The present invention provides methods, systems and computer program products for facilitating loading, configuration and interaction of modular applications and/or modular components of an application on wireless devices such as M2M terminals. Modular elements may be connected to each other based on a system of permissions which determines which elements are permitted to access given services offered by other elements. Once connected, modular elements may communicate directly via a standardized interface.

Wireless device customization resources

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.

Method and system for wireless communication with machine-to-machine devices

A method and system for forwarding data between network devices is provided. A routing device receives, identifies and forwards data to a network device coupled to a private network. The routing device may make a determination of how to forward the data, for example by determining which of several delivery mechanisms to use. The network device may be also associated with a public network via a public network device identifier (PNDI). The PNDI may include a public IP address of the routing device, a public first port number such as a destination port number, and optionally a public second port number such as a source port number, the combination of public IP address and public port number(s) being unique to the network device.

Method and system for forwarding data between network devices

The present invention provides a method and apparatus for network port and network address translation. Several problems with limited addressability may occur when transmitting data packets between a terminal in a first network and a terminal in a second network that is outside the first network. Data forwarding rules are used to define if and how identifiers of data packets to be forwarded between the two networks correlate with each other. According to embodiments, a data forwarding rule includes a first identifier associated with the first network and a second identifier associated with the second network, wherein each identifier has two parts: a source address and source port number corresponding to a source network node, and a destination address and destination port number corresponding to a destination network node.
