Abstract

In a telecommunications network including one or more mobile terminals in communicable relation to a mobile network and a data network such that data from the mobile terminals is transmitted towards the data network via the mobile network, a method of directing data from the mobile terminals towards the data network includes: providing an alternative data route towards the data network which bypasses at least a portion of the mobile network; comparing the data from the mobile terminals with selection criteria; and using the result of the comparison to selectively redirecting at least a portion of the data generated by the mobile terminals onto the alternative data route. The alternative data route may be configured to bypass at least a portion of the core component of the mobile network, and data that is redirected is data which is not required to be processed by the bypassed core network component.

9. The method of claim 8, wherein the alternative data route includes a route via a public internet.

10. The method of claim 1, wherein the first selection criteria is whether the mobile terminal is in a home network thereof.

11. The method of claim 1, further comprising determining whether the one or more mobile terminals associated with the data are operating in a home network or are roaming and determining whether one or more offloading criteria associated with the data are met.

12. In a communications network including one or more mobile terminals configured to communicate over a mobile network with a data network, such that data transmitted between the one or more mobile terminals and the data network is transmitted via the mobile network, a data route selection module for directing data between the one or more mobile terminals and the data network, the module configured to:
