Abstract: Techniques for leveraging information from a first satellite network to improve communications with a second satellite network are described. According to some embodiments, an endpoint device in an LPWAN communicates with satellites in a GNSS as well as with satellites in another satellite network (e.g., an LPWAN satellite network). By communicating with the GNSS satellites, the endpoint device is able to determine one or more locations in the sky overhead that provide favorable (e.g., unobstructed) communication paths between the endpoint device and satellites in those locations. Then, using ephemeris data for both satellite constellations, the endpoint device determines a time when one or more satellites of the LPWAN satellite network will be in (or near to) one or more of those same locations. At the determined time, the endpoint device transmits data to be received by the one or more satellites of the LPWAN satellite network.

Abstract: In a multi-HSS domain, in which some HSSs support a custom route advance (RA) logic and others do not, a P-CSCF may receive a request for service from a UE associated with one of the HSSs, and send the request to an assigned S-CSCF (S-CSCF1) associated with the UE. Upon failing to receive a response from the S-CSCF1 within a preset time period, the P-CSCF may send the request to the I-CSCF. Based on information included in the request, the I-CSCF may discover an address of a second S-CSCF (S-CSCF2) from the associated HSS and sending the request to the S-CSCF2 based on the discovered address of the S-CSCF2, or send a message indicative of the requested service being unavailable to the P-CSCF.

Abstract: A wireless communication device includes a processor and a memory configured to store a program for establishing a wireless connection with a terminal device. The processor establishes, in accordance with the program stored in the memory, the wireless connection with the terminal device upon request for the wireless connection from one of the wireless communication device and the terminal device. Upon establishment of the wireless connection with the terminal device, the processor queries the terminal device with which the wireless connection is established to check a state of an application program for causing the wireless communication device to execute a specific function. The processor maintains or cuts off the wireless connection with the terminal device based on a state of a response of the terminal device with respect to the query.
