Method for receiving store and forward satellite operation parameter

A user equipment (UE), the UE comprising:

• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• while a timer T3451 is running, not initiating a non-access stratum (NAS) procedure over a S&F satellite cell in a tracking area identifier (TAI) list assigned to the UE, unless the S&F satellite cell broadcasts a same satellite identifier (ID) broadcasted by the S&F satellite cell from which an accept message was received;
• if the UE supports a S&F satellite operation, receiving a S&F satellite operation parameter in an accept message;
• if an estimated S&F uplink delivery time duration field is present in the S&F satellite operation parameter, storing the estimated S&F uplink delivery time duration provided in the S&F operation parameter and deleting any previous stored value;
• and
• if a first field in the S&F satellite operation parameter is set to “S&F monitoring list present”, deleting any previously stored value for a S&F monitoring list of a current Public Land Mobile Network (PLMN) and storing a S&F monitoring list value for the current PLMN, provided in the S&F satellite operation parameter.

A semiconductor chipset, comprising:

• at least one processor;
• and
• at least one memory capable of storing instructions and being connected electrically to the at least one processor operably,
• wherein operations, performed when the instructions are executed by the at least one processor, includes:
• while a timer T3451 is running, not initiating a non-access stratum (NAS) procedure over a S&F satellite cell in a tracking area identifier (TAI) list assigned to the UE, unless the S&F satellite cell broadcasts a same satellite identifier (ID) broadcasted by the S&F satellite cell from which an accept message was received;
• if the UE supports a S&F satellite operation, receiving a S&F satellite operation parameter in an accept message;
• if an estimated S&F uplink delivery time duration field is present in the S&F satellite operation parameter, storing the estimated S&F uplink delivery time duration provided in the S&F operation parameter and deleting any previous stored value;
• and
• if a first field in the S&F satellite operation parameter is set to “S&F monitoring list present”, deleting any previously stored value for a S&F monitoring list of a current Public Land Mobile Network (PLMN) and storing a S&F monitoring list value for the current PLMN, provided in the S&F satellite operation parameter.
