Title:
サブネットワークによる連続待機時間の改善
Document Type and Number:
Japanese Patent JP2009543476
Kind Code:
A
Abstract:
Broadcast or multicast traffic is classified into different types of traffic such that different types of traffic are transmitted over different sub-networks. In addition, different transmission schedules may be associated with each of the different sub-networks. A device may thus be configured to receive only a selected portion of the different types of traffic by only waking from a power save mode at the intervals at which the corresponding sub-network sends the traffic. The standby time of the wireless station may thus be improved because the wireless station may awaken less frequently and for shorter periods of time. Different sub-networks carrying different types of broadcast and multicast traffic may be implemented in an 802.11-based system. For example, a single access point may define multiple basic service set identifiers for a single wireless channel.
