Embodiment Construction

[0058] To facilitate interworking among GERAN and E-UTRAN, the existing GERAN messages "Measurement Report", "Packet Measurement Report", "Enhanced Packet Measurement Report" and "Packet Enhanced Measurement Report" are considered to be UTRAN is used by mobile terminals / UEs with these two capabilities. As mentioned above, there is a blacklist method by which any network cell (access node) that is not on the blacklist but is using an explicitly provided frequency will Will be considered by the UE as a valid candidate for handover (in dedicated mode or dual transfer mode) or cell reselection (in packet transfer mode) of the UE. In order to support such handover or cell reselection, the UE shall notify its serving access nodes in those neighboring cells that are not on the blacklist and are using at least one of the explicitly provided frequencies according to any of the above formats (eg GERAN BTS or UTRAN NB) send measurement reports. A center frequency in E-UTRAN implicitly ...

Abstract

At a user equipment, individual ones of a set of measurements of neighbor cells are associated with individual code points which are relative to a threshold (301) and define a step size (303) that is dynamically determined from a set of possible step sizes. The code points to which the measurements are associated are compiled into a measurement report which is sent to a network. At the network, the code point step size (303) is sent to the user equipment which sends the measurement report to the network. The step size is thus dynamically determined from a set of possible step sizes. The network selects, based on the received measurement report, one of the neighbor cells for handover of the user equipment. In an embodiment, the threshold (301) is determined from an offset value sent by the network to the user equipment. Methods, apparatus, and stored computer programs are described for both user equipment and network side embodiments.

Description

technical field [0001] Exemplary and non-limiting embodiments of the present invention relate generally to wireless communication systems, methods, devices and computer programs, and more particularly to measurement reporting of neighboring cells in wireless communication systems; in particular inter-RAT cell measurements ( For example, report E-UTRAN cells in GERAN). Background technique [0002] This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include concepts that may be pursued, but not necessarily concepts that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] The following abbreviations which may be found in the specification and / or drawings are defined as follows: [00...
