A sleep mode control device of communication system consists of sleep initialization-decision module, service occupied time statistic module and sleep mode control module both being connected to sleep initialization-decision module separately. Its controlling method is also disclosed.
Description
Technical field
The present invention relates to technical field of communication, relate in particular to the sleep technology of the WiMax system of the communications field.
Background technology
Along with the growth of development of Communication Technique and terminal requirements, data service is developed rapidly, and the increasing rapidly of data business volume makes people grow to even greater heights to the demand of communication bandwidth, and broadband access shows a huge market to industrial circle.For breaking through the bandwidth bottleneck of Access Network, people release multiple broadband access technology.
Adopt the broadband wireless access (BWA of wireless access way, Broadband Wireless Access) technology have flexibly, make things convenient for, remarkable advantages such as mobility and small investment, wherein with 3G (Third Generation) Moblie (3G, The Third Generation), wideband wireless local area network (WLAN, Wireless Local AreaNetwork) and broadband wireless MAN (WMAN, Wireless Metropolitan Area Network) obtain development at full speed in recent years for the BWA technology of representative.
Global general-use inserting of microwave (WiMax, Worldwide Interoperability for MicrowaveAccess) be exactly wherein a kind of wireless metropolitan area network technology, WiMax can provide broadband wireless to connect to equipment fixing or that move, also can be used to connect focus and the internet of WLAN, provide the campus to connect, and the wireless substitute that inserts as digital subscriber terminal line cable broadbands such as (DSL, Digital Subscriber Line) in " last kilometer " broadband access field.
The WiMax system adopts cellular technology, and being transmitted in of its air interface data carried out between base station (BS, Base Station) and several subordinate terminal stations (SS, the Subscriber Station), and carries out centralized control by BS.Wherein, BS and metropolitan area network, public switched telephone network (PSTN, Public Switched Telephone Network) links to each other, a SS can insert one or more terminal (UE, User Equipment), and converge internetworking agreement (IP, Internet Protocol) data, the speech business flow of these UE, be sent to BS by air interface.
During work, terminal and the base station state of keeping in touch, but each terminal is not all with the base station professional transmission to be arranged constantly, therefore, terminal can have professional in some element outage to save the power supply of terminal, be called sleep pattern (Sleep Mode).At present, IEEE802.16E defines a kind of sleep pattern, and terminal and serving BS are broken contact eating dishes without rice or wine with serving BS in the time interval of consulting in advance.Sleep pattern can reduce terminal in descending and up transmission request, thereby minimizes the power consumption of terminal, reduces the interface-free resources consumption that service provides the base station, and then improves the channel resource utilance.
After MS (mobile subscriber, terminal) enters sleep pattern, at sleep state with intercept between state alternately conversion.Under sleep state, MS is not mutual with serving BS Serving BS (i.e. " serving BS "), need not intercept the message of Serving BS yet; Under the state of intercepting, MS must intercept the message of Serving BS, and may carry out interacting message with it according to the indication of Serving BS.The time that each sleep state continuously continues is called sleeping window, and the time of at every turn intercepting state continuance continuously is called listen window.
The IEEE802.16E agreement is set up different Business Streams according to type of service, and requires to take different transmission measures according to the characteristic and the service quality (QoS, Quality of Service) of Business Stream.Simultaneously, for adapting to the characteristics of traffic data transmission, agreement is stipulated three kinds of sleep patterns, and different sleep patterns are taked different sleep strategies respectively, comprises different parameters, different activation and deactivation process and different data transmission policies.
First type: be used for BE, the business of NRT-VR type connects.This type sleeping window becomes two multiple increase up to the sleeping window that arrives maximum prescribed.
Second type: the business that is used for UGS, RT-VR (variable Rate in real time) type connects.Such connection sleeping window and listen window size are in a single day fixing just not to be changed.
The third type: be used for multicast connection and bookkeeping.Such as Perodic ranging, dynamic Service flow operation, face administrative messags such as Cell Broadcast CB.This type for once the length of one's sleep window, once the sleep then just wake up.
Confer terminal and base station, and each current connection is divided into different power-saving groups, adopts different sleep pattern and parameter between group and the group, so the listen window and the sleeping window that different capacity saving group might occur are interweaved.When terminal was in the common factor of sleeping window of all power saving classes, terminal was not carried out any uplink and downlink communication with serving BS, at this moment claims terminal to be among the unavailability interval; In addition, terminal always is in the listen window of those connections of some power saving classes representatives, and terminal can be carried out communicating by letter of up-downgoing with serving BS for these connections, and be called terminal and be among the availability interval this moment.As shown in Figure 1, each current connection is divided into the first power-saving group and the second power-saving group, its empty box indicating listen window, shaded boxes is represented sleeping window, if then terminal is in the shaded boxes common factor of the first power-saving group and the second power-saving group, just represent that terminal is among the unavailability interval, with grid box indicating; Other just represent that terminal is among the availabilityinterval, with left oblique line box indicating.
In unavailability interval, some physical device of terminal may cut off the power supply or carry out other activity (face the base station mutually as scanning, with face the base station mutually do related or the like) and not need and base station communication, and then breath is not delivered a letter to terminal in the base station.
At availability interval, terminal can receive all downlink transfer as normal condition.
At present, activated terminals enters sleep pattern, generally is the sleep pattern that just activates this connection when each service flow activates.
The method of existing activated sleep pattern is not considered the influence of the traffic carrying capacity of current terminal to sleep pattern.The sleep pattern that activates each connection like this when traffic carrying capacity is bigger there is no need, because when traffic carrying capacity is very big, the probability that each professional sleeping window that connects coincides together not is very big, and the time that really enters sleep also just can not be a lot.And this moment, the zero-time and the window size of each sleeping window also will constantly be calculated in terminal or base station, thereby had increased computation complexity and amount of calculation, had improved the complexity of up-downgoing service dispatching simultaneously.
For example system activates a UGS Business Stream, activates this professional sleep pattern that connects simultaneously.If system has activated another or a plurality of of a sort UGS Business Stream again and has activated the sleep pattern of this connection, owing to the service flow parameters unanimity of a plurality of connections determines that the parameter of sleep pattern also is consistent, but as long as the different sleeping windows of a plurality of connections that just may cause of the zero-time of sleep pattern do not overlap, enter sleep pattern if add the connection of other types of service, even all connections have all been slept so, what terminal entered sleep pattern may be also little.And computation complexity and the service dispatching complexity therefore brought are all bigger.
Summary of the invention
Have in view of that, the invention provides method and device that a kind of activated terminals enters sleep pattern, complexity is handled in terminal and base station when entering sleep state to reduce each terminal, reduces amount of calculation, reduces the service dispatching complexity of bringing because of sleep pattern.

As shown in Figure 3, the course of work block diagram for the better embodiment of the control method of the present invention's sleep pattern mainly comprises the steps.
Professional holding time statistical module 21 can be added up the uplink and downlink communication time and the free time of terminal and base station after whenever distributing a frame, and the relation commentaries on classics calculation of call duration time and free time is the P value.Wherein, the statistical method of professional holding time statistical module 21 mainly contains three kinds, and promptly definite method of P value mainly contains following four kinds:
Method one: the cumulative time is average
During starting up of terminal or sleep pattern separated when activating, just begin to add up call duration time and free time, the P value be call duration time divided by call duration time and free time sum.As shown in Figure 4, establishing the time started is t
0, the current time is t, T
iFor begin the call duration time segment that has communication to the current time from timing, then the computational methods of P value can be as the formula (1):
But the cumulative statistics time can not endless, can be after one long period be t from newly picking up counting
0
Method two: sliding window is average

Method three: weighted average in the sliding window
Some professional connection may not have transfer of data for a long time, so this connection business appears later on and need take the probability in transmission time may be less than normal, this connection holding time can be set so be multiplied by weights less than 1 coefficient, because being miscellaneous service, the communication holding time connects the time that mixes, therefore, weights a
iDesign will with the current business hours T that communicates
iIn type of service relevant, then the computational methods of P value can be as the formula (3):
Method four: the ratio of call duration time and free time
During starting up of terminal or sleep pattern separated when activating, measurement period is set, statistics call duration time and free time in each cycle, the P value is the ratio of call duration time and free time.
Professional holding time statistical module 21 is passed to sleep with the P value of statistics and is initiated judging module 23, then sleep initiation judging module 23 compares the threshold value that this P value and one sets in advance, this thresholding system by communication with free time ratio module 22 setting is set, in this way the P value less than communication with free time ratio the threshold value that module 22 is provided with is set, then the condition of initiating sleep pattern is satisfied in explanation, then sleep initiation judging module 23 will activate each definite information that connects sleep pattern and pass to sleep pattern control module 24, enter step 303; Otherwise get back to step 301.
Sleep pattern control module 24 determines that according to sleep initiation judging module 23 information send activation instructions, and is responsible for separating instruction and sleep pattern management, the sleep initiation judgement etc. of activated sleep pattern.
Sleep pattern control module 24 activates each power-saving group, and the time that occurs according to the calculation of parameter unavailability interval of power-saving group, and in this unavailability interval, select the part components and parts to cut off the power supply, perhaps carry out other activity and do not need and base station communication: the base station is faced in scanning mutually, and faces the base station mutually and does related or the like.
When terminal is in sleep pattern, have only a connection to be separated activation, this terminal withdraws from sleep pattern, and whole terminal enters normal operating conditions, gets back to step 301, and professional holding time statistical module 21 is added up current terminal communication state again, and uses the P value representation.
