Step 103, according to the cell type of candidate adjacent, the priority of candidate adjacent is set, and according to candidate adjacent
Priority configures the neighboring cell list of this cell.
Flow according to the method described above, not only may be implemented neighboring cell list configuration can also according to the method described above flow to
The neighboring cell list of configuration optimizes.Even if practical multistage network topological structure can be according to network topology change if changing
The topology location of candidate adjacent optimizes configured adjacent area afterwards.The above method flow of the present invention is not limited to 4G networks, right
It is also still applicable in GSM, UTMS, TD-SCDMA, WCDMA network.
Before step 101, base station is base station jurisdiction district Configuration network topological parameter, and network topology parameters are configured extremely
In a few cell parameter, for characterizing topology location of the cell in multistage network.Cell parameter, such as CGI (Cell
Global Identitier, Cell Global Identification), LAI (Location Area Identification, position area mark
Know), SAI (Service Area Identifier, Service Area Identifier), LAC (Location Area Code, the band of position
Code), LAC＆Cell ID (Cell Identification, cell ID) etc. may serve to Configuration network topological parameter, example
Some or all of cell ID Cell ID are such as stored as network topology parameters.Base station is by configuring the network topology of cell
Parameter carries out the simpler easily realization of neighbor cell configuration based on network topology parameters.Base station voluntarily configures and the neighbour of base station maintenance cell
Area's list, Adapted for Network topology and its variation, meet gravity treatment/switching demand of cell in practical multistage network.
In multistage network, the connection type of cell own base station and core net is divided into：It directly establishes and connect with core net
Macro base station；The small cell of connection are established by level-one centralized device and core net；By multistage centralized device with
Core net establishes the small cell of connection.
Based on three of the above connection type, when base station is base station jurisdiction district Configuration network topological parameter, it is preferred that with core
Heart net directly establishes the configuration of the network topology parameters of the macro base station cell of connection, is set by one or more levels centralization with any
The configuration of network topology parameters of cell under the standby small base station for establishing connection from core net is different.Specifically, the macro base of configuration
In the network topology parameters for cell of standing, the network topology parameters of any two macro base station cells are different；It is connected with centralized device
In the network topology parameters of the cell of small base station configuration, it is preferred that the network topology parameters of the cell under same centralized device
It is identical；The network topology parameters of cell under the different centralized devices of same stages are different；Under centralized device not at the same level
The network topology parameters of cell are different.In order to make the subzone network topological parameter phase under the centralized device there are relationship between superior and subordinate
Mutual correlation, optionally, there are the subzone network topological parameter under the centralized device of relationship between superior and subordinate, to may be configured as part identical.
For example, in a kind of network topology structure of multistage network as shown in Figure 2, eNB8, eNB9 are direct with core net
The macro base station of connection is established, eNB1 to eNB7 is the small base that connection is established by one or more levels centralized device and core net
It stands, the cell under centralized device A is the administrative cell of base station eNB 1, eNB2, eNB3, and the cell under centralized device B is base
It stands eNB 6, eNB7 administrative cell, the cell under centralized device C is the administrative cell of base station eNB 4, eNB 5.Wherein, collect
Chinese style equipment B and the centralized device that centralized device A is same stages, therefore, the cell under centralized device B is set with centralization
The network topology parameters of cell under standby A are different；Centralized device B and centralized device C is centralized device not at the same level, because
This, the cell under centralized device B is different from the network topology parameters of the cell under centralized device C.Assuming that network topology is joined
Number all configures in preceding 10 bits of the cell ID of cell, then the Cell ID of the cell under eNB8, eNB9 are for storing net
The network topology parameters of cell under the small base station of any of the configuration of preceding 10 bit of network topological parameter and eNB1 to eNB7
Configuration is different.And preceding 10 bit configurations of the cell Cell ID under eNB1, eNB2, eNB3 are identical, and it is different from other cells,
And whole net is uniquely；Preceding 10 bit configurations of cell Cell ID under eNB4, eNB5 are identical, different from other cells, and whole net
Uniquely；Preceding 10 bit of cell Cell ID under eNB6, eNB7 are identical, different from other cells, and whole net is unique；eNB8、
Preceding 10 bit differences of cell Cell ID under eNB9, and whole net is unique.
In above-mentioned steps 101, the candidate adjacent of this cell refers to all peripheral cells of this cell that can be obtained.This is small
The candidate adjacent information in area includes the neighboring BS information that this cell is newly obtained directly under base station, and/or, it is the configured adjacent area of this cell
Information.
Specially：When base station newly powers on, the neighboring BS information newly obtained is determined as to the candidate adjacent information of this cell；Base
Stand operation when, by for the configured neighboring BS information of this cell, and/or, the neighboring BS information newly obtained is determined as the candidate of this cell
Neighboring BS information.Therefore, above method flow of the invention is by time restriction, when can be applied to base station initial power-on from
Configuration process can be used for the self-optimizing process of base station after the power is turned on, applied widely.
Wherein, the neighboring BS information newly obtained includes but not limited to：The neighboring BS information listened to, centralized device where base station
The neighboring BS information issued, the neighboring BS information that cell type is changed in configured adjacent area, it is adjacent area unidirectionally to configure this cell
Cell information, the base station configuration being more suitable in multistage network topological structure optimize neighboring cell list.For example, if base station is detectd
It listens, the adjacent area newly obtained includes the cell listened to；If base station is established with centralized device (such as webmaster) and is connected, if centralization is set
Standby to issue adjacent area, the adjacent area newly obtained includes the adjacent area that centralized device issues；If base station is built with centralized device (such as webmaster)
Vertical connection, the adjacent area newly obtained include to be configured with the cell that this cell is adjacent area by what centralized device obtained；If UE is measured
Discovery is reported to be not configured as the cell of adjacent area, the adjacent area newly obtained includes the cell for being not configured as adjacent area；What if base station received
Cell of the signaling in non-configured neighboring cell list, the adjacent area newly obtained include the cell.
In step 102, base station carried out when neighboring cell list configuration or optimization the setting of the cell type of candidate adjacent, subtracts
Lack the interaction with management station equipment, it is more efficient, it realizes simpler.Base station can be set according to the network topology parameters of candidate adjacent
Set cell type, as the foundation of candidate adjacent priority ranking, preferably in topology with more small of this cell switching demand
Area, energy Adapted for Network topology meet practical gravity treatment/switching demand of network, and can optimize adjacent area according to the change of network topology
List.The cell type of candidate adjacent is arranged according to the network topology parameters of candidate adjacent for any candidate adjacent, including：
Judge whether the network topology parameters of candidate adjacent meet the network topology parameters configuration of macro base station cell, if so, by candidate
The cell type of adjacent area is set as the first kind；
If it is not, judge whether the network topology parameters of candidate adjacent are identical as the network topology parameters of this cell, if identical,
It then sets the cell type of candidate adjacent to Second Type, if differing, is judged according to the network parameter of candidate adjacent candidate
Adjacent area whether be the affiliated centralized device in this base station upper level centralized device under cell, if so, by the small of candidate adjacent
Area's type is set as third type, if it is not, setting the cell type of candidate adjacent to the 4th type.
Wherein, judge whether candidate adjacent is the affiliated centralized device in this base station according to the network topology parameters of candidate adjacent
Upper level centralized device under cell, a kind of mode that may be implemented is：It will be under the centralized device of relationship between superior and subordinate
Subzone network topological parameter may be configured as that part is identical so that there are the subzone networks under the centralized device of relationship between superior and subordinate
Topological parameter is interrelated, relies in this way, according to the network topology parameters of candidate adjacent, if the network topology parameters of candidate adjacent
Part field it is identical as the corresponding field of the network topology parameters of this cell, it is determined that candidate adjacent is to collect belonging to this base station
Cell under the upper level centralized device of Chinese style equipment；If the part field of the network topology parameters of candidate adjacent and this cell
Network topology parameters corresponding field it is different, it is determined that candidate adjacent is not the upper level collection of the affiliated centralized device in this base station
Cell under Chinese style equipment.
For example, the value of the cell type of candidate adjacent is defined as { 0,1,2,3 }.Candidate adjacent is macro base station cell, then
The cell type value of candidate adjacent is 0；Candidate adjacent and this cell are the cells under same centralized device, then candidate adjacent
Cell type value be 1；This cell is established by multistage centralized device and core net and is connected, and candidate adjacent is this cell
Cell under upper level centralized device, then the cell type value of candidate adjacent is 2；This cell passes through multistage centralized device
It establishes and connects with core net, and candidate adjacent and this cell be under same concentrating equipment, nor be this cell upper level
Cell under centralized device, then the cell type value of candidate adjacent is 3.
Based on the example above, flow according to the method described above, if the cell type of candidate adjacent is set as the first kind,
One type value is 0；If the cell type of candidate adjacent is set as Second Type, Second Type value is 1；If candidate adjacent
Cell type be set as third type, then third type value be 2；If the cell type of candidate adjacent is set as the 4th class
Type, then the 4th type value is 3.
In conjunction with the example above, if being carried out to the cell under eNB4 in the network topology structure of multistage network shown in Fig. 2 adjacent
Area configures, and first has to the candidate adjacent information according to acquisition, and the setting of cell type is carried out to corresponding candidate adjacent, if
The candidate adjacent information that eNB4 is obtained includes the network topology parameters of the cell under eNB3, eNB5, eNB7, eNB9.ENB5 and
ENB4 is the small base station under same centralized device, therefore the configuration phase of the network topology parameters of the cell of affiliated eNB5 and eNB4
Together；The affiliated centralized devices of eNB3 and the affiliated access devices of eNB4 are centralized devices not at the same level, therefore the cell of affiliated eNB3
Network topology parameters configuration it is different from the configuration of the network topology parameters of the cell of affiliated eNB4, and it is whole net uniquely；eNB7
Affiliated centralized device is the upper level centralized device of the affiliated access devices of eNB4, therefore, the network of the cell of affiliated eNB7
The configuration of topological parameter is different from the configuration of the network topology parameters of the cell of affiliated eNB4, and whole net is unique；ENB9 is direct
The macro base station being connect with core net, the network of the configuration and the cell of affiliated eNB4 of the network topology parameters of the cell of affiliated eNB9
The configuration of topological parameter is different, and whole net is unique.Therefore, it when cell type being set according to network topology parameters, is obtained according to eNB4
The candidate adjacent information taken, the network that the cell under eNB9 is met from the configuration for filtering out network topology parameters in candidate adjacent are opened up
The cell type of the candidate adjacent is set as 0 by the candidate adjacent for flutterring the configuration of parameter；It is filtered out from remaining candidate adjacent
The cell type of the candidate adjacent is arranged for the network topology parameters of network topology parameters and eNB4 identical candidate adjacent
It is 1, the different candidate adjacent of network topology parameters of network topology parameters and eNB4 is filtered out from remaining candidate adjacent,
And the cell type of the candidate adjacent for the configuration for configuring the network topology parameters for meeting the cell under eNB7 is set as 2, it will match
The cell type for setting the candidate adjacent of the configuration for the network topology parameters for meeting the cell under eNB3 is set as 3.
The above process is taken into account the topology of multistage network, according to the cell type of candidate adjacent preferably in topology
The more cell with this cell switching demand, energy Adapted for Network topology, and neighboring cell list can be optimized according to the change of network topology.
In above-mentioned steps 103, according to the adjacent area attribute of the cell type of candidate adjacent and candidate adjacent, candidate adjacent is set
Priority.Because the candidate adjacent in the present invention includes not only configured adjacent area, it may also include the adjacent area newly obtained, therefore can be with
Realization is configured the priority of newfound candidate adjacent.The cell type of present invention combination candidate adjacent and candidate adjacent
Adjacent area attribute setting candidate adjacent priority, and then configured according to priority and optimize neighboring cell list and can more be bonded network and opened up
The switching demand flutterred, Adapted for Network topological structure.
Specifically, according to the cell type of candidate adjacent, the priority of candidate adjacent is set, to realize according to multistage network
The switching demand configuration of topology and optimization adjacent area, it is preferred that as shown in figure 3, adjacent according to the cell type of candidate adjacent and candidate
The adjacent area attribute in area, is arranged the priority of candidate adjacent, it may include following steps：
Step 301, it is Second Type by cell type, adjacent area attribute is that the new adjacent area or adjacent area attribute of obtaining is that this is small
The priority for the candidate adjacent that the configured adjacent area in area and handover success rate are not less than the first threshold value is set as the first priority；Institute
The first threshold value is stated, according to actual setting, value range is 0~1.
Step 302, the priority for the candidate adjacent that cell type is the first kind is set to the second priority；
Step 303, it is third type by cell type, adjacent area attribute is the configured adjacent area of this cell, and handover success rate
Priority not less than the candidate adjacent of the first threshold value is set as third priority；
