Serivice Type Indication in Association

This document discusses the optimization of access point (AP) parameters based on different service types associated with Station (STA) devices. It highlights the importance of adjusting the Delivery Traffic Indication Message (DTIM) interval and Max Idle Period according to the specific requirements of service types. Assigning suitable Active Identifiers (AIDs) helps in enhancing power saving for sensors and improving Time Interval Management (TIM) compression. The paper presents an approach for indicating service type during the association process and suggests using a bitmap for supported service types.

  1. Serivice Type Indication in Association Authors: Date: 2012-05-xx Wu Tianyu, Huawei

  2. Authors: Wu Tianyu, Huawei

  3. Different Service type has different requirements • AP can optimize the system parameters based on the service type Motivation Service Type Parameters Wu Tianyu, Huawei

  4. AP can: • Optimize the DTIM interval for STAs with different service type • Assign a longer DTIM interval for sensors can enhance the power save performance • Optimize the Max Idle Period for STAs with different service type • Sensor STAs may need a longer Max Idle Period • Assign appropriate AID for STAs with different service type • If AIDs for sensor STAs with low duty circle are assigned contiguously, there is higher chance for the TIM to have long contiguous 0s. • If AIDs for sensor STAs with same periodic duty circle are assigned contiguously, there is higher chance for the TIM to have long contiguous 1s. • This may help TIM compression. Parameter Optimization based on Service Type Wu Tianyu, Huawei

  5. STA provide service type information to the AP during association Add the service type field in Association request frame as shown below: Service Type indication during Association Wu Tianyu, Huawei

  6. An example of the service type element can be: • In the service Type byte, we can use a bitmap for the supported service types: Example of Service Type Element 1 1 1 Wu Tianyu, Huawei

  7. Do you support indicating service type during association? • Y/N/A: Straw Poll Wu Tianyu, Huawei
