Abstract
A base station provides, a first number of probe packets to an access point for transmission to a user equipment over an access network path. The base station receives information indicating a bandwidth of the access network path estimated by the user equipment. The base station determines which of the base station or the access point to use for communication with the user equipment based on the bandwidth. The user equipment receives a second number of packets over an air interface and determines inter-arrival packet delays for the second number of probe packets. The user equipment estimates the bandwidth of the air interface based on the inter-arrival packet delays, the first number, and a time interval for transmission of the first number of probe packets. The user equipment transmits information indicating the bandwidth.
