Wireless local area network (WLAN) traffic load measurement provisioning to wireless cellular networks
Generally, this disclosure provides devices, systems and methods for provisioning of wireless local area network (WLAN) traffic load measurements to third generation partnership project 3GPP wireless cellular networks. A WLAN element manager (EM) may include a polling module to poll a WLAN access point (AP), the polling to request traffic load data from the WLAN AP; a timer module to trigger the polling module to poll at periodic intervals; a logging module to receive and log the requested traffic load data; and an integration reference point (IRP) agent including a reporting module to generate a traffic load report for transmission to a network manager (NM), the traffic load report based on the logged traffic load data.
1. A wireless local area network (WLAN) element manager (EM) for managing a WLAN domain comprising a group of WLAN access points (APs), comprising one or more processors configured to:
poll a WLAN AP, the polling to request traffic load data from the WLAN AP;
trigger the polling of the WLAN AP at a periodic interval for polling;
receive the traffic load data through a type 1 interface and log the requested traffic load data;
map the logged traffic load data from a WLAN standard interface format to a third generation partnership project (3GPP) standard interface format to generate 3GPP format traffic load data; and
generate a traffic load report based on the 3GPP format traffic load data and transmit the traffic load report using a type 2 interface to a network manager (NM).
2. The WLAN EM of claim 1 , wherein the periodic interval for polling the WLAN AP is configured based on traffic load requirements of a base station external to the WLAN domain.
3. The WLAN EM of claim 1 , wherein the traffic load data comprises a channel utilization indicator.
4. The WLAN EM of claim 3 , wherein the one or more processors are is configured to receive a management information base (MIB) message that includes a dot11ChannelUtilization data element corresponding to the channel utilization indicator.
5. The WLAN EM of claim 1 , wherein the traffic load data comprises an available admission capacity indicator.
6. The WLAN EM of claim 5 , wherein the one or more processors are is configured to receive a management information base (MIB) message that includes a dot11AvailableAdmissionCapacity data element corresponding to the available admission capacity indicator.
7. The WLAN EM of claim 1 , wherein the one or more processors are configured to provide the traffic load report to the NM in response to a polling request from the NM.
8. The WLAN EM of claim 1 , wherein the reporting module one or more processors are configured to incorporate the traffic load data in the 3GPP standard interface format in one or more data elements associated with a management information base (MIB) message transmitted to the NM via a standardized interface.
9. A method for traffic load measurement, comprising:
polling, through a type 1 interface, a wireless local area network (WLAN) access point (AP) in a WLAN domain to request traffic load data from the WLAN AP, the polling triggered at a periodic interval for polling;
receiving the requested traffic load data, wherein the traffic load data comprises a management information base (MIB) message that includes data elements associated with traffic load in the WLAN;
logging the received traffic load data in a log file;
mapping the logged traffic load data from a WLAN standard interface format to a third generation partnership project (3GPP) standard interface format to generate 3GPP format traffic load data;
generating a traffic load report based on the 3GPP format traffic load data; and
transmitting the traffic load report to a network manager (NM) using a type 2 interface.
10. The method of claim 9 , wherein the periodic interval for polling the WLAN AP is configured based on traffic load requirements of base station external to the WLAN domain.
11. The method of claim 9 , wherein the traffic load data comprises a channel utilization indicator.
12. The method of claim 11 , wherein the traffic load data comprises a management information base (MIB) message that includes a dot11ChannelUtilization data element corresponding to the channel utilization indicator.
13. The method of claim 9 , wherein the traffic load data comprises an available admission capacity indicator.
14. The method of claim 13 , wherein the traffic load data comprises a management information base (MIB) message that includes a dot11AvailableAdmissionCapacity data element corresponding to the available admission capacity indicator.
15. The method of claim 9 , further comprising transmitting the traffic load report to the NM in response to a polling request from the NM.
