System and method for detecting mutually supported capabilities between mobile devices

摘要

A system and method for detecting mutually supported capabilities between two or more mobile devices is described. In some cases, the system transmits a message to a called device requesting information about the device. In some cases, the transmitted message is answered by a user of the device. In some cases, the transmitted message is automatically received and answered by the called device. In some cases, the system presents information about a service supported by a called party during a call placed to the party.

1. A method of identifying a service supported by a second mobile device, the method comprising:
at a first mobile device associated with a user, receiving an indication of a voice call placed to a called number for the second mobile device; transmitting via the first mobile device a first message to the second mobile device,
wherein the first message is configured to request whether one or more first services that are supported by the first mobile device are supported by the second mobile device; receiving at the first mobile device a second message from the second mobile device that indicates, as one or more second services, a subset of the first services that are supported by the second mobile device; determining that a counter is below a threshold value; requesting a selection from the user of a service of the one or more second services; after determining that the counter is below the threshold value, receiving a selected service from the user; and in response to receiving the selected service from the user, initiating a communications channel using the selected service and switching communications between the first mobile device and the second mobile device to the selected service using the communications channel instead of the voice call; wherein the counter specifies a number of times the user has responded to the requesting of the selection in relation to the called number.
