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 test calls from elevator emergency telephones, comprising:

receiving, at an elevator emergency call receiver unit, an incoming call attempt from an elevator emergency telephone, the call attempt including caller line identification, CLI, information;

detecting the CLI information included in the received call attempt, and performing one of;

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.

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, wherein c) further comprises:

establishing a data communication protocol with the elevator emergency telephone.

4. The method according to claim 3, wherein c) further comprises:

receiving an identification of the elevator emergency telephone via the established data communication protocol.

5. The method according to claim 4, wherein c) further comprises:

receiving type information about the received call attempt.

6. The method according to claim 4, wherein c) further comprises:

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

7. A computer program stored on a computer readable medium and comprising code adapted to cause the steps of claim 1 when executed on said elevator emergency call receiver unit.

8. An elevator emergency call receiver unit, comprising:

at least one processor; and

at least one memory including computer program code;

wherein at least one memory and the computer program code being configured to, with the at least one processor, cause the elevator emergency call receiver unit at least to perform;

receiving an incoming call attempt from an elevator emergency telephone, the call attempt including caller line identification, CLI, information;

detecting the CLI information included in the received call attempt, and performing one of;

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.

9. The elevator emergency call receiver unit according to claim 8, 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 unit to perform:

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

10. The elevator emergency call receiver unit according to claim 8, 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 unit to perform:

establishing, in c), a data communication protocol with the elevator emergency telephone.

11. The elevator emergency call receiver unit according to claim 10, 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 unit to perform:

receiving an identification of the elevator emergency telephone via the established data communication protocol.

12. The elevator emergency call receiver unit according to claim 10, 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 unit to perform:

receiving type information about the received call attempt.

13. The elevator emergency call receiver unit according to claim 11, 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 unit to perform:

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

14. A system, comprising:

an elevator emergency telephone; and

a test call database,

wherein further comprising an elevator emergency call receiver unit according to claim 8.
