Technique for cable interface-based load balancing between cells

摘要

A technique for cable interface-based load balancing between first and second cells is described. Each cell comprises cable and air interfaces defining a parameter set comprising load statuses of the cable and air interfaces. A method aspect being performed in a control entity comprises the steps of determining, in the first cell, the parameter set of the first cell, obtaining the parameter set of the second cell, determining whether the load statues of the cable and air interfaces of the first cell are low, whether the air interface load status of the second cell is low, and whether the cable interface load status of the second cell is high, and reconfiguring, if a result of the determination is affirmative, at least one air interface configuration parameter of the first cell so as to off-load at least a part of mobile-originated traffic from the second cell to the first cell.

1. A method for cable interface-based load balancing, LB, between a first cell and a second cell in a mobile communication network, each cell comprising at least a cable interface and an air interface, and each cell being associated with a parameter set comprising a load status of the air interface and a load status of the cable interface of the respective cell, the method being performed in a control entity of the first cell and comprising the steps of:
determining the parameter set of the first cell; obtaining the parameter set of the second cell or information indicative thereof; determining whether the air interface load status and cable interface load status of the first cell are low, whether the air interface load status of the second cell is low, and whether the cable interface load status of the second cell is high, wherein:
the determining step is performed based on comparing the air interface load status and cable interface load status of the first cell and the air interface load status and cable interface load status of the second cell with at least one threshold each,the at least one threshold comprises a first threshold for the cable interface load status of the first cell, a second threshold for the air interface load status of the first cell, a third threshold for the cable interface load status of the second cell, and a fourth threshold for the air interface load status of the second cell, andthe third threshold is greater than the maximum of the first, second and fourth thresholds; and reconfiguring, if the determination is affirmative, at least one air interface configuration parameter of the first cell to off-load at least a part of mobile-originated traffic from the second cell to the first cell.
