Embodiment Construction

[0029] In the present invention: first, according to factors such as network planning, cell location, and special needs, pre-configure the neighbor relationship table within the eNB and between eNBs on the eNB, but before the cell is established, the relevant neighbor relationship table is invalid, The system information and radio network resource (RRC) connection reconfiguration message sent by the relevant neighboring cell does not include the relevant neighboring cell relationship entry. After the eNB starts up and the cell is established, in order to satisfy the cell reselection and handover before the eNB screening, the eNB and the adjacent eNB set the neighbor relation table item related to the cell as pre-validation, and send the system information message, the system The information change message and the RRC connection reconfiguration message include the neighbor cell relationship table, and notify the UE to start periodic measurement of the cell. The eNB will subsequ...

Abstract

The invention discloses a network self-organization method and an evolution base station eNB. The method comprises the following steps that: when the eNB is started, the state of a neighborhood relation table in the eNB is set to be pre-valid; the eNB sets up a request message through X2 to send the neighborhood relation table thereof to a neighboring eNB and receive the neighborhood relation table of the neighboring eNB, which is returned by the neighboring eNB; the eNB sets the state of the neighborhood relation table between the eNB and the neighboring eNB to be pre-valid according to the neighborhood relation table of the neighboring eNB; and the eNB evaluates the neighborhood relation represented by the neighborhood relation table in the pre-valid state and changes the pre-valid state of the neighborhood relation table to be valid or invalid according to the evaluation result. The technical scheme of the invention optimizes neighboring configuration, so that switch judgment can use precise neighboring information and a switch success rate of a network is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a network self-optimization method and an evolved base station eNB. Background technique [0002] A Long Term Evolution (LTE, Long Term Evolution) network is a flat network. figure 1 It is a schematic diagram of an existing LTE network structure. Such as figure 1 As shown, the LTE network is composed of the Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) and the Evolved Packet Switching Center (EPC, Evolved Packet Core). A radio network controller (RNC, Radio Network Controller) is installed to reduce network delay. EPC includes Mobility Management Entity (MME) and Service Gateway (S-GW). The E-UTRAN includes a collection of evolved base stations (eNBs) connected to the EPC through the S1 interface, and the eNBs are connected through the X2 interface, and each ENB includes multiple cells. [0003] At present, since 2G, 3G and LTE will coexist for...
