Problems solved by technology

[0005] Although the user may be in the access area of ​​multiple data networks at the same time, the user may only be able to access one of these data networks with his / her mobile terminal
For example, a user's mobile terminal may be configured to communicate with only one of these data networks, for example because his / her mobile terminal is configured as a GSM cellular terminal and therefore cannot communicate with the local CDMA cellular network

Embodiment Construction

[0035] The entirety of US Provisional Patent Application No. 61 / 011,482, filed January 26, 2008, by P. Feder and A. Rajkumar is hereby incorporated by reference.

[0036] Although data networks typically require authentication of a user before authorizing establishment of a communication session with the user's terminal, embodiments of the data network herein enable some types of authentication-free communication sessions to be established between the data network and the user's terminal.

[0037] Here, an unauthenticated communication session refers to a communication session between the data network and the user's terminal (A) when the data network does not have a certificate to authenticate and authorize the user terminal, or (B) after the data network has refused to authorize the user terminal. Communication session established between. Examples of credentials of a user terminal may include authentication keys, SIM (Subscriber Identity Module) and / or USIM (Universal SIM) c...

Abstract

One method includes setting up an authenticated communication session between a mobile terminal and a first core data network. The method includes acquiring, at the first core data network, supplementary access data usable by the mobile terminal to set up a non-authenticated communication session with a second data network and then, transmitting the supplementary access data from the first core data network to the mobile terminal. The second data network is accessible to the mobile terminal.

Description

[0001] This application claims the benefit of US Provisional Patent Application No. 61 / 011,482, filed January 16, 2008. technical field [0002] The present invention generally relates to devices and methods for communicating with data networks. Background technique [0003] The aspects presented in this section may contribute to a better understanding of the invention. Accordingly, the statements in this section are to be read as such, and not as an admission as to what is or is not prior art in this regard. [0004] In many common situations, a user mobile device may be in the access areas of multiple data networks. For example, a user may be in the access area of ​​two different types of data networks at the same time, eg, a CDMA cellular telephone network and a wireless WIFI data network. Typically, accessing a data network involves performing an initial setup procedure in which data is transferred between the user's mobile terminal and the data network to be accessed....
