BACKGROUND

The present disclosure relates generally to access control systems, and more particularly, to a system and a method of capturing user intent when interacting with multiple access controls.

An access control system is typically operated by encoding data on a physical key card that indicates access rights. Some access control systems are online where the reader can use some means to communicate with the access control system. In online systems the access rights are usually a reference identifier. Other access control systems are offline and the access rights are encoded as data that can be decoded and interpreted by the offline lock to retrieve the access rights. An example is a hotel locking system where a front desk encodes a guest card and an offline, battery powered lock on a guest room door has the means to decode the key card and permit or deny access based on the encoded access rights. Some methods of encoding access rights include sequencing where subsequent access rights have a sequence number that is greater than the prior access rights.

Various mobile devices have been utilized to open locks via an infrared ‘beam’ to the lock, which provides directionality, or a ‘push the button’ on the box to wake up the lock for subsequent communication over Bluetooth. With the capability present in Bluetooth Low Energy (BTLE) to communicate with very low power, new system architectures require the lock to be ‘always on’ and sending periodic BTLE advertisements, such as once per second. The very low power requirements result in many years of battery life. With this setup, a user would not need to ‘push a button’ to wake the lock up—it is already awake, however, in environments where there are multiple locks within range of the mobile device such as in a Hotel, each user may receive the advertisement from a significant number of locks thereby complicating the capture of user intent.

SUMMARY

A method of advertisement filtering according to one disclosed non-limiting embodiment of the present disclosure can include receiving advertisements from each of a multiple of access controls on a mobile device; filtering the received advertisements based on a credential on the mobile device; comparing the filtered received advertisements; and determining a user intent to access a particular access control in response to the comparing and to a communication.

A further embodiment of the present disclosure may include wherein the access control is a lock.

A further embodiment of the present disclosure may include wherein the mobile device is a smartphone.

A further embodiment of the present disclosure may include sorting the filtered received advertisements based on a RSSI (received signal strength indicator).

A further embodiment of the present disclosure may include wherein the communication is a prior communication.

A further embodiment of the present disclosure may include wherein the communication includes a time of day.

A further embodiment of the present disclosure may include wherein the communication includes location information.

A further embodiment of the present disclosure may include wherein the prior communication includes location information and time of day.

A further embodiment of the present disclosure may include wherein the prior communication is received from another user.

A further embodiment of the present disclosure may include wherein the prior communication includes location information and time of day.

A further embodiment of the present disclosure may include wherein the communication is from a passenger conveyance.

An access control system according to one disclosed non-limiting embodiment of the present disclosure can include a multiple of access controls; and a mobile device in communication with the multiple of access controls, the mobile device operable to determine a user intent to access a particular access control of the multiple of access controls based at least in part on a communication.

A further embodiment of the present disclosure may include wherein the communication is based at least in part on at least one of a GPS module, and an accelerometer in the mobile device.

A further embodiment of the present disclosure may include wherein the communication is based at least in part on a time of day of the communication.

A further embodiment of the present disclosure may include wherein the communication is based at least in part on a location indicated by the communication.

A further embodiment of the present disclosure may include wherein the communication is based at least in part on communication between the mobile device and a passenger conveyance.

A further embodiment of the present disclosure may include wherein the passenger conveyance is an elevator.

A further embodiment of the present disclosure may include wherein the communication includes a destination floor.

A further embodiment of the present disclosure may include wherein the communication excludes particular access controls.

A further embodiment of the present disclosure may include wherein the communication is based at least in part by a received communication shared from another mobile device.

The foregoing features and elements may be combined in various combinations without exclusivity, unless expressly indicated otherwise. These features and elements as well as the operation thereof will become more apparent in light of the following description and the accompanying drawings. It should be understood, however, the following description and drawings are intended to be exemplary in nature and non-limiting.
