Abstract

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.

a) providing, by the wireless terminal device, a directory for use by the plural code components installed on the wireless terminal device to advertise services offered by the plural code components and to request access by the plural code components to the advertised services;

b) upon receiving a request for access by a first code component of the plural code components to a first advertised service of the advertised services, determining, by the wireless terminal device, whether the first code component is granted a permission to access the first advertised service; and

c) upon determining that the first code component is granted the permission, directly communicatively coupling, by the wireless terminal device, the first code component to a second code component offering the first advertised service, the second code component belonging to the plural code components, wherein the first and second code components utilize a standardized communication interface for facilitating the direct communicative coupling,

wherein determining whether the first code component is granted the permission to access the first advertised service comprises automatically determining whether the first code component and the second code component were generated using compatible API file versions, including a first hash value with the first code component and including a second hash value with the second code component, the first hash value generated from an API file used to generate the first code component, the second hash value generated from an API file used to generate the second code component, and

wherein determining whether the first code component and the second code component were generated using compatible API file versions comprises comparing the first hash value with the second hash value.

2. The method of claim 1, wherein the first code component is written in a different programming language than the second code component.

3. The method of claim 1, wherein the first code component and the second code component form parts of a single program application.

4. The method of claim 1, wherein the first code component and the second code component correspond to two different interacting program applications.

5. The method of claim 1, wherein the first component is associated with a first sandbox environment and the second component is associated with a second sandbox environment separate from the first sandbox environment.

6. The method of claim 1, wherein the first component is associated with a first sandbox environment and the second component is associated with a second sandbox environment, and wherein the first sandbox environment is embedded within the second sandbox environment.

7. The method of claim 1, wherein at least one of the first component and the second component is associated with a sandbox environment, the method further comprising creating a file system as part of the sandbox environment, wherein the files system is a Temporary File System (TMPFS) or a Random Access Memory File System (RAMFS).

8. The method of claim 7, further comprising bind mounting a predetermined set of files within the file system, the predetermined set of files configured to support operation of the at least one of the first component and the second component.

9. The method of claim 1, wherein the first code component is associated with a first User ID and the second code component is associated with a second User ID, the method further comprising identifying the first code component using the first User ID and identifying the second code component using the second User ID.

10. The method of claim 1, wherein directly communicatively coupling the first code component to the second code component comprises creating a linked pair of file descriptors for facilitating message passing, and providing a first one of the pair of file descriptors to the first code component and providing a second one or the pair of file descriptors to the second code component.

11. A wireless terminal device, comprising:

a) a memory having an operating system and plural code components installed thereon;

b) a service directory installed in the memory for use by the plural code components installed on the wireless terminal device to advertise services offered by the plural code components and to request access to the advertised services; and

c) a supervisory module installed in the memory and configured, upon receiving a request for access by a first code component of the plural code components to a first advertised service of the advertised services, to determine whether the first code component is granted a permission to access the first advertised service, the supervisory module further configured, upon determining that the first code component is granted the permission, to directly communicatively couple the first code component to a second code component offering the first advertised service, the second code component belonging to the plural code components, wherein the first and second code components utilize a standardized communication interface for facilitating the direct communicative coupling,

wherein determining whether the first code component is granted the permission to access the first advertised service comprises automatically determining whether the first code component and the second code component were generated using compatible API file versions, including a first hash value with the first code component and including a second hash value with the second code component, the first hash value generated from an API file used to generate the first code component, the second hash value generated from an API file used to generate the second code component, and

wherein determining whether the first code component and the second code component were generated using compatible API file versions comprises comparing the first hash value with the second hash value.
