Description

M312845 IX. Creation Description: The technical field to which the creation belongs is related to a wireless communication system, and more particularly, the creation is related to a definition for allowing QoS information to be shared and Q〇S policy to be defined. Mesh application media access control (MAC) layer quality of service (QoS) enhancement. The prior art Wireless Local Area Network (WLAN) system was originally designed to provide best_eff〇rt services to ensure access to the wireless medium between all users. Fairness, this means that in the past, it has rarely been considered to provide a means by which q〇s can be borrowed to obtain a guarantee, or the difference in Q〇S demand between each user can be considered, but with Standardization entities have been formed for the use of WLAN systems to support QoS-driven applications such as voice over Internet protocol (VoIP) and real-time video applications grew. ), for example, IEEE 802.lie, to satisfy this problem. In addition, WLAN networks are gradually evolving to introduce a wireless backhaul connection between access points (APs) in a mesh form, and the benefits of this mesh architecture The trick is to provide low cost, easy to use, and quick deployment. Therefore, M312845 9& 11 ο 3 years · month and day repairs are also added

It is expected that the mesh network will face the same QoS requirements as other WLAN systems. Creative content This creation is a mesh network, which includes multiple mesh points (hereinafter referred to as mps), a central database (database, hereinafter referred to as DB) and a central controller (centrai contr〇iier, Hereinafter referred to as CC)', wherein the mps are constructed to broadcast quality of service (QoS) information on a wireless medium, and each of the suspects can request Q〇s information directly from at least one of the other MPs. And the elbows store the QoSA information in the central DB and construct it to ask the central DB for information about any of the Mps. Therefore, the Q〇s poor news will be in a shareable state throughout the mesh network, and (10) the policy will be defined and updated. One system can coexist with another MP, and the MP system can The system outside the mesh network coexists, and the MP system can coexist with the mesh access point (mesh fine her, brain ^). BEST MODE FOR CARRYING OUT THE INVENTION The preferred embodiments will be described with reference to the drawings, in which the same elements of the same age represent copper. After that, the workstations (also coffee) are used exclusively, including, but not limited to, a wireless transmitting/receiving unit (wireless transmit/receive unit? WTRTT ^ 丄IVU J 'a Zhan Tian Ben, 7 M312845 _,, called - Mobile workstations, - fixed or mobile subscriber units, - call benefits, or other types of devices that can operate in a wireless environment. As mentioned later, an AP includes, but is not limited to, a Node B, - Base station, - location control, or any other device that can be interfaced in a wireless environment. As mentioned later, the proper noun "post network (five) ship (four)), that is, not on the network Wireless interfacing between points (MPS), and vice versa, "professional noun client access" means that an AP and a client workstation (also known as a Basic Service Set (BSS)) Inter-interface. Although the IEEE 802.lle and ffiEE 8〇211 standard groups and files will be used as a reference, this creation can be used for any mesh architecture that supports the Q〇S policy. The features of the present invention can be incorporated into an integrated circuit (IC) or constructed in a circuit that includes a plurality of interconnecting members. IEEE 802.11e standardized one-click priority allocation qoS mechanism is called enhanced distributed channel access (EDCA), which is to specify the required mechanism and signal transmission, and thereby, The AP and its associated client STAs can exchange information about the user's application requirements and the AP's ability to allocate the required radio resources to the STA. The wireless medium can share between most MPs, APs, and STAs. Among the networks, the most advanced technology currently leads to two important issues: M312845 1) The lack of coherence between the Q〇S policies used in the wireless network of the back-end network. The relationship between a standard AP and its STAs can be regarded as a master-slave relationship (master and slave) when the associated APs use the existing priority policy, and by definition, a mesh network The road will also have multiple MPs sharing the same wireless medium, so in such a system, the relationship between 'MPs will be closer to the equal status--and this is open. No (5) Hall can be A destructive model that exploits different priority policies and therefore the possibility of competing for radio resources. 2) The q〇s policy used in the back-end network and the lack of inertia between the client's access to the wireless network interface. The fine-brid network (the MPs talks with the father) and the client's wireless interface (a client STA and a communication) can coexist in the phased pure towel, while the back-end network and the client access both The fact that you can operate on a marriage is to open up two layers to compete for the radio resource in a destructive mode, replacing a constructive mode. In an embodiment, the execution of the sending signal is such that the QoS information can be exchanged in the network packet, and the QoS information shared by the method is included, but is not limited to: 1) used by the MP The QoS construction parameters. For example, in a CSMA plan, this system can reproduce different sets of EDCA parameters, or a set of channel access parameters for each (10) level ((10) class) when the MP competes for the shared media. Similar to the ffiEE 8〇2 iie access category (AeeeSS CategOTies, Ac), the ACs can be defined by a mesh network (eg 'Mesh-AC1, Shih 2, M312845

Mesh-AC3, Mesh-AC4), and its system can assume that the mapping of the same type will be used for the IEEE 802·1 d priority flag (user priority (UP)) And the mapping between the mesh ACs, and further, the parameters defining the EDCA QoS policy, for example, the minimum idle delay for contention (arbitration interframe space number (AIFSN)) , and the minimum and maximum contention windows (CWs) (CWmin and CWmax), and the transmission opportunity (TXOP) limit parameters are in the range of one, which can be different for each AC. In addition, the information may include, but is not limited to, an approval policy that is supported in the mesh network, and a pre-determined rule that allows two or more different MPs to synchronize their QoS policies. . Such a pre-determined instance would be: i) based on the association of the two MPSs, the MPs will use the set of EDCA parameters of the MPs with the most recognizable qos policy (ie, in The largest difference in the ECDA parameter set between qos ACs); ii) according to the correlation of the two, the MPs will use the EDCA parameter set of the mp that has been activated for the longest time; iii) According to the two MPs Sex, the Mps will use the set of EDCA parameters closest to the MP of the entry; and iv) based on the association of the two MPs, the MPs will use MPs that support the largest traffic, or the like. The set of EDCA parameters. 2) Information about the resources allocated by an MP. Examples of measurements that can be used to express allocated resources include, but are not limited to, allocated time 10 M312845 units 'packet number 1' byte number, traffic streams number 'channel utilization, AC buffer occupancy Quantity, or similar. Each AC can be long and has all this information. 3) Information about the resources used by an mp. Examples of measurements that can be used to express resources that have been used include, but are not limited to, delivery time, perpetual traffic, number of packets transmitted, number of bytes transmitted, number of service units, and utilization. , Ac buffer occupancy, or the like. Every AC can provide all this information. 4) The quality of an MP's experience in each of its forward delivery (ie, post-network). Examples of measurements that can be used to express the quality experienced by an MP include, but are not limited to, time jitter, time delay, packet error rate, input inertia (thr〇ughput), queued time (queued time), or Similar. 5) The q〇s policy used in accessing the wireless interface (for example, the edca parameter set) for externally coexisting ieee g〇2.11e clients* for the mesh network. 6) The QoS policy (eg, EDCA parameter set) used on the EE8〇2Jle client wireless interface of the mesh APs. The execution of the number transmission may be by, but not limited to: 1) causing the MPs to use the management φ贞, or control the duck, or the higher layer information transmitted as the load of the number: The media broadcasts this information. 11 M312845 tib. 11. Ο 3 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ This can be achieved by managing the building, or by controlling it, or by using higher-level information that is transmitted by the load of _. 3) Let each MP store its Q〇S information in a central DB located on a server and enable it to query the central DB for QoS information associated with any MP. 4) cause the MPs to report this information to a central controller (cc) and have the CC pass the information to the MPs. The decision that the MPs cause the CC to send the information includes, but is not limited to, the #request to the cc request information; the cc sends the information to all purchases; and the cc will only be related to the information of the MPS in the given area Sended to the MPS that drenched the wireless media within the area. This can be achieved by causing the encounter to report to the MP (which is above its delay threshold). Figure 1 is an illustration of the creation of a mesh network 1 (H) towel, including a plurality of mesh points (MPs) 105, 110, 115, - a central DB 12 根据, and a cc 125 according to the present creation. Different implementation methods. The third diagram is an example of how QoS information can be shared and exchanged between the s1〇5, 11〇, 115, and this can be sent by the offices 1〇5,11〇, 115 The completion of the packaging of each other, or the completion of the system through the central DB 120, or the CC 125. In a first embodiment, one of the classes, ι〇5' broadcasts its q〇s information to other purchases, (out of step 12 M312845 130 '135) and each of them is The QoS information is sequentially stored in a suffix (not shown). In a second embodiment, one of the MPs, the MP 105' will request Q〇s information to the other MRs 11, 115 (steps 14〇, 150) and "Hai other MPs One will respond in turn with their q〇s information (steps 145, 155). In a third embodiment, at least one of the MPs (eg, '105) will report its Q〇s information to the central DB 120 (step 16〇) and the central DB will The mpqoS information is stored in a memory (not shown). When a ΜΡ 〇 〇 〇 〇 〇 〇 〇 要求 要求 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The Q〇S information is sent to mp11〇 (step 17〇). In a fourth embodiment, at least one of the devices (eg, 'biliary 105) reports the QoS information 175/step 175 associated with the MP to the CC 125, and the CC is Reporting the touch (10) information to all Mp, or the MP-pairs of the MPs 1G5, 11G, 115, in sequence, as a broadcast, or a response from one of the MPs 105, 11〇, n5 Requirements (steps 180, 185). In one embodiment, the 'Q0S policy system will be defined and updated in a mesh network that only coexists with other Nen 5 networks. The system can be from a variety of MPs (can be from the same The mesh network, or from a different mesh network) receives the Qos information. This creation allows the suspected = the received mesh qgS information to update its Q〇s policy and Q. 〇s information. 13 M312845 曰 Figure 2 illustrates an embodiment of the present invention, which is described in the _ including a plurality of Mps, a secret, and a Mp central DB 220 'and a cc 225 mesh The situation in the network 200. In the implementation mode of the younger brother, the mesh information is 23〇, and the 235 system uses one of the signals transmitted and exchanged by the ship in the first U-zone (that is, the execution mode of the first figure 1, or 2) Each of the MPs 205, 11() is sent to the MP 215, and the μρ 215 is updated based on the received _ big Q 〇 S information (also #, ize) /, Have a network Q〇S policy and Q〇s information (step 骂). In a second execution mode, the MP 215 will use the signal transmission illustrated in the i-th figure (that is, the execution method of the f 1 picture, or 2) from the [v] P2〇5, the reading 21〇, and the central (10) learned the (^S information 245, 25〇, 255, and will be updated based on the received mesh Q〇s information (ie, adapted) The mesh QoS policy and QOS information (step 26〇) owned by the MP, and then the MP reports the new Q〇s information to the central DB 220 (step 265). Among the execution modes, the MP 215 The signal transmission (ie, the execution method i, 2, or 4 of the second figure) illustrated in FIG. 1 is utilized from the side 205, and the CC 225 acquires the QoS information. 270, 275, 280, here, it should be noted that the MP215 can attach the q〇s information transmitted by the touch 2〇5 and the touch>21〇 to the mesh QoS update request 285. Then, the cc 225 will update the QoS policy and QoS information (step 290), and then 14 M312845 11. 〇3 will indicate the 藉 by 215 Which q〇s information should be used and a mesh Q〇s update report 295 of the QoS policy should be 215. In addition, the mesh QoS adaptation 240, 260, 290 system will plan to analyze the various types. The operation of the mesh QoS information, and determines which one to follow _215. The mesh QoS adaptation system can be implemented in a decentralized manner (as in the execution method and execution method in FIG. 2) 2 shows the same), and this does not require additional signal transmission. In addition, the mesh QoS adaptation can also be done in a centralized manner (through the CC225 in Execution Method 3 in Figure 2). The mesh QoS adaptation operation, as exemplified in Figure 3, can be performed in several ways. For example, it can be received from all of the mesh networks 205, 210. Each AC special parameter of the mesh information (ie, the definition of £1) (:^ operation parameters, for example, minimum idle delay before contention (AIFSN), minimum and maximum contention windows (contention windows, CWs) (CWmin CWmax), as well as the TXOP limit parameter, are considered, sorting the various ac characteristics, and then selecting the parameters that are most suitable for satisfying a specific requirement of Mp Q〇s. Figure 4 is an illustration of another In an embodiment, a mesh network may define a communication that is deployed at a location where a positive EE 802.11e network 400 already exists. The IEEE 802.11 e network 400 includes an IEEE 802.11eAP 405, an MP 410, a a central DB 415, and a CC 420, wherein the MP 410 system can coexist with the ieee 8〇2.11e network outside the mesh network 'but this coexistence if there is no coordination 15 M312845

A rule is adapted to align the mesh-related Q〇s information with the I EE 802.11e qos policy, or at least to minimize a possible (10) conflict, but the opposite case (ie, to make the IEEE 802.11 It is impossible for e Q〇S to align with the mesh Q〇S) because the IEEE 802.11e QoS cannot monitor the MP channel. ^ : Worker 16 M312845 Rev. 3 Correction MP can comply with the Q〇s adjustment rules. Examples include, but are not limited to, the most recognizable between the mesh network and the IEEE 802 11eQ〇s information. QoS policies (eg, EDCA parameter sets) (ie, those with the greatest discrepancies in the EDCA parameter set between QoS ACs), defining mesh EDCA parameters that have better or worse policies for the same AC, Conducive to the mesh, or the positive EE 802.lle network, or the like. When is the decision to modify and adjust the mesh parameter set, it must be propagated to the rest of the road by smart transmission to allow QoS information to be exchanged in a mesh network. As previously described. In addition, in another embodiment, a foundation will coexist with ffiEE 8〇2.Mountain M^Ps. Just as the 'Mps system will connect to both the meshed back-end network and the client access interface, MAPS can have - or multiple physical radios, for multi-radio devices, two The interface-small separation can be achieved by simply assigning them to the channel. However, for a single radio example, sometimes even for multiple radios, the two interfaces can be used. Radio channel, in which case there will be some degree of cooperation between the two interfaces (10) to have a coherent system in the same radio channel. In order to achieve support for different (10) policies on both the back-end network and the client access interface, the _new-network is a set of two sets of parameters that will require parameters, # By; _ 17 M312845 II Ο 3 year film correction apriori configuration (for example, system default architecture), 戍 is at different nodes by establishing the system or dynamically operating through the system Spread information. As for the method of exchanging and distributing the information, it is possible to use a signal transmission plan that allows QoS information to be exchanged in a mesh network. This authoring provides a way to coordinately define and adjust the Q〇S policy between the post-network of the MAPs and the client access interface. In its simplest form, the same parameter can be used for both interfaces at the same time, so that the service access of similar packets (traffic this (2)%) is the same, this communication definition table can be exemplified as follows... The ACS Priority _ (Acs priority mapping) surface is shown in Table i: ------------ Priority mesh network client access ACs ACs 1 ~:---- ------ Mesh—AC 1 AC1 ------ 2 Mesh-AC2 AC2 3 Mesh AC3 AC3 4 Mesh-AC4 AC4 ^ —So ' § build material m is entangled during (10) operation, the f The end access mediator needs to copy the relevant parameters in its aspect, for example, by highlighting them on the beacon. In the form of the "more fresh" form, it is possible to perform some business differences between the back-end network and the access side. For example, t, when the business is across 38 M312845 Λ·τ~

=^进^3 When it is only accessing the client access side, the ACS can use a lot of methods to achieve the above. One method is that the post-network and the client access the forest_EDCa parameter set, or the access control join, so that the packet across the ugly can be accessed from the access channel being accessed. _ AC's package has a dragon, and the possibility of achieving this business difference is ok, there will be 4 existing A. Some of the maps are mapped to the back-end network, and some are mapped to the user-accessible service. Similarly, since the ACs are already using the IEEE 802 for client access services. .lle is defined, so one possibility is to define more ACs (that is, on top of the four existing IEEE 802.11e ACs) to specifically control the post-network service. Another method is to provide different TXOP parameters for the internal and external services of the mesh, and another method to provide different minimum and maximum contention windows (CWmin and CWmax) for the internal and external services of the mesh. Yet another method is to provide different inter-frame spacing (n?S) numbers for the internal and external services of the mesh. For example, the post-network and client access have different ACs so that different service differentiation strategies can be followed, such as: Priority Network Rear Network ACs 1 Mesh-AC 1 2
