Abstract

Device Management (DM) client apparatus and DM server apparatus and methods for their operation in a communication system are provided. The method for operating the DM client apparatus in a communication system includes receiving a message from a DM server, determining if a response message should be suppressed based on the received message, if it is determined that the response message should be suppressed, suppressing the response message by not transmitting the response message to the DM server, if it is not determined that the response message should be suppressed, transmitting the response message to the DM server, and receiving another message from the DM server.

18. The method of claim 12, further comprising:

if it is not determined that the DM client should be instructed to suppress the response message, waiting for the response message to be received after the transmitting of the generated message; and

after receiving the response message, transmitting another message to the DM client.

19. The method of claim 18, wherein the other message transmitted to the DM client comprises an Open Mobile Alliance (OMA)-DM Package 2 message.

20. The method of claim 12, further comprising:

if it is determined that the DM client should be instructed to suppress the response message, transmitting another message to the DM client after the transmitting of the generated message, without waiting for the response message to be received.

21. The method of claim 20, wherein the other message transmitted to the DM client comprises an Open Mobile Alliance (OMA)-DM Package 2 message.
