Neighborhood information management method and system

Abstract

The present disclosure discloses a method and a system for managing neighboring cell information. The method includes: a radio network controller sends a notification message to user equipment (UE), wherein the notification message includes an indication which notifies the UE to measure inter-frequency cells which are not in an inter-frequency neighboring cell list or inter-system cells which are not in an inter-system neighboring cell list; after receiving the notification message, the UE measures the inter-frequency cells, which are not in the inter-frequency neighboring cell list, indicated in the notification message, or measures the inter-system cells, which are not in the inter-system neighboring cell list, indicated in the notification message, and reports the measurement result. In the present disclosure, the UE reports a measurement result to the network side after measuring the cells which are not in the neighboring cell list, to improve the capability of the network side to obtain neighboring cell information. Based on the measurement result reported by the UE, the network side decides inter-frequency handover or inter-system handover, so that the UE performs handover in time and the call drop is prevented effectually.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, relates to a neighboring cell information management method and system. Background technique [0002] It is a basic function of the cellular mobile communication system to ensure the service continuity of mobile users, and the handover of the service cell of the mobile station is the main means to ensure the service continuity. In order to facilitate user equipment (User Equipment, referred to as UE) handover, the system needs to configure the adjacency relationship for each cell, so that the network side notifies the adjacent cell information to the user equipment, and the user equipment reports the measurement results after measuring the adjacent cells. Instruct the user equipment to handover a certain neighboring cell. [0003] Which neighboring cells exist around a certain cell is not only related to the distance of the cell, but also closely related to the wi...

Problems solved by technology

However, the problem of missing allocation of inter-frequency adjacent cells and inter-system adjacent cells cannot be solved, especially in the three systems of Time Division-Synchronous Code Division Multiple Access (TD-Synchronous Code Division Multiple Access, referred to as TD- When SCDMA), Code Division Multiple Access (CDMA2000 for short), and Wideband Code Division Multiple Access (WCDMA for short) all coexist, the problem of missing allocation of adjacent cells is particularly serious. There is no solution to the problem of missing adjacent cells between regions and systems
