After adjustment cycle finished, the base station was judged according to the voltage that detects in this adjustment cycle and is satisfied the recovery condition, then recovers continued power.Wherein, the recovery condition comprises: the input voltage value that detects is higher than default first threshold, perhaps detect one fixedly in the duration changing value of input voltage be no more than default Second Threshold.
As shown in Figure 1, base station system is comprised of several parts such as economize on electricity Monitoring and Controlling unit, network data processing unit, downlink processing unit, common control unit, up processing unit, downstream signal transmission processing unit and upward signal monitoring receiving elements.
Concrete function and the processing procedure of each component units are described below.
1, economize on electricity Monitoring and Controlling unit.This unit links to each other with system power supply, and it can continue to detect supply voltage, and according to current treatment situation control base station power supply or the power saving of testing result and system, thereby control its power consumption.System power supply may derive from electric power networks, battery or both use simultaneously.
1) for the electric power networks power supply, if voltage stabilization perhaps has shake but the still normal safe operation of energy assurance system, any action is not carried out in this unit.If brownout (being that supply voltage is lower than the 3rd default threshold value) or shake excessive (variable quantity that namely detects supply voltage in a duration is greater than the 4th default threshold value), normally safe operation of base station, then this unit can send the message of an interruption of power supply, sends to up processing unit and downlink processing unit via common control unit.No matter whether receive feedback, through a predetermined time every (T-waiting) afterwards, can report the abnormity of power supply alarm to operation maintenance center, simultaneously interrupt system power supply namely no longer is sent to source current each other unit in this base station.The base station enters off-position.
Recover normal when detecting supply voltage, perhaps voltage dithering remain on system can normally safe operation scope in, and keep a period of time after (T-checking), each unit is electrically connected in this cell conduction system power supply and this base station, namely the base station is restored electricity, report simultaneously the recovery of abnormity of power supply alarm to operation maintenance center.System enters normal condition.
Wherein T-waiting and T-checking are solidificated in system, perhaps set by configuration mode.
2) for battery supply, usually to use wind energy or solar energy that battery is charged.When some natural cause caused these energy deficiencies, battery just needed to save to use, and uses as far as possible for a long time to guarantee it.
As shown in Figure 2, when detecting voltage and be higher than first threshold Th-normal, do not carry out any action, system's normal power supply.When voltage was lower than Th-normal but is higher than the 3rd threshold value Th-saving, this unit can send an economize on electricity message, sends to up processing unit and downlink processing unit via common control unit.
If all requiring to postpone, the feedback of the up processing unit of receiving and downlink processing unit enters electricity-saving state, then this unit will be at a fixed time interval (T-rechecking) afterwards, according to the voltage condition that in this T-rechecking duration, detects, as judge and satisfy the economize on electricity condition, then again send economize on electricity message.
If postponing, any one feedback failed call of the up processing unit of receiving and downlink processing unit enters electricity-saving state, then according to current voltage, determine that the value in economize on electricity cycle and power-up period in the adjustment cycle is as one group of economize on electricity data, wherein power-up period is illustrated in system's normal power supply in this duration, and the economize on electricity cycle represents long interior interrupt system power supply this moment.The economize on electricity data be should organize via common control unit, up processing unit, downlink processing unit and upward signal monitoring receiving element sent to.After this parting system power supply in the economize on electricity cycle duration, the base station enters electricity-saving state.
When the base station is in electricity-saving state, if detecting cell voltage in current adjustment cycle, economize on electricity Monitoring and Controlling unit continues to reduce, then after this adjustment cycle finishes, redefine the economize on electricity periodic quantity, namely increase the economize on electricity cycle, otherwise then reduce.And the economize on electricity periodic quantity that redefines according to this in next adjustment cycle is carried out power down process.If the economize on electricity cycle changes, can send to up processing unit, downlink processing unit and upward signal monitoring receiving element via common control unit by the economize on electricity updating message.Then the economize on electricity periodic quantity that redefines according to this in next adjustment cycle of this unit is carried out power down process.
Again be higher than Th-normal when detecting voltage, and keep a period of time (T-checking) afterwards, this unit can send an economize on electricity message recovery, send to up processing unit, downlink processing unit and upward signal monitoring receiving element via common control unit, restore electricity simultaneously.After this system enters normal operating conditions.
When detecting voltage and be lower than the 3rd threshold value Th-saving, this unit can send an interruption of power supply message, sends to up processing unit and downlink processing unit via common control unit.No matter whether receive feedback, at a fixed time interval (T-waiting) afterwards, can report the abnormity of power supply alarm to operation maintenance center, simultaneously interrupt system power supply.System enters off state.
Again be higher than Th-saving when detecting voltage, and keep (T-checking) after a period of time, this unit recovery system power supply.After system's normal operation, this unit can send one group of default economize on electricity data and (comprise default power-up period value, default economize on electricity periodic quantity), send to up processing unit, downlink processing unit and upward signal monitoring receiving element via common control unit.After this system enters electricity-saving state according to the value of these economize on electricity data, reports simultaneously the recovery of abnormity of power supply alarm to operation maintenance center.Default economize on electricity data write is perhaps set by configuration in system.The processing of electricity-saving state and as mentioned above, is no longer given unnecessary details at this.
Wherein Th-normal, Th-saving, T-rechecking are solidificated in system, perhaps set by configuration mode.
3) for electric power networks power supply and the simultaneous situation of battery supply, this unit can continue to detect electric power networks supply voltage and cell voltage simultaneously.Then according to testing result, can be divided into a few class situations, specifically process as follows:
I: the electric power networks power supply is normal, uses the electric power networks power supply;
Ii: the electric power networks power supply is unusual by normally becoming, and selects battery supply, and last handling process and 2) identical;
Iii: electric power networks power supply persistent anomaly, select battery supply, processing procedure and 2) identical;
Iv: the electric power networks power up is normal, and continues for some time (T-checking) afterwards, uses electric power networks.
In addition, the embedded charge-discharge modules in this unit, in the base station system normal power supply, charge-discharge modules is recharged, and this unit uses the system power supply power supply simultaneously.When system power supply is abnormal, charge-discharge modules will discharge, and also can work with this understanding to guarantee this unit, thereby guarantee that this unit can both make correct detection and judgement to system voltage under any condition.
2, network data processing unit is responsible for finishing the transmitting-receiving of data mutual between base station and network side network element.Network side data is sent to the downlink processing unit via common control unit after this cell processing; The data of eating dishes without rice or wine are sent to this unit via common control unit after up processing unit processes is finished, send to corresponding network side network element by this unit again.For example, the data transmit-receive of the R6/R8 interface in WiMAX (Worldwide Interoperability for Microwave Access, the worldwide interoperability for microwave access) base station system; The perhaps data transmit-receive of X2/S1 interface in LTE (Long Term Evolution, the Long Term Evolution) base station system.This unit does not participate in the energy-conservation decision-making of base station system.When base station system is electricity-saving state or off state, this unit will quit work.
3, the answer of the distribution of processing, interface-free resources of downlink business and all kinds of requests of terminal use or initiation etc. are responsible for finishing in downlink processing unit.Downlink data sends to the terminal use through the downstream signal transmission processing unit.Downlink data is comprised of broadcast data, multi-case data and unicast data usually.Broadcast data may need periodically to send; Multicast and unicast data then are just to need to send when the terminal use has business or data accordingly.The method of salary distribution of interface-free resources mainly contains two kinds, and a kind of is to continue the method for salary distribution, and a kind of is the distribution according to need mode.Lasting distribution refers in some cycles, continues to terminal use's Resources allocation, until end-user service finishes or sends the request of termination, is generally used for distributing ascending resource; Distribution according to need refers to the needs according to the terminal use, and for example the resource quantity of data volume waiting for transmission or user request is come the Resources allocation to the terminal use.On down direction, generally be to determine whether to send the extend request message in economize on electricity cycle according to data volume waiting for transmission; Up, generally be to determine whether to send the extend request message in economize on electricity cycle according to request quantity.As ask quantity to reduce or data volume waiting for transmission minimizing, and then can be among these terminal uses and various types of traffic, some terminal use or some type of service have higher priority, then should be by priority treatment in power-up period.For example, emergence call service should be sent out with limit priority, and Gold Subscriber has higher priority etc. than other users.
That economize on electricity Monitoring and Controlling unit sends when receiving, when sending to the interruption of power supply message of this unit via common control unit, the power supply that base station system is described is not enough, will be by very fast shutoff, this unit is after the work such as release of finishing the storage of necessary data, terminal use's resource, reply a response message for economize on electricity Monitoring and Controlling unit via common control unit, the waiting system power supply is turned off simultaneously.
That economize on electricity Monitoring and Controlling unit sends when receiving, when sending to the economize on electricity message of this unit via common control unit, illustrate that electricity shortage appears in the base station, must the power saving use.This unit sends response message to node monitoring control notice of invitation unit, enters electricity-saving state.
When receiving the economize on electricity message recovery, this unit does not process, and the state that only records base station system is normal condition.
As shown in table 1, four kinds of states are safeguarded in this unit, and concrete processing procedure is as follows:
1) after this unit starting, is in normal condition.Receive after the economize on electricity message, enter a class power down mode, reply simultaneously response message, suggesting system for wearing is postponed and is entered electricity-saving state;
When 2) being in a class power down mode, if again receive economize on electricity message, state is constant so, directly replys response message, accepts base station system and enters electricity-saving state.At this state, the state of the base station system of this unit record of meeting cycle detection if the base station system state is normal condition, continues for some time (T-checking) afterwards so, and this unit enters two class power down modes.
When 3) being in two class power down modes, if receive economize on electricity message, will become at once a class power down mode, and reply simultaneously feedback message, suggesting system for wearing is postponed and is entered electricity-saving state.The state of the base station system of this unit record of meeting cycle detection if the base station system state is normal condition, continues for some time (T-checking) afterwards so under this state, and this unit enters three class power down modes.
When 4) being in three class power down modes, if receive economize on electricity message, will become at once a class power down mode, and reply simultaneously feedback message, suggesting system for wearing is postponed and is entered electricity-saving state.The state of the base station system of this unit record of meeting cycle detection if the base station system state is normal condition, continues for some time (T-checking) afterwards so under this state, and this unit enters normal condition.
The status list of table 1 downlink processing unit
Be under a class, two classes, the three class power down modes, the processing of data is finished in this unit, and after the downstream signal transmission processing unit is sent completely, will close at once the downstream signal transmission processing unit.Until open again before sending next time.And under the normal condition, the downstream signal transmission processing unit will normally be opened always.
4, downstream signal transmission processing unit is used for finishing transmission and the transmission of downlink data after the result that receives the downlink processing unit.This unit does not participate in the energy-conservation decision-making of base station system.At base station system electricity-saving state or off state, this unit will quit work.
5, common control unit is mainly finished the Storage and Processing of common data, message, event.Interacting message, data between these different units such as network data processing unit, up processing unit, downlink processing unit, economize on electricity Monitoring and Controlling unit, upward signal monitoring receiving element are stored and are read, event handling, all finish by this unit.This unit does not participate in the energy-conservation decision-making of base station system.At electricity-saving state or the off state of base station system, this unit will quit work.
6, up processing unit is used for finishing reception and the processing of upstream data.If the activated terminals number is many in the system, perhaps the upstream data amount is larger, and base station system just needs to consume the more time and resource is processed upstream data.Otherwise then the processing of upstream data time and the resource that need to consume is just fewer.In the electric weight deficiency of base station, upstream data is processed and be finished with time and the resource consumption of minimum.The data of up processing mainly contain three kinds, and a kind of is terminal use's business datum, and another kind is terminal use's ascending resource request, and the third is the control message between terminal use and the base station.Business datum finally can send to the network side network element through network data processing unit.Terminal use's ascending resource request sends to the downlink processing unit through common control unit, the downlink processing unit can determine distributable quantity according to terminal use's state, available resources and user profile etc., and allocation result finally can send to the terminal use.Control message is then by up processing unit processes, and result sends to the downlink processing unit through common control unit, and finally can send to the terminal use.
That economize on electricity Monitoring and Controlling unit is sent when receiving, when sending to the interruption of power supply message of this unit via common control unit, the power supply that base station system is described is not enough, will be by very fast shutoff, this unit is after the work such as release of finishing the storage of necessary data, terminal use's resource, reply a response message can for economize on electricity Monitoring and Controlling unit, wait for that simultaneously power supply is turned off.
That economize on electricity Monitoring and Controlling unit is sent when receiving, when sending to the economize on electricity message of this unit via common control unit, if the current power down mode that is not in this unit, to enter power down mode, and reply simultaneously response message, the suggestion base station system postpones to enter power down mode; The current power down mode that is in this unit will be replied response message, accept base station system and enter power down mode.
Particularly, two kinds of operating states are safeguarded in this unit: normal condition, power down mode, and concrete processing procedure is as follows:
1) this unit initial condition is normal condition, receives after the economize on electricity message, will open upward signal monitoring receiving element, replys simultaneously response message, and suggesting system for wearing is postponed and entered electricity-saving state, and this unit enters power down mode simultaneously.
When 2) being in power down mode, in power-up period, except following two kinds of conditions, all the other times, this unit quit work.One, upward signal monitoring receiving element has detected legal signal, will start this unit and work within a time interval (T-working), and upward signal monitoring this moment receiving element is closed, and uplink receiving is processed and is reverted to normal condition; Surpass after this interval, will again open upward signal monitoring receiving element.They are two years old, the downlink processing unit is according to the interface-free resources allocation result, send this unit of message informing through common control unit and need to receive upstream data in the next frame period, upward signal monitoring receiving element will be closed in this unit before the next frame period begins, uplink receiving is processed and reverted to normal condition; After a frame period finished, start signal was surveyed receiving element again.If receive economize on electricity message at power down mode, will directly reply response message, accept base station system and enter electricity-saving state.If receive the economize on electricity message recovery, this unit reverts to normal condition, and upward signal monitoring receiving element is closed, and uplink receiving is processed and reverted to normal condition.
Wherein T-working is solidificated in system, perhaps sets by configuration mode.
7, upward signal monitoring receiving element comprises two kinds of functions: upward signal is surveyed and upward signal receives.
Within the power saving cycle of the electricity-saving state of base station system or off state, this unit will quit work.
Under normal condition, the upward signal detecting function is closed, the normal operation of upward signal receiving function.
When up processing unit enters power down mode, in power-up period, the detecting function that upward signal is surveyed receiving element is opened, only receive upward signal this moment in a very little interval, if the signal power that detects surpasses certain threshold value (Th-signal), to trigger the normal operation of upward signal receiving function, and notice is to up processing unit.At this moment, the upward signal detecting function is closed, the normal operation of upward signal receiving function.At a fixed time interval (T-working) afterwards, up processing unit will be opened the upward signal detecting function again.Within the power saving cycle, upward signal monitoring receiving element is closed again.
Wherein Th-signal is solidificated in system, perhaps sets by configuration mode.
