Inter-frequency cell reselection

A device comprising:

• a communication interface;
• a memory, wherein the memory stores instructions;
• and
• a processor, wherein the processor executes the instructions to:
• camp on a current cell of a wireless network;
• store cell reselection parameters that have values that change in correspondence to a change of remaining battery power of the device;
• select a first set of at least one of one or more candidate frequency bands or one or more candidate frequencies based on a first parameter of the cell reselection parameters, wherein the first parameter indicates at least one of one or more candidate frequency bands or one or more candidate frequencies from which the device can select for cell reselection;
• perform inter-frequency measurement pertaining to the at least one of the one or more candidate frequency bands or the one or more candidate frequencies;
• count a number of inter-frequency measurements performed;
• filter a result of the inter-frequency measurement;
• determine whether a cell reselection criteria has been satisfied based on one or more signal threshold values;
• select a new cell in response to a determination that the cell reselection criteria has been met;
• enter a rest period, based on a second parameter of the cell reselection parameters, in response to selecting the new cell, wherein the second parameter indicates a duration of the rest period when cell reselection is successful;
• and
• determine whether to select a second set of at least one of one or more candidate frequency bands or one or more candidate frequencies indicated by the first parameter in response to a determination that the cell reselection criteria has not been met.

A non-transitory storage medium that stores instructions executable by a processor of a device to:

• attach and register to a wireless network via a network device of the wireless network;
• store cell reselection parameters that have values that change in correspondence to a change of remaining battery power of the device;
• select a first set of at least one of one or more candidate frequency bands or one or more candidate frequencies based on a first parameter of the cell reselection parameters, wherein the first parameter indicates at least one of one or more candidate frequency bands or one or more candidate frequencies from which the device can select for cell reselection;
• perform inter-frequency measurement pertaining to the at least one of the one or more candidate frequency bands or the one or more candidate frequencies;
• count a number of inter-frequency measurements performed;
• filter a result of the inter-frequency measurement;
• determine whether a cell reselection criteria has been satisfied based on one or more signal threshold values;
• select a new cell in response to a determination that the cell reselection criteria has been met;
• enter a rest period, based on a second parameter of the cell reselection parameters, in response to selecting the new cell, wherein the second parameter indicates a duration of the rest period when cell reselection is successful;
• and
• determine whether to select a second set of at least one of one or more candidate frequency bands or one or more candidate frequencies indicated by the first parameter in response to a determination that the cell reselection criteria has not been met.
