Inter-radio access technology (rat)

A wireless communication method, comprising:

• triggering, by a communication node, an inter-Radio Access Technology (RAT) cell selection or reselection process;
• and
• selecting, after the triggering, a frequency or a RAT to communicate with a second cell,
• wherein the frequency is selected from one or more frequencies previously accessed by the communication node or wherein the RAT is selected from one or more RATs previously accessed by the communication node.

A wireless communication method, comprising:

• transmitting, by a network node, a first set of parameters for a first type of communication nodes or a second set of parameters for a second type of communication nodes,
• wherein a first sensitivity to power consumption of the first type of communication nodes is lower than a second sensitivity to power consumption of the second type of communication nodes, and
• wherein the first set of parameters or the second set of parameters include any one or more of:
• a list of frequencies,
• priority values associated with the frequencies, and
• a threshold value indicative of a quality of transmission that triggers a measurement.

A wireless communication method, comprising:

• receiving, by a communication node, a first set of parameters for a first type of communication nodes or a second set of parameters for a second type of communication nodes,
• wherein a first sensitivity to power consumption of the first type of communication nodes is lower than a second sensitivity to power consumption of the second type of communication nodes, and
• wherein the first set of parameters or the second set of parameters include any one or more of:
• a list of frequencies,
• priority values associated with the frequencies, and
• a threshold value indicative of a quality of transmission that triggers a measurement.

A wireless communication method, comprising:

• receiving, by a communication node, a plurality of sets of parameters for inter-Radio Access Technology (RAT) cell selection or reselection, wherein each set of parameters includes any one or more of:
• priority values associated with frequencies,
• a first threshold to select a first frequency having a higher priority than a priority of a serving frequency used by the communication,
• a second threshold to select a second frequency having a lower priority than the priority of the serving frequency used by the communication, a timer to evaluate one or more of the plurality of frequencies for a reselection process, and
• a third threshold to select a cell having a lower priority than a priority of a currently serving cell;
• and
• selecting one set of parameters according to a coverage condition of the communication node and/or a bandwidth condition of the communication node.

A wireless communication method, comprising:

• transmitting, by a network node, a plurality of sets of parameters for inter-Radio Access Technology (RAT) cell selection or reselection, wherein each set of parameters includes any one or more of:
• priority values associated with frequencies,
• a first threshold to select a first frequency having a higher priority than a priority of a serving frequency used by the communication,
• a second threshold to select a second frequency having a lower priority than the priority of the serving frequency used by the communication,
• a timer to evaluate one or more of the plurality of frequencies for a reselection process, and
• a third threshold to select a cell having a lower priority than a priority of a currently serving cell.

A wireless communication method, comprising:

• determining, by a communication node, that a radio quality of a first cell serving the communication node is lower than a threshold;
• measuring, after the determining, one or more radio qualities corresponding to one or more additional cells;
• selecting a second cell from the one or more additional cells;
• and
• demoting a position of the first cell on a list arranged according to the radio quality and the one or more radio qualities of the first cell and the one or more additional cells, respectively.
