Embodiment Construction

[0034] Embodiments of the present invention provide a load measurement method, device and system. In order to better describe the above method, device and system, the load balancing technology in the LTE system is now introduced.

[0035] There are three types of cell loads involved in load balancing, namely HW (Hardware load, hardware load), TNL (Transport Network Layer, transport layer load) and air interface load. Wherein, HW is the load measurement at the eNB level, which measures the hardware working status of the eNB. The air interface load is measured by the PRB usage rate of the physical resource block.

[0036] When a cell finds that its air interface is heavily loaded, and the HW and TNL are not overloaded, the eNB where the cell is located acts as a load balancing initiating base station, triggers the air interface load balancing process, and initiates load measurement to the adjacent cell evolution base station. The eNB first sends a measurement request message to...

Abstract

The embodiment of the invention discloses a load measuring method, an evolution base station and a load measuring system, which relate to the field of communication and solve the problem of complex signaling interaction process in the load balancing process. The load measuring method comprises the following steps: receiving a measurement request message which is sent by an adjacent area evolution base station and comprises more than two sets of load measurement parameters; performing measurement configuration according to the more than two sets of the load measurement parameters so as to determine the load measurement state; and sending a response message to the adjacent area evolution base station, wherein the response message carries the load measurement state. The technical proposal provided by the embodiment of the invention is applicable to cell load balancing of LTE systems and LTE advanced systems.

Description

technical field [0001] The present invention relates to the communication field, in particular to a load measurement method, an evolved base station and a load measurement system. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) project is the evolution of the third-generation mobile communication technology 3G. It improves and enhances the 3G air access technology, and has the advantages of packet transmission, delay reduction, wide-area coverage and backward compatibility. [0003] In order to reduce the cost of network construction and operation and maintenance, NGMN (Next Generation Mobility Network, next-generation mobile network) puts forward S ON (Self Organization / Optimization Network, self-organization / optimization network) requirements for LTE. Mobility Load Balancing is a self-optimizing feature of SON. In a mobile network, the randomness of UE (User Equipment, user equipment) location and the diversity of service requirements will...
