Approaches for managing machine-to-machine (M2M) wireless devices are disclosed. M2M devices may be managed using broadcast messages wirelessly transmitted from a server. M2M wireless devices may be configured to utilize service classes in order to implement network access policy control. Features include per-message or per-group security; randomized delays for acknowledgements and/or network access, optionally per group or network access rule; sequence numbers and/or retransmissions for QoS; pre-defined pathname shortcuts; network access rules based on time, congestion and network events; estimates of congestion at various nodes; spreading and/or maximum wait times; default or universal service classes; application data streams mapped to service classes; and offline triggering. |
