Prioritizing radio access technologies

A method of selecting cells to be measured by a user equipment, the method comprising:

• storing in a computer readable memory a prioritized measurement list in which are represented at least two radio access technologies, each entry in the prioritized measurement list defining a unique combination of frequency layer arid radio access technology for a serving cell and for neighbor cells;
• and
• based on at least signal strength of the serving ceil, selecting from a neighbor list according to the prioritized measurement list a set of entries for measuring according to a selection rule, wherein the selection rule provides:
• for the case in which the signal strength of the serving ceil is relatively high, the selected set is a first set of the prioritized measurement list;
• and
• for the case in which the signal strength of the serving ceil is relatively low, the selected set is a second set of the prioritized measurement list, the second set excluding all frequency layers of the prioritized measurement list belonging to the radio access technology having a highest priority or alternatively a lowest priority, and the second set different from the first set.

A non-transitory memory storing a computer program, the computer program comprising a set of instructions which, when executed by a computing system, causes the computing system to perform the steps of:

• storing in a computer readable memory a prioritized measurement list in which are represented at least two radio access technologies, each entry in the prioritized measurement list defining a unique combination of frequency layer and radio access technology for a serving cell and for neighbor cells;
• and
• based on at least signal strength of the serving cell, selecting from a neighbor list according to the prioritized measurement list a set of entries for measuring according to a selection rule, wherein the selection rule provides:
• for the case in which the signal strength of the serving ceil is relatively higher, the selected set is a first set of the prioritized measurement list;
• and
• for the case in which the signal strength of the serving ceil is relatively lower, the selected set is a second set of the prioritized measurement list, the second set excluding all frequency layers of the prioritized measurement list belonging to the radio access technology having a highest priority or alternatively a lowest priority, and the second set different from the first set.
