Abstract

Claims (31)

1. A method of operating a wireless local area network, the wireless local area network including a user device, a wireless access point and a wireless repeater, wherein the wireless repeater is configured to virtualise a Media Access Control, MAC, address of the user device when the user device is connected to the wireless repeater by changing the Organisationally Unique Identifier, OUI, of the MAC address, the method comprising the steps of:

obtaining data including a plurality of records, wherein each record of the plurality of records relates to the user device and includes a MAC address and a device label of the user device, wherein at least one record of the plurality of records includes a MAC address that has been virtualised by the wireless repeater;

processing each record of the plurality of records by:

determining that the MAC address of the processed record is a local MAC address, and, if so,

identifying another record of the plurality of records that is uniquely associated with the user device based on the MAC address of the processed record by

determining a Network Interface Controller, NIC, value of the MAC address of the processed record,

determining that the determined NIC value is uniquely associated with a device label in the plurality of records, and

identifying another record of the plurality of records having the associated device label, and

assigning a unique device identifier for uniquely identifying the user device to the processed record based on the MAC address of the identified other record of the plurality of records;

analysing the plurality of records having the unique device identifier; and

causing a reconfiguration in the wireless local area network based on the analysis.

2. A method as claimed in claim 1 , wherein each record of the plurality of records also includes a timestamp and the step of identifying another record of the plurality of records having the associated device label identifies a plurality of other records having the associated device label, and the method further comprises the step of:

identifying a record of the plurality of other records having the associated device label having the most recent timestamp.

3. A method as claimed in claim 1 , wherein, prior to the step of determining that the determined NIC value is uniquely associated with the device label in the plurality of records, the method further comprises the step of:

determining that a count of other records of the plurality of records having globally unique MAC addresses with the determined NIC value is zero.

4. A non-transitory computer readable carrier medium storing a computer program which, when executed by a computer, cause the computer to carry out the steps of claim 1 .

5. A data processing device for of operating a wireless local area network, the wireless local area network including a user device, a wireless access point and a wireless repeater, wherein the wireless repeater is configured to virtualise a Media Access Control, MAC, address of the user device when the user device is connected to the wireless repeater by changing the Organisationally Unique Identifier, OUI, of the MAC address, the data processing device comprising a processor and memory storing instructions which are executable by the processor such that the data processing device is at least configured to:

obtain data including a plurality of records, wherein each record of the plurality of records relates to the user device and includes a MAC address and a device label of the user device, wherein at least one record of the plurality of records includes a MAC address that has been virtualised by the wireless repeater;

process each record of the plurality of records by being configured to:

determine that the MAC address of the processed record is a local MAC address, and, if so,

identify another record of the plurality of records that is uniquely associated with the user device based on the MAC address of the processed record by

determine a Network Interface Controller, NIC, value of the MAC address of the processed record,

determine that the determined NIC value is uniquely associated with a device label in the plurality of records, and

identify another record of the plurality of records having the associated device label, and

assign a unique device identifier for uniquely identifying the user device to the processed record based on the MAC address of the identified other record of the plurality of records;

analyze the plurality of records having the unique device identifier; and

cause a reconfiguration in the wireless local area network based on the analysis.

6. The data processing device as in claim 5 , wherein each record of the plurality of records also includes a timestamp and the identification of another record of the plurality of records having the associated device label identifies a plurality of other records having the associated device label, and the data processing device is further configured to:

identify a record of the plurality of other records having the associated device label having the most recent timestamp.

7. The data processing device as in claim 5 , wherein the data processing device is further configured to, prior to the determination that the determined NIC value is uniquely associated with the device label in the plurality of records,

determine that a count of other records of the plurality of records having globally unique MAC addresses with the determined NIC value is zero.
