Claim of US Patent No. 10,405,164

1. A method for transmitting a message to a wireless device in a mesh network,the wireless device comprising a set of at least two distinct logical entities, the wireless device being arranged for receiving a message during discontinuous reception opportunities,
the method comprising, prior to transmission of the message, the steps of
(a) selecting a transmission mode from a set of transmission modes comprising a first transmission mode and a second transmission mode, where,
in the first transmission mode, the reception opportunities for the message are limited to the reception opportunities that are associated with a single selected logical entity of the set of at least two logical entities, and
in the second transmission mode, the reception opportunities for the message correspond to combined reception opportunities associated with at least two logical entities of the set of at least two logical entities; and
(b) causing the transmission of the message during one of the reception opportunities corresponding to the selected transmission mode; and
wherein steps (a) and (b) are carried out at a proxy node transmitting the message to a wireless device,
wherein the step (a) of selecting a transmission mode is based on a detected value of an indicator in a received control message indicative of the selected transmission mode,
wherein the step (b) of causing the transmission of the message includes substeps (b1) generating a message to be sent to the wireless device from the control message, and
(b2) transmitting the message to the wireless device based on the detected transmission mode,
where, in the first transmission mode, the reception opportunities for the message are limited to the reception opportunities associated with a single selected logical entity of the set of at least two logical entities, and
in the second transmission mode, the reception opportunities for the message correspond to combined reception opportunities associated with at least two logical entities.
