Problems solved by technology

This can result in reduced awareness for some subscribers, while others will experience no change
[0007] The problem is thus that current network solutions such as QoS are extremely terminal-centric and do not take full advantage of existing network architectures

Embodiment Construction

[0026] Embodiments of the invention with further developments described below are to be considered as examples only and in no way to limit the scope of protection offered by the patent claims.

[0027] The invention relates to a method for transferring at least one service or IP session from a first access to a second access. It also involves Gateway and Policy Control Function PCF which serve the same purpose. Even though the detailed description describes the method by which these functions are performed, those skilled in the art recognize that such functions as are suitable for performing these method steps are also disclosed in the description.

[0028] figure 1 A network in which the invention is preferably implemented is shown. figure 1 A System Architecture Evolution (SAE) core network is shown. The components of the network communicate with each other via reference points and interfaces (Gn, Gp, S3, S4, S10, S11, S1u, S5, Gxa, Gx, Rx, S2a, SGi), which will not be de...

Abstract

The present invention relates to a method for moving at least one service or an IP session from a first access to a second access,comprising the following steps: -a Gateway, GW, routes (25) a data packet flow between a Packet Data Network, PDN, and a User Equipment, UE, for said service or IP session over the first access, -the GW monitors (26) the data packet flow between the PDN and the UE to detect the network performance of the first access, -the GWmoves (27) the routing of the data packet flow to the second access when the network performance goes below a threshold.

Description

technical field [0001] The invention relates to a method for transferring at least one service or IP session from a first access to a second access. It also involves Gateway and Policy Control Function PCF which serve the same purpose. Background technique [0002] Terminals (User Equipment / Mobile Stations) are often equipped with the ability to access via 2G / 3G and WLAN. Other devices such as laptops may have the capability of access via HSPA (High Speed ​​Packet Access) / LTE (Long Term Evolution), WLAN (Wireless LAN) and Ethernet. Typically, terminals or laptops use different accesses, one at a time. And more importantly, only one type of access is used at a time for a given service or a given IP session. [0003] Currently, 3GPP EPS (Evolved Packet System), also known as 3GPP SAE, is defining a solution for how session continuity can be achieved when a UE transfers between different accesses. This can mean, for example, that a service that was running over cellular is ...
