Description

Remote management method and system of wireless communication terminal {METHOD AND SYSTEM FOR REMOTE MANAGEMENT IN MOBILE COMMUNICATION TERMINAL}

The present invention relates to a method and system for managing a wireless communication terminal, and more particularly, to a method and system for remotely managing a wireless communication terminal.

As the number of wireless communication terminals has increased exponentially, a standardized method for managing wireless communication devices has been needed. A wireless service provider or a service provider communicates with terminals wirelessly, and the firmware, A mobile device management method has been developed for managing software, parameters, schedules, and hardware features (Firmware, Software, Parameter, Schedule, Capabilities). One of them is OMA DM (Device Management) developed by the Open Mobile Alliance, which makes application standards for wireless communication terminals. OMA DM can manage firmware, software, parameters, etc. in the terminal by reading, adding, deleting, changing, and executing an object of the wireless communication terminal using the DM protocol based on SyncML. The subject managing a device such as a wireless communication terminal is a DM server, and the device to be managed like a wireless communication terminal is a client.

Conventional device management methods operate in a one-to-one manner. That is, the DM server causes the DM client to add / delete a specific configuration to the terminal by creating a one-to-one session between the DM server on the network and the DM client provided in the wireless communication terminal to exchange messages defined in the DM protocol. / Change or perform a specific action.

The DM protocol is defined as a total of five messages from package # 0 to package # 4, and a DM session may be formed between the DM server and the device through the DM protocol. At this time, the DM session may be initiated by a DM server or a client, that is, a device.

1 is a diagram illustrating a general DM session setup process.

Referring to FIG. 1, when there is a management operation to be performed on a specific device, the DM server 20 sends a package # 0 notification message to the DM client 10 provided in the specific device, that is, the specific device in step 101. It sends a Notification Message to indicate that a DM action exists. Upon receiving the package # 0 notification message, the DM client 10 sends a package # 1 message to the DM server 20 in step 103 to request session establishment. The DM server 20 transmits a package # 2 message to the DM client 10 in step 105 for allowing the DM session to be set up and for transmitting a DM command for waiting management operation. In response to the package # 2 message, the DM client 10 transmits a package # 3 message to the DM server 20 to deliver a result of the execution of the DM command received from the server in step 107.

Subsequently, the DM server 20 terminates the DM session through the package # 4 message in step 109, or delivers an additional management operation to the DM client 10, and the DM client 10 sends a package # 4 message. Perform additional management operations included in the and report the result to the DM server 20 through the package # 3 message. Thereafter, the DM server 20 and the client may provide management operations or management commands through repetition of the package # 4 message and the package # 3 message. In this case, the DM session is maintained if a management operation is continuously included in the package # 4 message. Also, if there is no additional management operation, the DM session is terminated.

In addition, the DM server 20 needs to know the structure of the DM tree inside the wireless communication terminal equipped with the DM client 10 in order to perform a specific management operation on the DM client 10. The DM tree represents a structure of a management object (MO) inside the wireless communication terminal in a tree form, and the MO is a means for exposing parameters and objects inside the terminal to the DM server 10.

4 shows an example of a DM tree inside a wireless communication terminal. Referring to Fig. 4, the set of nodes of the tree structure below the Diagnostics node 401 forms one MO. That is, the MO formed by the lower nodes of the Diagnostics node 401 represents the structure of the OMA DiagMon MO.

The structure of such a MO may be defined by anyone such as a service provider or a terminal vendor, and the defined MO structure enables to identify its structure by having a specific MO ID. And all of the structure of the MO corresponding to the MO ID is registered and managed in a specific server, for example, OMNA, so that the structure of the MO defined by someone can be represented by the MO ID registered in the OMNA. That is, the MO corresponding to one MO ID has the same configuration and structure regardless of the type of the wireless communication terminal.

However, the structure of the DM tree may be different for each wireless communication terminal. In other words, although the type and connection relationship of nodes constituting one particular MO are maintained, the position of the specific MO in the DM tree may be different for each wireless communication terminal. Accordingly, in order to deliver a DM message to a specific wireless communication terminal, the conventional DM server 20 has a structure of a DM tree inside the specific wireless communication terminal and a location of a specific MO node to perform a DM command. It is necessary to know information about a local uniform resource identifier (URI) of the specific node. Such a local URI may be obtained through a device description framework (DDF) provided by a wireless communication terminal or a GET command after a DM session is formed.

The DM server 20 performs a management task by delivering a specific command to a specific MO node on the DM tree of the wireless communication terminal using the DM protocol. Therefore, when a ReportingCondition / Frequency is set to 1 for a specific Diagnostics function represented by the Diagnostics MO of the wireless communication terminal having the DM tree of FIG. 4, the DM server 20 is a corresponding node, that is, ReportingCondition / Frequency. The Replace command is sent to the node 403. And if you want to run the Start node 405 to start the execution of the Diagnostics MO, the DM server 20 transmits a DM message targeting the corresponding Start node 405 using the DM protocol of FIG. At this time, the DM mesh includes a local URI address indicating the position in the tree of the node that is the target of the DM command, as shown in Table 1 below. Table 1 shows an example of a DM message indicating such an operation. Only the parts directly related to the contents of the DM command are described.

<Replace>-<Target> < LocURI > ./ SamsungFunctions / Diagnostics / 1 / DiagMonConfig / ReportCondition / Frequency </ LocURI > </ Source><Data> 1 <Data></Replace><Exec>-<Target><LocURI> ./ SamsungFunctions / Diagnostics / 1 / Operation / Start </ LocURI></Source><Exec>

As described above, the conventional device management is performed through the one-to-one method between the DM server 20 and the wireless communication terminal, and the DM server 20 has to know the DM tree structure of the corresponding wireless communication terminal. Therefore, even when the same DM command is transmitted to a plurality of wireless communication terminals, the DM server 20 must establish a one-to-one session with each wireless communication terminal, which wastes radio resources. In addition, there is a hassle that the DM server 20 should grasp the DM tree structure of each wireless communication terminal.

Therefore, there is a need for a method that can simultaneously transmit the same DM command to multiple wireless communication terminals.

Accordingly, the present invention provides a method and system that can easily deliver the same DM command to multiple wireless communication terminals.

And the present invention provides a method and system that can reduce the consumption of radio resources when delivering the same DM command to multiple wireless communication terminals.

The present invention also provides a method and system capable of delivering the same DM operation to a plurality of wireless communication terminals by using a broadcasting transport port.

The present invention also provides a method and system in which a plurality of wireless communication terminals having different structures of the DM tree can perform the same DM action.

The present invention relates to an arbitrary device management (DM) command for function management of a wireless communication terminal by a device management server, a MO ID of a management object (MO) associated with an arbitrary node to perform the arbitrary DM command, and the optional Constructing and broadcasting a DM message including node information about a node of the node; and receiving a DM message by a DM client of a wireless communication terminal, by using the MO ID and the node information included in the DM message. And identifying a position of the arbitrary node in a DM tree representing a MO structure inside the wireless communication terminal in a tree form, and performing the arbitrary DM command in the arbitrary node.

In the present invention, the node information includes node MO position information indicating the position of the arbitrary node within the node tree structure of the related MO.

In the present invention, the DM client performing the arbitrary DM command may include receiving the DM message, detecting the MO ID in the DM message, and corresponding to the MO ID in the DM tree. Determining the location of the root node of the MO, using the determined root node location and the node MO location information, identifying the location of the arbitrary node in the DM tree, and at the arbitrary node. Performing any of the DM commands.

In the present invention, the MO ID is included as independent reference position information in the MO message, and the node MO position information is included in the target URI as relative position information.

Alternatively, in the present invention, the MO ID is included as part of a local URI in the MO message.

The present invention includes the MO ID of the MO including the node that is the target of the DM command in the DM message, and transmits the same DM command to a plurality of wireless communication terminals by transmitting the same through the broadcasting transmission port. Therefore, waste of radio resources can be prevented. The plurality of wireless communication terminals having different structures of the DM tree may perform the same DM action.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the same components in the drawings are represented by the same reference numerals and symbols as much as possible even though they are shown in different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The wireless communication terminal provides a user with various communication services provided by the communication system, for example, voice and video communication services, messaging services, and wireless data services. The wireless communication terminal has various functions related to various communication services, and various additional functions except communication functions such as a phone book, an alarm function, a game function, a music playback function, and a schedule management function.

And the detailed conditions of each communication service and function described above may be changed. For example, you can set details related to communication services such as incoming / outgoing restriction of various communication, restriction of user data access, incoming call forwarding service, automatic answering, incoming and outgoing message notification method, incoming call notification sound. It is possible to set detailed conditions of various additional functions such as display-related detailed settings, phone book-related detailed settings, alarm settings, and schedule management. In the following description of the present invention, various setting conditions that can be changed in connection with various communication services and various functions provided by the wireless communication terminal are referred to as configuration parameters.

According to the present invention, a DM server transmits a DM message to a plurality of wireless communication terminals by using a one-to-many transport, and the DM client of the wireless communication terminal receiving the DM message interprets the DM message. After that, take the appropriate action. However, since the structure of the DM tree inside the plurality of wireless communication terminals may be different from each other, the DM message transmitted to them cannot specify the complete URI of a specific node as in the prior art.

Meanwhile, a MO (Management Object), which is a set of nodes performing a specific function, has a unique MO ID. That is, SCOMO (Software Component Management Management Object) for performing Software Component Management has a unique MO ID, and the MO ID is the same no matter where the MO is located in the DM Tree of the wireless communication terminal. It is maintained, and the type or connection relationship of the lower nodes constituting the MO are not changed. Therefore, even in a wireless communication terminal having a different DM tree structure, the MO indicated by each specific MO ID is the same, and since each wireless communication terminal knows its own DM tree structure, the MO indicated by the specific MO ID You can see where is the root node of.

The present invention constructs a DM message using this characteristic, so that a plurality of wireless communication terminals receive the same DM message, and interpret the DM message according to its DM tree structure to perform a DM command.

2 shows an example of the configuration of a remote management system to which the present invention is applied. Referring to FIG. 2, the remote management system includes a first DM server 110, wireless mobile communication terminals 130, 140, and 150, and a wired / wireless communication network 120.

The first DM server 110 includes a DM command for requesting to read, add, change, or execute an object related to firmware, software, parameters, etc. in order to manage firmware, software, parameters, etc. in various wireless communication terminals. Create a DM message. According to the present invention, the first DM server 110 includes a DM command to be performed in a DM message, a MO ID of a MO associated with a specific node to which the DM command is applied, and transmits the DM message through a broadcasting transmission port. Broadcast. At this time, the DM message includes node MO location information which is location information of the specific node in the related MO.

The MO ID informs the reference position of the local URI of the node to which the DM command is to be applied. In other words, when the wireless communication terminals 130, 140, and 150 receive the DM message, each wireless communication terminal uses the MO ID included in the DM message, and thus, a root node of the MO corresponding to the MO ID in the DM tree. ) Can be located. The location of the root node and the node location information thus determined can determine the complete location of the node to which the DM command included in the DM message is applied.

The wireless communication terminals 130, 140, and 150 are terminals for performing various wireless communication, and each includes a device management client 131. The DM client 131 communicates with the first DM server 110 through a DM protocol, and transmits and receives information necessary for managing the wireless communication terminal with the first DM server 110 to manage the wireless communication terminal. In addition, the DM client 131 uses the MO ID included in the DM message transmitted through the broadcasting transmission port channel according to the present invention to determine the location of the node to which the DM command included in the DM message is to be applied, and receives the received DM. Perform the DM command contained in the message.

3 illustrates an operation process of the first DM server 110 and the first DM client 131.

Referring to FIG. 3, in step 201, the first DM server 110 performs a DM command to be performed according to the present invention, an MO ID of a MO associated with a specific node to execute the DM command, and node MO 'position information of the specific node. Configure a DM message comprising a.

 According to an embodiment of the present invention, the MO ID may be included as reference location information in the DM message, or according to another embodiment of the present invention, may be included as part of a conventional local URI.

First, according to one embodiment of the present invention, when a MO ID is included as reference location information in a DM message, the MO ID is specified as information separate from the local URI. The node MO location information, which is the location information in the corresponding MO of the node to perform the DM command, is included in the target URI and may be included as a part of the local URI of the target URI in the form of a relative URI. In this case, the relative URI may be identified by a predetermined special symbol. An example of this case is shown in Table 2.

The DM message shown in Table 2 is to set ReportingCondition / Frequency to 1 for a specific Diagnostics function indicated by the Diagnostics MO, and execute a Start node 405 to start execution of the corresponding Diagnostics MO. The MO ID of the Diagnostics MO is "urn: oma: mo: oma-diagmon: 1.0" and the identifier for the relative URI is "../".

<!-Indicate Base MO of the following commands-> <Base> MO ID: urn: oma: mo: oma-diagmon: 1.0 <Replace>-<Target><LocURI> ../1/DiagMonConfig/ReportCondition/ Frequency </ LocURI></Source><Data> 1 <Data></Replace><Exec>-<Target><LocURI> ../1/Operation/Start </ LocURI></Source><Exec>

 In the DM message according to an embodiment of the present invention, the relative URI may be assigned an identification tag, which is shown in Table 3. In Table 3, the identification tag of the relative URI is "<RelURI>".

<!-Indicate Base MO of the following commands-> <Base> MO ID: urn: oma: mo: oma-diagmon: 1.0 <Replace>-<Target> < RelURI > 1 / DiagMonConfig / ReportCondition / Frequency </ RelURI > </ Source><Data> 1 <Data></Replace><Exec>-<Target> < RelURI > / 1 / Operation / Start < RelURI > </ Source><Exec>

3, the first DM server 110 broadcasts the DM message configured as described above in step 203 through a broadcasting transmission channel.

As the wireless communication terminal 130, 140, or 150 receives the broadcasted DM message in step 205, the first DM client 131 detects the MO ID included in the DM message in step 207. Thereafter, in step 209, the first DM client 131 determines the location of the root node of the MO corresponding to the MO ID in the DM tree of the wireless communication terminal 130, 140, or 150 mounted therewith, and then in step 211. Complete the final local URI for. In step 213, the DM command included in the DM message is executed in the node located at the final local URI. The execution result is reported to the first DM server 110 according to a request or a basic setting of the first DM server 110.

When the wireless communication terminal having the DM tree structure shown in FIG. 4 receives the DM message configured as shown in Table 2 or Table 3, the DM message interpreted by the first DM client 131 is shown in Table 4.

<-! Omit irrelevant parts-><Replace>-<Target><LocURI> ./SamsungFunctions/Diagnostics/ 1 / DiagMonConfig / ReportCondition / Frequency </ LocURI></Source><Data> 1 <Data></Replace><Exec>-<Target><LocURI> ./SamsungFunctions/Diagnostics/ 1 / Operation / Start </ LocURI></Source><Exec>

This is because, in Fig. 4, the position of the root node 401 of the Diagnostics MO indicated by the MO ID "urn: oma: mo: oma-diagmon: 1.0" is "./SamsungFunctions/Diagnostics".

As another example, in the case of a wireless communication terminal having a DM tree as shown in FIG. 5, a DM message as shown in Table 2 or Table 3 is interpreted as shown in Table 5.

<-! Omit irrelevant parts-><Replace>-<Target><LocURI> ./Diag/ 1 / DiagMonConfig / ReportCondition / Frequency </ LocURI></Source><Data> 1 <Data></Replace><Exec>-<Target><LocURI> ./ Diag / 1 / Operation / Start </ LocURI></Source><Exec>

In the DM tree of FIG. 5, the MO corresponding to MO ID "urn: oma: mo: oma-diagmon: 1.0" is Diag MO, which is the same MO as "Diagnostics" of FIG. Therefore, the position of the root node 501 of the Diag MO indicated by the MO ID "urn: oma: mo: oma-diagmon: 1.0" becomes "./Diag".

As such, therefore, the first DM client 131 receiving the DM message shown in Table 2 or Table 3 is the DM tree of the wireless communication terminal in which all of the mounted DMs are located regardless of the position of DiagMon MO in the actual DM tree. After the analysis, the frequency (403 EH is set to 503) is set to 1, and then the start operation (405 or 505) of the corresponding DiagMon MO is performed.

Meanwhile, according to another embodiment of the present invention, the MO ID may be included as part of the local URI in the DM message. This is shown in Table 6. The DM command contents of the DM messages shown in Table 6 are the same as in Table 2 or Table 3.

<!-Send DM commands based on the MOID as a root-><Replace>-<Target><LocURI> urn: oma: mo: oma-diagmon: 1.0 / 1 / DiagMonConfig / ReportCondition / Frequency </ LocURI></Source><Data> 1 <Data></Replace><Exec>-<Target><LocURI> urn: oma : mo: oma - diagmon : 1.0 / 1 / Operation / Start </ LocURI></Source><Exec>

As shown in Table 6, the MO ID is inserted before the local URI of the target URI. Upon receiving this, when the first DM client 131 confirms that the MO ID is located in the local URI portion, the first DM client 131 determines the location of the root node of the corresponding MO. By combining the location of the identified root node with the local URI, it interprets the DM message by reinterpreting it accordingly. The analysis result can be Table 4 or Table 5.
