Description

Implementation method and the device of a kind of minizone load balance
Technical field
The present invention relates to Long Term Evolution (LTE, Long Term Evolution) technology, particularly implementation method and the device of load balance between a kind of LTE system small area.
Background technology
The LTE system is resource limited system, the resource of each residential quarter is limited, increase along with number of users and professional number, the load of residential quarter can increase gradually, and the increase of cell load can affect the index performance of customer service, if can not reduce timely and effectively the load of residential quarter, when the load of system is increased to the warning line of system, the rapid variation of performance that can cause system, even can cause system crash, main manifestations is: the access success rate is low, handover success rate is low, descending power load is too high and neighboring interval disturbs large etc.Therefore, for so that the load of each residential quarter in certain zone all in a horizontal line, thereby so that system is more stable and efficiently, need to carry out balance to the minizone load.
At present, in the LTE system, realize that the method for minizone load balance mainly comprises: load balancing (LB, Load Balancing) technology and mobility load balance (MLB, Mobility Load balancing) technology.Wherein, the task of LB technology is process many inter-cell traffic unbalanced, particularly, by adopting the mode of switching or re-selecting cell, the business that realizes is flowing to the underload residential quarter from the high load capacity residential quarter, thereby make Radio Resource keep higher utilance, keep to a certain extent higher service quality, and effectively reduce the probability of cutting off rate; The MLB technology is as self-organizing network (SON, Self-Organized Network) self-optimization function in, mainly be by the Automatic Optimal mobility parameters, that is: cell reselection parameters or handoff parameter, the partial service of the higher residential quarter of load is transferred to the lower adjacent area of load, thereby realize the uniform distribution of minizone load, and then improve power system capacity, and reduce artificial interference to network management.
No matter be LB technology or MLB technology, all will adjudicate as initial conditions with the current information on load in adjacent area that the current information on load in the adjacent area of LTE system is carried in the X2 mouth message and transmits; Wherein, described current information on load comprises: current wireless resource utility efficiency, current hardware information on load, current transmission load indication information, integration capability information that up-downgoing can be used and the up-downgoing ability rating indication information of residential quarter.Wherein, described current wireless resource utility efficiency comprises: Physical Resource Block (the GBR PRB of up-downgoing guaranteed rate business, Guaranteed Bit Rate Physical Resource Block) total Physical Resource Block (PRB, the Physical Resource Block) utilance of Physical Resource Block (non-GBR PRB) utilance of utilance, the non-guaranteed rate business of up-downgoing and up-downgoing; Described current hardware information on load comprises: up-downgoing hardware information on load; Described current transmission load indication information comprises: up-downgoing transmission information on load.The LB technology is output as the subscriber equipment (UE that needs switching, UserEquipment) and candidate handover cell, the MLB technology is output as amended handoff parameter or reselecting parameters, that is to say, in the LB technology, evolved base station (eNB, evolved Node B) issues the order that switches to corresponding candidate handover cell to UE, in the MLB technology, eNB issues amended handoff parameter or reselecting parameters to UE.
For the LB technology, because after UE receives orders, directly switch, so the LB technology can realize load balance rapidly, but, when switching, because UE can not be known the signal quality of corresponding candidate handover cell, therefore, the LB technology realizes switches to blind switching, and the success rate of switching can not be guaranteed; For the MLB technology, because what eNB issued to UE is amended handoff parameter or reselecting parameters, at this moment, UE switches based on measurement, in this case, UE can be known the signal quality of candidate handover cell, so the success rate of switching can be guaranteed, but, because UE need to switch based on measurement, therefore, the MLB technology realizes that the effect of load balance is slow.
