Problems solved by technology

[0012] But in case of an n:m relationship between an external access node and an external serving node (serving BNG), the 1:1 relationship is lost, making simple tunneling through the central office delivery point an unsatisfactory solution Program

Abstract

The invention relates to a method for an improved and simplified operation and architecture of a central office point of delivery and / or for the enhanced establishment and / or use of control sessions between network nodes connected to but external to the central office point of delivery within a broadband access network of a telecommunications network, wherein the central office point of delivery and / or the broadband access network comprises a controller node, at least one repository node or repository functionality and a plurality of line termination nodes, wherein a specific line terminationnode of the plurality of line termination nodes is connectable, using an access node port of the specific line termination node to at least one specific network termination node of a plurality of network termination nodes, wherein the broadband access network comprises outside of the central office point of delivery a plurality of external service edge nodes, wherein upon activation of the specific network termination node, being connected to the specific line termination node, a control session is set up or is established, via the controller node, towards a specific external service edge nodeof the plurality of external service edge nodes, a first segment of a control session path being realized between, on the one hand, the specific network termination node or the specific line termination node, and, on the other hand, the controller node, and a second segment of the control session path being realized between the controller node and the specific external service edge node, whereinthe method comprises the following steps: in a first step, the controller node receives, by means of a message sent on the first segment of the control session path, an identity information of the specific network termination node, or of the access node port of the specific line termination node used by the specific network termination node, in a second step, subsequent to the first step, upon a lookup request message being sent to the repository node or repository functionality by the controller node, a lookup response message is sent by the repository node or repository functionality, basedon the identity information of the specific network termination node, or of the access node port of the specific line termination node used by the specific network termination node, the lookup response message comprising an indication of the specific external service edge node, in a third step, subsequent to the second step and based on the indication of the specific external service edge node, the set up or establishment of the second segment of the control session path towards the specific external service edge node is performed.

Description

Background technique [0001] The present invention relates to a method for improving and simplifying the operation and architecture of a central office delivery point and / or for improving access to a central office delivery point connected to, but external to, a broadband access network of a telecommunications network the establishment and / or use of control sessions between network nodes, [0002] Wherein the central office delivery point and / or the broadband access network comprises a controller node, wherein the broadband access network comprises a plurality of external serving edge nodes external to the central office delivery point. [0003] Furthermore, the present invention relates to a telecommunications network for improving and simplifying the operation and architecture of central office delivery points and / or for improving access to central establishment and / or use of control sessions between network nodes at the office delivery point, [0004] Wherein the central o...
