  • Patent number: 9929908
    Abstract: A method, device and system for method of optimizing a feature of a communication network prior to implementing a future service is provided. A plurality of network nodes in the communication network is assigned to a network cluster. At least one value for a respective key performance indicator (KPI) for data exchanged between the network nodes in the network cluster is determined, where the data is associated with a first communication service. And a need for an optimization of a feature of the communication network in response to the value for the KPI being outside of a range, prior to implementation of a second communication service is determined.

  • Patent number: 9686675
    Abstract: A network monitoring node receives one or more data messages regarding User Equipment (UE) from one or more network interfaces for a communication session in the communication network continuously in real-time, determines a subscriber identification (ID) associated with the UE from the one or more data messages regarding the UE, and determines an equipment identification (ID) associated with the UE from the one or more data messages regarding the UE. The network monitoring node further receives a base-key associated with the UE from the one or more data messages regarding the UE, derives a decryption key from the base-key, decrypts a temporary ID associated with the UE from the one or more data messages regarding the UE based on the decryption key, maps the temporary ID with the subscriber ID for the UE, and the subscriber ID with the equipment ID for the UE, and assigns data messages for all further communication sessions to the UE based on the mapping.

  • Patent number: 9674729
    Abstract: A bandwidth estimation algorithm on shared links detects peaks and/or average per-user bandwidth. Estimating is performed at the transport or IP layer with no assistance from lower layer (PHY, MAC, etc.) and the techniques can be used for any of adjusting the level of video optimization to the available bandwidth; driving QoS decisions at the transmitter based on available bandwidth; improving QoS enforcement during transitions among hybrid technologies on a wireless links; and correcting estimates on devices delivering bursty payload.

  • Patent number: 9338674
    Abstract: A system for optimizing communications on a radio network by altering transitions between different link states that includes several modules. The activity, environment, and load module monitor monitors the link layer based on spectral-load metrics and radio-link metrics. The state transition control module determines when user equipment transitions between different states based on the type of user equipment, user equipment battery life, whether the user equipment is connected to an alternating current outlet, a spectral cost, and a backhaul cost. The channel state influencer module uses any of direct messages, ping messages, and keep-alive messages to influence the link state. The policy and preference handler enables or disables transitions based on the bearer technology type, the type of user equipment, the user's subscription plan, and the load level on the network.

  • Patent number: 6567667
    Abstract: A cellular system (100) includes network equipment (102, 104) and user equipment (106). The network equipment can operate to inspect incoming messages from user equipment to identify service applications and direct incoming messages using the domain specified by the user equipment. User equipment can operate to construct messages for communication to a base station, which messages specify one of the circuit switch service domain (206) and the packet switch service domain (204) for the service and transmitting the constructed message to the base. According to one aspect of the system, the network equipment can transmit application and service information to the user equipment, responsive to which the user equipment can select the preferred domain for a message or session.
