Proactive caching of transient assistant action suggestions at a feature phone

A method performed by one or more remote servers in selective network communication with an assistant client application executed by one or more processors of a feature phone, the method comprising:

• generating a time-constrained transient assistant action suggestion for a future event having dynamic temporal features;
• determining, based on interfacing with one or more remote systems, at least one temporal window for the dynamic temporal features of the future event;
• generating rendering restriction metadata for the time-constrained transient assistant action suggestion based on the temporal window, the rendering restriction metadata constraining rendering of the time-constrained transient assistant action suggestion to the at least one temporal window;
• generating proactive cache refresh rate metadata for the time-constrained transient assistant action suggestion based on one or more characteristics of the future event, the proactive cache refresh rate metadata defining a duration during which the assistant client application is to refrain from interfacing with a remote system to prefetch updates for at least the time-constrained transient assistant action suggestion;
• receiving, from the assistant client application of the feature phone, a transient action suggestions prefetch request;
• and
• providing, in response to the transient action suggestions prefetch request, at least the time-constrained transient assistant action suggestion and the rendering restriction metadata;
• providing, in response to the transient action suggestions prefetch request or an additional asynchronous request from the assistant client application of the feature phone, the proactive cache refresh rate metadata for the time-constrained transient assistant action suggestion.

A method performed by one or more remote servers, the method comprising:

• generating transient assistant action suggestions;
• receiving, from corresponding assistant client applications of a plurality of feature phones in a geographic area, corresponding transient action suggestions prefetch requests;
• providing the transient action suggestions in response to each of the corresponding transient action suggestions prefetch requests;
• determining a change in load at one or more of the remote servers and/or a change in one or more network conditions in the geographic area;
• in response to determining the change in the load and/or the change in the one or more network conditions:
• generating updated proactive cache refresh rate metadata, the updated proactive cache refresh rate metadata defining a duration during which the corresponding assistant client applications are to refrain from interfacing with one or more of the remote servers to prefetch updated transient assistant action suggestions;
• and
• transmitting, to the corresponding assistant client applications and asynchronously with respect to any transient action suggestions prefetch requests, the updated proactive cache refresh rate metadata to the corresponding assistant client applications of the plurality of feature phones for supplanting any locally stored preexisting proactive cache refresh rate metadata.
