Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

In heterogeneous network, there is macro base station and micro-base station simultaneously, the community that macro base station covers is called macrocell, and the community that micro-base station covers is called Microcell.In heterogeneous network, UE may be in three kinds of network coverage situations: first is that UE is in soft handover, and usings macrocell as Serving cell; Second UE be near soft handover area, and using macrocell as Serving cell; The 3rd be UE near soft handover area, and using Microcell as Serving cell.In the third situation, when Microcell, the place load of micro-base station is lighter, may allow the UE that Qie Yi Microcell, close soft handover area is Serving cell to send larger ascending power, this can cause the strong uplink interference of these UE to macro base station.For this problem, following examples of the present invention have provided solution.For convenience of description, in the following embodiment of the present invention, by using community, place, micro-base station as the UE of Serving cell referred to as a UE.

The flow chart of a kind of disturbance restraining method that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the method for the present embodiment comprises:

Step 101, obtain the channel parameter of all UE in the Serving cell that resides in micro-base station, described UE is in CELL-DCH state, or in CELL_FACH state.

Those skilled in the art should know, UE is generally in two states: idle pulley (Idle) and connection mode, UE comprises again following state under connection mode: CELL_DCH state, CELL_FACH state, CELL_PCH state, URA_PCH state, wherein, CELL_DCH state has following feature: 1, in uplink and downlink, to UE, distributed a DPCH, 2, according to the current active set of UE, can know the community at UE place, 3, UE can use dedicated transmission channel descending/combination of up shared transmission channel or these transmission channels; UE enters CELL_DCH state following 2 kinds of methods: (1) UE RRC connection under idle pulley is based upon on special-purpose trade so UE enters CELL_DCH state from idle pulley, and (2) UE is used dedicated transmission channel UE to enter into CELL_DCH state from CELL_FACH state after using Common transport channel to switch by channel under CELL_FACH state; CELL_FACH state has following feature: 1, to UE, do not distribute dedicated transmission channel, 2, UE monitors a descending FACH channel continuously, 3, for UE distributed the uplink common channel of an acquiescence or up shared transmission channel for example RACH enable to use in any time in access procedure, 4, the position of UE is being specially the community of reporting when UE is the last initiates cell update known to cell-level is UTRAN; Action below the sub-state UE of CELL_FACH carries out: 1, monitor a FACH, 2, monitor the BCH transmission channel decode system information message of current service cell, while 3, becoming another UTRA community in community, initiate a cell updating course, 4, except non-selection Liao Yigexin community otherwise use the C-RNTI distribute in current area as the UE sign on Common transport channel, 5, at RACH, upload and send upstream control signaling and small data packets; Under CELL_FACH state, if data service is not activated in following period of time, UE will enter CELL_PCH state to reduce the loss of power, and when temporarily departing from CELL_PCH state, UE carries out cell update, if UE and network side are all without transfer of data demand after renewal completes, it will return to CELL_PCH, be more than the common practise of this area, repeat no more.

Step 102, according to the channel parameter of UE, respectively the up channel of each UE is monitored, obtain the uplink interference amount of UE to macro base station.

Step 103, the uplink interference amount according to UE to macro base station, the object UE of definite transmitted power to be reduced from described UE.

Step 104, by object UE, notify micro-base station, so that micro-base station reduces the transmitted power of object UE.

In all UE in residing in the Serving cell of micro-base station, in Cell_DCH state or the UE in CELL_FACH state, just can macro base station be produced and be disturbed, thus the UE described in the present embodiment refers in the Serving cell that resides in micro-base station and in Cell_DCH state or the UE of CELL_FACH state.In the present embodiment, macro base station only to reside in the Serving cell of micro-base station and in Cell_DCH state or the UE of CELL_FACH state process, rather than all UE are processed, be conducive to alleviate the burden of macro base station.

In the present embodiment, the channel parameter of UE mainly refers to that macro base station monitors required information to the up channel of UE, at least comprises that the sign (ID) of UE is, the channel code that the scrambler that UE is used and UE are used.Optionally, the channel parameter of UE can also comprise: the modulation system that the ID of the resident Microcell of UE, UE are used etc.

After macro base station obtains the channel parameter in the Serving cell that resides in micro-base station and in CELL-DCH state or all UE in CELL_FACH state, according to the channel parameter of each UE, respectively the up channel of each UE is monitored.Concrete, macro base station can be determined UE according to the ID of the ID of UE and/or UE persistent district, the information such as the scrambler then using according to UE, channel code detect the up transmitted signal that whether comprises this UE in the signal receiving.Optionally, if the channel parameter of UE also comprises the modulation system that UE is used, macro base station can also comprise this information of modulation system that UE is used according to channel parameter, further determines the up transmitted signal that comprises UE in the signal receiving.Then, macro base station calculates the uplink interference amount of each UE to macro base station that obtain.Concrete, macro base station comprises after the up transmitted signal of UE in received signal being detected, can be using the received signal power of the up transmitted signal of UE as this UE the uplink interference amount to macro base station.

Obtain each UE to the uplink interference amount of macro base station after, macro base station just can judge the annoyance level of each UE to macro base station, and each UE is compared the uplink interference amount of macro base station and default interference volume thresholding; If UE is greater than default interference volume thresholding to the uplink interference amount of macro base station, illustrate that this UE is comparatively serious to the interference of macro base station, need to reduce the transmitted power of this UE; If this UE is less than or equal to default interference volume thresholding to the uplink interference amount of macro base station, illustrate that this UE is not very serious to the interference of macro base station, the transmitted power of this UE can reduce.Based on this, macro base station can be greater than the UE of default interference volume thresholding as the object UE of transmitted power to be reduced to the uplink interference amount of macro base station using all in CELL-DCH state or the UE in CELL_FACH state.In this explanation, the object UE here can be one, can be also a plurality of.The concrete numerical value of the default interference volume thresholding here can be determined according to practical application scene, by being set, interference volume thresholding can only reduce the transmitted power of in all UE, macro base station being disturbed comparatively serious part UE, be conducive to alleviate the processing load of macro base station and micro-base station on the one hand, be conducive on the other hand make full use of ascending resource.

Then, macro base station sends to micro-base station by determined object UE, so that micro-base station reduces the transmitted power of object UE.

From above-mentioned, in the present embodiment, macro base station is according to residing in the Serving cell of micro-base station and the channel parameter in CELL-DCH state or the UE in CELL_FACH state, respectively the up channel of each UE is monitored, determine the interference volume of each UE to macro station, and therefrom determine the object UE that need to reduce transmitted power, then notify micro-base station to reduce the transmitted power of object UE, reduced on the one hand the interference to macro base station, on the other hand owing to only reducing transmitted power to being necessary to reduce the UE of transmitted power, rather than directly reduce the RTWP of micro-base station, be conducive to make full use of ascending resource, reduce the waste of ascending resource.

The flow chart of the another kind of disturbance restraining method that Fig. 2 provides for the embodiment of the present invention.As shown in Figure 2, the method for the present embodiment comprises:

Step 201, macro base station are to the transmitting channel parameter acquiring request of micro-base station.

Step 202, macro base station receive micro-base station channel parameter that the request of obtaining is returned according to this channel parameter and obtain response, and this channel parameter obtains response and carries the channel parameter in the Serving cell that resides in micro-base station and in CELL-DCH state or the UE in CELL_FACH state.

In the present embodiment, described UE refers in the Serving cell that resides in micro-base station and in CELL-DCH state or the UE in CELL_FACH state.The channel parameter of described UE at least comprises: the channel code that the scrambler that the sign of UE (ID), UE are used and UE are used.Optionally, the channel parameter of UE can also comprise: the modulation system that the ID of the resident Microcell of UE, UE are used etc.

Optionally, macro base station can be when the RTWP that determines macro base station be greater than default power threshold, and to the transmitting channel parameter acquiring request of micro-base station, the channel parameter that then receives the transmission of micro-base station obtains response.Wherein, default power threshold configures when network initial deployment, for weighing the degree of the ascending load of macro base station.The present embodiment does not limit the numerical value of default power threshold, for example can the definition to this power threshold with reference to relevant agreement or standard.It is heavier that the RTWP of macro base station is greater than the load of default power threshold explanation macro base station, now poor to the tolerance of the interference that resides in the Serving cell of micro-base station and bring in CELL-DCH state or the UE in CELL_FACH state, need to disturb inhibition.Concrete, macro base station can be measured the RTWP of macro base station, and whether the RTWP that judgement measures is greater than default power threshold, when judging RTWP and be greater than default power threshold, when needs suppress to disturb, by Iub interface, to the transmitting channel parameter acquiring request of micro-base station, acquisition request resides in the Serving cell of micro-base station and the channel parameter in CELL-DCH state or the UE in CELL_FACH state, can reduce like this mutual between macro base station and micro-base station, be conducive to economize on resources.If the RTWP of macro base station is less than or equal to default power threshold, the load that macro base station is described is lighter, the interference that can tolerate in the Serving cell that resides in micro-base station and bring in CELL-DCH state or the UE in CELL_FACH state, so can suppress the transmitted power of any UE, be conducive to improve the utilance of ascending resource.

Step 203, macro base station, according to the channel parameter of each UE, are monitored the up channel of each UE respectively, obtain the uplink interference amount of UE to macro base station.

Step 204, macro base station be the uplink interference amount to macro base station according to UE, determines the object UE of transmitted power to be reduced from all UE.

Step 205, macro base station are notified micro-base station by object UE, so that micro-base station reduces the transmitted power of object UE.

Above-mentioned steps 203-step 205 can, referring to the description of above-mentioned steps 102-104, not repeat them here.

Optionally, macro base station is notified micro-base station by object UE, so that reducing a kind of execution mode of the transmitted power of object UE, micro-base station comprises: macro base station can send to micro-base station by the sign of object UE, make micro-base station according to the sign of object UE, from reside in all UE the Serving cell of micro-base station, determine object UE, and reduce the transmitted power of object UE.

Optionally, macro base station sends to micro-base station by the sign of object UE, make micro-base station according to the sign of object UE, from reside in all UE the Serving cell of micro-base station, determine object UE, and a kind of execution mode that reduces the transmitted power of object UE comprises: macro base station is after determining object UE, the sign of object UE and object UE are sent to micro-base station to the uplink interference amount of macro base station, so that micro-base station is according to the sign of object UE, in all UE from the Serving cell of resident micro-base station, determine object UE, according to object UE, the uplink interference amount of macro base station is determined to transmitted power reducing amount, and according to the transmitted power of described transmitted power reducing amount reduction object UE.

Wherein, macro base station can be two independently processes to micro-base station transmission object UE to the process of the uplink interference amount of macro base station to process and the macro base station of the sign of micro-base station transmission object UE.Comparatively preferred, macro base station can send to micro-base station to the uplink interference amount of macro base station by the sign of object UE and object UE in a process simultaneously.
