Benefits of technology

The present invention provides a way for people who are testing an elevator call to receive emergency phone calls more easily without having to pay extra money or other expensive equipment.

Problems solved by technology

This patent describes a problem with testing elevator emergencies through regular phone calls. Specifically, current methods involve sending outgoing calls over dial-up modems, making them expensive and requiring multiple devices. Additionally, existing solutions like CLI are not always effective because they don't work properly if the caller has been previously confirmed. Therefore, this patent proposes introducing a method to allow users to recognize their elevator emergency calls even without having to answer each call individually.

Embodiment Construction

[0036]Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0037]FIG. 1a is a signaling diagram illustrating a method according to an embodiment of the present invention. In this embodiment, the elevator emergency telephone 310a is not configured to wait that its test call is answered. Furthermore, the elevator emergency telephone 310a does not share its telephone line outside its building with any other elevator emergency telephone.

[0038]An incoming call attempt from the elevator emergency telephone 310a is received at an elevator emergency call receiver unit 330, step 11. The call attempt includes caller line identification, CLI, information, including at least the telephone number of the calling party which in this embodiment is the elevator emergency telephone 310a. The call attempt may be sent e.g. as a ‘call setup’ signaling message (including the telephone number of the called party) from

Abstract

The invention allows utilizing Caller Line Identification (CLI) feature in receiving test emergency calls from any kind of elevator emergency telephones. A call attempt including CLI information from an elevator emergency telephone is received at an elevator emergency call receiver unit. The CLI information is detected. Then, one of the following is performed: a) disconnecting the call attempt to complete the test call processing; b) in response to detecting the call attempt being released by the elevator emergency telephone within a predetermined time period, determining that the test call processing is completed; and c) in response to detecting the call attempt not being released by the elevator emergency telephone within the predetermined time period, answering the incoming call to enable the elevator emergency telephone to continue the test call processing.
