Abstract
A method and apparatus for implementing Idle and Connected Mode mobility to and from a Home evolved Node-B (HNB) in a wireless environment. Methods to implement differentiated charging when accessing HNBs, as well as the criteria used to make a cell reselection decision when an HNB is detected, criteria for making a handoff decision and methods to indicate charging and other policies/preferences and configurations to a wireless transmit/receive unit (WTRU).
Claims18
A method for reselection for use in a wireless transmit/receive unit (WTRU), the method comprising:
- maintaining a list of one or more identifiers (IDs) including one or more IDs indicating previously visited HNBs;
- searching for one or more candidate cells including candidate cells associated with any of the one or more IDs indicating the previously visited HNBs on non-serving frequencies;
- performing measurements on the one or more candidate cells including the candidate cells associated with any of the one or more IDs indicating the previously visited HNBs to generate selection criteria identifying one or more suitable candidate cells for reselection;
- determining whether at least one additional selection criteria associated with a characteristic of the identified one or more suitable candidate cells indicates the identified one or more suitable candidate cells has priority over a serving cell associated with a serving frequency;
- and
- determining whether to reselect to the identified one or more suitable candidate cells based on the serving frequency, the measurements, and the at least one additional selection criteria.
A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to maintain a list of allowed Home Node B (HNB) identifiers (IDs) including HNB IDs of previously visited HNBs;
- and
- the processor, a transmitter, and a receiver configured to:
- search for one or more candidate cells including candidate cells associated with any of the allowed HNB IDs including the HNB IDs of the previously visited HNBs on non-serving frequencies;
- perform measurements on the one or more candidate cells including the candidate cells associated with any of the allowed HNB IDs including the HNB IDs of the previously visited HNBs to generate selection criteria identifying one or more suitable candidate cells for reselection;
- determine whether at least one additional selection criteria associated with a characteristic of the identified one or more suitable candidate cells indicates the identified one or more suitable candidate cells has priority over a serving cell associated with a serving frequency;
- and
- determine whether to reselect from the serving cell to the identified one or more suitable candidate cells based on the serving frequency, the measurements, and the at least one additional selection criteria.
