Embodiment Construction

[0043] The implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] Referring to the communication system shown in Figure 3, it includes a domain controller 30 (DC, Domain Controller), a local domain manager 31 (LM, Local Master) and a plurality of domain member devices 32-34 (not limited to 3 domain member devices ). The domain controller 30 controls the device to join the domain, leave the domain and update the relevant information of the domain; the local domain manager 31 provides services for the domain members in the domain, and the domain member devices interact with the domain controller 30 indirectly through the local domain manager 31 to complete Actions such as joining or leaving a domain. When a domain member device in the domain finds that the local domain manager 31 does not exist, one of the domain member devices 32-34 initiates an election request message, and the reque...

Abstract

The invention discloses a method of selecting a local field manager to solve the problem that a large amount of system resource has been occupied using the local field manager LM in the existing technique. A field member device in the field sends a request message of voting LM, wherein the request message carries over capability information of an initiation device. The other field member devices in the field receiving the request message compare the LM capability of the said device and the said initiation device, when judging that the LM capability of the said device is stronger than the LM capability of the said initiation device, a response message with the said capability information of the said device is sent. The device with the strongest LM capability in the said initiation device and all the field devices for sending the response information sends the message information of vote result to the other field member devices. The invention also discloses a communication device and a communication system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for selecting a local domain manager. Background technique [0002] A domain is a collection of a group of devices. In many content protection systems, the use of content is limited by the domain, that is, devices in the same domain can easily share and use digital content in the domain, such as movies, music, etc., instead of the domain. Devices in the domain cannot access the digital content. Through the domain, it not only prevents uncontrolled arbitrary copying and use of content, but also provides a certain degree of convenience for users to share content. [0003] The most common application of domains is in a home network. Users form their own devices into a domain, so that they can freely use the content in the domain on any device. These devices can be distributed in different geographical locations. For example, a user has a ...
