Problems solved by technology

[0004] During the handover pre-registration process and the actual execution process of the handover in the active mode, the adjacent cell information stored on the evolved base station (evolved-NodeB, e-NodeB) (eNB for short) is used to complete the high-speed packet data access network (High Rate Packet Data Access Network, HRPD AN) selection and tunnel establishment, but the information of the adjacent cell is statically configured on the eNB, which causes that when the information of the adjacent cell in the HRPD network changes, the information of the adjacent cell on the eNB Due to the static configuration, it is not consistent with the latest actual adjacent cell information in the HRPD network. If the UE performs handover from the LTE network to the HRPD network at this time, the adjacent cell information in the HRPD network used in the process is different from the actual Adjacent cell information in the HRPD network does not match, which may lead to handover failure

Abstract

The invention discloses method, device and system for maintaining adjacent district information among heterogeneous networks, wherein the method comprises the following steps of: receiving an updating message of the adjacent district information from an entity of a target network side; and updating the adjacent district information on an access network entity of a source network side according to the updating message of the adjacent district information. The invention is used for dynamically updating the adjacent district information to ensure the information synchronization among the heterogeneous networks and avoid terminals being unsuccessfully switched among the heterogeneous networks, and then the satisfactions of users are enhanced.

Description

technical field [0001] The present invention relates to the field of communication networks, in particular to a method for maintaining adjacent cell information between heterogeneous networks, a target network side device, a source network side access network device, a source network side mobility management device, and a method for maintaining adjacent cell information between heterogeneous networks system. Background technique [0002] After the network evolves, the terminal can obtain required business services through one of different evolved network structures. Moreover, it is possible to switch between different network structures arbitrarily, but the continuity of the business needs to be guaranteed. For handover between different evolved network structures, the following requirements must be met: the least impact on the handover network; the least impact on user equipment (User Equipment, UE); the least coupling between the handover networks; the service can be guar...
