Abstract

A method for initiating, via a telecommunications network, a communication or connectivity service between a first location and a second location based on optical data transmission of a user-defined optical signal includes: in a first step, an optical initialization signal is fed or input to an optical data transmission fiber; in a second step, the optical initialization signal is received by an optical safety and policy entity or functionality of the telecommunications network, and an identity of the optical initialization signal is determined by the optical safety and policy entity or functionality; and in a third step, dependent on the determined identity of the optical initialization signal, the communication or connectivity service between the first location and the second location is activated.

First claim

1 . A method for initiating, via a telecommunications network, a communication or connectivity service between a first location and at least a second location based on optical data transmission of a user-defined optical signal,
wherein the telecommunications network comprises a backbone network and/or an aggregation network as well as an access network, and the telecommunications network is used to (1) provide end-user communication services and/or IP connectivity to a multitude of end-users connected to the access network, and (2) connect the first location and the second location via at least access network infrastructure and/or aggregation network infrastructure comprising a plurality of optical network nodes, wherein the telecommunications network comprises, at the first location, at least one optical data transmission fiber for providing the communication or connectivity service, wherein the method comprises the following steps:
in a first step, an optical initialization signal is fed or input to the optical data transmission fiber;
in a second step, the optical initialization signal is received by an optical safety and policy entity or functionality of the telecommunications network, and an identity of the optical initialization signal is determined by the optical safety and policy entity or functionality; and
in a third step, dependent on the determined identity of the optical initialization signal, the communication or connectivity service between the first location and the second location is activated.

2 . The method according to claim 1 , wherein the telecommunications network comprises, at the second location, at least one further optical data transmission fiber for providing the communication or connectivity service,
wherein, between the first and second location, the telecommunications network comprises a transmission functionality regarding the backbone network and/or aggregation network and/or the access network that is based on optical data transmission.

3 . The method according to claim 2 , wherein, in a fourth step, a further optical initialization signal is fed or input to the further optical data transmission fiber, and wherein, in a fifth step, the further optical initialization signal is received by a further optical safety and policy entity or functionality of the telecommunications network, and the identity of the further optical initialization signal is determined by the further optical safety and policy entity or functionality, wherein the establishment or activation of the communication or connectivity service between the first location and the second location is activated dependent on both the determined identity of the optical initialization signal and the determined identity of the further optical initialization signal.

4 . The method according to claim 3 , wherein the establishment or activation of the communication or connectivity service between the first location and the second location is refused in case that identity determination of one or both of the optical initialization signal and the further optical initialization signal fails,
wherein the transmission functionality of the telecommunications network, with regard to the backbone network and/or the aggregation network, is protected by the optical safety and policy entity or functionality and/or by the further optical safety and policy entity or functionality.

5 . The method according to claim 3 , wherein determining the identity of the optical initialization signal and/or of the further optical initialization signal is based on determining physical properties of the initialization signal and/or of the further initialization signal, and involves determining one or a plurality of the following:
the spectrum of the initialization signal and/or of the further initialization signal, the amplitude or the power of the initialization signal and/or of the further initialization signal, timestamp information of the initialization signal and/or of the further initialization signal, or identity information of the initialization signal and/or of the further initialization signal.

6 . The method according to claim 2 , wherein the broadband access network comprises the optical safety and policy entity or functionality connecting the first location and/or the first optical data transmission fiber to the transmission functionality of the telecommunications network, wherein the optical safety and policy entity or functionality provides for
protection of optical transmission functionality, with regard to the backbone network and/or the aggregation network, policy decision functionality, and policy enforcement functionality regarding the user-defined optical signal and/or a further user-defined optical signal, wherein the broadband access network comprises at least one central office point of delivery comprising or coupled with the optical safety and policy entity or functionality, wherein the broadband access network comprises a further central office point of delivery that connects the second location and/or the second optical data transmission fiber to the transmission functionality of the telecommunications network, wherein thereby the communication or connectivity service between the first location and the second location is able to be realized as an optical and transparent user plane point-to-point connection.

7 . The method according to claim 1 , wherein the central office point of delivery comprises a plurality of access nodes and an orchestrator entity or functionality, wherein the plurality of access nodes provide optical network termination functionality to one or a plurality of end-users in view of the end-users being provided with IP connectivity by the telecommunications network, wherein the end-users are connected to the telecommunications network via access network infrastructure which includes optical fiber infrastructure.

8 . The method according to claim 1 , wherein the first location is connected to the central office point of delivery, via the first optical data transmission fiber, using at least one of the following:
a passive optical fiber as a point-to-point link, an active optical fiber, or a passive optical network.
