A method of handling a management object in a telecommunication device (3, 14), said telecommunication device (3, 14) performing the steps of: receiving a data object exceeding a predetermined data size from a device management server; storing the received data object as a first portion in a management object leaf node; characterized by: when the telecommunication device determines termination of the reception of the data object prior to the management object being completely received, holding the first portion in the management object leaf node after termination has been determined; receiving a GET command from the device management server to get information of the first portion; and transmitting the information of the first portion to the device management server; after the termination of the reception of the data object which is prior to the management object being completely received, receiving an INSERT command or a command including an INSERT element, which comprises a second portion of the data object, different from the first portion of the data object, for requesting the telecommunication device (3, 14) to insert the second portion of the data object into the management object leaf node, from the device management server; storing the second portion in the management object leaf node; and combining the first portion and the second portion when the data object has been completely received; wherein the first portion and the second portion respectively comprise at least one unit data, and each unit data has a data size less than or equal to the predetermined data size. receiving a data object exceeding a predetermined data size from a device management server; storing the received data object as a first portion in a management object leaf node; characterized by: when the telecommunication device determines termination of the reception of the data object prior to the management object being completely received, holding the first portion in the management object leaf node after termination has been determined; receiving a GET command from the device management server to get information of the first portion; and transmitting the information of the first portion to the device management server; when the telecommunication device determines termination of the reception of the data object prior to the management object being completely received, holding the first portion in the management object leaf node after termination has been determined; receiving a GET command from the device management server to get information of the first portion; and transmitting the information of the first portion to the device management server; after the termination of the reception of the data object which is prior to the management object being completely received, receiving an INSERT command or a command including an INSERT element, which comprises a second portion of the data object, different from the first portion of the data object, for requesting the telecommunication device (3, 14) to insert the second portion of the data object into the management object leaf node, from the device management server; storing the second portion in the management object leaf node; and combining the first portion and the second portion when the data object has been completely received; wherein the first portion and the second portion respectively comprise at least one unit data, and each unit data has a data size less than or equal to the predetermined data size.
