Dynamic Buddy List Assignment for Service Differentiation

The patent implements dynamic buddy list size assignment that adapts to individual client capabilities and service plans. Instead of a fixed size based on minimum capabilities, the system dynamically determines appropriate buddy list sizes for each client based on their actual device capabilities and subscribed service level, enabling both service differentiation and full capability utilization.

The patent applies different buddy list sizes to different clients based on their individual capabilities and service plans. Each client receives a customized buddy list size appropriate to their device capabilities and subscription level, rather than a uniform fixed size, thereby enabling service differentiation while maximizing device capability utilization for each user.

The patent performs capability detection and service plan determination during the session establishment phase. The server detects client capabilities and determines the appropriate buddy list size before the actual communication begins, storing this information for use during the session. This preliminary action avoids the need for complex real-time calculations during active communication.

The patent introduces a capability detection mechanism and service plan determination process as intermediaries between the server and client. These intermediaries handle the complexity of capability assessment and service matching, allowing the main communication system to remain relatively simple while still achieving dynamic service customization.
