The embodiment of the present invention provides a kind of method adjusting cell coverage area, controls base station centered by the executive agent of the method.As shown in Figure 2, the method is as described below.
200, control base station, center generates the first request message of adjustment coverage.
Wherein, described first request message comprises the instruction that amendment coverage increases or coverage reduces, and/or, coverage information; Described coverage information comprises pilot spreading code or index or port numbers, and/or, antenna directional angle or horizontal angle or phase angle or transmitting power.
Control base station, center is equivalent to baseband processing unit BBU, for completing the Base-Band Processing function of Uu interface, such as encode, multiplexing, modulation and the function such as spread spectrum, and the IUB interface function of RNC, signaling process, local and remote Operation and Maintenance function, and the Working Status Monitoring of base station system and warning information reporting functions.
201, control base station, described center sends to the first launch point of first class services community the first request message adjusting coverage, second launch point of presence service second community in the launch point managed under control base station, described center, described second community has identical cell ID and identical frequency with described first community.
When the first community is identical with the second cell ID, Shi Yige community in logic, the community under control base station, center, but in order to allow UE can correct demodulating data, some additional information can be increased and allow UE can identify different ports.Such as increase with pilot tone, send together with data in time having data to send, when there is no data, would not send, or the spreading code of different dominant pilots.Make it possible to UE to identify, and report is to the launch point of correspondence.
The embodiment of the present invention provides a kind of method adjusting picocell coverage area, by when the first community is identical with the second cell ID, can increases some additional information and allow UE can identify different ports in the first request message generated.Such as increase with pilot tone, send together with data in time having data to send, when there is no data, would not send, or the spreading code of different dominant pilots.Make it possible to UE to identify, and report is to the launch point of correspondence, makes the present invention can control the coverage of Microcell neatly, thus saving resource and reduce interference.
The embodiment of the present invention provides a kind of method adjusting cell coverage area, controls base station centered by the executive agent of the method.As shown in Figure 3, the method is as described below.
300, control base station, center generates the first request message of adjustment coverage.
Described first request message comprises the instruction that amendment coverage increases or coverage reduces, and/or, coverage information; Described coverage information comprises pilot spreading code or index or port numbers, and/or, antenna directional angle or horizontal angle or phase angle or transmitting power.
301, control base station, center sends to the first launch point of first class services community the first request message adjusting coverage, second launch point of presence service second community in the launch point managed under control base station, described center, described second community has identical cell ID and identical frequency with described first community.
Optionally, the first community is Microcell, and the second community is Microcell or macrocell.
When the burden of community changes, the burden of such as community or when alleviating, needs to be judged by the loading condition of control base station, center to each launch point under its management, and determines the Microcell that needs to carry out coverage adjustment; And according to the bearing capacity of control base station, center to each launch point under its management, generate described first request message of adjustment coverage, then the first request message of adjustment coverage is sent to the launch point belonging to this Microcell, so that the launch point belonging to this Microcell adjusts its coverage, with saving resource, avoid the wasting of resources.
Optionally, can obtain the bearing capacity of all base stations of its management due to control base station, center, therefore control base station in center is according to the described bearing capacity of all base stations, and described first launch point of determining to serve described first community needs to adjust coverage.Bearing capacity can be determined according to the number of users in community or load information or interference value.
Such as, number of users in described first community is greater than first threshold, or when described second community is macrocell, when number of users in described second community is greater than described first threshold, control base station, described center determines that described first launch point of serving described first community needs coverage to increase.
When the number of users in described first community is less than Second Threshold, or the interference value of described first community measured is greater than the 3rd threshold value, or, when described second community is macrocell, number of users in described second community is less than Second Threshold, or when the interference value of described second community measured is greater than the 3rd threshold value, control base station, described center determines that described first launch point of serving described first community needs coverage to reduce.
Optionally, first threshold is the maximum of intra-cell users number, namely when the number of users in community exceedes first threshold, then illustrate that number of users increases, then beyond the ability of launch point of this community of service, the terminal now having certain customers cannot normal talking or cannot perform other operations.Wherein for different communities, first threshold also can be different.Such as, can serve at most 100 users in the A of community, then first threshold can be set to 100; Can serve at most 10 users in the B of community, then first threshold can be set to 10.
Second Threshold is the minimum value of number of users, when the number of users namely in community is lower than Second Threshold, then illustrates that number of users decreases, and in order to saving resource, needs to reduce the coverage of Microcell.Wherein for different communities, Second Threshold also can be different.Such as, minimumly in the A of community can serve 40 users, then Second Threshold can be set to 40; Minimumly in the B of community can serve 5 users, then Second Threshold can be set to 5.
Optionally, the 3rd threshold value is the interference threshold arranged, and when the interference between community is greater than the 3rd threshold value, then needs the coverage reducing Microcell to reduce interference.
Wherein, control base station in center can receive the bearing capacity of all launch points of the described center control BTS management of the RNC transmission belonging to control base station, described center; Or control base station, described center obtains the bearing capacity of all launch points of its management in this locality stores, and preserves the bearing capacity of all launch points of its management in control base station, described center.
Because described first community and described second community have identical cell ID and identical frequency, first community and the second community are identical community in logic, therefore the coverage information that the first request message generated comprises can be the information of differentiation first community and the second community, it comprises pilot spreading code or index or port numbers, and/or, antenna directional angle or horizontal angle or phase angle or transmitting power.
Further alternative, control base station, center to first class services community first launch point send adjustment coverage the first request message time can comprise following several situation.
