Description
Technical field
The present invention relates to mobile communication technology field more particularly to a kind of method and devices of adjacent area Automatic Optimal.
Background technique
In mobile communication system, it is transferred to another cell from a cell in calling procedure when mobile station, or
When wireless transmission, service load quantity adjustment, activation Operation and Maintenance, equipment fault etc. occur, in order to interrupt communication not, communicate
Network control system will start handoff procedure, guarantee the business transmission of mobile station.In TD-LTE network, user is only switched into
In the matched adjacent zone of current service cell, so correct neighboring BS relationship, it is ensured that the mobile phone on cell serves boundary can
It switches in time, obtains handoff gain, interference in net is reduced, to promote network service quality, it is ensured that network performance is stablized.
However, in the network of operation a period of time, due to the influence of the factors such as ground substance environment, network variation, often
The case where neighboring cell list for many cells occur no longer is allocation optimum.Thus it may cause handover failure and call drop (going offline) etc.
Service fail influences user's perception.
Current main neighbor cell optimizing method be based on minizone away from optimization method, main thought is as follows:
Adjacent section planning distance: centered on our station, the range for being A km apart from our station distance, the base station within the scope of this is participated in
Calculate minizone away from.
Based on minizone away from neighbor cell optimizing method in each parameter it is as shown in table 1, referring specifically to following table:
Wherein, the limitation of adjacent area number described in table 1 is the number limitation of the candidate adjacent cell of main plot.
Table 1 based on minizone away from neighbor cell optimizing method involved in parameter list
Seen from table 1, to an outdoor main plot, taking apart from base station absolute distance where it is the outdoor within the scope of A km
All cells under indoor base station within the scope of base station and B km are its candidate adjacent.To an indoor main plot, take apart from it
Place base station absolute distance is that all cells under all base stations within the scope of B km are its candidate adjacent.
Its absolute distance with the main plot calculated to these candidate adjacents, first indoor candidate adjacent by distance from it is small to
Big sequence, Ni candidate adjacent records actual interior adjacent area number Mi (being likely less than Ni) as interior adjacent area before taking, then
Outdoor candidate adjacent, according to being ranked up from small to large, takes S its outdoor adjacent area of conduct before outdoor candidate adjacent, institute by its distance
It states outdoor candidate adjacent number=N- and forces symmetrical adjacent area number-pressure co-sited adjacent area number-Mi.Wherein, it forces symmetrical adjacent
Area's number is influenced by symmetrical neighboring BS relationship option is forced.Co-sited adjacent area number is forced to be influenced by pressure co-sited adjacent area option.It forces
Symmetrical adjacent area forces co-sited adjacent area and interior adjacent area number Mi to might have overlapping, needs to pick weight when calculating outdoor candidate adjacent,
Outdoor candidate adjacent=N- forces symmetrical adjacent area number-pressure co-sited adjacent area number-Mi.
The existing method that (or optimization) neighboring BS relationship is planned according to geographical location (minizone distance), the influence of consideration because
Element is excessively single, only considered minizone distance, does not account for switching times between cell, performance of handoffs, covering area overlapping
Property etc. factors influence, therefore Automatic Optimal come out neighboring BS relationship there are many unreasonable, it is also necessary to more artificial participation
Correction, low efficiency.
