Description

A kind of cell energy-saving compensation coordination approach and equipment

Technical field

The present invention relates to wireless communication technology field, relate in particular to a kind of cell energy-saving compensation coordination approach and equipment.

Background technology

Reduce energy resource consumption, reducing CO2 emission is one of target of sustainable development of modern society.Cordless communication network will be disposed a large amount of base stations conventionally, normally works in these base stations for 24 hours incessantly, and therefore, every day, the base station of mobile communications network all will consume a large amount of energy.In order to reduce energy consumption, realize green communications network, at LTE(Long Term Evolution, Long Term Evolution) and LTE-A(LTE-Advanced, senior Long Term Evolution) in system, introduce power-saving mechanism, its principle is when network load is low weight, the community of closed portion base station, utilize other base station cells that service is provided, reach energy-conservation object.

1) cell energy-saving under overlapping covering (overlapping) scene

Existing cell energy-saving mechanism is for the scene that has overlapping covering, by LTE/LTE-A macrocell (Marco Cell), provide basis to cover, and the low LTE/LTE-A base station cell of some transmitting powers covers as focus, Hot Spot (Hotspot cell) is positioned at the coverage of macrocell, as shown in Figure 1, wherein macrocell provides basic covering, and other Hot Spot provide focus to cover.

Under overlapping covering scene, the Main Function of Hot Spot is to provide higher network capacity.When in network, duty ratio is higher, these Hot Spot need to open (activating), to provide required service for user, when load is low weight, by the E-UTRAN(Evolved-Universal Terrestrial Radio Access Network that provides basis to cover, the universal terrestrial access network of evolution) or GERAN(GSM(Global System for Mobile Communications, global system for mobile communications)/EDGE(Enhanced Data Rate for GSM Evolution, enhanced data rates for gsm evolution technology) Radio Access Network, GSM EDGE Radio Access Network network)/UTRAN network provides service for user, these Hot Spot can be closed (being deexcitation), reach energy-conservation object.

Community activation/deactivation mechanism: under the state of activation of community, can normally work in community, can normally send various physical layer signals and carry out transfer of data.Under the deactivation status of community, community can not send any signal, can not with UE(User Equipment, subscriber equipment) between carry out data transmit-receive, UE cannot connect with community.

Concrete Hot Spot deexcitation mechanism mainly contains several as follows:

A), based on OAM(Operation Administration and Maintenance, operation management maintain) control;

B), provide base station independently deexcitation when there is no business datum of focus covering whole/part community;

C), based on macro base station, control.

When the base station that provides focus to cover determines its lower certain community of deexcitation, can be switched to other communities by the UE of Jiang Gai community in connected state, and in handover request, indicate switch reasons, avoid these communities that UE is switched to this deactivating cell again.In addition, provide the base station of focus covering when its lower certain community of deexcitation, can be switched to other communities by the UE of Jiang Gai community in connected state, and in handover request, indicate switch reasons, avoid these communities that UE is switched to this deactivating cell again.In addition, provide base station that focus covers behind deexcitation certain or some community by inter-base station interface its lower which community of having notified this focus coverage base station deexcitation of adjacent base station.

After Hot Spot is deactivated, once provide the load of the community of basis covering to surpass its level that can bear, need so to activate one or more Hot Spot.If it is E-UTRAN community that the community of basic covering is provided, can use so the Cell Activation(community of X2 mouth to activate); If that basic covering is provided is 3G(The3rd Generation Telecommunication, 3G (Third Generation) Moblie technology) or 2G(The2nd Generation Telecommunication, Generation Mobile Telecommunication System technology) community, need so RIM(RAN(Radio Access Network, Radio Access Network) Information Management, RAN management flow) message process reactivates Hot Spot.

Scene for overlapping covering, after Hot Spot is deactivated, user in its original geographic area covering can provide service by basic coverage cell, there will not be the covering cavity of wireless signal, therefore can not cause user there is no the network coverage and call drop.

2) cell energy-saving under non-overlapped covering (non-overlapping) scene

The cell energy-saving of non-overlapped covering scene has two kinds of situations to need to consider, as shown in Figure 2 A and 2B:

Fig. 2 A is that a plurality of compensation community that belongs to a base station is the scene of a plurality of energy-saving cells compensation, and wherein, energy-saving cell 4,5,6 belongs to different base stations, and compensation community 1,2,3 belongs to same base station;

Fig. 2 B is that the compensation community that belongs to a plurality of different base stations is the scene of a plurality of energy-saving cells compensation, and wherein energy-saving cell 1,2,3 belongs to same base station (they also can belong to different base stations certainly), and compensation community 4,5,6 belongs to different base stations.

3) co-channel interference and ICIC(Inter-Cell Interference Coordination, Inter-Cell Interference Coordination) mechanism

In network, when the covering of co-frequency cell overlaps, can produce very strong homogenous frequency signal and disturb, reduce network performance and user's service quality.In order to address this problem, in LTE and LTE-A system, introduced Inter-Cell Interference Coordination (ICIC) mechanism, wherein a kind of method is time domain (time domain) ICIC, its principle is that subframe (subframe) use between different districts is coordinated in time, and this is called almost blank subframe pattern (Almost Blank Subframe Pattern).Almost blank subframe (ABS) refers on some channel in these subframes of Yi Ge community and reduces, transmitting power not even, another community can be on the channel of these subframes normal transmission, the interference of effect Shi Liangge community in these subframes reduced.

Network (base station) need to be notified the measurement pattern based on ABS to UE by signaling, and to limit the measurement of UE in specific sub-frame, this is called measurement resource limitation, and the pattern information that base station configures to UE is called the subframe pattern of measuring.According to measuring object (as RRM or channel information) difference, measuring object different (Serving cell or adjacent area), base station need to configure different measurement subframe patterns for UE.

In non-overlapped covering scene, also there is no to carry out between complete base station at present the Distributed-solution of energy-saving compensated coordination.

Wherein, while also carrying the ABS information of compensation community application in the compensation success response message that S1 receives, S1 is to S2, when Sn sends community close request message, also need whether to exist in judgement compensation cell list with S2(or ... Sn) with compensation community frequently, and when being judged as while existing, to S2(or ... Sn) in the community close request message sending, also need the ABS information with frequently compensating community application of carrying.

Step 406, S2(or ... Sn) receive after the community turn-off request of S1 transmission, judge whether self can enter power save mode.

If be judged as YES, enter power save mode, to S1, return to community and close successfully response message;

If be judged as NO, to S1, return to community Fail-closed response message.

Concrete, S2(or ... Sn) receive after the community turn-off request of S1 transmission, judging in the list of energy-saving cell has energy-saving cell need to enter power save mode, S2(or ... Sn) according to the actual conditions of self, determine whether to enter power save mode, and when being judged as YES, UE is switched to suitable target compensation community, then enter power save mode, and to S1, return to community and close successfully response message; Otherwise, to S1, return to community Fail-closed response message.In this embodiment, suppose S2 ..., response message is closed successfully in the community that is that Sn returns to S1

Wherein, if S2(or ... Sn) in the community close request message receiving, carry with the ABS information that frequently compensates community application, S2(or ... Sn) determine that self can enter after power save mode, the UE that need to be service according to this ABS information configures suitable measurement subframe pattern, then according to measurement report, UE is switched to suitable target compensation community, last S2(or ... Sn) enter power save mode (ES State), to S1, return to community and close successfully response message.

Step 407, S1 receive the community that in the list of energy-saving cell, every other energy-saving cell is returned and close successfully after response message, enter power save mode.

Concrete, when receiving the community that in the list of energy-saving cell, every other energy-saving cell is returned, S1 closes successfully after response message, determine that in the list of energy-saving cell, every other energy-saving cell can both enter power save mode, definite this energy-saving compensated is coordinated successfully, UE is switched to suitable target compensation community, then enter power save mode.

Wherein, if while carrying ABS information in the compensation success response message that S1 receives, whether S1 also needs to exist with self with compensation community frequently in judgement compensation cell list, and when being judged as YES, the UE that is service according to the ABS information with frequently compensating community application configures suitable measurement subframe pattern, then according to measurement report, UE is switched to suitable target compensation community, and enter power save mode.
