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.

Claims

1. A method of processing a test call from an elevator emergency telephone, the method comprising:

receiving, at an elevator emergency call receiver, a call attempt from the elevator emergency telephone, the call attempt being sent as a call setup signaling message of the test call and including caller line identification (CLI) information;

detecting the CLI information included in the call attempt prior to answering the test call;

determining whether processing of the test call is complete by determining if the elevator emergency telephone has released the call attempt within a set time period;

answering the test call to enable the elevator emergency telephone to further process the test call in response to determining that the processing of the test call is not complete; and

further processing the test call by receiving an identification of the elevator emergency telephone different from the CLI information after answering the test call.

2. The method according to claim 1, further comprising:

updating a test call database based on the detected CLI information.

3. The method according to claim 1, further comprising:

establishing a data communication protocol with the elevator emergency telephone.

4. The method according to claim 3, wherein the receiving further comprises:

receiving type information about the received call attempt.

5. The method according to claim 2, wherein the updating further comprises:

updating the test call database based at least on the received identification of the elevator emergency telephone.

6. A non-transitory computer readable medium including computer readable instruction that, when executed on a processor of a elevator emergency call receiver, cause the processor to,

receive, at the elevator emergency call receiver, a call attempt from an elevator emergency telephone during a test call, the call attempt being sent as a call setup signaling message of the test call and including caller line identification (CLI) information,

detecting the CLI information included in the call attempt prior to answering the test call,

determining whether processing of the test call is complete by determining if the elevator emergency telephone has released the call attempt within a set time period,

answering the test call to enable the elevator emergency telephone to further process the test call in response to determining that the processing of the test call is not complete, and

further processing the test call by receiving an identification of the elevator emergency telephone different from the CLI information after answering the test call.

7. An elevator emergency call receiver, comprising:

at least one memory including computer program code; and

at least one processor configured to execute the computer program code to,

receive a call attempt during a test call from an elevator emergency telephone, the call attempt including caller line identification (CLI) information,

detect the CLI information included in the call attempt,

determine whether the processing of the test call is completed la determining if the elevator emergency telephone has released the call attempt within a set time period,

answer the test call to enable the elevator emergency telephone to continue the processing of the test call if the processing of the test call is not complete, and

further process the test call by receiving an identification of the elevator emergency telephone different from the CLI information after answering the test call.

8. The elevator emergency call receiver according to claim 7, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the elevator emergency call receiver to:

update a test call database based on the CLI information.

9. The elevator emergency call receiver according to claim 7, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the elevator emergency call receiver to:

establish a data communication protocol with the elevator emergency telephone.

10. The elevator emergency call receiver according to claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the elevator emergency call receiver to:

receive type information about the call attempt.

11. The elevator emergency call receiver according to claim 7, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the elevator emergency call receiver to:

update a test call database based at least on the identification of the elevator emergency telephone.

12. A system, comprising:

an elevator emergency telephone;

a test call database; and

the elevator emergency call receiver according to claim 7.
