  • Patent number: 9537824
    Abstract: An apparatus and method for enhancing the infrastructure of a network such as the Internet is disclosed. A packet interceptor/processor apparatus is coupled with the network so as to be able to intercept and process packets flowing over the network. Further, the apparatus provides external connectivity to other devices that wish to intercept packets as well. The apparatus applies one or more rules to the intercepted packets which execute one or more functions on a dynamically specified portion of the packet and take one or more actions with the packets. The apparatus is capable of analyzing any portion of the packet including the header and payload. Actions include releasing the packet unmodified, deleting the packet, modifying the packet, logging/storing information about the packet or forwarding the packet to an external device for subsequent processing. Further, the rules may be dynamically modified by the external devices.

  • Patent number: 9467258
    Abstract: The herein suggested technology gives principles for how HARQ-feedback, or corresponding, can be predicted using distributed data from scheduling decisions and optionally also from radio measurements. This data can be sent between base stations after the finished scheduling, and does not require a backhaul with very low latency. The predicted HARQ feedback can then be used for scheduling a retransmission or new transmission sooner than the actual HARQ feedback is received.

  • Patent number: 9444854
    Abstract: Systems and methods for a Session Initiation Protocol (SIP) router are described. In one aspect, the SIP router receives a SIP INVITE for an incoming call to a target mobile subscriber. Responsive to receiving the SIP INVITE, the SIP router identifies, via a Send Routing Information for Short Message (SRI/SM) request to a Home Location Register, a first address of a serving switch in a circuit-switched mobile network; a mobile telephony device associated with the target mobile subscriber is currently location-updated on the serving switch. The SIP router maps the first address to a second address for the serving switch; the second address being a SIP address. Using the SIP address, the SIP router sends the received SIP INVITE to a SIP interface of the serving switch. The serving switch being configured to process the received SIP INVITE and the incoming call to the target mobile subscriber.
