Abstract: A mobile device implements an inter-device inter-process communication (IPC) mechanism by which services on each device in a cluster group may be accessed by other devices in the cluster group using intra-device IPC calls. The inter-device IPC mechanism extends the existing intra-device IPC mechanism so that it may be used by existing applications across devices in the cluster group with little or no modification to the applications. A mobile device establishes pseudo-tokens for objects on the mobile device and pseudo-handlers for objects on the other devices. A mobile device may access multiple objects on other devices and may provide multiple other devices with access to a local object. Each object accessed via an inter-device IPC call is associated with a respective service adapter in a respective communication service gateway of each of the participating devices.
