Abstract

A BCAST(Broadcast/Multicast) system and a DM(Device Management) method using the same are provided to considerably reduce a load applied on a network and a server and effectively manage clients. A BCAST subscription management unit generates trap conditions and provisioning contents, and transfers them together with subscriber information to a BCAST service distribution/application unit(S10). The BCAST service distribution/application unit transmits the provisioning contents including the trap conditions to at least one or more terminals(S11). The at least one or more terminals perform provisioning(S12). If a provisioning result is abnormal(namely, when the terminals correspond to the trap conditions), they report the provisioning result to the BCAST subscription management unit through an interaction channel(S13,S14). The BCAST subscription management unit generates a scheduling context for caring the terminals in the trap state(S15) and transmits it to the terminals(S16).

The present invention relates to a broadcast / multicast service (BCAST service), and more particularly, to a BCAST system for selectively treating a specific device after performing provisioning, and a device management method using the same.

The broadcast / multicast service (hereinafter referred to as BCAST service) is a service that provides a mobile terminal with over-the-air broadcasting or other additional information, and provides useful information to all users who have subscribed to their services. It includes both a broadcast service and a multicast service provided only to a certain group of users who have subscribed to a specific topic or content in advance.

1 is a block diagram of a conventional BCAST service system.

As shown in FIG. 1, the conventional BCAST service system generates a provisioning content and transmits the provisioning content generated by the BCAST subscription management unit 10 and the BCAST subscription management unit 10 to manage subscriber information through the BCAST channel. BCAST service distribution / application unit 11 and at least one terminal 12 for receiving the provisioning content transmitted from the BCAST service distribution / application unit 11.

The BCAST subscription management unit 10 and the BCAST service distribution / application unit 11 transmit information and signals to each other through internal communication. At this time, the BCAST subscription management unit 10 is operated as a DM server, the BCAST service distribution / application unit 11 is operated as a file deliverer, the terminal is operated as a DM client.

In addition, the BCAST service system is a BCAST distribution system 13 that supports 1: M communication for transmitting provisioning content transmitted from the BCAST service distribution / application unit 11, and between the BCAST subscription management unit 10 and the terminal It further includes an interaction network 14 supporting 1: 1 communication. Preferably, the two elements 13 and 14 are wireless networks or mobile communication networks which do not provide BCAST services.

The conventional device management (DM) method in the BCAST system configured as described above is as follows.

For provisioning through the BACAST channel, the BCAST subscription management unit 10 (DM server) generates the content to be transmitted and transfers the generated content along with the subscriber information to the BCAST service distribution / application unit 11.

The BCAST service distribution / application unit 11 transmits the content to the terminal 12 through the BCAST channel after referring to the subscriber information. In this case, provisioning of content through the BCAST channel is performed through the BCAST distribution system 12 supporting 1: M communication.

Accordingly, the terminal 12 (DM clients) that have successfully received the content transmit an acknowledgment message to the BCAST subscription management unit 10, and the terminals 12 that have failed to receive the communication directly to the BCAST subscription management unit 10. To receive the necessary content.

However, since terminal provisioning through the BCAST channel targets a plurality of clients, it is difficult for a server to manage all clients (terminals). That is, it is difficult for the BCAST subscription / management unit to check the provisioning results of all the terminals one by one, and in particular, when receiving a response from all the terminals, the network and server load is increased.

Accordingly, it is an object of the present invention to provide a BCAST system and a device management method using the same, which can selectively care for a device having an abnormal provisioning result.

In order to achieve the above object, the device management method of the BCAST system according to the present invention, the device management server transmitting the provisioning content and trap conditions to the device management client through the BCAST channel; And transmitting the response signal to the device management server only if the provisioning result matches the trap condition by executing the transmitted provisioning content.

Preferably, the device management server represents a BCAST subscription management unit.

Preferably, the device management client represents a terminal.

Preferably, the response signal is transmitted in a status code using a device management protocol.

In addition, the device management method of the BCAST system includes the steps of generating a scheduling context for treating the device management client that the device management server has sent a response signal; The method may further include transmitting the generated scheduling context to the device management client.

Advantageously, said scheduling context is transmitted over an interaction channel or a BCAST channel.

In order to achieve the above object, the BCAST system according to the present invention generates a trap condition and provisioning content, BCAST subscription management unit for scheduling the appropriate operation according to the provisioning result; A BCAST service distribution / application unit including the trap condition in a provisioning content and transmitting the same through a BCAST channel; At least one terminal for transmitting a response signal to the BCAST subscription management unit only when the provisioning result is abnormal by executing the provisioning content transmitted from the BCAST service distribution / application unit.

Preferably, the response signal is transmitted in a status code using a device management protocol.

The present invention is implemented in a BCAST system. However, the present invention can also be applied to communication systems operating according to other standards. Hereinafter, preferred embodiments of the present invention will be described in detail.

The present invention proposes a method for efficiently managing a client (that meets a trap condition) in which an abnormal provisioning result occurs when performing multiple client provisioning. To this end, the device management (DM) server transmits provisioning content including a trap condition, and the DM client responds to the DM server only when the provisioning result meets the trap condition, and receives the necessary care from the DM server. . Here, the trap indicates that the device management client of the terminal is in a specific state, and in the present invention, a provisioning result is abnormal.

2 is a block diagram of a BCAST service system applied to the present invention.

As shown in FIG. 2, the BCAST service system according to the present invention generates a context and provisioning content defining trap conditions, and schedules an appropriate action according to the provisioning result. And a BCAST service distribution / application unit 101 for transmitting provisioning content including the trap condition through a BCAST channel, and provisioning content from the BCAST service distribution / application unit 101. Thus, the provisioning result includes at least one or more terminals 102 responding to the BCAST subscription management unit 100 only when the provisioning result is abnormal (that meets the trap condition).

In addition, the BCAST service system and the BCAST distribution system 103 that supports 1: M communication to transmit provisioning content transmitted from the BCAST service distribution / application unit 101, 1: 1 communication for bidirectional communication It further includes a supporting interaction network 104. Preferably, the two devices are non-broadcast networks, either wireless networks or mobile communication networks that do not provide BCAST services.

The device management method in the BCAST system according to the present invention configured as described above is as follows.

First, the BCAST subscription management unit 100 generates a trap condition and provisioning content, and transfers it to the BCAST service distribution / application unit 101 together with the subscriber information (S10).

The BACAST service distribution / application unit 101 transmits provisioning content including a trap condition to at least one or more terminals 102 through the BCAST channel using the subscriber information (S11). In this case, UE provisioning through the BCAST channel is performed through the BCAST distribution system 102 supporting 1: M communication.

The at least one terminal 102 receives provisioning content and performs provisioning (S12). If the provisioning result is abnormal (matching the trap condition), that is, the provisioning result is identical to the trap condition included in the provisioning content. If there is a match, the provisioning result (response signal) is reported to the BCAST subscription management unit 100 through an interaction channel (S13, S14).

Preferably, the provisioning result is reported by Generic Alert 1226, which is a status code defined in the DM protocol.

Accordingly, the BCAST subscription management unit 100 transmits the response signal, that is, generates a scheduling context for treating the terminals 102 in the trap state (S15) and then interacts with the channel or the BCAST channel. Through the transmission to each terminal 102 (S16).

Provisioning, on the other hand, can be said to be an initial step to perform a continuous process in the device management technology. Accordingly, as shown in FIG. 4, when bootstrap is performed for the purpose of continuous provisioning, continuous provisioning may not be performed if an abnormal (exceptional) situation occurs. Even in this case, if the trap condition is included in the predetermined bootstrap process and transmitted to the terminal, the terminal in the trap state may actively perform an exception processing.

As described above, the present invention reports the result to the server only the client that the exception occurs when the terminal provisioning through the BACST channel. Thus, the server does not always need to check the client's status, but only schedules appropriate actions when reports come from clients that match the trap conditions. By performing such a series of processes, the present invention can significantly reduce the load of the network and the server compared to the conventional technology, and has the effect of efficiently managing the clients.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
