Embodiment Construction

[0037] In its preferred form, the invention is applied to a Node B network element forming part of a UTRA-based radiocommunication network for mobile telephony or other data transfer types, the operative part of which is at figure 2 shown inside. The core network (CN) is connected to the UTRAN by the Iu interface. In UTRAN, the Iu interface terminates at a Radio Network Controller (RNC). The RNCs are connected to each other by an Iur interface.

[0038] figure 2 Two types of RNCs are shown: Serving RNC (SRNC) and Drift RNC (DRNC). The user equipment is connected to the Node B by the air interface Uu and the Node B is connected to the RNC by Iub. All interfaces are specified for the network to work properly. The Iub interface is specified to use ATM and ALL2 transport mechanisms.

[0039] In the context of the preferred embodiment, figure 1 The network operation shown will be compared to the figure 1 to describe where a Node B network element (ie base station) receive...

Abstract

A method of assigning resources within a network element within which a traffic termination point or AAL2 termination point has been established is described. The network element accepts a connection request, and it is then ascertained whether available resources have sufficient capacity to establish the requested connection. In the event that there is sufficient capacity, it is ascertained whether the termination points defined in relation to the available resources fragments the resources such that the connection cannot be established. If the resources are so fragmented, then one or more of the termination points are reallocated, without breaking the connection to which they relate, thereby defragmenting the resources sufficiently that the requested connection can be established.

Description

technical field [0001] The present invention relates to communication protocols, in particular to Asynchronous Transfer Mode (ATM) as defined in the technical specifications related to the UTRAN (UMTS Terrestrial Radio Access Network) standard defined by the Third Generation Partnership Project (3GPP). [0002] The present invention has been developed to provide additional features to the currently accepted and proposed technical specifications defined by 3GPP, and the invention will be described herein with reference to these technical specifications. But it should be understood that telecommunications is a rapidly developing field, and the present invention should be applicable to new and different standards and technical specifications evolving from various currently accepted or proposed standards. Background technique [0003] The various uses of ATM are defined within technical specifications published by 3GPP. Of particular relevance is 3GPP TS 25.433 V3.3.0, the cont...
