Abstract

The invention relates to a method for updating software (sof) in different terminals (PEC, PAL), which are connected to a communications network (NET), said network allowing communication between the terminals. On request, the software state of software (sof) that is running on one of the terminals (PEC) is transmitted to the second terminal (PAL) via the communications network (NET) and software that is running on the second terminal (PAL), which corresponds to the software (sof) on the first terminal (PEC), is provided with the transmitted software state and continues to run on the second terminal (PAL) with the last current state of the first terminal (PEC). The software used is, for example, an agent software.

Claims

1. Method for updating software (sof) on different terminals (PEC, PAL) which are connected to a communication network (NET), with the software implementing a voice connection and/or data connection,

characterized in that

a) at the request of the user of a terminal at least the software state of the software (sof) running on at least one of the terminals (PEC) is transmitted over the communication network (NET) to the second terminal (PAL), and

b) software running on the second terminal (PAL) corresponding to the software (sof) on the first terminal (PEC) is provided which the current transmitted software state and continues to run on the second terminal (PAL) in the last state that was current on the first terminal (PEC).

2. Method in accordance with claim 1,

characterized in that the software on the second terminal (PAL) corresponding to the software (sof) on the first terminal (PEC) is transmitted from a memory location (PAL, SSE, SSD) onto the second terminal (PAL).

3. Method in accordance with claim 2,

characterized in that a software server (SSE) is used as the memory location of the software.

4. Method in accordance with claim 2,

characterized in that the terminal (PEC) on which the software (sof) originally ran is used as the storage location of the software (sof).

5. Method in accordance with claim 1, characterized in that, in step a) the software state is packed into a message which is transferred to the second terminal (PAL).

6. Method in accordance with claim 1, characterized in that an agent software is used as the software.

7. Method in accordance with claim 5,

characterized in that the message further contains the storage location of the software (sof) or in the case of software agents (sof) at least the name of the main class and the storage location of the class definitions of the agent.

8. Method in accordance with claim 1, characterized in that the request by the second terminal (PAL) is made via the communication network (NET) to the first terminal (PEC).

9. Method in accordance with claim 1, characterized in that the request is issued by means of the first terminal (PEC) on which the software (sof) is running.

10. Method in accordance with claim 1, characterized in that for the request a unique address of the terminal (PAL) to which the software (sof) and the software state is to be transferred, is transmitted to the software (sof).

11. Method in accordance with claim 10,

characterized in that an IP address of the terminal (PAL) is used as the address.

12. Method in accordance with claim 1, characterized in that, after arrival of the

request the software (sof) is stopped in its execution on the first terminal (PEC) and this or the software state is transferred to the second terminal (PAL).

13. Method in accordance with claim 12,

characterized in that a copy of the software with its current software state is created and this copy is transferred to the second terminal (PAL).

14. Method in accordance with claim 13,

characterized in that when the software is running correctly on the second terminal (PAL) the execution of the software (sof) is ended on the first device (PEC).

15. Method in accordance with claim 1, characterized in that, when all terminals are switched off (PEC, PAL) or when the software (sof) is deactivated on all terminals (PEC, PAL) this or the last current state is transferred over the communication network (NET) to a software server (SSE) connected to the communication network (NET) and is stored by this server.

16. Method in accordance with claim 1, characterized in that the same runtime environment for the software (sof) is used on the terminals (PEC, PAL) and the software server (SSE).

17. Method in accordance with claim 16,

characterized in that JAVA is used as the runtime environment.
