Embodiment Construction

[0031] figure 2 A radio access network RAN ​​with an infrastructure according to the invention is shown in . The RAN has a Radio Network Controller RNC separated into different entities distributed at different locations in the network. At least one of these functional entities is the control plane server CPS located at the master node of the RNC, and there are several user plane servers UPS located near the base station NB. The server CPS or UPS is either used to manage the control plane function in the RAN, or used to manage the user plane function in the RAN. Therefore, the CPS is installed at a more central location, while the UPSs are preferably installed separately, since each of them is connected to the sub-equipment of the base station NB. Because subdevices are simple, only the figure 2One subdevice is shown in , denoted as Node B.

[0032] All UPSs are connected to the CPS located at the RNC master node. Also, the server CPS manages the control plane functions...

Abstract

In evolved radio access network (RAN) architectures the user and the control planes are separated into different network elements (CPS,UPS). <??>In order to hide this separation (RNC split) from the core network (CN) a solution is presented here which also enables to hide serving radio network subsystem user plane relocation from the core network (CN). Only the new introduced network element (TAMS) containing the mapping function interfaces with the core network (CN). This network element is preferably a transport address mapping server (TAMS) which is able to distinguish control and user plane information belonging to different users and which distributes it to the appropriate control plane server (CPS) or user plane server (UPS). In the other direction the transport address mapping server (TAMS) receives control and user plane information from different servers (CPS,UPS) and forwards it to the appropriate core network (CN) node. <IMAGE>

Description

technical field [0001] The invention relates to a wireless access network and network components for providing mobile communication services. Background technique [0002] The structure and design of modern radio access networks are becoming more and more complex, such as UTRAN (UMTS Terrestrial Radio Access Network; UMTS: Universal Mobile Telecommunications System). The overall mobile radio system has many different entities, devices and components, namely user terminals, radio base stations, at least one radio network controller for controlling a cluster of radio base stations, and switching equipment, such as for establishing connections to the Public Switched Telephone Network (PSTN) circuit-switched connection to a mobile switching center or similar. At the same time, routers for establishing packet-switched connections to IP-based networks, especially the World Wide Web, can also be installed. [0003] The radio access network, also called RAN, mainly consists of bas...
