External Service Control for Home Network Device Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network systems require at least one DLNA device with DMC functionality, increasing technical requirements and costs, as they need to support service processing and media services, which complicates operator service dependence and deployment.
Innovation Solution
A method and system where an outside network device provides service control capabilities to DLNA devices within the home network by sending a service request, receiving a DLNA device list and control script, and selecting an appropriate device to execute media services, reducing the need for internal network device configurations and lowering costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If at least one DLNA device with DMC function is set in the home network to support service processing, then service capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces an external service control device as an intermediary between the home network DLNA devices and the operator network. This external device provides the DMC (Digital Media Controller) service control capability remotely, eliminating the need for internal devices to have complex DMC functions. The external service control device receives service requests, generates control scripts, and guides internal devices to execute services, thereby resolving the contradiction between service capability and device complexity.
2Adaptability or versatility
If DLNA devices support service processing and media services, then service functionality is improved, but cost increases
Solution Approach 1:
The patent extracts the service control function from the home network devices and relocates it to an external service control device in the operator network. By taking out the DMC service control capability from internal devices, the patent reduces the technical requirements and costs for manufacturing home network devices while maintaining full service functionality through the external control mechanism.
3Reliability
If home network devices have service control capability, then service independence is improved, but operator service deployment flexibility decreases
Solution Approach 1:
The patent shifts the service control dimension from the home network domain to the operator network domain. Instead of having service control capability distributed across home devices, the control function is moved to the operator's external service control device. This dimensional shift allows operators to centrally manage and flexibly deploy services while home devices maintain operational independence through executed control scripts.

AI summary
A method, an apparatus and a system can be used for implementing service control of a home network device. A first DLNA device sends a service request to a user interface server. The first DLNA device receives a DLNA device list of the home network wherein the first DLNA device is located and a control script corresponding to a media service to be executed that are sent by the user interface server in response to the service request. The first DLNA device selects a second DLNA device from the DLNA device list and controls, according to the control script, the second DLNA device to execute the media service to be executed.
