[0029] This embodiment mainly describes the flow of the method for the base station to close the cell to realize self-optimization, that is, describes the switching of the state of the cell from the open state to the closed state. see figure 2 , figure 2 The flow chart of the first embodiment provided by the present invention. Such as figure 2 As shown, the process may specifically include the following steps:

[0030] Step 201, eNB1 judges whether the current load of the open cell controlled by it is lower than the set threshold value, and eNB1 determines that the cell needs to be shut down based on the load of the current cell and the load of the adjacent cells to the current cell, and executes step 202 ; Otherwise, maintain the open state of the cell. The eNB1 knows the load conditions of the adjacent cells of the adjacent eNB according to the resource status update process of the existing X2 interface (for details, please refer to the 3GPP specification TS36.423). ...

[0145] see Figure 9 , Figure 9 The flow chart of the second embodiment provided by the present invention. This embodiment is described by taking the switching from the closed state of the cell to the open state as an example, as Figure 9 As shown, the process may include the following steps:

[0146] In step 901, the eNB1 judges whether it needs to open the closed cell under its control, and if so, executes step 902; otherwise, ends the process.

[0147] Here, when the judgment in step 901 is specifically implemented, there may be multiple implementation forms, such as:

[0148] The first way: eNB1 judges whether the load of the cell has exceeded the preset threshold for each cell currently controlled by eNB1, and if so, determines that the cell is overloaded. In order to ensure the quality of service provided by the cell, eNB1 The closed cell controlled by itself that has a coverage relationship with the cell is opened, and a part of the load is shared by the closed ce...

Abstract

The invention discloses a method for realizing self optimization in a mobile communication system, a system and a base stations, wherein the method comprises the following steps that: (A) a first base station judges whether the current state of a cell controlled by the first base station needs to be switched into another state which is opposite to the current state or not, if yes, a cell state notification is sent to all base stations being adjacent to the first base station; the cell state notification carries a mark of the cell the state of which needs to be switched; and (B) the base stations which are adjacent to the first base station update the state corresponding to the cell mark carried by the cell state notification in a proximity relation list. By adopting the invention, the self optimization in the mobile communication system can be realized.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method, system and base station for realizing self-optimization in a mobile communication system. Background technique [0002] In mobile communication technology, in order to simplify the signaling process and shorten the information transmission delay, the Evolved UMTS Radio Access Network (EUTRAN: Evolved UTRAN) abandoned the Radio Network Control (RNC) and Node B (NodeB) structure of UTRAN, It is completely composed of a base station (eNB: eNodeB). see figure 1 , figure 1 It is a simple topology structure of the EUTRAN network in the prior art. Such as figure 1 As shown, EUTRAN mainly includes eNB, and preferably, may further include home base station (HeNB). Among them, the EUTRAN network can be connected to the core network through the S1 interface, specifically: eNBs or HeNBs in the EUTRAN network are connected to entities in the core network such as mobile managem...
