Methods and systems for enabling communication to and from asset tracking devices
First Claim
1. A method of forwarding information between a device and a first entity, comprising:
- receiving, at a network access point, a data packet from a source of data packets, the data packet having a header including a destination network address of the first entity;
determining whether the destination network address is a trusted destination network address by communicating the destination network address of the first entity to an authorization server; and
if the destination network address of the first entity is trusted, communicating the data packet to the destination network address of the first entity.

Abstract
Methods and systems for enabling communication include a third party wireless access point and authorization mechanism that forwards messages between an asset tracking device and a remote tracking entity based, at least in part, upon whether an outbound message contains a destination address that is on an approved list maintained by the authorization mechanism, and upon whether an inbound message contains a source address that is on an approved list maintained by the authorization mechanism. In further aspects of the present invention, error handling is provided for circumstances in which the destination or source addresses are not on the approved list maintained by the authorization mechanism.

7. A method of processing and communicating information at a tracking entity, comprising:
-
receiving, at the tracking entity, a forwarded data packet from a third party authorization server, the data packet having a header including a source identifier of a source of the data packet;
determining whether the source identifier is a trusted source identifier; and
if the source identifier is trusted, then communicating a control packet addressed to the source of the data packet to the third party authorization server. - View Dependent Claims (8, 9, 10)

11. A system for enabling communication, comprising:
-
a device having a wireless communication module;
a network access point, operable to wirelessly communicate with the device;
an authorization entity operable to communicate with the network access point; and
a trusted network address store coupled to the authorization entity;
wherein the device is operable to communicate a data packet to the network access point, the data packet having a header including a network address of a first entity;
the network access point is operable to receive the data packet communicated from the device and to communicate the data packet to the authorization entity;
the authorization entity is operable to communicate with the trusted network address store to determine whether the network address of the first entity stored in the trusted network address data store; and
wherein if the network address of the first entity is stored in the trusted network address data store, then the authorization entity responsive to an affirmative determination communicates the data packet to the network address of the first entity. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
