Abstract

Methods executed in a server in a communication network are provided. The server handles messages for at least one client and/or application. The method includes identifying deterioration in a connectivity or reachability between the server and the at least one client and/or application; and transmitting a re-establishment message to the at least one client and/or application. The message makes or enables the at least one client and/or application reestablish the connectivity or reachability. Related devices are also provided herein.

Claims

1. A method, executed in a server in a communication network, the server handling messages for at least one client and/or application, the method comprising:

identifying a deterioration in a connectivity or reachability between the server and the at least one client and/or application; and

transmitting a re-establishment message to the at least one client and/or application, the message making or enabling the at least one client and/or application re-establish the connectivity or reachability

2. The method of claim 1, wherein the connectivity or reachability is established via or through a pinhole in a firewall.

3. The method of claim 2, wherein the deterioration is a termination of an open state of the pinhole.

4. The method of claim 1, wherein the deterioration is an interruption of the connectivity or reachability.

5. The method of claim 1, wherein the deterioration is identified by the server.

6. The method of claim 1, further comprising transmitting the re-establishment message from the server to the at least one client and/or application.

7. The method of claim 1, wherein the connectivity or reachability is re-established to a state it had before the deterioration.

8. The method of claim 1, wherein identifying a deterioration in a connectivity or reachability is preceded by:

establishing a connectivity or reachability between the at least one client, and/or application and the server, and

registering, or making available, a terminal address and a client communication port identifier of the at least one client at or for the server.

9. The method of claim 8:

wherein the terminal address is the Mobile Subscriber Integrated Services Digital Network Number (MSISDN) of a terminal of the at least one client; and

wherein the client communication port identifier relates to a client communication port being a WAP Push port of the at least one client and/or application.

10. A server arrangement in a server for handling messages for at least one client and/or application, the server arrangement comprising:

an identifying element for identifying a deterioration in a connectivity or reachability between the server and the at least one client and/or application, and

a transmitting element for transmitting a re-establishment message to the at least one client and/or application, the re-establishment message making or enabling the at least one client and/or application re-establish the connectivity or reachability.

11. The server arrangement of claim 10, wherein the connectivity or reachability is established via or through a pinhole in a firewall.

12. The server arrangement of claim 11, wherein the deterioration is a termination of an open state of the pinhole.

13. The server arrangement of claim 10, wherein the identifying element is adapted to identify an interruption in the connectivity or reachability.

14. The server arrangement of claim 10, wherein the transmitting element is adapted to transmit the re-establishment message from the server to the at least one client and/or application.

15. The server arrangement of claim 10, wherein the transmitting element is adapted to transmit a re-establishment message that makes or enables at least one client and/or application re-establish the connectivity or reachability to a state it had before the deterioration.

16. The server arrangement of claim 10, wherein the arrangement comprises:

an establishing element adapted to establish a connectivity or reachability between at least one client and/or application and the server; and

a registering element for registering, or making available, a terminal address and a client communication port identifier of the at least one client and/or application at or for the server.

17. The server arrangement of claim 10, wherein the registering element is adapted to retrieve or receive the terminal address and the client communication port identifier from the at least one client and/or from a database.

18. The server arrangement of claim 16:

wherein the terminal address is the Mobile Subscriber Integrated Services Digital Network Number of the terminal of the at least one client; and

wherein the client communication port identifier relates to a client communication port being a WAP Push port of the at least one client and/or application.

19. A method, executed in a client and/or application in a communication network, the client and/or application handling connectivity or reachability with or towards at least one server, the method comprising:

establishing connectivity or reachability between the client and/or application and the at least one server; and

transmitting a registration message to the server, the registration message including a client communication port identifier and optionally a terminal address of the client and/or application.

20. The method of claim 19, wherein the connectivity or reachability is established via or through a pinhole in a firewall.

21. The method of claim 19, wherein the deterioration is a termination of an open state of the pinhole.

22. The method of claim 19 comprising receiving, at the client and/or application, a re-establishment message enabling or making the client and/or application to re-establish the connectivity or reachability with or towards the at least one server.

23. The method of claim 19 further comprising receiving, at the client and/or application, the re-establishment message from the at least one server or from an additional server.

24. The method of claim 19 further comprising registering the client and/or application for listening on or to an available communication port of the terminal on which the client and/or application resides, wherein registering the client and/or application for listening possibly precedes establishing connectivity or reachability.

25. The method of claim 19, wherein the client includes a platform, and wherein the platform participated in the establishing, the transmitting, the receiving and the registering.

26. A client arrangement in a terminal in a communication network, the terminal comprising at least one client and being adapted to handle connectivity or reachability with or towards at least one server, the client arrangement comprising:

a client establishing element adapted for establishing connectivity or reachability between a client and/or application and the at least one server, and

a client transmitting element adapted for transmitting a registration message to the at least one server, the registration message including a client communication port identifier and, optionally, a terminal address of the client.

27. The client arrangement of claim 26, wherein the connectivity or reachability is established via or through a pinhole in a firewall.

28. The client arrangement of claim 27, wherein the deterioration is a termination of an open state of the pinhole.

29. The client arrangement of claim 26 further comprising a client receiving element adapted for receiving a re-establishment message enabling or making the client to re-establish the connectivity or reachability with or towards said the at least one server.

30. The client arrangement of claim 26, wherein the client receiving element is adapted to receive the re-establishment message from the at least one server or from an additional server.

31. The client arrangement of claim 26 further comprising a client registering element adapted so that the client and/or application can register itself for listening on or to an available communication port of the terminal on which the client and/or application resides.

32. The client arrangement of claim 26, wherein at least one of the client elements of the client arrangement is included in or on a platform of or in the client.
