Embodiment 1

[0061] In this embodiment, the process of negotiating cell reselection parameters between the source base station and the target base station is proposed based on an independent X2 interface message, specifically as figure 2 shown, including the following steps:

[0062] Step 201: When the source base station has modified the cell reselection parameters of the cell under it, the source base station sends a cell reselection parameter modification request message to the target base station, and the cell reselection parameter modification request message includes message type, cell identification information (source cell ID and / or target cell ID) and the cell reselection parameter modification information of the source cell;

[0063] In this step, the cell reselection parameter modification information of the source cell includes one or more of the following information:

[0064] The current cell reselection parameters of the source cell (that is, the cell reselection parameter...

Embodiment 2

[0086] In this embodiment, the process of negotiating cell reselection parameters between the source base station and the target base station reuses the messages of the mobility parameter negotiation process, specifically as image 3 shown, including the following steps:

[0087] Step 301: When the source base station modifies the cell reselection parameters of the cell under it, the source base station sends a mobility parameter modification request message to the target base station, and adds the cell reselection parameter modification information of the source cell to the mobility parameter modification request message ;

[0088] In this step, the cell reselection parameter modification information of the source cell includes one or more of the following information:

[0089] The current cell reselection parameters of the source cell (that is, the cell reselection parameters before the source cell is modified), the source cell reselection parameter modification amount, and...

Embodiment 3

[0106] In this embodiment, the process of negotiating cell reselection parameters between the source base station and the target base station is implemented through S1 interface messages, specifically as Figure 4 shown, including the following steps:

[0107] Step 401: When the source base station modifies the cell reselection parameters of the cell under it, the source base station sends a cell reselection parameter modification request message to the MME through the S1 interface, and the cell reselection parameter modification request message includes message type, cell identification information ( source cell ID and / or target cell ID) and the cell reselection parameter modification information of the X cell;

[0108] In this step, the cell reselection parameter modification information of the source cell includes one or more of the following information:

[0109] The current cell reselection parameters of the source cell (that is, the cell reselection parameters before th...

Abstract

The invention discloses a method and a base station for implementing cell reselection parameter negotiation and relates to the technical field of wireless communication. The method comprises the following steps that: when a cell reselection parameter in a first cell under a first base station is modified, the first base station transmits cell reselection parameter modification information of the first cell to a second base station which is adjacent to the first cell and to which the second cell belongs; and the second base station receives the cell reselection parameter modification information of the first cell, and feeds a response back to the first base station, wherein the response is used for showing a cell reselection parameter modification result. The technical scheme solves the problem that the modified cell reselection parameter in any cell of neighbor cells causes unnecessary cell reselection or switching.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and a base station for realizing cell reselection parameter negotiation. Background technique [0002] The Long Term Evolution (LTE) network of the third-generation mobile communication consists of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and the Evolved Packet Core (EPC) network. composition. E-UTRAN includes a collection of evolved base stations (Evolved NodeB, eNB), EPC includes Mobile Management Entity (Mobile Management Entity, MME) and Serving Gateway (Serving Gateway, S-GW), etc., and the network architecture is flat. Wherein, the eNB and the MME are connected through the S1 interface, the eNB and the S-GW are connected through the S1 interface, and the eNBs can be connected through the X2 interface. S1 and X2 are logical interfaces. One MME or S-GW can manage one or more eNBs, and one eNB can also be controlled by multipl...
