Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one
Present embodiment provides a kind of sub-district method for saving energy, referring to Fig. 1, realizes that the method for the embodiment of the invention comprises the steps:
Step S101:, judge whether carrier frequency satisfies the trigger condition of moving to the target energy saver mode, if satisfy execution in step S102 according to the state of carrier frequency.
In the present embodiment, at first need carrier frequency is defined several mode of operations the working method of the corresponding a kind of carrier frequency of each mode of operation, wherein, except carrier frequency did not carry out any energy-conservation mode of operation, other mode of operation can be called the energy conservation pattern, hereinafter to be referred as energy saver mode.Be operated in the carrier frequency degree of power conservation difference on the different energy saver modes.
For example, can be defined as follows several mode of operations for carrier frequency:
Mode of operation 0: the carrier frequency that is in this mode of operation does not carry out energy-conservation;
Mode of operation 1: comprise that specific transactions is limited and the specific user is limited, the carrier frequency that is in this mode of operation will only can provide specific transactions, or only provide service to the specific user in order to save resource consumption.Specific transactions is limited can be to limit the concrete service access of certain class, as limiting VOIP (Voice over Internet Protocol, the networking telephone) business, high-speed data service access etc.; Also can be that specific transactions only is provided, as VOIP business etc. only is provided.The specific user is limited can be that the restriction specific user inserts, as user's access of restriction low priority; Also can be only to provide service, as only providing service to Gold Subscriber to the specific user;
Mode of operation 2: carrier frequency is closed, and the carrier frequency that is in this mode of operation is fully closed, without any energy resource consumption.
Need to prove, in actual applications, definition can not only be confined to three kinds of mode of operations of above-mentioned understanding to the mode of operation of carrier frequency, and is also different to the concrete definition of mode of operation simultaneously, and the concrete definition of above-mentioned mode of operation is not constituted restriction to the embodiment of the invention.
Here, for convenience of description, the energy saver mode that will move to is called the target energy saver mode.
The trigger condition of moving to the target energy saver mode can be followed one of following several principles or combination in any:
1) Event triggered principle.This principle is meant by predefined incident and triggers closing of carrier frequency when satisfying condition.For example, based on the Event triggered of load information, when the load on the carrier frequency is less than or equal to preset first threshold, then triggers this carrier frequency and move on the target energy saver mode.Load can be PRB (Physical Resource Block, the Physical Resource Block) resources occupation rate in the certain hour, activated state user's number, Idle state user's number etc.Idle state user's number can pass through the measurement period tracking area, and (TrackingArea, TA) the user UE number that upgrades is estimated.It is pre-configured that first threshold value of these incidents can be passed through OAM (Operation and Maintenance, Operation ﹠ Maintenance System).The value of first threshold value is determined according to carrier policy and network planning data, is not done qualification in the embodiment of the invention.As first thresholding is 0 o'clock, then is illustrated in when not having load fully on the carrier frequency, just triggers carrier frequency and moves on the target energy saver mode.If triggering thresholding is not 0 o'clock, starting before carrier frequency moves to the target energy saver mode, also to consider abutting subdistrict or with the loading condition of other carrier frequency in the sub-district.After avoiding sub-district/base station to close, cause that the overweight situation of abutting subdistrict/base station load occurs.
2) the professional principle that triggers.This criterion is meant uses the user UE number of certain class business to be less than or equal to certain predefined load-threshold value within a certain period of time on the carrier frequency, hereinafter referred to as second threshold value.As, when not having LTE professional on the carrier frequency in the sub-district of a LTE (Long Term Evolution, Long Term Evolution) system, then trigger this carrier frequency is moved on the target energy saver mode.
3) periodic triggers principle.This criterion is meant that triggering cell was moved on the target energy saver mode when time arrived Preset Time.Can be in the network planning stage, according to the cycle of traffic model initial configuration triggering.Also can be in the network operation stage, according to the every performance index and the actual traffic measurement data of network, dynamic-configuration triggers the cycle.
Step S102: determine whether above-mentioned carrier frequency can move on the target pattern, if can, execution in step S103 then.
Wherein, determining whether carrier frequency can move on the target pattern can specifically comprise following several method:
Method 1: static configuration method.In the network design stage, when doing plot planning, determine according to the geographical location information of planning sub-district and the coverage information in this geographical position whether this carrier frequency can move on the target energy saver mode.For example, if in the carrier frequency coverage of certain sub-district, have other sub-district to provide alien frequencies or different system to cover simultaneously, then definite this carrier frequency can be moved on the target energy saver mode.But need avoid all being moved on the energy saver mode of closing fully of all sub-districts in this geographical position.
In actual applications, can safeguard a property value to this carrier frequency in advance, can be called transportable property value, this property value represents whether this carrier frequency can be moved on the energy saver mode.For example, can in the base station of respective cell, dispose this property value, and utilize OAM to be configured, particularly, as shown in Figure 2, comprise:
Step S201:OAM 202 utilizes the property value of the carrier frequency in each sub-district in configuration management (CM, Configuration Management) the message arrangement base station of interface of 201 of OAM202 and base stations.
Step S202: base station 201 utilizes the configuration management message of the interface of 201 of OAM 202 and base stations to send the configuration response message to OAM 202.
Method 2: dynamic decision method.In the network operation process, according to the running status of network, the information such as measurement report of the load information of carrier frequency and user UE judge whether carrier frequency can move on the target energy saver mode.
In practice, the executive agent of above-mentioned judgement action can be OAM or sub-district, carrier frequency place relevant base station.Similarly, also can safeguard a property value to this carrier frequency in this method, this property value represents whether this carrier frequency can be moved on the energy saver mode.Also need to avoid all being moved on the energy saver mode of closing fully of all sub-districts in this geographical position.Might as well be the specific implementation that example describes this dynamic decision method in detail below this carrier frequency is safeguarded above-mentioned property value.Wherein, the span of above-mentioned property value can be defined as and comprise very and false, and corresponding respectively carrier frequency can be moved on the energy saver mode and cannot be moved on the energy saver mode.
Above-mentioned dynamic decision method can comprise: same coverage criterion.Whether the decision condition of this criterion is to have other sub-district or base station that the covering of different frequency/different system is provided simultaneously in the scope that covers of cell carrier frequencies.
Should can be one of following or combination in any with the specific implementation method that covers principle:
A) user UE measures the adjacent area, if in one section timing statistics, have at least a signal quality of adjacent cells to reach certain threshold value in all adjacent areas that user UE reports, for example more than or equal to the 3rd threshold value, exist other sub-district or base station that the covering of different frequency/different system is provided simultaneously in the scope that then shows cell carrier frequencies and covered, this moment, the base station reported this information to give OAM, and the attribute with this carrier frequency after OAM confirms is changed to very; Perhaps base station oneself is revised the attribute of this carrier frequency and is notified OAM.
B), adding that sub-district geography information and coverage information comprehensively judge based on existing different frequency/different system adjacent area in the Neighboring Cell List in the sub-district.As shown in Figure 3, for providing with the judgment condition that covers by a sub-district A to sub-district B is R＞r, and R＞=d+r, wherein R is the radius of sub-district A, r is the radius of sub-district B, after satisfying above-mentioned condition, can think that sub-district B satisfies with the requirement that covers, the property value whether this carrier frequency of expression that can sub-district B can be moved on the energy saver mode is set to "Yes".
Step S103: carrier frequency is moved on the target energy saver mode.
Step S104: the target energy saver mode that carrier frequency is moved to is notified to terminal.
Wherein, the work at present state of carrier frequency in the broadcast cell in system broadcast message perhaps passes through the change of beep-page message informing user terminal UE working state of system.
After carrier frequency is moved on the target energy saver mode, can also notify the current state information of sub-district, adjacent node above-mentioned carrier frequency place.
Wherein adjacent node comprises adjoining base station, all MME (Mobility Management Entity, mobile management entity) in the pool (pond), OAM.A resource pool forming by a plurality of MME of pool wherein.
As shown in Figure 4, the specific implementation of above-mentioned notice adjacent node can comprise:
Step S401: sub-district, the carrier frequency place relevant base station 401 of moving on the energy saver mode sends base station configuration updating information to adjacent nodes such as adjoining base station, MME or OAM 402, notice adjacent node 402, the mode of operation after carrier frequency switches in this sub-district.
In the practical application, message name may be different, can use as long as can finish the message of identical or similar functions.Carry carrier frequency in the message and move to indication on the target energy saver mode, or carry the cause value of this switching.Can also carry the cell ID at this carrier frequency place in the message, as E-CGI (E-UTRAN Cell Global Identifier, the cellular global identity of evolution), CGI (Cell Global Identifier, cellular global identity) or PCI information such as (Physical Cell Identity, Physical Cell Identifier).Go back the current ability information of portability sub-district in the message, this ability information includes but not limited to: the sub-district is to the enabling capabilities of business and the sub-district enabling capabilities to function, and the sub-district can comprise the ability of making of function: whether support to resemble MANET function and radio resource management functions such as automatic adjacent section management, mobility optimization, interference coordination, load balancing.These cells are option.
Step S402: adjacent node 402 is preserved the response configuration information, and handles accordingly.Above-mentioned respective handling comprises: upgrade NRT (Neighbor Relation Table, neighborhood region correlation chart) state of sub-district in the table, and writing down concrete state information and cell capacity information, this ability information includes but not limited to that the sub-district is to the enabling capabilities of business and the sub-district enabling capabilities to function.If the work at present pattern of all carrier frequency of sub-district is for closing fully, then adjacent node can also be deleted this sub-district.MME is according to buttoned-up sub-district and state thereof in the Notification Record TA.If all carrier frequency of all sub-districts all enter the mode of operation of closing fully in the TA, then follow-uply in this TA, do not initiate paging.
Step S403: adjacent node 402 sends the base station configuration updating response message to the base station 401 of sub-district, the carrier frequency place correspondence of moving to the target energy saver mode.This step is optional, and can exchange execution sequence with step S402.
After carrier frequency is moved to the target energy saver mode, also can discharge respective resources or interface according to the definition of this target energy saver mode.
In addition, can also comprise the process that cell carrier frequencies is activated in the method that the embodiment of the invention provides.Wherein activate and comprise moving to not having energy-conservation mode of operation, also can comprise and moving to than on the slightly little energy saver mode of the degree of power conservation of current energy saver mode from energy saver mode.
Above-mentioned activation can comprise following several method:
Method 1: the Idle state user activates the carrier frequency of sub-district.Specific implementation comprises:
Realize 1): the Idle state user initiatively initiates service request, in the activation of stage triggering cell carrier frequency that connects.Or
Realize 2): the Idle state user receives the beep-page message that network side sends, when sending page response, the activation of triggering cell/base station.
Method 2: switching command activates.The activation of cell carrier frequencies is carried out in sub-district, carrier frequency place when receiving the handoff request order.Can comprise in concrete the application that the switching activation of X2 interface and the switching of S1 interface activate.
Fig. 5 shows and utilizes X2 interface to switch the schematic diagram of activation.X2 interface is the interface that is connected between base station and the base station in E-UTRAN (Evolved Universal Mobile Telecommunications System Territorial Radio Access Network, the universal mobile telecommunications system land radio access web of the evolution) network configuration.As shown in the figure, comprise the steps:
Step S501: the carrier frequency activation command is received in base station 501.
Step S502: if the X2 interface transmission link discharges, then rebulid the transmission link of X2 interface, i.e. SCTP (Stream Control Transmission Protocol, SCTP) coupling connection to adjoining base station 502.
Step S503: base station 501 sends X2 to adjoining base station 502 and sets up message, carries cell carrier frequencies in the message and activates the notice indication, or notify the activation of adjoining base station sub-district by specific messages.
Step S504: adjoining base station 502 sends to base station 501 and activates push-notification-answer message.
Fig. 6 shows and utilizes the S1 interface to switch the schematic diagram of activation.The S1 interface is the interface that connects between base station and MME or SAE (SystemArchitecture Evolution, the System Architecture Evolution) gateway in the E-UTRAN network configuration.As shown in the figure, comprise the steps:
Step S601: the cell carrier frequencies activation command is received in base station 601.
Step S602:, then rebulid the transmission link of S1 interface, i.e. SCTP association to MME 602 if S 1 interface transmission link discharges.
Step S603: base station 601 sends S1 to MME 602 and sets up message, carries cell carrier frequencies in the message and activates the notice indication.Or the activation by specific messages notice adjoining base station sub-district.
Step S604:MME 602 sends to base station 601 and activates push-notification-answer.
Method 3: network side activates.Network others node such as adjoining base station, MME, OAM triggers the activation by explicit signaling.
Method 4: Event triggered activates.After the traffic carrying capacity in the coverage of sub-district, carrier frequency place or load acquire a certain degree (or thresholding), for example, greater than the 4th predetermined threshold value, the activation process of system triggers cell carrier frequencies.
Method 5: regularly activate.Predefined activationary time arrives, and then activates carrier frequency.
After carrier frequency in the sub-district carried out activation manipulation, adjacent node or OAM can also be notified in the sub-district.
More than in description process to technical scheme, directly the implementation mode switch to as if the sub-district in carrier frequency, those skilled in the art should be understood that, in actual applications, also can carry out whole change action to the carrier frequency in the whole sub-district, can for example can comprise the several mode of operations of little area definition this moment:
Mode of operation 0: normal operating conditions.The sub-district that is in this state is not carried out energy-conservation.
Mode of operation 1: specific transactions is limited or the specific user is limited.The sub-district that is in this state will only can provide specific transactions, or only provide service to the specific user in order to save resource consumption.Specific transactions is limited can be to limit the concrete service access of certain class, as limiting VOIP business, high-speed data service access etc.; Also can be that specific transactions only is provided, as VOIP business etc. only is provided.The specific user is limited can be that the restriction specific user inserts, as user's access of restriction low priority; Also can be only to provide service, as only providing service to Gold Subscriber to the specific user.
Mode of operation 2: be in the sub-district of this state, the transmission cycle of descending synchronous signal channel and broadcast channel is extended.In each intermittent phase that sends the cycle, will stop to send common down channel, reach energy-conservation purpose.
Mode of operation 3: down channel is limited.The sub-district that is in this state is in order to save energy, close descending channel, the up accepting state that still keeps of sub-district, descending all dedicated channels of closing of sub-district, cell downlink only keeps sending SCH (Synchronization Channel, synchronizing channel) and BCH (Broadcast Channel, broadcast channel), that is to say that the sub-district is at the descending host system message block that still sends synchronizing channel and system.
Mode of operation 4: particular channel is limited, and the carrier frequency that is in this mode of operation can only be closed downstream data channel reservation Common Control Channel, perhaps closes the up-downgoing data channel and keeps down control channel and uplink random access channel.Under this pattern, each channel is separately to consider.
Mode of operation 5: be in the sub-district/base station of this state, except that the attribute with mode of operation 3, the X2/S1 interface link of sub-district also is in closed condition.
Mode of operation 6: the sub-district is closed.The sub-district that is in this state will be fully closed, without any energy loss.
Mode of operation 7: carrier frequency is closed.Be in the multicarrier system of this state,, one or several subcarrier frequency closed, run on main carrier frequency and other subcarrier frequencies as LTE Advance (LTE-A) system; Perhaps all subcarrier frequencies are closed, run on the main carrier frequency.Be in the multi-carrier frequency cell of this state, as the sub-district of TD-SCDMA system, just one or several carrier frequency is closed, and runs on main carrier frequency and other subcarrier frequencies; Perhaps all subcarrier frequencies are closed, run on the main carrier frequency.
From the definition of above-mentioned mode of operation, the definition of the mode of operation of sub-district is associated with the mode of operation definition of its interior carrier frequency as can be seen, for example, when all carrier frequency all were in the mode of operation of closing fully in the sub-district, the work at present pattern of sub-district should respective cell be closed.
Those skilled in the art should be understood that switches and can finish by the mode of operation of wherein corresponding carrier frequency is switched the mode of operation of sub-district.
In like manner, for also can pre-defined several mode of operations by the base station of a plurality of sub-districts correspondence, these mode of operations interrelate with the mode of operation of its corresponding district again.Therefore, the mode of operation of base station being switched also can be by finishing the switching of carrier frequency mode of operation.
In the E-UTRAN network, introduced the notion of tracing area (TA, Tracking Area).In a cordless communication network, a tracing area (TA, Tracking Area) is by a Tracking Area Code (Tracking Area Code, TAC) unique identification.A tracing area (TA, Tracking Area) can comprise one to a plurality of sub-districts.Different districts in base station can belong to different tracing areas (TA, Tracking Area).But, in the practical application, generally one or more base station of doing are divided into a tracing area (TA, Tracking Area) for convenient management.Also can define several mode of operations for tracing area like this, get in touch, so also can finish by switching to the mode of operation of carrier frequency to the switching of the mode of operation of tracing area and exist between the mode of operation of these mode of operations and base station.
In addition,, improve the availability of frequency spectrum, in the LTE-A mobile communication system, proposed the notion of carrier aggregation (Carrier Aggregation) in order to realize higher peak rate.The basic principle of carrier aggregation (Carrier Aggregation) is in the LTE-A mobile communication system a plurality of carrier waves to be carried out polymerization to realize the transmission bandwidth greater than 20MHZ.Carrier aggregation (Carrier Aggregation) is divided into two kinds of situations, and a kind of is that a plurality of LTE carrier aggregation become a single LTE-A carrier wave, is called the polymerization of intercarrier.LTE carrier aggregation as 5 20MHZ is a LTE-A carrier wave with 100MHZ bandwidth.Another kind is the polymerization between a plurality of frequency spectrum sheets (Spectrum Aggregation), is called spectrum aggregating (Spectrum Aggregation).This shows, also can utilize carrier aggregation to carry out the definition of mode of operation, and the handoff procedure of carrier aggregation mode of operation also can be finished by the mode of operation of wherein carrier wave is switched.
Particularly, when all carrier frequency in the sub-district satisfy when moving to the condition of energy saver mode, trigger on the target energy saver mode that described sub-district switches to the sub-district.
When the condition of moving to energy saver mode is all satisfied in all sub-districts in the base station, trigger on the target energy saver mode of moving to the base station in described base station.
When the condition of moving to energy saver mode is all satisfied in all base stations in the tracing area, trigger described tracing area and move on the target energy saver mode.
