Elevator call allocation and transmission based on a determination of walker speed

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:

• determining a first position of a user of a mobile node at a first time instant, the first position being determined based on a proximity of a proximity card of the user to a first proximity card reader having a predetermined position;
• determining a second position of the user of the mobile node at a second time instant following the first time instant, wherein the determining of the second position of the user of the mobile node is performed in response to a condition, the condition being at least one of a determination that a predefined time has elapsed from the first time instant, a determination using at least one inertial position measurement that the user has walked a predefined distance from the first position, a determination using at least one positioning that the user has entered a predefined area in a floor, and a determination that the user has made an elevator call after the first time instant;
• determining a time difference between the first time instant and the second time instant;
• determining a walking speed of the user using the time difference, the first position and the second position;
• determining a third position of the user of the mobile node;
• determining a walking time required for the user to reach at least one elevator from the third position based on the walking speed of the user;
• and
• transmitting the elevator call and the walking time to an elevator call control node.

A computer program embodied on a non-transitory computer readable medium comprising code adapted to cause the following when executed on a data-processing system:

• determining a first position of a user of a mobile node at a first time instant, the first position being determined based on a proximity of a proximity card of the user to a first proximity card reader having a predetermined position;
• determining a second position of the user of the mobile node at a second time instant following the first time instant, wherein the determining of the second position of the user of the mobile node is performed in response to a condition, the condition being at least one of a determination that a predefined time has elapsed from the first time instant, a determination using at least one inertial position measurement that the user has walked a predefined distance from the first position, a determination using at least one positioning that the user has entered a predefined area in a floor, and a determination that the user has made an elevator call after the first time instant;
• determining a time difference between the first time instant and the second time instant;
• determining a walking speed of the user using the time difference, the first position and the second position;
• determining a third position of the user of the mobile node;
• determining a walking time required for the user to reach at least one elevator from the third position based on the walking speed of the user;
• and
• transmitting the elevator call and the walking time to an elevator call control node.
