The example that so is predetermined then can be: i) according to the relevance of two MPs, described MPs will use the described EDCA parameter sets of the described MPs of the QoS policy with tool identity, (that is, in the ECDA parameter sets between the QoS ACs, have maximum distinctiveness person); Ii) according to the relevance of two MPs, described MPs will use the described EDCA parameter sets of activated described MP at most; Iii) according to two MPs relevances, described MPs will use the described EDCA parameter sets of the most described MP of approaching inlet; And iv) according to the relevance of two MPs, described MPs will use the described EDCA parameter sets of the MP that supports maximum traffic (traffic) or similar situation.
2) be relevant to the information of the resource that a MP distributed.Measurement can be used to express the time quantum that the example system of the resource of having distributed includes, but not limited to distribute, packets of information quantity, and byte quantity, Business Stream (traffic streams) quantity, channel utilization index, AC cushions occupancy volume, or the fellow.Each AC can provide this all information.
3) be relevant to the information of the employed resource of a MP.The example that measurement can be used to express the resource of having used includes, but not limited to the delivery time, the passage occupancy volume, and the packets of information quantity that has transmitted, the byte quantity that has transmitted, Business Stream quantity, channel utilization index, AC cushions occupancy volume, or the fellow.Each AC can provide this all information.
4) MP sends (that is, backhaul), the quality that is experienced during binding forward each time at it.The example system that measurement can be used to express the quality that MP experiences includes, but not limited to time jitter (timejitter), time delay, packets of information error rate, defeated inertia (throughput), Queue time (queuedtime), or fellow.
5) for described mesh network for external coexistence IEEE 802.11e client access wireless interface in employed described QoS policy (for example, EDCA parameter sets).
6) employed described QoS policy (for example, EDCA parameter sets) on the described IEEE 802.11e client wireless interface of netted APs.
The execution that described signal sends, can by, but be not limited to:
1) makes described MPs utilize management frames or control frame or be used as the load of Frame and the higher layer information that transmits, and see through described wireless medium and broadcast this information.
2) make MPs directly from requiring QoS information each other.This is can utilize management frames or control frame or utilize the higher layer information that is used as the load of Frame and transmits and reached.
3) make each MP with its QoS information storage in the position among the center DB on the server, and make it can be associated with the QoS information of any MP from described center DB inquiry.
4) make described MPs report this information, and make described CC that this information branch journey is passed to described MPs a central controller (CC).The decision system that described MPs facilitates described CC to send described information includes, but not limited to described MPs and requires information to described CC; Described CC sends described information to all MPs; And the information that described CC only will be relevant to the MPs in a set zone is sent to the described MPs that shares described wireless medium in described regional extent.This is can be by making described MP be reached to described report that described MP can listen to (postponing on critical value (deferring threshold) at it).
Fig. 1 system illustrates according to the utility model, comprises a plurality of mesh point (MPs) 105,110,115, one center DB 120 one, and the different executive modes that signal sends in the mesh network 100 of a CC 125.How Fig. 1 system illustrates QoS information at described MPs 105,110, share between 115 and exchange, this then is can be by described MPs 105,110,115 send to each other packets of information and are finished or it is can see through described center DB 120 or described CC 125 and finished.
Among one first execution mode, one of them of described MPs, MP 105, are with the MPs 110,115 (step 130,135) of its QoS information broadcast to other, and their each can be in order with described QoS information storage among a memory (not shown).
Among one second execution mode, described MPs wherein one, MP 105, system can be to other MPs110, and 115 require QoS information (step 140,150), each of described other MPs then be can be in order with their QoS information (step 145,155) in response.
Among one the 3rd execution mode, described MPs one of them is (for example at least, MP 105) be can be to described center DB 120 its QoS information (step 160) of report, described center DB then is can be with described MP QoS information storage among a memory (not shown), and as a MP, MP 110, require relevant another MP, MP 105, QoS information the time, described center DB 120 will be sent to MP 110 (step 170) with the QoS information of MP 105.
Among one the 4th execution mode, described MPs one of them is (for example at least, MP 105) be the QoS information 175 (step 175) that can be associated with described MP to described CC 125 reports, described CC can report described MP QoS information to the secondary set of all MP or described MPs 105,110,115 in regular turn, with as one broadcasting or the response from described MPs 105,110,115 wherein one one require (step 180,185).
In one embodiment, QoS policy system can only with among the mesh network of other MPs coexistence define and upgrades at a MP, one MP system can receive QoS information from MP miscellaneous (can be from identical mesh network person or from different mesh network persons), and the utility model system allows described MP to upgrade its QoS policy that is had and QoS information with the described netted QoS information that is received as the basis.
Fig. 2 system illustrates according to an embodiment of the present utility model, and this embodiment is in one in narration to comprise a plurality of MPs, and MP 205, and MP 210, and MP 215, one center DB 220, and the situation among the mesh network 200 of a CC 225.
In one first executive mode, netted QoS information 230,235 be can utilize in Fig. 1 illustrational described signal of institute to send to exchange wherein one (that is, the executive mode 1 or 2 of Fig. 1) and from described MPs 205, each of 210 is sent to described MP 215, and described MP 215 can upgrade (that is, adapt to) netted QoS policy and QoS information (step 240) that it had as the basis with the described netted QoS information that is received.
In one second executive mode, described MP 215 be can utilize that the illustrational described signal of institute sends in Fig. 1 (that is, the manner of execution 1,2 or 3 of Fig. 1) and from described MP 205, described MP 210, and the described QoS information 245 of described center DB 220 acquistions, 250,255, and, can upgrade as the basis with the described netted QoS information that is received (that is, adaptation) it had netted QoS policy and QoS information (step 260), then, described MP 215 can be to the described new QoS information (step 265) of described center DB 220 reports.
In one the 3rd executive mode, described MP 215 be can utilize that the illustrational described signal of institute sends in Fig. 1 (that is, the manner of execution 1 of Fig. 1,2, or 4) and from described MP 205, described MP 210, and the described QoS information 270 of described CC 225 acquistions, 275,280, at this, answer described being noted that, described MP 215 can be attached to the QoS information of being transmitted by described MP 205 and described MP 210 described netted QoS more on the new demand 285, then, described CC 225 will upgrade QoS policy and QoS information (step 290), and, it should respond described MP215 by the described netted QoS updating record 295 of which QoS information and QoS policy that will use then can to indicate described MP 215 by meeting, moreover described netted QoS adapts to 240,260,290 is to cook up the operation of analyzing described various netted QoS information, and what determine that described MP 215 will defer to is which.
Described netted QoS adapt to system can utilize a distributed mode and carried out (as the manner of execution in Fig. 21 and manner of execution 2 shown), this then is not need extra signal to send, in addition, described netted QoS adaptation can also utilize a centralized mode and be finished (seeing through the CC 225 in the manner of execution 3 of Fig. 2).
Described netted QoS adapts to operation, and is illustrational as institute in Fig. 3, and the method system of its execution can have several.For example, it is to be received from described mesh network 205 to all, each AC special parameter of 210 described netted QoS information (that is, the parameter of described definition EDCA operation, for example, minimum idle delay (AIFSN) before contention, minimum and maximum contention window (contentionwindows, CWs) (CWmin and CWmax), and TXOP limiting parameter) considers, described various AC characteristics are sorted, select the parameter of the MP QoS that is suitable for a satisfied particular demands most then.
Fig. 4 system illustrates according to of the present utility model one another embodiment, the communication definitions that a mesh network can be disposed in the position that has an IEEE 802.11e network 400.Described IEEE802.11e network 400 is to comprise an IEEE 802.11e AP 405, one MP 410, one center DB 415, an and CC 420, wherein, described MP 410 is can be network coexisted with the outer IEEE 802.11e of described mesh network, if but this coexistence under the situation of not coordinating, then be to cause two kinds of internetwork QoS competitions.It is a hypothesis, one frequency selects the calculation formula at first can carry out computing, operate among identical channel to avoid (as much as possible) described mesh network and described IEEE 802.11e network 400, yet, when described network must be shared identical radio and identical passage, this situation still may take place.
Among described IEEE 802.11e network 400, described MP 410 is IEEE 802.11e beacon (the beacons) (step 425 that can receive from described AP 405,435,450), then, described MP can capture the described IEEE 802.11e QoS information that transmits on described beacon, and, also carry out a regional netted QoS and adapt to (step 430 and 440), and QoS information can utilize a center DB to exchange and the mesh network shared among, 410 of MP can utilize described new QoS information to upgrade described center DB (step 445), moreover, can utilize in the QoS adaptation among the network of centralized system execution, MP 410 can send a netted QoS more new demand 455 to described CC 420, and while additional described 802.11e QoS information in described information 445, then, described CC 420 can carry out described QoS and adapt to (step 460), and a netted QoS updating record is sent to described MP 410, it then is that needs are considered described exterior I EEE802.11e QoS information among described netted scope that described netted QoS adapts to.
One application of rules is in making described and netted relevant QoS information aim at described IEEE 802.11e QoS policy, or minimize a possible QoS conflict at least, but opposite situation (that is, make described IEEE802.11e QoS aim at described netted QoS) but be impossible, because described IEEE 802.11e QoS also can't monitor described MP passage.
The example of the QoS regulation rule that one MP can defer to then comprises, but be not limited to, use have identity between described mesh network and the described IEEE 802.11e QoS information most the QoS policy (for example, the EDCA parameter sets) (that is, has maximum distinctiveness person in the EDCA parameter sets between QoS ACs), definition has the netted EDCA parameter of preferable or relatively poor policy to same AC, helping described netted or described IEEE 802.11e network, or the fellow.
No matter when described MP makes decision and revises described netted EDCA parameter sets, it all must and be transmitted to the remainder of described network with it by the signal transmission, to allow QoS information in a mesh network, to exchange, just as described earlier the same.
In addition, in another embodiment, a MP can coexist with IEEE 802.11e MAPs.Just as discussed previously, MPs system can be connected to netted backhaul and client access interface both, MAPs can have one or more physical radio electricity (physical radios), device for multi radio, one frequency separation of two interfaces is can be by giving them with different channel allocations simply and being reached, yet, example for single radio, even sometimes for a plurality of radio, two interfaces but can use identical radio channel, in the case, will need cooperating to a certain degree of QoS policy between two interfaces, in identical radio channel, to have a coherent system (coherent system).
In order to reach the coherent system that all to support the different QoS policy at backhaul and client access interface on both, described netted backhaul then is the institutional framework (setup) that can need two kinds of set of parameter, by finishing a congenital framework (a priori configuration) (for example, systemic presupposition framework) or by when setting up described system or dynamically seeing through system operation, between different nodes, diffusing information.As for the method that described information exchanges and disperses, then be to use the signal that allows QoS information in a mesh network, to exchange to send planning.
The utility model system provide a kind of at MAPs backhaul and the client access interface between the method that defines in phase and regulate the QoS policy.
Among its simplest form, described identical parameter is to be used to two interfaces simultaneously, so that the professional access of similar information bag (traffic access) is identical, this scenario system can followingly give an example:
ACs priority reflection (ACs priority mapping) is to be shown in the table 1:
| Priority | Netted backhaul ACs | |
|
| 1 | | AC1 | |
| 2 | | AC2 | |
| 3 | Mesh_AC3 | AC3 | |
| 4 | Mesh_AC4 | AC4 |
Table 1
Therefore, when setting up described system or dynamically during system operation, described client access interface will duplicate identical parameter aspect it, for example, and by on described beacon, highlighting them.
In the form of a more accurate complexity, then be some the professional differences that to carry out between backhaul and access side.For example, when business just across described netted and when its only just in the described client access side of access the time, ACs can distinguish.
Above-mentioned in order to reach, the method that can adopt is a lot.A method is, backhaul and client access have different EDCA parameter sets, or channel access parameter set, so that across the packets of information of described mesh network can with distinguish to some extent from packets of information just at the identical AC of the described access path of access, reaching other possibility of this service area then can be, with some mappings (map) among 4 ACs that both deposited to described backhaul, and but some reflections are to described family end access business, in addition, similarly, owing to ACs is professional for the client access is to define by IEEE 802.11e just originally, therefore, another kind of possibility just can be, define more a plurality of ACs (that is, on 4 IEEE 802.11e ACs that both deposited), to control described backhaul business especially.Another kind method is, for described netted inside and outside business provide different TXOP parameters, another kind of again method is, for described netted inside and outside business provide different minimum and maximum contention window (CWmin and CWmax), another kind of again method then is, for described netted inside and outside business provide different interFrameGap (inter-frame spacing, IFS) parameters.
For example, backhaul and client access have different ACs makes that can defer to different business distinguishes strategy, for example:
Staggered ACs priority system is shown in table 2:
| Priority | Netted backhaul ACs | |
| 1 | | |
| 2 | | |
| 3 | Mesh_AC2 | |
| 4 | | |
| 5 | Mesh_AC3 | |
| 6 | AC3 | |
| 7 | Mesh_AC4 | |
| 8 | AC4 |

Table 5
It also might be other combination.
Notably be that the basis of these examples is that 4 ACs are hypothesis of being carried out on described backhaul side.Selecting 4 ACs is a kind of example, also might be the ACs of any other quantity.For example, system can carry out 8 ACs on described netted side, this then is can be so that further difference to some extent of business, for example, according to the quantity of the jump of passing through described network (hops), according to technical specification, or fellow, and make the business of identical category distinguish, similarly, an independent AC system can be in order to binding (bundle) all professional kenels across described backhaul.
Though feature of the present utility model and assembly are to narrate with the preferred embodiment of special combination, but each feature or assembly can use under the situation of further feature that does not need described preferred embodiment and assembly individually, or in conjunction with or do not use under the situation in conjunction with further feature of the present utility model and assembly.
When the utility model is narrated with preferred embodiment, for the person skilled in the art, after dropping in the claim other variation in listed the utility model scope also apparent.
