Abstract

Provided are methods for handling reports on lost connections in a terminal device which is capable of being in communication connection with a plurality of network access nodes, wherein the terminal device generates, after having lost connection to a (first) network access node, a report on the loss of connection and, upon or after reconnecting of the terminal device with the same or a different network access node, sends the report on the loss of connection to the network access node. The network access node receiving a report on loss of connection from a terminal device, forwards said report to a central server and/or to a network access node to which the terminal device was connected before. Further provided are a terminal device comprising a receiver and a transmitter and being adapted to connect to an access node of a network, particularly of a wireless, e.g. a cellular radio network, said terminal device further comprising a report generator for generating a report on a loss of connection, wherein said transmitter is adapted to send said report to an access node upon or after reconnecting, and a network access node, particularly a network access node of a wireless, e.g. a cellular radio network, comprising a receiver and a transmitter and being adapted to be connected by a terminal device, wherein the receiver is adapted to receive reports on a loss of connection from a terminal device, and wherein the transmitter is adapted to forward or send a received report to a central server or to a different access node, particularly to an access node to which the terminal was connected before a loss of connection.

First claim

The invention claimed is:

1. A method for handling reports on lost connections in a terminal device which is capable of being in communication connection with a plurality of network access nodes, wherein the terminal device performs the following steps:
after having lost connection to a first network access node, generating a report on the loss of connection,
storing the report when the terminal device is reconnected to a third network access node comprising one of a different access technology, a different network, and a different network operator than the first network access node to which the terminal device was connected before the loss of connection, and
upon or after reconnecting with one of the first and a second network access node, sending the report to one of the first and second network access nodes.

2. The method according to claim 1 , wherein said report is stored for at least one of a predetermined amount of time, a dynamically adapted amount of time, and until a memory usage in the terminal device reaches or exceeds one of a predetermined or dynamically adjusted level, and is then discarded.

3. The method according to claim 1 , wherein the terminal device, when reconnected to the second network access node, wherein the second network access node comprises at least one of the same access technology, the same network, and the same network operator as the first network access node, sends the report to said second network access node.

4. The method according to claim 1 , wherein the terminal device subsequently sends the report to a plurality of network access nodes.

5. The method according to claim 4 , wherein the report comprises an indicator on how many times the report has already be sent.

6. The method according to claim 1 , wherein the terminal device, when reconnected to the second or the third network access node that is an access node of a different access technology than the first network access node to which the terminal device was connected before the loss of connection, sends the report on loss of connection with a generic message type for the access technology of the second or third network access node.

7. The method according to claim 1 , wherein the report on loss of connection comprises address information including an IP address of at least one of a central server and the first network access node to which the terminal device was connected before the loss of connection.

8. A method for handling reports on lost connections in a network access node, wherein the network access node performs the following steps:
receiving a report on loss of connection from a terminal device, wherein the network access node comprises a different access node than a first access node to which the terminal device was connected before the loss of connection, and
forwarding or sending said report to at least one of a central server and a further network access node;
wherein the network access node receives the report on loss of connection relating to an access technology not supported by the network access node, and wherein said report is forwarded to one of a central server and the first network access node to which the terminal device was connected before the loss of connection.

9. The method according to claim 8 , wherein said report is forwarded or sent to at least one of the central server and the first network access node to which the user terminal was connected to before the loss of connection.

10. The method according to claim 8 , wherein said forwarding or sending is accomplished by an information management procedure.

11. The method according to claim 8 , wherein said forwarding or sending is accomplished by relayed sending via an additional network node.

12. The method according to claim 8 , further comprising obtaining or determining address information including an IP address of at least one of the central server, the further network access node, and the first network access node to which the terminal device was connected before the loss of connection.

13. The method according to claim 12 , wherein the address information of the further network access node or the first network access node to which the terminal device was connected before the loss of connection is determined based on automatic neighbor relation.

14. The method according to claim 8 , wherein the report on loss of connection comprises address information including an IP address of at least one of the central server and the first network access node to which the terminal device was connected before the loss of connection.

15. A terminal device comprising:
a receiver and a transmitter adapted to connect to a first network access node of a network,
a report generator for generating a report on a loss of connection after having lost connection to the first network access node, and
a memory for storing the report when the terminal device is reconnected to a third network access node comprising one of a different access technology, a different network, and a different network operator than the first network access node to which the terminal device was connected before the loss of connection,
wherein said transmitter is adapted to send said report upon or after reconnecting with one of the first and a second network access node.

16. The terminal device according to claim 15 , wherein said terminal device is adapted to connect to the access node of a wireless network of a cellular radio network.

17. A network access node comprising:
a receiver and a transmitter adapted to be connected to by a terminal device,
the receiver being adapted to receive reports on a loss of connection from the terminal device, wherein the network access node comprises a different access node than a first access node to which the terminal device was connected before the loss of connection, and
the transmitter being adapted to forward or send a received report to a central server or to a further network access node;
wherein the network access node receives the report on loss of connection relating to an access technology not supported by the network access node, and wherein said report is forwarded to one of a central server and the first network access node to which the terminal device was connected before the loss of connection.

18. The network access node according to claim 17 , wherein the network access node is configured to operate within a wireless network, including a cellular radio network.
