Activity-based uplink load estimation is considered for WCDMA. By taking the user activity explicitly into account, the method is suitable for a scenario where services with very different activity levels use the same RAB. Scenarios with different mixes of email and MMS (multimedia messaging service) traffic are considered. Simulations indicate that the method provides good accuracy in situations where methods without activity estimation may overestimate the uplink load with about 3 dB.
