Method and system for managing destination addresses

摘要

A method for downloading destination addresses associated with a given client device from a server to the client device is disclosed. The method comprises the steps of determining a resource limitation of the client device, sorting the addresses, and transmitting a subset of the sorted addresses from the server to the device, wherein the transmitted sorted address subset is determined by the resource limitation.;There is also provided a system and server for supporting Instant Messaging (IM). The system comprises a telecommunications network interconnecting a plurality of IM clients and an IM server, the plurality of IM clients configured to exchange instant messages with one another via the telecommunications network and the IM server, each of the IM clients having an associated IM address, the IM server comprising a memory for storing a plurality of IM addresses, a set of the IM addresses corresponding to each of the IM clients and wherein a given set comprises at least one IM address other than an IM address of the IM client to which the given set corresponds, wherein on occurrence of a triggering event associated with a particular IM client the IM server selects a subset of the IM addresses from the set of addresses corresponding to the particular IM client based on a resource limitation of the particular IM client and transmits the selected IM address subset to the particular IM client.
