Optimizing data traffic and power consumption in mobile unified communication applications

A mobile server for optimizing data traffic between a mobile application and a unified communication network, the mobile server comprising:

• a memory for storing computer-executable instructions;
• a processor coupled to the memory, the processor configured to execute instructions to cause actions including:
• dynamically determine a timing of message exchanges between the mobile server and the mobile application based on an iterative adjustment of a delay value and a system timeout;
• cache presence data received from subscribers of the unified communication network;
• prioritize the cached presence data based on at least one from a set of:
• whether a subscriber associated with the mobile application is active,
• whether a portion of the cached presence data is of interest to the subscriber associated with the mobile application, and
• whether the cached presence data is associated with an available subscriber;
• and
• provide at least a portion of the cached presence data to the mobile application based on the prioritization.

A system for optimizing data traffic between a mobile application and a mobile server in a unified communication network, the system comprising:

• a mobile device for executing the mobile application and for communicating with the mobile server and other communication devices over a cellular network, wherein the mobile application is configured to:
• provide an iteratively adjusted delay value to the mobile server during an “always-on” connection to dynamically determine an optimum timing for exchange of messages between the mobile application and the mobile server;
• determine a list of contacts of interest through one of:
• subscriber selection and heuristic computation;
• and
• provide to the mobile server the list of contacts of interest and an activity status of the subscriber;
• and
• the mobile server configured to:
• cache presence data received from other subscribers of the unified communication network;
• determine a portion of the cached presence data based on the list of contacts of interest to the subscriber and an activity status of the contacts on the list;
• provide the portion of the cached presence data to the mobile application.
