Abstract
The present invention discloses a method for generating neighbor list, wherein, the terminal reports the information of at least one unknown cell which is not in present neighbor list to the base station. The base station transmits cell information obtainment request information to the network side data base. Furthermore the cell information obtainment request information carries the information of service cell comprising the cell and the information of unknown cell. The network side responds to the cell information obtainment request information, confirms the position of service district according to information of service district through the database and searches the candidate cell according to the confirmed position of service cell for further confirming the selected cell. The network side transmits the cell information obtainment request information to the base station, wherein the cell information obtainment request information carries the information of selected cell. The information of selected cell comprises the global identifier of selected cell. The base station executes neighbor list procession according to the cell information obtainment request information. The invention also discloses a method for obtaining neighbor information. The automatic generation of neighbor list can be realized through the invention.
Description
technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for obtaining neighbor cell information and a method for generating a neighbor cell list in a Long Term Evolution (LTE for short) system. Background technique [0002] 36300-800 describes that the Long Term Evolution (LTE) network consists of E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network), base station eNB (Evolved NodeB) and evolved packet switching center ( Evolved Packet Core, referred to as EPC), the network structure is flat. figure 1 is a schematic diagram of the LTE network structure, such as figure 1 As shown, the EUTRAN includes a set of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2, wherein S1 and X2 are logical interfaces. One EPC can manage one or more eNBs, one NodeB can also be controlled by multiple EPCs, and one eNB can manage ...
