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.

Method and system for managing destination addresses

There is described an interconnect hub for routing an Instant Message (IM) or related communication between a sending IM device in a first IM community and a recipient IM device in one of a plurality of potential second IM communities. The interconnect hub comprises a router for determining the destination of IM communications and routing the IM communications to the intended recipient, a search function for finding the service provider providing IM services to the user identifier, and a cache comprising a plurality of records associating user identifiers with corresponding service providers (mobile or Internet). When the IM communication is received by the interconnect hub, the router examines the recipient user identifier, accesses the cache keying on the recipient user identifier, retrieves the service provider associated with the recipient user identifier, and forwards the IM communication to the associated service provider for delivery to the intended recipient. If there is no record in the cache for the user identifier, the searcher initiates a search to identify the service provider and to update the cache if the service provider is found.

Method and system for instant messaging traffic routing

A network node provides presence updates to mobile users. The node reduces the amount of network traffic by eliminating the need for explicit messaging used to inform a user of presence updates. Additionally, the node reduces network traffic by consolidating presence updates, and sending the user only changed portions of the presence information.
