AI Technical Summary

Problems solved by technology

In solutions using the same radio interface for data and voice, there is a disadvantage, because the infrastructure needs to handle both data and voice through the same infrastructure equipment, and thus allocate unnecessary resources reducing the possible data traffic rate

Embodiment Construction

[0038] exist figure 1 In , reference numeral 1 generally designates a mobile station MS 2 communicating wirelessly with a gateway 3 to a communication network 10 . In addition to the gateway 3 , the communication network comprises communication channels 4 , 6 and 8 , a communication infrastructure 5 , a tunnel termination device TTD 7 and a further communication infrastructure 9 . Depending on the communication interfaces and protocols applied, the communication infrastructure 5, 9 will look different. Several examples will be shown below; however, those skilled in the art will recognize that none of these limit the invention to these embodiments. A mobile station MS 1 (often referred to as a mobile node (MN), such as a cell phone or a laptop or some other user equipment (UE)) communicates over some wireless interface 2 (such as GPRS, UMTS, WCDMA, WLAN, WPAN, Mobile @Home, WiMAX, MowLAN or a similar interface compatible with packet-based communication protocols communicates ...

Abstract

The present invention relates to a method, devices, infrastructure network, and computer program for doing policy based routing in a tunnel terminating device (7, 200, 405) for separating CS and PS traffic and increasing the perceived bandwidth by reducing capacity problems in a supporting node in the network (10). Communication data is packed into an IPSec tunnel in a mobile station (1, 401) andsent to the tunnel-terminating device in an IP based tunnel (410), e.g. an IPSec tunnel. The tunnel terminating device is arranged to perform policy based routing and transfer CS and PS traffic to different destinations depending on network structure and packet data.

Description

technical field [0001] The present invention relates to methods, nodes, computer programs and networks for high speed data traffic in telecommunication networks, in particular to tunneling of data traffic from mobile nodes to central nodes. Background technique [0002] Current and future mobile stations are moving towards combining data and voice services into the infrastructure network. This stems from customers' need to be "connected" wherever they are. They want to be able to use the phone to communicate with colleagues, family and others, and to have connections to e-mail, Web services, file servers and other similar data applications. However, there is an increasing demand from users that this should be done from the same mobile station, which must be set up to handle voice applications and preferably high speed data connections. [0003] The general trend in mobile stations is in this direction, so for example there are multiple solutions for cellular phones with hi...
