ADVANCED ACCESS NETWORK SELECTION METHODS, DEVICES AND COMPUTER PROGRAMS

摘要

In a telecommunication network, a terminal device (100) sends, to a network node (200) hosting an access network discovery and selection function (ANDSF), time zone information (50a), i.e. information about the terminal device's (100) current time zone. Then, the ANDSF node (200) determines access network policies based on the time zone information (50a). In a second solution, the terminal device (100) sends, to the ANDSF node (200), local clock time information (50b), i.e. information (50b) about the terminal device's (100) local clock time; the ANDSF node (200) determines (s40b) time zone information for the terminal device (100) based the received local clock time information (50b) and local clock time information of the ANDSF node (200); and the ANDSF node (200) determines access network policies based on the time zone information. The invention also relates to terminal devices, network nodes and computer programs for carrying out the above- described methods.
