Abstract:
Nowadays, the focus of network operation is no longer on the coverage and basic services but it is rather centered around the quality of experience that can be provided to the subscribers and on the capability of smoothly operating complex, interactive and increasingly data hungry applications on mobile platforms. Despite the increased system capacity, improved efficiency and sophisticated quality of service (QoS) architectures, the right level of quality of experience (QoE) requires application level differentiation. Using a single data bearer for each user equipment (UE), which is a common setup due to system and equipment limitation and the bearer centric QoS architectures, represents a barrier in providing true differentiation between simultaneously used applications. This paper discusses possible application level differentiation mechanisms either assuming a single data bearer per UE or utilizing the potential of secondary bearers to prioritize selected applications. The mechanisms were evaluated and compared by simulations focusing promoting web browsing over bulk data transfer in a High Speed Packet Access (HSPA) network. Results show that application differentiation mechanisms are able to significantly improve the quality of experience.
