Optimization method for base station switching

Abstract

The utility model discloses an optimization method for the switchover of the base station, comprising that when the switchover sent to a target district by a terminal is refused, the failure information of the switchover can be stored in the terminal historical information of the request message of the switchover by a base station of the present district of the terminal, wherein, the failure information of the switchover comprises the relevant information of the target district refusing the switchover of the terminal; in the situation that the terminal is switched to another target district successfully, the failure information of the switchover is sent to the base station of another target district by the base station of the present district; if the terminal continues switching, the base station of other target district chooses the target district for successive switching based on the failure message. The utility model can choose the most suitable target district for the terminal, realize the optimization of the switching process and increase the success rate of the switchover.

Description

technical field [0001] The present invention relates to the field of wireless cellular communication, and in particular, relates to an optimization method for switching base stations in an LTE mobile communication system. Background technique [0002] The LTE network described in 36300-800 of the 3GPP LTE (Long Term Evolution) standard series consists of an E-UTRAN (Evolved UTRAN) base station eNB (Evolved NodeB) and an evolved packet switching center (Evolved PacketCore, EPC). The network is flat change. The EUTRAN includes a set of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2. 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 one or more cells. [0003] The handover of the LTE is divided into a handover process of the S1 interface and a handover process of the X2 interface. In the current R8 protocol 36.423, the handover pro...

Problems solved by technology

[0004] However, when handover is performed, in the current system, if a terminal fails to handover due to certain resource constraints, and the resource cannot be recovered within a period of time, the cell where the resource is located is not suitable for the terminal to handover during this period of time. target, and, within this period of time, if a cell that is not suitable as the handover target of the terminal is requested by the terminal again, there will be a high handover failure rate

[0005] Therefore, it is necessary to have a technical solution that can solve the above-mentioned problem of low success rate of base station handover
