  • Patent number: 11283749
    Abstract: A method and system for controlling message transmission for a communication group are disclosed. While a message-on-hold mode remains activated for a first communication group at a first client device: the device, in response to detecting a change in the usage of the first client device: in accordance with a determination that communication suspension criteria are met with respect to the first communication group, prevents transmission of communications in the first communication group to the first client device; and in accordance with a determination that communication resumption criteria are met with respect to the first communication group, temporarily enables transmission of communications in the first communication group to the first client device without deactivating the message-on-hold mode for the first communication group.
