Problems solved by technology

[0005] This system, while effective, contains one substantial flaw: after sending a multicast "SEARCH" message, the constrained device sending the message must always keep listening for new service announcements and refreshes of those announcements
However, there is currently no mechanism for instructing other devices to periodically send service announcements or service updates

Embodiment Construction

[0011] The present invention relates to sending signals from restricted devices to other devices on the network for the purpose of instructing other devices to send service announcements, refreshes and / or updates on a regular basis. According to one embodiment of the invention and as shown in Figures 1 and 2, the implementation of this system involves adding new media parameters on the existing MX header. For example, when signaled with a conventional MX header that reads "MX=10", other devices in the network understand this instruction to require any new service announcements to be sent within ten seconds using unicast messages. According to one embodiment of the invention, this header can be modified to include additional values ​​related to the interval at which subsequent service announcements should be sent.

[0012] For example and as shown in Figures 1 and 2, when a restricted device 100 enters the network as shown generally at 200, it sends a "SEARCH" message for recei...

Abstract

A system and method for updating and / or refreshing service announcements at regular intervals to a limited device within a network. The limited device sends a signal to the other devices in the network, requesting that refreshments and / or updates be provided at certain intervals. During these intervals, the limited device can enter a sleep mode, preserving battery life. At the end of the interval, the limited device exits the sleep mode and accepts any necessary updates and / or refreshments.

Description

technical field [0001] The present invention generally relates to the field of terminal architectures in networks. In particular, the present invention relates to terminal architectures in networks when implementing the Universal Plug and Play (UPnP) protocol on constrained devices with energy constraints. Background technique [0002] Network architectures such as the Universal Plug and Play (UPnP) system have become increasingly popular in recent years. UPnP networks are used to connect and allow communication between various electronic devices, including but not limited to desktop and laptop computers, portable and cellular phones, computer printers, monitors, stereos, Personal digital assistants, video game devices and other products. When a device is within coverage of such a home network, it can communicate with any other device within the network. This allows various types of information to be shared. [0003] A situation where information is transferred between d...
