Optimization of interlayer handovers in multilayer wireless communication networks

An apparatus for parameter optimization of at least one interlayer handover in a multilayer wireless cellular communication network comprising a processor and a memory, said memory containing instructions executable by said processor, whereby said apparatus is operative to:

• obtain information indicative of load in the communication network;
• average the obtained information for the communication network over a period of time;
• determine based on the averaged information whether optimization of the communication network is required;
• and
• in response to determining that optimization of the communication network is required, optimize the interlayer handover parameters by generating a new set of configuration parameters for the interlayer handover based on the obtained information indicative of load in the communication network and a current set of configuration parameters, and apply the new set of configuration parameters to the communication network,
• wherein the interlayer handover parameters define criteria for interlayer handover between a first frequency layer of a macrocell and a second frequency layer of a microcell, and
• wherein at least one of the optimized interlayer handover parameters is a speed related threshold parameter.

A non-transitory computer-readable storage medium having computer-readable instructions stored thereupon which, when executed by a processor, will cause the processor to:

• obtain information indicative of load in a multilayer wireless cellular communication network;
• average the obtained information for the communication network over a period of time;
• determine, based at least in part on the averaged information, whether optimization of the communication network is required;
• and
• in response to determining that optimization of the communication network is required, optimize an interlayer handover parameters in the communication network by generating a new set of configuration parameters for the interlayer handover based on the obtained information indicative of load in the communications network and a current set of configuration parameters, and applying the new set of configuration parameters to the communication network,
• wherein the interlayer handover parameters define criteria for interlayer handover between a first frequency layer of a macrocell and a second frequency layer of a microcell, and
• wherein at least one of the optimized interlayer handover parameters is a speed related threshold parameter.
