Abstract

Systems, apparatuses, methods, and computer programs that communicate with a User Equipment (UE) device that is simultaneously using a first wireless communication protocol and a second wireless communication protocol; determine the UE device is proximate to a neighbor cell; determine the neighbor cell is absent from a neighbor relations table; cause the UE device to cease simultaneously using the first wireless communication protocol and the second wireless communication protocol; cause the UE device to only use the first wireless communication protocol; receive information while the UE device is only using the first wireless communication protocol; and use the information to add the neighbor cell to the neighbor relations table.

Claims (42)

1 . A method, comprising:

communicating with a User Equipment (UE) device that is simultaneously using a first wireless communication protocol and a second wireless communication protocol;

determining the UE device is proximate to a neighbor cell;

determining the neighbor cell is absent from a neighbor relations table;

based at least on determining the neighbor cell is absent from the neighbor relations table, causing the UE device to cease simultaneously using the first wireless communication protocol and the second wireless communication protocol so as to use the first wireless communication protocol and not the second wireless communication protocol;

receiving information while the UE device is using the first wireless communication protocol and not the second wireless communication protocol; and

using the information to add the neighbor cell to the neighbor relations table.

2 . The method of claim 1 , further comprising, based at least on the neighbor cell being added to the neighbor relations table, causing the UE device to simultaneously use the first wireless communication protocol and the second wireless communication protocol after the neighbor cell is added to the neighbor relations table.

3 . The method of claim 1 , further comprising determining the UE device is incapable of decoding or reporting a network-entity-related identifier.

4 . The method of claim 3 , wherein determining the UE device is incapable of decoding or reporting the network-entity-related identifier comprises determining the UE device is incapable of decoding or reporting an E-UTRAN Cell Global Identifier (ECGI).

5 . The method of claim 3 , wherein determining the UE device is incapable of decoding or reporting the network-entity-related identifier comprises determining the UE device has transmitted a plurality of communications including a same Physical Cell Identifier (PCI) of the neighbor cell.

6 . The method of claim 1 , wherein communicating with the UE device that is simultaneously using the first wireless communication protocol and the second wireless communication protocol comprises communicating using Eutra New Radio Dual Connectivity (ENDC).

7 . The method of claim 1 , wherein the determining the neighbor cell is absent from a neighbor relations table comprises:

receiving a Physical Cell Identifier (PCI) of the neighbor cell; and

determining the PCI of the neighbor cell is absent from a database storing PCIs associated with neighbor cells previously added to the neighbor relations table.

8 . The method of claim 1 , wherein causing the UE device to cease simultaneously using the first wireless communication protocol and the second wireless communication protocol comprises causing the UE device to only use an LTE communication protocol.

9 . A method, comprising:

communicating with a User Equipment (UE) device that is using a first wireless communication protocol;

determining the UE device is proximate to a neighbor cell;

determining the neighbor cell is absent from a neighbor relations table;

based at least on determining the neighbor cell is absent from the neighbor relations table, causing the UE device to stop using the first wireless communication protocol, by releasing a connection with a cell using the first wireless communication protocol, and start using a second wireless communication protocol;

receiving information while the UE device is using the second wireless communication protocol and not the first wireless communication protocol; and

using the information to add the neighbor cell to the neighbor relations table.

10 . The method of claim 9 , further comprising, based at least on the neighbor cell being added to the neighbor relations table, causing the UE device to stop using the second communication protocol and begin using the first wireless communication protocol after the neighbor cell is added to the neighbor relations table.

11 . The method of claim 9 , further comprising determining the UE device is incapable of decoding or reporting a network-entity-related identifier.

12 . The method of claim 11 , wherein determining the UE device is incapable of decoding or reporting the network-entity-related identifier comprises determining the UE device is incapable of decoding or reporting an E-UTRAN Cell Global Identifier (ECGI).

13 . The method of claim 11 , wherein determining the UE device is incapable of decoding or reporting the network-entity-related identifier comprises determining the UE device has transmitted a plurality of communications including a same Physical Cell Identifier (PCI) of the neighbor cell.

14 . The method of claim 9 , wherein communicating with the UE device that is using the first wireless communication protocol comprises communicating with a 5G UE device.

15 . The method of claim 9 , wherein determining the neighbor cell is absent from a neighbor relations table comprises:

receiving a Physical Cell Identifier (PCI) of the neighbor cell;

determining the PCI of the neighbor cell is absent from a database storing PCIs associated with neighbor cells previously added to the neighbor relations table.

16 . The method of claim 9 , wherein the second wireless communication protocol is an LTE communication protocol.

17 . A non-transitory computer-readable medium for storing computer readable program code or instructions for carrying out operations, when executed by a processor, for adding a neighbor cell to a neighbor relations table, the operations comprising:

communicating with a User Equipment (UE) device that is simultaneously using a first wireless communication protocol and a second wireless communication protocol;

determining the UE device is proximate to a neighbor cell;

determining the neighbor cell is absent from a neighbor relations table;

based at least on determining the neighbor cell is absent from the neighbor relations table, causing the UE device to cease simultaneously using the first wireless communication protocol and the second wireless communication protocol so as to use the first wireless communication protocol and not the second wireless communication protocol;

receiving information while the UE device is using the first wireless communication protocol and not the second wireless communication protocol; and

using the information to add the neighbor cell to the neighbor relations table.

18 . The non-transitory computer-readable medium of claim 17 , wherein the operations further comprise, based at least on the neighbor cell being added to the neighbor relations table, causing the UE device to simultaneously use the first wireless communication protocol and the second wireless communication protocol after the neighbor cell is added to the neighbor relations table.

19 . The non-transitory computer-readable medium of claim 17 , wherein the operations further comprise determining the UE device is incapable of decoding or reporting a network-entity-related identifier.

20 . The non-transitory computer-readable medium of claim 19 , wherein the operation of determining the UE device is incapable of decoding or reporting the network-entity-related identifier comprises determining the UE device is incapable of decoding or reporting an E-UTRAN Cell Global Identifier (ECGI).
