Multi-criteria handover in sdn-based multi-rat networks

A system comprising

• one or more processors and
• at least one memory storing processor-executable instructions that, when executed by any of the one or more processors, causes the one or more processors to perform operations comprising:
• generating a decision matrix, wherein (i) the decision matrix comprises a plurality of candidate network connection nodes and a plurality of network quality measurements corresponding to the plurality of candidate network connection nodes, (ii) the plurality of network quality measurements comprises received signal strength indicator (RSSI) and link delay, and (iii) the plurality of candidate network connection nodes correspond to a plurality of wireless access points or base stations that are within a range of a user equipment (UE);
• determining a plurality of criterion weights based on a plurality of entropy values corresponding to a plurality of criteria;
• generating, using the plurality of network quality measurements, a plurality of rankings for the plurality of candidate network connection nodes based on the plurality of criteria and the plurality of criterion weights;
• assigning, based on the plurality of rankings for the plurality of candidate network connection nodes, a highest-ranking candidate network connection node from the plurality of candidate network connection nodes as a target node and a second-ranking candidate network connection node from the plurality of candidate network connection nodes as a stand-in node;
• responsive to determining (i) the target node comprises a base station and (ii) a stand-in node RSSI value of the stand-in node is greater than (a) a target node RSSI value of the target node and (b) a threshold value, assigning the stand-in node as the target node;
• and
• initiating a radio link transfer or handover of the UE to the target node.

One or more non-transitory computer-readable storage media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• generating a decision matrix, wherein (i) the decision matrix comprises a plurality of candidate network connection nodes and a plurality of network quality measurements corresponding to the plurality of candidate network connection nodes, (ii) the plurality of network quality measurements comprises received signal strength indicator (RSSI) and link delay, and (iii) the plurality of candidate network connection nodes correspond to a plurality of wireless access points or base stations that are within a range of a user equipment (UE);
• determining a plurality of criterion weights based on a plurality of entropy values corresponding to a plurality of criteria;
• generating, using the plurality of network quality measurements, a plurality of rankings for the plurality of candidate network connection nodes based on the plurality of criteria and the plurality of criterion weights;
• assigning, based on the plurality of rankings for the plurality of candidate network connection nodes, a highest-ranking candidate network connection node from the plurality of candidate network connection nodes as a target node and a second-ranking candidate network connection node from the plurality of candidate network connection nodes as a stand-in node;
• responsive to determining (i) the target node comprises a base station and (ii) a stand-in node RSSI value of the stand-in node is greater than (a) a target node RSSI value of the target node and (b) a threshold value, assigning the stand-in node as the target node;
• and
• initiating a radio link transfer or handover of the UE to the target node.
