US Patent 10574707 Reducing latency associated with communications

Described are techniques for establishing communications sessions between devices. A command from a sender device to initiate a communications session with a recipient device may include information indicative of a recipient user profile. Correspondence between recipient information and sender contact data may be used to determine the recipient user profile. Prior to providing a communication request to the recipient device, recipient contact data may be determined using the recipient user profile. Correspondence between the sender user profile and the recipient contact data may be used to determine sender information indicative of the sender. This information may be provided to the recipient device in advance of the communication request to enable more rapid acceptance of the communication request and eliminate the delay that would be incurred if the recipient device determined the sender information responsive to the communication request.
