Abstract

The embodiment of the invention discloses a load information interaction method comprising the following steps of: sending the load information of a cell managed by an access network node and the identifications of target cells positioned in other systems to a top management node by the access network node of a first system; and receiving the information returned by the top management node, wherein the information carries the load information of the target cells. The embodiment of the invention simultaneously provides a device and a system for realizing the method. The embodiment of the invention provides a specific scheme for interacting the load information of the cells among different systems so that each system fully knows the load situations of the cells in other systems, and therefore, a network side can comprehensively take the load situations of a service cell of the current UE (User Equipment) and other cells after receiving the measuring report of user equipment (UE) in an activated state to select the cell with lower load as the target cell for the UE and switch the cells, thereby improving load balancing situations and improving the integral performance of the system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a load information interaction method, device and system. Background technique [0002] Long-Term Evolution (LTE) / System Architecture Evolution (SAE) plans new interfaces between the radio access network and the core network and internal interfaces of the radio access network for the evolved system: S1 interface and X2 interface. In the LTE system, base stations (eNBs) exchange cell load information through the X2 interface to achieve load balancing within the system. [0003] However, for load balancing among different systems, such as LTE system, UMTS radio access network (UTRAN) system and GSM / EDGE radio access network (GERAN) system, there is no specific implementation method in the prior art so far. Contents of the invention [0004] In view of this, the present invention provides a load information interaction method, device and system to re...
