Abstract

Broadcast or multicast traffic is classified into different types of traffic and different transmission schedules associated with each of the different types of traffic. The different types of broadcast and multicast traffic may be implemented in an 802.11-based system where an access point is configured to classify broadcast and multicast traffic into different types and assign different transmission schedules to each of the different traffic types. An associated wireless station may thereby wake from a power save mode only at intervals corresponding to delivery times of the types of traffic that the wireless station has elected to receive. In some aspects the different types of broadcast and multicast traffic may comprise user plane traffic and control plane traffic.

Embodiment

Each side of the present invention is hereinafter described.Obviously, teaching herein may be embodied in the extensive various ways and any ad hoc structure disclosed herein and/or function only are representational.Teaching based on herein those skilled in the art will appreciate that, one side disclosed herein can be independent of any others and implement and can make up in every way in these aspects both or both more than.The aspect of any number that for instance, can use herein to be stated is implemented a kind of equipment and/or is put into practice a kind of method.In addition, can use except or the aspect that is different from herein to be stated in other one or more structures and/or functionally implement a kind of equipment and/or put into practice a kind of method.

Some aspects of Fig. 1 illustrative system 100, wherein the broadcast or multicast business is classified as dissimilar business.System 100 comprises the network access device 102 of user's set (for example, the accessing terminal) communication that is associated with one or more.For simplicity, will discuss the each side of user's set referring to user's set 104.Come route to go to the business of user's set 104 data of forms such as frame, bag (for example, with) via access device 102.For instance, access device 102 can receive professional via link 106 from wide area network (" WAN ").Perhaps, access device 102 can receive the business of going to user's set 104 from another user's set or a certain other device (not shown).Access device 102 then is forwarded to user's set via link 108 with business.Also user's set can be called subscriber's installation (UE), access terminal, stand (STA), radio communication device, terminal, user terminal, move equipment, subscriber unit or a certain other term.User's set can be cellular phone, smart phone, cordless telephone, laptop computer, PDA, wireless device, radio modem, mobile device, hand-held set, handheld apparatus, satelline radio, global positioning system or a certain other communicator.

For saving power and increase the stand-by time of user's set 104 whereby, user's set 104 can be converted to power save mode when it does not send or receives business.For instance, at least a portion in the assembly of user's set 104 can be switched to halted state or outage at this moment.In the typical case uses, for example lower layer components of receiver 110 (for example, multiple component units) can be switched to halted state with saving power.

User's set 104 wakes up to send or to receive professional from power save mode once in a while.For instance, access device 102 can any one (for example, user's set 104) in user's set cushion the broadcast or multicast business of going to user's set when being in power save mode.In addition, access device 102 can be configured and the business through buffering sent to user's set with time interval of defining.In the case, each user's set is configured and wakes up to receive business from its power save mode with the time interval of defining.

In some applications, given user's set can only need receive the part of broadcast or multicast business.For instance, the broadcast or multicast business can comprise the business of control plane business (for example, ARP is professional or other business relevant with management), user-plane traffic (for example, stream audio or video) and (possibility) a certain other type.Yet in some example, user's set may be lost interest in to receiving user-plane traffic.For instance, the user may not have in order to receive the reservation of broadcast or multicast from given access point.As another example, the user may not want to watch the current video crossfire.Therefore, can make regulation so that user's set can the time remain in power save mode in access device 104 transmission user plane traffic or a certain other non-business of wanting.

In certain aspects, access device 102 can be categorized as different service types with the business of going to user's set.Herein, two or more types of service of access device 102 definition make that access device 102 is categorized as one in the defined type of service with that business when the given professional example of access device 102 receptions.In addition, access device 102 can transmit different service types at different time.Therefore, under user's set 104 did not wish to receive one or more situation in the described dissimilar business, user's set 104 can be chosen in and remain in power save mode when access device 102 transmission are non-wants type professional.

Will be in conjunction with the flow chart of Fig. 2 and further discuss these and other aspect of the present invention in more detail referring to Fig. 1.Fig. 2 A relates to can be through carrying out the broadcast or multicast business is categorized as the operation of different service types.Fig. 2 B relates to can be through carrying out optionally to receive the one or more operation in the described dissimilar broadcast or multicast business.The operation of Fig. 2 (and any other flow chart herein) can be described in conjunction with specific components for simplicity.However, it should be understood that can in conjunction with and/or use other assembly to carry out these operations.

At first, as represented, from the source reception broadcast or multicast business of for example another communicator by the block among Fig. 2 A 202.In the example of Fig. 1, access device 104 can receive the broadcast or multicast business via link 106 from WAN or from a certain other source (not shown).

As represented, the broadcast or multicast business that is received correspondingly is categorized as the type of service of being supported by block 204.For instance, in Fig. 1, professional grader 112 can be categorized as the business that is received one in two types the business.Professional grader 112 and/or associated component then are stored in the business (being designated as one in two kinds of types of service 114 and 116) that is received in the professional buffer 118 when one or more user's sets are in power save mode.

Dissimilar business can be associated with different transmitting and schedulings.For instance, the business of the first kind can be transmitted with the given interval with period demand through scheduling.The business of second type can be transmitted with the different time with different cycles at interval through scheduling.As illustrated in fig. 1, access device 102 can be kept type of service and be used for the transmitting scheduling information that is associated 120 of each type of

service

122 and 124.

As represented, can therefore each type of service be transferred to user's set (or other device) according to the transmitting and scheduling that is associated by block 206.For instance, in Fig. 1, scheduler 126 can be by the transmission of initial Class1 business 114 through cushioning of the time interval that schedule information 122 defines.Similarly, scheduler 126 can be by the transmission of initial type 2 business 116 through cushioning of the time interval that schedule information 124 defines.

Now referring to Fig. 2 B,, can be configured to be received in one or more in the described dissimilar business of the optionally connected receipts of device of business of block 206 places transmission as represented by block 208.In Fig. 1, type of service selector 128 can be determined the type of the business that will be received by user's set 104 under manually or automatic control.Therefore, type of service selector 128 can select only to receive (for example) type of service 2.

As mentioned above, be saving power, device can not transmit or receives ingoing power save mode (or a certain other similar pattern or state) when professional at it.For this reason, user's set 104 comprises the state controller 130 of the mode of operation that is used to control one or more assemblies.For instance, state controller 130 can switch on receiver 110 between awakening mode (for example, normal, active state), power save mode (for example, time-out or resting state) or a certain other pattern.

As represented by block 210, device is converted to awakening mode to receive the business of selection type from power save mode between can be in due course.Can derive the suitable wakeup time that is used for given type of service from the relevant parameter being stored in user's set 104 132 and 134 herein.As an example, to select under the situation of type 2 business at selector 128, state controller 130 can cause receiver 110 so that 134 time intervals of defining were converted to awakening mode at interval by 2 business hours of type.

As represented by block 212, therefore described device can receive the business of selection type.Such as among Fig. 1 displaying, can start receiver 110 and only obtain the business 136 of selection type to receive professional via link 108.In case this business is received, user's set 104 just can turn back to power save mode.Advantageously, user's set 104 need not to wake up with type of receipt 1 business.Therefore, the stand-by time of user's set 104 can be improved, check because can wake up and/or analyze by the more conventional method of all broadcast or multicast business of access device 102 transmission on the contrary that it can remain in power save mode and continue longer period with user's set 104 wherein.

Can implement to relate to equipment or the method that the broadcast or multicast business is categorized as dissimilar business in many ways.For simplicity, now in situation, additional detail is described based on 802.11 system.However, it should be understood that herein teaching be not limited to the system of this type or herein the assembly and the operation of concrete statement.

In based on 802.11 system, the access device 102 of Fig. 1 can comprise access point, and user's set 104 can comprise wireless station.To discuss in these assemblies each in more detail in conjunction with Fig. 3 and Fig. 4.

Fig. 3 illustrates some aspects of access point 300.Access point 300 comprises grader 302, professional buffer 304 and scheduler 306 and other assembly that can be similar to the corresponding assembly among Fig. 1.Concise and to the point, access point 300 comprises from the receiver 308 (upper right portion of Fig. 3) of (for example) network receiving downlink business.Grader 302 is categorized as the business that is received the dissimilar business that is associated with different transmitting and schedulings.When in the station in the service groups of access point any one was in power save mode, access point 300 was stored in the business through classification in the professional buffer 304.Then, based on transmitting and scheduling separately, scheduler 306 is cooperated with transmitter 310 dissimilar business is transferred to the station in the service groups.

Fig. 4 illustrates some aspects at wireless station 400.Stand and 400 comprise receiver 402, type of service selector 404 and state controller 406 and other assembly that can be similar to the corresponding assembly among Fig. 1.Receiver 402 (lower right-most portion of Fig. 4) is suitable for via the business as being transmitted by transmitter 310 by the line 408 represented channels receptions based on 802.11.Based on the selection of being made by selector 404, state controller 406 can cause receiver 402 to wake up to receive the business of selection type from power save mode at interval with appropriate time.

To discuss these and other example operation in more detail in conjunction with the flow chart of Fig. 5, Fig. 6, Fig. 7 and Fig. 8.Fig. 5 relates to can be through carrying out with the various aspects of configuring access point with the operation at the station that is associated.Fig. 6 relates to the each side of the operation that can be carried out by access point.Fig. 7 relates to can be by the each side of station execution with the operation of the business of reception particular type.Fig. 8 relates to the each side that can carry out by standing with the operation that receives dissimilar business.

Referring to Fig. 5, as represented by block 502, when wireless station (" STA ") entered the overlay area of access point (" AP "), described station and described access point can begin associated program (block 504).For instance, assembly is negotiable communicates by letter and/or supports various functional in a certain mode.For this reason, the station 400 of Fig. 4 can be incorporated media access controller 410 into, and described media access controller 410 is suitable for communicating by letter with the access point 300 of Fig. 3 with via based on 802.11 channel and set up communication.Be to reduce the complexity of Fig. 3 and Fig. 4, do not describe other related assembly in this and other routine operation.

As represented by block 506, in conjunction with the program that is associated or At All Other Times a certain, it is interested that the described station of visual advisory access point, wireless station has been classified as dissimilar broadcast or multicast business to reception.In the example of Fig. 3 and Fig. 4, institute's supporting business type identifier assembly 412 of standing in 400 can send to an inquiry access point 300 to determine whether access point 300 supports the business that is classified.

As represented by block 508, access point can be configured to based on as hereinafter one or more standards of more detailed argumentation the broadcast or multicast business is categorized as dissimilar business.Support at access point 300 under the situation of the described business that is classified that access point 300 can be retained in the information relevant with the type of service of being supported 312 and the transmitting and scheduling (for example, time interval information) that is associated 314 in the data storage 316.In some embodiments, can by the system manager statically configuring access point 300 business is classified according to the website demand.

In some cases, 400 (for example, identifier 412) and the access point 300 of standing is negotiable to use dissimilar business and the transmitting and scheduling that is associated.Through consulting thus, stand (for example, identifier 412) can obtain type of service and transmitting scheduling informations from access point 300, and the respective entries relevant with the type of service of being supported 414 and the scheduling that is associated 416 is kept in the data storage 418.

As the replacement scheme of the example of block 506,400 information that can a certain alternate manner dispose about different service types of standing.For instance, access point 300 can implement to define the known classification mechanism of dissimilar business.In the case, 400 place service kind or a certain At All Other Times the time when standing, described station 400 is configurable this classification mechanism.Perhaps, wireless station 400 can be configured to " study " this classification mechanism.

Can business be categorized as number of different types according to the demand of giving fixed system.For instance, mentioned in certain aspects as mentioned, can with one type broadcast or multicast service definition user-plane traffic.This type of business can be including (for example) using the business that is associated, for example stream data, audio or video with the user.This type of business can be derived from (for example) television set or radio broadcasting, server or a certain other source.Therefore user-plane traffic can comprise and business that is associated by content transmitted and/or the business that is associated with related operation in the delivery of content.

Can with the broadcast or multicast service definition of another type the control plane business.This type of business can including (for example) with operation, management or access station in the one or more business that are associated.Usually, the business of this type can adopt the form of Web broadcast business.In certain aspects, the control plane business comprise with the station connectivity, topology, path discovery, address resolution protocol (" ARP "), DHCP (" DHCP "), existence or paging in the one or more business that are associated.An example that exists relates to the inventory that available contact is provided in instant message device is used.

Should be understood that business to be categorized as based on herein teaching and comprise and/or be different from the polytype of the type of service of concrete statement herein.For instance, some station can be only interested in the content that receives some type.Therefore, can business be classified based on the certain content of broadcast or multicast business.Similarly, some station can be only interested in the management service that receives some type.In the case, can business be classified based on sending the dissimilar management service that arrives at a station via the broadcast or multicast business.

In addition, according to the demand of giving fixed system, business can be categorized as the type of any number.That is, business can be categorized as 2 kinds, 3 kinds or more kinds of dissimilar.

And multiple transmitting and scheduling can be associated with the business of each type.Usually, different transmitting and schedulings can be associated with each type.Yet, in some cases, same transmitting and scheduling need be assigned to two or more type.

Can define these transmitting and schedulings in many ways.For instance, in some cases, transmitting and scheduling can define the time interval of the business that repeats to transmit given type.Perhaps, the transmitting and scheduling definable transmits the time scheduling more at random of the business of given type.

Preferably, each transmitting and scheduling is the multiple of one in the described transmitting and scheduling, makes that some transmission in the transmission of different service types will overlap.For instance, the very first time can be associated with the business of the frequent transmission of access point at interval.Any interval At All Other Times of being supported by described access point can then be a very first time multiple at interval.For instance, second time interval can be the very first time two double-lengths at interval, and the 3rd time interval can be the very first time three double-lengths at interval.In addition, can define second time interval and the 3rd time interval, make itself and the very first time overlap at interval.In this way, do not support the old-fashioned station of the different service types under the different transmitting and schedulings to receive all broadcast or multicast business that cushion and transmit by access point at interval by its static wakeup time being set at interval the very first time.

The transmitting and scheduling of the business of given type can be depending on the transmission characteristic of described business.For instance, access point receive the frequency of the business of some type can be greater than the frequency of the business that receives other type.In addition, access point can receive the professional of some type the regular relatively time interval and irregularly serve as the basic business that receives other type.Crossfire business (for example, audio or video broadcasting) is the representative instance of the business of last type.In some applications, the about business of 100ms or littler time interval stream transmission this type.Management service is the representative instance of the business of back one type.The business of this type has sudden in nature usually and is relating generally to the transmission of (on average) more a spot of information.Therefore, access point can be assigned to the relatively short time interval and receive frequently relatively and/or relate to the business that transmits data in time in a large number.On the contrary, access point can receive relatively not too frequently with being assigned to than the long time interval and/or relate to the business that transmits data in time in a small amount.

Once more referring to Fig. 5, as represented, in case the station receives the business information that is classified, just one or more in the type of service that the optionally connected receipts in described station are supported by block 510 and 512.For instance, as represented by the line among Fig. 4 420, type of service selector 404 can insert the traffic type information of being supported 414.One or more in the type of service 414 that type of service selector 404 can then be selected to be supported, and as represented by line 422, this selection information is sent to scheduler component 424.

Type of service selector 404 can be selected automatically based on user's input or with a certain other suitable manner.For instance, standing 400 can comprise user interface 426, and described user interface 426 is suitable for receiving the business that makes the user can select the types that will be received by station 400 from user's input.

Perhaps, selector 404 can be incorporated the study mechanism that makes selector 404 can select type of service automatically into.For instance, selector 404 can comprise the professional traffic analyser of analyzing on the link 430 428 that receives.Traffic analyser 428 can be collected the information that will be used by type of service study module 432 whereby to determine to select the business of which type.As an example, the business on the link 430 can indicate the station to enter the overlay area of known access point.Based on previous study (for example, manual or automatic), the business that some type that is provided by that access point can be provided study module 432 is not the indication of desired business.Therefore, selector 404 can be selected to receive only some business the business of described type (that is, right and wrong are not wanted the business of type) from that access point.

As hereinafter discussing in more detail, service delivery can be transmitted beacon with access point and be associated.For instance, according to traditional based on 802.11 operation, access point regularly the time interval send beacon, each beacon can indicate the broadcast or multicast business whether will follow beacon whereby.Be to support dissimilar as used herein teachings business, given beacon can comprise with described different service types in one or more relevant information.This information can comprise the indication of (for example) beacon type and whether will transmit any business of the type that is associated with the beacon of that type after described beacon.

Therefore, in certain aspects, access point can transmit the beacon of the particular type that is associated with that type of service corresponding to the time interval of the transmitting and scheduling of the business of particular type.In the case, stand and to wake at interval whether definite access point will transmit the business of respective type after beacon to receive beacon up by appropriate time.

Block 510 among Fig. 5 relates to the situation that selector 404 is selected the business of single type.In the case, wireless station 400 can be configured to only wake up and receive the beacon that is associated with the business of that particular type.

Block 512 among Fig. 5 relates to the situation that selector 404 is selected the business of more than one types.In the case, wireless station 400 can be configured to wake up each in each beacon that is associated in the business that receives with described selection type.

Now referring to Fig. 6, with argumentation can be by the selected operation in order to business is classified of access point execution in more detail.As represented by block 602, access point receives the broadcast or multicast business via (for example) network.In the example of Fig. 3, receiver 308 receives this downlink traffic and described business is provided to grader 302.

As represented by block 604, it is professional and described business is categorized as one in the type of service of being supported that grader 302 analysis is received.Discuss as mentioned, the business that is received can be classified as user-plane traffic, control plane is professional or the business of a certain other adequate types.

Grader 302 can be classified business based on one or more standards.For instance, in certain aspects, can business be classified based on the content of business.In the case, grader 302 can comprise the bag detector 318 of the bag content in the analysis business.Bag detector 318 can obtain for example information of protocol information, address information, port information and service type information from the bag 320 that is received.Comparator 322 can then compare described package informatin and the information that is stored in the classifier data storehouse 324.Based on this relatively, grader 302 can be with business (bag) classification that is received.In fact, grader 302 can be determined to make about the final of type of service from given the information in classifier data storehouse 324 independently or in conjunction with out of Memory (for example, from classifier data storehouse 324) use.Some examples that can be stored in the information in the classifier data storehouse 324 are as follows.

The address information 326 in order to the business of identification particular type can be contained in classifier data storehouse 324.For instance, given source address and/or given destination-address can be associated with the business (for example, streamed content, management etc.) of particular type.Advantageously, can in the professional encrypted application that is received, use address information.That is, in general, when the out of Memory (for example, port information and content) in the bag is encrypted, address information will be not encrypted.

The port information 328 in order to the business of identification particular type can be contained in classifier data storehouse 324.For instance, given source port and/or given destination port can be associated with the business (for example, streamed content, management etc.) of particular type.

The protocol information 330 in order to the business of identification particular type can be contained in classifier data storehouse 324.For instance, can use User Datagram Protoco (UDP) (" UDP ") and/or real-time protocol (RTP) (" RTP ") to send the crossfire business.Therefore, when the business support specified protocol 330 that received, grader 302 can be categorized as this business the business (for example, user plane) of particular type.Discuss as mentioned, grader 302 can use this information to determine to make about the final of type of service in conjunction with out of Memory.

COS (" the TOS ") information in order to the business of identification particular type can be contained in classifier data storehouse 324.Can use the specific business of discerning particular type that is provided with of the TOS position in the bag herein.

Perhaps, can business be classified based on other characteristic of business.In certain aspects, grader 302 can keep the record of the received frequency of business of particular type.In the case, traffic frequencies information 334 can be associated with the business of particular type.For instance, can receive the business relevant relatively continually with content, and can be relatively receiving management or control are professional continually.And grader 302 can be determined to make about the final of type of service in conjunction with out of Memory frequency of utilization information 334.For instance, frequency information can be collected to determine the frequency of given traffic streams with address or port information.

In certain aspects, the record 336 about one or more application that are associated with business can be determined and/or keep to grader 302.Herein, application-specific can be associated with the business of one or more particular types.

Can obtain to be used for the standard of sort operation in many ways.For instance, can be based on the known relation between the business of information and particular type with in the manual input category device of the information database 324.On the contrary, the various standards that can use study module 338 dynamically to classify and be associated with the business of particular type.Herein, study module 338 can be analyzed the business that is received, and based on (for example) and the relevant information of previous classification, study module can produce can be in order to the standard with current or following professional classification.

Referring to Fig. 6, any one in the station in the service groups of access point is under the situation of power save mode once more, access point available buffer downlink broadcasting or multicast service (block 606).In the example of Fig. 3, business is stored in the professional buffer 304.Herein, all the professional modes that can easily retrieve given type from professional buffer 304 are stored in

dissimilar business

340 and 342 the professional buffer 304.

In certain aspects, stand and indication positive ingoing power save mode in described station and described station can be sent to access point with the message that only wake up at some type of service.When can advantageously using this information to be in power save mode at described wireless station, described access point selects not cushion the business of some type.For instance, if all the wireless stations that are in power save mode in the service groups of access point have selected to ignore the business of a certain type, then access point can select to transmit immediately described business when broadcast/multi broadcast business is received.In the case, systematic function can be improved owing to having eliminated the delay that originally is awarded owing to buffer traffic.

Under the situation that business is cushioned, as represented by block 608, access point produces corresponding to each the beacon in the type of service of being supported.Discuss as mentioned, beacon can comprise whether identification beacon type and indication access point will be right after the information of transmitting the particular type business after beacon.

Comprise in the example of user-plane traffic and control plane business in the type that is classified, user-plane traffic can be associated with business transferring indicator diagram (" the DTIM ") beacon of routine.Therefore, whether the DTIM beacon can provide will be in the indication after the DTIM beacon about user-plane traffic.

According to convention, can a time interval produce the DTIM beacon, the described time interval is the time interval (for example, multiple 100ms) based on the beacon of standard 802.11 that comprises professional indicator diagram (" TIM ").How to dispose according to access point, the DTIM time interval can be identical with the beacon time interval or be the multiple in the beacon time interval.

In addition, the beacon that is known as the new model of management service indicator diagram (" MTIM ") beacon can be associated with the control plane business.Whether can therefore use the MTIM beacon to provide will be in the indication after the MTIM beacon about the control plane business.

Can a time interval produce the MTIM beacon, the described time interval is the multiple in the beacon time interval and/or the DTIM time interval.In addition, the MTIM time interval can be identical with the beacon time interval and/or the DTIM time interval or be longer than the beacon time interval and/or the DTIM time interval.Usually, the MTIM time interval will be longer than the DTIM time interval, make can be by selective reception control plane business but not the station of user-plane traffic realize stand-by time and increase.

In certain aspects, access point can support a kind of being used for to provide the dynamic approach of arriving at a station with transmitting scheduling information.The information that can comprise for instance, the time interval of specifying the beacon (for example, TIM, DTIM, MTIM etc.) that is used for each type by each beacon of access point transmission.In addition, each beacon can comprise before next beacon that specifies in transmission particular type (for example, DTIM, MTIM etc.) counting with the number of the beacon (for example, conventional beacon) that is transmitted.For instance, when corresponding counts reached zero, this was the indication of DTIM beacon and/or MTIM beacon as current beacon.In this way, only (for example, MTIM) power save mode can be selected to remain in interested station, transmits up to access point till the beacon of that type to the beacon of particular type.

Referring to the example of Fig. 3, beacon generator 344 can produce the Figure 34 6 and 348 corresponding to each beacon type.Discuss as mentioned, the business that Figure 34 6 and 348 can comprise respective type is with the indication after

beacon

350 and 352 and the

information

354 and 356 relevant with the time interval that is used for that beacon or a certain other beacon.

Referring to Fig. 6, therefore access point can transmit various types of beacons (block 610) with the fixed time at interval, transmits the business (block 612) of respective type subsequently once more.Referring to Fig. 3, scheduler 306 can be cooperated with transmitter 310 and be sent beacon and business at interval with reasonable time.For instance, scheduler 306 can be retrieved schedule information 314 to determine when the beacon that sends particular type.Scheduler 306 can then be retrieved respective beacon information (for example, beacon Figure 34 6 or 348) and this information is provided to transmitter 310 and transmits at interval with reasonable time.Similarly, scheduler 306 can be retrieved the business (for example, professional 340 or 342) of suitable type and this information is provided to transmitter 310 and transmits after respective beacon.
