Broadcasting Transport for Wireless Terminal Device Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device management methods for wireless communication terminals operate on a peer-to-peer basis, making it difficult for service providers to simultaneously control terminal functions according to established policies across multiple devices.
Innovation Solution
A method and system that enables interaction between a BCAST server and a DM server to generate and execute DM commands, allowing for the simultaneous delivery of DM commands to multiple wireless communication terminals using a broadcasting transport, with the ability to add service restrictions such as area and condition information, reducing wireless resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional peer-to-peer device management method is used, then individual terminal control is achieved, but simultaneous control of multiple terminals according to service policy is difficult
Solution Approach 1:
The patent introduces a service provider server as an intermediary between the device management server and multiple terminals. The service provider server receives service policy information from the device management server, generates service guide information based on this policy, and distributes it to terminals. This intermediary structure enables centralized control of multiple terminals according to service policies without requiring complex peer-to-peer management configurations.
2Productivity
If DM commands are delivered to multiple terminals individually, then each terminal can be managed separately, but wireless resource consumption increases
Solution Approach 1:
The patent merges the delivery of management information to multiple terminals by incorporating service policy information into a single service guide that is broadcast to all terminals simultaneously. Instead of sending individual DM commands to each terminal, the service provider server includes the management policy in the service guide information that is distributed to all terminals at once, thereby reducing wireless resource consumption while maintaining management efficiency.
3Reliability
If service restrictions are added to DM commands, then terminal function control is improved, but command complexity increases
Solution Approach 1:
The patent applies service restrictions to service guide information before distribution to terminals. The service provider server receives service policy information containing restriction rules, incorporates these restrictions into the service guide information in advance, and then distributes the prepared information to terminals. This preliminary action ensures reliable service policy enforcement while avoiding the need for complex restriction processing in each terminal.

AI summary
A remote management method for a terminal supporting a mobile broadcast service is provided. The terminal receives a service guide with a terminal function management condition from a mobile broadcast service broadcasting server, stores and processes the service guide, and delivers a service subscription request to the mobile broadcast service broadcasting server, receives a message with a Device Management (DM) command generated by a DM server, as the mobile broadcast service broadcasting server receiving the service subscription request sends a request for a DM command regarding a function and a management operation of a terminal to be managed, to the DM server, and stores the DM command and executes the DM command if a status of the terminal satisfies the terminal function management condition.
