user device being unable to transmit or receive data or control signals to a cell;
at least a threshold number or threshold rate of data retransmission events with a cell; and
at least a threshold number or a threshold rate of decoding errors;

channel condition information within a threshold period of time before the connection event;
channel condition information at a time of the connection event;
channel condition information within a threshold period of time after the connection event; and
a channel quality information, a data error rate or block error rate, a channel state information (CSI), a reference signal received power (RSRP), a reference signal received quality (RSRQ), a signal to interference plus noise ratio (SINR), a random access (RACH) timing advance, a direction and/or angle of arrival of signals, beam information indication for transmit or receive beams, per antenna measurements for antenna strength and/or phase.

6. The method of claim 1 , wherein the network corrective action with respect to the user device to improve a connection behavior of the user device comprises at least one of:
adjusting a modulation and coding scheme (MCS) of the user device, adjusting transmission power of the user device for uplink transmissions, adjusting downlink transmission power for transmissions to the user device, adjusting a retransmission timing or strategy, adjusting signal threshold(s) for handover of the user device between cells, adjusting resource scheduling for the user device, adjusting a control channel element (CCE) selection for a physical downlink control channel (PDCC), adjusting beamforming or other MIMO transmission strategy, updating a subscription profile for the user device to indicate the connection behavior status of the user device, triggering or causing an update to a subscription plan or charging/billing for the user device or subscriber, triggering or causing a call trace to collect data for the subscriber or user device connection, determining or maintaining counts of the connection events or changes to the connection behavior status of the user device, causing or triggering a problem report or status report to be generated and/or transmitted to a hardware or software or device manufacturer.

7. The method of claim 1 , wherein the determining a connection behavior status model comprises determining an artificial intelligence (AI) model or a neural network model.

8. The method of claim 1 , further comprising training the connection model, wherein the training the connection behavior status model comprises performing at least one of:
training the connection behavior status model using supervised learning;
training the connection behavior status model using supervised learning; and
training the connection behavior status model using reinforcement learning.

9. The method of claim 1 , wherein the RAN node receives at least part of the connection event information and associated channel information from another RAN node.

10. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
receive, from a radio access network (RAN) node within a wireless network, connection event information for one or more user devices and associated channel condition information;
identify a connection behavior status model that maps the connection event information and associated channel condition information to a connection behavior status;
determine, using the connection behavior status model, a connection behavior status for a user device based on the connection event information and associated channel condition information, the device connection behavior indicating a low-performing connection behavior status for the user device; and
sending a message to cause another network node, within the wireless network, to perform, based on the connection behavior status of the user device, a network corrective action with respect to the user device to improve a connection behavior of the user device, the network corrective action including updating a profile and/or registry to mark the user device as low performing.
