  • Patent number: 11349938
    Abstract: A non-MNO PSP network maintains a table that maps external subscriber identifiers of UEs to intermediate subscriber identifiers of the UEs on an interface between the non-MNO PSP network and NHN(s). The non-MNO PSP network obtains an SCEF-related message including either an external subscriber identifier or an intermediate subscriber identifier for the UE. Using the table, the non-MNO PSP network forwards the SCEF-message to a serving NHN or to an external application. In another embodiment, an NHN maintains a table that maps internal identifiers of UEs within the NHN to intermediate subscriber identifiers that identify the UEs on an interface between the NHN and non-MNO PSP(s). The NHN obtains an SCEF-related message that includes an intermediate subscriber identifier or an internal identifier for the UE. Using the table, the NHN either processes the SCEF-related message within the NHN, or forwards the SCEF-related message to a non-MNO PSP outside the NHN.

  • Patent number: 11336561
    Abstract: An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common “sync” value published to all the ports of the IP router.
