Abstract

A test procedure for an emergency call network includes the following steps: A test user connection is provided between a test user and a test site and an integrated test environment. Location data are assigned to a target location of the test user, wherein such target location is to be emulated by the integrated test environment. An emergency operator connection is provided between the integrated test environment and an emergency operator in an emergency call center of the emergency call network using the assigned location data. The test user connection and the emergency operator connection are synchronized to establish an end-to-end call connection between the test user and the emergency operator. By using these steps, the expenses for performing a test procedure for an emergency call network are lowered. A test system also is presented for performing such test procedure.

Claims (35)

1. A test procedure for an emergency call network, including the following steps:

providing a test user connection between a test user at a test site and an integrated test environment,

assigning location data to a target location of the test user wherein such target location is emulated by the integrated test environment,

providing an emergency operator connection between the integrated test environment and an emergency operator in an emergency call center of the emergency call network using the assigned location data,

synchronizing the test user connection and the emergency operator connection to establish an end-to-end call connection between the test user and the emergency operator,

wherein during the test procedure a plurality of test calls is performed by the test user from one and the same location, wherein location data are assigned which are representative for different emulated locations.

2. A test procedure according to claim 1 , wherein the location data includes an emulated network cell ID.

3. A test procedure according to claim 1 , wherein at least one of the group of

the test user connection, and

the emergency operator connection

is established as a VoLTE standard connection.

4. A test procedure according to claim 1 , wherein at least one of the group of

the test user connection, and

the emergency operator connection

is established via a core network.

5. A test procedure according to claim 1 , wherein at least one of the group of

the test user connection, and

the emergency operator connection

is established via a S1 standard interface.

6. A test system for performing a test procedure for an emergency call network, including the following steps:

providing a test user connection between a test user at a test site and an integrated test environment,

assigning location data to a target location of the test user wherein such target location is emulated by the integrated test environment,

providing an emergency operator connection between the integrated test environment and an emergency operator in an emergency call center of the emergency call network using the assigned location data,

synchronizing the test user connection and the emergency operator connection to establish an end-to-end call connection between the test user and the emergency operator,

wherein during the test procedure a plurality of test calls is performed by the test user from one and the same location, wherein location data are assigned which are representative for different emulated locations.

7. A test system for performing a test procedure for an emergency call network, the system comprising:

a central processor,

a local processor in signal connection with the central processor,

a mobile phone in signal connection with the local processor, and

a core network over which the mobile phone communicates with the local processor and the central processor, the core network comprising an emergency call center,

wherein the mobile phone is configured to establish a test user connection between a test user at a test site and the central processor over the core network,

wherein the central processor is configured to assign location data to a target location of the test user and emulate the target location,

wherein the central processor is configured to provide an emergency operator connection between the central processor and an emergency operator in the emergency call center through the core network using the assigned location data,

wherein the local processor is configured to synchronize the test user connection and the emergency operator connection to establish an end-to-end call connection between the test user and the emergency operator,

wherein a plurality of test calls are placed during the test procedure by the test user from one and the same location, wherein location data are assigned which are representative for different emulated locations.
