Description

TECHNICAL FIELD [0001] The present invention relates to a method and system for remotely managing a wireless 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 increases exponentially, a standardized method for managing wireless communication devices is needed. A wireless service provider or a service provider communicates wirelessly with terminals, A Mobile Device Management method has been developed for managing software, parameters, schedules, H / W functions (Firmware, Software, Parameter, Schedule, Capabilities). Representative examples include OMA DM (Device Management) developed by the Open Mobile Alliance, which creates application standards for wireless communication terminals. The OMA DM can manage the firmware, software, parameters, etc. in the terminal by reading, adding, deleting, changing and executing the object of the wireless communication terminal using the DM protocol based on SyncML. A device that manages a device such as a wireless communication terminal is a DM server, and a device to be managed, such as a wireless communication terminal, is a client.

The conventional device management method operates in a peat-to-peat manner. That is, a one-to-one session is created between the DM server on the network and the DM client provided in the wireless communication terminal, and the DM server sends and receives a message defined in the DM protocol, thereby allowing the DM client to add / delete a specific configuration / Make changes or perform specific actions.

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

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

1, when there is a management operation to be performed on a specific device, the DM server 20 transmits a Package # 0 notification message (message) to a specific device, that is, the DM client 10 included in the specific device, (Notification Message) to notify that there is a DM action. 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 a session formation. The DM server 20 permits DM session setup and sends a Package # 2 message for delivering a DM command for a standby terminal management operation to the DM client 10 in step 105, The DM client 10 transmits a package # 3 message to the DM server 20 in order to deliver the execution result of the DM command received from the server in step 107 in response to the package # 2 message.

The DM server 10 then terminates the DM session through the Package # 4 message or delivers an additional management operation to the DM client 10 in step 109, And reports the result to the DM server 20 via the package # 3 message. Thereafter, the DM server 20 and the client can 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 the package # 4 message continuously contains a management operation. Also, if there is no additional management action, the DM session is terminated.

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

4 shows an example of a DM tree in the wireless communication terminal. Referring to FIG. 4, a set of nodes of the tree structure below the Diagnostics node 401 form one MO. That is, the MOs formed by the lower nodes of the diagnostics node 401 represent the structure of the OMA DiagMon MO.

The structure of such an MO can be defined by anyone, such as a service provider or a terminal vendor, and the defined MO structure allows identification of its structure by having a specific MO ID. And the structure of the MO corresponding to the MO ID is all 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, the types and connection relationships of the nodes constituting one specific MO are maintained, but the positions of specific MOs 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 within the specific wireless communication terminal and a location of a specific MO node to execute a DM command, It should know information about the local URI (local Uniform Resource Identifier) of the specific node. Such a local URI can be obtained through a DDF (Device Description Framework) provided by a wireless communication terminal, or via a GET command after forming a DM session.

The DM server 20 performs a management task by transmitting a specific command targeting a specific MO node on the DM tree of the wireless communication terminal using the DM protocol. Accordingly, when setting the Reporting Condition / Frequency to 1 for the specific Diagnostics function indicated by the Diagnostics MO of the wireless communication terminal having the DM tree of FIG. 4, the DM server 20 sets the reporting condition / And sends a Replace command to the node 403. If it is desired to execute the Start node 405 to start execution of the corresponding Diagnostics MO, the DM server 20 transmits a DM message targeting the 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 target node of the DM command as shown in Table 1 below. Table 1 is an example of a DM message indicating such an operation, and only DM directly relates to the contents of the command.

<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 has been performed through a one-to-one method between the DM server 20 and the wireless communication terminal, and the DM server 20 has only 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 has to establish a one-to-one session with each wireless communication terminal, resulting in a waste of wireless resources. In addition, there is a problem that the DM server 20 has to grasp the DM tree structure of each wireless communication terminal.

Therefore, there is a need for a method capable of simultaneously transmitting the same DM command to a plurality of wireless communication terminals.

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

The present invention also provides a method and system that can reduce the consumption of wireless resources when transmitting the same DM command to a plurality of wireless communication terminals.

The present invention provides a method and system for delivering the same DM operation to a plurality of wireless communication terminals using a broadcasting transmission port.

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

The present invention is characterized in that the device management server includes an arbitrary DM (Device Management) command for managing the function of the wireless communication terminal, an MO ID of a Management Object (MO) associated with an arbitrary node to execute the arbitrary DM command, Comprising the steps of: constructing and broadcasting a DM message including node information for a node of a wireless communication terminal, when the DM client of the wireless communication terminal receives the DM message, using the MO ID and the node information included in the DM message Determining a position of the arbitrary node in a DM tree representing the MO structure in the wireless communication terminal in a tree form, and performing the arbitrary DM command at the arbitrary node.

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

In the present invention, the step of the DM client performing the arbitrary DM command may include the steps of receiving the DM message, detecting the MO ID in the DM message, responding to the MO ID in the DM tree Determining the position of the root node of the MO in the DM tree using the position of the root node and the position of the node MO; And performing the arbitrary DM command.

Also, 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.

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

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

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. It is to be noted that the same components in the drawings are denoted by the same reference numerals and symbols as possible even if they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The wireless communication terminal provides various communication services provided by the communication system, for example, voice and video communication service, messaging service, wireless data service, and the like to the user. The wireless communication terminal has various functions related to various communication services and has various additional functions except for a communication function such as a phone book, an alarm function, a game function, a music reproduction 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 the details related to communication services such as setting of restrictions on incoming / outgoing communication of each type of communication, restriction of user data access, incoming call signaling service, automatic answer, call reception and message reception notification method, And it is possible to set detailed conditions of various additional functions such as display related setting, phone book setting, alarm setting, schedule management and so on. In the following description related to the present invention, various setting conditions that can be changed in connection with each kind of communication service and various functions provided by the wireless communication terminal as described above are referred to as configuration parameters.

The present invention allows a DM server to transmit a DM message to a plurality of wireless communication terminals using a one-to-many transport (1-to-many transport), and the DM client of the receiving wireless terminal interprets the DM message Then, take appropriate action corresponding to it. However, since the structure of the DM tree in the plurality of wireless communication terminals may be different from each other, the DM message transmitted to them can not specify the complete URI of the specific node as in the conventional case.

On the other hand, a management object (MO), which is a set of nodes performing a specific function, has a unique MO ID. That is, the SCOMO (Software Component Management Management Object) for performing software component management has a unique MO ID, and the MO ID is the same regardless of the position of the MO in the DM tree of the wireless communication terminal And the type and connection relationship of the lower nodes constituting the MO are not changed. Therefore, even when a wireless communication terminal having a different DM tree structure is used, the MOs indicated by the specific MO IDs are the same, and since each wireless communication terminal knows its DM tree structure, the MO It is possible to know the position of the root node of the root node.

According to the present invention, a plurality of wireless communication terminals receive the same DM message by interpreting the DM message in accordance with the DM tree structure of the wireless communication terminal, and configure the DM message to be executed by constructing the DM message using this characteristic.

An example of the configuration of the remote management system to which the present invention is applied is shown in FIG. 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 reading, adding, changing, and executing an object related to firmware, software, parameters, etc. in order to manage firmware, software, parameters and the like in various wireless communication terminals DM message. According to the present invention, the first DM server 110 includes a DM command to be executed in the DM message, an MO ID of the MO related to the specific node to which the DM command is to be applied, and transmits the DM message through the broadcasting transmission port Broadcast. At this time, the DM message includes node MO position information which is position information of the specific node in the related MO.

The MO ID informs the reference location 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 to identify a root node of the MO corresponding to the MO ID in the DM tree ) Can be grasped. The location of the root node and the node location information can be used to determine the complete location of the node to which the DM command in the DM message will be applied.

The wireless communication terminals 130, 140 and 150 are terminals for performing various wireless communications, and each includes a device management client 131. The DM client 131 communicates with the first DM server 110 via the DM protocol and manages the wireless communication terminal by transmitting and receiving information necessary for managing the wireless communication terminal with the first DM server 110. [ The DM client 131 determines the location of a node to which the DM command included in the DM message is to be applied by using the MO ID included in the DM message transmitted through the broadcasting transmission port channel according to the present invention, Execute the DM command included in the message.

The operation of the first DM server 110 and the first DM client 131 is shown in FIG.

Referring to FIG. 3, in step 201, the first DM server 110 transmits the DM command to be performed according to the present invention, the MO ID of the MO related to the specific node to which the DM command is to be executed, Lt; RTI ID = 0.0 > DM < / RTI >

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

According to an embodiment of the present invention, when the MO message ID is included in the DM message as the reference location information, the MO ID is specified as separate information from the local URI. The node MO location information, which is the location information in the corresponding MO of the node to execute 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 the relative URI. At this time, the relative URI can 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 the Reporting Condition / Frequency to 1 for a specific diagnostic function indicated by the Diagnostics MO and to execute the 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, and this case 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> < ReligI > 1 / DiagMonConfig / ReportCondition / Frequency </ RelURI > </ Source>
<Data> 1 <Data>
</ Replace>
<Exec>
-
<Target> < RelURI > / 1 / Operation / Start < RelURI > </ Source>
<Exec>

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

Upon receipt of the broadcast DM message in step 205, the first DM client 131 detects the MO ID included in the DM message in step 207 as the wireless communication terminal 130 or 140 or 150 receives the broadcast. In step 209, the first DM client 131 determines the position of the root node of the MO corresponding to the MO ID in the DM tree of the wireless communication terminal (130 or 140 or 150) to which the first DM client 131 is attached, &Lt; / RTI > is completed. In step 213, the DM command included in the DM message is executed in the node located in the final local URI. And reports the execution result to the first DM server 110 according to the request or the basic setting of the first DM server 110.

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

<-! Omit unrelated 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 location of the root node 401 of the Diagnostics MO indicated by 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 unrelated 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, MO corresponding to MO ID "urn: oma: mo: oma-diagmon: 1.0" is Diag MO, which is the same MO as "Diagnostics" in 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".

Accordingly, the first DM client 131 receiving the DM message as shown in Table 2 or Table 3 can determine whether the position of the DiagMon MO exists in the DM tree of the wireless communication terminal, And then sets the value of Frequency (403 EH to 503) to 1 in the same manner, and then performs a Start operation (405 or 505) of the corresponding DiagMon MO.

According to another embodiment of the present invention, the MO ID in the DM message may be included as a part of the local URI. This is shown in Table 6. The DM command contents of the DM message shown in Table 6 are the same as those 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 at the beginning of the local URI of the target URI. Upon receipt of the MO ID, the first DM client 131 recognizes the position of the root node of the corresponding MO by confirming that the MO ID is located in the local URI part. Then, by combining the position of the identified root node with the local URI, the DM message is interpreted by reinterpreting it according to its own. The results of the analysis can be shown in Table 4 or Table 5.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments but should be determined by the equivalents of the claims and the claims.
