Abstract
Systems and methods provide for bundling subscriptions associated with a Machine-to-Machine (M2M) device or M2M application into a single hypertext transport protocol (HTTP) session. A method includes subscribing, by a gateway (GW), to an M2M device on behalf of a plurality of subscribers using a single Hypertext Transport Protocol (HTTP) session.
Claims9
A method for handling subscriptions in a machine-to-machine system, the method comprising:
- receiving at a gateway a subscription request associated with both a machine to machine device and a machine to machine network server;
- determining that the received subscription request is directed to a second event associated with a resource with which a plurality of previous subscriptions have been registered for first events, the first and second events being different from each other;
- closing a session associated with the previous subscriptions with the resource;
- transmitting to the resource a new subscription determined in accordance with the previous subscriptions and the received subscription request, the new subscription associated with the first and second events;
- and
- updating a traffic table based on the closing of the session associated with the previous subscriptions and on the transmitting of the new subscription to the resource.

A gateway (GW) for communicating data in a
- Machine-to-Machine (M2M) network comprising:
- a communications interface for receiving from M2M devices both subscription requests and notifications, and for transmitting to M2M devices both subscription requests and notifications;
- a memory for storing a traffic table;
- and
- a processor for determining if a subscription request received over the communications interface is directed to a second event associated with a resource with which a plurality of previous subscriptions have been registered for first events, the first and second events being different from each other, for closing a session associated with the previous subscriptions with the resource responsive to the determination, for causing the communications interface to transmit a new subscription determined in accordance with the previous subscriptions and the received subscription request, the new subscription being associated with the first and second events, and for updating the traffic table based on the closing of the session associated with the previous subscriptions and on the transmitting of the new subscription to the resource.
