Traffic Coordination for Communication Sessions Involving Wireless Terminals and Server Devices

The invention concerns a communication synchronization device (16), method, computer program and computer program product for synchronizing communication (RQ, PRES) as well as to a method, wireless device (58), computer program and computer program product for handling such communication. The device (16) investigates (36) the communication patterns of communications between the wireless terminal (24) and server devices (18, 20, 22) communication sessions (CS1. CS2, CS3) between applications (A1, A2, A3) running in the wireless terminal and the server devices (18, 20, 22), determines a downlink coordination group, collects (38) server device transmissions (PRES) of the group made by the server devices through aligning them with each other in time and sends (40) the collected transmissions to the wireless terminal as an aggregated transmission via a common wireless link. The wireless device (58) receives (52) the aggregated transmission and distributes (54) data therein to the applications (A1, A2, A3).
