specific Embodiment

[0095] like Image 6 As shown, it is another specific embodiment of the method for updating neighbor cell information in the embodiment of the present invention, the method includes:

[0096] 601. Before cell handover occurs, acquire the PHY_ID of the cell reported by the UE and acquired during the UE measurement process.

[0097] 602. Determine whether the locally stored NRT contains the PHY_ID, and if not, perform 603; if it does, modify the performance parameters of the cell.

[0098] 603. Determine whether there is a GCI corresponding to the PHY_ID in the locally saved Temp NRT, if yes, go to 604, if not, go to 605.

[0099] 604. Modify the performance parameters of the cell corresponding to the GCI, and judge whether the corresponding cell is an adjacent cell by the eNB or the OSS, and set three attribute values ​​(namely NOremove attribute, NO HO attribute) in the adjacent cell information according to the judgment result and NO X2 attributes), if the cell is an adjace...

Abstract

The invention discloses a method, a device and an evolution base station for updating information in adjacent regions. The method comprises the following steps of acquiring UE historical information of user equipment (UE) which comprises a global logo and a local logo of a subdistrict; and updating information in adjacent regions according to the UE historical information. In the embodiment of theinvention, due to carrying the global logo and the local logo of the subdistrict by the UE historical information, the base station can update information in adjacent regions according to the above two logos so as to acquire information in adjacent regions which are possible to be in missed matching and improve the capability of automatically optimizing adjacent regions in the network.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and base station for updating neighboring cell information. Background technique [0002] In a Long Term Evolution (LTE) self-organizing network (Self Organization Network, SON), an automatic neighbor relation (Automatic Neighbor Relation, ANR) function is used to implement automatic neighbor relation establishment and maintenance. An important aspect of the ANR function is to reduce the missing configuration of adjacent cells as much as possible to improve the success rate of handover. What needs to be solved for the missing configuration of adjacent cells is how to effectively obtain the physical identity (PHY_ID) of the new cell and its corresponding global cell ID (Global cellID, CGI or GCI) and determine the relationship between adjacent cells stably and effectively. Different cells have unique GCIs. Cells under the same eNB have different PHY_ID...
