Mobility and zone management in zone-based federated learning

An apparatus for managing model updates, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor being configured:
• to receive, at a zone management device of a plurality of zone management devices, a global model from a first network device associated with the global model, each of the plurality of zone management devices associated with one of a plurality of zones and a corresponding zone model of a plurality of zone models;
• to transmit, from the zone management device, the global model to mobile devices in a first zone of the plurality of zones, the first zone being associated with a first zone model;
• to receive, at the zone management device, weights associated with the global model from each mobile device in the first zone;
• to update, at the zone management device, the first zone model based on the received weights and a zone membership of each of the mobile devices, the zone membership of each mobile device being determined based at least in part on a zone mobility of each of the mobile devices, respectively, between the first zone and other zones of the plurality of zones;
• and
• to transmit, from the zone management device, the updated first zone model to each mobile device in the first zone.

An apparatus for managing model updates, comprising:

• means for receiving, at a zone management device of a plurality of zone management devices, a global model from a first network device associated with the global model, each of the plurality of zone management devices associated with one of a plurality of zones and a corresponding zone model of a plurality of zone models;
• means for transmitting, from the zone management device, the global model to mobile devices in a first zone of the plurality of zones, the first zone being associated with a first zone model;
• means for receiving, at the zone management device, weights associated with the global model from each mobile device in the first zone;
• means for updating, at the zone management device, the first zone model based on the received weights and a zone membership of each of the mobile devices, the zone membership of each mobile device being determined based at least in part on a zone mobility of each of the mobile devices, respectively, between the first zone and other zones of the plurality of zones;
• and
• means for transmitting, from the zone management device, the updated first zone model to each mobile device in the first zone.

A non-transitory computer readable medium having encoded thereon program code for managing model updates, the program code being executed by a processor and comprising:

• program code to receive, at a zone management device of a plurality of zone management devices, a global model from a first network device associated with the global model, each of the plurality of zone management devices associated with one of a plurality of zones and a corresponding zone model of a plurality of zone models;
• program code to transmit, from the zone management device, the global model to mobile devices in a first zone of the plurality of zones, the first zone being associated with a first zone model;
• program code to receive, at the zone management device, weights associated with the global model from each mobile device in the first zone;
• program code to update, at the zone management device, the first zone model based on the received weights and a zone membership of each of the mobile devices, the zone membership of each mobile device being determined based at least in part on a zone mobility of each of the mobile devices, respectively, between the first zone and other zones of the plurality of zones;
• and
• program code to transmit, from the zone management device, the updated first zone model to each mobile device in the first zone.
