Abstract

A wireless communication network serves User Equipment (UE) based on co-location and Received Signal Strength (RSS). A serving wireless access node selects itself for an uplink and downlink when no candidate wireless access nodes are co-located with the serving node. The serving node selects a candidate node for the uplink and downlink when the candidate node is co-located with the serving node and has an RSS level that exceeds a first threshold. The serving node selects itself for the uplink and selects a candidate node for the downlink when the candidate node is co-located with the serving node and has an RSS between the first threshold and a second threshold. The UE may trigger access node selection by entering idle mode. The serving node may condition the selection of a candidate node on whether the candidate node supports a wireless network slice for the UE.

Dependent claims

A method of operating a wireless communication network to serve a User Equipment (UE) based on co-location and Received Signal Strength (RSS) levels, the method comprising:

a serving wireless access node selecting the serving wireless access node for an uplink and a downlink for the UE when candidate wireless access nodes are not co-located with the serving wireless access node, and in response, wirelessly exchanging user data with the UE over the uplink and the downlink;
the serving wireless access node selecting one of the candidate wireless access nodes for the uplink and the downlink for the UE when the one of the candidate wireless access nodes is co-located with the serving wireless access node and has a highest one of the RSS levels that exceeds a first threshold;
the one of the candidate wireless access nodes wirelessly exchanging the user data with the UE over the uplink and the downlink when the one of the candidate wireless access nodes is co-located with the serving wireless access node and has the highest one of the RSS levels that exceeds the first threshold;
the serving wireless access node selecting the serving wireless access node for the uplink for the UE and selecting another one of the candidate wireless access nodes for the downlink for the UE when the other one of the candidate wireless access nodes has the highest one of the RSS levels that falls below the first threshold and that exceeds a second threshold, and wirelessly receiving an uplink portion of the user data from the UE over the uplink;
and
the other one of the candidate wireless access nodes wirelessly transferring a downlink portion of the user data to the UE over the downlink when the other one of the candidate wireless access nodes is co-located with the serving wireless access node and has the highest one of the RSS levels that falls below the first threshold and exceeds the second threshold.

and
the other one of the candidate wireless access nodes configured to wirelessly transfer a downlink portion of the user data to the UE over the downlink when the other one of the candidate wireless access nodes is co-located with the serving wireless access node and has the highest one of the RSS levels that falls below the first threshold and exceeds the second threshold.
