Detailed description of the invention
Describe embodiments of the present invention in detail below in conjunction with graphic and embodiment, thereby the present invention how application technology means are solved technical problem and reaches the process that realizes of technology effect and can fully understand and implement according to this.
Below as it is shown in figure 1, provide embodiments of the invention one to set forth the different system adjacent cell acquisition methods in a kind of LTE community, as described method includes:
Step S101: judge whether described LTE community and different system cell exist co-sited cell, if there is co-sited cell, entering step 102, if being absent from co-sited cell, entering step 103.
Community is the basic network element in mobile wireless network, and it is under the jurisdiction of the logical block under physical entity base station, and its main base attribute has:
Adjacent area, different system adjacent cell (2G��3G, 2G��4G, 3G��2G, 3G��4G, 4G��2G, 4G��3G) in geographic logitude residing for cell name, community standard, community, the geographic latitude residing for community, community deflection, system.
Wherein adjacent area namely original adjacent area in system, this information to configure when opening base station, once network namely comprise neighboring BS information in system.
Described LTE community is 4G standard community, therefore, it is determined that whether itself and different system cell exist the situation of co-sited, namely judges whether 4G community and 2G and 3G community have co-sited situation.
According to described LTE community and the latitude and longitude information in the attribute information of described different system cell, it is determined that two community distance difference, when described two community distance difference are less than particular value, it is determined that two community co-sited. Distance difference can set according to practical situation, belongs to empirical value commonly used in the trade. Under normal circumstances it is believed that when community distance is less than 50 meters, it is determined that two communities are co-sited cell.
Step S102: obtain the co-sited cell of LTE community and different system cell, obtains the different system adjacent cell in described LTE community according to original adjacent area, community in the same direction of described co-sited cell, the dependency of original adjacent area, described community in the same direction, described co-sited cell with LTE minizone distance range.
Determine that deflection difference community in particular range is for community in the same direction according to the deflection information in described co-sited cell attribute information. Deflection difference can set according to practical situation, belongs to empirical value commonly used in the trade. Such as it is believed that community angular difference value in direction under the premise of co-sited judges that two communities are as community in the same direction in (-n ��, n ��) scope.
According to the neighboring BS information in the described information of cell attribute in the same direction obtain described in original adjacent area of community in the same direction. One of original adjacent area attribute belonging to community of community, therefore can directly obtain from cell attribute.
Step S103: determine different system peripheral cell with described LTE minizone distance according to default, the deflection in conjunction with described LTE community and described different system peripheral cell obtains the different system adjacent cell in described LTE community with distance relation.
The present invention co-sited relation according to LTE community Yu different system cell, set different adjacent area acquisition methods, if LTE community and different system cell have co-sited relation, the different system adjacent cell of original adjacent area that the likely different system cell of co-sited is then described and the Yi Shi LTE community, community with different system cell with high correlation, therefore carries out the mode that these parameters and distance combine the different system adjacent cell in LTE community and obtains; When LTE community and different system cell are absent from co-sited relation, then limit, only by the original attribute (deflection) in community and distance, the different system adjacent cell obtaining LTE community.

Step S203: obtain original adjacent area set X2 of community in the same direction in described co-sited cell set X1.
Community can be judged by deflection in the same direction, determines that original adjacent area set of community in the same direction in X1 set is added into set X2. one by one
Step S204: gather X2 according to described original adjacent area and obtain and described set X2 high correlation set of cells X3.
Obtain main Serving cell level and adjacent cell level according to the nearby region measurement data NCS in the attribute information of described set X2 small area, determine the dependency of described set X2 small area according to described main Serving cell level and adjacent cell level difference value absolute value.
NCS full name: NeighborCellSupport, utilizes the mobile phone of user to remove to measure the signal intensity measuring frequency of definition, and the measurement frequency defined can be the frequency of non-neighbor cell. These measurement data directly or indirectly can also obtain from telecommunication system.
Dependency refers to, main Serving cell in the measurement report of adjacent cell, the measurement report number accounting of main plot. The effective measurement report number accounting referring to main plot of dependency herein. The definition effectively measured is | main Serving cell level-adjacent cell level | < 6DB. The judgement of dependency can be completed by NCS data.
Step S205: obtain described set X2 and X3 in the set of cells X4 in the specific distance range of described LTE minizone.
