Background technology
IP multicast is a kind of based on single to many, multipair multimode Real-time Communication Technology in the network of IP agreement, comprise IP multicast group address, a multicast distribution tree and receiver-initiated tree, wherein, sender and recipient use an IP multicast group address to send and receipt message.Multicast group address is filled in the IP destination address field (DAF) of data message by sender, and this address is then sent to network side by recipient, represents that this recipient will receive the message of this multicast group.
Such as, be carried at by data content in multicast group address 239.1.1.1 and send, so sender will send packet to multicast group address 239.1.1.1; Then send and receive messages to network side the interested recipient of data content that sender sends, contain multicast group address information 239.1.1.1 in this receipt message, this multicast group, when receiving receipt message, is sent to recipient by network side.Generally, recipient's informing network side self adds the agreement of multicast group, and advice method the most frequently used is at present IGMP(Internet GroupManagement Protocol, Group Management Protocol).
Because the utilance of IP multicast to the network equipment is high, even if recipient is numerous, sender only needs to send once, only carrys out decision-making by the node (normally switch or router) on network and how to forward and make each recipient can receive IP multicast message.
At present, radio reception device AP uses the mode of broadcast to issue the IP multicast message received, and the mode of AP broadcast group broadcast message specifically can be divided into following several situation:
1. all receiving equipments are not in resting state, and AP then directly adopts the mode of broadcast that multicast message is sent to receiving equipment.
2. receive the receiving equipment existing in this IP multicast group and be in resting state, AP is this multicast message of buffer memory then, sends until send DTIM message next time.
3. receive this IP multicast group and there is the receiving equipment being in resting state outward, AP also needs this multicast message of buffer memory, sends until send DTIM message next time.
All can cause the forward delay interval of IP multicast message for above-mentioned situation 2 and situation 3, affect the service quality of multicast.Especially above-mentioned situation 3, because AP does not specifically distinguish the receiving equipment inside and outside multicast group, therefore in order to ensure that all STA can receive this multicast message, if AP determine to exist the receiving equipment being in resting state will be deferred to send DTIM message next time after send multicast message.But this multicast message is nonsensical to the receiving equipment outside this multicast group in fact, because there is dormancy receiving equipment outside multicast group, the mode of delayed delivery multicast message will cause the consumption that there is no need like this, wherein, reference interval time that DTIM message sends is 300ms, also just means that transmission IP multicast message may postpone 300ms.
