Description
Technical field
The present invention relates to DR alarm distribution technology, relate in particular to a kind of cell power method of adjustment based on Automatic Neighboring Relation and device, base station.
Background technology
Seismic sea wave warning system (ETWS, Earthquake and Tsunami Warning System) can need the mobile phone users of evacuating to send alarm notification for facing the disasters such as seismic sea wave, the mobile phone users that receives alarm notification can know that danger arriving or occurring, when user can determine and to where evacuating etc. according to alarm notification, ETWS helps people and averts a calamity or reduce the loss that disaster is brought, alarm information is generally by mobile management net element (MME, Mobility Management Entity) notice is to base station (eNB, eNB), by eNB, be handed down to mobile phone users again.
ENB will safeguard neighborhood region correlation chart (NRT for little district under self sets up, Neighbor Relation Table), and obtain Automatic Neighboring Relation (ANR, Automatic Neighbour Relation), its target is exactly automatically to set up and safeguard neighborhood region correlation chart, by down-run survey configuration order, configuration information is sent to subscriber equipment (UE, User Equipment), and at the adjacent area of eNB detection module, receive the measurement report of UE, find new adjacent area and obtain the necessary information of adjacent area.
The cell power adjustment of eNB, generally all controls platform configuration by operational administrative and completes, and this configuration is the configuration of manual type, and after having configured, is changeless substantially.Meanwhile, the consideration that optimization Network Based and minimizing are disturbed adjacent area, the actual emission power of the general cell configuration maximum transmission power that community, community is supported far away.
When the natural calamities such as earthquake or tsunami are come interim, although some eNB have received ETWS alarm information, but may be impaired and cannot work in some base station in earthquake or tsunami, the scope that these impaired base stations cover cannot access user, and int base station may be less due to cell power configuration, and fail dynamically to adjust the actual emission power of community, cause not impaired base station cell to fail to cover the coverage of impaired base station, cause the user of impaired base station range can not receive in time alarm information, have no way of knowing that emergence message is as escape information etc.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of cell power method of adjustment based on Automatic Neighboring Relation and device, base station, can be when the natural calamities such as earthquake, tsunami or fire be arrived or occur, in time notice UE user escapes and saves oneself etc., can notify UE user as much as possible with the covering of maximum magnitude.
For achieving the above object, technical scheme of the present invention is achieved in that
A cell power method of adjustment for Automatic Neighboring Relation, is characterized in that, described method comprises:
Base station side is carried out Automatic Neighboring Relation detection after receiving urgent alert messages, while failing effective neighboring BS information to be detected, adjusts the transmitting power of self.
