Abstract

A radio handset which includes a processor having a memory, for performing the functions of the handset by communicating between originating entities and destination entities. Some of the entities being within the handset and at least one being locatable within an ancillary device. The handset further includes an interface coupled to the processor having a radio transceiver arranged for coupling to the ancillary device and communicating therewith to enhance the functions of the handset, and routing apparatus, coupled to the processor. The routing apparatus is arranged to provide communication between an entity in the handset and an entity in the ancillary device by enabling the creation of a proxy entity in the handset for transaction with the entity in the handset.

Claims

1. A radio handset comprising:

processor means including memory, for performing functions of the handset by communicating between originating entities and destination entities, some of said entities being within the handset and at least one entity being locatable within an ancillary device;

an interface coupled to the processor means and having a radio transceiver arranged for coupling to the ancillary device and communicating therewith to enhance the functions of the handset; and

routing means, coupled to the processor means, and arranged to provide for communication between an entity in the handset and an entity in the ancillary device by enabling the creation of a proxy entity in the handset for transaction with the entity in the handset, the creation of the proxy entity in the ancillary device being for transaction with the entity in the ancillary device and for communication between the handset and ancillary device through the interface.

2. A radio handset as claimed in claim 1, wherein the routing means is arranged to associate each entity within the handset with a task and to provide for communication between an originating entity in an originating task and a destination entity in a destination task by using one or more intra-task transactions and, if necessary, inter-task communication, each transaction involving two entities associated with a same task, said routing means being arranged to provide for communication between an originating entity and a destination entity by enabling, if the originating and destination tasks are the same, the transaction of the originating entity and of the destination entity and by enabling, if the originating and the destination tasks are different, the creation of a proxy entity in the originating task for a transaction with the originating entity, and if necessary, the creation of a proxy entity in the destination task being for the transaction with the destination entity and for communication between the originating and destination tasks via the interface.

3. A radio handset as claimed in claim 1, wherein said originating entity is arranged to request a service using a symbolic address identifying the service and the routing means is arranged to determine from the symbolic address if the service is provided within the handset.

4. A radio handset as claimed in claim 3, wherein the routing means is arranged to determine from the symbolic address if the service is provided within the originating task.

5. A radio handset as claimed in claim 1, wherein said routing means addresses the request to the destination entity providing the identified service or to the proxy entity representing the destination entity in the handset.

6. A radio handset as claimed in claim 5, wherein said routing means addresses the request to the destination entity providing the identified service or to the proxy entity representing the destination entity in the originating task.

7. A radio handset as claimed in claim 1, wherein the originating entity is defined within the processor means.

8. A radio handset as claimed in claim 1, wherein the destination entity is defined within the processor means.

9. A radio handset as claimed in claim 2, wherein the originating entity is a first object, which is a first specialization of a base class, and the destination object is second object, which is a second specialization of the base class.

10. A radio handset as claimed in claim 9, wherein the proxy entity is a third object, being a third specialisation of the base class.

11. A radio handset as claimed in claim 10, wherein the third object encapsulates a means of communication between the handset and ancillary device.

12. A radio handset as claimed in claim 11, wherein the third object encapsulates a means for providing inter-task communication.

13. A radio handset as claimed in claim 9, wherein the second object encapsulates a resource for providing a service.

14. A radio handset as claimed in claim 9, wherein the first object is arranged to request services from any one of a plurality of second objects.

15. A radio handset as claimed in claim 9, wherein a transaction comprises one object calling a function in another object, the objects being in either the handset or the ancillary device.

16. A radio handset as claimed in claim 15, wherein a transaction comprises one object calling a function in another object, the objects being within a same task.

17. A radio handset as claimed in claim 16, wherein the function called in a transaction has as arguments a pointer to or an address of each of the objects within the same task.

18. A modular system comprising distributed modules including a radio handset and an ancillary device, said radio handset and ancillary device being arranged to use radio communication to enhance the handset'"'"'s functionality,

the radio handset comprising:

processor means including memory, for performing functions of the handset by communicating between originating entities and destination entities, some of said entities being within the handset and at least one entity being within the ancillary device;

a first interface coupled to the processor means and having a radio transceiver arranged for coupling to the ancillary device and communicating therewith to enhance the functions of the handset;

first routing means, coupled to the processor means, and arranged to provide for communication between the originating entities and the destination entities using one or more transactions and, if necessary, communication to the ancillary device, at least one transaction involving two entities within the handset; and

wherein the ancillary device comprises

at least one entity;

a second interface having a radio transceiver for communicating with the first interface;

second routing means arranged to provide for communication between the originating entities and the destination entities using one or more transactions and, if necessary, communication with the handset, at least one transaction involving two entities in the ancillary device; and

said first and second routing means being arranged to provide for communication between an entity in the radio handset and the entity in the ancillary device by enabling the creation of a proxy entity in the handset for transaction with the entity in the handset, the creation of a proxy entity in the ancillary device being for transaction with the entity in the ancillary device and for communication between the handset and ancillary device via the interface.

19. An ancillary device for augmenting functionality of a radio handset which performs functions thereof by communicating between originating entities and destination entities, some of said entities being within the handset, comprising:

at least one entity;

a second interface having a radio transceiver for communicating with the radio handset; and

routing means arranged to provide for communication between the originating entities and the destination entities using one or more transactions and, if necessary, communication with the handset, at least one transaction involving two entities in the ancillary device, wherein the routing means is arranged to provide for communication between an entity in the radio handset and the entity in the ancillary device by creating a proxy entity in the ancillary device for transacting with the entity in the ancillary device and communicating via the interface.
