Apparatus, method and computer program product providing priority setting for multi-rat interworking
First Claim
1. An apparatus comprising:
- a receiver configured to receive, from a wireless network operator, a list comprising a plurality of radio access technologies and a plurality of frequency carriers, each of the plurality of frequency carriers being associated with at least one of the plurality of radio access technologies, each of the radio access technologies and its associated frequency carrier being ranked in order of priority;
a memory configured to store the list; and
a user equipment controller configured to consult the stored list comprising the plurality of radio access technologies, compare at least one of a signal measurement and a quality measurement with at least one threshold established for a certain radio access technology of the plurality of radio access technologies, and to select/reselect the certain radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the at least one threshold,wherein the user equipment consults the list to determine the highest ranking radio access technology and its associated frequency carrier, and when the user equipment is not using the highest ranking radio access technology and its associated frequency carrier, the user equipment attempts to switch to the highest ranking radio access technology and its associated frequency carrier.

Abstract
Apparatus, methods and computer program products operate an electronic device to receive through from a wireless communications network a prioritized list of radio access technologies; to store the prioritized list of radio access technologies in a memory of the electronic device; and to consult the prioritized list of radio access technologies during cell selection and reselection operations. In variants the radio access technologies listed in the prioritized list of radio access technologies can be E-UTRAN, UTRAN or GERAN. In a further variant to consult the prioritized list may mean to compare at least one of a signal measurement and a quality measurement with at least one threshold established for a certain radio access technology appearing in the prioritized list, and to select/reselect to the certain radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the threshold.

16. A method for communicating over a plurality of radio access technologies and a plurality of frequency bands, the method comprising:
-
consulting, using a user equipment, a list of the plurality of radio access technologies, each of the plurality of radio access technologies in the list having associated therewith frequency band of the plurality of frequency bands, each radio access technology and its associated frequency band having a predetermined priority level; measuring at least one of a signal measurement and a quality measurement for each of the plurality of radio access technologies in the list; comparing the at least one signal measurement and quality measurement with at least one threshold established for each of the plurality of radio access technologies in the list; and establishing, using the user equipment, a wireless connection with a network using one of radio access technologies of the plurality of radio access technologies and using the frequency band associated with the radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the at least one threshold, wherein the user equipment consults the list to determine the highest ranking radio access technology and its associated frequency carrier, and when the user equipment is not using the highest ranking radio access technology and its associated frequency carrier, the user equipment attempts to switch to the highest ranking radio access technology and its associated frequency carrier. - View Dependent Claims (17, 18, 19)

20. A method for communicating on a wireless device, the method comprising:
-
receiving a list comprising a plurality of radio access technologies and a frequency band associated with each radio access technology of the plurality, each radio access technology and its associated frequency band having a predetermined priority level; reviewing, at the wireless device, the list to determine whether a first radio access technology and frequency band currently being used by the wireless device is the highest predetermined priority level; measuring at least one of a signal measurement and a quality measurement for each of the plurality of radio access technologies in the list; comparing the at least one signal measurement and quality measurement with at least one threshold established for each of the plurality of radio access technologies in the list; switching, at the wireless device, from a first radio access technology and its associated frequency to a second radio access technology and its associated frequency only if the at least one of the signal measurement and the quality measurement exceeds the at least one threshold, wherein the wireless device consults the list to determine the highest ranking radio access technology and its associated frequency carrier, and when the wireless device is not using the highest ranking radio access technology and its associated frequency carrier, the wireless device attempts to switch to the highest ranking radio access technology and its associated frequency carrier. - View Dependent Claims (21, 22, 23)
