Maritime machine-to-machine (M2M) application priority management
First Claim
1. A network node for use in a telecommunications network, the network node capable of communicating with a radio access node located onboard a vehicle, wherein the radio access node communicates via a satellite link in order to communicate application traffic on behalf of machine-to-machine (M2M) devices onboard the vehicle, the network node comprising:
- a database that stores a plurality of recovery modes, wherein each recovery mode indicates one or more types of application traffic that the M2M devices are or are not allowed to transmit when operating according to that recovery mode; and
a control unit configured to;
detect a loss of communication across, or congestion on, the satellite link;
select one of the plurality of recovery modes in response to detecting the loss of communication across, or congestion on, the satellite link; and
,request the radio access node to broadcast the selected recovery mode over a 3GPP-based broadcast channel in order to instruct the M2M devices to transmit only application traffic allowed in accordance with the selected recovery mode.

Abstract
A network node communicates with a radio access node that communicates application traffic on behalf of machine-to-machine (M2M) devices via a satellite link. The network node comprises a database and a control unit. The database stores a plurality of recovery modes. Each recovery mode indicates one or more types of application traffic that M2M devices are or are not allowed to transmit when operating according to that recovery mode. The control unit detects a loss of communication across, or congestion on, the satellite link, selects one of the recovery modes, and requests the radio access node to broadcast the selected recovery mode over a 3GPP-based broadcast channel in order to instruct the M2M devices to transmit only application traffic allowed in accordance with the selected recovery mode.
