[0051] According to a first embodiment of the present invention, the TNL signaling solution is adapted to be implemented in an IP-based UTRAN. For each connection, an RSVP-TE tunnel is established and standard RSVP-TE objects and messages are used as described above. To achieve bidirectional reservation, one tunnel is established for downstream user traffic and another tunnel is established for upstream user traffic.

[0052] exist Figure 3a The network model between the RNC and the Node B in the case of a full IP-based network according to the first embodiment of the present invention is shown in . The network model includes the RNC, Node Bs (also denoted as base stations) and internal routers. The RNC and Node B are called edge nodes using the terminology of the RMD principle.

[0053] The solution according to the first embodiment of the invention can also be used in the case of a hybrid IP / ATM network, where an Interworking Unit (IWU) is adapted to operate between IP a...

Abstract

The present invention relates to a method and an arrangement for controlling the user plane of a UMTS Terrestrial Radio Access Network, UTRAN, comprising a first edge node connected via a Transport Network Layer to a second edge node, by using Transport Network Layer, TNL, signalling. A radio link is set up by using the Node B Application Part between the first and second edge nodes of the UTRAN, RSVP-TE based TNL signalling messages are transmitted between said first and second edge nodes for each TNL flow, and each TNL flow is identified by using RSVP-TE messages, wherein the object SESSION and SENDER_TEMPLATE comprises an IP based 5-tuple flow information, which is adapted to be used as a TNL flow identity.

Description

[0001] title [0002] transport network control signaling technical field [0003] The present invention relates to a method and apparatus in a mobile telephone network. In particular, the present invention relates to a method and apparatus for transport network layer TNL control signaling in a Universal Mobile Telephony System Terrestrial Radio Access Network (UTRAN). Background technique [0004] The UMTS Terrestrial Radio Access Network (UTRAN) is a Radio Access Network (Radio Access Network RAN) of the third generation mobile network specified by the 3GPP standardization organization. exist Figure 2a The general protocol model of the UTRAN interface is shown in . The protocol model can be divided into two logically independent layers: Radio Network Layer (RNL) and Transport Network Layer (TNL), and is divided orthogonally into user plane and control plane, as in 3GPP TS25.401, 3GPP , TSG RAN: described further in the UTRAN overall description. [0005] according to ...
