Cellular service recovery using cell-specific service history

An wireless device, comprising:

• an antenna;
• a radio coupled to the antenna;
• and
• a processing element coupled to the radio;
• wherein the wireless device is configured to:
• store information indicating cellular service recovery time on each of one or more cellular service loss occasions for each of one or more cells from which the wireless device has previously lost cellular service;
• receive cell-specific service history information for one or more previous serving cells of a companion device to the accessory device;
• determine that cellular service loss is currently occurring, wherein the current cellular service loss is occurring from a cell for which information indicating cellular service recovery time on each of one or more previous cellular service loss occasions is stored;
• attempt to recover cellular service, wherein at least one parameter used as part of the attempt to recover cellular service is selected based at least in part on the stored information indicating cellular service recovery time on each of the one or more previous cellular service loss occasions for the cell from which the current cellular service loss is occurring, wherein the cell-specific service history information for the one or more previous serving cells of the companion device is used during the attempt to recover cellular service.

A memory medium comprising program instructions that, when executed, cause an accessory device to:

• maintain cell-specific service history information for one or more previous serving cells of the accessory device;
• receive cell-specific service history information for one or more previous serving cells of a companion device to the accessory device;
• determine that the accessory device has lost cellular service on a current serving cell;
• and
• attempt to recover cellular service, wherein the cell-specific service history information for the one or more previous serving cells of the accessory device is used during the attempt to recover cellular service, wherein the cell-specific service history information for the one or more previous serving cells of the companion device is used during the attempt to recover cellular service.
