Abstract

The invention discloses a method, a piece of equipment and a system for selecting a service cell and belongs to the field of communication. The method comprises the following steps: strong-interference terminals of one or more corresponding micro base stations among terminals served by a macro base station are determined, wherein the one or more micro base stations are arranged in a macro cell served by the macro base station; and uplink communication of the determined strong-interference terminals is switched to micro cells served by the corresponding micro base stations so as to take the micro cells served by the corresponding micro base stations as uplink service cells of the strong-interference terminals. The strong-interference terminals of the corresponding micro base stations are determined among the terminals served by the macro base station, and the micro cells served by the micro base stations are taken as the uplink service cells of the terminals, which can reduce the transmission power and power consumption of the terminals; and meanwhile, the interference to the micro base station is reduced, and the service performance of the micro base station is improved. In addition, after the terminals are switched to the micro cells, the macro cell can allocate more time-frequency resources to other terminals in the service range, thus improving the service performance of the macro cell.

Embodiment bis-

For heterogeneous network as shown in Figure 4, in macrocell, be distributed with micro-base station 1 and micro-base station 2, the edge distribution of the Microcell 1 that micro-base station 1 is served has the terminal 1,2,3 of macro base station service, these terminals and macro base station distant and with the close together of micro-base station, in the time carrying out uplink communication with macro base station, can form larger interference to micro-base station, cause the lowering service quality of Microcell.In order to address this problem, in conjunction with the content of above-described embodiment one, the embodiment of the present invention provides a kind of method of selecting Serving cell.Referring to Fig. 5, method flow comprises:

501: macro base station sends the uplink SRS configuration information of the terminal of macro base station service to micro-base station, make micro-base station measure the SRS of the terminal of macro base station service according to uplink SRS configuration information, calculate micro-base station according to SRS measurement result and be subject to the interference level of the terminal of macro base station service, and determine according to interference level whether the terminal of macro base station service is the strong jamming terminal of relatively micro-base station.

Wherein, the number of the terminal of macro base station service can be one or more, the number of definite strong jamming terminal can be also one or more, one or more micro-base station for arranging in the macrocell of serving at macro base station, micro-base station, the embodiment of the present invention not number, the definite number of strong jamming terminal and number of micro-base station of the terminal to macro base station service specifically limits, for convenience of explanation, the micro-base station in the present embodiment and subsequent embodiment all represents the micro-base station in the macrocell that macro base station serves.

Further, macro base station can send to micro-base station by the uplink SRS configuration information of all terminals of macro base station service, alternatively, due to the terminal of the distant macro base station service of macro base station, the terminal of the macro base station service nearer with respect to other and macro base station, interference strength to Microcell is larger, thereby there is larger probability to become the strong jamming terminal of micro-base station, therefore, macro base station also can be only sends to micro-base station by the uplink SRS configuration information that is greater than the terminal of the macro base station service of predeterminable range with the distance of macro base station, realize thus by setting predeterminable range and screen and need to determine whether the terminal into the macro base station service of strong jamming terminal in micro-base station, thereby can reduce micro-base station and all determine whether the workload into strong jamming terminal for the terminal of each macro base station service.Wherein, predeterminable range can be selected according to actual conditions, for example, can be chosen to be 1km or 2km etc., and the embodiment of the present invention is not specifically limited the size of predeterminable range.

Particularly, micro-base station is calculated and is subject to the interference level of the terminal of macro base station service in micro-base station according to SRS measurement result, and while determining according to interference level whether the terminal of macro base station service is the strong jamming terminal of relatively micro-base station, the SRS measurement result of the terminal of the macro base station service that micro-base station obtains micro-base station measurement is as interference sections, and the SRS measurement result of micro-base station of measuring of the uplink SRS configuration information of the terminal that micro-base station is served according to micro-base station terminal of serving is as signal transmission part, thereby calculate the ratio of signal transmission part and interference and noise section, obtain Signal to Interference plus Noise Ratio, this Signal to Interference plus Noise Ratio is the interference level that micro-base station is subject to the terminal of macro base station service, by interference level and the first default thresholding comparison setting in advance, if interference level is greater than the first default thresholding, micro-base station determines that the terminal of this macro base station service is the strong jamming terminal of relatively micro-base station, wherein, the first default thresholding can be selected according to actual conditions, for example, can be chosen to be 3db or 5db etc., and the embodiment of the present invention is not specifically limited the size of the first default thresholding.

For instance, in Fig. 4, terminal 1,2,3 is the terminal of macro base station service, and Microcell 1,2 is positioned at the macrocell that macro base station is served, and terminal 1 and terminal 2 are greater than predeterminable range with the distance of macro base station.Micro-base station 1 receives the terminal 1 of macro base station transmission and the SRS configuration information of terminal 2, according to the uplink SRS configuration information difference measuring terminals 1 of the terminal 1 receiving and terminal 2 and the SRS of terminal 2, and calculate micro-base station 1 and be subject to respectively the interference level of terminal 1 and terminal 2 according to SRS measurement result, the interference level of the terminal calculating 1 and terminal 2 is preset to thresholding comparison with first respectively, if the interference level of terminal 1 is greater than the first default thresholding, determine that terminal 1 is the strong jamming terminal of relatively micro-base station 1, if the interference level of terminal 2 is greater than the first default thresholding, determine that terminal 2 is also the strong jamming terminal of relatively micro-base station 1.Micro-base station 2 determines that whether terminal 1 and terminal 2 be that the method for strong jamming terminal of relative micro-base station 2 is identical with micro-base station 1, do not repeat them here.

502: macro base station receives the notice that the strong jamming terminal by definite micro-base station that micro-base station sends is switched, in this notice, carry the mark of strong jamming terminal.

Particularly, the notice that switch strong jamming terminal definite micro-base station by X2 interface micro-base station sends to macro base station, carries the mark of strong jamming terminal in this notice.Wherein, X2 interface is LTE(Long TermEvolution, Long Term Evolution) realize eNB(evolved Node B, evolved base station in network) interface of interconnection.

For this step, if the number of the strong jamming terminal of relatively micro-base station that in step 501, micro-base station is determined is one, in this notice, carry the mark of this strong jamming terminal, if the number of the strong jamming terminal of relatively micro-base station that in step 501, micro-base station is determined is multiple, in this notice, carry the mark of multiple corresponding strong jamming terminals.

For instance, in Fig. 4, if micro-base station 1 determines that strong jamming terminal is terminal 1, in the notice that micro-base station 1 that macro base station receives sends, only carried the mark of this strong jamming terminal 1; If the definite strong jamming terminal in micro-base station 1 is terminal 1 and terminal 2, in the notice that micro-base station 1 that macro base station receives sends, carry the mark of strong jamming terminal 1 and terminal 2.

503: macro base station is determined the strong jamming terminal of relatively micro-base station according to the mark of the strong jamming terminal of carrying in notice.

It should be noted that, if the number of the micro-base station in above-mentioned steps 501 is multiple, after the uplink SRS configuration information of the terminal that the each micro-base station in multiple micro-base stations is served at the macro base station that receives macro base station transmission, all need to carry out respectively and determine whether the terminal of macro base station service is the process of the strong jamming terminal of relative this micro-base station, the notice that macro base station receives in this step can be the notice of multiple micro-base stations transmissions, determines respectively the strong jamming terminal of each micro-base station relatively according to the mark of the strong jamming terminal of carrying in each notice.

For instance, in Fig. 4, macro base station receives after the notice that micro-base station 1 and micro-base station 2 send, and the strong jamming terminal 1 of carrying in the notice sending according to micro-base station 1 determines with the mark of terminal 2 the strong jamming terminal that terminal 1 is relative micro-base station 1 with 2; The strong jamming terminal 1 of carrying in the notice sending according to micro-base station 2 determines with the mark of terminal 2 the strong jamming terminal that terminal 1 is relative micro-base station 2 with terminal 2.

504: the uplink communication of definite strong jamming terminal is switched to the Microcell that corresponding micro-base station is served by macro base station, using Microcell that micro-base station of correspondence is served as the uplink service cell of strong jamming terminal.

Particularly, the uplink communication of definite strong jamming terminal is switched to the Microcell that corresponding micro-base station is served by macro base station, can include but not limited to following two kinds of methods using the Microcell that micro-base station of correspondence is served as the uplink service cell of strong jamming terminal:

Method one: macro base station selects to be subject to strong jamming terminal to disturb maximum micro-base station in micro-base station, the uplink communication of strong jamming terminal is switched to the Microcell that is subject to strong jamming terminal to disturb maximum micro-base station to serve, using the uplink service cell as strong jamming terminal by the Microcell that served by the maximum micro-base station of strong jamming terminal interference.

For this method, when macro base station selects to be subject to strong jamming terminal to disturb maximum micro-base station in micro-base station, if strong jamming terminal is the strong jamming terminal of a relative micro-base station, macro base station determines that this micro-base station is the micro-base station that is subject to the interference maximum of strong jamming terminal; If strong jamming terminal is the strong jamming terminal of relatively multiple micro-base stations, macro base station determines that each micro-base station is subject to the interference size of strong jamming terminal, selects to be subject to strong jamming terminal to disturb maximum micro-base station from multiple micro-base stations.

Particularly, when macro base station selects to be subject to strong jamming terminal to disturb maximum micro-base station in micro-base station, can select according to the interference level of the strong jamming terminal of each micro-base station measurement, for example, the interference level of the strong jamming terminal calculating according to SRS measurement result from each micro-base station, select micro-base station of interference level maximum finally to determine as macro base station micro-base station that strong jamming terminal is switched to, the interference level of the strong jamming terminal of this micro-base station measurement can be carried in the notice that the strong jamming terminal by definite that in step 502, micro-base station sends switches, thereby macro base station receives after this notice, can be according to the interference level of the strong jamming terminal of carrying in this notice, thereby in micro-base station, select to be subject to strong jamming terminal to disturb maximum micro-base station.In addition, also have other in micro-base station, to select to be subject to strong jamming terminal to disturb the method for maximum micro-base station, for example, macro base station can send the message that triggers the RSRP that measures micro-base station to strong jamming terminal, by this strong jamming terminal, the RSRP of each micro-base station is measured, and the RSRP measuring is returned to macro base station, make RSRP that macro base station measures according to this strong jamming terminal and the transmitting power of this strong jamming terminal, determine that micro-base station is subject to the interference size of strong jamming terminal, thereby in micro-base station, select to be subject to strong jamming terminal to disturb maximum micro-base station.Which kind of specifically adopts select the mode of micro-base station, and the embodiment of the present invention is not specifically limited this.

For instance, in Fig. 4, if strong jamming terminal 1 is only the strong jamming terminal of micro-base station 1, macro base station determines that micro-base station 1 is subject to the interference maximum of strong jamming terminal 1, the uplink communication of strong jamming terminal 1 is switched to the Microcell 1 that micro-base station 1 is served, using Microcell 1 that micro-base station 1 is served as the uplink service cell of strong jamming terminal 1.If strong jamming terminal 1 is the strong jamming terminal of micro-base station 1, again the strong jamming terminal of micro-base station 2 simultaneously, the interference level of the strong jamming terminal 1 of carrying in the notice that the interference level of the strong jamming terminal 1 of carrying in the notice that micro-base station 1 that macro base station can obtain from step 502 sends and micro-base station 2 send, if the interference level of the strong jamming terminal 1 of carrying in the notice that micro-base station 2 sends is greater than the interference level of the strong jamming terminal 1 of carrying in the notice that micro-base station 1 sends, the uplink communication of strong jamming terminal 1 is switched to the Microcell 2 that micro-base station 2 is served by macro base station, to be subject to strong jamming terminal 1 to disturb the community as the up service of strong jamming terminal 1, Microcell 2 that maximum micro-base station 2 served this.

Alternatively, macro base station is disturbed maximum micro-base station by strong jamming terminal except selecting in micro-base station in the manner described above, can also have additive method is that definite strong jamming terminal is selected micro-base station, thereby the uplink communication of strong jamming terminal is switched to the Microcell that this micro-base station is served, for example, macro base station can also be selected a micro-base station in micro-base station corresponding in definite strong jamming terminal at random, thereby the uplink communication of this strong jamming terminal is switched to the Microcell that this micro-base station is served.For specifically selecting which kind of method to select micro-base station for strong jamming terminal, thereby the uplink communication of strong jamming terminal is switched to the Microcell that micro-base station of this selection is served, the embodiment of the present invention is not specifically limited this.

Method two: macro base station sends measures message to strong jamming terminal, makes strong jamming terminal measure the RSRP of micro-base station, and select micro-base station of RSRP maximum in micro-base station, and the cell ID of micro-base station of RSRP maximum is sent to macro base station; Macro base station receives the cell ID of micro-base station of the RSRP maximum of strong jamming terminal transmission, according to the cell ID of micro-base station of RSRP maximum, the uplink communication of strong jamming terminal is switched to the Microcell that micro-base station of RSRP maximum is served, using Microcell that micro-base station of this RSRP maximum is served as the uplink service cell of strong jamming terminal.

In general the micro-base station that, is subject to the interference maximum of strong jamming terminal in method one is also micro-base station of RSRP maximum in method two.

For this method, strong jamming terminal is measured the RSRP of micro-base station, and select micro-base station of RSRP maximum in micro-base station time, if strong jamming terminal is the strong jamming terminal of a relative micro-base station, strong jamming terminal is measured the RSRP of this micro-base station, and selects micro-base station that this micro-base station is RSRP maximum; If when strong jamming terminal is the strong jamming terminal of relatively multiple micro-base stations, strong jamming terminal is measured the RSRP of multiple micro-base stations, and in multiple micro-base stations, selects micro-base station of RSRP maximum.

For instance, in Fig. 4, if strong jamming terminal 1 is only the strong jamming terminal of micro-base station 1, macro base station sends measures message to strong jamming terminal 1, make strong jamming terminal 1 measure the RSRP of micro-base station 1, determine that the RSRP of micro-base station 1, for maximum, sends to macro base station by the cell ID of micro-base station 1 of this RSRP maximum; Macro base station receives after the cell ID of micro-base station 1 of the RSRP maximum that strong jamming terminal 1 sends, the uplink communication of strong jamming terminal 1 is switched to the Microcell 1 that micro-base station 1 is served, using Microcell 1 that micro-base station 1 of this RSRP maximum is served as the uplink service cell of strong jamming terminal 1.If strong jamming terminal 1 is the strong jamming terminal of micro-base station 1, again the strong jamming terminal of micro-base station 2 simultaneously, macro base station sends measures message to strong jamming terminal 1, make strong jamming terminal 1 measure respectively the RSRP of micro-base station 1 and micro-base station 2, if the RSRP of micro-base station 2 that strong jamming terminal 1 measures is greater than the RSRP of micro-base station 1, the cell ID of micro-base station 2 of RSRP maximum is sent to macro base station by strong jamming terminal 1; Macro base station receives after the cell ID of micro-base station 2 of the RSRP maximum that strong jamming terminal 1 sends, uplink communication is switched to the Microcell 2 that micro-base station 2 is served, using Microcell 2 that micro-base station 2 of this RSRP maximum is served as the uplink service cell of strong jamming terminal 1.

Embodiment tri-

For heterogeneous network as shown in Figure 4, in macrocell, be distributed with micro-base station 1 and micro-base station 2, the edge distribution of the Microcell 1 that micro-base station 1 is served has the terminal 1,2,3 of macro base station service, these terminals and macro base station distant and with the close together of micro-base station, in the time carrying out uplink communication with macro base station, can form larger interference to micro-base station, cause the lowering service quality of Microcell.In order to address this problem, in conjunction with the content of above-described embodiment one, the embodiment of the present invention provides a kind of method of selecting Serving cell.Referring to Fig. 6, method flow comprises:

601: the RSRP of micro-base station that the terminal of the macro base station service that the terminal of macro base station reception macro base station service sends measures.

Wherein, the number of the terminal of macro base station service can be one or more, one or more micro-base station for arranging in the macrocell of serving at macro base station, micro-base station, the embodiment of the present invention not number of the terminal to macro base station service and the number of micro-base station specifically limits, for convenience of explanation, the micro-base station in the present embodiment and subsequent embodiment all represents the micro-base station in the macrocell that macro base station serves.

Further, macro base station receives the RSRP of micro-base station that the RSRP of micro-base station that the terminal of the macro base station service that the terminal of macro base station service sends measures can measure for all terminals of macro base station service, alternatively, due to the terminal of the distant macro base station service of macro base station, the terminal of the macro base station service nearer with respect to other and macro base station, interference strength to Microcell is larger, thereby there is larger probability to become the strong jamming terminal of micro-base station, therefore, the RSRP of micro-base station that the terminal of the macro base station service that the terminal of macro base station reception macro base station service sends measures can be also the RSRP that is greater than micro-base station of the terminal measurement of the macro base station service of predeterminable range with the distance of macro base station, realize thus the terminal of screening the macro base station service of the RSRP that needs micro-base station that reporting measurement obtains by setting predeterminable range.Wherein, predeterminable range can be selected according to actual conditions, for example, can be chosen to be 1km or 2km etc., and the embodiment of the present invention is not specifically limited the size of predeterminable range.

It should be noted that, the mode that the terminal of triggering macro base station service is measured the RSRP of micro-base station includes but not limited to that macro base station sends and triggers the message of measuring to the terminal of its service, in addition, can also there be other triggering modes, for example, automatically triggered and measure operation according to predetermined period by terminal, specifically adopt which kind of triggering mode, the present embodiment is not specifically limited this.

For instance, in Fig. 4, terminal 1,2,3 is the terminal of macro base station service, Microcell 1 and Microcell 2 are positioned at the macrocell that macro base station is served, terminal 1 and terminal 2 are greater than predeterminable range with the distance of macro base station, therefore, terminal 1 receives after the message of triggering measurement of macro base station transmission, measure respectively the RSRP of micro-base station 1 and the RSRP of micro-base station 2, and the RSRP of the RSRP of the micro-base station 1 measuring and micro-base station 2 is sent to macro base station, macro base station gets the RSRP of micro-base station 1 and the RSRP of micro-base station 2 that terminal 1 measures.The RSRP of micro-base station 1 that macro base station acquisition terminal 2 measures is identical with said method with the method for the RSRP of micro-base station 2, does not repeat them here.

602: the strong jamming terminal of uplink transmission power definite relative micro-base station in the terminal of macro base station service of the RSRP of micro-base station that macro base station sends according to the terminal of macro base station service and the terminal of macro base station service.

Wherein, the number of definite strong jamming terminal can be one or more, and the embodiment of the present invention does not specifically limit the number of definite strong jamming terminal.

For this step, the uplink transmission power of the terminal of macro base station service is that macro base station obtains according to the uplink transmission power surplus of the terminal of macro base station service and uplink transmission power maximum value calculation, wherein, the uplink transmission power surplus of the terminal of macro base station service can be that the uplink transmission power surplus of self is sent to macro base station by the terminal of macro base station service, the maximum of the uplink transmission power of the terminal of macro base station service can be that macro base station is known, in addition, macro base station can also obtain uplink transmission power surplus and the uplink transmission power maximum of the terminal of macro base station service by other means, the embodiment of the present invention does not specifically limit at this.

Particularly, when the uplink transmission power of the RSRP of micro-base station that macro base station sends according to the terminal of macro base station service and the terminal of macro base station service is determined the strong jamming terminal of relative micro-base station in the terminal of macro base station service, the RSRP of micro-base station that macro base station sends the terminal of macro base station service and the second default thresholding comparison setting in advance, by the uplink transmission power of the terminal of macro base station service and the 3rd default thresholding comparison setting in advance, if the RSRP that the terminal of macro base station service sends is greater than the second default thresholding, and the uplink transmission power of the terminal of macro base station service is greater than the 3rd default thresholding, the terminal of determining this macro base station service is the strong jamming terminal of relatively micro-base station.Wherein, the size of the second default thresholding and the 3rd default thresholding can be set according to actual conditions, for example, the second thresholding can be 3dBm or 5dBm, the 3rd default thresholding can be 5dBm or 10dBm etc., and the embodiment of the present invention is not specifically limited the size of the second default thresholding and the 3rd default thresholding.

For instance, in Fig. 4, the RSRP of micro-base station 1 that the terminal 1 that macro base station receiving terminal 1 sends is measured and the RSRP of micro-base station 2, also receive the uplink transmission power surplus of the terminal 1 that terminal 1 sends, the RSRP of micro-base station 1 that macro base station measures terminal 1 and the second default thresholding comparison, and, obtain the uplink transmission power of terminal 1 according to the uplink transmission power surplus of terminal 1 and uplink transmission power maximum value calculation, by the uplink transmission power of terminal 1 and the 3rd default thresholding comparison, if the RSRP of micro-base station 1 that terminal 1 measures is greater than the uplink transmission power of the second default thresholding and terminal 1 and is greater than the 3rd default thresholding, determine the strong jamming terminal that this terminal 1 is relatively micro-base station 1, the RSRP of micro-base station 2 that macro base station also measures terminal 1 and the second default thresholding comparison, and by the uplink transmission power of terminal 1 and the 3rd default thresholding comparison, if the RSRP of micro-base station 2 that terminal 1 measures is greater than the uplink transmission power of the second default thresholding and terminal 1 and is greater than the 3rd default thresholding, determine that terminal 1 is the strong jamming terminal of relatively micro-base station 2.Correspondingly, macro base station determines that whether terminal 2 is that the method for strong jamming terminal of micro-base station 1 and micro-base station 2 is identical with the method for definite terminal 1, does not repeat them here.

603: the uplink communication of definite strong jamming terminal is switched to the Microcell that corresponding micro-base station is served by macro base station, using Microcell that micro-base station of correspondence is served as the uplink service cell of strong jamming terminal.

The specific implementation of this step is identical with the implementation of step 504 in above-described embodiment two, specifically, referring to the step 504 in above-described embodiment two, repeats no more herein.
