Abstract
Aspects relate to delay management techniques to handle delays introduced by high latency links in non-terrestrial networks for non-access stratum (NAS) mobility management and session management procedures. The NAS timers within the user equipment (UE) and core network utilized for mobility management and session management procedures may be configured with different durations, such as a normal duration, an extended duration, or a reduced duration, based on whether the UE is connected to a terrestrial or non-terrestrial radio access network (RAN), one or more capabilities of the UE, and/or the various RAN types (e.g., terrestrial or non-terrestrial) within a registration area that the UE is located in.
Claims47
A method for managing delays by a wireless communication device, the method comprising:
- attaching to a first base station in a first radio access network within a registration area, the first radio access network comprising a network type, wherein the network type comprises a terrestrial network type or a non-terrestrial network type;
- transmitting a registration request to a core network via the first base station, wherein the registration request comprises a network type indication that indicates whether the wireless communication device is capable of supporting both the terrestrial network type and the non-terrestrial network type;
- selecting a respective duration of each timer of a set of one or more timers for communication with the core network via the first base station based on at least one of the network type or a timer selection instruction received from the core network;
- and
- performing at least one of a mobility management procedure or a session management procedure with the core network using the set of one or more timers.
